Maslow explained that, some time in the late thirties, he had been struck by the thought that modern psychology is based on the study of sick people.… - Colin Wilson

You've got the temperament of a scholar, and you live on your own and write books. You don't have anything to do with civilization. You've been in London a few days and you can't wait to get back home. But how about the people who can't write books -- people there's no outlet for in this civilization? What about your new men who don't know what to do?

Like Fichte, Brentano had one simple and powerful insight. He declared: there is a basic difference between a mental and physical act. if I slip on the snow and fall flat on my back, that is an unintentional physical act. But there is no such thing as an unintentional mental act. When I think, I have to think about something; I have to focus my mind on it. You could compare all mental acts (thinking, willing, loving, trying to remember something) to a searchlight beam stabbing into the darkness. There is an element of will, of 'intentionality,' in all mental activity. So it is quite inaccurate to compare mental activity to chemistry, or to a kind of drifting, like leaves on a stream. It flows purposefully or not at all.

Some years ago, an American psychologist, Abraham Maslow, felt the same kind of instinctive revolt against the 'atmosphere' of Freudian psychology, with its emphasis on sickness and neurosis, and decided that he might obtain some equally interesting results if he studied extremely healthy people. He therefore looked around for the most cheerful and well-adjusted people he could find, and asked for their co-operation in his studies. He soon discovered and interesting fact: that most extremely healthy people frequently experience of intense affirmation and certainty; Maslow called these 'peak experiences.' No one had made this discovery before because it had never struck anyone that a science calling itself 'psychology' and professing to be a science of the human mind (not merely the sick mind), ought to form its estimate of human beings by taking into account healthy minds as well as sick ones. A sick man talks obsessively about his illness; a healthy man never talks about his health; for as Pirandello points out, we take happiness for granted, and only begin to question life when we are unhappy. Hence no psychologist ever made this simple and obvious discovery about peak experiences.
