An instinct of self-preservation is precisely what man does not possess. An “instinct” is an unerring and automatic form of knowledge. A desire is not an instinct. A desire to live does not give you the knowledge required for living. And even man’s desire to live is not automatic . . . Your fear of death is not a love for life and will not give you the knowledge needed to keep it. Man must obtain his knowledge and choose his actions by a process of thinking, which nature will not force him to perform. Man has the power to act as his own destroyer — and that is the way he has acted through most of his history.
Man has no automatic code of survival. He has no automatic course of action, no automatic set of values. His senses do not tell him automatically what is good for him or evil, what will benefit his life or endanger it, what goals he should pursue and what means will achieve them, what values his life depends on, what course of action it requires. His own consciousness has to discover the answers to all these questions — but his consciousness will not function automatically.
