(_ad b_) The error _Hasdrubal_ in place of _Hamilcar_, the name of the brother instead of that of the father, originated from an association which dealt with the Hannibal fantasies of my college years and my dissatisfaction with the conduct of my father towards the “enemies of our people.” I could have continued and recounted how my attitude toward my father was changed by a visit to England, where I made the acquaintance of my half-brother, by a previous marriage of my father. My brother’s oldest son was my age exactly. Thus the age relations were no hindrance to a fantasy which may be stated thus: how much pleasanter it would be had I been born the son of my brother instead of the son of my father! This suppressed fantasy then falsified the text of my book at the point where I broke off the analysis, by forcing me to put the name of the brother for that of the father. (_ad c_) The influence of the memory of this same brother is responsible for my having advanced by a generation the mythological horror of the Greek deities. One of the admonitions of my brother has lingered long in my memory. “Do not forget one thing concerning your conduct in life,” he said: “you belong not to the second but really to the third generation of your father.” Our father had remarried at an advanced age, and was therefore an old man to his children by the second marriage. I commit the error mentioned where I discuss the piety between parents and children. Several times friends and patients have called my attention to the fact that in reporting their dreams or alluding to them in dream analyses, I have related inaccurately the circumstances experienced by us in common. These are also historic errors. On re-examining such individual cases I have found that my recollection of the facts was unreliable only where I had purposely disfigured or concealed something in the analysis. Here again we have _an unobserved error as a substitute for an intentional concealment or repression_. From these errors, which originate from repression, we must sharply distinguish those which are based on actual ignorance. Thus, for example, it was ignorance when on my excursion to Wachau I believed that I had passed the resting-place of the revolutionary leader Fischof. Only the name is common to both places. _Fischof’s Emmersdorf_ is located in Kärnthen. But I did not know any better.
