Weber, however, is essentially discussing a quality of leadership, and one which is found in contexts other than that of revitalization movements. In consequence, his generalizations do not deal with the revitalization formula it-self, but rather with the nature of the relationship of the early adherents to their prophet. Furthermore, there is a serious ambiguity in Weber’s use of the charisma concept. Weber seems to have been uncertain whether to regard it as an unusual quality in the leader which is recognized and rationalized by his adherents, or whether to regard it as a quality ascribed to the leader by followers and hence as being a quality of their relationship to him, determined both by the observed and the observer in the perceptual transaction. We have used it to denote the libidinal relationship which Freud described in Group Psychology and the Analysis of the Ego (1922).
