I am glad that David Chalmers has now come round to the view that explaining the 'problem intuitions' about consciousness is the key to a satisfactory philosophical account of the topic. I find it surprising, however, given his previous writings, that Chalmers does not simply attribute these intuitions to the conceptual gap between physical and phenomenal facts. Still, it is good that he doesn't, given that this was always a highly implausible account of the problem intuitions. Unfortunately, later in his paper Chalmers slides back into his misguided previous emphasis on the conceptual gap, in his objections to orthodox a posteriori physicalism. Because of this he fails to appreciate how this orthodox physicalism offers a natural solution to the challenges posed by consciousness.

Muitas ideias diferentes desfilam sob a bandeira do naturalismo filosófico. Entre elas, uma tese sobre método filosófico. A filosofia investiga a realidade do mesmo modo que a ciência. Seus métodos são semelhantes aos métodos científicos, e o conhecimento que ela produz é semelhante ao conhecimento científico. Este “naturalismo metodológico” deve ser distinguido do “naturalismo ontológico”, entendido como uma visão geral sobre os conteúdos da realidade. O naturalismo ontológico sustenta que a realidade envolve nada mais do que as entidades estudadas nas ciências naturais e não contém um reino sobrenatural ou transcendente. Embora os naturalismos ontológico e metodológico reivindiquem uma espécie de afinidade entre filosofia e ciência, as duas doutrinas são amplamente independentes.

This precis explains that _Philosophical naturalism contains three parts. Part I examines arguments for physicalism and maintains I) that all causally relevant special science properties must be realized by physical ones, and II) that all special science laws must reduce to physical ones, apart from the significant category of special laws that result from selection processes. Part II defends a teleological theory of representation and an identity theory of consciousness. Part III defends reliabilism and applies it to inductive scepticism and also defends a fictionalist account of mathematics

This paper is about the nature of conscious sensory properties. My initial thesis is that these properties should not be equated with representational properties. I argue that any such representationalist view is in danger of implying that conscious sensory properties are constituted by relations to propositions or other abstract objects outside space and time; and I add that, even if this implication can be avoided, the broadness of representational properties in any case renders them unsuitable to constitute conscious properties. In place of the representational account, I then defend an equation of conscious sensory properties with intrinsic non‐relational properties of subjects, and I show how this view deals naturally with all the difficulties facing representationalism. I conclude by defending this non‐relational account of conscious experience against arguments from the ‘transparency’ and the ‘intrinsic intentionality’ of experience.

This paper applies a teleosemantic perspective to the question of whether there is genuine representation outside the familiar realm of belief‐desire psychology. I first explain how teleosemantics accounts for the representational powers of beliefs and desires themselves. I then ask whether biological states which are simpler than beliefs and desires can also have representational powers. My conclusion is that such biologically simple states can be ascribed representational contents, but only in a system‐relative way: such states must be ascribed varying contents when viewed as components in different biological systems. I conclude by arguing that ‘the genetic code’ does not even embody this kind of system‐relative representation.

On the first page of The Problem of Consciousness , Colin McGinn asks "How is it possible for conscious states to depend on brain states? How can technicolour phenomenology arise from soggy grey matter?" Many philosophers feel that questions like these pose an unanswerable challenge to physicalism. They argue that there is no way of bridging the "explanatory gap" between the material brain and the lived world of conscious experience , and that physicalism about the mind can therefore provide no answer to the "hard problem" of why brains give rise to consciousness

I am lucky to have two such penetrating commentators as Robert Kirk and Andrew Melnyk. It is also fortunate that they come at me from different directions, and so cover different aspects of my book. Robert Kirk has doubts about the overall structure of my enterprise, and in particular about my central commitment to a distinctive species of phenomenal concepts. Andrew Melnyk, by contrast, offers no objections to my general brand of materialism. Instead he focuses specifically on my discussion of the anti-materialist 'intuition of distinctness', raising questions about my attempt to explain this intuition away, and offering alternative suggestions of his own

My target in this paper is "theories of consciousness". There are many theories of consciousness around, and my view is that they are all misconceived. Consciousness is not a normal scientific subject, and needs handling with special care. It is foolhardy to jump straight in and start building a theory, as if consciousness were just like electricity or chemical valency. We will do much better to reflect explicitly on our methodology first. When we do this, we will see that theories of consciousness are trying to answer a question that isn't there
