Problem of Other Minds - Soft Materialist Viewpoint

Soft Materialist Viewpoint

Counter to the reductionist argument would be a more biological theory (and somewhat materialistic viewpoint). Take the eye and the perception of color. The light-sensing cone cells of the retina that respond to the portion of the electromagnetic spectrum designated as red are tuned similarly in every person tested, so we might expect all people to experience red in the same way. However, we also know that some people are missing certain (or all of) types of cone cells in the eye; thus giving rise to color blindness and other such ocular variances. Similarly, differences in the distribution of brain cells and dendritic connections (among many other potential variances) could give rise to different mental states for the same stimulus. Cross-culturally, when people have a word for red, they agree with other cultures on which wavelengths of light best fit the term "red" (the same wavelengths that primarily excite the cone cells which detect red, and the red/green channel to the brain). Yet even if human eyes and brains may be built in such a way that the same wavelengths stand out for everybody, still it is conceivable that for different individuals these wavelengths could evoke experiences that differ. In particular, one external stimulus may give different experiences to the same individual according to which eye is used.

Famous quotes containing the words soft and/or materialist:

    The soft complaining FLUTE
    In dying Notes discovers
    The Woes of hopeless Lovers,
    Whose Dirge is whisper’d by the warbling LUTE.
    John Dryden (1631–1700)

    There are two equal and opposite errors into which our race can fall about the devils. One is to disbelieve in their existence. The other is to believe, and to feel an excessive and unhealthy interest in them. They themselves are equally pleased by both errors and hail a materialist or a magician with the same delight.
    —C.S. (Clive Staples)
