On the other hand, the results of Melanie Klein's direct researches into the minds of very young children, whilst underlining the theoretical value of the concept of the super-ego, and deepening our sense of its enormous dynamic power, have nevertheless increased certain of the theoretical difficulties attaching to the first modes of statement of its origin, of its relation to the Œdipus complex, and the developmental phases of the libido. To my mind, the most illuminating suggestion which has yet been offered on these tangled issues is that made by Jones (elaborating a hint of Freud's), when he says that privation is equivalent to frustration3. He further remarks, " . . . guilt, and with it the super-ego, is as it were artificially built up for the purpose of protecting the child from the stress of privation, i.e. of ungratified libido, and so warding off the dread of aphanisis that always goes with this; it does so, of course, by damping down the wishes that are not destined to be gratified. I even think that the external disapproval, to which the whole of this process used to be ascribed,
is largely an affair of exploitation on the child's part; that is to say, non-gratification primarily means danger, and the child projects this into the outer world, as it does with all internal dangers, and then makes use of any disapproval that comes to meet it there (moralisches Entgegenkommen) to signalize the danger and to help it in constructing a barrier against this".
