Ontologically, the objective realm is primary whereas, cognitively, subjectivity is primary. The earliest conscious organisms, experiencing bodily satisfaction or dissatisfaction, did not yet apprehend the discrete, "external," objects of their external environment, the objective realm. Complex central nervous systems process sensations into perceptions, then generate concepts and thoughts. However, we do not understand how objective neurological interactions cause subjective mental processes and also do not know what would count as such an understanding.
Can a psychophysical organism understand the relationship between its physical and psychological aspects? Is trying to understand the mind-brain relationship like trying to visualize a fourth dimension or a new colour?
