A distinction must here be made between the general theory of life laid down by Aristippus--and the particular application which he made of that theory to his own course of proceeding. What we may observe is, that the Platonic Sokrates (in the Protagoras) agrees in the first, or general theory: whether he would have agreed in the second (or application to the particular case) we are not informed, but we may probably assume the negative. And we find Sokrates (in the Xenophontic dialogue) taking the same negative ground against Aristippus--upon the second point, not upon the first. He seeks to prove that the course of conduct adopted by Aristippus, instead of carrying with it a preponderance of pleasure, will entail a preponderance of pain. He does not dispute the general theory. [Side-note: Kyrenaic theorists after Aristippus.] Though Aristippus and the Kyrenaic sect are recognised as the first persons who laid down this general theory, yet various others apart from them adopted it likewise. We may see this not merely from the Protagoras of Plato, but also from the fact that Aristotle, when commenting upon the theory in his Ethics,[218] cites Eudoxus (eminent both as mathematician and astronomer, besides being among the hearers of Plato) as its principal champion. Still the school of Kyrênê are recorded as a continuous body, partly defending, partly modifying the theory of Aristippus.[219] Hegesias, Annikeris, and Theodôrus are the principal Kyrenaics named: the last of them contemporary with Ptolemy Soter, Lysimachus, Epikurus, Theophrastus, and Stilpon. [Footnote 218: Aristot. Ethic. Nikom. x. 2.] [Footnote 219: Sydenham, in his notes on Philêbus (note 39, p. 76), accuses Aristippus and the Kyrenaics of prevarication and sophistry in the statement of their doctrine respecting Pleasure. He says that they called it indiscriminately [Greek: a)gatho\n] and [Greek: ta)gatho/n]--(a good--The Good)--"they used the fallacy of changing a particular term for a term which is universal, or vice versâ, by the sly omission or insertion of the definite article _The_ before the word Good" (p. 78). He contrasts with this prevarication the ingenuousness of Eudoxus, as the advocate of Pleasure (Aristot. Eth. N. x. 2). I know no evidence for either of these allegations: either for the prevarication of Aristippus or the ingenuousness of Eudoxus.] [Side-note: Theodôrus--Annikeris--Hegesias.]
