His object was to discover the laws of the past so as to serve as a light to illumine the future. We must not confuse the recognition of the utility of history with any ideas of a didactic aim. Two points more in Thucydides remain for our consideration: his treatment of the rise of Greek civilisation, and of the primitive condition of Hellas, as well as the question how far can he be said really to have recognised the existence of laws regulating the complex phenomena of life. III THE investigation into the two great problems of the origin of society and the philosophy of history occupies such an important position in the evolution of Greek thought that, to obtain any clear view of the workings of the critical spirit, it will be necessary to trace at some length their rise and scientific development as evinced not merely in the works of historians proper, but also in the philosophical treatises of Plato and Aristotle. The important position which these two great thinkers occupy in the progress of historical criticism can hardly be over-estimated. I do not mean merely as regards their treatment of the Greek Bible, and Plato’s endeavours to purge sacred history of its immorality by the application of ethical canons at the time when Aristotle was beginning to undermine the basis of miracles by his scientific conception of law, but with reference to these two wider questions of the rise of civil institutions and the philosophy of history. And first, as regards the current theories of the primitive condition of society, there was a wide divergence of opinion in Hellenic society, just as there is now. For while the majority of the orthodox public, of whom Hesiod may be taken as the representative, looked back, as a great many of our own day still do, to a fabulous age of innocent happiness, a _bell’ età dell’ auro_, where sin and death were unknown and men and women were like Gods, the foremost men of intellect such as Aristotle and Plato, Æschylus and many of the other poets {29} saw in primitive man ‘a few small sparks of humanity preserved on the tops of mountains after some deluge,’ ‘without an idea of cities, governments or legislation,’ ‘living the lives of wild beasts in sunless caves,’ ‘their only law being the survival of the fittest.’ And this, too, was the opinion of Thucydides, whose _Archæologia_ as it is contains a most valuable disquisition on the early condition of Hellas, which it will be necessary to examine at some length.
