124-429: Isocrates ( / aɪ ˈ s ɒ k r ə t iː z / ; Ancient Greek : Ἰσοκράτης [isokrátɛ̂ːs] ; 436–338 BC) was an ancient Greek rhetorician , one of the ten Attic orators . Among the most influential Greek rhetoricians of his time, Isocrates made many contributions to rhetoric and education through his teaching and written works. Greek rhetoric is commonly traced to Corax of Syracuse , who first formulated

248-537: 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

372-508: A relation between a knower and a known proposition , in the case above between the person Ravi and the proposition "kangaroos hop". It is use-independent since it is not tied to one specific purpose. It is a mental representation that relies on concepts and ideas to depict reality. Because of its theoretical nature, it is often held that only relatively sophisticated creatures, such as humans, possess propositional knowledge. Propositional knowledge contrasts with non-propositional knowledge in

496-412: A series of thought experiments that aimed to show that some justified true beliefs do not amount to knowledge. In one of them, a person is unaware of all the fake barns in their area. By coincidence, they stop in front of the only real barn and form a justified true belief that it is a real barn. Many epistemologists agree that this is not knowledge because the justification is not directly relevant to

620-613: A 1990's excavation at Kellis , a site in the Dakhla Oasis of Egypt . We have nine letters in his name, but the authenticity of four of those has been questioned. He is said to have compiled a treatise, the Art of Rhetoric, but there is no known copy. Other surviving works include his autobiographical Antidosis , and educational texts such as Against the Sophists . Isocrates wrote a collection of ten known orations, three of which were directed to

744-442: A belief is information that favors or supports it. Epistemologists understand evidence primarily in terms of mental states, for example, as sensory impressions or as other propositions that a person knows. But in a wider sense, it can also include physical objects, like bloodstains examined by forensic analysts or financial records studied by investigative journalists. Evidence is often understood in terms of probability : evidence for

868-634: A belief is justified if it coheres with other beliefs. Foundationalists , by contrast, maintain that the justification of basic beliefs does not depend on other beliefs. Internalism and externalism disagree about whether justification is determined solely by mental states or also by external circumstances. Separate branches of epistemology are dedicated to knowledge found in specific fields, like scientific, mathematical, moral, and religious knowledge. Naturalized epistemology relies on empirical methods and discoveries, whereas formal epistemology uses formal tools from logic . Social epistemology investigates

992-473: A belief is justified if the individual's evidence supports the belief and they hold the belief on the basis of this evidence. Reliabilism is an externalist theory asserting that a reliable connection between belief and truth is required for justification. Some reliabilists explain this in terms of reliable processes. According to this view, a belief is justified if it is produced by a reliable belief-formation process, like perception. A belief-formation process

1116-612: A belief makes it more likely that the belief is true. A defeater is evidence against a belief or evidence that undermines another piece of evidence. For instance, witness testimony connecting a suspect to a crime is evidence for their guilt while an alibi is a defeater. Evidentialists analyze justification in terms of evidence by saying that to be justified, a belief needs to rest on adequate evidence. The presence of evidence usually affects doubt and certainty , which are subjective attitudes toward propositions that differ regarding their level of confidence. Doubt involves questioning

1240-592: A belief, known as propositional justification , but also in whether the person holds the belief because or based on this reason, known as doxastic justification . For example, if a person has sufficient reason to believe that a neighborhood is dangerous but forms this belief based on superstition then they have propositional justification but lack doxastic justification. Sources of justification are ways or cognitive capacities through which people acquire justification. Often-discussed sources include perception , introspection , memory , reason , and testimony , but there

1364-414: A common view, this means that the person has sufficient reasons for holding this belief because they have information that supports it. Another view states that a belief is justified if it is formed by a reliable belief formation process, such as perception. The terms reasonable , warranted , and supported are closely related to the idea of justification and are sometimes used as synonyms. Justification

1488-573: A disease helps a doctor cure their patient, and knowledge of when a job interview starts helps a candidate arrive on time. The usefulness of a known fact depends on the circumstances. Knowledge of some facts may have little to no uses, like memorizing random phone numbers from an outdated phone book. Being able to assess the value of knowledge matters in choosing what information to acquire and transmit to others. It affects decisions like which subjects to teach at school and how to allocate funds to research projects. Of particular interest to epistemologists

1612-415: A first-rate education. "He is reported to have studied with several prominent teachers, including Tisias (one of the traditional founders of rhetoric), the sophists Prodicus and Gorgias , and the moderate oligarch Theramenes , and to have associated with Socrates , but these reports may reflect later views of his intellectual roots more than historical fact". He passed his youth in a period following

1736-472: A lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between 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

1860-419: A lesser degree. Pamphylian Greek , spoken in a small area on the southwestern coast of Anatolia and little preserved in inscriptions, may be either 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

1984-452: A letter, a newspaper, and a blog. Rationality is closely related to justification and the terms rational belief and justified belief are sometimes used as synonyms. However, rationality has a wider scope that encompasses both a theoretical side, covering beliefs, and a practical side, covering decisions , intentions , and actions . There are different conceptions about what it means for something to be rational. According to one view,

2108-416: A mental state is rational if it is based on or responsive to good reasons. Another view emphasizes the role of coherence, stating that rationality requires that the different mental states of a person are consistent and support each other. A slightly different approach holds that rationality is about achieving certain goals. Two goals of theoretical rationality are accuracy and comprehensiveness, meaning that

2232-410: A person already has, asserting that a person should only change their beliefs if they have a good reason to. One motivation for adopting epistemic conservatism is that the cognitive resources of humans are limited, meaning that it is not feasible to constantly reexamine every belief. Pragmatist epistemology is a form of fallibilism that emphasizes the close relation between knowing and acting. It sees

2356-744: A person has as few false beliefs and as many true beliefs as possible. Epistemic norms are criteria to assess the cognitive quality of beliefs, like their justification and rationality. Epistemologists distinguish between deontic norms, which are prescriptions about what people should believe or which beliefs are correct, and axiological norms, which identify the goals and values of beliefs. Epistemic norms are closely related to intellectual or epistemic virtues , which are character traits like open-mindedness and conscientiousness . Epistemic virtues help individuals form true beliefs and acquire knowledge. They contrast with epistemic vices and act as foundational concepts of virtue epistemology . Evidence for

2480-419: A person knows depends on the subjective criteria or social conventions used to assess epistemic status. The debate between empiricism and rationalism centers on the origins of human knowledge. Empiricism emphasizes that sense experience is the primary source of all knowledge. Some empiricists express this view by stating that the mind is a blank slate that only develops ideas about the external world through

2604-507: A posteriori knowledge. A priori knowledge is knowledge of non-empirical facts and does not depend on evidence from sensory experience. It belongs to fields such as mathematics and logic , like knowing that 2 + 2 = 4 {\displaystyle 2+2=4} . The contrast between a posteriori and a priori knowledge plays a central role in the debate between empiricists and rationalists on whether all knowledge depends on sensory experience. A closely related contrast

2728-543: 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

2852-671: A separate historical stage, though its earliest form closely resembles Attic Greek , and its latest form approaches Medieval Greek , and Koine may be classified as Ancient Greek in a wider sense. There were several regional dialects of Ancient Greek; Attic Greek developed into Koine. Ancient Greek was a pluricentric language , divided into many dialects. The main dialect groups are Attic and Ionic , Aeolic , Arcadocypriot , and Doric , many of them with several subdivisions. Some dialects are found in standardized literary forms in literature , while others are attested only in inscriptions. There are also several historical forms. Homeric Greek

2976-425: A set of rhetorical rules in the fifth century BC. His pupil Tisias was influential in the development of the rhetoric of the courtroom , and by some accounts was the teacher of Isocrates. Within two generations, rhetoric had become an important art, its growth driven by social and political changes such as democracy and courts of law. Isocrates starved himself to death, two years before his 100th birthday. Isocrates

3100-609: A standard subject of study in educational institutions of the Western world since the Renaissance . This article primarily contains information about the Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period ( c.  300 BC ), Ancient Greek was followed by Koine Greek , which is regarded as

3224-571: A time. Many of them went on to be prominent philosophers, legislators, historians, orators, writers, and military and political leaders. The first students in Isocrates' school were Athenians. However, after he published the Panegyricus in 380 BC, his reputation spread to many other parts of Greece . Some of his students included Isaeus , Lycurgus , Hypereides , Ephorus , Theopompus , Speusippus , and Timotheus . Many of these students remained under

3348-412: A true or a false proposition. According to the correspondence theory of truth , to be true means to stand in the right relation to the world by accurately describing what it is like. This means that truth is objective: a belief is true if it corresponds to a fact . The coherence theory of truth says that a belief is true if it belongs to a coherent system of beliefs. A result of this view is that truth

3472-510: 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

3596-402: Is and what types of knowledge there are. It further investigates the sources of knowledge, like perception , inference , and testimony , to determine how knowledge is created. Another topic is the extent and limits of knowledge, confronting questions about what people can and cannot know. Other central concepts include belief , truth , justification , evidence , and reason . Epistemology

3720-408: Is a closely related process focused not on external physical objects but on internal mental states . For example, seeing a bus at a bus station belongs to perception while feeling tired belongs to introspection. Rationalists understand reason as a source of justification for non-empirical facts. It is often used to explain how people can know about mathematical, logical, and conceptual truths. Reason

3844-409: Is a comparative term, meaning that to know something involves distinguishing it from relevant alternatives. For example, if a person spots a bird in the garden, they may know that it is a sparrow rather than an eagle but they may not know that it is a sparrow rather than an indistinguishable sparrow hologram. Epistemic conservatism is a view about belief revision . It gives preference to the beliefs

3968-556: Is a literary form of Archaic Greek (derived primarily from Ionic and Aeolic) used in the epic poems , the Iliad and the Odyssey , and in later poems by other authors. Homeric Greek had significant differences in grammar and pronunciation from Classical Attic and other Classical-era dialects. The origins, early form and development of the Hellenic language family are not well understood because of

4092-521: Is a special epistemic good that, unlike knowledge, is always intrinsically valuable. Wisdom is similar in this regard and is sometimes considered the highest epistemic good. It encompasses a reflective understanding with practical applications. It helps people grasp and evaluate complex situations and lead a good life. Philosophical skepticism questions the human ability to arrive at knowledge. Some skeptics limit their criticism to certain domains of knowledge. For example, religious skeptics say that it

4216-418: 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

4340-439: Is also responsible for inferential knowledge, in which one or several beliefs are used as premises to support another belief. Memory depends on information provided by other sources, which it retains and recalls, like remembering a phone number perceived earlier. Justification by testimony relies on information one person communicates to another person. This can happen by talking to each other but can also occur in other forms, like

4464-501: Is an encomium to Euagoras who is the father of Nicocles. Isocrates uncritically applauds Euagoras for forcibly taking the throne of Salamis and continuing rule until his assassination in 374 BC. Two years after his completion of the three orations, Isocrates wrote an oration for Archidamus, the prince of Sparta. Isocrates considered the settling of the Thebans colonists in Messene a violation of

4588-458: Is an oversimplification of much more complex psychological processes. Beliefs play a central role in various epistemological debates, which cover their status as a component of propositional knowledge, the question of whether people have control over and are responsible for their beliefs , and the issue of whether there are degrees of beliefs, called credences . As propositional attitudes, beliefs are true or false depending on whether they affirm

4712-424: Is better because it is more stable. Another suggestion focuses on practical reasoning . It proposes that people put more trust in knowledge than in mere true beliefs when drawing conclusions and deciding what to do. A different response says that knowledge has intrinsic value, meaning that it is good in itself independent of its usefulness. Beliefs are mental states about what is the case, like believing that snow

4836-403: Is between analytic and synthetic truths . A sentence is analytically true if its truth depends only on the meaning of the words it uses. For instance, the sentence "all bachelors are unmarried" is analytically true because the word "bachelor" already includes the meaning "unmarried". A sentence is synthetically true if its truth depends on additional facts. For example, the sentence "snow is white"

4960-644: Is called 'East Greek'. Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian Greek had come under 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

5084-448: 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

5208-439: Is correct. Some philosophers, such as Timothy Williamson , reject the basic assumption underlying the analysis of knowledge by arguing that propositional knowledge is a unique state that cannot be dissected into simpler components. The value of knowledge is the worth it holds by expanding understanding and guiding action. Knowledge can have instrumental value by helping a person achieve their goals. For example, knowledge of

5332-416: Is important for explaining the nature of illusions. Constructivism in epistemology is the theory that how people view the world is not a simple reflection of external reality but an invention or a social construction. This view emphasizes the creative role of interpretation while undermining objectivity since social constructions may differ from society to society. According to contrastivism , knowledge

5456-460: Is impossible to have certain knowledge about the existence of deities or other religious doctrines. Similarly, moral skeptics challenge the existence of moral knowledge and metaphysical skeptics say that humans cannot know ultimate reality. Global skepticism is the widest form of skepticism, asserting that there is no knowledge in any domain. In ancient philosophy , this view was accepted by academic skeptics while Pyrrhonian skeptics recommended

5580-443: Is itself a knowledge claim. Another objection says that the abstract reasoning leading to skepticism is not convincing enough to overrule common sense. Fallibilism is another response to skepticism. Fallibilists agree with skeptics that absolute certainty is impossible. Most fallibilists disagree with skeptics about the existence of knowledge, saying that there is knowledge since it does not require absolute certainty. They emphasize

5704-469: Is no universal agreement to what extent they all provide valid justification. Perception relies on sensory organs to gain empirical information. There are various forms of perception corresponding to different physical stimuli, such as visual , auditory , haptic , olfactory , and gustatory perception. Perception is not merely the reception of sense impressions but an active process that selects, organizes, and interprets sensory signals . Introspection

5828-493: Is one of the main branches of philosophy besides fields like ethics , logic , and metaphysics . The term is also used in a slightly different sense to refer not to the branch of philosophy but to a particular position within that branch, as in Plato 's epistemology and Immanuel Kant 's epistemology. As a normative field of inquiry, epistemology explores how people should acquire beliefs. This way, it determines which beliefs fulfill

5952-408: Is relative since it depends on other beliefs. Further theories of truth include pragmatist , semantic , pluralist , and deflationary theories . Truth plays a central role in epistemology as a goal of cognitive processes and a component of propositional knowledge. In epistemology, justification is a property of beliefs that fulfill certain norms about what a person should believe. According to

6076-407: Is relevant to many descriptive and normative disciplines, such as the other branches of philosophy and the sciences, by exploring the principles of how they may arrive at knowledge. The word epistemology comes from the ancient Greek terms ἐπιστήμη (episteme, meaning knowledge or understanding ) and λόγος (logos, meaning study of or reason ), literally, the study of knowledge. The word

6200-412: Is reliable if most of the beliefs it causes are true. A slightly different view focuses on beliefs rather than belief-formation processes, saying that a belief is justified if it is a reliable indicator of the fact it presents. This means that the belief tracks the fact: the person believes it because it is a fact but would not believe it otherwise. Virtue epistemology is another type of externalism and

6324-420: Is sometimes understood as a form of reliabilism. It says that a belief is justified if it manifests intellectual virtues. Intellectual virtues are capacities or traits that perform cognitive functions and help people form true beliefs. Suggested examples include faculties like vision, memory, and introspection. In the epistemology of perception, direct and indirect realists disagree about the connection between

6448-405: Is synthetically true because its truth depends on the color of snow in addition to the meanings of the words snow and white . A priori knowledge is primarily associated with analytic sentences while a posteriori knowledge is primarily associated with synthetic sentences. However, it is controversial whether this is true for all cases. Some philosophers, such as Willard Van Orman Quine , reject

6572-462: Is taken by radical skeptics , who argue that there is no knowledge at all. Epistemologists distinguish between different types of knowledge. Their primary interest is in knowledge of facts, called propositional knowledge . It is a theoretical knowledge that can be expressed in declarative sentences using a that-clause, like "Ravi knows that kangaroos hop". For this reason, it is also called knowledge-that . Epistemologists often understand it as

6696-416: Is the dream argument . It starts from the observation that, while people are dreaming, they are usually unaware of this. This inability to distinguish between dream and regular experience is used to argue that there is no certain knowledge since a person can never be sure that they are not dreaming. Some critics assert that global skepticism is a self-refuting idea because denying the existence of knowledge

6820-414: Is the case if the beliefs are consistent and support each other. According to coherentism, justification is a holistic aspect determined by the whole system of beliefs, which resembles an interconnected web. The view of foundherentism is an intermediary position combining elements of both foundationalism and coherentism. It accepts the distinction between basic and non-basic beliefs while asserting that

6944-405: Is the question of whether knowledge is more valuable than a mere opinion that is true. Knowledge and true opinion often have a similar usefulness since both are accurate representations of reality. For example, if a person wants to go to Larissa , a true opinion about how to get there may help them in the same way as knowledge does. Plato already considered this problem and suggested that knowledge

7068-427: Is wet. According to foundationalism, basic beliefs are the foundation on which all other knowledge is built while non-basic beliefs constitute the superstructure resting on this foundation. Coherentists reject the distinction between basic and non-basic beliefs, saying that the justification of any belief depends on other beliefs. They assert that a belief must be in tune with other beliefs to amount to knowledge. This

7192-407: Is what distinguishes justified beliefs from superstition and lucky guesses. However, justification does not guarantee truth. For example, if a person has strong but misleading evidence, they may form a justified belief that is false. Epistemologists often identify justification as one component of knowledge. Usually, they are not only interested in whether a person has a sufficient reason to hold

7316-601: Is white or that God exists . In epistemology, they are often understood as subjective attitudes that affirm or deny a proposition , which can be expressed in a declarative sentence . For instance, to believe that snow is white is to affirm the proposition "snow is white". According to this view, beliefs are representations of what the world is like. They are kept in memory and can be retrieved when actively thinking about reality or when deciding how to act. A different view understands beliefs as behavioral patterns or dispositions to act rather than as representational items stored in

7440-584: The Eristics , who disputed about theoretical and ethical matters, and the Sophists , who taught political debate techniques. Also, while Isocrates is viewed by many as being a rhetor and practicing rhetoric, he refers to his study as philosophia —which he claims as his own. "Against the Sophists" is Isocrates' first published work where he gives an account of philosophy. His principal method is to contrast his ways of teaching with Sophism. While Isocrates does not go against

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

Late in his life, he married a woman named Plathane (daughter of the sophist Hippias ) and adopted Aphareus (writer) , one of her sons by a previous marriage. There is no evidence for Isocrates' participation in public life during Peloponnesian War (431–404). His professional career is said to have begun with logography : he

It is often roughly divided into the following periods: Mycenaean Greek ( c.  1400–1200 BC ), Dark Ages ( c.  1200–800 BC ), the Archaic or Epic period ( c.  800–500 BC ), and the Classical period ( c.  500–300 BC ). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers . It has contributed many words to English vocabulary and has been

7936-543: The knowledge base of an expert system . Knowledge contrasts with ignorance , which is often simply defined as the absence of knowledge. Knowledge is usually accompanied by ignorance since people rarely have complete knowledge of a field, forcing them to rely on incomplete or uncertain information when making decisions. Even though many forms of ignorance can be mitigated through education and research, there are certain limits to human understanding that are responsible for inevitable ignorance. Some limitations are inherent in

8060-501: The present , future , and imperfect are imperfective in aspect; the aorist , present perfect , pluperfect and future perfect are perfective in aspect. 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)

8184-436: The suspension of belief to achieve a state of tranquility . Overall, not many epistemologists have explicitly defended global skepticism. The influence of this position derives mainly from attempts by other philosophers to show that their theory overcomes the challenge of skepticism. For example, René Descartes used methodological doubt to find facts that cannot be doubted. One consideration in favor of global skepticism

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"):

8556-540: The Aristotelian position on rhetoric as a neutral tool, Isocrates understands rhetoric as an identity-shaping performance that activates and sustains civic identity. The Isocratean position on rhetoric can be thought of as ancient antecedent to the twentieth century theorist Kenneth Burke 's conception that rhetoric is rooted in identification. Isocrates' work has also been described as proto- Pragmatist , owing to his assertion that rhetoric makes use of probable knowledge with

Empiricists hold that all knowledge comes from sense experience, whereas rationalists believe that some knowledge does not depend on it. Coherentists argue that

8804-827: The Greeks, stopping their wars with each other so that they could end the insolence of the Persians. At the end of the Social War in 355 BC, 80-year-old Isocrates wrote an oration addressed to the Athenian assembly entitled On the Peace; Aristotle called it On the Confederacy . Isocrates wrote this speech for the reading public, asking that both sides be given an unbiased hearing. Those in favour of peace have never caused misfortune, while those embracing war lurched into many disasters. Isocrates criticized

8928-512: The Peace of Antalcidas. He was bothered most by the fact that this ordeal would not restore the true Messenians but rather the Helots, in turn making these slaves masters. Isocrates believed justice was most important, which secured the Spartan laws but he did not seem to recognize the rights of the Helots. Ten years later Isocrates wrote a letter to Archidamus, now the king of Sparta, urging him to reconcile

9052-605: The Sophist method of teaching as a whole, he emphasizes his disagreement with bad Sophistic practices. Isocrates' program of rhetorical education stressed the ability to use language to address practical problems, and he referred to his teachings as more of a philosophy than a school of rhetoric. He emphasized that students needed three things to learn: a natural aptitude which was inborn, knowledge training granted by teachers and textbooks, and applied practices designed by educators. He also stressed civic education, training students to serve

9176-439: The aim resolving real problems in the world. Isocrates' innovations in the art of rhetoric paid closer attention to expression and rhythm than any other Greek writer, though because his sentences were so complex and artistic, he often sacrificed clarity. Ancient Greek language Ancient Greek ( Ἑλληνῐκή , Hellēnikḗ ; [hellɛːnikɛ́ː] ) includes the forms of the Greek language used in ancient Greece and

9300-550: 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

He promoted the Greek ideals of freedom, self-control, and virtue; in this, he influenced several Roman rhetoricians, such as Cicero and Quintilian , and influenced the core concepts of liberal arts education . Although Isocrates has been largely marginalized in the history of philosophy, his contributions to the study and practice of rhetoric have received more attention. Thomas M. Conley argues that through Isocrates' influence on Cicero, whose writings on rhetoric were

9548-419: 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

9672-419: The belief following it and is supported by the belief preceding it. The disagreement between internalism and externalism is about the sources of justification. Internalists say that justification depends only on factors within the individual. Examples of such factors include perceptual experience, memories, and the possession of other beliefs. This view emphasizes the importance of the cognitive perspective of

9796-430: The belief in the right way. Another theory states that the belief is the product of a reliable belief formation process. Further approaches require that the person would not have the belief if it was false, that the belief is not inferred from a falsehood, that the justification cannot be undermined , or that the belief is infallible. There is no consensus on which of the proposed modifications and reconceptualizations

9920-438: 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 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

10044-522: The circumstances under which they observed the cup. Evidentialism is an influential internalist view. It says that justification depends on the possession of evidence . In this context, evidence for a belief is any information in the individual's mind that supports the belief. For example, the perceptual experience of rain is evidence for the belief that it is raining. Evidentialists have suggested various other forms of evidence, including memories, intuitions, and other beliefs. According to evidentialism,

10168-609: The city (Athens) to learn through imitation. His students aimed to learn how to serve the city. "At the core of his teaching was an aristocratic notion of arete ("virtue, excellence"), which could be attained by pursuing philosophia – not so much the dialectical study of abstract subjects like epistemology and metaphysics that Plato marked as "philosophy" as the study and practical application of ethics, politics and public speaking ". The philosopher Plato (a rival of Isocrates) founded his own academy in response to Isocrates' foundation. Isocrates accepted no more than nine pupils at

10292-525: The communal aspect of knowledge and historical epistemology examines its historical conditions. Epistemology is closely related to psychology , which describes the beliefs people hold, while epistemology studies the norms governing the evaluation of beliefs. It also intersects with fields such as decision theory , education , and anthropology . Early reflections on the nature, sources, and scope of knowledge are found in ancient Greek , Indian , and Chinese philosophy . The relation between reason and faith

10416-467: The core of liberal arts education as we know it today, including oratory, composition, history, citizenship, culture, and morality. Of the 60 orations in his name available in Roman times, 21 remained in transmission by the end of the medieval period. The earliest manuscripts dated from the ninth or tenth century, until fourth century copies of Isocrates' first three orations were found in a single codex during

10540-402: The death of Pericles , a time in which "wealth – both public and private – was dissipated", and "political decision were ill-conceived and violent" according to the 2020 Encyclopedia Britannica. Isocrates would have been 14 years old when the democracy voted to kill all the male citizens of the small Thracian city of Scione . There are accounts, including that of Isocrates himself, stating that

10664-611: 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

10788-405: The distinction, saying that there are no analytic truths. The analysis of knowledge is the attempt to identify the essential components or conditions of all and only propositional knowledge states. According to the so-called traditional analysis , knowledge has three components: it is a belief that is justified and true. In the second half of the 20th century, this view was put into doubt by

10912-430: The domain of the sophists – came to be viewed as unethical and deceitful. Yet many of Plato's criticisms are hard to substantiate in the actual work of Isocrates; at the end of Phaedrus , Plato even shows Socrates praising Isocrates (though some scholars have taken this to be sarcasm). Isocrates saw the ideal orator as someone who must possess not only rhetorical gifts, but also a wide knowledge of philosophy, science, and

11036-617: The flatterers who had brought ruin to their public affairs. In Panathenaicus, Isocrates argues with a student about the literacy of the Spartans . In section 250, the student claims that the most intelligent of the Spartans admired and owned copies of some of Isocrates' speeches. The implication is that some Spartans had books, were able to read them, and were eager to do so. The Spartans, however, needed an interpreter to clear up any misunderstandings of double meanings which might lie concealed beneath

11160-411: The form of knowledge-how and knowledge by acquaintance . Knowledge-how is a practical ability or skill, like knowing how to read or how to prepare lasagna . It is usually tied to a specific goal and not mastered in the abstract without concrete practice. To know something by acquaintance means to be familiar with it as a result of experiental contact. Examples are knowing the city of Perth , knowing

11284-556: 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 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

11408-472: 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 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

11532-427: The human cognitive faculties themselves, such as the inability to know facts too complex for the human mind to conceive. Others depend on external circumstances when no access to the relevant information exists. Epistemologists disagree on how much people know, for example, whether fallible beliefs about everyday affairs can amount to knowledge or whether absolute certainty is required. The most stringent position

11656-417: The individual in the form of their mental states. It is commonly associated with the idea that the relevant factors are accessible, meaning that the individual can become aware of their reasons for holding a justified belief through introspection and reflection. Externalism rejects this view, saying that at least some relevant factors are external to the individual. This means that the cognitive perspective of

11780-405: The individual is less central while other factors, specifically the relation to truth, become more important. For instance, when considering the belief that a cup of coffee stands on the table, externalists are not only interested in the perceptual experience that led to this belief but also consider the quality of the person's eyesight, their ability to differentiate coffee from other beverages, and

11904-404: The instruction of Isocrates for three to four years. Timotheus had such a great appreciation for Isocrates that he erected a statue at Eleusis and dedicated it to him. According to George Norlin, Isocrates defined rhetoric as outward feeling and inward thought of not merely expression, but reason, feeling, and imagination. Like most who studied rhetoric before and after him, Isocrates believed it

12028-405: The justification of non-basic beliefs depends on coherence with other beliefs. Infinitism presents another approach to the structure of knowledge. It agrees with coherentism that there are no basic beliefs while rejecting the view that beliefs can support each other in a circular manner . Instead, it argues that beliefs form infinite justification chains, in which each link of the chain supports

12152-440: The main topic in epistemology, some theorists focus on understanding rather than knowledge. Understanding is a more holistic notion that involves a wider grasp of a subject. To understand something, a person requires awareness of how different things are connected and why they are the way they are. For example, knowledge of isolated facts memorized from a textbook does not amount to understanding. According to one view, understanding

12276-457: The mind possesses inborn ideas which it can access without the help of the senses. Others hold that there is an additional cognitive faculty, sometimes called rational intuition , through which people acquire nonempirical knowledge. Some rationalists limit their discussion to the origin of concepts, saying that the mind relies on inborn categories to understand the world and organize experience. Foundationalists and coherentists disagree about

12400-409: The mind. This view says that to believe that there is mineral water in the fridge is nothing more than a group of dispositions related to mineral water and the fridge. Examples are the dispositions to answer questions about the presence of mineral water affirmatively and to go to the fridge when thirsty. Some theorists deny the existence of beliefs, saying that this concept borrowed from folk psychology

12524-461: The most widely and continuously studied until the modern era, "it might be said that Isocrates, of all the Greeks, was the greatest." With the neo-Aristotelian turn in rhetoric, Isocrates' work sometimes gets cast as a mere precursor to Aristotle's systematic account in On Rhetoric . However, Ekaterina Haskins reads Isocrates as an enduring and worthwhile counter to Aristotelian rhetoric. Rather than

12648-417: The need to keep an open and inquisitive mind since doubt can never be fully excluded, even for well-established knowledge claims like thoroughly tested scientific theories. Epistemic relativism is a related view. It does not question the existence of knowledge in general but rejects the idea that there are universal epistemic standards or absolute principles that apply equally to everyone. This means that what

12772-499: 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

12896-453: The perceiver and the perceived object. Direct realists say that this connection is direct, meaning that there is no difference between the object present in perceptual experience and the physical object causing this experience. According to indirect realism, the connection is indirect since there are mental entities, like ideas or sense data, that mediate between the perceiver and the external world. The contrast between direct and indirect realism

13020-487: 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

13144-435: The rulers of Salamis on Cyprus. In To Nicocles , Isocrates suggests first how the new king might rule best. For the extent of the rest of the oration, Isocrates advises Nicocles of ways to improve his nature, such as the use of education and studying the best poets and sages. Isocrates concludes with the notion that, in finding the happy mean, it is better to fall short than to go to excess. His second oration concerning Nicocles

13268-644: The sense data it receives from the sensory organs. According to them, the mind can arrive at various additional insights by comparing impressions, combining them, generalizing to arrive at more abstract ideas, and deducing new conclusions from them. Empiricists say that all these mental operations depend on material from the senses and do not function on their own. Even though rationalists usually accept sense experience as one source of knowledge, they also say that important forms of knowledge come directly from reason without sense experience, like knowledge of mathematical and logical truths. According to some rationalists,

13392-411: The standards or epistemic goals of knowledge and which ones fail, thereby providing an evaluation of beliefs. Descriptive fields of inquiry, like psychology and cognitive sociology , are also interested in beliefs and related cognitive processes. Unlike epistemology, they study the beliefs people have and how people acquire them instead of examining the evaluative norms of these processes. Epistemology

13516-430: The state. Students would practice composing and delivering speeches on various subjects. He considered natural ability and practice to be more important than rules or principles of rhetoric. Rather than delineating static rules, Isocrates stressed "fitness for the occasion," or kairos (the rhetor's ability to adapt to changing circumstances and situations). His school lasted for over fifty years, in many ways establishing

13640-407: The structure of knowledge. Foundationalism distinguishes between basic and non-basic beliefs. A belief is basic if it is justified directly, meaning that its validity does not depend on the support of other beliefs. A belief is non-basic if it is justified by another belief. For example, the belief that it rained last night is a non-basic belief if it is inferred from the observation that the street

13764-476: The surface of complicated words. This text indicates that some Spartans were not illiterate. This text is important to scholars' understanding of literacy in Sparta because it indicates that Spartans were able to read and that they often put written documents to use in their public affairs. Because of Plato 's attacks on the sophists, Isocrates' school – having its roots, if not the entirety of its mission, in rhetoric,

13888-517: 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

14012-421: The taste of tsampa , and knowing Marta Vieira da Silva personally. Another influential distinction is between a posteriori and a priori knowledge. A posteriori knowledge is knowledge of empirical facts based on sensory experience, like seeing that the sun is shining and smelling that a piece of meat has gone bad. Knowledge belonging to the empirical science and knowledge of everyday affairs belongs to

14136-409: The truth. More specifically, this and similar counterexamples involve some form of epistemic luck, that is, a cognitive success that results from fortuitous circumstances rather than competence. Following these thought experiments , philosophers proposed various alternative definitions of knowledge by modifying or expanding the traditional analysis. According to one view, the known fact has to cause

14260-400: The validity or truth of a proposition. Certainty, by contrast, is a strong affirmative conviction, meaning that the person is free of doubt that the proposition is true. In epistemology, doubt and certainty play central roles in attempts to find a secure foundation of all knowledge and in skeptical projects aiming to establish that no belief is immune to doubt. While propositional knowledge is

14384-405: The world. While this core sense is of particular interest to epistemologists, the term also has other meanings. Understood on a social level, knowledge is a characteristic of a group of people that share ideas, understanding, or culture in general. The term can also refer to information stored in documents, such as "knowledge housed in the library" or knowledge stored in computers in the form of

14508-475: 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 ,

14632-434: Was a central topic in the medieval period . The modern era was characterized by the contrasting perspectives of empiricism and rationalism. Epistemologists in the 20th century examined the components, structure, and value of knowledge while integrating insights from the natural sciences and linguistics . Epistemology is the philosophical study of knowledge . Also called theory of knowledge , it examines what knowledge

14756-459: Was a hired courtroom speechwriter . Athenian citizens did not hire lawyers; legal procedure required self-representation. Instead, they would hire people like Isocrates to write speeches for them. Isocrates had a great talent for this and he amassed a considerable fortune. According to Pliny the Elder ( NH VII.30) he could sell a single oration for twenty talents . However, his weak voice meant that he

14880-489: Was born into a prosperous family in Athens at the height of Athens' power shortly before the outbreak of the Peloponnesian War (431–404 BC). Suda writes that Isocrates was the son of Theodorus who owned a workshop that manufactured aulos . His mother's name was Heduto. He had a sister and three brothers; two of the brothers were Tisippos ( Ancient Greek : Τίσιππος) and Theomnestos (Ancient Greek: Θεόμνηστος). Isocrates received

15004-661: Was not himself a good public speaker. He played no direct part in state affairs, but he published many pamphlets which influenced the public and provide significant insight into major political issues of the day. Around 392 BC Isocrates set up his own school of rhetoric at the Lyceum . Prior to Isocrates, teaching consisted of first-generation Sophists, such as Gorgias and Protagoras , walking from town to town as itinerants, who taught any individuals interested in political occupations how to be effective in public speaking. Isocrates encouraged his students to wander and observe public behavior in

15128-454: Was only coined in the 19th century to label this field and conceive it as a distinct branch of philosophy. Knowledge is an awareness, familiarity, understanding, or skill. Its various forms all involve a cognitive success through which a person establishes epistemic contact with reality. Knowledge is typically understood as an aspect of individuals, generally as a cognitive mental state that helps them understand, interpret, and interact with

15252-442: Was related to the rulers of Salamis on Cyprus; this was written for the king and his subjects. Isocrates again stresses that the surest sign of good understanding is education and the ability to speak well. The king uses this speech to communicate to the people what exactly he expects of them. Isocrates makes a point in stating that courage and cleverness are not always good, but moderation and justice are. The third oration about Cyprus

15376-510: Was used to persuade ourselves and others, but also used in directing public affairs. Isocrates described rhetoric as "that endowment of our human nature which raises us above mere animality and enables us to live the civilized life." Isocrates unambiguously defined his approach in the speech " Against the Sophists ". This polemic was written to explain and advertise the reasoning and educational principles behind his new school. He promoted broad-based education by speaking against two types of teachers:
