Here's a very interesting link to a panel discussion on Quine's views about language, science and philosophy. This particular segment (its broken into nine and they are all worth watching, preferably in sequence) involves Dennett (one of the panelists) asking Quine to clarify his position vis a vis behaviorism: http://www.youtube.com/watch?v=WumCK5cxrFQ

Dennett poses the question to Quine as a matter of Quine's distinguishing the relationship of his views on language and meaning, which Quine acknowledges as consistent with behaviorism, as to whether they are more compatible with a Skinnerian approach to behaviorism or the kind of behaviorism Wittgenstein is often seen as representing. (In the literature Wittgenstein's later position on meaning is sometimes thought of as "logical behaviorism" as opposed to a methodological and/or metaphysical sort which, latter, presumably denies the existence of mental objects in any sense whatsoever.) This is an interesting exchange in light of the frequent debates and disagreements here over whether Wittgenstein was a behaviorist and, if so, which type, and whether Dennett effectively is, and so can be construed as denying the existence or reality of what we call our "experiences" in his attempts to "explain" consciousness.
