This is not the place to estimate Alexander as an historic personage. What can be ascribed in Alexander’s education to Aristotle’s philosophic instruction is the fact that what was natural to him, the inherent greatness of his mental disposition, acquired inward freedom also, and became elevated into the perfect, self-conscious independence which we see in his aims and deeds. Alexander attained to that perfect certainty of himself which the infinite boldness of thought alone gives, and to an independence of particular and limited projects, as also to their elevation into the entirely universal end of bringing about in the world a social life and intercourse of a mutual kind, through the foundation of states which were free from contingent individuality. Alexander thus carried out the plan which his father had already conceived, which was, at the head of the Greeks, to avenge Europe upon Asia, and to subject Asia to Greece; so that as it was in the beginning of Greek history that the Greeks were united, and that only for the Trojan war, this union likewise brought the Greek world proper to an end. Alexander thereby also avenged the faithlessness and cruelty perpetrated by the Persians on Aristotle’s friend Hermias. But Alexander further disseminated Greek culture over Asia, in order to elevate into a Greek world this wild medley of utter barbarism, bent solely on destruction, and torn by internal dissensions, these lands entirely sunk in indolence, negation, and spiritual degeneracy. And if it be said that he was merely a conqueror who was unable to establish an enduring kingdom, because his kingdom at his death once more fell to pieces, we must acknowledge that, from a superficial view of the case, this is true, as his family did not retain their rule; Greek rule was, however, maintained. Thus Alexander did not found an extensive kingdom for his family, but he founded a kingdom of the Greek nation over Asia; for Greek culture and science have since his time taken root there. The Greek kingdoms of Asia Minor, and particularly of Egypt, were for centuries the home of science; and their influence may have extended as far as to India and to China. We certainly do not know definitely whether the Indians may not have obtained what is best in their sciences in this way, but it is probable that at least the more exact portion of Indian astronomy came to them from Greece. For it was from the Syrian kingdom, stretching into Asia Minor as far as to a Greek kingdom in Bactria, that there was doubtless conveyed to the interior of India and China, by means of Greek colonies migrating thither, the meagre scientific knowledge which has lingered there like a tradition, though it has never flourished. For the Chinese, for example, are not skilful enough to make a calendar of their own, or to think for themselves. Yet they exhibited ancient instruments unsuited to any work done by them, and the immediate conjecture was that these had come from Bactria. The high idea that men had of the sciences of the Indians and of the Chinese hence is false.
