Menedêmus the Eretrian, one among the hearers and admirers of Stilpon, combined even more than Stilpon the attributes of the Cynic with those of the Megaric. He was fearless in character, and uncontrouled in speech, delivering harsh criticisms without regard to offence given: he was also a great master of ingenious dialectic and puzzling controversy.[135] His robust frame, grave deportment, and simplicity of life, inspired great respect; especially as he occupied a conspicuous position, and enjoyed political influence at Eretria. He is said to have thought meanly both of Plato and Xenokrates. We are told that Menedêmus, like Antisthenes and Stilpon, had doctrines of his own on the subject of predication. He disallowed all negative propositions, admitting none but affirmative: moreover even of the affirmative propositions, he disallowed all the hypothetical, approving only the simple and categorical.[136] [Footnote 135: Diog. L. ii. 127-134. [Greek: ê)=n ga\r kai\ e)piko/ptês kai\ par)r(êsiastê/s.]] [Footnote 136: Diog. L. ii. 134.] It is impossible to pronounce confidently respecting these doctrines, without knowing the reasons upon which they were grounded. Unfortunately these last have not been transmitted to us. But we may be very sure that there were reasons, sufficient or insufficient: and the knowledge of those reasons would have enabled us to appreciate more fully the state of the Greek mind, in respect to logical theory, in and before the year 300 B.C.
