In the course of evolution nature has gone to endless trouble to see that every individual is unlike every other individual. We reproduce our kind by bringing the father's genes into contact with the mother's. These hereditary factors may be combined in an almost infinite number of ways. Physically and mentally, each one of us is unique. Any culture which, in the interests of efficiency or in the name of some political or religious dogma, seeks to standardize the human individual, commits an outrage against man's biological nature.
