The problem is that sex is the most dangerous way of trying to achieve personal growth, because the life force has mixed it so liberally with a strin… - Colin Wilson

The basic paradox about sex is that it always seems to be offering more than it can deliver. A glimpse of a girl undressing through a lighted bedroom window induces a vision of ecstatic delight, but in the actual process of persuading the girl into bed, the vision somehow evaporates.

The progress of human knowledge depends on maintaining that touch of scepticism even about the most "unquestionable" truths. A century ago, Darwin's theory of evolution by natural selection was regarded as scientifically unshakeable; today, most biologists have their reservations about it. Fifty years ago, Freud's sexual theory of neurosis was accepted by most psychiatrists; today, it is widely recognized that his methods were highly questionable. At the turn of this century, a scientist who questioned Newton's theory of gravity would have been regarded as insane; twenty years later, it had been supplanted by Einstein's theory, although, significantly, few people actually understood it. It seems perfectly conceivable that our descendants of the twenty-second century will wonder how any of us could have been stupid enough to have been taken in by Darwin, Freud or Einstein.

I began with a strong bias toward skepticism. Besides, to tell the truth, I still find occult phenomena a little preposterous and irrelevant. What do they really matter if you place them against the truly great human achievements — against the creative genius of a Michaelangelo, a Beethoven, an Einstein? In that context they seem almost trivial.
