The manner in which the candidate works through the specific characteristic of a didactic analysis,–the identifying with the 'professional activity' of the analyst,—is the determining factor in his success as an analyst. Working by identification at first is necessary in all candidates but the degree to which it can be supplanted by the use of sublimation determines the success of the analysis. In some instances this push toward a sublimation beyond the candidate's capacity can be a professional hazard. Windholz discusses in detail the need of at times admitting failure, acknowledging 'humaneness'. However, doing so introduces complications, including the analyst's alleviation of his own guilt. Greater knowledge of the dynamics of the specific sublimations necessary for analytic work should help in the selection of candidates. Identification with the analyst in his work (with his 'neutral attitude' in interpretations) plays a role in the 'ego transformations' of the candidate, and increases the capacity of his ego to tolerate derivatives of unconscious impulses in himself and in his patients.
