This article describes and elaborates upon the theoretical model of the Mattering Map, initially introduced in Engendered Lives: A New Psychology of Women’s Experience (Kaschak, 1992). This model organizes the principles of contextual feminist theory and practice in a manner that honors the complexity, multiplicity, and morphing of the energetic field of mattering. The mattering map is more intimately related to 21st century physics, neuroscience, and constructionist thought than to the reductionist and fragmenting epistemological models of the 19th and 20th centuries.
