“I think every well-adjusted human being has dealt squarely with his or her own depravity.”

"Personality Problems and Personality Growth", an essay in, The Self : Explorations in Personal Growth (1956) by Clark E. Moustakas, p. 237, later published in Notes Toward A Psychology of Being (1962).
1940s-1960s
Context: I am deliberately rejecting our present easy distinction between sickness and health, at least as far as surface symptoms are concerned. Does sickness mean having symptoms? I maintain now that sickness might consist of not having symptoms when you should. Does health mean being symptom-free? I deny it. Which of the Nazis at Auschwitz or Dachau were healthy? Those with a stricken conscience or those with a nice, clear, happy conscience? Was it possible for a profoundly human person not to feel conflict, suffering, depression, rage, etc.?
In a word if you tell me you have a personality problem, I am not certain until I know you better whether to say "Good" or "I'm sorry". It depends on the reasons. And these, it seems, may be bad reasons, or they may be good reasons.
An example is the changing attitude of psychologists toward popularity, toward adjustment, even toward delinquency. Popular with whom? Perhaps it is better for a youngster to be unpopular with the neighboring snobs or with the local country club set. Adjusted to what? To a bad culture? To a dominating parent? What shall we think of a well-adjusted slave? A well-adjusted prisoner? Even the behavior problem boy is being looked upon with new tolerance. Why is he delinquent? Most often it is for sick reasons. But occasionally it is for good reasons and the boy is simply resisting exploitation, domination, neglect, contempt, and trampling upon. Clearly what will be called personality problems depends on who is doing the calling. The slave owner? The dictator? The patriarchal father? The husband who wants his wife to remain a child? It seems quite clear that personality problems may sometimes be loud protests against the crushing of one's psychological bones, of one's true inner nature.

Sermon (1899)

The Paris Review interview
Context: I think it’s the shock of every writer’s life when their first book is published. The shock of their lives. One has somehow to adjust from being anonymous, a figure in ambush, working from concealment, to being and working in full public view. It had an enormous effect on me. My impression was that I had suddenly walked into a wall of heavy hostile fire. <!-- That first year I wrote verses with three magical assonances to the line with the intention of abolishing certain critics! Now I read those reviews and they seem quite good. So it was writer’s paranoia. The shock to a person who’s never been named in public of being mentioned in newspapers can be absolutely traumatic. To everybody else it looks fairly harmless, even enviable. What I can see was that it enormously accelerated my determination to bring my whole operation into my own terms, to make my own form of writing and to abandon a lot of more casual paths that I might have followed. If I’d remained completely unknown, a writer not commented on, I think I might have gone off in all kinds of other directions. One can never be sure, of course.
