“ The neurotic has lost, by his repressions, many sources of mental energy whose contingents would have been very valuable for his character building and his life activities. We know a far more purposive process of development, the socalled sublimation (Sublimirung) , by which the energy of infantile wish-excitations is not secluded, but remains capable of application, while for the particular excitations, instead of becoming useless, a higher, eventually no longer sexual, goal is set up. ”
