Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind. Others are impressed by arguments suggesting that the meaning of our words "just ain't in the head", and hold that this externalism about meaning carries over into an externalism about mind. We propose to pursue a third position. We advocate a very different sort of externalism: an _active externalism_ , based on the active role of the environment in driving cognitive processes.

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.

In this paper, I credit Quine with having implicitly held a view I had long urged on him: externalism. Quine was the first fully to recognize that all there is to meaning is what we learn or absorb from observed usage. This entails the possibility of indeterminacy, thus destroying the myth of meanings. It also entails a powerful form of externalism. There is, of course, a counter-current in Quine's work of the mid century: the idea of stimulus meaning. Attractive as this choice of empirical base is compared to such options as sense data, appearances, and percepts, it has serious difficulties. In general, an externalism which ties the contents of observation sentences and perceptual beliefs directly to the sorts of situations that usually make them true is superior to those forms of empiricism which introduce intermediaries between word and object.

Most current theories of meaning and mental content accept externalism. One of its forceful exponents is Ruth Garrett Millikan. She argues that externalism leads to the abandonment of "the last myth of the given", that is, of the idea that identity of meaning and mental content is somehow unproblematically given to us, and that we can easily recognize the sameness of meaning and mental content. If one refuses such a "mythical" giveness or meaning rationalism, one has to admit that there is no logical possibility known a priori . The paper tries to show that even if one abandons meaning rationalism one can still hold that there are logical possibilities known a priori . The claim is defended by arguing that a priori knowledge is not completely independent from experience and does not demand the absolute transparency of meaning from the first-person point of view. A priori knowledge requires only a priori justification, that is, such a justification that is based merely on relations between meanings or contents.

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.

Ever since Putnam and Burge launched their respective attacks on individualist accounts of meaning the individualist has felt squeezed for space.1 Very little maneuvering room, it seems, is left for the philosopher who wants to deny that meaning and mental content depend on the speaker's social environment. One option, popular amongst individualists, is to grant that reference is socially determined but argue that there is nevertheless a notion of meaning or content that can be understood individualistically. That is, the individualist can opt for a.

Semantic externalism in contemporary philosophy of language typically – and often tacitly – combines two supervenience claims about idiolectical meaning (i.e., meaning in the language system of an individual speaker). The first claim is that the meaning of a word in a speaker’s idiolect may vary without any variation in her intrinsic, physical properties. The second is that the meaning of a word in a speaker’s idiolect may vary without any variation in her understanding of its use. I here show that a conception of idiolectical meaning is possible that accepts the “anti-internalism” of the first claim while rejecting (what I shall refer to as) the “anti-individualism” of the second. According to this conception, externally constituted idiolectical meaning supervenes on idiolectical understanding.
