While Chomsky subscribes to methodological naturalism, he rejects both metaphysical naturalism and an externalist conception of meaning. This chapter explores some of Chomsky's grounds for rejecting both metaphysical naturalism and meaning externalism, in particular his peculiar attitude towards ontological physicalism and his arguments for an internalist approach to meaning.

Mary knows all there is to know about physics, chemistry and neurophysiology, yet has never experienced colour. Most philosophers think that if Mary learns something genuinely new upon seeing colour for the first time, then physicalism is false. I argue, however, that physicalism is consistent with Mary's acquisition of new information. Indeed, even if she has perfect powers of deduction, and higher-level physical facts are a priori deducible from lower-level ones, Mary may still lack concepts which are required in order (...) to deduce from the lower-level physical facts what it is like to see red.

Is disagreement about consciousness largely owed to no adequate initial clarification of the subject, to people in fact answering different questions clarified as actual consciousness. Philosophical method like the scientific method includes transition from the figurative to literal theory or analysis. A new theory will also satisfy various criteria not satisfied by many existing theories. The objective physical world has specifiable general characteristics including spatiality, lawfulness, being in science, connections with perception, and so on. Actualism, the literal theory or analysis (...) of actual consciousness, deriving mainly from the figurative database, is that actual consciousness has counterpart but partly different general characteristics. Actual consciousness is thus subjectively physical. So physicality in general consists in objective and also subjective physicality. Consciousness in the case of perception is only the dependent existence of a subjective external physical world out there, often a room. But cognitive and affective consciousness, various kinds of thinking and wanting, differently subjectively physical, is internal – subjectively physical representations-with-attitude, representations that also are actual. They differ from the representations that are lines of type, sounds etc. by being actual. Thus they involve a subjectivity or individuality that is a lawful unity. Actualism, both an externalism and an internalism, does not impose on consciousness a flat uniformuity, and it uniquely satisfies the various criteria for an adequate theory, including naturalism. Actual consciousness is a right subject and is a necessary part of any inquiry whatever into consciousness. All of it is a subject for more science, a workplace. There is no unique barrier or impediment whatever to science, as often said, no want of understanding of the mind-consciousness connection, no known unique hard problem of consciousness, no insuperable difficulty having to do with physicality and the history of science, no arguable ground at all of mysterianism.

Might the world be structured, as Leibniz thought, so that every part of matter is divided ad infinitum? The Physicist David Bohm accepted infinitely decomposable matter, and even Steven Weinberg, a staunch supporter of the idea that science is converging on a final theory, admits the possibility of an endless chain of ever more fundamental theories. However, if there is no fundamental level, physicalism, thought of as the view that everything is determined by fundamental phenomena and that all fundamental phenomena (...) are physical, turns out false, for in such a world, there are no fundamental phenoma, and so fundamental phenomena determine nothing. While some take physicalism necessarily to posit a fundamental level, here I present a thesis of physicalism that allows for its truth even in an infinitely decomposable world. (shrink)
