The aim of this paper is to illustrate how the theory of multiple realities, suggested by William James, and then taken up by Alfred Schütz, can contribute to the introduction of a new concept of reality in the contemporary philosophical panorama, in focusing on multiplicity and plurality, and in underlining how the ethical-political implications of this concept allow the recognition of difference and diversity.
