"This work appeared originally in 1925 in volume IV. of Die medizin der gegenwart in selbstdarstellungen (Leipzig: Felix Meiner) ... The present translation was first published in the United States in 1927 (New York: Brentano) together with another of Professor Freud's writings, The problem of lay-analyses, translated by another hand. Both the outer cover and the title-page of that volume, which is now out of print, bore only the title of this latter work."--Translator's note.
