164-519: Philosophy ('love of wisdom' in Ancient Greek ) is a systematic study of general and fundamental questions concerning topics like existence , reason , knowledge , value , mind , and language . It is a rational and critical inquiry that reflects on its own methods and assumptions. Historically, many of the individual sciences , such as physics and psychology , formed part of philosophy. However, they are considered separate academic disciplines in
328-423: A linguistic therapy. According to Ludwig Wittgenstein , for instance, philosophy aims at dispelling misunderstandings to which humans are susceptible due to the confusing structure of ordinary language . Phenomenologists , such as Edmund Husserl , characterize philosophy as a "rigorous science" investigating essences . They practice a radical suspension of theoretical assumptions about reality to get back to
492-537: A pitch accent . In Modern Greek, all vowels and consonants are short. Many vowels and diphthongs once pronounced distinctly are pronounced as /i/ ( iotacism ). Some of the stops and glides in diphthongs have become fricatives , and the pitch accent has changed to a stress accent . Many of the changes took place in the Koine Greek period. The writing system of Modern Greek, however, does not reflect all pronunciation changes. The examples below represent Attic Greek in
656-426: A certain manner by being wholeheartedly committed to this manner. Virtues contrast with vices , which are their harmful counterparts. Virtue theorists usually say that the mere possession of virtues by itself is not sufficient. Instead, people should manifest virtues in their actions. An important factor is the practical wisdom, also called phronesis , of knowing when, how, and which virtue to express. For example,
820-428: A certain standpoint. Moral standpoints may differ between persons, cultures, and historical periods. For example, moral statements like "Slavery is wrong" or "Suicide is permissible" may be true in one culture and false in another. Some moral relativists say that moral systems are constructed to serve certain goals such as social coordination. According to this view, different societies and different social groups within
984-399: A characterization of what is good and then define what is right in terms of what is good. For example, classical utilitarianism says that pleasure is good and that the action leading to the most overall pleasure is right. Consequentialism has been discussed indirectly since the formulation of classical utilitarianism in the late 18th century. A more explicit analysis of this view happened in
1148-454: A child on fire for fun, normative ethics aims to find more general principles that explain why this is the case, like the principle that one should not cause extreme suffering to the innocent , which may itself be explained in terms of a more general principle. Many theories of normative ethics also aim to guide behavior by helping people make moral decisions . Theories in normative ethics state how people should act or what kind of behavior
1312-470: A diversity of viewpoints. A universal moral norm is seen as valid if all rational discourse participants do or would approve. This way, morality is not imposed by a single moral authority but arises from the moral discourse within society. This discourse should aim to establish an ideal speech situation to ensure fairness and inclusivity. In particular, this means that discourse participants are free to voice their different opinions without coercion but are at
1476-542: A doctor diagnoses a disease based on the observed symptoms. Logic also investigates incorrect forms of reasoning. They are called fallacies and are divided into formal and informal fallacies based on whether the source of the error lies only in the form of the argument or also in its content and context. Metaphysics is the study of the most general features of reality , such as existence, objects and their properties , wholes and their parts , space and time , events , and causation . There are disagreements about
1640-515: A fifth major dialect group, or it is Mycenaean Greek overlaid by Doric, with a non-Greek native influence. Regarding the speech of the ancient Macedonians diverse theories have been put forward, but the epigraphic activity and the archaeological discoveries in the Greek region of Macedonia during the last decades has brought to light documents, among which the first texts written in Macedonian , such as
1804-444: A great variety of methods to arrive at philosophical knowledge. They include conceptual analysis , reliance on common sense and intuitions , use of thought experiments , analysis of ordinary language , description of experience , and critical questioning . Philosophy is related to many other fields, including the sciences, mathematics , business , law , and journalism . It provides an interdisciplinary perspective and studies

#17328376838131968-508: A lack of practical wisdom may lead courageous people to perform morally wrong actions by taking unnecessary risks that should better be avoided. Different types of virtue ethics differ on how they understand virtues and their role in practical life. Eudaimonism is the original form of virtue theory developed in Ancient Greek philosophy and draws a close relation between virtuous behavior and happiness. It states that people flourish by living
2132-540: A means to promote their self-interest. Ethical egoism is often criticized as an immoral and contradictory position. Normative ethics has a central place in most religions . Key aspects of Jewish ethics are to follow the 613 commandments of God according to the Mitzvah duty found in the Torah and to take responsibility for societal welfare . Christian ethics puts less emphasis on following precise laws and teaches instead
2296-694: A metaphysical foundation of ethics. The modern period in Chinese philosophy began in the early 20th century and was shaped by the influence of and reactions to Western philosophy. The emergence of Chinese Marxism —which focused on class struggle , socialism , and communism —resulted in a significant transformation of the political landscape. Another development was the emergence of New Confucianism , which aims to modernize and rethink Confucian teachings to explore their compatibility with democratic ideals and modern science. Traditional Japanese philosophy assimilated and synthesized ideas from different traditions, including
2460-458: A part of intellectual history , but it also investigates questions not covered by intellectual history such as whether the theories of past philosophers are true and have remained philosophically relevant. The history of philosophy is primarily concerned with theories based on rational inquiry and argumentation; some historians understand it in a looser sense that includes myths , religious teachings , and proverbial lore. Influential traditions in
2624-550: A person should tell the truth even in specific cases where lying would lead to better consequences. Another disagreement is between actual and expected consequentialism. According to the traditional view, only the actual consequences of an act affect its moral value. One difficulty of this view is that many consequences cannot be known in advance. This means that in some cases, even well-planned and intentioned acts are morally wrong if they inadvertently lead to negative outcomes. An alternative perspective states that what matters are not
2788-401: A pleasurable experience has a high value if it has a high intensity and lasts for a long time. A common criticism of Bentham's utilitarianism argued that its focus on the intensity of pleasure promotes an immoral lifestyle centered around indulgence in sensory gratification. Mill responded to this criticism by distinguishing between higher and lower pleasures. He stated that higher pleasures, like
2952-543: A prefix /e-/, called the augment . This was probably originally a separate word, meaning something like "then", added because tenses in PIE had primarily aspectual meaning. The augment is added to the indicative of the aorist, imperfect, and pluperfect, but not to any of the other forms of the aorist (no other forms of the imperfect and pluperfect exist). The two kinds of augment in Greek are syllabic and quantitative. The syllabic augment
3116-464: A situation, regardless of their specific role or position. Immanuel Kant (1724–1804) is one of the most well-known deontologists. He states that reaching outcomes that people desire, such as being happy, is not the main purpose of moral actions. Instead, he argues that there are universal principles that apply to everyone independent of their desires. He uses the term categorical imperative for these principles, saying that they have their source in
3280-725: A small set of basic rules that address all or at least the most important moral considerations. One difficulty for systems with several basic principles is that these principles may conflict with each other in some cases and lead to ethical dilemmas . Distinct theories in normative ethics suggest different principles as the foundation of morality. The three most influential schools of thought are consequentialism , deontology , and virtue ethics . These schools are usually presented as exclusive alternatives, but depending on how they are defined, they can overlap and do not necessarily exclude one another. In some cases, they differ in which acts they see as right or wrong. In other cases, they recommend
3444-425: A society construct different moral systems based on their diverging purposes. Emotivism provides a different explanation, stating that morality arises from moral emotions, which are not the same for everyone. Moral nihilists deny the existence of moral facts. They reject the existence of both objective moral facts defended by moral realism and subjective moral facts defended by moral relativism. They believe that

#17328376838133608-533: A strong Northwest Greek influence, and can in some respects be considered a transitional dialect, as exemplified in the poems of the Boeotian poet Pindar who wrote in Doric with a small Aeolic admixture. Thessalian likewise had come under Northwest Greek influence, though to a lesser degree. Pamphylian Greek , spoken in a small area on the southwestern coast of Anatolia and little preserved in inscriptions, may be either
3772-611: A variety of arguments. Deductive arguments are mainly studied by formal logic. An argument is deductively valid if the truth of its premises ensures the truth of its conclusion. Deductively valid arguments follow a rule of inference , like modus ponens , which has the following logical form : " p ; if p then q ; therefore q ". An example is the argument "today is Sunday; if today is Sunday then I don't have to go to work today; therefore I don't have to go to work today". The premises of non-deductive arguments also support their conclusion, although this support does not guarantee that
3936-557: A virtuous life. Eudaimonist theories often hold that virtues are positive potentials residing in human nature and that actualizing these potentials results in leading a good and happy life. Agent-based theories, by contrast, see happiness only as a side effect and focus instead on the admirable traits and motivational characteristics expressed while acting. This is often combined with the idea that one can learn from exceptional individuals what those characteristics are. Feminist ethics of care are another form of virtue ethics. They emphasize
4100-510: A vowel or /n s r/ ; final stops were lost, as in γάλα "milk", compared with γάλακτος "of milk" (genitive). Ancient Greek of the classical period also differed in both the inventory and distribution of original PIE phonemes due to numerous sound changes, notably the following: The pronunciation of Ancient Greek was very different from that of Modern Greek . Ancient Greek had long and short vowels ; many diphthongs ; double and single consonants; voiced, voiceless, and aspirated stops ; and
4264-488: Is a combination of different parts and attempts to identify what those parts are. An influential theory in this area claims that knowledge has three components: it is a belief that is justified and true . This theory is controversial and the difficulties associated with it are known as the Gettier problem . Alternative views state that knowledge requires additional components, like the absence of luck; different components, like
4428-509: Is a common issue in relation to the sources of knowledge and the justification they offer. It is based on the idea that beliefs require some kind of reason or evidence to be justified. The problem is that the source of justification may itself be in need of another source of justification. This leads to an infinite regress or circular reasoning . Foundationalists avoid this conclusion by arguing that some sources can provide justification without requiring justification themselves. Another solution
4592-487: Is a moral obligation to refrain from lying. Because it relies on consent, contractualism is often understood as a patient-centered form of deontology. Famous social contract theorists include Thomas Hobbes , John Locke , Jean-Jacques Rousseau , and John Rawls . Discourse ethics also focuses on social agreement on moral norms but says that this agreement is based on communicative rationality . It aims to arrive at moral norms for pluralistic modern societies that encompass
4756-559: Is a set of essential features shared by all parts of philosophy. Others see only weaker family resemblances or contend that it is merely an empty blanket term. Precise definitions are often only accepted by theorists belonging to a certain philosophical movement and are revisionistic according to Søren Overgaard et al. in that many presumed parts of philosophy would not deserve the title "philosophy" if they were true. Some definitions characterize philosophy in relation to its method, like pure reasoning. Others focus on its topic, for example, as
4920-412: Is about what people ought to do rather than what they actually do, what they want to do, or what social conventions require. As a rational and systematic field of inquiry, ethics studies practical reasons why people should act one way rather than another. Most ethical theories seek universal principles that express a general standpoint of what is objectively right and wrong. In a slightly different sense,
5084-418: Is added to stems beginning with consonants, and simply prefixes e (stems beginning with r , however, add er ). The quantitative augment is added to stems beginning with vowels, and involves lengthening the vowel: Some verbs augment irregularly; the most common variation is e → ei . The irregularity can be explained diachronically by the loss of s between vowels, or that of the letter w , which affected

5248-464: Is also concerned with the moral evaluation of character traits and institutions. It explores what the standards of morality are and how to live a good life. Philosophical ethics addresses such basic questions as "Are moral obligations relative?"; "Which has priority: well-being or obligation?"; and "What gives life meaning?" The main branches of ethics are meta-ethics , normative ethics , and applied ethics . Meta-ethics asks abstract questions about
5412-476: Is an expression of the philosopher's love of wisdom and has the aim of improving one's well-being by leading a reflective life. For example, the Stoics saw philosophy as an exercise to train the mind and thereby achieve eudaimonia and flourish in life. As a discipline, the history of philosophy aims to provide a systematic and chronological exposition of philosophical concepts and doctrines. Some theorists see it as
5576-476: Is better than an unequal distribution even if the aggregate good is the same. There are disagreements about which consequences should be assessed. An important distinction is between act consequentialism and rule consequentialism. According to act consequentialism, the consequences of an act determine its moral value. This means that there is a direct relation between the consequences of an act and its moral value. Rule consequentialism, by contrast, holds that an act
5740-410: Is between naturalism and non-naturalism. Naturalism states that moral properties are natural properties accessible to empirical observation . They are similar to the natural properties investigated by the natural sciences , like color and shape. Some moral naturalists hold that moral properties are a unique and basic type of natural property. Another view states that moral properties are real but not
5904-449: Is closely related to the disciplines of logic and linguistics. The philosophy of language rose to particular prominence in the early 20th century in analytic philosophy due to the works of Frege and Russell. One of its central topics is to understand how sentences get their meaning. There are two broad theoretical camps: those emphasizing the formal truth conditions of sentences and those investigating circumstances that determine when it
6068-405: Is concerned with meaning , understanding , or the clarification of language. According to one view, philosophy is conceptual analysis , which involves finding the necessary and sufficient conditions for the application of concepts. Another definition characterizes philosophy as thinking about thinking to emphasize its self-critical, reflective nature. A further approach presents philosophy as
6232-448: Is considered by some linguists to have been closely related to Greek . Among Indo-European branches with living descendants, Greek is often argued to have the closest genetic ties with Armenian (see also Graeco-Armenian ) and Indo-Iranian languages (see Graeco-Aryan ). Ancient Greek differs from Proto-Indo-European (PIE) and other Indo-European languages in certain ways. In phonotactics , ancient Greek words could end only in
6396-461: Is correct. They do not aim to describe how people normally act, what moral beliefs ordinary people have, how these beliefs change over time, or what ethical codes are upheld in certain social groups. These topics belong to descriptive ethics and are studied in fields like anthropology , sociology , and history rather than normative ethics. Some systems of normative ethics arrive at a single principle covering all possible cases. Others encompass
6560-456: Is embedded in and relative to social and cultural contexts. Pragmatists tend to give more importance to habits than to conscious deliberation and understand morality as a habit that should be shaped in the right way. Postmodern ethics agrees with pragmatist ethics about the cultural relativity of morality. It rejects the idea that there are objective moral principles that apply universally to all cultures and traditions. It asserts that there
6724-532: Is found in Jainism , which has non-violence as its principal virtue. Duty is a central aspect of Hindu ethics and is about fulfilling social obligations, which may vary depending on a person's social class and stage of life . Confucianism places great emphasis on harmony in society and sees benevolence as a key virtue. Taoism extends the importance of living in harmony to the whole world and teaches that people should practice effortless action by following

The term philosophy acquired the meanings of "advanced study of the speculative subjects ( logic , ethics , physics , and metaphysics )", "deep wisdom consisting of love of truth and virtuous living", "profound learning as transmitted by the ancient writers", and "the study of the fundamental nature of knowledge , reality , and existence , and
7052-470: Is morally right. Its main branches include normative ethics , applied ethics , and metaethics . Normative ethics aims to find general principles that govern how people should act. Applied ethics examines concrete ethical problems in real-life situations, such as abortion , treatment of animals , and business practices . Metaethics explores the underlying assumptions and concepts of ethics. It asks whether there are objective moral facts, how moral knowledge
7216-736: Is no one coherent ethical code since morality itself is irrational and humans are morally ambivalent beings. Postmodern ethics instead focuses on how moral demands arise in specific situations as one encounters other people. Ethical egoism is the view that people should act in their self-interest or that an action is morally right if the person acts for their own benefit. It differs from psychological egoism , which states that people actually follow their self-interest without claiming that they should do so. Ethical egoists may act in agreement with commonly accepted moral expectations and benefit other people, for example, by keeping promises, helping friends, and cooperating with others. However, they do so only as
7380-651: Is not interested in which actions are right but in what it means for an action to be right and whether moral judgments are objective and can be true at all. It further examines the meaning of morality and other moral terms. Metaethics is a metatheory that operates on a higher level of abstraction than normative ethics by investigating its underlying assumptions. Metaethical theories typically do not directly judge which normative ethical theories are correct. However, metaethical theories can still influence normative theories by examining their foundational principles. Metaethics overlaps with various branches of philosophy. On
7544-446: Is one of the earliest forms of consequentialism. It arose in the 5th century BCE and argued that political action should promote justice as a means to increase the welfare of the people. The most well-known form of consequentialism is utilitarianism. In its classical form, it is an act consequentialism that sees happiness as the only source of intrinsic value. This means that an act is morally right if it produces "the greatest good for
7708-443: Is possible, and how moral judgments motivate people. Influential normative theories are consequentialism , deontology , and virtue ethics . According to consequentialists, an act is right if it leads to the best consequences. Deontologists focus on acts themselves, saying that they must adhere to duties , like telling the truth and keeping promises. Virtue ethics sees the manifestation of virtues , like courage and compassion , as
7872-473: Is presented by coherentists , who state that a belief is justified if it coheres with other beliefs of the person. Many discussions in epistemology touch on the topic of philosophical skepticism , which raises doubts about some or all claims to knowledge. These doubts are often based on the idea that knowledge requires absolute certainty and that humans are unable to acquire it. Ethics, also known as moral philosophy, studies what constitutes right conduct . It
8036-422: Is primarily concerned with normative statements about what ought to be the case, in contrast to descriptive statements , which are about what is the case. Duties and obligations express requirements of what people ought to do. Duties are sometimes defined as counterparts of the rights that always accompany them. According to this view, someone has a duty to benefit another person if this other person has
8200-438: Is right if it follows a certain set of rules. Rule consequentialism determines the best rules by considering their outcomes at a community level. People should follow the rules that lead to the best consequences when everyone in the community follows them. This implies that the relation between an act and its consequences is indirect. For example, if telling the truth is one of the best rules, then according to rule consequentialism,
8364-417: Is sometimes understood as a proper science in its own right. According to some naturalistic philosophers , such as W. V. O. Quine , philosophy is an empirical yet abstract science that is concerned with wide-ranging empirical patterns instead of particular observations. Science-based definitions usually face the problem of explaining why philosophy in its long history has not progressed to the same extent or in

Ancient Greek Ancient Greek ( Ἑλληνῐκή , Hellēnikḗ ; [hellɛːnikɛ́ː] ) includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek ( c. 1400–1200 BC ), Dark Ages ( c. 1200–800 BC ),
8692-437: Is that actions are in tune with those duties and not what consequences they have. Virtue theorists judge actions based on how the moral character of the agent is expressed. According to this view, actions should conform to what an ideally virtuous agent would do by manifesting virtues like generosity and honesty . Logic is the study of correct reasoning . It aims to understand how to distinguish good from bad arguments . It
8856-467: Is the 1687 book Philosophiæ Naturalis Principia Mathematica by Isaac Newton . This book referred to natural philosophy in its title, but it is today considered a book of physics. The meaning of philosophy changed toward the end of the modern period when it acquired the more narrow meaning common today. In this new sense, the term is mainly associated with philosophical disciplines like metaphysics, epistemology, and ethics. Among other topics, it covers

Classical utilitarianism was initially formulated by Jeremy Bentham at the end of the 18th century and further developed by John Stuart Mill . Bentham introduced the hedonic calculus to assess the value of consequences. Two key aspects of the hedonic calculus are the intensity and the duration of pleasure. According to this view,
9184-408: Is the philosophical study of ethical conduct and investigates the fundamental principles of morality . It aims to discover and justify general answers to questions like "How should one live?" and "How should people act?", usually in the form of universal or domain-independent principles that determine whether an act is right or wrong. For example, given the particular impression that it is wrong to set
9348-561: Is the study of correct reasoning and explores how good arguments can be distinguished from bad ones. Metaphysics examines the most general features of reality , existence, objects , and properties . Other subfields are aesthetics , philosophy of language , philosophy of mind , philosophy of religion , philosophy of science , philosophy of mathematics , philosophy of history , and political philosophy . Within each branch, there are competing schools of philosophy that promote different principles, theories, or methods. Philosophers use

Kant states that actions motivated in such a way are unconditionally good, meaning that they are good even in cases where they result in undesirable consequences. Divine command theory says that God is the source of morality. It states that moral laws are divine commands and that to act morally
9676-481: Is to obey and follow God's will . While all divine command theorists agree that morality depends on God, there are disagreements about the precise content of the divine commands, and theorists belonging to different religions tend to propose different moral laws. For example, Christian and Jewish divine command theorists may argue that the Ten Commandments express God's will while Muslims may reserve this role for

Epistemology is primarily interested in declarative knowledge or knowledge of facts, like knowing that Princess Diana died in 1997. But it also investigates practical knowledge , such as knowing how to ride a bicycle, and knowledge by acquaintance , for example, knowing a celebrity personally. One area in epistemology is the analysis of knowledge . It assumes that declarative knowledge

In its search for exact criteria, it examines the structure of arguments to determine whether they are correct or incorrect. Informal logic uses non-formal criteria and standards to assess the correctness of arguments. It relies on additional factors such as content and context. Logic examines

He translated and interpreted many works of Aristotle and Neoplatonists in his attempt to show that there is a harmony between reason and faith . Avicenna (980–1037 CE) also followed this goal and developed a comprehensive philosophical system to provide a rational understanding of reality encompassing science, religion, and mysticism.

Further topics include the essence of works of art and the processes involved in creating them. The philosophy of language studies the nature and function of language . It examines the concepts of meaning , reference , and truth. It aims to answer questions such as how words are related to things and how language affects human thought and understanding. It

Deontologists are interested in which actions are right and often allow that there is a gap between what is right and what is good. Many focus on prohibitions and describe which acts are forbidden under any circumstances. Agent-centered deontological theories focus on the person who acts and the duties they have. Agent-centered theories often focus on

From the Hellenistic period ( c. 300 BC ), Ancient Greek was followed by Koine Greek , which is regarded as a separate historical stage, though its earliest form closely resembles Attic Greek , and its latest form approaches Medieval Greek . There were several regional dialects of Ancient Greek; Attic Greek developed into Koine. Ancient Greek

Based on the conclusions drawn by several studies and findings such as Pella curse tablet , Emilio Crespo and other scholars suggest that ancient Macedonian was a Northwest Doric dialect , which shares isoglosses with its neighboring Thessalian dialects spoken in northeastern Thessaly . Some have also suggested an Aeolic Greek classification. The Lesbian dialect

Most tenses display all four moods and three voices, although there is no future subjunctive or imperative. Also, there is no imperfect subjunctive, optative or imperative. The infinitives and participles correspond to the finite combinations of tense, aspect, and voice. The indicative of past tenses adds (conceptually, at least)

They contend that this base-level of experience provides the foundation for higher-order theoretical knowledge, and that one needs to understand the former to understand the latter. An early approach found in ancient Greek and Roman philosophy is that philosophy is the spiritual practice of developing one's rational capacities. This practice
12136-532: The 20th century, virtue ethics experienced a resurgence thanks to philosophers such as Elizabeth Anscombe , Philippa Foot , Alasdair MacIntyre , and Martha Nussbaum . There are many other schools of normative ethics in addition to the three main traditions. Pragmatist ethics focuses on the role of practice and holds that one of the key tasks of ethics is to solve practical problems in concrete situations. It has certain similarities to utilitarianism and its focus on consequences but concentrates more on how morality
12300-404: The 20th century, when the term was coined by G. E. M. Anscombe . Consequentialists usually understand the consequences of an action in a very wide sense that includes the totality of its effects. This is based on the idea that actions make a difference in the world by bringing about a causal chain of events that would not have existed otherwise. A core intuition behind consequentialism is that

Ancient pronunciation cannot be reconstructed with certainty, but Greek from the period is well documented, and there is little disagreement among linguists as to the general nature of the sounds that the letters represent. /oː/ raised to [uː] , probably by the 4th century BC. Greek, like all of the older Indo-European languages , is highly inflected. It is highly archaic in its preservation of Proto-Indo-European forms. In ancient Greek, nouns (including proper nouns) have five cases ( nominative , genitive , dative , accusative , and vocative ), three genders ( masculine , feminine , and neuter ), and three numbers (singular, dual , and plural ). Verbs have four moods ( indicative , imperative , subjunctive , and optative ) and three voices (active, middle, and passive ), as well as three persons (first, second, and third) and various other forms. Verbs are conjugated through seven combinations of tenses and aspect (generally simply called "tenses"):

The Renaissance period started in the 14th century and saw a renewed interest in schools of ancient philosophy, in particular Platonism . Humanism also emerged in this period. The modern period started in the 17th century. One of its central concerns

It was introduced into the English language during the Middle English period through the Old French term moralité . The terms ethics and morality are usually used interchangeably but some philosophers distinguish between
12956-490: The Archaic period of ancient Greek (see Homeric Greek for more details): Μῆνιν ἄειδε, θεά, Πηληϊάδεω Ἀχιλῆος οὐλομένην, ἣ μυρί' Ἀχαιοῖς ἄλγε' ἔθηκε, πολλὰς δ' ἰφθίμους ψυχὰς Ἄϊδι προΐαψεν ἡρώων, αὐτοὺς δὲ ἑλώρια τεῦχε κύνεσσιν οἰωνοῖσί τε πᾶσι· Διὸς δ' ἐτελείετο βουλή· ἐξ οὗ δὴ τὰ πρῶτα διαστήτην ἐρίσαντε Ἀτρεΐδης τε ἄναξ ἀνδρῶν καὶ δῖος Ἀχιλλεύς. The beginning of Apology by Plato exemplifies Attic Greek from
13120-601: The Classical period of ancient Greek. (The second line is the IPA , the third is transliterated into the Latin alphabet using a modern version of the Erasmian scheme .) Ὅτι [hóti Hóti μὲν men mèn ὑμεῖς, hyːmêːs hūmeîs, Ethics Ethics is the philosophical study of moral phenomena. Also called moral philosophy , it investigates normative questions about what people ought to do or which behavior
13284-540: The Dorians. The Greeks of this period believed there were three major divisions of all Greek people – Dorians, Aeolians, and Ionians (including Athenians), each with their own defining and distinctive dialects. Allowing for their oversight of Arcadian, an obscure mountain dialect, and Cypriot, far from the center of Greek scholarship, this division of people and language is quite similar to the results of modern archaeological-linguistic investigation. One standard formulation for
13448-430: The actual consequences but the expected consequences. This view takes into account that when deciding what to do, people have to rely on their limited knowledge of the total consequences of their actions. According to this view, a course of action has positive moral value despite leading to an overall negative outcome if it had the highest expected value , for example, because the negative outcome could not be anticipated or
13612-529: The agent. It is controversial whether agent-relative moral theories, like ethical egoism , should be considered as types of consequentialism. There are many different types of consequentialism. They differ based on what type of entity they evaluate, what consequences they take into consideration, and how they determine the value of consequences. Most theories assess the moral value of acts. However, consequentialism can also be used to evaluate motives , character traits , rules, and policies . Many types assess
13776-550: The aorist. Following Homer 's practice, the augment is sometimes not made in poetry , especially epic poetry. The augment sometimes substitutes for reduplication; see below. Almost all forms of the perfect, pluperfect, and future perfect reduplicate the initial syllable of the verb stem. (A few irregular forms of perfect do not reduplicate, whereas a handful of irregular aorists reduplicate.) The three types of reduplication are: Irregular duplication can be understood diachronically. For example, lambanō (root lab ) has
13940-419: The augment when it was word-initial. In verbs with a preposition as a prefix, the augment is placed not at the start of the word, but between the preposition and the original verb. For example, προσ(-)βάλλω (I attack) goes to προσ έ βαλoν in the aorist. However compound verbs consisting of a prefix that is not a preposition retain the augment at the start of the word: αὐτο(-)μολῶ goes to ηὐ τομόλησα in
14104-570: The basic assumptions underlying moral claims are misguided. Some moral nihilists conclude from this that anything is allowed. A slightly different view emphasizes that moral nihilism is not itself a moral position about what is allowed and prohibited but the rejection of any moral position. Moral nihilism, like moral relativism, recognizes that people judge actions as right or wrong from different perspectives. However, it disagrees that this practice involves morality and sees it as just one type of human behavior. A central disagreement among moral realists
14268-438: The basic limits of human understanding". Before the modern age, the term philosophy was used in a wide sense. It included most forms of rational inquiry, such as the individual sciences , as its subdisciplines. For instance, natural philosophy was a major branch of philosophy. This branch of philosophy encompassed a wide range of fields, including disciplines like physics, chemistry , and biology . An example of this usage
14432-435: The beginning of the 20th century. It discusses topics such as ethnophilosophy , négritude , pan-Africanism , Marxism, postcolonialism , the role of cultural identity, relativism , African epistemology , and the critique of Eurocentrism . Philosophical questions can be grouped into several branches. These groupings allow philosophers to focus on a set of similar topics and interact with other thinkers who are interested in
14596-417: The best action for someone with a good salary would be to donate 70% of their income to charity, it would be morally wrong for them to only donate 65%. Satisficing consequentialism, by contrast, only requires that an act is "good enough" even if it is not the best possible alternative. According to this view, it is possible to do more than one is morally required to do. Mohism in ancient Chinese philosophy
14760-459: The conclusion is true. One form is inductive reasoning . It starts from a set of individual cases and uses generalization to arrive at a universal law governing all cases. An example is the inference that "all ravens are black" based on observations of many individual black ravens. Another form is abductive reasoning . It starts from an observation and concludes that the best explanation of this observation must be true. This happens, for example, when
14924-612: The consequences of the general theories developed by normative ethics in specific situations, for example, in the workplace or for medical treatments. Within contemporary normative ethics, consequentialism, deontology , and virtue ethics are influential schools of thought. Consequentialists judge actions based on their consequences. One such view is utilitarianism , which argues that actions should increase overall happiness while minimizing suffering. Deontologists judge actions based on whether they follow moral duties, such as abstaining from lying or killing. According to them, what matters
15088-421: The consequences. A related approach is to characterize consequentialism not in terms of consequences but in terms of outcome, with the outcome being defined as the act together with its consequences. Most forms of consequentialism are agent-neutral. This means that the value of consequences is assessed from a neutral perspective, that is, acts should have consequences that are good in general and not just good for
15252-423: The deficient state of cowardice and the excessive state of recklessness . Aristotle held that virtuous action leads to happiness and makes people flourish in life. Stoicism emerged about 300 BCE and taught that, through virtue alone, people can achieve happiness characterized by a peaceful state of mind free from emotional disturbances. The Stoics advocated rationality and self-mastery to achieve this state. In
15416-611: The dialect of Sparta ), and Northern Peloponnesus Doric (including Corinthian ). All the groups were represented by colonies beyond Greece proper as well, and these colonies generally developed local characteristics, often under the influence of settlers or neighbors speaking different Greek dialects. After the conquests of Alexander the Great in the late 4th century BC, a new international dialect known as Koine or Common Greek developed, largely based on Attic Greek , but with influence from other dialects. This dialect slowly replaced most of
15580-517: The dialects is: West vs. non-West Greek is the strongest-marked and earliest division, with non-West in subsets of Ionic-Attic (or Attic-Ionic) and Aeolic vs. Arcadocypriot, or Aeolic and Arcado-Cypriot vs. Ionic-Attic. Often non-West is called 'East Greek'. Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian Greek had come under
15744-510: The divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period. They have the same general outline but differ in some of the detail. The only attested dialect from this period is Mycenaean Greek , but its relationship to the historical dialects and the historical circumstances of the times imply that the overall groups already existed in some form. Scholars assume that major Ancient Greek period dialect groups developed not later than 1120 BC, at
15908-421: The emergence and application of formal logic , the focus on the role of language as well as pragmatism , and movements in continental philosophy like phenomenology, existentialism , and post-structuralism . The 20th century saw a rapid expansion of academic philosophy in terms of the number of philosophical publications and philosophers working at academic institutions . There was also a noticeable growth in
16072-474: The emergence of non-Vedic teachings, like Buddhism and Jainism . Buddhism was founded by Gautama Siddhartha (563–483 BCE), who challenged the Vedic idea of a permanent self and proposed a path to liberate oneself from suffering . Jainism was founded by Mahavira (599–527 BCE), who emphasized non-violence as well as respect toward all forms of life. The subsequent classical period started roughly 200 BCE and
16236-441: The exploration of the nature of reality and the ways of arriving at knowledge. Chinese philosophy focuses principally on practical issues in relation to right social conduct, government, and self-cultivation . Major branches of philosophy are epistemology , ethics , logic , and metaphysics . Epistemology studies what knowledge is and how to acquire it. Ethics investigates moral principles and what constitutes right conduct. Logic
16400-406: The features that all entities have in common. Specific metaphysics is interested in different kinds of being, the features they have, and how they differ from one another. An important area in metaphysics is ontology . Some theorists identify it with general metaphysics. Ontology investigates concepts like being , becoming , and reality. It studies the categories of being and asks what exists on
16564-531: The fundamental principle of morality. Ethics is closely connected to value theory , which studies the nature and types of value , like the contrast between intrinsic and instrumental value . Moral psychology is a related empirical field and investigates psychological processes involved in morality, such as reasoning and the formation of character . Descriptive ethics describes the dominant moral codes and beliefs in different societies and considers their historical dimension. The history of ethics started in
16728-405: The future should be shaped to achieve the best possible outcome. The act itself is usually not seen as part of the consequences. This means that if an act has intrinsic value or disvalue, it is not included as a factor. Some consequentialists see this as a flaw, saying that all value-relevant factors need to be considered. They try to avoid this complication by including the act itself as part of
16892-429: The greatest number" by increasing happiness and reducing suffering. Utilitarians do not deny that other things also have value, like health, friendship, and knowledge. However, they deny that these things have intrinsic value. Instead, they say that they have extrinsic value because they affect happiness and suffering. In this regard, they are desirable as a means but, unlike happiness, not as an end. The view that pleasure
17056-525: The history of philosophy include Western , Arabic–Persian , Indian , and Chinese philosophy . Other philosophical traditions are Japanese philosophy , Latin American philosophy , and African philosophy . Western philosophy originated in Ancient Greece in the 6th century BCE with the pre-Socratics . They attempted to provide rational explanations of the cosmos as a whole. The philosophy following them
17220-421: The human mind and culture rather than as subjective constructs or expressions of personal preferences and cultural norms . Moral realists accept the claim that there are objective moral facts. This view implies that moral values are mind-independent aspects of reality and that there is an absolute fact about whether a given action is right or wrong. A consequence of this view is that moral requirements have
17384-415: The importance of interpersonal relationships and say that benevolence by caring for the well-being of others is one of the key virtues. Influential schools of virtue ethics in ancient philosophy were Aristotelianism and Stoicism . According to Aristotle (384–322 BCE), each virtue is a golden mean between two types of vices: excess and deficiency. For example, courage is a virtue that lies between
17548-417: The importance of a strong state and strict laws. Buddhism was introduced to China in the 1st century CE and diversified into new forms of Buddhism . Starting in the 3rd century CE, the school of Xuanxue emerged. It interpreted earlier Daoist works with a specific emphasis on metaphysical explanations. Neo-Confucianism developed in the 11th century CE. It systematized previous Confucian teachings and sought
17712-418: The indigenous Shinto religion and Chinese and Indian thought in the forms of Confucianism and Buddhism, both of which entered Japan in the 6th and 7th centuries. Its practice is characterized by active interaction with reality rather than disengaged examination. Neo-Confucianism became an influential school of thought in the 16th century and the following Edo period and prompted a greater focus on language and
17876-411: The intellectual satisfaction of reading a book, are more valuable than lower pleasures, like the sensory enjoyment of food and drink, even if their intensity and duration are the same. Since its original formulation, many variations of utilitarianism have developed, including the difference between act and rule utilitarianism and between maximizing and satisficing utilitarianism. Deontology assesses
18040-480: The interconnectedness of all things. Latin American philosophy during the colonial period , starting around 1550, was dominated by religious philosophy in the form of scholasticism . Influential topics in the post-colonial period were positivism , the philosophy of liberation , and the exploration of identity and culture. Early African philosophy, like Ubuntu philosophy , was focused on community, morality, and ancestral ideas. Systematic African philosophy emerged at
18204-609: The level of ontology , it examines whether there are objective moral facts. Concerning semantics , it asks what the meaning of moral terms are and whether moral statements have a truth value . The epistemological side of metaethics discusses whether and how people can acquire moral knowledge. Metaethics overlaps with psychology because of its interest in how moral judgments motivate people to act. It also overlaps with anthropology since it aims to explain how cross-cultural differences affect moral assessments. Metaethics examines basic ethical concepts and their relations. Ethics
18368-548: The manifestation of cognitive virtues instead of justification; or they deny that knowledge can be analyzed in terms of other phenomena. Another area in epistemology asks how people acquire knowledge. Often-discussed sources of knowledge are perception , introspection , memory , inference , and testimony . According to empiricists , all knowledge is based on some form of experience. Rationalists reject this view and hold that some forms of knowledge, like innate knowledge , are not acquired through experience. The regress problem
18532-496: The modern sense of the term. Influential traditions in the history of philosophy include Western , Arabic–Persian , Indian , and Chinese philosophy . Western philosophy originated in Ancient Greece and covers a wide area of philosophical subfields. A central topic in Arabic–Persian philosophy is the relation between reason and revelation . Indian philosophy combines the spiritual problem of how to reach enlightenment with
18696-569: The moral rightness of actions based on a set of norms or principles. These norms describe the requirements that all actions need to follow. They may include principles like telling the truth, keeping promises , and not intentionally harming others. Unlike consequentialists, deontologists hold that the validity of general moral principles does not directly depend on their consequences. They state that these principles should be followed in every case since they express how actions are inherently right or wrong. According to moral philosopher David Ross , it
18860-477: The moral value of acts only depends on the pleasure and suffering they cause. An alternative approach says that there are many different sources of value, which all contribute to one overall value. Before the 20th century, consequentialists were only concerned with the total of value or the aggregate good. In the 20th century, alternative views were developed that additionally consider the distribution of value. One of them states that an equal distribution of goods
19024-594: The most fundamental level. Another subfield of metaphysics is philosophical cosmology . It is interested in the essence of the world as a whole. It asks questions including whether the universe has a beginning and an end and whether it was created by something else. A key topic in metaphysics concerns the question of whether reality only consists of physical things like matter and energy. Alternative suggestions are that mental entities (such as souls and experiences ) and abstract entities (such as numbers) exist apart from physical things. Another topic in metaphysics concerns
19188-402: The most influential philosophers of the subsequent period. The increasing influence of Western thought and institutions in the 19th and 20th centuries gave rise to the intellectual movement of Islamic modernism , which aims to understand the relation between traditional Islamic beliefs and modernity. One of the distinguishing features of Indian philosophy is that it integrates the exploration of
19352-431: The motives and intentions behind people's actions, highlighting the importance of acting for the right reasons. They tend to be agent-relative, meaning that the reasons for which people should act depend on personal circumstances. For example, a parent has a special obligation to their child, while a stranger does not have this kind of obligation toward a child they do not know. Patient-centered theories, by contrast, focus on
19516-470: The natural and social sciences, religion, and mathematics. Epistemology is the branch of philosophy that studies knowledge. It is also known as theory of knowledge and aims to understand what knowledge is, how it arises, what its limits are, and what value it has. It further examines the nature of truth , belief , justification , and rationality . Some of the questions addressed by epistemologists include "By what method(s) can one acquire knowledge?"; "How
19680-469: The natural flow of the universe . Indigenous belief systems, like Native American philosophy and the African Ubuntu philosophy , often emphasize the interconnectedness of all living beings and the environment while stressing the importance of living in harmony with nature. Metaethics is the branch of ethics that examines the nature, foundations, and scope of moral judgments , concepts, and values. It
19844-501: The natural world. The Kyoto School emerged in the 20th century and integrated Eastern spirituality with Western philosophy in its exploration of concepts like absolute nothingness ( zettai-mu ), place ( basho ), and the self . Latin American philosophy in the pre-colonial period was practiced by indigenous civilizations and explored questions concerning the nature of reality and the role of humans. It has similarities to indigenous North American philosophy , which covered themes such as
20008-454: The nature and sources of morality. It analyzes the meaning of ethical concepts, like right action and obligation . It also investigates whether ethical theories can be true in an absolute sense and how to acquire knowledge of them. Normative ethics encompasses general theories of how to distinguish between right and wrong conduct. It helps guide moral decisions by examining what moral obligations and rights people have. Applied ethics studies
20172-465: The nature of reality, the ways of arriving at knowledge, and the spiritual question of how to reach enlightenment . It started around 900 BCE when the Vedas were written. They are the foundational scriptures of Hinduism and contemplate issues concerning the relation between the self and ultimate reality as well as the question of how souls are reborn based on their past actions . This period also saw
20336-525: The number of female philosophers , but they still remained underrepresented. Arabic–Persian philosophy arose in the early 9th century CE as a response to discussions in the Islamic theological tradition . Its classical period lasted until the 12th century CE and was strongly influenced by ancient Greek philosophers. It employed their ideas to elaborate and interpret the teachings of the Quran . Al-Kindi (801–873 CE)
20500-499: The older dialects, although the Doric dialect has survived in the Tsakonian language , which is spoken in the region of modern Sparta. Doric has also passed down its aorist terminations into most verbs of Demotic Greek . By about the 6th century AD, the Koine had slowly metamorphosed into Medieval Greek . Phrygian is an extinct Indo-European language of West and Central Anatolia , which
20664-430: The people affected by actions and the rights they have. An example is the requirement to treat other people as ends and not merely as a means to an end. This requirement can be used to argue, for example, that it is wrong to kill a person against their will even if this act would save the lives of several others. Patient-centered deontological theories are usually agent-neutral, meaning that they apply equally to everyone in
20828-487: The perfect stem eilēpha (not * lelēpha ) because it was originally slambanō , with perfect seslēpha , becoming eilēpha through compensatory lengthening. Reduplication is also visible in the present tense stems of certain verbs. These stems add a syllable consisting of the root's initial consonant followed by i . A nasal stop appears after the reduplication in some verbs. The earliest extant examples of ancient Greek writing ( c. 1450 BC ) are in
20992-440: The person possesses and exercises certain capacities or some form of control . If a person is morally responsible then it is appropriate to respond to them in certain ways, for example, by praising or blaming them. A major debate in metaethics is about the ontological status of morality, questioning whether ethical values and principles are real. It examines whether moral properties exist as objective features independent of
21156-411: The person would want everyone to follow the same maxim as a universal law applicable to everyone. Another formulation states that one should treat other people always as ends in themselves and never as mere means to an end. This formulation focuses on respecting and valuing other people for their own sake rather than using them in the pursuit of personal goals. In either case, Kant says that what matters
21320-433: The philosophical sense is the field that studies the nature and appreciation of beauty and other aesthetic properties, like the sublime . Although it is often treated together with the philosophy of art , aesthetics is a broader category that encompasses other aspects of experience, such as natural beauty. In a more general sense, aesthetics is "critical reflection on art, culture, and nature ". A key question in aesthetics
21484-471: The practice of selfless love , such as the Great Commandment to "Love your neighbor as yourself". The Five Pillars of Islam constitute a basic framework of Muslim ethics and focus on the practice of faith , prayer , charity , fasting during Ramadan , and pilgrimage to Mecca . Buddhists emphasize the importance of compassion and loving-kindness towards all sentient entities. A similar outlook
21648-415: The precise definition of the term and its meaning has changed throughout the ages. Metaphysicians attempt to answer basic questions including " Why is there something rather than nothing? "; "Of what does reality ultimately consist?"; and "Are humans free?" Metaphysics is sometimes divided into general metaphysics and specific or special metaphysics. General metaphysics investigates being as such. It examines
21812-430: The principles that govern the moral evaluation of conduct , character traits , and institutions . It examines what obligations people have, what behavior is right and wrong, and how to lead a good life. Some of its key questions are "How should one live?" and "What gives meaning to life ?". In contemporary philosophy, ethics is usually divided into normative ethics , applied ethics , and metaethics . Morality
21976-449: The problem of identity . One question is how much an entity can change while still remaining the same entity. According to one view, entities have essential and accidental features . They can change their accidental features but they cease to be the same entity if they lose an essential feature. A central distinction in metaphysics is between particulars and universals . Universals, like the color red, can exist at different locations at
22140-426: The provocative, vexing, and enduring problems central to the human condition. The philosophical pursuit of wisdom involves asking general and fundamental questions. It often does not result in straightforward answers but may help a person to better understand the topic, examine their life, dispel confusion, and overcome prejudices and self-deceptive ideas associated with common sense. For example, Socrates stated that "
22304-434: The rational study of reality, knowledge, and values. It is distinguished from other disciplines of rational inquiry such as the empirical sciences and mathematics . The practice of philosophy is characterized by several general features: it is a form of rational inquiry, it aims to be systematic, and it tends to critically reflect on its own methods and presuppositions. It requires attentively thinking long and carefully about
22468-468: The right to receive that benefit. Obligation and permission are contrasting terms that can be defined through each other: to be obligated to do something means that one is not permitted not to do it and to be permitted to do something means that one is not obligated not to do it. Some theorists define obligations in terms of values or what is good . When used in a general sense, good contrasts with bad . When describing people and their intentions,
22632-417: The same course of action but provide different justifications for why it is right. Consequentialism, also called teleological ethics, says that morality depends on consequences. According to the most common view, an act is right if it brings the best future. This means that there is no alternative course of action that has better consequences. A key aspect of consequentialist theories is that they provide
22796-401: The same ontological status as non-moral facts: it is an objective fact whether there is an obligation to keep a promise just as it is an objective fact whether a thing is rectangular. Moral realism is often associated with the claim that there are universal ethical principles that apply equally to everyone. It implies that if two people disagree about a moral evaluation then at least one of them
22960-486: The same questions. Epistemology, ethics, logic, and metaphysics are sometimes listed as the main branches. There are many other subfields besides them and the different divisions are neither exhaustive nor mutually exclusive. For example, political philosophy, ethics, and aesthetics are sometimes linked under the general heading of value theory as they investigate normative or evaluative aspects. Furthermore, philosophical inquiry sometimes overlaps with other disciplines in
23124-423: The same time required to justify them using rational argumentation. The main concern of virtue ethics is how virtues are expressed in actions. As such, it is neither directly interested in the consequences of actions nor in universal moral duties. Virtues are positive character traits like honesty , courage , kindness , and compassion . They are usually understood as dispositions to feel, decide, and act in
23288-506: The same time. This is not the case for particulars including individual persons or specific objects. Other metaphysical questions are whether the past fully determines the present and what implications this would have for the existence of free will . There are many other subfields of philosophy besides its core branches. Some of the most prominent are aesthetics, philosophy of language, philosophy of mind, philosophy of religion, philosophy of science, and political philosophy. Aesthetics in
23452-407: The same way as the sciences. This problem is avoided by seeing philosophy as an immature or provisional science whose subdisciplines cease to be philosophy once they have fully developed. In this sense, philosophy is sometimes described as "the midwife of the sciences". Other definitions focus on the contrast between science and philosophy. A common theme among many such conceptions is that philosophy
23616-505: The scope and fundamental concepts of these fields. It also investigates their methods and ethical implications. The word philosophy comes from the Ancient Greek words φίλος ( philos ) ' love ' and σοφία ( sophia ) ' wisdom ' . Some sources say that the term was coined by the pre-Socratic philosopher Pythagoras , but this is not certain. The word entered the English language primarily from Old French and Anglo-Norman starting around 1175 CE. The French philosophie
23780-409: The structure of practical reason and are true for all rational agents. According to Kant, to act morally is to act in agreement with reason as expressed by these principles while violating them is both immoral and irrational. Kant provided several formulations of the categorical imperative. One formulation says that a person should only follow maxims that can be universalized . This means that
23944-594: The study of the biggest patterns of the world as a whole or as the attempt to answer the big questions. Such an approach is pursued by Immanuel Kant , who holds that the task of philosophy is united by four questions: "What can I know?"; "What should I do?"; "What may I hope?"; and "What is the human being?" Both approaches have the problem that they are usually either too wide, by including non-philosophical disciplines, or too narrow, by excluding some philosophical sub-disciplines. Many definitions of philosophy emphasize its intimate relation to science. In this sense, philosophy
24108-517: The syllabic script Linear B . Beginning in the 8th century BC, however, the Greek alphabet became standard, albeit with some variation among dialects. Early texts are written in boustrophedon style, but left-to-right became standard during the classic period. Modern editions of ancient Greek texts are usually written with accents and breathing marks , interword spacing , modern punctuation , and sometimes mixed case , but these were all introduced later. The beginning of Homer 's Iliad exemplifies
24272-466: The teachings of Advaita Vedanta to argue that all the different religions are valid paths toward the one divine. Chinese philosophy is particularly interested in practical questions associated with right social conduct, government, and self-cultivation . Many schools of thought emerged in the 6th century BCE in competing attempts to resolve the political turbulence of that period. The most prominent among them were Confucianism and Daoism . Confucianism
24436-544: The teachings of the Quran . Contractualists reject the reference to God as the source of morality and argue instead that morality is based on an explicit or implicit social contract between humans. They state that actual or hypothetical consent to this contract is the source of moral norms and duties. To determine which duties people have, contractualists often rely on a thought experiment about what rational people under ideal circumstances would agree on. For example, if they would agree that people should not lie then there
24600-455: The term evil rather than bad is often employed. Obligations are used to assess the moral status of actions, motives , and character traits . An action is morally right if it is in tune with a person's obligations and morally wrong if it violates them. Supererogation is a special moral status that applies to cases in which the agent does more than is morally required of them. To be morally responsible for an action usually means that
24764-512: The term ethics can also refer to individual ethical theories in the form of a rational system of moral principles, such as Aristotelian ethics , and to a moral code that certain societies, social groups, or professions follow, as in Protestant work ethic and medical ethics . The English word ethics has its roots in the Ancient Greek word êthos ( ἦθος ), meaning ' character ' and ' personal disposition ' . This word gave rise to
24928-463: The time of the Dorian invasions —and that their first appearances as precise alphabetic writing began in the 8th century BC. The invasion would not be "Dorian" unless the invaders had some cultural relationship to the historical Dorians . The invasion is known to have displaced population to the later Attic-Ionic regions, who regarded themselves as descendants of the population displaced by or contending with
25092-402: The two. According to one view, morality focuses on what moral obligations people have while ethics is broader and includes ideas about what is good and how to lead a meaningful life. Another difference is that codes of conduct in specific areas, such as business and environment, are usually termed ethics rather than morality, as in business ethics and environmental ethics . Normative ethics
25256-596: The unexamined life is not worth living " to highlight the role of philosophical inquiry in understanding one's own existence. And according to Bertrand Russell , "the man who has no tincture of philosophy goes through life imprisoned in the prejudices derived from common sense, from the habitual beliefs of his age or his nation, and from convictions which have grown up in his mind without the cooperation or consent of his deliberate reason." Attempts to provide more precise definitions of philosophy are controversial and are studied in metaphilosophy . Some approaches argue that there
25420-399: The value of consequences based on whether they promote happiness or suffering. But there are also alternative evaluative principles, such as desire satisfaction, autonomy , freedom , knowledge , friendship , beauty , and self-perfection. Some forms of consequentialism hold that there is only a single source of value . The most prominent among them is utilitarianism , which states that
25584-475: Was Aeolic. For example, fragments of the works of the poet Sappho from the island of Lesbos are in Aeolian. Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, or to an island. Doric notably had several intermediate divisions as well, into Island Doric (including Cretan Doric ), Southern Peloponnesus Doric (including Laconian ,
