THREE:Again, I think that Zeller quite misconceives the relation between Greek philosophy and Greek life when he attributes the intellectual decline of the post-Aristotelian period, in part at least, to the simultaneous ruin of public spirit and political independence. The degeneracy of poetry and art, of eloquence and history, may perhaps be accounted for in this way, but not the relaxation of philosophical activity. On the contrary, the disappearance of political interests was of all conditions the most favourable to speculation, as witness the Ionians, Democritus, and Aristotle. Had the independence and power of the great city-republics been prolonged much further, it is probableas the example of the Sophists and Socrates seems to showthat philosophy would have becomexi still more absorbingly moral and practical than it actually became in the Stoic, Epicurean, and Sceptical schools. And theoretical studies did, in fact, receive a great impulse from the Macedonian conquest, a large fund of intellectual energy being diverted from public affairs to the pursuit of knowledge, only it took the direction of positive science rather than of general speculation.2Leaving out the matter of a positive relative movement between shafts, which belts as a means of transmitting power cannot insure, there are the following conditions that must be considered in determining whether belts or other means should be employed in transmitting power from one machine to another or between the parts of machines.
