The Biological Basis of Individuality

Professor Julian S. Huxley

The problem of individuality, physical and mental, is one which obviously has great interest for philosophy. The unity and continuity of the ordinary human consciousness—the “ ego,” the “personality—give us the concrete standard by which we ordinarily judge other systems which have tended towards individuation. A comparative and evolutionary study of biological data, however, will provide us with many facts which throw a new light on the problem. They are often puzzling, but must be taken into account.
