Through a marvelous law of natural compensation, he who gives of himself grows, and he who turns inward and lives from small pleasures, is afraid to share them with others, and only thinks avariciously of cultivating his appetites loses his humanity and becomes loneliness itself. He carries in his breast all the dreariness of winter. He becomes in fact and appearance an insect.
