"But sooner or later, as though by magic, joy and calm would suddenly desert him; all flat plump illusions, all his self-satisfaction and self-importance, and idle peace of mind fell away. Something plunged him into solitude and brooding, made him contemplate suffering and death, the vanity of all undertaking, as he stared into the abyss. At other times a sudden joy blossomed from the hopeless depth of uselessness and horror, a violent infatuation, the desire to sing a beautiful song, or draw. He had only to smell a flower or play with a cat, and his childlike agreement with life came back to him. This time, too, it would come back. Tomorrow or the day after, the world would be good again, it would be wonderful. At least it was so until the sadness returned, the brooding, the remorse for dying fish and wilting flowers, the horror of insensitive, piglike, staring-but-not-seeing human existence."
Narcissus and Goldmund
