"We are concerned with the problem of man because he is a being afflicted with contradictions and perplexities, because he is not completely a part of his environment. A good horse, properly cared for, lives as a part of his habitat and is unencumbered by problems. In sharp contrast, man is a problem intrinsically and under all circumstances. To be human is to be a problem, and the problem expresses itself in anguish, in the mental suffering of man. Every human being has at least a vague notion, image, or dream of what humanity ought to be, of how human nature ought to act. The problem of man is occasioned by our coming upon a conflict or contradiction between existence and expectation, between what man is and what is expected of him. It is in anguish that man becomes a problem to himself. What he has long disregarded suddenly erupts in painful awareness".
'Who is Man?' (1963)
