Repetition: An Essay in Experimental Psychology. with a Bibliographical Essay: How Kierkegaard Got into English

xlii, 212 pp. "Repetition (Danish: Gentagelsen) is an 1843 book by Søren Kierkegaard and published under the pseudonym Constantin Constantius to mirror its titular theme. Constantin investigates whether repetition is possible, and the book includes his experiments and his relation to a nameless patient known only as the Young Man.[1] The Young Man has fallen in love with a girl, proposed marriage, the proposal has been accepted, but now he has changed his mind.[2] Constantin becomes the young man's confidant. Coincidentally, the problem that the Young Man had is the same problem Kierkegaard had with Regine Olsen. He had proposed to her, she had accepted but he had changed his mind. Kierkegaard was accused of "experimenting with the affections of his fiancée".[3]"--Wikipedia
