Psychology and Cosmopolity

According to what, for at least centuries, has been the predominant Psychological theory, the principle of all individual behavior is personal survival.  On that basis, as Hobbes influentially draws out, the existence of others, and a Species-drive, can only be conceived as radically transcendent to, if not antagonistic to, one.  But, within the past two centuries, that principle has been challenged in two ways, though not yet effectively enough to supplant in the popular imagination.  First, the Will to Power and Evolution, in themselves, entail more than mere survival, i. e. growth, in some respect.  Second, Darwinism, especially, suggests that individual behavior can, in fact, be a manifestation of a Species-drive, as it more patently is in Reproductive processes.  On that basis, immanent in even the most mundane bit of personal behavior can be, contrary to traditional Psychology, the promotion of a Cosmopolity that, millennia after the origin of the Species, is now becoming a concrete reality.
