The author examines the problem of ego movement in the light of his linguistic definition of the ego as 'I'. Concluding that 'I move', and that the current psychoanalytic ego cannot move if defined in terms of functions and structures, he reviews the psychological concept of movement. He then presents a classification of movement. Out of this comes a definition of movement as a change in relationship between two objects, the ego usually being identified with one of these, the self. The identification of the ego with the self is called primary identification. This identification does not involve movement. Primary identification may be subdivided into three types: simple, introjective, and divided. These are exemplified. Besides primary identification there is perceptual identification which does involve ego movement. The paper concludes with a brief note on imitation as a form of identification.
