"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 . . . suffering may well be a human achievement, especially if the suffering grows out of existential frustration. Existential frustration is in itself neither pathological nor 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. It (should be) his task, rather, to pilot the patient through his existential crises . . . To be sure, man's search for meaning may arouse inner tension rather than inner equilibrium. However, precisely such tension is an indispensable prerequisite of mental health. There is nothing in the world, I venture to say, that would so effectively help one to survive even the worst conditions as the knowledge that there is a meaning in one's life. In the Nazi concentration camps . . . those who knew that there was a task waiting for them to fulfill were most apt to survive. I consider it a dangerous misconception of mental hygiene to assume that what man needs in the first place is equilibrium or, as it is called in biology, 'homeostasis,' i.e., a tensionless state. What man actually needs is not a tensionless state but rather the striving and struggling for a worthwhile goal, a freely chosen task. What he needs is not the discharge of tension at any cost but the call of a potential meaning waiting to be fulfilled by him."
