Fundamentally, Sartre believes humankind cannot escape responsibility by adopting an external moral system, as the adoption of such is in itself a choice that we endorse, implicitly or explicitly, for which we must take full responsibility. Sartre argues that one cannot escape this responsibility, as each attempt to part one's self from the freedom of choice is in itself a demonstration of choice, and choice is dependent on a person's wills and desires. He states "I am responsible for my very desire of fleeing responsibilities."
