Victor Frankl:
Questing for a meaning to life…questioning, doubting…is rather a human achievement than a neurotic symptom. No animal will ever raise the question of whether or not its existence has a meaning. But man does – and even more, it’s a privilege, a prerogative of YOU – boldly daring adventure to challenge that there IS a meaning to life rather than taking it for granted. In other words, it’s an intellectual honesty and sincerity, but no neurotic disease.
