The perversions are initially defined as sexual behaviours which in our culture are generally regarded as corrupt, fearful, and forbidden. The effect of this attitude upon the way they are handled in analysis is considered, and the work of the late German psychoanalyst, Fritz Morgenthaler, is cited as presenting a way of integrating the perversions into analytic treatment. Two cases are cited from the literature which demonstrate both the validity of Morgenthaler's approach and the necessity of moving beyond it. Jungian psychological concepts provide the machinery for doing this. The combination of Morgenthaler's and Jung's ideas suggests a way of dealing with perversions in analysis, of which the author is currently making use in several cases, which are then summarised.
