The conclusion summarizes the ways in which Modal Integrative Psychotherapy (MIP) may be seen as revolutionizing conventional psychotherapy by introducing the idea of “switching modal worlds”, not just within the subjectivity of the client, but also “worlds”, as sets of circumstances described in modal logic, within which subjective experience occurs. Such a shift of emphasis from an essentially subjectivist position to a fundamentally more ambitious conceptual approach to both lived experience and psychotherapy challenges certain conventional norms, including the blurring of the distinction between “reality” and “subjectivity” and the notion of how different experiential worlds might or might not be called into actual experience by the use of MIP technique.
