"I must also call your attention to the fact that it is crucial for my viewpoint that human behavior is to a large extent charged with a considerable amount of energy, but that in contrast to Freud I do not consider this energy to be sexual, but the vital energy within any organism which, according to biological laws, gives man the desire to live, and that means to adapt himself to the social necessities of his society. To go back to what I consider to be the misunderstanding, it has never been my position that society only deforms or manifests that which is already there. If we make the distinction between human necessities in general and human desires in particular then indeed, society creates particular desires which, however, follow the general laws of the necessities rooted in human nature."
