When we come to ask why this passion struck roots so deep into the very heart and brain of the Greek nation, we must reject the favourite hypothesis of climate. Climate is, no doubt, powerful to a great extent in determining the complexion of sexual morality; yet, as regards paiderastia, we have abundant proof that nations both of North and South have, according to circumstances quite independent of climatic conditions, been both equally addicted and equally averse to this habit. The Etruscan,[183] the Chinese, the ancient Keltic tribes, the Tartar hordes of Timour Khan, the Persians under Moslem rule--races sunk in the sloth of populous cities, as well as the nomadic children of the Asian steppes, have all acquired a notoriety at least equal to that of the Greeks. The only difference between these people and the Greeks in respect to paiderastia is that everything which the Greek genius touched acquired a portion of its distinction, so that what in semi-barbarous society may be ignored as vice, in Greece demands attention as a phase of the spiritual life of a world-historic nation. Like climate, ethnology must also be eliminated. It is only a superficial philosophy of history which is satisfied with the nomenclature of Semitic, Aryan, and so forth; which imagines that something is gained for the explanation of a complex psychological problem when hereditary affinities have been demonstrated. The deeps of national personality are far more abysmal than this. Granting that climate and descent are elements of great importance, the religious and moral principles, the æsthetic apprehensions, and the customs which determine the character of a race, leave always something still to be analysed. In dealing with Greek paiderastia, we are far more likely to reach a probable solution if we confine our attention to the specific social conditions which fostered the growth of this passion in Greece, and to the general habit of mind which permitted its evolution out of the common stuff of humanity, than if we dilate at ease upon the climate of the Ægean, or discuss the ethnical complexion of the Hellenic stock. In other words, it was the Pagan view of human life and duty which gave scope to paiderastia, while certain special Greek customs aided its development.
