The wonder with which philosophy begins is first and foremost the cosmic wonder, the wonder which Nature forces on us in its cosmic complexion and in its macroscopic expanse. No doubt the mystery of the starry heavens has compelled man's attention earlier than the riddle of the unfathomable deep surging within. The history of the philosophical inquiry makes it abundantly clear that the reflection on self has no psychological or historical priority. But once philosophic consciousness awakens to the dichotomy of the self and the not-self the accent of philosophic reflection shifts constantly from one sphere to another. The attempt to assimilate the world of Nature to the world of psychic privacy is met with a parallel movement which seeks to reduce the world as experienced from within into the categories of the world as given without. It was the genious of Plato that introduced the concept of a third realm which belongs neither to Nature nor to psychic reality, a world of pure transcendental universals which he called Ideas. But neither the beginnings of early classical European thought nor of Oriental speculation have shown any concern for historical reality. It is true that the concept of perpetual flux dominated the classical antiquity very early but there is a long way from the idea of interminable change to the idea of historical process.
