The post-Darwinian double-aspect theory that Professor Robert Kunzendorf's introduces in 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.
Freud attributed uncovered incest, initially, to real abuse dissociated from self-consciousness, and later, to wishes repressed from consciousness. Dissociation is preferred on theoretical and empirical grounds. Whereas dissociation emerges from double-aspect materialism, repression implicates Cartesian dualism. Several studies suggest that abnormal individuals dissociate trauma from self-conscious source-monitoring, thereby convincing themselves that the trauma is imaginary rather than real, and re-experience the trauma as an unbidden image.
