Abstract

Defenses of realist reductionism may involve petitio principii by a tacit and inadvertent reintroduction of naïve realism through continued supposition of stimulus and sensory fields' conflation. The legitimate meaningfulness of identity statements involving scientific discoveries is examined, as are their illicit or gratuitous expressions. While experimental psychological data has a role to play in refutation of direct realism, we should not underestimate the ingenuity of its proponents' extenuations , hence the need for emphasizing the logic of perceptual processes for conclusive refutation of philosophic realism. A further instance of Paul Churchland's misinterpretation of psychophysical correspondence as intertheoretic identification is given, concerning Edwin Land's retinex theory of color vision
