" Accordingly, identification, or the formation of composite figures, serves different purposes: first, to represent a feature both persons have in common; secondly, to represent a displaced common feature; but thirdly, to find expression for a common feature that is merely wished for. Since wishing it to be the case that two people have something in common is often the same as exchanging them, this relation too is expressed in the dream by identification. In the dream of Irma's injection, I wish to exchange this patient for another, that is, I wish that the other were my patient, as Irma is; the dream takes account of the wish in showing me a figure who is called Irma, but who is examined in a posture in which I have only had occasion to see the other.

" Hence, it is quite conceivable that even the sense of guilt engendered by civilization is not recognized as such, but remains for the most part unconscious, or manifests itself as an unease, a discontent, for which other motivations are sought. The religions, at least, have never ignored the part that a sense of guilt plays in civilization. Moreover - a point I failed to appreciate earlier - they claim to redeem humanity from this sense of guilt, which they call sin. From the way in which this redemption is achieved in Christianity - through the sacrificial death of one man, who thereby takes upon himself the guilt shared by all - we drew an inference as to what may have been the original occasion for our acquiring this primordial guilt, which also marked the beginning of civilization.
