“Not every conflict is necessarily neurotic; some amount of conflict is normal and healthy. In a similar sense suffering is not always a pathological phenomenon; rather than being a symptom of neurosis, suffering may well be a human achievement, especially if the suffering grows out of existential frustration... Existential frustration is neither pathological or pathogenic. A man’s concern, even his despair, over the worthwhileness of life is an existential distress but by no means a mental disease. It may well be that interpreting the first in terms of the latter motivates a doctor to bury his patient’s existential despair under a heap of tranquilizing drugs.”
