 No one had speculated upon economics. No one had worked out the reaction of one social class upon another. We are too apt to consider the career of Alexander as the crown of some process that had long been afoot; as the climax of a crescendo. In a sense, no doubt, it was that; but much more true is it that it was not so much an end as a beginning; it was the first revelation to the human imagination of the oneness of human affairs. The utmost reach of the thought of Greece before his time was of a Persian empire Hellenized, a predominance in the world of Macedonians and Greeks.

For some generations Alexander the Great was for mankind the symbol and embodiment of world order and world dominion. He became a fabulous being. His head, adorned with the divine symbols of the demi-god Hercules or the god Ammon Ra, appears on the coins of such among his successors as could claim to be his heirs. Then the idea of world dominion was taken up by another great people, a people who for some centuries exhibited considerable political genius, the Romans; and the figure of another conspicuous adventurer, Cæsar, eclipsed for the western half of the old world the figure of Alexander.

We have taken the figures of Herodotus and Aristotle as typical exponents of this first great idea, the idea of science—using the word science in its widest and properest sense, to include
