The analytical literature concerning the defence mechanism of projection is critically analysed. This defence is examined with reference to the traditional developmental stages of Freudian theory. Projection is differentiated from parallel phenomena such as externalization and self-generalization. The paranoia-homosexuality complex is analysed in detail, with particular attention given to the implications for the aetiology of projection. Alternate explanations for the syndrome are considered and the respective implications for the dynamics of projection are explored. Melanie Klein's hypothesized developmental stages are examined and shown to yield a conceptualization of projection as a regression to developmental antecedent stages. The status of projection as a defence mechanism is then examined, particularly its psychic domain and its role in normal behaviour. The genesis of the superego and of the identification process are discussed. Various neuroses and some psychotic

conditions are also examined for their relationship to projection.
