“Human existence begins when the lack of fixation of action by instincts exceeds a certain point; when the adaptation to nature loses its coercive character; when the way to act is no longer fixed by hereditarily given mechanisms. In other words, human existence and freedom are from the beginning inseparable. Freedom is here used not in its positive sense of “freedom to” but in its negative sense of “freedom from”, namely freedom from instinctual determination of his actions.”
