Like dreaming, hallucination has been a formative trope for modern philosophy. The vivid, often tragic, breakdown in the mind’s apparent capacity to disclose reality has long served to support a paradoxical philosophical picture of sensory experience. This picture, which of late has shaped the paradigmatic empirical understanding the senses, displays sensory acts as already complete without the external world; complete in that the direct objects even of veridical sensory acts do not transcend what we could anyway hallucinate. Hallucination is thus (...) the mother of Representationalism, which insists that it is mental intermediaries that make other.. (shrink)

Sydney Shoemaker has reconciled a broadly functionalist and materialist conception of the mind with what he calls “the common-sense view‘ of the inverted spectrum. This paper explores Shoemaker’s articulation and defence of the common sense view, and the conception of the content of qualitative experience the lies behind it. It examines the Frege-Schlick view, and a counterargument that Shoemaker uses to raise a prima facie problem for the view he is defending. It is argued that when Shoemaker’s account of qualia (...) is developed in response to the paradox, it loses its intuitive appeal and its claim on the label “common-sense view‘. (shrink)

Most people will agree that if my brain were made to have within it precisely the same pattern of activity that is in it now but through artificial means, as in its being fed all its stimulation through electrodes as it sits in a vat, an experience would result for me that would be subjectively indistinguishable from that I am now having. In ‘The Story of a Brain’ I ask whether the same subjective experience would be maintained in variations like (...) these: The hemispheres are in different vats but interacting with each other through radio transmission. Smaller chunks - and eventually the individual neurons - are interacting in this way. The hemispheres or the smaller chunks undergo internally the same pattern of activity but without interacting with each other. (shrink)
