Common sense is "knowledge, judgement, and taste which is more or less universal and which is held more or less without reflection or argument". As such, it is often considered to represent the basic level of sound practical judgement or knowledge of basic facts that any adult human being ought to possess. It is "common" in the sense of being shared by nearly all people. The everyday understanding of common sense is ultimately derived from historical philosophical discussions. Relevant terms from other languages used in such discussions include Latin sensus communis , Ancient Greek κοινὴ αἴσθησις ( koinḕ aísthēsis ), and French bon sens . However, these are not straightforward translations in all contexts, and in English different shades of meaning have developed. In philosophical and scientific contexts, since the Age of Enlightenment the term "common sense" has been used for rhetorical effect both approvingly and disapprovingly. On the one hand it has been a standard for good taste , good sense, and source of scientific and logical axioms . On the other hand it has been equated to conventional wisdom , vulgar prejudice , and superstition .

153-687: Eugen Fink (11 December 1905 – 25 July 1975) was a German philosopher . Fink was born in 1905 as the son of a government official in Germany. He spent his first school years with an uncle who was a Catholic priest. Fink attended a grammar school in Konstanz where he succeeded with his extraordinary memory. After his graduation exam in 1925, he studied philosophy , history , German language and economics , initially at Münster and Berlin and then in Freiburg with Edmund Husserl . As Husserl's assistant from 1928, he

306-425: 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

459-448: A Cartesian-influenced Spanish government, was not widely read until the 20th century, but his writings on common sense have been an important influence upon Hans-Georg Gadamer, Benedetto Croce and Antonio Gramsci . Vico united the Roman and Greek meanings of the term communis sensus . Vico's initial use of the term, which was of much inspiration to Gadamer for example, appears in his On

612-468: A basis for a new and better-founded approach to discuss Natural Law , improving upon Grotius, John Selden , and Pufendorf who he felt had failed to convince, because they could claim no authority from nature. Unlike Grotius, Vico went beyond looking for one single set of similarities amongst nations but also established rules about how natural law properly changes as peoples change, and has to be judged relative to this state of development. He thus developed

765-508: A conceptual way as a capability. Aristotle never fully spells out the relationship between the common sense and the imaginative faculty ( φᾰντᾰσῐ́ᾱ , phantasíā ), although the two clearly work together in animals, and not only humans, for example in order to enable a perception of time. They may even be the same. Despite hints by Aristotle himself that they were united, early commentators such as Alexander of Aphrodisias and Al-Farabi felt they were distinct, but later, Avicenna emphasized

918-480: A detailed view of an evolving wisdom of peoples. Ancient forgotten wisdoms, he claimed, could be re-discovered by analysis of languages and myths formed under the influence of them. This is comparable to both Montesquieu 's Spirit of the Laws , as well as much later Hegelian historicism , both of which apparently developed without any awareness of Vico's work. Contemporary with Hume, but critical of Hume's scepticism,

1071-545: 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

1224-594: A fund of remembered images in their imagination, and then using ingenuity in creating linking metaphors, in order to make enthymemes . Enthymemes are reasonings about uncertain truths and probabilities—as opposed to the Cartesian method, which was skeptical of all that could not be dealt with as syllogisms , including raw perceptions of physical bodies. Hence common sense is not just a "guiding standard of eloquence " but also "the standard of practical judgment ". The imagination or fantasy, which under traditional Aristotelianism

1377-444: 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

1530-441: A highly erudite and influential defense of the use of irony and humour in serious discussions, at least among men of "Good Breeding". He drew upon authors such as Seneca , Juvenal , Horace and Marcus Aurelius , for whom, he saw, common sense was not just a reference to widely held vulgar opinions, but something cultivated among educated people living in better communities. One aspect of this, later taken up by authors such as Kant,

1683-697: 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

1836-663: A modern way, responding to Machiavellianism and Protestantism as part of the Counter-Reformation . Cartesian theory offered a justification for innovative social change achieved through the courts and administration, an ability to adapt the law to changing social conditions by making the basis for legislation "rational" rather than "traditional". So after Descartes, critical attention turned from Aristotle and his theory of perception, and more towards Descartes' own treatment of common good sense, concerning which several 18th-century authors found help in Roman literature. During

1989-427: A more general account of the souls of all animals, not just humans, moved the act of perception out of the rational thinking soul into this sensus communis , which is something like a sense, and something like thinking, but not rational. The passage is difficult to interpret and there is little consensus about the details. Gregorić (2007 , pp. 204–205) has argued that this may be because Aristotle did not use

2142-531: A more profound rupture with Peripatetic thought. He accepted mental representations but [...] "All sense is fancy", as Hobbes famously put it, with the only exception of extension and motion. But Descartes used two different terms in his work, not only the Latin term " sensus communis ", but also the French term bon sens , with which he opens his Discourse on Method . And this second concept survived better. This work

2295-504: A new more peculiarly Roman way, probably also influenced by Greek Stoicism, therefore remains a subject of discussion. Schaeffer (1990 , p. 112) has proposed for example that the Roman republic maintained a very "oral" culture whereas in Aristotle's time rhetoric had come under heavy criticism from philosophers such as Socrates. Peters Agnew (2008) argues, in agreement with Shaftesbury, that

2448-463: A noticeable growth in 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

2601-460: 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

2754-434: A sense — a "common sense" or sense of the common things ( aísthēsis koinḕ ) — and there is no specific ( idéā ) sense perception for movement and other koiná , because then we would not perceive the koiná at all, except by accident ( κᾰτᾰ́ σῠμβεβηκός , katá sumbebēkós ). As examples of perceiving by accident Aristotle mentions using the specific sense perception vision on its own to try to see that something

2907-445: A similar and sufficient amount of common sense ( bon sens ), but it is rarely used well. Therefore, a skeptical logical method described by Descartes needs to be followed and common sense should not be overly relied upon. In the ensuing 18th century Enlightenment , common sense came to be seen more positively as the basis for empiricist modern thinking. It was contrasted to metaphysics , which was, like Cartesianism , associated with

3060-461: A similarity to the assertion of a priori knowledge asserted by rationalists like Descartes and Kant, despite Reid's criticism of Descartes concerning his theory of ideas. Hume was critical of Reid on this point. Despite the criticism, the influence of the Scottish school was notable for example upon American pragmatism , and modern Thomism . The influence has been particularly important concerning

3213-413: A so-called Scottish school of Common Sense formed, whose basic principle was enunciated by its founder and greatest figure, Thomas Reid : If there are certain principles, as I think there are, which the constitution of our nature leads us to believe, and which we are under a necessity to take for granted in the common concerns of life, without being able to give a reason for them — these are what we call

3366-491: A standardization of the term koinḕ aísthēsis as a term for the perceptual capacity (not the higher level sensory capacity), which occurred by the time of Alexander of Aphrodisias at the latest. Compared to Plato, Aristotle's understanding of the soul ( psūkhḗ ) has an extra level of complexity in the form of the noûs or "intellect"—which is something only humans have and enables humans to perceive things differently from other animals. It works with images coming from

3519-731: A technical term limited to discussion about sense perception, as Aristotle apparently had in De Anima , and as the Scholastics later would in the Middle Ages. Instead of referring to all animal judgment, it was used to describe pre-rational, widely shared human beliefs, and therefore it was a near equivalent to the concept of humanitas . This was a term that could be used by Romans to imply not only human nature , but also humane conduct, good breeding, refined manners, and so on. Apart from Cicero, Quintilian , Lucretius , Seneca , Horace and some of

3672-445: A valid answer to the challenge of extreme skepticism . Concerning such sceptics, he wrote: But would these prejudiced reasoners reflect a moment, there are many obvious instances and arguments, sufficient to undeceive them, and make them enlarge their maxims and principles. Do they not see the vast variety of inclinations and pursuits among our species; where each man seems fully satisfied with his own course of life, and would esteem it

3825-612: 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

3978-615: 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 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

4131-489: 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

4284-510: 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

4437-534: 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 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

4590-561: 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

4743-480: Is a term opposed to specific or particular ( idia ). The Greek for these common sensibles is tá koiná ( τά κοινᾰ́ ), which means shared or common things, and examples include the oneness of each thing, with its specific shape and size and so on, and the change or movement of each thing. Distinct combinations of these properties are common to all perceived things. In this passage, Aristotle explained that concerning these koiná (such as movement) people have

4896-467: 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

5049-479: 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

5202-666: Is and how to acquire it. Ethics investigates moral principles and what constitutes right conduct. Logic 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

5355-451: 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

5508-408: 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

5661-455: Is everywhere met with, the possession of which indicates absolutely no merit or superiority. But under the sensus communis we must include the Idea of a communal sense [ eines gemeinschaftlichen Sinnes ], i.e. of a faculty of judgement, which in its reflection takes account ( a priori ) of the mode of representation of all other men in thought; in order as it were to compare its judgement with

5814-408: Is itself a borrowing from the Latin philosophia . 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

5967-475: 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

6120-418: 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

Common sense "Common sense" has at least two older and more specialized meanings which have influenced the modern meanings, and are still important in philosophy . The original historical meaning is the capability of the animal soul ( ψῡχή , psūkhḗ ), proposed by Aristotle to explain how

Lee (2011 , p. 31) explains that "when I see Socrates, it is not insofar as he is Socrates that he is visible to my eye, but rather because he is coloured". So the normal five individual senses do sense the common perceptibles according to Aristotle (and Plato), but it is not something they necessarily interpret correctly on their own. Aristotle proposes that

6579-439: 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

6732-468: 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

6885-457: Is the source of the most common meaning of common sense today: practical judgment". Gilson noted that Descartes actually gave bon sens two related meanings, first the basic and widely shared ability to judge true and false, which he also calls raison ( lit.   ' 'reason' ' ); and second, wisdom, the perfected version of the first. The Latin term Descartes uses, bona mens ( lit.   ' 'good mind' ' ), derives from

7038-462: Is truth established?"; and "Can we prove causal relations?" 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

7191-500: Is used. For example, French sens commun and German Gemeinsinn are used for this feeling of human solidarity, while bon sens (good sense) and gesunder Verstand (healthy understanding) are the terms for everyday "common sense". According to Gadamer, at least in French and British philosophy a moral element in appeals to common sense (or bon sens ), such as found in Reid, remains normal to this day. But according to Gadamer,

7344-456: Is usually divided into formal and informal logic . Formal logic uses artificial languages with a precise symbolic representation to investigate arguments. 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

7497-470: Is where this comparison happens, and this must occur by comparing impressions (or symbols or markers; σημεῖον , sēmeîon , 'sign, mark') of what the specialist senses have perceived. The common sense is therefore also where a type of consciousness originates, "for it makes us aware of having sensations at all". And it receives physical picture imprints from the imaginative faculty, which are then memories that can be recollected. The discussion

7650-556: Is whether beauty is an objective feature of entities or a subjective aspect of experience. Aesthetic philosophers also investigate the nature of aesthetic experiences and judgments . 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

7803-516: The Ancien Régime . Thomas Paine 's polemical pamphlet Common Sense (1776) has been described as the most influential political pamphlet of the 18th century, affecting both the American and French revolutions . Today, the concept of common sense, and how it should best be used, remains linked to many of the most perennial topics in epistemology and ethics , with special focus often directed at

(According to Gregorić, this is specifically in contexts where it refers to the higher order common sense that includes imagination.) Later philosophers developing this line of thought, such as Themistius , Galen , and Al-Farabi, calling it the ruler of

Cartesians such as Henricus Regius , Geraud de Cordemoy , and Nicolas Malebranche realized that Descartes's logic could give no evidence of the "external world" at all, meaning it had to be taken on faith. Though his own proposed solution was even more controversial, Berkeley famously wrote that enlightenment requires a "revolt from metaphysical notions to

8262-501: The sense of community that the Romans understood as part of common sense. Another connected epistemological concern was that by considering common good sense as inherently inferior to Cartesian conclusions developed from simple assumptions, an important type of wisdom was being arrogantly ignored.

8415-612: The Enlightenment , Descartes' insistence upon a mathematical-style method of thinking that treated common sense and the sense perceptions sceptically, was accepted in some ways, but also criticized. On the one hand, the approach of Descartes is and was seen as radically sceptical in some ways. On the other hand, like the Scholastics before him, while being cautious of common sense, Descartes was instead seen to rely too much on undemonstrable metaphysical assumptions in order to justify his method, especially in its separation of mind and body (with

8568-523: The Quran . Al-Kindi (801–873 CE) is usually regarded as the first philosopher of this tradition. 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. Al-Ghazali (1058–1111 CE)

8721-562: The Scholastics . But he distanced himself from the Aristotelian conception of a common sense faculty, abandoning it entirely by the time of his Passions of the Soul (1649). Contemporaries such as Gassendi and Hobbes went beyond Descartes in some ways in their rejection of Aristotelianism, rejecting explanations involving anything other than matter and motion, including the distinction between

8874-435: The "father" of the scientific method " to a French audience, an understanding that was widespread by 1750. Together with this, references to "common sense" became positive and associated with modernity, in contrast to negative references to metaphysics, which was associated with the Ancien Régime . As mentioned above, in terms of the more general epistemological implications of common sense, modern philosophy came to use

9027-420: The "things themselves", that is, as originally given in experience. 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

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

Gadamer notes one less-known exception—the Württemberg pietism , inspired by the 18th century Swabian churchman, M. Friedrich Christoph Oetinger , who appealed to Enlightenment figures in his critique of the Cartesian rationalism of Leibniz and Wolff , who were the most important German philosophers before Kant.

A reaction to Shaftesbury in defense of the Hobbesian approach of treating communities as driven by individual self-interest, was not long coming in Bernard Mandeville 's controversial works. Indeed, this approach was never fully rejected, at least in economics. And so despite

This understanding of a moral sense or public spirit remains a subject for discussion, although the term "common sense" is no longer commonly used for the sentiment itself. In several European languages, a separate term for this type of common sense

It presents common sense as something adolescents need to be trained in if they are not to "break into odd and arrogant behaviour when adulthood is reached", whereas teaching Cartesian method on its own harms common sense and stunts intellectual development.

According to Hobbes [...] man is no different from the other animals. [...] Hobbes' philosophy constituted

This began with Descartes 's criticism of it, and what came to be known as the dispute between " rationalism " and " empiricism ". In the opening line of one of his most famous books, Discourse on Method , Descartes established the most common modern meaning, and its controversies, when he stated that everyone has

10557-442: 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

It discusses topics such as ethnophilosophy , négritude , pan-Africanism , Marxism, postcolonialism , the role of cultural identity, relativism , African epistemology , and the critique of Eurocentrism .

Other metaphysical questions are whether the past fully determines the present and what implications this would have for the existence of free will .

Some of the most prominent are aesthetics, philosophy of language, philosophy of mind, philosophy of religion, philosophy of science, and political philosophy. Aesthetics in

11322-729: The common sense and imagination, using reasoning ( λόγος , lógos ) as well as the active intellect . The noûs identifies the true forms of things , while the common sense identifies shared aspects of things. Though scholars have varying interpretations of the details, Aristotle's "common sense" was in any case not rational, in the sense that it implied no ability to explain the perception. Reason or rationality ( lógos ) exists only in man according to Aristotle, and yet some animals can perceive "common perceptibles" such as change and shape, and some even have imagination according to Aristotle. Animals with imagination come closest to having something like reasoning and noûs . Plato, on

11475-566: The common sense was understood to be seated not in the heart, as Aristotle had thought, but in the anterior Galenic ventricle of the brain. The anatomist Andreas Vesalius found no connections between the anterior ventricle and the sensory nerves, leading to speculation about other parts of the brain into the 1600s. " Sensus communis " is the Latin translation of the Greek koinḕ aísthēsis , which came to be recovered by Medieval scholastics when discussing Aristotelian theories of perception. In

11628-508: The common sense, imagination , vis cogitativa , and memory. Avicenna, followed by Robert Grosseteste , Albert the Great , and Roger Bacon , argued for five internal senses: the common sense, imagination, fantasy, vis aestimativa , and memory." By the time of Descartes and Hobbes , in the 1600s, the inner senses had been standardized to five wits , which complemented the more well-known five "external" senses. Under this medieval scheme

11781-648: The communal common sense described by Shaftesbury and Hutcheson, and the perceptive powers described by Aristotelians. Reid was criticised, partly for his critique of Hume, by Kant and J. S. Mill , who were two of the most important influences in nineteenth century philosophy. He was blamed for over-stating Hume's scepticism of commonly held beliefs, and more importantly for not perceiving the problem with any claim that common sense could ever fulfill Cartesian (or Kantian) demands for absolute knowledge. Reid furthermore emphasized inborn common sense as opposed to only experience and sense perception. In this way his common sense has

11934-426: The concept developed from the Stoic concept of ethical virtue, influenced by Aristotle, but emphasizing the role of both the individual perception, and shared communal understanding. But in any case a complex of ideas attached itself to the term, to be almost forgotten in the Middle Ages, and eventually returning into ethical discussion in 18th-century Europe, after Descartes. As with other meanings of common sense, for

12087-461: 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

12240-614: 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

12393-489: The criticism heaped upon Mandeville and Hobbes by Adam Smith, Hutcheson's student and successor in Glasgow university, Smith made self-interest a core assumption within nascent modern economics, specifically as part of the practical justification for allowing free markets. By the late enlightenment period in the 18th century, the communal sense had become the "moral sense" or " moral sentiment " referred to by Hume and Adam Smith ,

12546-420: The different senses join and enable discrimination of particular objects by people and other animals. This common sense is distinct from the several sensory perceptions and from human rational thought , but it cooperates with both. The second philosophical use of the term is Roman-influenced, and is used for the natural human sensitivity for other humans and the community. Just like the everyday meaning, both of

12699-642: The earlier Latin of the Roman empire, the term had taken a distinct ethical detour, developing new shades of meaning. These especially Roman meanings were apparently influenced by several Stoic Greek terms with the word koinḗ ( κοινή , 'common, shared'); not only koinḕ aísthēsis , but also such terms as koinós noûs ( κοινός νοῦς , 'common mind/thought/reason'), koinḗ énnoia ( κοινή ἔννοιᾰ ), and koinonoēmosúnē , all of which involve noûs —something, at least in Aristotle, that would not be present in "lower" animals. Another link between Latin communis sensus and Aristotle's Greek

12852-400: 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

13005-478: 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

13158-420: The entire human race". Vico proposed his own anti-Cartesian methodology for a new Baconian science, inspired, he said, by Plato , Tacitus , Francis Bacon and Grotius . In this he went further than his predecessors concerning the ancient certainties available within vulgar common sense. What is required, according to his new science, is to find the common sense shared by different people and nations. He made this

13311-474: The epistemological importance of a sensus communis for any possibility of rational discussion between people. Immanuel Kant developed a new variant of the idea of sensus communis , noting how having a sensitivity for what opinions are widely shared and comprehensible gives a sort of standard for judgment, and objective discussion, at least in the field of aesthetics and taste: The common Understanding of men [ gemeine Menschenverstand ], which, as

13464-527: The existence of innate or " a priori " knowledge in the human mind—a controversial proposal. In contrast to the rationalists, the " empiricists " took their orientation from Francis Bacon , whose arguments for methodical science were earlier than those of Descartes, and less directed towards mathematics and certainty. Bacon is known for his doctrine of the " idols of the mind ", presented in his Novum Organum , and in his Essays described normal human thinking as biased towards believing in lies. But he

13617-407: 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

13770-407: The first Baconian analysis of man (something the lesser known Vico had claimed earlier), common sense is entirely built up from shared experience and shared innate emotions, and therefore it is indeed imperfect as a basis for any attempt to know the truth or to make the best decision. But he defended the possibility of science without absolute certainty, and consistently described common sense as giving

13923-468: The first being found in animals and the second unique to humans and involving reason. Therefore, in Aristotle (and the medieval Aristotelians) the universals used to identify and categorize things are divided into two. In medieval terminology these are the species sensibilis used for perception and imagination in animals, and the species intelligibilis or apprehendable forms used in the human intellect or noûs . Aristotle also occasionally called

14076-450: The five senses perceives one type of "perceptible" or "sensible" which is specific ( ἴδια , idia ) to it. For example, sight can see colour. But Aristotle was explaining how the animal mind, not just the human mind, links and categorizes different tastes, colours, feelings, smells and sounds in order to perceive real things in terms of the "common sensibles" (or "common perceptibles"). In this discussion, "common" ( κοινή , koiné )

14229-624: The greatest unhappiness to be confined to that of his neighbour? Do they not feel in themselves, that what pleases at one time, displeases at another, by the change of inclination; and that it is not in their power, by their utmost efforts, to recall that taste or appetite, which formerly bestowed charms on what now appears indifferent or disagreeable? [...] Do you come to a philosopher as to a cunning man, to learn something by magic or witchcraft, beyond what can be known by common prudence and discretion? Once Thomas Hobbes and Spinoza had applied Cartesian approaches to political philosophy , concerns about

14382-422: The heart, by the time of Descartes this faculty was thought to be in the brain, and he located it in the pineal gland . Descartes' judgement of this common sense was that it was enough to persuade the human consciousness of the existence of physical things, but often in a very indistinct way. To get a more distinct understanding of things, it is more important to be methodical and mathematical. This line of thought

14535-471: 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

14688-420: 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

14841-419: 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

14994-541: The inhumanity of the deductive approach of Descartes increased. With this in mind, Shaftesbury and Giambattista Vico presented new arguments for the importance of the Roman understanding of common sense, in what is now often referred to, after Hans-Georg Gadamer , as a humanist interpretation of the term. Their concern had several inter-related aspects. One ethical concern was the deliberately simplified method that treated human communities as made up of selfish independent individuals ( methodological individualism ), ignoring

15147-483: 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

15300-485: The latter writing in plural of the "moral sentiments" with the key one being sympathy , which was not so much a public spirit as such, but a kind of extension of self-interest. Jeremy Bentham gives a summary of the plethora of terms used in British philosophy by the nineteenth century to describe common sense in discussions about ethics: Another man comes and alters the phrase: leaving out moral, and putting in common , in

15453-448: The link, influencing future authors including Christian philosophers. Gregorić (2007 , p. 205) argues that Aristotle used the term "common sense" both to discuss the individual senses when these act as a unity, which Gregorić calls "the perceptual capacity of the soul", or the higher level "sensory capacity of the soul" that represents the senses and the imagination working as a unity. According to Gregorić, there appears to have been

15606-400: The lowest level it means tact. In Horace the man who talks to you when you obviously don't want to talk lacks communis sensus . Compared to Aristotle and his strictest medieval followers, these Roman authors were not so strict about the boundary between animal-like common sense and specially human reasoning. As discussed above, Aristotle had attempted to make a clear distinction between, on

15759-551: 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

15912-454: The meanings has come to be particularly notable in English, as opposed to other western European languages, and the English term has in turn become international. It was at the beginning of the 18th century that this old philosophical term first acquired its modern English meaning: "Those plain, self-evident truths or conventional wisdom that one needed no sophistication to grasp and no proof to accept precisely because they accorded so well with

16065-431: The mere sound (not yet cultivated) Understanding, we regard as the least to be expected from any one claiming the name of man, has therefore the doubtful honour of being given the name of common sense [ Namen des Gemeinsinnes ] ( sensus communis ); and in such a way that by the name common (not merely in our language, where the word actually has a double signification, but in many others) we understand vulgar, that which

16218-596: 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

16371-418: The most influential Roman authors influenced by Aristotle's rhetoric and philosophy used the Latin term " sensus communis " in a range of such ways. As C. S. Lewis wrote: Quintilian says it is better to send a boy to school than to have a private tutor for him at home; for if he is kept away from the herd ( congressus ) how will he ever learn that sensus which we call communis ? (I, ii, 20). On

16524-404: 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

16677-439: The multitude". In a similar passage in his own work on rhetoric, De Oratore , Cicero wrote that "in oratory the very cardinal sin is to depart from the language of everyday life and the usage approved by the sense of the community." The sense of the community is in this case one translation of " communis sensus " in the Latin of Cicero. Whether the Latin writers such as Cicero deliberately used this Aristotelian term in

16830-472: 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

16983-504: 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

17136-455: 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

17289-467: 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

17442-468: The one hand, imagination and the sense perception which both use the sensible koiná , and which animals also have; and, on the other hand, noûs (intellect) and reason, which perceives another type of koiná , the intelligible forms, which (according to Aristotle) only humans have. In other words, these Romans allowed that people could have animal-like shared understandings of reality, not just in terms of memories of sense perceptions, but in terms of

17595-458: The other hand was apparently willing to allow that animals could have some level of thought, meaning that he did not have to explain their sometimes complex behavior with a strict division between high-level perception processing and the human-like thinking such as being able to form opinions. Gregorić additionally argues that Aristotle can be interpreted as using the verbs phroneîn and noeîn to distinguish two types of thinking or awareness,

17748-451: The philosophical meanings refer to a type of basic awareness and ability to judge that most people are expected to share naturally, even if they cannot explain why. All these meanings of "common sense", including the everyday ones, are interconnected in a complex history and have evolved during important political and philosophical debates in modern Western civilisation , notably concerning science, politics and economics. The interplay between

17901-483: The philosophical problems pre-questions, that are never ready-made problems with predetermined factors such as in natural sciences but have to be created in a genuine act of philosophical reflexion. Philosopher 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

18054-436: 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

18207-478: The philosophy of the modern social sciences . The origin of the term "common sense" is in the works of Aristotle. Heller-Roazen (2008) writes that "In different ways the philosophers of medieval Latin and Arabic tradition, from Al-Farabi to Avicenna , Averroës , Albert , and Thomas , found in the De Anima and the Parva Naturalia the scattered elements of a coherent doctrine of the "central" faculty of

18360-428: The plain dictates of nature and common sense". Descartes and the Cartesian " rationalists ", rejected reliance upon experience, the senses and inductive reasoning , and seemed to insist that certainty was possible. The alternative to induction, deductive reasoning, demanded a mathematical approach, starting from simple and certain assumptions. This in turn required Descartes (and later rationalists such as Kant) to assume

18513-417: 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

18666-454: The principles of common sense; and what is manifestly contrary to them, is what we call absurd. Thomas Reid was a successor to Francis Hutcheson and Adam Smith as Professor of Moral Philosophy, Glasgow . While Reid's interests lay in the defense of common sense as a type of self-evident knowledge available to individuals, this was also part of a defense of natural law in the style of Grotius. He believed his use of "common sense" encompassed both

18819-400: 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

18972-428: 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 "

19125-436: 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

19278-420: The reason for having several senses is in fact that it increases the chances that we can distinguish and recognize things correctly, and not just occasionally or by accident. Each sense is used to identify distinctions, such as sight identifying the difference between black and white, but, says Aristotle, all animals with perception must have "some one thing" that can distinguish black from sweet. The common sense

19431-400: The room of it. He then tells you, that his common sense teaches him what is right and wrong, as surely as the other's moral sense did: meaning by common sense, a sense of some kind or other, which he says, is possessed by all mankind: the sense of those, whose sense is not the same as the author's, being struck out of the account as not worth taking. This was at least to some extent opposed to

19584-488: 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

19737-410: 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

19890-508: 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

20043-559: The senses or ruling sense, apparently a metaphor developed from a section of Plato's Timaeus (70b). Augustine and some of the Arab writers, also called it the "inner sense". The concept of the inner senses, plural, was further developed in the Middle Ages . Under the influence of the great Persian philosophers Al-Farabi and Avicenna, several inner senses came to be listed. "Thomas Aquinas and John of Jandun recognized four internal senses:

20196-452: The sensuous soul." It was "one of the most successful and resilient of Aristotelian notions". The best-known case is De Anima Book III, chapter 1 , especially at line 425a27. The passage is about how the animal mind converts raw sense perceptions from the five specialized sense perceptions , into perceptions of real things moving and changing, which can be thought about. According to Aristotle's understanding of perception, each of

20349-598: 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

20502-469: 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

20655-421: The term as a standardized technical term at all. For example, in some passages in his works, Aristotle seems to use the term to refer to the individual sense perceptions simply being common to all people, or common to various types of animals. There is also difficulty with trying to determine whether the common sense is truly separable from the individual sense perceptions and from imagination, in anything other than

20808-424: The term common sense like Descartes, abandoning Aristotle's theory. While Descartes had distanced himself from it, John Locke abandoned it more openly, while still maintaining the idea of "common sensibles" that are perceived. But then George Berkeley abandoned both. David Hume agreed with Berkeley on this, and like Locke and Vico saw himself as following Bacon more than Descartes. In his synthesis, which he saw as

20961-601: 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

21114-514: The way they would tend to explain things, and in the language they use. One of the last notable philosophers to accept something like the Aristotelian "common sense" was Descartes in the 17th century, but he also undermined it. He described this inner faculty when writing in Latin in his Meditations on first philosophy . The common sense is the link between the body and its senses, and the true human mind, which according to Descartes must be purely immaterial. Unlike Aristotle, who had placed it in

21267-471: Was a representative of Phenomenology (philosophy) and at the same time he became familiar with the philosophy of Martin Heidegger . From early on, Fink was critical recipient of their positions, thereby developing his own approach as a philosophical "cosmology". He approached the problem of Being as a manifestation of the cosmic movement of worldliness with man being a participant in this movement. Fink called

21420-468: Was a strong critic of the idea that reason can arrive at a true understanding of reality and God. He formulated a detailed critique of philosophy and tried to assign philosophy a more limited place besides the teachings of the Quran and mystical insight. Following Al-Ghazali and the end of the classical period, the influence of philosophical inquiry waned. Mulla Sadra (1571–1636 CE) is often regarded as one of

21573-472: Was aimed at certainty, and not mere probability. It was promoted further by people such as Hobbes, Spinoza , and others and continues to have important impacts on everyday life. In France, the Netherlands, Belgium, Spain and Italy, it was in its initial florescence associated with the administration of Catholic empires of the competing Bourbon , and Habsburg dynasties, both seeking to centralize their power in

21726-535: Was also the opponent of all metaphysical explanations of nature, or over-reaching speculation generally, and a proponent of science based on small steps of experience, experimentation and methodical induction. So while agreeing upon the need to help common sense with a methodical approach, he also insisted that starting from common sense, including especially common sense perceptions, was acceptable and correct. He influenced Locke and Pierre Bayle , in their critique of metaphysics, and in 1733 Voltaire "introduced him as

21879-494: Was apparently intended to improve upon the account of Aristotle's friend and teacher Plato in his Socratic dialogue , the Theaetetus . But Plato's dialogue presented an argument that recognising koiná is an active thinking process in the rational part of the human soul, making the senses instruments of the thinking part of man. Plato's Socrates says this kind of thinking is not a kind of sense at all. Aristotle, trying to give

22032-437: Was characterized by the emergence of the six orthodox schools of Hinduism : Nyāyá , Vaiśeṣika , Sāṃkhya , Yoga , Mīmāṃsā , and Vedanta . The school of Advaita Vedanta developed later in this period. It was systematized by Adi Shankara ( c.  700 –750 CE), who held that everything is one and that the impression of a universe consisting of many distinct entities is an illusion . A slightly different perspective

22185-656: Was defended by Ramanuja (1017–1137 CE), who founded the school of Vishishtadvaita Vedanta and argued that individual entities are real as aspects or parts of the underlying unity. He also helped to popularize the Bhakti movement , which taught devotion toward the divine as a spiritual path and lasted until the 17th to 18th centuries CE. The modern period began roughly 1800 CE and was shaped by encounters with Western thought. Philosophers tried to formulate comprehensive systems to harmonize diverse philosophical and religious teachings. For example, Swami Vivekananda (1863–1902 CE) used

22338-508: Was founded by Confucius (551–479 BCE). It focused on different forms of moral virtues and explored how they lead to harmony in society. Daoism was founded by Laozi (6th century BCE) and examined how humans can live in harmony with nature by following the Dao or the natural order of the universe. Other influential early schools of thought were Mohism , which developed an early form of altruistic consequentialism , and Legalism , which emphasized

22491-798: Was good taste. Another very important aspect of common sense particularly interesting to later British political philosophers such as Francis Hutcheson was what came to be called moral sentiment , which is different from a tribal or factional sentiment, but a more general fellow feeling that is very important for larger communities: A publick Spirit can come only from a social Feeling or Sense of Partnership with Human Kind. Now there are none so far from being Partners in this Sense , or sharers in this common Affection , as they who scarcely know an Equall , nor consider themselves as subject to any law of Fellowship or Community . And thus Morality and good Government go together. Hutcheson described it as, "a Publick Sense, viz. "our Determination to be pleased with

22644-450: Was how philosophical and scientific knowledge are created. Specific importance was given to the role of reason and sensory experience . Many of these innovations were used in the Enlightenment movement to challenge traditional authorities. Several attempts to develop comprehensive systems of philosophy were made in the 19th century, for instance, by German idealism and Marxism . Influential developments in 20th-century philosophy were

22797-662: Was in rhetoric , a subject that Aristotle was the first to systematize. In rhetoric, a prudent speaker must take account of opinions ( δόξαι , dóxai ) that are widely held. Aristotle referred to such commonly held beliefs not as koinaí dóxai ( κοιναί δόξαι , lit.   ' 'common opinions' ' ), which is a term he used for self-evident logical axioms, but with other terms such as éndóxa ( ἔνδόξα ). In his Rhetoric for example Aristotle mentions " koinōn [...] tàs písteis " or "common beliefs", saying that "our proofs and arguments must rest on generally accepted principles, [...] when speaking of converse with
