In the sixth chapter of The View from Nowhere, Thomas Nagel aims to identify a form of idealism, to isolate the argument for it and to counter this argument. The position that Nagel takes to be idealist is that what there is must be possibly conceivable by us. In this paper, I show that Nagel has not made a convincing case against this position. I then present an alternative case. In light of this alternative case, we have reason to reject an important example that Nagel offers of a contemporary idealist, namely Donald Davidson.

Donald Davidson has argued that 'most of our beliefs must be true' and that global scepticism is therefore false. Davidson's arguments to this conclusion often seem to depend on externalist considerations. Davidson's position has been criticised, however, on the grounds that he does not defeat the sceptic, but rather already assumes the falsity of scepticism through his appeal to externalism. Indeed, it has been claimed that far from defeating the sceptic Davidson introduces an even more extreme version of scepticism according to which we cannot even know the contents of our own minds. This paper argues that these criticisms are mistaken and that Davidson does indeed have grounds to argue that scepticism is false. The externalism that figures in Davidson's antisceptical arguments is shown to be merely an element in Davidson's overall holism according to which the very possibility of having beliefs that could be true or false depends on most of those beliefs being true and their contents known.

Relativism has usually been presented as linked to the limits of translation and understanding. The Principle of Charity was developed to decide the reference of words or the best translation of a sentence. However, the principle has been defined in, at least, two different ways: a naturalistic one, as a pragmatic maxim that guides the interpreter generally; or a transcendental one, as an a priori, necessary condition for someone to be understood. In this paper I will focus on the latter approach, taking Donald Davidson's arguments and his transcendental interpretation of the Principle of Charity as a representative case. Although different versions of the principle can be found in Davidson's writings, and some of them would seem flexible enough to give an account of how interpreter and speaker have different beliefs, all of these versions put understanding and intelligibility at risk. The reason is that the Principle of Charity has a wide scope: to conceive a person as rational, as having beliefs and desires, or as saying something, we have to interpret his/her utterances as revealing a set of beliefs consistent and true, and that maxim is applied to the whole system of sentences. So charity is necessary, we cannot choose it and if we spell out the Principle of Charity in sociological or psychological terms, that is, in empirical terms, we are changing the subject. The transcendental character of the principle has received criticism from various authors who understand it in a naturalistic way. I will conclude that an empirical description of how we use the Principle of Charity when we interpret a speaker's utterance would show the psychological and sociological relevance of relativism.

This paper is concerned with Davidson's argument that very general properties of the theory of interpretation make the skeptical claim that most of our beliefs could turn out to be false insupportable. Conceived as a 'straight' answer to the skeptic Davidson's argument is not especially convincing. In particular, Davidson's answer to the skeptic presupposes a framework that allows for a new and seemingly more radical skepticism according to which we might not even have beliefs at all. Nevertheless, there is a sense in which Davidson's account of content remaps the conceptual terrain in a fashion that absolves us of the need to rule out the scenarios the skeptic describes. The paper will both present the problems Davidson's position has as a 'straight' solution to skepticism, and discuss the way in which his externalism does weaken the strength of the skeptical challenge.

In this paper I present two new arguments against the possibility of an omniscient being. My new arguments invoke considerations of cardinality and resemble several arguments originally presented by Patrick Grim. Like Grim, I give reasons to believe that there must be more objects in the universe than there are beliefs. However, my arguments will rely on certain mereological claims, namely that Classical Extensional Mereology is necessarily true of the part-whole relation. My first argument is an instance of a problem first noted by Gideon Rosen and requires an additional assumption about the mereological structure of certain beliefs. That assumption is that an omniscient being’s beliefs are mereological simples. However, this assumption is dropped when I present my second argument. Thus, I hope to show that if Classical Extensional Mereology is true of the part-whole relation, there cannot be an omniscient being.

l examine the “omniscient interpreter” (OI) argument against scepticism that Donald Davidson published in 1977 only to retract it twenty-two years later. I argue that the argument’s persuasiveness has been underestimated. I defend it against the charges that Davidson assumes the actual existence of an OI and that Davidson’s other philosophical commitments are incompatible with the very conceivability of an OI. The argument’s surface implausibility derivesfrom Davidson’s suggestion that an OI would attribute beliefs using the same methods as afallible human interpreter. But this problem can be remedied via the adoption of an ambiguity theory of belief.J’examine l’argument de “l’interprète omniscient” (IO) contre les objections sceptiques formulées par Donald Davidson en 1977, qu’il a rétractées vingt-deux ans plus tard. Je soutiens que la force de cet argument a été sous-estimée. Je m’inscris en faux contre les critiques voulant que Davidson ait supposé l’existence effective de l’IO, et que les autres croyances philosophiques de Davidson soientincompatibles avec la possibilité de concevoir l’idée d’un IO. Si l’argument semble peu plausible à prime abord, c’est que Davidson a suggéré qu’un IO attribuait les croyances en utilisant les mêmes méthodes qu’un interprète humain faillible. On peut remédier à ce problème en adoptant une théorie de l’ambiguïté des croyances.
