Officially, for Kant, judgments are analytic iff the predicate is “contained in” the subject. I defend the containment definition against the common charge of obscurity, and argue that arithmetic cannot be analytic, in the resulting sense. My account deploys two traditional logical notions: logical division and concept hierarchies. Division separates a genus concept into exclusive, exhaustive species. Repeated divisions generate a hierarchy, in which lower species are derived from their genus, by adding differentia(e). Hierarchies afford a straightforward sense of containment: genera are contained in the species formed from them. Kant’s thesis then amounts to the claim that no concept hierarchy conforming to division rules can express truths like ‘7+5= 12.’ Kant is correct. Operation concepts (<7+5>) bear two relations to number concepts: <7> and <5> are inputs, <12> is output. To capture both relations, hierarchies must posit overlaps between concepts that violate the exclusion rule. Thus, such truths are synthetic.

This paper argues for the thesis that, roughly put, it is impossible to talk about absolutely everything. To put the thesis more precisely, there is a particular sense in which, as a matter of semantics, quantifiers always range over domains that are in principle extensible, and so cannot count as really being ‘absolutely everything’. The paper presents an argument for this thesis, and considers some important objections to the argument and to the formulation of the thesis. The paper also offers an assessment of just how implausible the thesis really is. It argues that the intuitions against the thesis come down to a few special cases, which can be given special treatment. Finally, the paper considers some metaphysical ideas that might surround the thesis. Particularly, it might be maintained that an important variety of realism is incompatible with the thesis. The paper argues that this is not the case.

This paper sets out to re-examine the famous Wax Tablet model in Plato’s Theaetetus, in particular the section of it which appeals to the quality of individual souls’ wax as an explanation of why some are more liable to make mistakes than others (194c-195a). This section has often been regarded as an ornamental flourish or a humorous appendage to the model’s main explanatory business. Yet in their own appropriations both Aristotle and Locke treat the notion of variable wax quality as an important part of the model’s utility in dealing with mistake. What, then, is its status for Plato? I shall argue that the section on variable wax quality is there to suggest to the reader a tempting way of misinterpreting the model. This will highlight the distinctive character of the model in its original version, and provide an unusual example of a philosopher describing how not to read one of his own doctrines.

Content externalism about memory says that the individuation of memory contents depends on relations the subject bears to his past environment. I defend externalism about memory by arguing that neither philosophical nor psychological considerations stand in the way of accepting the context dependency of memory that follows from externalism.

We take self-governance or autonomy to be a central feature of human agency: we believe that our actions normally occur under our guidance and at our command. A common criticism of the standard theory of action is that it leaves the agent out of his actions and thus mischaracterizes our autonomy. According to proponents of the endorsement model of autonomy, such as Harry Frankfurt and David Velleman, the standard theory simply needs to be supplemented with the agent’s actual endorsement of his actions in order to make room for our autonomy. I argue that their proposal fails and that a more substanti ve enrichment of the standard theory is called for.

The modal antirealist, as presented here, aims to secure at least some of the benefits associated with talking in genuine modal realist terms while avoiding commitment to a plurality of Lewisian (or ersatz) worlds. The antirealist stance of agnosticism about other worlds combines acceptance of Lewis’s account of what world-talk means with refusal to assert, or believe in, the existence of other worlds. Agnosticism about other worlds does not entail a comprehensive agnosticism about modality, but where such agnosticism about modality is enforced, the aim of the agnostic programme is to show that it is not detrimental to our modal practices. The agnostic programme consists in an attempt to demonstrate the rational dispensability of that disputed class of modal beliefs which the agnostic eschews, but which are held by the realist and the folk. Here I attempt to motivate, describe, and illustrate such an agnostic antirealist programme in modal philosophy.
