13. The Value of Life (Pessimism and Optimism)

The fulfillment of a desire brings pleasure and its non-fulfillment brings pain. But from this we must not conclude that pleasure is the satisfaction of a desire, and pain its non-satisfaction. Both pleasure and pain can be experienced without being the consequence of desire. Illness is pain not preceded by desire. If anyone were to maintain that illness is unsatisfied desire for health, he would be making the mistake of regarding the unconscious wish not to fall ill, which we all take for granted, as a positive desire. When someone receives a legacy from a rich relative of whose existence he had not the faintest idea, this fills him with pleasure without any preceding desire.
