Both a priori physicalism and a posteriori physicalism combine a metaphysical and an epistemological thesis. They agree about the metaphysical thesis: our world is wholly physical. Most agree that this requires everything that there is must be necessitated by the sort of truths described by physics. If we call the conjunction of the basic truths of physics P, all physicalists agree that P entails for any truth Q. Where they disagree is whether or not this entailment can be known a priori. The a priori physicalist says it can, the a posteriori physicalist says it cannot. Though a posteriori physicalism is probably the dominant view, it is really a surprising and somewhat unlikely stance. In this article, the nature of the view is discussed, and two arguments are presented that should cause us to look again at the potential of a priori physicalism

It is an intuitively attractive view that the importance of a proposition affects the amount of evidence a subject needs in order to know that proposition—the more important the proposition is to the subject, the more evidence the subject must have in order for her to count as knowing the proposition. This paper argues that because unimportant propositions entail the falsity of very important propositions this position either results in the lack of closure of knowledge under known implication, or it results in standards for evidence being universally high.

'Where am I?' This is something we might expect to hear from hapless explorers or academics with no sense of direction. If we can, we'll explain to our inquirer that he is east of East St. Louis and hope he can find his way from there. If he persists, insisting that he is not really lost, but only cannot find himself no matter how hard he looks, we might reasonably suspect that we are dealing with that peculiarly incorrigible academic explorer, the philosopher. When we hesitantly point to his body, we hear him explain, exasperated, 'No, don't you get it? That's my body, but I'm looking for my self! And I cannot find it!' At this point it is tempting to slip away, convinced that our philosophical friend is ..

It’s a familiar fact that there is something it is like to see red, eat chocolate or feel pain. More recently philosophers have insisted that in addition to this objectual phenomenology there is something it is like for me to eat chocolate, and this for-me-ness is no less there than the chocolatishness. Recognizing this subjective feature of consciousness helps shape certain theories of consciousness, introspection and the self. Though it does this heavy philosophical work, and it is supposed to be relatively obvious to anyone who introspects, it is rather difficult to see just what this phenomenal me-ness is supposed to be; indeed, many philosophers deny it exists. In this paper we try to provide a clear sense of what phenomenal me-ness involves, and then then consider some arguments for the existence of phenomenal me-ness experience as well as some accounts of what gives rise to it. In the end, we argue that the plausible senses of me-ness are a good deal thinner than what often seems to be claimed.

A purely metaphysical formulation of physicalism is surprisingly elusive. One popular slogan is, 'There is nothing over and above the physical'. Problems with this arise on two fronts. First, it is difficult to explain what makes a property 'physical' without appealing to the methodology of physics or to particular ways in which properties are known. This obviously introduces epistemic features into the core of a metaphysical issue. Second, it is difficult to cash out 'over-and-aboveness' in a way that is rigorous, metaphysically pure and extensionally apt for the purposes of the debate. In this paper I will touch on the first problem, but I wish to focus on the second. In particular, I will focus on the claim that supervenience theses cannot define physicalism because they allow classical emergentist dualism through the physicalist door [Horgan 1993; Kim 1998; Wilson 2005]. I will argue that when the relevant supervenience thesis is metaphysical, emergentism is excluded. Against recent arguments to the contrary, I maintain that this is the case even given necessitarianism about natural laws [Wilson 2005]. I will argue that a necessitarian with emergentist sympathies will be forced either into a type of quasi-panpsychism, where our basic physical properties contain the illicit seeds of mentality at their core, or she will be forced to admit that emergence laws are not necessary after all. Either way, the combination of necessitarianism and emergentism does not provide a counterexample to supervenience physicalism.
