sentience = phenomenal consciousness
sapience = psychological consciousness
What does this distinction amount to?
“Chalmers points out that psychology and neuroscience have made significant progress toward increasing our understanding of sapience – psychological consciousness… In contrast, we seem to have made little or no progress in understanding sentience. What understanding we do have consists mainly in the discovery of brute correlation between conscious episodes and neurological events. The identification of correlation represents at most a starting point for explanation, however, not a settled goal. Unlike the case of sapience, where it is reasonable to expect incremental progress, it is hard to see what we could do to move ahead in our understanding of the basis of consciousness.” - John Heil
"… all there is to being conscious is acting and interacting intelligently in a complex environment (see e.g. Dennet 1991)."
