It is a matter of fact that love represents an indispensable function in the development of the personality. It is true for the peculiar relation arising out of human contact as well as for the critical processes which passion evokes in our psychic life. The importance of this function has increased concomitantly with our constantly growing consciousness. Analytical psychology has occupied itself at various times with the problem of the development of the personality through love—in a certain sense we might say that this is one of its basic ideas. It is therefore all the more remarkable that the literature offers nowhere a clear expression of this idea. In any event the decisive conclusions to be drawn from the assumption of this conception have never been formulated, much less accepted.
