To this idealism is opposed transcendental realism
In 1884, Scientific American asked and answered the famous question, “if a tree were to fall on an uninhabited island, would there be any sound?” […] “If there be no ears to hear, there will be no sound.” […]
Dolphins, for instance, hear 150–150,000 Hz oscillations, whereas humans hear in the range of 20–20,000 Hz. We perceive only as much of reality as our mechanisms of transduction, our sensory organs, afford us. The remainder, the un-transduced portion, is lost to oblivion (or to instrumentation). Transduction induces both veridical representation and editorializing on the biological value of events and objects, such as fright at the apprehension of threat. Morality, perhaps counterintuitively, begins with editorialized sensation. […]
Churchland describes her project as examining the platform upon which morality is constructed. Her thesis is that the platform is maternal attachment to young. The largest single factor in human brain evolution is our exaggerated juvenile phase, during much of which we are helpless. This surely exerted strong selective pressure for parental behavior, care for kin. Churchland argues this is the forerunner of care for kith and strangers. Haidt, drawing from cross-cultural psychology, argues that the normative bedrock is not monolithic. He proposes six innate dimensions about which we are predisposed toward moralizing: harm-care, fairness-cheating, liberty-oppression, loyalty-betrayal, authority-subversion and sanctity-degradation.
