"We are omniscient but confused," says Leibniz. He also says that we live in the best of all possible worlds, yet do not causally interact. So what are we? Leibniz is known for many things, including the ideality of space and time, calculus, plans for a universal language, theodicy, and ecumenism. But he is not known for his ideas on the self and personal identity. This book shows that Leibniz offers an original, internally coherent theory of personal identity, a theory (...) that stands on its own even next to Locke's contemporaneous and more famous version. This book will appeal not only to students of Leibniz's thought but also to philosophers and psychologists interested in methodological problems in understanding or formulating theories of self and personal identity.

Like many other Christian philosophers, past and present, Descartes envisions an "afterlife" for the soul after bodily death. Some, both Christian and non-Christian, including Geach, Strawson and Williams, have argued that the afterlife Descartes envisions is far from the attractive state heaven is supposed to be. Others, including Leibniz, Russier, and Cottingham, have argued that a Cartesian afterlife represents a state of existence that cannot even be rationally desired. But I shall argue in this paper that both criticisms fail to (...) appreciate fully the details of Descartes' doctrine of immortality. (shrink)
