As a comment on this text there follow a number of essays in "experimental psychology," supposed to be the fruit of the æsthete's (A's) leisure. In them the æsthetic life is exhibited in its various manifestations, in "terms of existence," especially as to its "erotic stages," from the indefinite longings of the Page to the fully conscious "sensual genius" of Don Juan--the examples are taken from Mozart's opera of this name, which was Kierkegaard's favorite--until the whole culminates in the famous "Diary of the Seducer," containing elements of the author's own engagement, poetically disguised--a seducer, by the way, of an infinitely reflective kind. Following this climax of unrestrained æstheticism we hear in the second part the stern demands of the ethical life. Its spokesman, Judge William, rises in defense of the social institutes, and of marriage in particular, against the slurs cast on them by his young friend A. He makes it clear that the only possible outcome of the æsthetic life, with its aimlessness, its superciliousness, its vague possibilities, is a feeling of vanity and vexation of spirit, and a hatred of life itself: despair. One floundering in this inevitable slough of despond, who earnestly wishes to escape from it and to save himself from the ultimate destruction of his personality, must choose and determine to rise into the ethical sphere. That is, he must elect a definite calling, no matter how humdrum, marry, if possible, and thus subject himself to the "general law." In a word, instead of a world of vague possibilities, however attractive, he must choose the definite circumscription of the individual who is a member of society. Only thus will he obtain a balance in his life between the demands of his personality on the one hand, and of the demands of society on him. When thus reconciled to his environment--his "lot"--all the pleasures of the æsthetic sphere which he resigned will be his again in rich measure, but in a transfigured sense.
