The nature, extent and validity of the modern institution of private ownership remains a major source of contention between libertarian, liberal and socialist positions in political theory. The thesis contributes to current debates by ways of an analysis of historically significant theories of property, viewed in connection with their underlying conceptions of the person. ;The dissertation consists of three parts. Part One is an exposition of J. Locke's natural rights theory, together with Hegel's criticism of it. Chapter One argues that (...) Locke's famous labor theory of property presupposes an essentially "acquisitive" conception of the person. Chapter Two analyzes Hegel's transformation of Locke's basic model within the framework of an argument no longer derived from the paradigm of natural rights; Hegel introduces instead his notion of the historical and cultural achievements of "Geist". Hegel's theory presupposes, we argue, an essentially "purposeful" self. Property is viewed no longer as an incentive to labor, but now primarily as an instrument for the realization of distinctive human capacities. ;Part Two presents Marx's critique of Hegel's conception of ownership. Chapter Three sets forth the early normative critique: in the realm of labor the acquisitive self remains primary in Hegel's theory. Marx, in turn, proposes that the criterion of "care" for the development of human capacities be introduced within the economic realm. Chapter Four argues that his project in the Grundrisse becomes an investigation of the social conditions of the possibility of this new form of ownership. We argue, moreover, that Marx's notion of "communal property" entails a form of Rawl's difference principle, and juxtapose his theory to the utilitarian view of J. S. Mill, on the one hand, and that of Rawls himself, on the other. ;The final part presents the outlines of a new conception of socialist ownership. We conclude that Marx's theory remains utopian given that it lacks an adequate conception of other-directed, socialist motivation. At the same time, we argue that Rawls's scepticism in regard to the possibility of socialist ownership remains unfounded, by way of drawing on yet a third model of personality and labor: that derived from the traditional female realm of child-care. We conclude that Rawls's theory, when taken in conjunction with our analysis of "reproductive labor", presents us with a new conception of socialist property arrangements which is at once highly feasible.
