Zoilus appears to have been at one time a follower of Isocrates, but subsequently a pupil of Polycrates, whom he heard at Athens, where he was a teacher of rhetoric.

Zoilus also wrote against Isocrates and Plato, who had attacked the style of Lysias of which he approved.
Throughout this mystic religious world it was above all the influence of the late Greek religion, derived from Plato, that also continued to operate; it is filled with the echo of the song, the first note of which was sounded by the Platonists, about the heavenly home of the soul and the homeward journey of the wise to the higher world of light.
An entirely different class of ideas, also termed animistic, is the belief in the world soul, held by Plato, Schelling and others.
He studied with earnest zeal the Greek philosophers; Plato in particular, and the writings of the Stoics, he had fully at command, and his treatise De Anima shows that he himself was able to investigate and discuss philosophical problems.

In the archonship of Polyzelus (367-366), after the death of his father, in his eighteenth year, he came to Athens, and having joined Plato spent twenty years with him.
On the death of Plato (May 347) in the archonship of Theophilus (348-347) he departed to Hermias, tyrant of Atarneus, and, after three years' stay, during the archonship of Eubulus (345-344) he moved to Mitylene, whence he went to Philip of Macedon in the archonship of Pythodotus (343-342), and spent eight years with him as tutor of Alexander.
He also attacked Isocrates, according to Cicero, and perhaps even set up a rival school of rhetoric. At any rate he had pupils of his own, such as Eudemus of Cyprus, Theodectes and Hermias, books of his own, especially dialogues, and even to some extent his own philosophy, while he was still a pupil of Plato.
Well grounded in his boyhood, and thoroughly educated in his manhood, Aristotle, after Plato's death, had the further advantage of travel in his third period, when he was in his prime.
The appointment of Plato's nephew, Speusippus, to succeed his uncle in the Academy induced Aristotle and Xenocrates to leave Athens together and repair to the court of Hermias.
The master and his scholars were called Peripatetics (ol Ert Tov 7reptlredrov), certainly from meeting, like other philosophical schools, in a walk (7repL7raros), and perhaps also, on the authority of Hermippus of Smyrna, from walking and talking there, like Protagora s s and his followers as described in Plato's Protagoras (314 E, 315 e).
Indeed, according to Ammonius, Plato too had talked as he walked in the Academy; and all his followers were called Peripatetics, until, while the pupils of Xenocrates took the name " Academics," those of Aristotle retained the general name.
So diametrical a difference could not have arisen at once_ For, though Aristotle was different from Plato, and brought with.
When Aristotle at the age of eighteen came to Athens, Plato, at the age of sixty-two, had probably written all his dialogues except the Laws; and in the course of the remaining twenty years of his life and teaching, he expounded " the socalled unwritten dogmas " in his lectures on the Good.
The creator, or the divine intellect, with a view to the form of the good, and taking all forms as models, creates in a receptacle (vir080x i, Plato, Timaeus, 49 A) individual impressions which are called things but really change and become without attaining the permanence of being.
Such in brief is the Platonism of the written dialogues; where the main doctrine of forms is confessedly advanced never as a dogma but always as a hypothesis, in which there are difficulties, but without which Plato can explain neither being, nor truth nor goodness, because throughout he denies the being of individual things.
Aristotle knew Plato, was present at his lectures on the Good, wrote a report of them (7rEpi Ta yaBoii), and described this latter philosophy of Plato in his Metaphysics.
Modern critics, who were not present and knew neither, often accuse Aristotle of misrepresenting Plato.
What is more, both Speusippus and Xenocrates founded their own philosophies on this very Pythagoreanism of Plato.
Aristotle had no sympathy with the unwritten dogmas of Plato.
But with the written dialogues of Plato he always continued to agree almost as much as he disagreed.
Like Plato, he believed in real Universals, real essences, real causes; he believed in the unity of the universal, and in the immateriality of essences; he believed in the good, and that there is a good of the universe; he believed that God is a living being, eternal and best, who is a supernatural cause of the motions and changes of the natural world, and that essences and matter are also necessary causes; he believed in the divine intelligence and in the immortality of our intelligent souls; he believed in knowledge going from sense to reason, that science requires ascent to principles and is descent from principles, and that dialectic is useful to science; he believed in happiness involving virtue, and in moral virtue being a control of passions by reason, while the highest happiness is speculative wisdom.
But what he refused to believe with Plato was that reality is not here, but only above; and what he maintained against Plato was that it is both, and that universals and forms, one and many, the good, are real but not separate realities.
A special interest attaches to the dialogues written after the manner of Plato but with Aristotle as principal interlocutor; and some of these, e.g.
Among the didactic writings, the 7rEpi TayaOoii would probably belong to the same time, because it was Aristotle's report of Plato's lectures.
On the whole, then, it seems as if Aristotle began with dialogues during his second period under Plato, but gradually came to prefer writing didactic works, especially in the third period after Plato's death, and in connexion with Alexander.
These early writings show clearly how Aristotle came to depart from Plato.
The philosophy of Plato is dialogue trying to become science; that of Aristotle science retaining traces of dialectic. Secondly as regards subjectmatter, even in his early writings Aristotle tends to widen the scope of philosophic inquiry, so as not only to embrace metaphysics and politics, but also to encourage rhetoric and poetics, which Plato tended to discourage or limit.
The Eudemus and Protrepticus are with Plato; the dialogues on Philosophy and the treatise on Forms are against Plato.
Plato's theory of the soul and its immortality was not the ordinary Greek view derived from Homer, who regarded the body as the self, the soul as a shade having a future state but an obscure existence, and stamped that view on the hearts of his countrymen, and affected Aristotle himself.
This strange, exotic, ascetic view was adopted by some philosophers, and especially by the Pythagoreans, and so transmitted to Plato.
Here we can read the young Aristotle, writing in the form of the dialogue like Plato, avoiding hiatus like Isocrates, and justifying the praises accorded to his style by Cicero, Quintilian and Dionysius.
Nothing could be more like Plato's Phaedo, or more unlike Aristotle's later work on the Soul, which entirely rejects transmigration and allows the next life to sink into the background.
Finally, in the spirit of Plato's Phaedo and the dialogue Eudemus, the Protrepticus holds that the soul is bound to the sentient members of the body as prisoners in Etruria are bound face to face with corpses; whereas the later view of the De Anima is that the soul is the vital principle of the body and the body the necessary organ of the soul.
Accordingly in this dialogue he attacked Plato's fundamental position, both in its written and in its unwritten presentment, as a.
Thus early did Aristotle begin, even in Plato's lifetime, to oppose.
Plato's hypothesis of supernatural forms, and advance his own.
Aristoxenus, at the beginning of the second book of the Harmonics,, gives a graphic account of the astonishment caused by these lectures, of Plato, and of their effect on the lectures of Aristotle.
From this rare personal reminiscence we see at a glance that the mind of Plato and the mind of Aristotle were son, different, that their philosophies must diverge'; the one towards the supernatural, the abstract, the discursive, and the other towards thenatural, the substantial, the scientific.
Aristotle then even in the second period of his life, while Plato, was still alive, began to differ from him in metaphysics.
After Plato's death, coming to his third period he made a further departure from Platonism in his didactic works on politics and rhetoric, written in connexion with Alexander and Theodectes.
Still more marked was his departure from Plato as regards rhetoric. Plato in the Gorgias, (501 A) had contended that rhetoric is not an art but an empirical practice (rpt/37) KaL Epirecpia); Aristotle in the Gryllus (Fragm.
On the whole then, in his early dialectical and didactic writings, of which mere fragments remain, Aristotle had already diverged from Plato, and first of all in metaphysics.
After his master's death, in the third period of his own life, and during his connexion with Alexander, but before the final construction of his philosophy into a system, he was tending to write more and more in the didactic style; to separate from dialectic, not only metaphysics, but also politics, rhetoric and poetry; to admit by the side of philosophy the arts of persuasive language; to think it part of their legitimate work to rouse the passions; and in all these ways to depart from the ascetic rigidity of the philosophy of Plato, so as to prepare for the tolerant spirit of his own, and especially for his ethical doctrine that virtue consists not in suppressing but in moderating almost all human passions.
He was really, as we have seen, a prolific writer from the time when he was a young man under Plato's guidance at Athens; beginning with dialogues in the manner of his master, but afterwards preferring to write didactic works during the prime of his own life between thirty-eight and fifty (347-335-334), and with the further advantage of leisure at Atarneus and Mitylene, in Macedonia and at home in Stagira.
Finally he died without completing some of his works, such as the Politics, and notably that work of his whole philosophic career and foundation of his whole philosophy - the Metaphysics - which, projected in his early criticism of Plato's philosophy of universal forms, gradually developed into his positive philosophy of individual substances, but remained unfinished after all.
To put one extreme case, about the soul he could think at first in the Eudemus like Plato that it is imprisoned in the body, and long afterwards in the De Anima like himself that it is the immateriate essence of the material bodily organism.
With them came philosophical poems, such as those of Xenophanes and Empedocles; the epical history of Herodotus; the dramatic philosophy of Plato.
As to the fragments, we are safe in saying that the early dialogues in the manner of Plato were written under the influence of Plato, and that the subsequent didactic writings connected with Alexander were written more under the influence of Philip and Alexander.
Turning to the extant writings, we find that some are more under the influence of Plato, while others are more original and Aristotelian.
In brief then the common ground of the Categories and the Metaphysics is the fundamental position that all things are substances having belonging to them universals and attributes, which have no separate being as Plato falsely supposed.
We have seen how anxious Aristotle was to be considered one of the Platonists, how reluctant he was to depart from Plato's hypothesis of forms, and how, in denying the separability, he retained the Platonic belief in the reality and even in the unity of the universal.
The first difference then between the Categories and the Metaphysics is in the nature of an attribute; and the theory of inherence in the Categories is nearer to Plato and more rudimentary than the theory of predication in the Metaphysics.
The second difference is still nearer to Plato and more rudimentary, and is in the nature of substance.
The question then arises, what sort of substance can be predicate; and in the Categories Aristotle gave an answer, which would have been impossible, if he had not, under Plato's influence, accepted both the unity and the substantiality of the universal.
The only logical conclusion is that the Categories, being nearer to Plato on the nature of attributes, and still nearer on the relation of universals to substances, is earlier than the Metaphysics.
But this lapse only shows how powerful a dominion Plato exercised over Aristotle's soul to the last; for it arises out of the pupil still accepting from hiAmaster the unity of the universal though now applying it, not to classes, but to essences.
But in spite of this great logical achievement, he continued throughout the discourse to accept Plato's grammatical analysis of all sentences into noun and verb, which indeed applies to the proposition as a sentence but does not give its particular elements.
It is nearer to Plato's analysis of the sentence, and no logician would have gone back to it, after the Prior Analytics.
At first he adopted the somewhat ascetic views of his master about soul and body, and about goods of body and estate; but before Plato's death he had rejected the hypothesis of forms, formal numbers and the form of the good identified with the one, by which Plato tried to explain moral phenomena; while his studies and teaching on rhetoric and poetry soon began to make him take a more tolerant view than Plato did of men's passions.
Throughout his whole subsequent life, however, he retained the fundamental doctrine, which he had learnt from Plato, and Plato from Socrates, that virtue is essential to happiness.
Moreover, the successors of Plato in the Academy, Speusippus and Xenocrates, showed the same belief in the essentiality of virtue.
It is probable that when, after Plato's death and the accession of Speusippus in 347, Aristotle with Xenocrates left Athens to visit his former pupil Hermias, the three discussed this moderate system of Ethics in which the two philosophers nearly agreed.
The good of Ethics is human good; and human good is happiness, not the universal good or form of the good to which Plato subordinated human happiness.
After this, it can never be said that the earlier books of the Eudemian Ethics are so good a preparation as those of the Nicomachean Ethics for the distinction between prudence (Opov j ats) and wisdom (a001a), which is the main point of the common books, and one of Aristotle's main points against Plato's philosophy.
Meanwhile, however, the truth about the Eudemian Ethics in general is that it was an earlier rudimentary sketch written by Aristotle, when he was still struggling, without quite succeeding, to get over Plato's view that there is one philosophical knowledge of universal good, by which not only the dialectician and mathematician must explain the being and becoming of the world, but also the individual and the statesman guide the life of man.
Secondly, the Eudemian Ethics, while not agreeing with Plato's Republic that the just can be happy by justice alone, does not assign to the external goods of good fortune (Eutu X ia) the prominence accorded to them in the Nicomachean Ethics as the necessary conditions of all virtue, and the instruments of moral virtue.
The opposition of divine good fortune according to impulse to that which is contrary to impulse reminds us of Plato's point in the Phaedrus that there is a divine as well as a diseased madness.
Because, then, it is very like, but more rudimentary and more Platonic, we conclude that the Eudemian is an earlier draft of the Nicomachean Ethics, written by Aristotle when he was still in process of transition from Plato's ethics to his own.
It has another characteristic which points to its being an early work of Aristotle, when he was still under the influence of Plato's style; namely its approximation to dialogue.
No doubt, rational evidences had appeared in books of rhetoric, as we see from Plato's Phaedrus, 266-267,where we find proofs,probabilities, refutation and maxim, but mixed up with other evidences.
The truth is that the Metaphysics both precedes and follows the Physics, because it had been all along occupying Aristotle ever since he began to differ from Plato's metaphysical views and indeed forms a kind of presupposed basis of his whole system.
Plato and Speusippus in the Ethics, Eudoxus and Callippus in the Metaphysics, he was writing these passages after the deaths of these persons; but he might have been also writing the Ethics and the Metaphysics both beforehand and afterwards.
The reason is that Aristotle was primarily a metaphysician half for and half against Plato, occupied himself with metaphysics all his philosophical life, made the science of things the universal basis of all sciences without destroying their independence, and so gradually brought round philosophy from universal forms to individual substances.
Beyond knowledge lies opinion, beyond discovery disputation, beyond philosophy and science dialectic between man and man, which was much practised by the Greeks in the dialogues of Socrates, Plato, the Megarians and Aristotle himself in his early manhood.
With Plato, who thought that the interrogation of man is the best instrument of truth, dialectic was exaggerated into a universal science of everything that is.
Aristotle was the founder of Logic; because, though others, and especially Plato, had made occasional remarks about reason (X yos), Aristotle was the first to conceive it as a definite subject of investigation.
On the whole, the interpretation which best suits all the passages is that extraneous discourses mean any extra-scientific dialectical discussions, oral or written, occurring in dialogues by Plato, or by Aristotle, or by anybody else, or in ordinary conversation, on any subject under the sun.
There are then no separate universal forms, as Plato supposed.
So can we men, not, as Plato thought, by having in our souls universal principles innate but forgotten, but by acquiring universal principles from sense, which is the origin of knowledge, arrive at judgments which are true, and true because they agree with the things which we know by sense, by inference and by science.
Grote indeed intended to write a general account of Aristotle like that of Plato; but his Aristotle went little further than the logical writings.
The Timaeus of Plato in the Latin version of Chalcidius was known to him as to his contemporaries and predecessors, and probably he had access to translations of the Phaedo and Meno.
In More's house you would see that Plato's Academy was revived again, only, whereas in the Academy the discussions turned upon geometry and the power of numbers, the house at Chelsea is a veritable school of Christian religion.
Empedocles, Plato and Aristotle; Telesio, Bruno and Campanella; Leibnitz; the idealists, Schopenhauer and Hartmann, Fechner and Paulsen; and the materialist, Haeckel - all have agreed in according some sort of appetition to Nature.
Of this view the part which was not Aristotle's, the state of " universalia ante rem," was due to the Neoplatonists, who interpreted the " separate forms " of Plato to be ideas in intellect, and handed down their interpretation through St Augustine to the medieval Realists like Aquinas, who thus combined Neoplatonism with Aristotelianism.
That work contains the doctrine common to the Essenes with Plato, and suggestive of Persian Dualism, that God is the author of good only.
His commentaries on Plato and Ptolemy are lost.
It was a centre of Greek civilization, devoted especially to the worship of Artemis, and producing famous teachers, of whom Stephen the Byzantine mentions Ariston, Kerykos and Plato.
Thus the metaphysic of Plato finds reality only in the "Idea," of which all phenomena are merely imperfect copies.
He was the first who published a book on the Pythagorean doctrines, a treatise of which Plato made use in the composition of his Timaeus.
It is probable that Aesop did not commit his fables to writing; Aristophanes (Wasps, 1259) represents Philocleon as having learnt the "absurdities" of Aesop from conversation at banquets, and Socrates whiles away his time in prison by turning some of Aesop's fables "which he knew" into verse (Plato, Phaedo, 61 b).
He withdrew subsequently with a number of fellow disciples to Megara, and it has been conjectured, though there is no direct evidence, that this was the period of Plato's residence in Megara, of which indications appear in the Theaetetus.
The principal are - in Italian, the famous Il Galateo (1558), a treatise of manners, which has been translated into several languages, and in Latin, De officiis, and translations from Thucydides, Plato and Aristotle.
Commentaries on Plato, mentioned by Porphyry in his life of Plotinus, have also been lost.
He became famous as a translator of Homer and Plato.
It is thus a dialogue within a dialogue, after the manner of Plato, but a conversation of sufficient length to occupy several days (though represented as taking place in one) could not be conveyed in a style similar to the short conversations of Socrates.
At GÃ¶ttingen he studied Plato with Heeren, New Testament Greek with Eichhorn and natural science with Blumenbach.
On the other hand, it is argued that the authority of Galen and Cicero (pro Cluentio) place it beyond a doubt that, so far from being allowed to pass with impunity, the offence in question was sometimes punished by death; that the authority of Lysias is of doubtful authenticity; and that the speculative reasonings of Plato and Aristotle, in matters of legislation, ought not to be confounded with the actual state of the laws.
The needless bitterness of his attacks upon Plato (in the Comparatio Aristotelis et Platonis), which drew forth a powerful response from Bessarion (q.v.), and the manifestly hurried and inaccurate character of his translations of Plato, Aristotle and other classical authors, combined to ruin his fame as a scholar, and to endanger his position as a teacher of philosophy.
From a life by Diogenes Laertius, we learn that he studied at Athens under Plato, but, being dismissed, passed over into Egypt, where he remained for sixteen months with the priests of Heliopolis.
In this aversion to a purely or mainly intellectual training may be traced a recoil from the systematic metaphysics of Plato and Aristotle, whose tendency was to subordinate the practical man to the philosopher.
Hence, in the second place, Plato and Aristotle had assumed a perfect state with laws to guide the individual aright.
The founders of the school sought to invest their doctrines with the halo of tradition by ascribing them to Pythagoras and Plato, and there is no reason to accuse them of insincerity.
They went back to the later period of Plato's thought, the period when Plato endeavoured to combine his doctrine of Ideas with the Pythagorean number-theory, and identified the Good with the One, the source of the duality of the Infinite and the Measured (rd .bretpov and 71-pas) with the resultant scale of realities from the One down to the objects of the material world.
In this system we distinguish not only the asceticism of Pythagoras and the later mysticism of Plato, but also the influence of the Orphic mysteries.
The Ideas of Plato are no longer self-subsistent entities; they are the elements which constitute the content of spiritual activity.
It connects the teaching of Plato with the doctrines of Neoplatonism and brings it into line with the later Stoicism and with the ascetic system of the Essenes.
Modern critics would place his birth later, - between 444 and 436 B.C.,- because, in Plato's Republic, of which the scene is laid about 430 B.C., Cephalus, the father of Lysias, is among the dramatis personae, and the emigration of Lysias to Thurii was said to have followed his father's death.
The latter statement, however, rests only on the Plutarchic life; nor can Plato's dialogue be safely urged as a minutely accurate authority.
The opening scene of Plato's Republic is laid at the house of his eldest son, Polemarchus, in Peiraeus.
Litt., gives the date of birth as about 4501 the Sicilian family were well known to Plato, and that their houses must often have been hospitable to such gatherings..
This has generally been regarded as Plato's own work; but the certainty of this conclusion will be doubted by those who observe (I) the elaborate preparations made in the dialogue for a recital of the EpwrcKOS which shall be verbally exact, and (2) the closeness of the criticism made upon it.
It led, through Dion, to the several visits of Plato to Sicily under both the elder and the younger Dionysius.
Some of the ancients connected her with the earth; Plato, followed by the Stoics, derived her name from tip, the air.
He was much influenced by Lucretius and had read Plato.
Various anticipations of pragmatism in the history of philosophy are noted in Schiller's Plato or Protagoras ?
The comic poets satirized them, and Plato and Demosthenes inveighed against them; but they continued to spread, with all their fervid enthusiasm, their superstition and their obscene practices, wide among the people, whose religious cravings were not satisfied with the purely external religions of Hellenism.
Plato mentions that the Phrygian words for "dog," "fire," &c., were the same as the Greek; and to these we may add from inscriptions the words for "mother," "king," &c. A few inscriptions of the ancient period are known, and a larger number of the Roman period have been published in the Oesterreichische Jahreshefte (1905).
The Buddha found it (as Plato also found it) 1 in the influence exercised upon one life by a desire felt in the previous life.
In depth of philosophic insight, in the method of Socratic questioning often adopted, in the earnest and elevated tone of the whole, in the evidence they afford of the most cultured thought of the day, these dialogues constantly remind the reader of the dialogues of Plato.
For while Hegel, depending on a numerical proportion suggested by Plato, hinted in a single sentence that it might be a mistake to look for a planet between Mars and Jupiter, Giuseppe Piazzi (q.v.) had already discovered the first of the asteroids (Ceres) on the ist of January 1801.
Besides philosophical studies, where he now added Aristotle to Plato, he read Homer and the Greek tragedians, made extracts from books, attended lectures on physiology, and dabbled in other sciences.
The Phenomenology stands to the Encyklopadie somewhat as the dialogues of Plato stand to the Aristotelian treatises.
Meyer and others), or accept the tradition that it was founded during the first Messenian War, which necessitated a prolonged absence from Sparta on the part of both kings (Plato, Laws, iii.
Gradually they extended their powers, aided by the jealousy between the royal houses, which made it almost impossible for the two kings to co-operate heartily, and from the 5th to the 3rd century they exercised a growing despotism which Plato justly calls a tyrannis (Laws, 692).
On the History of Animals no commentary at all exists, and Plato's Republic is substituted for the then inaccessible Politics.
He was the author of a commentary on the Republic of Plato, which is lost, but we still possess by him a short but comprehensive work (ITparrlyuais) on the duties of a general.
Finally, the practice of rhetoric and eristic, which presently became prominent in sophistical teaching, had, or at any rate seemed to have, a mischievous effect upon conduct; and the charge of seeking, whether in exposition or in debate, not truth but victory - which charge was impressively urged against the sophists by Plato - grew into an accusation of holding and teaching immoral and unsocial doctrines, and in our own day has been the subject of eager controversy.
It is plain that Prodicus was an affected pedant; yet his simple conventional morality found favour, and Plato (Rep. 600 C) couples him with Protagoras in his testimony to the popularity of the sophists and their teaching.
He had already reached the height of his fame when Plato opened a rival school at the Academy, and pointedly attacked him in the Gorgias, the Plaaedrus and the Republic. Thenceforward, there was a perpetual controversy between the rhetorician and the philosopher, and the struggle of educational systems continued until, in the next generation, the philosophers were left in possession of the field.
Again, as the Socratics - Plato himself, when he established himself at the Academy, being no exception - were, like their master, educators rather than philosophers, and in their teaching laid especial stress upon discussion, they, too, were doubtless regarded as sophists, not by Isocrates only, but by their contemporaries in general; and it may be conjectured that the disputatious tendencies of the Megarian school made it all the more difficult for Plato and others to secure a proper appreciation of the difference between dialectic, or discussion with a view to the discovery of truth, and eristic, or discussion with a view to victory.
That sophistry must be studied in its historical development was clearly seen by Plato, whose dialogue called the Sophist contains a formal review of the changing phases and aspects of sophistical teaching.
Thus the first and second definitions represent the founders of the sophistry of culture, Protagoras and Prodicus, from the respective points of view of the older Athenians, who disliked the new culture, and the younger Athenians, who admired it; the third and fourth definitions represent imitators to whom the note of itinerancy was not applicable; the fifth definition represents the earlier eristics, contemporaries of Socrates, whom it was necessary to distinguish from the teachers of forensic oratory; the sixth is framed to meet the anomalous case of Socrates, in whom many saw the typical sophist, though Plato conceives this view to be unfortunate; and the seventh and final definition, having in view eristical sophistry fully developed, distinguishes it from SfµoXoyuci, i.e.
Now it is easy to see that in this careful statement Plato recognizes three periods.
The fifth and sixth definitions represent the close of the 5th century, when sophistry handled eristically, and perhaps, though Plato demurs to the inclusion, dialectically, questions of justice, injustice and the like, Su
Whereas, when sophistry began, prose composition was hardly practised in central Greece, the sophists were still the leaders in literature and oratory when Plato wrote the Republic, and they had hardly lost their position when Demosthenes delivered the Philippics.
As for the classification of sophistical methods, so for their criticism, the testimony of Plato is all-important.
It may be conjectured that, when he emerged from the purely Socratic phase of his earlier years, Plato gave himself to the study of contemporary methods of education and to the elaboration of an educational system of his own, and that it was in this way that he came to the metaphysical speculations of his maturity.
Plato's criticisms of the sophists are then, in the opinion of the present writer, no mere obiter dicta, introduced for purposes of literary adornment or dramatic effect, but rather the expressions of profound and reasoned conviction, and, as such, entitled at any rate to respect.
For the details of Plato's critique the reader should go not to the summaries of commentators, but to the dialogues themselves.
In this place it is sufficient to say that, while Plato accounts no education satisfactory which has not knowledge for its basis, he emphatically prefers the scepticism of Socrates, which, despairing of knowledge, seeks right opinion, to the scepticism of the sophists, which, despairing of knowledge, abandons the attempt to better existing beliefs.
Nor can we regard " Plato and his followers as the authorized teachers of the Greek nation and the sophists as the dissenters."
On the contrary, the sophists were in quiet possession of the field when Plato, returning to Athens, opened the rival school of the Academy; and, while their teaching in all respects accommodated itself to current opinion, his, in many matters, ran directly counter to it.
Various as were the phases through which sophistry passed between the middle of the 5th century and the middle of the 4th, the sophists - Socrates himself being no exception - had in their declared antagonism to philosophy a common characteristic; and, if in the interval, philosophical speculation being temporarily suspended, scepticism ceased for the time to be peculiar, at the outset, when Protagoras and Gorgias broke with the physicists, and in the sequel, when Plato raised the cry of " back to Parmenides," this common characteristic was distinctive.
And, though the modern critic will not be prepared with Plato to deny the name of education to all teaching which is not based upon an ontology, it may nevertheless be thought that normal sophistry - as opposed to the sophistry of Socrates - was in various degrees unsatisfactory, in so far as it tacitly or confessedly ignored the " material " element of exposition by reasoning.
Excellent as a statement of the aim and method of Isocrates, and tolerable as a statement of those of Gorgias, these phrases are inexact if applied to Protagoras, who, making " civic virtue " his aim, regarded statesmanship and administration as parts of " civic virtue ", and consequently assigned to oratory no more than a subordinate place in his programme, while to the eristics - whose existence is attested not only by Plato, but also by Isocrates and Aristotle - and to Socrates - whom Grote himself accounts a sophist - the description is plainly and palpably inappropriate.
Now this view is inconsistent with the evidence of Plato, who, in the Sophist, in his final and operative definition, gives prominence to the eristical element, and plainly accounts it the main characteristic not indeed of the sophistry of the 5th century, but of the sophistry of the 4th.
In particular he allows that " there was at any rate enough of charlatanism in Protagoras and Hippias to prevent any ardour for their historical reputation," that the sophists generally " had in their lifetime more success than they deserved," that it was " antagonism to their teaching which developed the genius of Socrates," and, above all, that, " in his anxiety to do justice to the Sophist, Grote laid more stress than is at all necessary on the partisanship of Plato."
That Plato was not careful to distinguish the Megarians and the Cynics from the eristical sophists, and that the disputants of the 4th century affected some of the mannerisms of the greatest disputant of the 5th century, he willingly concedes.
Nor is it possible to accept the statements that " the splendid genius, the lasting influence, and the reiterated polemics of Plato have stamped the name sophist upon the men against whom he wrote as if it were their recognized, legitimate and peculiar designation," and that " Plato not only stole the name out of general circulation,.
Nor is Grote altogether just in his account of Plato's attitude towards the several sophists, or altogether judicious in his appreciation of Plato's testimony.
Indeed, the author of this article finds in the writings of Plato a grave and discriminating study of the several forms of sophistry, and no trace whatsoever of that blind hostility which should warrant us in neglecting his clear and precise evidence.
In a word, the present writer agrees with Grote that the sophists were not a sect or school with common doctrine or method; that their theoretical and practical morality was neither above nor below that of their age, being, in fact, determined by it; and that Plato and his followers are not to be regarded as the authorized teachers of the Greek nation, nor the sophists as the dissenters, but vice versa.
The term has been applied in modern usage, due to Plato's Symposium, to a collection of opinions of different writers on a given subject.
He tells us that he drew largely from Plato, Aristotle, Theophrastus and writings of the Peripatetics.
The de Legibus, a sequel to this work in imitation of Plato's Laws, is drawn largely from Chrysippus.
The idea is drawn from Aristo of Chios, and the materials largely derived from Xenophon and Plato.
In 1856 Grote began to prepare his works on Plato and Aristotle.
Plato and the Other Companions of Sokrates (3 vols.) appeared in 1865, but the work on Aristotle he was not destined to complete.
In dealing with Plato he was handicapped by this very common sense, which prevented him from appreciating the theory of ideas in its widest relations.
His Plato is important in that it emphasizes the generally neglected passages of Plato in which he seems to indulge in mere Socratic dialectic rather than to seek knowledge; it is, therefore, to be read as a corrective to the ordinary criticism of Plato.
The Plato was finally edited by Alexander Bain in 4 vols.
In this way the Presocratics and Sophists, and still more Socrates and Plato, threw out hints on sense and reason, on inferential processes and scientific methods which may be called anticipations of logic. But Aristotle was the first to conceive of reasoning itself as a definite subject of a special science, which he called analytics or analytic science, specially designed to analyse syllogism and especially demonstrative syllogism, or science, and to be in fact a science of sciences.
On the other hand, the demonstrations of mathematical sciences of his time, and the logical forms of deduction evinced in Plato's dialogues, provided him with admirable examples of deduction, which is also the inference most capable of analysis.
The sophist Protagoras had distinguished various kinds of sentences, and Plato had divided the sentence into noun and verb, signifying a thing and the action of a thing.
Among the dialecticians, Socrates had used inductive arguments to obtain definitions as data of deductive arguments against his opponents, and Plato had insisted on the processes of ascending to and descending from an unconditional principle by the power of giving and receiving argument.
Logic arose, at least for the Western world, in the golden age of Greek speculation which culminated in Plato and Aristotle.
It is with Aristotle that the bookish tradition begins to dominate the evolution of logic. The technical perfection of the analysis which he offers is, granted the circle of presuppositions within which it works, so decisive, that what precedes, even Plato's logic, is not unnaturally regarded as merely preliminary and subsidiary to it.
It is equally no accident that the name of Protagoras is to be connected, in Plato's view at least, with the rival school of Heracliteans.
The Theaetetus indeed, in which Plato essays to deal with them, is in the broad sense of the word logical, the first distinctively logical treatise that has come down to us.
As presented to us, for example, in Plato's surely not altogether hostile caricature in the Euthydemus, they mark the intellectual preparation for, and the moral need for, the advance of the next generation.
Plato's problem was to find a way of ' Nothing is.
Between Euclides and Antisthenes the Socratic induction and universal definition were alike discredited from the point of view of the Eleatic logic. It is with the other point of doctrine that Plato comes to grips, that which allows of a certainty or knowledge consisting in an analysis of a compound into simple elements themselves not known.
It is the wealth of illustration with which Plato expresses his meaning, and the range of application which he gives the idea - to the class 4 For whom see Diimmler, Antisthenica (1882, reprinted in his Kleine Schriften, 1901).
Plato replies with the doctrine of the interpenetration of ideas, obviously not of all with all, but of some with some, the formula of identity in difference within thought itself.
Plato proceeds to explain by his principle of difference both privative and negative predicates, and also the possibility of false predication.
Even Plato, however, perhaps scarcely shows that with it, and nothing else but it, error is explained.
Plato's division is nevertheless neither syllogism nor exclusiva.
Plato's successors in the Academy must have developed a system of grammaticological categories which Aristotle could make his own.
The first may have linked on to the series of Plato's dialogues of search, and to put the Parmenides before it is impossible.
For Plato's logic this question only has interest on account of the introduction of an 'AptoToTO?
The doctrine of latency is mystical and savours of Plato's reminiscence (anamnesis).
Plato is full of the faith of mathematical physics.
For those of the school of Plato whc refused the apostasy of the new academy, there was hope either in the mathematical side of the Pythagoreo.
Neoplatonism had accepted the Aristotelian logic with its sharper definition than anything handed down from Plato, and, except the logic of the Sceptics, there was no longer any rival discipline of the like prestige.
He has read Plato's Theaetetus in the light of Baconian and individualist preconceptions.
Plato had made God accessible to the highest knowledge as the transcendent idea, remote from the world.
For his zeal he was confined for five years in the fortress of Kolberg, where he studied Plato and the Greek poets.
On the contrary, Plato and other Attic writers use the word to include interpreters and admirers - in short, the whole " spiritual kindred " - of Homer.
Other names of the pre-Socratic and Socratic times are mentioned by Xenophon, Plato and Aristotle.
The author of the Hipparchus is evidently influenced by the anti-democratical tendencies in which he only followed Plato.
While, on one hand, he combines much that had been suggested by Parmenides, Pythagoras and the Ionic schools, he has germs of truth that Plato and Aristotle afterwards developed; he is at once a firm believer in Orphic mysteries, and a scientific thinker, precursor of the physical scientists.
In Plato for the first time we find a truly dualistic conception of the universe.
Both groups had their scientific theologians who sought to vindicate their characteristic doctrines, the Adoptianist divines holding by the Aristotelian philosophy, and the Modalists by that of the Stoics; while the Trinitarians (Tertullian, Hippolytus, Origen, Novatian), on the other hand, appealed to Plato.
For older thinkers like Plato and Aristotle the perfect life was that of the citizen and householder; but the Cynics were individualists, citizens of the world without loyalty or respect for the ancient city state, the decay of which was coincident with their rise.
A subordinate matter in the book that attracted much attention at the time is the conception of the "Plastic Medium," which is a mere revival of Plato's "World-Soul," and is meant to explain the existence and laws of nature without referring all to the direct operation of God.
Cudworth's ideas, like Plato's, have "a constant and never-failing entity of their own," such as we see in geometrical figures; but, unlike Plato's, they exist in the mind of God, whence they are communicated to finite understandings.
This, according to 1 The word Idola is manifestly borrowed from Plato.
