You have a body, but you are a soul or self. Without your body, you could still exist. Your body could be and perhaps is outlasted by the immaterial substance which is your soul or self. Thus the substance dualist. Most substance dualists are Cartesians. The self, they suppose, is essentially conscious: it cannot exist unless it thinks or wills or has experiences. In this paper I sketch out a different form of substance dualism. I suggest that it is not consciousness but another immaterial feature which is essential to the self, a feature in one way analogous to a non-dispositional taste. Each self has moreover a different feature of this general kind. If this is right then simple and straightforward answers are available to some questions which prove troublesome to the Cartesian, consciousness-requiring type of substance dualist. I mean the questions, How can the self exist in dreamless sleep?, What distinguishes two simultaneously existing selves, and What makes a self the same self as a self which exists at some other time?

A systematic study of rational or justified belief, which throws fresh light on current debates about foundations and coherence theories of knowledge, the validation of induction and moral scepticism. Dr Nathan focuses attention on the largely unsatisfiable desires for active and self-conscious assurance of truth liable to be engendered by philosophical reflection about total belief-systems and the sources of knowledge. He extracts a kernel of truth from the doctrine that a regress of justification is both necessary and impossible, contrasts the resultant scepticism with more familiar complaints about the inapplicability of supposedly essential cognitive concepts and explores the feasibility of non-Humean modes of consolation. This is an original and carefully constructed book, which will interest professional philosophers and advanced students of epistemology.

Some people believe that God made it a condition for His forgiveness even of repentant sinners that Jesus died a sacrificial death at human hands. Often, in the New Testament, this doctrine of Objective Atonement seems to be implied, as when Jesus spoke of his blood as ‘shed for many for the remission of sins’ , or when St Paul said that ‘Christ died for our sins according to the scriptures’ . And for many centuries the doctrine was indeed accepted by most if not all Christian theologians. It seems in fact to be an essential part of Christianity, which adherents of that religion cannot reject without undermining the authority both of their scriptures and of a very long tradition. It looks then as if objections to the doctrine are objections to the Christian scheme itself. Here is one of them. As the Gospels present it Jesus was murdered, by one or more of Pilate, the Sanhedrin and the Jewish mob. Given Objective Atonement, God ordained the sacrificial death of Jesus, and so, as it seems, this murder. Murder requires freedom on the killer's part. And many have doubted that an action can be both free and ordained by God. Leave that aside. A good God would in any case not make it a condition for our forgiveness that someone acquired the guilt of murder

When do two mental items belong to the same life? We could be content with the answer -just when they have certain volitional qualities in common. An affinity is noted between that theory and Berkeley's early doctrine of the self. Some rivals of the volitional theory invoke a spiritual or physical owner of mental items. They run a risk either of empty formality or of causal superstition. Other rivals postulate a non-transitive and symmetrical relation in the set of mental items. They must allow in consequence either for joint ownership of one and the same mental item, or for incompatible simultaneous decisions by one and the same person, or for new forms of death. This makes them disquieting. Another rival invokes a transitive and symmetrical relation defined in terms of co-consciousness. Even that allows for incongruous simultaneities. The volitional theory is free from such disadvantages.

In "Warrant and Proper Function" Plantinga argues that atheistic Naturalism is self-defeating. What is the probability that our cognitive faculties are reliable, given this Naturalism and an evolutionary explanation of their origins? Plantinga argues that if the Naturalist is modest enough to believe that it is irrational to have any belief as to the value of this probability, then he is irrational even to believe his own Naturalism. I suggest that Plantinga's argument has a false premise, and that even if his argument were sound there would be reasons for doubting whether the Naturalist should respond to it by abandoning his Naturalism

Beneath metaphysical problems there often lies a conflict between what we want to be true and what we believe to be true. Nathan provides a general account of the resolution of this conflict as a philosophical objective, showing that there are ways of thinking it through systematically with a view to resolving or alleviating it. The author also studies in detail a set of interrelated conflicts about the freedom and the reality of the will. He shows how difficult it is to find a freedom either of decision or of action which is both an object of reflective desire and an object of rational belief. He also examines conflicts about volition as such, contending that the veridicality of volitional experience is no less easy to doubt than the veridicality of our experience of colors. In this context, arguments emerge for a voluntarist theory of the self. Nathan's important book will be essential reading for all philosophers interested in free will, volition, the self, and the methodology of metaphysics
