The statement made by Plato in the Phædon — That Aristippus and Kleombrotus were not present at the death of Sokrates, but were said to be in Ægina — is cited as an example of Plato’s ill-will and censorious temper (Demetr. Phaler. s. 306). But this is unfair. The statement ought not to be so considered, if it were true: and if not true, it deserves a more severe epithet. We read in Athenæus various other criticisms, citing or alluding to passages of Plato, which are alleged to indicate ill-nature; but many of the passages cited do not deserve the remark.
No Sokratic school — each of the companions took a line of his own.
It is common for historians of philosophy to speak of a Sokratic school: but this phrase, if admissible at all, is only admissible in the largest and vaguest sense. The effect produced by Sokrates upon his companions was, not to teach doctrine, but to stimulate self-working enquiry, upon ethical and social subjects. Eukleides, Antisthenes, Aristippus, each took a line of his own, not less decidedly than Plato. But unfortunately we have no compositions remaining from either of the three. We possess only brief reports respecting some leading points of their doctrine, emanating altogether from those who disagreed with it: we have besides aphorisms, dicta, repartees, bons-mots, &c., which they are said to have uttered. Of these many are evident inventions; some proceeding from opponents and probably coloured or exaggerated, others hardly authenticated at all. But if they were ever so well authenticated, they would form very insufficient evidence on which to judge a philosopher — much less to condemn him with asperity.[18] Philosophy (as I have already observed) aspires to deliver not merely truth, but reasoned truth. We ought to know not only what doctrines a philosopher maintained, but how he maintained them:—what objections others made against him, and how he replied:—what objections he made against dissentient doctrines, and what replies were made to him. Respecting Plato and Aristotle, we possess such information to a considerable extent:—respecting Eukleides, Antisthenes, and Aristippus, we are without it. All their compositions (very numerous, in the case of Antisthenes) have perished.
[18] Respecting these ancient philosophers, whose works are lost, I transcribe a striking passage from Descartes, who complains, in his own case, of the injustice of being judged from the statements of others, and not from his own writings:—“Quod adeo in hâc materiâ verum est, ut quamvis sæpe aliquas ex meis opinionibus explicaverim viris acutissimis, et qui me loquente videbantur eas valdé distincté intelligere: attamen cum eas retulerunt, observavi ipsos fere semper illas ita mutavisse, ut pro meis agnoscere amplius non possem. Quâ occasione posteros hic oratos volo, ut nunquam credant, quidquam à me esse profectum, quod ipse in lucem non edidero. Et nullo modo miror absurda illa dogmata, quæ veteribus illis philosophis tribuuntur, quorum scripta non habemus: nec propterea judico ipsorum cogitationes valdé à ratione fuisse alienas, cum habuerint præstantissima suorum sæculorum ingenia; sed tantum nobis perperam esse relatas.” (Descartes, Diss. De Methodo, p. 43.)
EUKLEIDES.
Eukleides of Megara — he blended Parmenides with Sokrates.
Eukleides was a Parmenidean, who blended the ethical point of view of Sokrates with the ontology of Parmenides, and followed out that negative Dialectic which was common to Sokrates with Zeno. Parmenides (I have with already said)[19] and Zeno after him, recognised no absolute reality except Ens Unum, continuous, indivisible: they denied all real plurality: they said that the plural was Non-Ens or Nothing, i.e. nothing real or absolute, but only apparent, perpetually transient and changing, relative, different as appreciated by one man and by another. Now Sokrates laid it down that wisdom or knowledge of Good, was the sum total of ethical perfection, including within it all the different virtues: he spoke also about the divine wisdom inherent in, or pervading the entire Kosmos or universe.[20] Eukleides blended together the Ens of Parmenides with the Good of Sokrates, saying that the two names designated one and the same thing: sometimes called Good, Wisdom, Intelligence, God, &c., and by other names also, but always one and the same object named and meant. He farther maintained that the opposite of Ens, and the opposite of Bonum (Non-Ens, Non-Bonum, or Malum) were things non-existent, unmeaning names, Nothing,[21] &c.: i.e. that they were nothing really, absolutely, permanently, but ever varying and dependent upon our ever varying conceptions. The One — the All — the Good — was absolute, immoveable, invariable, indivisible. But the opposite thereof was a non-entity or nothing: there was no one constant meaning corresponding to Non-Ens — but a variable meaning, different with every man who used it.
