456Is Moral Relativism Consistent?Analysis 45 (1): 40-44. 1985.Let C1 and C2 be distinct moral codes formulated in English. Let C1 contain a norm N and C2 its negation. The paper construes the moral relativist as saying that if both codes are consistent, then, in the strongest sense of correctness applicable to moral norms, they are also both correct in the sense that they contain only correct moral norms. If we believe that the physical statements of English are true (false) in English, we will reject an analogous statement made of physical theories. We wi…Read more

276The structure of type theoryJournal of Philosophy 77 (5): 241-259. 1980.Formal principals are isolated to reveal a structure embedded in a wide range of studies, each of which partitions a domain of individuals into types and categories. It is thought that any reasonable theory of types should include these principles.

109Can a language have indenumerably many expressions?History and Philosophy of Logic 4 (1-2): 73-82. 1983.A common assumption among philosophers is that every language has at most denumerably many expressions. This assumption plays a prominent role in many philosophical arguments. Recently formal systems with indenumerably many elements have been developed. These systems are similar to the more familiar denumerable first-order languages. This similarity makes it appear that the assumption is false. We argue that the assumption is true

650Semantical Hierarchies and Semantical PrimitivesIn Hassan Sharifi (ed.), From Meaning to Sound: Proceedings of the 1974 Mid-American Linguistics Conference, 5: 38-40., College of Arts and Sciences, University of Nebraska. 1975.Quine’s way of dealing with the semantical paradoxes (Ways of Paradox, pp. 9-10) is criticized. The criticism is based on three premises: (1) no learnable language has infinitely many semantical primitives; (2) any language of which Quine’s theory is true has infinitely many semantical primitives; (3) English is a learnable language. The conclusion drawn is that Quine’s theory is not true of English.

87Is Any Economic System Unjust?Southwest Philosophy Review 5 (2): 17-23. 1989.The morality of an economic system characterized as an Adam Smith type system is compared with one characterized by central planning. A prima facie case is made that, while the latter has attributes that satisfy a necessary condition for having moral attributes, the former does not and, as a result, has no moral attributes. But then a deeper look at the situation reveals that the directed systems really do not satisfy the necessary condition either. Both the directed and undirected systems end u…Read more

122Understanding sentencesPhilosophical Investigations 23 (1). 2000.Doubts are raised about the claim that on mastering a finite vocabulary and a finitely stated set of rules we are prepared to understand a potential infinitude of sentences. One doubt is about understanding a potential infinitude of sentences. A second doubt is about the assumption that understanding a sentence must be a matter of figuring out its meaning from an antecedent knowledge of the meaning of its words and applying rules.

121Theories of truth and semantical primitivesJournal of Philosophical Logic 6 (1). 1977.Robert cummins has recently attacked this line of argument: if p is a semantically primitive predicate of a first order language l, then p requires its own clause in the definition of satisfaction integral to a definition of truth of l. thus if l has infinitely many such p, the satisfaction clause cannot be completed and truth for l will remain undefined. against this cummins argues that a single clause in a general base theory for l can specify satisfaction conditions for even infinitely many s…Read more

85Definite Descriptions, Negation, and NecessitationRussell: The Journal of Bertrand Russell Studies 13 (1): 36-47. 1993.The principal question asked in this paper is: in the case of attributive usage, is the definite description to be analyzed as Russell said or is it to be treated as a referring expression, functioning semantically as a proper name? It answers by defending the former alternative.

881Domains of DiscourseLogique Et Analyse 117 (17): 173-176. 1987.Suppose there is a domain of discourse of English, then everything of which any predicate is true is a member of that domain. If English has a domain of discourse, then, since ‘is a domain of discourse of English’ is itself a predicate of English and true of that domain, that domain is a member of itself. But nothing is a member of itself. Thus English has no domain of discourse. We defend this argument and go on to argue to the same conclusion without relying on the supposition that English is …Read more

102Steiner versus Wittgenstein: Remarks on Differing Views of Mathematical TruthTheoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 20 (3): 347-352. 2010.Mark Steiner criticizes some remarks Wittgenstein makes about Gödel. Steiner takes Wittgenstein to be disputing a mathematical result. The paper argues that Wittgenstein does no such thing. The contrast between the realist and the demonstrativist concerning mathematical truth is examined. Wittgenstein is held to side with neither camp. Rather, his point is that a realist argument is inconclusive.

137Two concepts of truthPhilosophical Studies 70 (1). 1993.In this paper the authors recapitulate, justify, and defend against criticism the extension of the redundancy theory of truth to cover a wide range of uses of ‘true’ and ‘false’. In this they are guided by the work of A. N. Prior. They argue Prior was right about the scope and limits of the redundancy theory and that the line he drew between those uses of ‘true’ which are and are not susceptible to treatment via redundancy serves to distinguish two important and mutually irreducible types of tru…Read more

745Applying the concept of painIyyun 52 (July): 290-300. 2003.This paper reaches the conclusion that, while there are ordinary cases in which the pretending possibility is reasonable, these cases always contain some element that makes it reasonable. This will be the element we ask for when we ask why pretending possibility is raised. Knowledge that someone else is in pain is a matter of eliminating the proposed element or neutralizing its pain-negating aspect.

254Quantifying over the realsSynthese 101 (1). 1994.Peter Geach proposed a substitutional construal of quantification over thirty years ago. It is not standardly substitutional since it is not tied to those substitution instances currently available to us; rather, it is pegged to possible substitution instances. We argue that (i) quantification over the real numbers can be construed substitutionally following Geach's idea; (ii) a price to be paid, if it is that, is intuitionism; (iii) quantification, thus conceived, does not in itself relieve us …Read more

16Austin and perceptionActa Analytica 16 (27): 169-193. 2001.Some of Austin's general statements about the doctrines of sense-datum philosophy are reviewed. It is concluded that Austin thought that in these doctrines "directly see" is given a new but inadequately explained and defined use. Were this so, the philosophical use of "directly see" would lack a definite sense and this would correspondingly affect the doctrines. They would lack definite truth-value. Against this, it is argued that the philosopher's use of "directly see" does not support Austin's…Read more

78Do we need models?Notre Dame Journal of Formal Logic 28 (3): 414-422. 1987.The aim of this paper is to provide a nondenotational semantics for first-order languages which will match one for one each distribution of truth-values available in terms of a denotational semantics.

625What Truth is there in Psychological Egoism?Facta Philosophica 8 (1-2): 145-159. 2006.Psychological egoism says that a purposive action is self-interested in a certain sense. The trick is to say in what sense. On the one hand, the psychological egoist wants to avoid a thesis that can be falsified by trivial examples. On the other hand, what is wanted is a thesis that lacks vacuity. The paper’s purpose is to arrive at such a thesis and show that it is a reasonable guess with empirical content.

96Minds, substances, and capacitiesPhilosophy and Phenomenological Research 44 (2): 213-225. 1983.This paper pushes to the claim that the following is Descartes’s fundamental thesis: something has self-presenting states and self-presenting states only. Were he to have established this he would have revamped our worldview in essentially the manner he wished to revamp it. From this proposition one can get an argument for the substance view of the mind in Descartes’s writings.

124This book says Prior claims: (1) that a sentence never names; (2) what a sentence says cannot be otherwise signified; and (3) that a sentence says what it says whatever the type of its occurrence; (4) and that quantifications binding sentential variables are neither eliminable, substitutional, nor referential. The book develops and defends (1)-(3). It also defends (4) against the sorts of strictures on quantification of such philosophers as Quine and Davidson.

788What is the Logic of Propositional Identity?Logic and Logical Philosophy 15 (1): 3-15. 2006.Propositional identity is not expressed by a predicate. So its logic is not given by the ordinary first order axioms for identity. What are the logical axioms governing this concept, then? Some axioms in addition to those proposed by Arthur Prior are proposed.

907What’s So Special About Sentences?Communication and Cognition: An Interdisciplinary Quarterly Journal 28 (4): 409-25. 1995.This paper is a discussion of Frege's maxim that it is only in the context of a sentence that a word has a meaning. Quine reads the maxim as saying that the sentence is the fundamental unit of significance. Dummett rejects this as a truism. But it is not a truism since it stands in opposition to a conception of meaning held by John Locke and others. The maxim denies that a word has a sense independently of any sentence in which it occurs. Dummett says this denial is inconsistent with the fact th…Read more

185Does scientific realism entail mathematical realism?Facta Philosophica 5 (1): 173-182. 2003.Hilary Putnam suggests that the essence of the realist conception of mathematics is that the statements of mathematics are objective so that the true ones are objectively true. An argument for mathematical realism, thus conceived, is implicit in Putnam's writing. The first premise is that within currently accepted science there are objective truths. Next is the premise that some of these statements logically imply statements of pure mathematics. The conclusion drawn is that some statements of pu…Read more

101God and empty termsInternational Journal for Philosophy of Religion 18 (3). 1985.This paper is a criticism of Plantinga’s analysis of a version of the ontological argument. He thinks it is obvious that his version is valid and that the only question of interest is whether a key premise is true. The paper lays out two relevant semantical accounts of modal logic. It contends that Plantinga needs to show that one is preferable to the other.
