Life as a Pendulum

Schopenhauer likened life to a pendulum swinging between suffering and boredom: when a desire is unsatisfied, one sinks into the suffering of seeking and not attaining; once a desire is satisfied, the suffering recedes for a moment, only to be soon replaced by the emptiness and boredom of "having nothing to do," giving rise in turn to new desire, so that life circles endlessly between these two poles, never at peace — a pessimistic conclusion later partly inherited and fundamentally reversed by Nietzsche (who held that one should actively affirm this eternal craving itself, rather than seek to deny or flee it).
