Representational theorists identify experiences’ phenomenal properties with their representational properties. Qualia theorists reject this identity, insisting that experiences’ phenomenal properties can come apart from and completely outrun their representational properties. Qualia theorists account for phenomenal properties in terms of “qualia,” intrinsic mental properties they allege experiences to instantiate. The debate between representational theorists and qualia theorists has focused on whether phenomenal properties really can come apart from and completely outrun representational properties. As a result, qualia theorists have failed (1) to explain how experiences owe their phenomenal properties to their instantiation of qualia and (2) to clarify the nature of subjects’ epistemic access to qualia. I survey qualia theorists’ options for dealing with each issue and find them all wanting.

Putnam and Burge have been viewed as launching a joint attack on individualism, the view that the content of one's psychological state is determined by what is in the head . Putnam argues that meanings are not in the head while Burge argues that beliefs are not in the head either, and both have come up with convincing arguments against individualism. It is generally conceived that Putnam's view is a version of physical externalism, which argues that factors in the physical environment play a role in determining the meanings of natural kind terms. Burge, on the other hand, is regarded as following up Putnam's argument to bring in factors in the social environment for the determination of belief. Burge's view has been commonly referred to as 'social externalism.' The general consensus in the field is that physical externalism and social externalism are compatible views. Furthermore, both Putnam and Burge seem to endorse each other’s position for the most part. In this paper, however, I shall argue against this general view to show that the two theories are deep down incompatible.

In “The Meaning of ‘Meaning’” Putnam argues, among other things, that “‘meanings’ just ain’t in the head”. Putnam’s central arguments in favor of this conclusion are unsound. The arguments in question are the famous intra‐world Twin Earth arguments, given on pages 223‐ 227 of the article in question.

A celebrated problem for representationalist theories of phenomenal character is that, given externalism about content, these theories lead to externalism about phenomenal character. While externalism about content is widely accepted, externalism about phenomenal character strikes many philosophers as wildly implausible. Even if internally identical individuals could have different thoughts, it is said, if one of them has a headache, or a tingly sensation, so must the other. In this paper, I argue that recent work on phenomenal concepts reveals that, contrary to appearances, this standard conjunction of externalism about content and internalism about phenomenal character is ultimately untenable on other models of phenomenal character as well, including even “qualia realism.” This would be significant for a number of reasons. The first is patent: it would undermine a primary objection to representationalism. The fact that representationalism is incompatible with the conjunction would be no serious problem for representationalism if no other plausible model of phenomenal character is compatible with it. The second is that the many philosophers who embrace the conjunction would be forced to abandon one of the two views; externalism would be true either of both content and phenomenal character, or of neither. Likewise, those philosophers who have taken a stance on only one of the two internalism/externalism debates would have to be seen as thereby committed to a particular stance on the other. The third reason stems from the fact that qualia realism typically goes hand in hand with internalism about phenomenal character. To the extent that it does, my argument would reveal that qualia realism is itself in tension with externalism about content. This would perhaps be the most surprising result of all.

Qualia internalism is the thesis that qualia are intrinsic to their subjects: the experiences of intrinsic duplicates (in the same or different metaphysically possible worlds) have the same qualia. Content externalism is the thesis that mental representation is an extrinsic matter, partly depending on what happens outside the head.¹ Intentionalism (or representationalism) comes in strong and weak forms. In its weakest formulation, it is the thesis that representationally identical experiences of subjects (in the same or different metaphysically possible worlds) have the same qualia.².
