Going beyond the present controversy surrounding personhood in various non-philosophical contexts, this book seeks to defend the renewed philosophical interest in issues connected with this topic and the need for a more credible philosophical conception of the person. Taking the theory of John Locke as a starting point and in dialogue with contemporary philosophers such as Derek Parfit and P.F. Strawson, the authors develop an original philosophical anthropology based on the writings of Charles Hartshorne and A.N. Whitehead. The authors then show the implications for ethics of this conception of the person and the self.
