Now, like all wide generalities, this statement is at least inaccurate. The prayer of Plato’s ideal City—_ἐξ ἀγαθῶν ἀμείνους_, _καὶ ἐξ ὠφελιμῶν ὠφελιμωτέρους ἀεὶ τοὺς ἐκγόνους γίγνεσθαι_, might be written as a text over the door of the last Temple to Humanity raised by the disciples of Fourier and Saint-Simon, but it is certainly true that their ideal principle was order and permanence, not indefinite progress. For, setting aside the artistic prejudices which would have led the Greeks to reject this idea of unlimited improvement, we may note that the modern conception of progress rests partly on the new enthusiasm and worship of humanity, partly on the splendid hopes of material improvements in civilisation which applied science has held out to us, two influences from which ancient Greek thought seems to have been strangely free. For the Greeks marred the perfect humanism of the great men whom they worshipped, by imputing to them divinity and its supernatural powers; while their science was eminently speculative and often almost mystic in its character, aiming at culture and not utility, at higher spirituality and more intense reverence for law, rather than at the increased facilities of locomotion and the cheap production of common things about which our modern scientific school ceases not to boast. And lastly, and perhaps chiefly, we must remember that the ‘plague spot of all Greek states,’ as one of their own writers has called it, was the terrible insecurity to life and property which resulted from the factions and revolutions which ceased not to trouble Greece at all times, raising a spirit of fanaticism such as religion raised in the middle ages of Europe. These considerations, then, will enable us to understand first how it was that, radical and unscrupulous reformers as the Greek political theorists were, yet, their end once attained, no modern conservatives raised such outcry against the slightest innovation. Even acknowledged improvements in such things as the games of children or the modes of music were regarded by them with feelings of extreme apprehension as the herald of the _drapeau rouge_ of reform. And secondly, it will show us how it was that Polybius found his ideal in the commonwealth of Rome, and Aristotle, like Mr. Bright, in the middle classes. Polybius, however, is not content merely with pointing out his ideal state, but enters at considerable length into the question of those general laws whose consideration forms the chief essential of the philosophy of history.
