Philosophical 'thought experiments' invoking inverted spectra,
zombies, et cetera suggest that conscious sensations have no
function, and psychological studies finding no correlation between
vivid visual imaging and visual problem solving suggest that
conscious images have no function. Furthermore, both philosophical
and psychological theories suggest that self-consciousness has no
function. Countering such suggestions, the post-Darwinian
double-aspect theory which Professor Robert Kunzendorf's introduces
in the first chapter of his monograph On the Evolution of Conscious
Sensation, Conscious Imagination, and Consciousness of Self points
to evolutionary functions of certain sensations, youngling vivid
images, and self-consciousness. Kunzendorf's second chapter
presents evidence that the most primitive sensation-pain, the
subjective aspect of free nerve endings or nociceptors-has a
survival-promoting function. But as the pressure nociceptor mutates
into a touch receptor, the heat nociceptor into temperature
receptor, and the chemical nociceptor into a taste receptor, the
painful qualia of these nociceptors evolve respectively into touch
sensation, temperature sensation, or taste sensation-painless
sensations that add no survival benefit to their receptor's
physical aspect. Building on evidence that retinal receptors
embodying visual qualia evolved from primitive eyespots responsive
to injurious 'heat at a distance' or painful light, the third
chapter presents evidence that visually imagined sensations are the
subjective qualities of retinal receptors that are corticofugally
innervated in warm-blooded animals-for the developmental purpose of
testing cortically hypothesized sensory-motor rules that have
greater survival value than cold-blooded stimulus-response
associations. The fourth and final chapter focuses on
self-conscious reality-testing and on visuo-spatial
self-conceptualization, and presents evidence that such
manifestations of self-awareness evolve only in those warm-blooded
animals whose rule-developing youth lasts two years or longer-that
is, those mammals and birds whose survival during the imaginal
testing of rules is subjected to prolonged risk if
self-consciousness that one is imaging sensations (rather than
perceiving sensations) is absent.
