"The absence of any special feeling of good or ill, which is the most ordinary condition of life, is neither indifference, nor good, nor pleasure, but suffering and ill. This alone, even if ills did not exceed goods, nor was greater, would be enough to tip the scales of life and human destiny immeasurably onto the side of unhappiness. When man has no feeling of any particular good or ill, he feels in general the native unhappiness of man, and this is that feeling which is called boredom."
