Statistical mechanics is one of the crucial fundamental theories of physics, and in his new book Lawrence Sklar, one of the pre-eminent philosophers of physics, offers a comprehensive, non-technical introduction to that theory and to attempts to understand its foundational elements. Among the topics treated in detail are: probability and statistical explanation, the basic issues in both equilibrium and non-equilibrium statistical mechanics, the role of cosmology, the reduction of thermodynamics to statistical mechanics, and the alleged foundation of the very notion (...) of time asymmetry in the entropic asymmetry of systems in time. The book emphasises the interaction of scientific and philosophical modes of reasoning, and in this way will interest all philosophers of science as well as those in physics and chemistry concerned with philosophical questions. The book could also be read by an informed general reader interested in the foundations of modern science. (shrink)

This paper challenges David Chalmers' proposed division of the problems of consciousness into the `easy' ones and the `hard' one, the former allegedly being susceptible to explanation in terms of computational or neural mechanisms and the latter supposedly turning on the fact that experiential `qualia' resist any sort of functional definition. Such a division, it is argued, rests upon a misrepresention of the nature of human cognition and experience and their intimate interrelationship, thereby neglecting a vitally important insight of Kant. (...) From a Kantian perspective, our capacity for conceptual thought is so inextricably bound up with our capacity for phenomenal consciousness that it is an illusion to imagine that there are any `easy' problems of consciousness, resolvable within the computational or neural paradigms.

Causation and the laws of nature are nothing over and above the pattern of events, just like a movie is nothing over and above the sequence of frames. Or so I will argue. The position I will argue for is broadly inspired by Hume and Lewis, and may be expressed in the slogan: what must be, must be grounded in what is.

This paper is a response to the 26 commentaries on my paper "Facing Up to the Problem of Consciousness". First, I respond to deflationary critiques, including those that argue that there is no "hard" problem of consciousness or that it can be accommodated within a materialist framework. Second, I respond to nonreductive critiques, including those that argue that the problems of consciousness are harder than I have suggested, or that my framework for addressing them is flawed. Third, I address positive (...) proposals for addressing the problem of consciousness, including those based in neuroscience and cognitive science, phenomenology, physics, and fundamental psychophysical theories.

In this thesis I provide a survey over different approaches to second-order logic and its interpretation, and introduce a novel approach. Of special interest are the questions whether second-order logic can count as logic in some proper sense of logic, and what epistemic status it occupies. More specifically, second-order logic is sometimes taken to be mathematical, a mere notational variant of some fragment of set theory. If this is the case, it might be argued that it does not have the (...) "epistemic innocence" which would be needed for, e.g., foundational programmes in mathematics for which second-order logic is sometimes used. I suggest a Deductivist conception of logic, that characterises logical consequence by means of inference rules, and argue that on this conception second-order logic should count as logic in the proper sense.

This paper analyses the features of Kant’s transcendental philosophy, which Kant himself described as transcendental idealism. On the one hand, Kant’s transcendentalism rests on the distinction between things in themselves and appearances. On the other hand, our ‘mode of cognition’ [Critique, B25] cognition is representative in that is based on representations — subjective and objective ones. A synthesis of the above considerations suggests that Kant’s transcendentalism rests on the conceptual triad “[objective] object — appearance — and [mental] representation “. Kant’s (...) transcendentalism is impossible without the ‘premise’ of appearance. The correct interpretation of Kant’s transcendental philosophy should keep the double difference of appearance both from thing–in–itself and representation. In this transcendental triad, the Kantian appearance has an intermediate status since it is located between objective things and subjective representations. However, the conceptual status of the appearance needs to be clarified, since Kant himself does not give a clear answer to this question, and at present there are several interpretations, differing primarily in the definition of the concept of the appearance. For me, appearance can be correlated with objective–objectual representation. It would be unwise to identify appearance with thing in itself, which was characteristic of pre–Kantian philosophy, or appearance with representation, which was the case in phenomenalist interpretations of transcendental idealism à la Berkley. The Kantian appearance, as emphasised in BXXVII of his Critique, is an appearance of an object, which — although implicitly — suggests a semantic relationship of reference. In this case, the appearance is not an object, but just ‘a designation of an object’ [Critique, B235]. Appearance is impossible without what appears in it. This paper puts forward a number of arguments in favour of the objectual status of Kant’s concept of appearance. (shrink)

The functionalist view of the nature of the mind is now widely accepted. Like behaviorism and physicalism, functionalism seeks to answer the question "What are mental states?" I shall be concerned with identity thesis formulations of functionalism. They say, for example, that pain is a functional state, just as identity thesis formulations of physicalism say that pain is a physical state.

A common conception of what it is for one property to “realize” another suggests that it is the realizer property that does the causal work, and that the realized property is epiphenomenal. The same conception underlies George Bealer’s argument that functionalism leads to the absurd conclusion that what we take to be self-ascriptions of a mental state are really self-ascriptions of “first-order” properties that realize that state. This paper argues for a different concept of realization. A property realizes another if (...) its “forward looking” causal features are a subset of those of the property realized. The instantiation of the realizer property will include the instantiation of the property realized; and when the effects produced are due to the causal features of the latter, it is the instantiation of it that is appropriately regarded as their cause. Epiphenomenalism is avoided, and so is Bealer’s absurd conclusion. (shrink)
