[Brian P. McLaughlin] In recent years, some philosophers have claimed that we can know a priori that certain external world skeptical hypotheses are false on the basis of a priori knowledge that we are in certain kinds of mental states, and a priori knowledge that those mental states are individuated by contingent environmental factors. Appealing to a distinction between weak and strong a priority, I argue that weakly a priori arguments of this sort would beg the question of whether the (...) skeptical hypothesis under assessment is true, and that the prospect of a sound strongly a priori argument of this sort seems dim. \\\ [David Owens] Contemporary discussion of scepticism focuses on the possibility that most or all of our beliefs might be false. I argue that the hypothesis of massive falsity and the associated 'problem of the external world' are inessential to the scepticisms of Descartes and Hume. What drives Cartesian and Humean scepticism is the demand for certainty: any possibility of error, however local, must be ruled out before we can claim either justified belief or knowledge. Contemporary philosophers have ignored this form of scepticism because they doubt that the demand for certainty can be motivated. But Descartes provides a sound motivation for this demand in the Meditations. (shrink)

Physicalism, the thesis that everything is physical, is one of the most controversial problems in philosophy. Its adherents argue that there is no more important doctrine in philosophy, whilst its opponents claim that its role is greatly exaggerated. In this superb introduction to the problem Daniel Stoljar focuses on three fundamental questions: the interpretation, truth and philosophical significance of physicalism. In answering these questions he covers the following key topics: -/- (i)A brief history of physicalism and its definitions, (ii)what a (...) physical property is and how physicalism meets challenges from empirical sciences, (iii)'Hempel’s dilemma’ and the relationship between physicalism and physics, (iv)physicalism and key debates in metaphysics and philosophy of mind, such as supervenience, identity and conceivability, and (v)physicalism and causality. -/- Additional features include chapter summaries, annotated further reading and a glossary of technical terms, making Physicalism ideal for those coming to the problem for the first time.

_Naming and Necessity_ has had a great and increasing influence. It redirected philosophical attention to neglected questions of natural and metaphysical necessity and to the connections between these and theories of naming, and of identity. This seminal work, to which today's thriving essentialist metaphysics largely owes its impetus, is here reissued in a newly corrected form with a new preface by the author. If there is such a thing as essential reading in metaphysics, or in philosophy of language, this is (...) it. (shrink)

Chalmers’s anti-materialist argument runs as follows.

This appeared in Philosophy and Phenomenological Research 59:473-93, as a response to four papers in a symposium on my book The Conscious Mind . Most of it should be comprehensible without having read the papers in question. This paper is for an audience of philosophers and so is relatively technical. It will probably also help to have read some of the book. The papers I’m responding to are: Chris Hill & Brian McLaughlin, There are fewer things in reality than are (...) dreamt of in Chalmers’ philosophy Brian Loar, David Chalmers’ The Conscious Mind Sydney Shoemaker, On David Chalmers’ The Conscious Mind Stephen Yablo, Concepts and consciousness Contents.

The explanatory gap . Consciousness is a mystery. No one has ever given an account, even a highly speculative, hypothetical, and incomplete account of how a physical thing could have phenomenal states. Suppose that consciousness is identical to a property of the brain, say activity in the pyramidal cells of layer 5 of the cortex involving reverberatory circuits from cortical layer 6 to the thalamus and back to layers 4 and 6,as Crick and Koch have suggested for visual consciousness. .) (...) Still, that identity itself calls out for explanation! Proponents of an explanatory gap disagree about whether the gap is permanent. Some say that we are like the scientifically naive person who is told that matter = energy, but does not have the concepts required to make sense of the idea. If we can acquire these concepts, the gap is closable. Others say the gap is uncloseable because of our cognitive limitations. Still others say that the gap is a consequence of the fundamental nature of consciousness. (shrink)

Cognitive science is shamelessly materialistic. It maintains that human beings are nothing more than complex physical systems, ultimately and completely explicable in mechanistic terms. But this conception of humanity does not ?t well with common sense. To think of the creatures we spend much of our day loving, hating, admiring, resenting, comparing ourselves to, trying to understand, blaming, and thanking -- to think of them as mere mechanisms seems at best counterintuitive and unhelpful. More often it may strike us as (...) ludicrous, or even abhorrent. We are. (shrink)

Ignorance and Imagination advances a novel way to resolve the central philosophical problem about the mind: how it is that consciousness or experience fits into a larger naturalistic picture of the world. The correct response to the problem, Stoljar argues, is not to posit a realm of experience distinct from the physical, nor to deny the reality of phenomenal experience, nor even to rethink our understanding of consciousness and the language we use to talk about it. Instead, we should view (...) the problem itself as a consequence of our ignorance of the relevant physical facts, Stoljar shows that this change of orientation is well motivated historically, empirically, and philosophically, and that it has none of the side effects it is sometimes thought to have. The result is a philosophical perspective on the mind that has a number of far-reaching consequences: for consciousness studies, for our place in nature, and for the way we think about the relationship between philosophy and science.
