Daniel Dennett's 'Quining Qualia' (http://ase.tufts.edu/cogstud/papers/quinqual.htm) is taken ('round these parts) to have laid the theory of qualia to rest. Among philosophers, the theory of qualia and the classical empiricism founded on it are also considered to be dead theories, though it's Sellers "Empiricism and the Philosophy of Mind" (http://www.ditext.com/sellars/epm.html) that is seen to have done the killing.
