The question of a theory of analytic change is approached through a consideration of analytic impasse. Impasse is considered in relation to impasse in the analyst, linked to an impasse in some forms of mourning in the analyst. The analyst's impasse is considered in the light of character formation, the relation of analytic vocations to early attachment, and object ties in the analyst leading to problems with omnipotence. Impasse then is tied to various processes and defenses that shape and contribute to the analyst's countertransference. Analytic change is considered then in the context of theories of nonlinear development, models of speech practice, and mutative action. These ideas are explored through case material.
