This article aims to review the standard objections to dualism and to argue that either they will fail to convince someone committed to dualism or are flawed on independent grounds. I begin by presenting the taxonomy of metaphysical positions on concrete particulars as they relate to the dispute between materialists and dualists, and in particular substance dualism is defined. In the first section, several kinds of substance dualism are distinguished and the relevant varieties of this kind of dualism are selected. The remaining sections are analyses of the standard objections to substance dualism: It is uninformative, has troubles accounting for soul individuation, causal pairing and interaction, violates laws of physics, is made implausible by the development of neuroscience and it postulates entities beyond necessity. I conclude that none of these objections is successful.

What do we learn when we focus analysis – not so much on the content of experience – as on its universal features and functioning? Descartes believed that such focus (when exercised by someone employing his first-personal method of inquiry) held the key to the fundamental metaphysics of our universe – that it could reveal fundamental truths about the nature of substance, or at any rate could reveal some fundamental metaphysical categories and their contrasts. He believed such focus could lead to a certain doctrine of dualism. Philosophers now widely hold that Descartes' method was profoundly wrongheaded, in no way a candidate method for illuminating the material universe that is our own. In fact, however, Descartes' method is considerably more serviceable. While unable to do what Descartes thought it could do, nonetheless it is ideal for examining a taxon that this essay will refer to as grammar or structure in the most general sense. Grammar is a contrary of content or materiality, though not the only one since materiality enjoys multiple contraries. Thus Descartes' method can lead us to a certain dualism, but not the one that Descartes imagined.

The object of this essay is to discuss Ludwig Wittgenstein's remarks in Philosophical Investigations and elsewhere in the posthumously published writings concerning the role of therapy in relation to philosophy. Wittgenstein's reflections seem to suggest that there is a kind of philosophy or mode of investigation targeting the philosophical grammar of language uses that gratuitously give rise to philosophical problems, and produce in many thinkers philosophical anxieties for which the proper therapy is intended to offer relief. Two possible objectives of later Wittgensteinian therapy are proposed, for subjective psychological versus objective semantic symptoms of ailments that a therapy might address for the sake of relieving philosophical anxieties. The psychological in its most plausible form is rejected, leaving only the semantic. Semantic therapy in the sense defined and developed is more general and long-lasting, and more in the spirit of Wittgenstein's project on a variety of levels. A semantic approach treats language rather than the thinking, language-using subject as the patient needing therapy, and directs its attention to the treatment of problems in language and the conceptual framework a language game use expresses in its philosophical grammar, rather than to soothing unhappy or socially ill-adjusted individual psychologies.

Politics has been defined in different and contradictory ways in the last century or so. If politics is to be a single subject of study then contradictory theories should be capable of being related together. In this article I argue that they can be related in terms of what I call the Aristotelian criterion. The article is in four parts. Firstly, I discuss the problem of defining politics; secondly, I introduce the criterion; thirdly, I consider five modern theories of politics (those of Arendt, Oakeshott, Collingwood, Schmitt and Rancière) in relation to the criterion; and fourthly, I use the criterion to put forward an original and capacious definition of politics.1

Because of the idealizations involved in the ideas of a total state of the world and of all the laws of nature, the thesis of all-encompassing determinism is unverifiable. Our everyday non-scientific talk of causation does not imply determinism; nor is it needed for the Kantian argument for a general causal framework as a condition for experience of an objective world. Determinism is at best a regulative ideal for science, something to be approached but never reached.
