We shall soon find means to justify the nonsense of this dream. Mr. M., with whom I became acquainted _at a dinner-party_, had recently requested me to examine his brother, who showed signs of _paralytic insanity_. The conjecture was right; the painful thing about this visit was that the patient exposed his brother by alluding to his youthful pranks when there was no occasion in the conversation for his doing so. I had asked the patient to tell me the year of his birth, and had got him to make several small calculations in order to bring out the weakness of his memory—all of which tests he passed fairly well. I see now that I am acting like a paralytic in the dream (_I do not know exactly what year it is at present_). Other subject-matter in the dream is drawn from another recent source. The editor of a medical journal, a friend of mine, had accepted for his paper a very unfavourable, a “_crushing_,” criticism of the last book of my friend Fl. of Berlin, the author of which was a very _youthful_ reviewer, who was not very competent to pass judgment. I thought I had a right to interfere, and called the editor to account; he keenly regretted the acceptance of the criticism, but would not promise redress. Thereupon I broke off relations with the journal, and in my letter of resignation expressed the hope that _our personal relations would not suffer from the incident_. The third source of this dream is an account given by a female patient—it was fresh in my memory at the time—of the mental disease of her brother who had fallen into a frenzy, crying “Nature, Nature.” The physicians in attendance thought that the cry was derived from a reading of Goethe’s beautiful _essay_, and that it pointed to overwork in the patient in the study of natural philosophy. I thought rather of the sexual sense in which even less cultured people with us use the word “Nature,” and the fact that the unfortunate man later mutilated his genitals seemed to show that I was not far wrong. Eighteen years was the age of this patient at the time when the attack of frenzy occurred.
