- Murali Ramachandran, Four Anti-Luminosity Strategies.Timothy Williamson (2000) reckons that hardly any mental state is luminous, i.e. is such that if one were in it, then one would invariably be in a position to know that one was. To this end he presents an argument against the luminosity of feeling cold— which he claims generalizes to other phenomenal states, such as e.g. being in pain. As we shall see, however, no fewer than four lines of argument for that conclusion can be extracted from Williamson’s remarks. This is not to suggest that it is unclear which of these strategies is the one Williamson intends to present; but it is instructive to consider the others for the light they shed on the issue and on his own reasoning. Three of these strategies, including Williamson’s intended, fail with little hope of revival—so I shall argue. The fourth, which has escaped attention in the literature, is perhaps more promising, but I think it too can be resisted, and I sketch a possible line of attack. My aim here is not to defend the luminosity of phenomenal states per se— indeed, I am undecided about the matter—but, rather, to uncover the different strategies which emerge from Williamson’s discussion, and show that they fall short of refuting luminosity.

Timothy Williamson has recently argued that few mental states are luminous , meaning that to be in that state is to be in a position to know that you are in the state. His argument rests on the plausible principle that beliefs only count as knowledge if they are safely true. That is, any belief that could easily have been false is not a piece of knowledge. I argue that the form of the safety rule Williamson uses is inappropriate, and the correct safety rule might not conflict with luminosity.

One of the main strands of the Cartesian tradition is the view that the mental realm is cognitively accessible to us in a special way: whenever one is in a mental state of a certain sort, one can know it just by considering the matter. In that sense, the mental realm is thought to be a cognitive home for us, and the mental states it comprises are luminous. Recently, however, Timothy Williamson has argued that we are cognitively homeless: no mental state is in fact luminous. But his argument depends on an excessively strong account of luminosity. I formulate a weaker conception of luminosity that is unaffected by Williamson’s argument and yet is substantial enough to satisfy those who wish to retain this part of the Cartesian tradition.

Escaping unnoticed, though, is a strikingly similar argument from David Hume. This paper highlights some of the arresting parallels between Williamson’s reasoning and Hume’s that will allow us to appreciate more deeply the plausibility of Williamson’s reasoning and to understand how, following Hume, we can extend this reasoning to undermine the “luminosity” of simple necessary truths. More broadly the parallels help us to identify a common skeptical predicament underlying both arguments, which we shall call “the quarantine problem”. The quarantine problem expresses a deep skepticism about achieving any exalted epistemic state. Further, the perspective gained by the quarantine problem allows us to easily categorize existing responses to Williamson’s anti luminosity argument and to observe the deficiencies of those responses. In sum, the quarantine problem reveals the deeply fallibilistic nature of whatever knowledge we may possess.

He thinks this argument can be generalized to show that no mental states are such that when we are in them we are in a position to know that we are in them. I argue that his argument is a sorites argument in disguise because it relies on the implicit premise that warming up is gradual. Williamson claims that his argument is not a sorites argument; I explain why he has not given us any reason to accept the claim.

The linchpin of Williamson (2000)'s radically externalist epistemological program is an argument for the claim that no non-trivial condition is luminous—that no non-trivial condition is such that whenever it obtains, one is in a position to know that it obtains. I argue that Williamson's anti-luminosity argument succeeds only if one assumes that, even in the limit of ideal reflection, the obtaining of the condition in question and one's beliefs about that condition can be radically disjoint from one another. However, no self-respecting defender of the luminosity of the mental would ever make such an assumption. Thus Williamson can only secure his controversial claims in epistemology by taking for granted certain equally controversial claims in the philosophy of mind. What emerges is that the best bet for defending an internalist epistemology against Williamson's attack is to take there to be a tight, intimate connection between (to take one example) our experiences and our beliefs upon reflection about the obtaining of those experiences, or between (to take another example) the rationality of our beliefs and our beliefs upon reflection about the rationality of those beliefs.

Timothy Williamson (2000 ch. 5) presents a reductio against the luminosity of knowing, against, that is, the so-called KK-principle: if one knows p, then one knows (or is at least in a position to know) that one knows p.1 I do not endorse the principle, but I do not think Williamson’s argument succeeds in refuting it. My aim here is to show that the KK-principle is not the most obvious culprit behind the contradiction Williamson derives.

In Knowledge and Its Limits Timothy Williamson argues against the luminosity of phenomenal states in general by way of arguing against the luminosity of feeling cold, that is, against the view that if one feels cold, one is at least in a position to know that one does. In this paper I consider four strategies that emerge from his discussion, and argue that none succeed.

Timothy Williamson (2000) reckons that hardly any mental state is luminous, i.e. is such that if one were in it, then one would invariably be in a position to know that one was. This paper examines an argument he presents against the luminosity of feeling cold, which he claims generalizes to other phenomenal states, such as e.g. being in pain. As we shall see, the argument fails. However, our deliberations do yield two anti-luminosity results: a simple refutation of the claim that one invariably knows whether one feels cold or not,1 and a counterexample to the luminosity of knowing—in effect, a counterexample to the (KK)- principle.
