” … But powerful as the sexual drive and all its derivations are, they are by no means the most powerful forces within man and their frustration is not the cause of mental disturbance.  The most powerful forces motivating man’s behavior stem from the condition of his existence, the “human situation.”
    Man cannot live statically because his inner contradictions drive him to seek for an equilibrium, for a new harmony instead of the lost harmony with nature.  After he has satisfied his animal needs, he is driven by his human needs. …. All passions and strivings of man are attempts to find an answer to his existence or, as we may also say, they are an attempt to avoid insanity.” – Erich Fromm
