Second, there is a form of ampliative inference that has come to be called ‘inference to the best explanation,’ or more briefly ‘explanatory inference.’ Roughly: From the fact that a certain hypothesis would explain the data at hand better than any other available hypothesis, we infer with some degree of confidence that that leading hypothesis is correct. There is no question but that this inference is often performed. Arguably, every human being performs it many times in a day, perhaps without (...) letup. (shrink)

Philosophers and logicians have long debated how best to understand conditional or hypothetical sentences. William G. Lycan has a distinctive approach to this debate, attending not just to the semantics of such sentences, but equally to their syntax. He shows how insights from linguistic theory help to illuminate problems about the meaning and function of conditionals. For instance, philosophers and logicians have had problems analysing the locutions 'only if', 'unless', and 'even if'. Lycan sets out a general semantic (...) theory of conditionals which works for all such sentences; he assigns meanings to them in a way that explains how and why those meanings depend upon features of utterance context. According to Lycan's theory the 'if'-clauses refer to items called 'events', 'circumstances', or 'conditions'.Real Conditionals gives at last the definitive presentation of this original approach to a topic at the intersection of philosophy, logic, and linguistics. Lycan's characteristically lively and witty expository style ensures that it can be enjoyed by readers from all three disciplines. (shrink)

This is the first detailed study to explore the little-understood notions of "knowing who someone is," "knowing a person's identity," and related locutions. It locates these notions within the context of a general theory of believing and a semantical theory of belief- and knowledge-ascriptions.The books's main contention is that what one knows, when one knows who someone is, is not normally an identity in the numerical sense of "a = b," but rather a certain sort of predication to know who (...) someone is is just to know that that person is F, where "F" is a predicate that is "important," in a technical sense defined by the authors, for the purposes determined by context. Their book offers a rigorous formal semantics for ascriptions of knowing and of knowing-who in particular, solving such well-known problems and paradoxes as Kripke's Puzzle, and Quines difficulties with de re belief, along the way.The authors apply their analysis to each of several important issues in philosophy of language, philosophy of mind, and ethical theory in which the previously unexamined notion of "knowing who" has loomed large-the mechanics of linguistic referring, the foundations of epistemic logic, problems of self-knowledge and self-regarding belief, universalizability and "Golden Rule" arguments in ethics, and moral "personalism" versus "impartialism."Stephen Boër is Professor of Philosophy at the Ohio State University.

This paper endorses and defends M. J. Cresswell's view that the distinction drawn in linguistic semantics between strictly "logical" implication and merely lexical implication is bogus, and then explores the bad consequences that concession has for the Davidsonian semantic program. A pattern of semantic explanation made famous by Davidson's "The logical form of action sentences" is shown to be far less interesting than has been thought.

Higher-Order Perception (HOP) theories in the philosophy of mind are offered as explanations of what it is that makes a mental state a conscious state. According to HOP, a mental state is conscious just in case it is itself represented in a quasi-perceptual way by an internal monitor or scanning device. We start with one of the more popular objections to HOP and a seemingly innocuous concession to it: identifying the internal monitor with the faculty of attention. We show how (...) this concession undermines HOP. (shrink)

An argument is developed at some length to show that any semantical theory which treats superficially nonperformative sentences as being governed by performative prefaces at some level of underlying structure must either leave those sentences semantically uninterpreted or assign them the wrong truth-conditions. Several possible escapes from this dilemma are examined; it is tentatively concluded that such hypotheses as the Ross-Lakoff-Sadock Performative Analysis should be rejected despite their attractions.

In this book William G. Lycan offers an epistemology of philosophy itself, a partial method for philosophical inquiry. The epistemology features three ultimate sources of justified philosophical belief. First, common sense, in a carefully restricted sense of the term-the sorts of contingentpropositions Moore defended against idealists and skeptics. Second, the deliverances of well confirmed science. Third and more fundamentally, intuitions about cases in a carefully specified sense of that term. The first half of On Evidence in Philosophy expounds a (...) version of Moore's method and applies it to each of several issues. This version is shown to resist all the standard objections to Moore; most of them do not even apply. It is argued, in Chapters 5 and 6, that philosophical method is far lesspowerful than most have taken it to be. In particular, deductive argument can accomplish very little, and hardly ever is an opposing position refuted except by common sense or by science. The final two chapters defend the evidential status of intuitions and the Goodmanian method of reflectiveequilibrium; it is argued that philosophy always and everywhere depends on them. The method is then set within a more general explanatory-coherentist epistemology, which is shown to resist standard forms of skepticism.In sum, William G. Lycan advocates a picture of philosophy as a very wide explanatory reflective equilibrium incorporating common sense, science, and our firmest intuitions on any topic-and nothing more, not ever.

This book contends that insufficient attention has been paid to the syntax of conditionals, as investigated by linguists.

_Philosophy of Language_ introduces the student to the main issues and theories in twentieth-century philosophy of language. Topics are structured in three parts in the book. Part I, Reference and Referring Expressions, includes topics such as Russell's Theory of Desciptions, Donnellan's distinction, problems of anaphora, the description theory of proper names, Searle's cluster theory, and the causal-historical theory. Part II, Theories of Meaning, surveys the competing theories of linguistic meaning and compares their various advantages and liabilities. Part III, Pragmatics and (...) Speech Acts, introduces the basic concepts of linguistic pragmatics, includes a detailed discussion of the problem of indirect force and surveys approaches to metaphor. Unique features of the text: * chapter overviews and summaries * clear supportive examples * study questions * annotated further reading * glossary. (shrink)

Frege begins his exposition of the symbol system employed in his Begriffsschrift by introducing the sign ⟝, whereby, he says, “[a] judgment is always to be expressed”.[The judgment sign] stands to the left of the sign or complex of signs in which the content of the judgment is given. If we omit the little stroke at the left of the horizontal stroke, then the judgment is to be transformed into a mere complex of ideas; the author is not expressing his (...) recognition or nonrecognition of the truth of this.

Despite the current resurgence of modest forms of mind–body dualism, traditional Cartesian immaterial-substance dualism has few, if any, defenders. This paper argues that no convincing case has been made against substance dualism, and that standard objections to it can be credibly answered.
