I consider the support variously offered for the remark at Philosophical Investigations 246: ‘It can’t be said of me at all (except perhaps as a joke) that I know I am in pain.’ Against the first sort of argument to be found in Wittgenstein and the literature I offer cases in which I learn of pain. Against the second sort of argument I develop the case in which I am persuaded by compelling evidence that I am, contrary to what I imagined, still in an emotional pain about N. I then consider the counter-argument that the mix of sensation and emotion in my second case makes it irrelevant as a criticism of Wittgenstein, but argue that the reverse holds. That ‘sensation’ is quite separate from ‘emotion’ is a Cartesian Mistake which is, I argue, implicit in Wittgenstein’s discussion of ‘I know I am in pain’.

Painful stimuli evoke functional activations in the cortex, but electrical stimulation of these areas does not evoke pain sensation, nor does widespread epileptic discharge. Likewise, cortical lesions do not eliminate pain sensation. Although the cortex may contribute to pain modulation, the planning of escape responses, and learning, the network activity that constitutes the actual experience of pain probably occurs subcortically.

Functionalism cannot accommodate the possibility of mad pain—pain whose causes and effects diverge from those of the pain causal role. This is because what it is to be in pain according to functionalism is simply to be in a state that occupies the pain role. And the identity theory cannot accommodate the possibility of Martian pain—pain whose physical realization is foot-cavity inflation rather than C-fibre activation (or whatever physiological state occupies the pain-role in normal humans). After all, what it is to be in pain according to the identity theory is to be in whatever state that occupies the pain role for us.
