Intended for the first course in logic, The Power of Logic (POL) is written with the conviction that logic is the most important course that college students take. POL preserves the balance between informal and formal logic. Layman;s direct and accessible writing style, along with his plentiful examples, imaginative exercises, and POL;s accompanying Logic Tutor make this the best text for logic classes today.day.

This book provides a novel interpretation of the ideas about language in Ludwig Wittgenstein's Philosophical Investigations. Travis places the "private language argument" in the context of wider themes in the Investigations, and thereby develops a picture of what it is for words to bear the meaning they do. He elaborates two versions of a private language argument, and shows the consequences of these for current trends in the philosophical theory of meaning.

This article develops Frege's conception of answerability, and his correlative views on psychologism of the first sort. Compared to prior philosophers, such as British empiricists, Frege is a minimalist in the demands he sets on answerability. If he is ever less than minimalist, that is something that flows out of his particular conception of logic. The article then turns to Wittgenstein's conception of answerability, by which Frege is not quite minimalist enough. That allows us to see how the pursuit of (...) answerability might lead to psychologism of the second kind. (shrink)

A scholarly synthesis of biblical studies and Christian social ethics, designed to provide a biblical argument for intentional institutional change on behalf of social justice.

This scholarly synthesis of biblical studies and Christian social ethics is designed to provide a biblical argument for intentional institutional change on behalf of social justice. Stephen Charles Mott provides a biblical and ethical guide on ways to implement that change. The first part of the book, providing the biblical theology of intentional social change, deals with the central concepts in biblical and theological ethics: grace, evil, love, justice, and the Reign of God. Christian social change must be (...) rooted not only in justice, but in the grace received through the death and resurrection of Christ. The second part evaluates ethical and theological methods for carrying out that intentional social change. It offers a study of evangelism, counter community, civil disobedience, armed revolution, and political reform. It shows the contribution of each as well as the strong limitations of each used in isolation. A recurring theme of the book is the scriptural insistence on the priority of justice as taking upon oneself the cause of the oppressed. Justice is understood on bringing back into the community those who are near to falling out of it. Political authority has a vital role in social change for justice. It is essential that a Christian use all available and legitimate means of meeting basic needs by providing for all what is essential for inclusion in society. In this revised edition, Mott updates the contemporary illustrations and includes his own further reflections in the last thirty years on this topic. (shrink)

Multiple theories of problem-solving hypothesize that there are distinct qualitative phases exhibited during effective problem-solving. However, limited research has attempted to identify when transitions between phases occur. We integrate theory on collaborative problem-solving with dynamical systems theory suggesting that when a system is undergoing a phase transition it should exhibit a peak in entropy and that entropy levels should also relate to team performance. Communications from 40 teams that collaborated on a complex problem were coded for occurrence of problem-solving processes. (...) We applied a sliding window entropy technique to each team's communications and specified criteria for identifying data points that qualify as peaks and determining which peaks were robust. We used multilevel modeling, and provide a qualitative example, to evaluate whether phases exhibit distinct distributions of communication processes. We also tested whether there was a relationship between entropy values at transition points and CPS performance. We found that a proportion of entropy peaks was robust and that the relative occurrence of communication codes varied significantly across phases. Peaks in entropy thus corresponded to qualitative shifts in teams’ CPS communications, providing empirical evidence that teams exhibit phase transitions during CPS. Also, lower average levels of entropy at the phase transition points predicted better CPS performance. We specify future directions to improve understanding of phase transitions during CPS, and collaborative cognition, more broadly. (shrink)

There is a view abroad on which perceptual experience has representational content in this sense: in it something is represented to the perceiver as so. On the view, a perceptual experience has a face value at which it may be taken, or which may be rejected. This paper argues that that view is mistaken: there is nothing in perceptual experience which makes it so that in it anything is represented as so. In that sense, the senses are silent, or, in (...) Austin's term, dumb. Perceptual experience is not as such either veridical or delusive. It may mislead, but it does not take representation to accomplish that. (shrink)

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.

In this paper we suggest that differing approaches to the science of social cognition mirror the arguments between radical embodied and traditional approaches to cognition. We contrast the use in social cognition of theoretical inference and mental simulation mechanisms with approaches emphasizing a direct perception of others’ mental states. We build from a recent integrative framework unifying these divergent perspectives through the use of dual-process theory and supporting social neuroscience research. Our elaboration considers two complementary notions of direct perception: one (...) primarily stemming from ecological psychology and the other from enactive cognition theory. We use this as the foundation from which to offer an account of the informational basis for social information and assert a set of research propositions to further the science of social cognition. In doing so, we point out how perception of the minds of others can be supported in some cases by lawful information, supporting direct perception of social affordances and perhaps, mental states, and in other cases by cues that support indirect perceptual inference. Our goal is to extend accounts of social cognition by integrating advances across disciplines to provide a multi-level and multi-theoretic description that can advance this field and offer a means through which to reconcile radical embodied and traditional approaches to cognitive neuroscience.

Charles Travis presents a series of essays in which he has developed his distinctive view of the relation of thought to language. The key idea is "occasion-sensitivity": what it is for words to express a given concept is for them to be apt for contributing to any of many different conditions of correctness (notably truth conditions). Since words mean what they do by expressing a given concept, it follows that meaning does not determine truth conditions. This view ties (...) thoughts less tightly to the linguistic forms which express them than traditional views of the matter, and in two directions: a given linguistic form, meaning fixed, may express an indefinite variety of thoughts; one thought can be expressed in an indefinite number of syntactically and semantically distinct ways. Travis highlights the importance of this view for linguistic theory, and shows how it gives new form to a variety of traditional philosophical problems. (shrink)

Charles Travis presents a series of essays on philosophy of perception, inspired by the insights of Gottlob Frege. He engages with a range of contemporary thinkers, and explores key issues including how perception can make the world bear on what we do or think, and what sorts of capacities we draw on in representing something as (being) something.

Let us begin with a piece of intellectual history. The story begins in a period encapsulating the second world war – say the ‘40’s, give and take a bit. Around then, it began to be argued with force that an expression – e.g., an English one – while it well might mean something, does not say anything, and notably no one thing in particular. The principal behind the argument was surely J.L. Austin, though, I would claim, the same point was (...) argued in a somewhat different way by Wittgenstein. The intended point was not merely a grammatical one: we say of an expression that it means such and such, but not that it says such and such. Be that as it may, the main point was quite substantive: typically, an English expression is such that, with its meaning fixed, there are a variety of distinct things to be said in using it on some production of it or other.

What were Shakespeare's final thoughts on history, tragedy, and comedy? Shakespeare's Last Plays focuses much needed scholarly attention on Shakespeare's "Late Romances." The work—a collection of newly commissioned essays by leading scholars of classical political philosophy and literature—offers careful textual analysis of Pericles, Prince of Tyre, Cymbeline, The Winter's Tale, The Tempest, All is True, and The Two Noble Kinsmen. The essays reveal how Shakespeare's thought in these final works compliments, challenges, fulfills, or transforms previously held conceptions of the playwright (...) and his political-philosophical views.

What words mean plays a role in determining when they would be true; but not an exhaustive one. For that role leaves room for variation in truth conditions, with meanings fixed, from one speaking of words to another. What role meaning plays depends on what truth is; on what words, by virtue of meaning what they do are requied to have done (as spoken) in order to have said what is true. There is a deflationist position on what truth is: (...) the notion is exhausted by a given, specified, mass of 'platitudes', each to the effect that if words said (say) things to be thus, things must be that way. (The thought that thus-and-so is true iff thus-and-so.) These platitudes, and so deflationism, miss that aspect of truth that determines meaning's role. Truth requires words to have the uses which, given what they mean, they should have in the circumstances of their speaking. Through this link with use, when words would be true is a factor fixing what it is they said. (shrink)

The main thrust of the present work is to show why truth and truth bearers lie essentially beyond the descriptive reach of semantics, and to outline a theory of ...

Thought's Footing is an enquiry into the relationship between the ways things are and the way we think and talk about them. It is also a study of Wittgenstein's Philosophical Investigations: Charles Travis develops his account of certain key themes into a unified view of the work as a whole. The central question is: how does thought get its footing? How can the thought that things are a certain way be connected to things being that way?

A continuous Oxford tradition on knowledge runs from John Cook Wilson to John McDowell. A central idea is that knowledge is not a species of belief, or that, in McDowell's terms, it is not a hybrid state; that, moreover, it is a kind of taking in of what is there that precludes one's being, for all one can see, wrong. Cook Wilson and McDowell differ on what this means as to the scope of knowledge. J.L. Austin set out the requisite (...) foundations for McDowell to be right. McDowell has shown why the tradition, and his version of it, need to be right. But he does not accept Austin's innovation. That is a shame. For, despite McDowell's very great insightfulness, precisely that much separates him from a very powerful, and correct, view of what knowledge is. (shrink)

What makes a veil of perception? Is it merely would-be objects of perceptual awareness, extraneous to the ‘environmental realities’ of which we judge? Or is it merely the presence of something extraneous along the route from perceptual awareness to awareness that our environment is thus and so? In his Mark Sacks lecture John McDowell seems to suppose something like the first answer. This essay argues for the second, thus that he himself imposes such a veil.

What is insensitive semantics (also semantic minimalism, henceforth SM)? That will need to emerge, if at all, from the authors’ (henceforth C&L) objections to what they see as their opponents. They signal two main opponents: moderate contextualists (henceforth MCs); and radical contextualists (henceforth RCs). I am signaled as a main RC. I will thus henceforth represent that position in propria persona. In most general lines the story is this: MC collapses into RC; RC is incoherent, or inconsistent, on various counts; (...) SM is thus the only game in town. As to all of that, we shall see. (shrink)

The role of words in thought expression is to make recognisable what thought is expressed. The role of a definite description in the expression of a singular thought is to make recognisable with respect to what object the thought is singular. That different definite descriptions may play this role for one object settles nothing as to how such thoughts are to be counted. What does settle this? The present brief is: nothing in the notion of a thought as such. For (...) good reason. A way of counting thoughts is under two opposing constraints. First, it must serve the needs of proof. Second, it must yield thoughts which are shareable. Simultaneously satisfying both these demands requires there to be no one way of counting thoughts which is the right one tout court. That is, the notion same thought is an occasion-sensitive notion. (shrink)

Pragmatics concerns the linguistic phenomena left untreated by phonology, syntax, and semantics. This chapter argues that the pragmatic view is the right one; that it is intrinsically part of what expressions of English mean that any English sentence may, on one speaking of it or another, have any of indefinitely many different truth‐conditions, and that any English expression may, meaning what it does, make any of many different contributions to truth‐conditions of wholes in which it figures as a part. The (...) pragmatic view gives a substantially different form to virtually every philosophic problem, not just in philosophy of language, but wherever puzzles arise. Given words may have any of many semantics, compatibly with what they mean. Words in fact vary their semantics from one speaking of them to another. In that case, their semantics on a given speaking cannot be fixed simply by what they mean. (shrink)

This book is about Gottlob Frege. The guiding thought is that Frege left philosophy a legacy which has been largely ignored, not least of all by his admirers. In order of logical priority, Frege's first concern was to locate the law-like behaviour of truths and falsehoods merely by virtue of their being such. The just-mentioned legacy lies in his first step towards that goal. It consists in winnowing the 'logical' from the 'psychological', the business of being true as such from (...) that of holding, or holding forth as true-and to keep these separate. A first lesson: what belongs to what is thus abstracted cannot be read directly back into what it was abstracted from. This is what is most widely ignored. The book is divided in three parts. The first presents Frege's general picture of the business of being true-of what belongs to the abstraction. The second is primarily concerned with steps Frege takes between 1891 and 1895, to pave the way for what became, after logic itself, his central project, that whose attempted carrying out is contained in Grundgesetze I. The third part concerns views of logic, truth, the inexorableness of logic, which Frege eventually came to hold, and what it might be to study 'The Mind' as opposed to minds. (shrink)

This is a response to Marie McGinn, who, roughly, lined me up with J. L. Austin over against GEM Anscombe and Wittgenstein on the issue whether perception is (or can be) intentional. I do not mind being aligned with Austin, but argue that this is the wrong way to line things up. I stand equally with Wittgenstein. Anscombe turns out to be odd man out on this one.
