After reviewing the concept of the archetype suggested by Jung in his theory of the unconscious, the Author proposes its clinical application to the interpretation of a dream and a delusional system, adding some considerations on the meaning of the symbols they contain. In particular, he shows how they could have been produced for metaphorical extension by those archetypal experiences that in the evolutionary history of man have accompanied the differentiation of our human needs from those of our animal ancestors.
