The uroboric tendency of the unconscious to reabsorb all its products by destroying them so as to give them back in new, changed form is repeated on the higher plane of ego consciousness.  Here, too, the analytical process precedes the synthesis, and differentiation is the prime requisite for a later integration.\n\n 'In this sense all knowledge rests on an aggressive act of incorporation.  The psychic system, and to an even greater extent consciousness itself, is an organ for breaking up, digesting, and then rebuilding the objects of the world and the unconscious, in exactly the same way as our bodily digestive system decomposes matter physiochemically and uses it for the creation of new structures.
