A reductive theory of collective intentionality would imply that the ‘official’ intentions of an oppressive political authority cannot be constructed from the intentions of individuals when they follow the authority's rules. This makes it difficult to explain the unraveling of official group plans through time in a seemingly consistent fashion, and the corresponding source of coercion. A non-reductive theory, on the other hand, cannot capture whether the actions of individuals in an oppressive society are free or coerced, so long as a manifest institutional structure and rules are in place. I put forward a hybrid account of group intentionality that is capable of articulating why oppressive political power is illegitimate, which comes down to the official and individual intentions in joint group actions diverging in such a way that individuals are not governed on the basis of dependent reasons.

John Campbell proposed a so-called simple view of colours according to which colours are categorical properties of the surfaces of objects just as they normally appear to be. I raised an invertion problem for Campbell's view according to which the senses of colour terms fail to match their references, thus rendering those terms meaningless—or so I claimed. Gabriele de Anna defended Campbell's view against my example by contesting two points in particular. Firstly, de Anna claimed that there is no special problem here for the simple view of colours, a similar invertion story could apply to primary qualities terms for shapes. Secondly, de Anna purported to give an account of the senses and references of colour terms in my invertion story which renders the senses and references of those terms mutually consistent.

In this paper I contested both of de Anna's claims. Regarding the first, I argue that his imagined invertion of apparent shapes is not epistemically stable, in contrast to the invertion of apparent shapes is not epistemically stable, in contrast to the invertion of apparent colours. Hence the victims of apparently inverted shapes would be able to discover the mismatch of senses and refences of their shape terms, in contrast to the victims of apparent invertions of colours. Regarding the second, I argue that de Anna's account of the victim's colour terms itself uses and not merely mentions so-called colours terms. Hence de Anna' account of them is itself meaningless due to a mismatch of sense and reference. So I conclude that my objection to Campbell's simple view of colours stands.

Architectural theory arises from building, when the mind considers its symbolic relations to its own constructions. The intent of this essay is to discuss the intellectual causes that precede building and precede theory. It considers certain fundamental dualities in our thinking about architecture—such as image and word; type and model; imitation and invention—and the role they play in its making, its perfection as an art, and the eventual elaboration of its tenets into a theory. At a time when theories of architecture proliferate as expressions of ‘personal philosophies,’ a careful and incisive philosophical approach to if, how, and when does theory become formative of building, may ensure that architecture remain faithful to its intrinsic purposes.

The appeal of the moral principle according to which we should treat like cases alike is so great that it verges on the axiomatic, or on the platitudinous. Recently, however, the principle has been challenged in deeply interesting ways. These ways are interesting because they do not invite skepticism about morality at large, but about the specific claim that what is good (or bad) for an agent in a given situation must be good (or bad) for any other similarly situated agent. I here assess the post-challenge viability of the principle. In a sense, the principle survives, but this is neither an unqualified victory nor an inspiring result. The examination of these matters contains an important (and under-investigated) lesson about the nature of moral experience.

The claim that happiness and virtue ought to be proportionate to one another has often been expressed in the idea of a future world of divine justice, despite many moral difficulties with this idea. This paper argues that human efforts to enact such a proportionment are, ironically, justified by the same reasons that make the idea of divine justice seem so problematic. Moralists have often regarded our frailty and fallibility as reasons for abstaining from the judgment of others; and doubts about our deserving some proportionment of happiness or unhappiness often arise insofar as virtue and vice may be explained on a causal basis. This paper argues that our fallibility and our susceptibility to social influence render judgment and response indispensable, because – given these characteristics – our actions and responses decide the morality that we actually share with one another. In this situation, to ‘judge not’ is to abandon the field to those with no such scruples.

Polemics are a sort of critique typically suffused with inimical emotions and passions. But how are these emotions and passions to be construed? Neither authorial expression nor actual arousal properly account for their role in polemics. Rather, the polemicist must stage an unequal battle between a polemical self and the polemical target vis-à-vis an anticipated audience, skilfully handling, through his or her words, the emotions ascribed to each of them.

This paper presents a functional genealogy of essentialist authenticity. The essentialist account maintains that authenticity is the result of discovering and realizing one's ‘true self’. The genealogy shows that essentialist authenticity can serve the function of supporting continuity in one's individual characteristics. A genealogy of essentialist authenticity is not only methodologically interesting as the first functional genealogy of a contingent concept. It can also deepen the functional understanding of authenticity used in neuroethics, provide a possible explanation for the prevalence of the idea of an essentialist true self and justify the use of the ideal of authenticity. First, essentialist authenticity is defined and explained through the work of Jean-Jacques Rousseau. Second, a general need to have steady characteristics is derived from basic human practices. Third, circumstances that make it more challenging to steady oneself are identified and shown to have become more prevalent in the age of modernity when the ideal of authenticity emerged. Finally, it is shown how essentialist authenticity helps to steady the self.

Wittgenstein wrote ‘While thinking philosophically we see problems in places where there are none. It is for philosophy to show that there are no problems’. He meant that the ‘problems’ philosophers grapple with are of their own making. In a related remark he said: ‘This is the essence of a philosophical problem. The question itself is the result of a muddle. And when the question is removed, this is not by answering it’. Even more explicitly he said: ‘All that philosophy can do is to destroy idols’. As he understood his job, it was not to produce or construct something; his job was entirely destructive. (He compared it to destroying houses of cards.) This is how Wittgenstein thought of philosophy when he thought about it in the abstract, and I share this view of philosophy. I believe that when we see how to dispose of all philosophical categories, our job is finished. For example, in epistemology our job is not to argue that it is possible to know such-and-such because so-and-so; rather, we undermine all those ideas that make it seem as though we could not know such-and-such. Undermining philosophical ideas takes the form: When we philosophise, we are tempted to think so-and-so, but if we consider that idea, and do so while remaining free of all philosophical jargon, we find that we cannot make sense of it.

This paper aims first, to introduce and elaborate upon a certain principle about being (existence), roughly, that once something exists or has being, it cannot lose it: what is cannot, in this sense, unbe; and second, to apply this principle to a well-known issue in the philosophy of time, viz., that of whether future events, like past events, though of course not now occurring, nonetheless have being.

A set of eight mini-discourses. 1. The conceivability of the physical world's running in the opposite temporal direction. 2. Augustine's reason for thinking this is not conceivable for the world of the mind. 3. Trying to imagine being a creature that lives atemporally. 4. Memory's need for causal input. 5. Acting in the knowledge that how one acts is strictly determined. 6. The Newcomb problem. 7. The idea that all voluntary action is intended to be remedial. 8. Haunted by the strangeness of the idea of the past qua past.

I am concerned to examine a mode of argumentation in recent analytic philosophy which, I claim, has its origin in Hegel's ‘dialectical’ method. I give examples of this mode of argumentation in McDowell and Wiggins, followed by a formal representation which distinguishes two possible models both of which have negative and positive aspects. I consider what the commitments of the negative aspect of this approach are, and argue that the desire to avoid naturalism constitutes a common goal. I turn then to its positive aspect, making explicit and criticising some of the metaphilosophical implications contained therein. Finally, I make brief contact with Hegel.

In my book The Comprehensibility of the Universe (OUP, 1998), I argue for a new conception of science that construes science as adopting a hierarchy of increasingly contentless cosmological assumptions about the comprehensibility and knowability of the universe. This view, I argue, solves outstanding problems about science, such as problems of induction, simplicity and verisimilitude. In his essay review of my book (Philosophy75, 2000, 296–309) Friedel Weinert criticizes me for defending a number of views about science. But, as I make clear from quotations from the book, I do not defend the views that Weinert attributes to me.

Deconstruction is commonly associated with the philosophy of Derrida. But there are also non-philosophers who say they engage in deconstruction, for example architects, anthropologists and literary critics. This may lead some people to suppose that deconstruction is not concerned with specifically philosophical problems.
