Richard Swinburne

This paper defends logical nominalism, the thesis that logically necessary truth belongs primarily to sentences and depends solely on the conventions of human language. A sentence is logically necessary iff its negation entails a contradiction. A sentence is a posteriori metaphysically necessary iff it reduces to a logical necessity when we substitute for rigid designators of objects or properties canonical descriptions of the essential properties of those objects or properties. The truth-conditions of necessary sentences are not to be found in any transcendent reality, such as God's thoughts. ‘There is a God’ is neither a priori nor a posteriori metaphysically necessary; God is necessary in the sense that His existence is not causally contingent on anything else.

Christianity, Islam, and Judaism all claim that God has given humans a revelation. Divine revelation may be either of God, or by God of propositional truth. Traditionally Christianity has claimed that the Christian revelation has involved both of these. God revealed himself in his acts in history; for example in the miracles by which he preserved the people of ancient Israel, and above all by becoming incarnate as Jesus Christ, who was crucified and rose from the dead. And God also revealed to us propositional truths by the teaching of Jesus and his church. Some modern theologians have denied that Christianity involves any propositional revelation, but there can be little doubt that from the second century until the eighteenth century, Christians and non-Christians were virtually unanimous in supposing that it claimed to have such a revelation, and so it is worthwhile investigating its traditional claim. This article is concerned with the Christian claim to have a propositional revelation. The first section describes the process by which Christians of past centuries have come to believe that certain propositions have been revealed. The second assesses alternative philosophical accounts of what constitutes a belief that such-and-such propositions have been revealed, being a ‘justified’ belief.

Richard Swinburne is one of the most distinguished philosophers of religion of our day. In this volume, many notable British and American philosophers unite to honor him and to discuss various topics to which he has contributed significantly. These include general topics in the philosophy of religion such as revelation, and faith and reason, and the specifically Christian doctrines of the Trinity, the Incarnation, and atonement. In the spirit of the movement which Swinburne spearheaded, the essays use analytic philosophical methods to examine doctrines in particular religious traditions, expanding upon traditional discussions of theism. As such, this volume represents a field-report on the interaction of philosophy and Christian thought in the English-speaking world. Swinburne has himself contributed an individual and personal Intellectual Autobiography.

Scientific explanation in terms of laws and initial conditions (or better, in terms of objects with powers and liabilities) is contrasted with personal explanation in terms of agents with powers and purposes. In each case the factors involved in explanation may themselves be explained, and infinite regress of explanation is logically possible. There can be no absolute explanation of phenomena, which is explanation in terms of the logically necessary; but there can be ultimate explanation which is explanation in terms of factors which themselves have no explanation. Our normal criteria of explanation suggest that the explanation of the universe lies in the action of God.

Richard Swinburne offers an original treatment of a question at the heart of epistemology: what makes a belief rational, or justified in holding? He maps the rival accounts of philosophers on epistemic justification ("internalist" and "externalist"), arguing that they are really accounts of different concepts. He distinguishes between synchronic justification (justification at a time) and diachronic justification (synchronic justification resulting from adequate investigation)--both internalist and externalist. He also argues that most kinds of justification are worth having because they are indicative of truth; however, it is only justification of internalist kinds that can guide a believer's actions. Swinburne goes on to show the usefulness of the probability calculus in elucidating how empirical evidence makes beliefs probably true.

Part I of Language and Time is a defence of the tensed theory of time, the view that assertions about events happening now or being past or future are irreducible to tenseless assertions about the dates at which events happen or about their occurrence before or after other events. It claims that tensed sentences are not translatable by tenseless sentences, nor do they have the same truth conditions as tenseless sentences. They are reducible in neither of these senses either to tenseless date sentences—e.g. “it is raining today” does not have the same truth conditions as “it is raining on 22 February 1994”; nor to token reflexive sentences—e.g. “it is raining now” does not have the same truth conditions as “it is raining simultaneously with this utterance”. Hence, Smith argues, since evidently some tensed sentences are true, they must express propositions of a different kind from tenseless propositions—viz. tensed propositions.
