[Footnote 205: Aristotel. Gener. et Corr. i. 7, p. 323, b. 12. It was the opinion of Demokritus, that there could be no action except where agent and patient were alike.

Many contemporary philosophers affirmed distinctly the opposite. [Greek: To\ o(/moion u(po\ tou= o(moi/ou pa=n a)pathe/s], &c. Diogenes the Apolloniate agreed on this point generally with Demokritus; see above, p. 61, note 1 [*Footnote 185*]. The facility with which these philosophers laid down general maxims is constantly observable.] [Footnote 206: Aristot. Gen. et Corr. i. 2, p. 316, a. 1; Theophrast. De Sensu, s. 63, 64.
