The projection of unconscious hostility upon demons in the taboo of the dead is only a single example from a whole series of processes to which we must grant the greatest influence in the formation of primitive psychic life. In the foregoing case the mechanism of projection is used to settle an emotional conflict; it serves the same purpose in a large number of psychic situations which lead to neuroses. But projection is not specially created for the purpose of defence, it also comes into being where there are no conflicts. The projection of inner perceptions to the outside is a primitive mechanism which, for instance, also influences our sense-perceptions, so that it normally has the greatest share in shaping our outer world. Under conditions that have not yet been sufficiently determined even inner perceptions of ideational and emotional processes are projected outwardly, like sense perceptions, and are used to shape the outer world, whereas they ought to remain in the inner world. This is perhaps genetically connected with the fact that the function of attention was originally directed not towards the inner world, but to the stimuli streaming in from the outer world, and only received reports of pleasure and pain from the endopsychic processes. Only with the development of the language of abstract thought through the association of sensory remnants of word representations with inner processes, did the latter gradually become capable of perception. Before this took place primitive man had developed a picture of the outer world through the outward projection of inner perceptions, which we, with our reinforced conscious perception, must now translate back into psychology. The projection of their own evil impulses upon demons is only a part of what has become the world system (‘Weltanschauung’) of primitive man which we shall discuss later as ‘animism’. We shall then have to ascertain the psychological nature of such a system formation and the points of support which we shall find in the analysis of these system formations will again bring us face to face with the neurosis. For the present we merely wish to suggest that the ‘secondary elaboration’ of the dream content is the prototype of all these system formations[84]. And let us not forget that beginning at the stage of system formation there are two origins for every act judged by consciousness, namely the systematic, and the real but unconscious origin[85].
