"Surely you'll agree that the planets order and control our destinies?" "They do not." "Not at all?" "No." "Then what does? Control our destinies, I mean." "The only external forces that have any influence on us are those we can see every day: the smile, the frown, the fist, the brick wall. What you call 'destiny' is merely a semantic fallacy, the attribution of purpose to blind causality. Insofar as any of us are compelled to resist the flow of random events, we are driven solely by internal drives and forces."
