 Philosophy of science and scientific epistemology were not the only areas where neurophilosophers urged the relevance of neuroscientific discoveries for traditionally philosophical topics. A decade after Neurophilosophy’s publication, Kathleen Akins (1996) argued that a “traditional” view of the senses underlies a variety of sophisticated “naturalistic” programs about intentionality. (She cites the Churchlands, Daniel Dennett, Fred Dretske, Jerry Fodor, David Papineau, Dennis Stampe, and Kim Sterelny as examples.) But then-recent neuroscientific work on the mechanisms and coding strategies implemented by sensory receptors shows that this traditional view is mistaken. The traditional view holds that sensory systems are “veridical” in at least three ways. (1) Each signal in the system correlates with a small range of properties in the external (to the body) environment. (2) The structure in the relevant external relations that the receptors are sensitive to is preserved in the structure of the internal relations among the resulting sensory states. And (3) the sensory system reconstructs faithfully, without fictive additions or embellishments, the external events. Using then-recent neurobiological discoveries about response properties of thermal receptors in the skin (i.e., “thermoreceptors”) as an illustration, Akins showed that sensory systems are “narcissistic” rather than “veridical”. All three traditional assumptions are violated. These neurobiological details and their philosophical implications open novel questions for the philosophy of perception and for the appropriate foundations for naturalistic projects about intentionality. Armed with the known neurophysiology of sensory receptors, our “philosophy of perception” or account of “perceptual intentionality” will no longer focus on the search for correlations between states of sensory systems and “veridically detected” external properties. This traditional philosophical (and scientific!) project rests upon a mistaken “veridicality” view of the senses. Neuroscientific knowledge of sensory receptor activity also shows that sensory experience does not serve the naturalist well as a “simple paradigm case” of an intentional relation between representation and world. Once again, available scientific detail showed the naivety of some traditional philosophical projects.
