This book interprets Max Stirner's The Ego and Its Own as a critique of modernity and traces the basic elements of his dialectical egoism through the writings of Benjamin Tucker, James L. Walker, and Dora Marsden. Stirner's concept of 'ownness' is the basis of his critique of the dispossession and homogenization of individuals in modernity and is an important contribution to the research literature on libertarianism, dialectics, and post-modernism.
