In closing this study, which has been carried out in extremely condensed form, I want to state the conclusion that the beginnings of religion, ethics, society, and art meet in the Oedipus complex. This is in entire accord with the findings of psychoanalysis, namely, that the nucleus of all neuroses as far as our present knowledge of them goes is the Oedipus complex. It comes as a great surprise to me that these problems of racial psychology can also be solved through a single concrete instance, such as the relation to the father. Perhaps another psychological problem must be included here. We have so frequently had occasion to show the ambivalence of emotions in its real sense, that is to say the coincidence of love and hate towards the same object, at the root of important cultural formations. We know nothing about the origin of this ambivalence. It may be assumed to be a fundamental phenomenon of our emotional life. But the other possibility seems to me also worthy of consideration: that ambivalence, originally foreign to our emotional life was acquired by mankind from the father complex[226], where psychoanalytic investigation of the individual to-day still reveals the strongest expression of it[227]. Before closing we must take into account that the remarkable convergence reached in these illustrations, pointing to a single inclusive relation, ought not to blind us to the uncertainties of our assumptions and to the difficulties of our conclusions. Of these difficulties I will point out only two which must have forced themselves upon many readers. In the first place it can hardly have escaped any one that we base everything upon the assumption of a psyche of the mass in which psychic processes occur as in the psychic life of the individual. Moreover, we let the sense of guilt for a deed survive for thousands of years, remaining effective in generations which could not have known anything of this deed. We allow an emotional process such as might have arisen among generations of sons that had been ill-treated by their fathers, to continue to new generations which had escaped such treatment by the very removal of the father. These seem indeed to be weighty objections and any other explanation which can avoid such assumptions would seem to merit preference.
