The latter is the only scientific theory and was apprehended in its fulness by Aristotle, whose application of the inductive method to history, and whose employment of the evolutionary theory of humanity, show that he was conscious that the philosophy of history is nothing separate from the facts of history but is contained in them, and that the rational law of the complex phenomena of life, like the ideal in the world of thought, is to be reached through the facts, not superimposed on them—_κατὰ πολλῶν_ not _παρὰ πολλά_. And finally, in estimating the enormous debt which the science of historical criticism owes to Aristotle, we must not pass over his attitude towards those two great difficulties in the formation of a philosophy of history on which I have touched above. I mean the assertion of extra-natural interference with the normal development of the world and of the incalculable influence exercised by the power of free will. Now, as regards the former, he may be said to have neglected it entirely. The special acts of providence proceeding from God’s immediate government of the world, which Herodotus saw as mighty landmarks in history, would have been to him essentially disturbing elements in that universal reign of law, the extent of whose limitless empire he of all the great thinkers of antiquity was the first explicitly to recognise. Standing aloof from the popular religion as well as from the deeper conceptions of Herodotus and the Tragic School, he no longer thought of God as of one with fair limbs and treacherous face haunting wood and glade, nor would he see in him a jealous judge continually interfering in the world’s history to bring the wicked to punishment and the proud to a fall. God to him was the incarnation of the pure Intellect, a being whose activity was the contemplation of his own perfection, one whom Philosophy might imitate but whom prayers could never move, to the sublime indifference of whose passionless wisdom what were the sons of men, their desires or their sins? While, as regards the other difficulty and the formation of a philosophy of history, the conflict of free will with general laws appears first in Greek thought in the usual theological form in which all great ideas seem to be cradled at their birth. It was such legends as those of Œdipus and Adrastus, exemplifying the struggles of individual humanity against the overpowering force of circumstances and necessity, which gave to the early Greeks those same lessons which we of modern days draw, in somewhat less artistic fashion, from the study of statistics and the laws of physiology.
