  1. W. R. Webster (2006). Human Zombies Are Metaphysically Impossible. Synthese 151 (2):297-310.
    Chalmers (The Conscious Mind, Oxford Unversity Press, Oxford 1996) has argued for a form of property dualism on the basis of the concept of a zombie (which is physically identical to normals), and the concept of the inverted spectrum. He asserts that these concepts show that the facts about consciousness, such as experience or qualia, are really further facts about our world, over and above the physical facts. He claims that they are the hard part of the mind-body issue. He (...)

  2. W. R. Webster (2003). Revelation and Transparency in Colour Vision Refuted: A Case of Mind/Brain Identity and Another Bridge Over the Explanatory Gap. Synthese 133 (3):419-39.
    Russell (1912) and others have argued that the real nature of colour is transparentto us in colour vision. It's nature is fully revealed to us and no further knowledgeis theoretically possible. This is the doctrine of revelation. Two-dimensionalFourier analyses of coloured checkerboards have shown that apparently simple,monadic, colours can be based on quite different physical mechanisms. Experimentswith the McCollough effect on different types of checkerboards have shown thatidentical colours can have energy at the quite different orientations of Fourierharmonic components but (...)

  3. W. R. Webster (2002). A Case of Mind/Brain Identity: One Small Bridge for the Explanatory Gap. Synthese 131 (2):275-287.
    Based on the technique of pressure blinding of the eye, two types of after-image (AI) were identified. A physicalist or mind/brain identity explanation was established for a negative a AI produced by moderately intense stimuli. These AI's were shown to be located in the neurons of the retina. An illusory AI of double a grating's spatial frequency was also produced in the same structure and was both prevented from being established and abolished after establishment by pressure blinding, thus showing that (...)

  4. W. R. Webster (2002). Wavelength Theory of Color Strikes Back: The Return of the Physical. Synthese 132 (3):303-34.
    There have been a number of criticisms, based on visual processes, of the Australian view that colour is an objective property of the world. These criticisms have led to subjective theories about colour. These visual processes (metamers, retinex theory, opponent processes, simultaneous contrast, colour constancy, subjective colours) have been examined and it is suggested that they do not carry their supposed critical weight against an objective theory. In particular, it is argued that metamers don''t occur in nature and primate colour (...)
