"[In a post-Darwinian utopia,] our own 'ordinary' consciousness may be unmasked as a shallow and uninteresting vehicle of malaise whose properties we were physiologically incapable of recognising 'from the inside'. At present, however, we lack the neural substrates of a capacity to set archaic consciousness in a pre- and post-Darwinian context. Or as Einstein says: 'What does the fish know of the sea in which it swims?'
Physical science, the scientific rationalist may freely go on to admit, has not yet definitively settled on the ultimate ontological furniture of the universe. There is plenty of theoretical and experimental work to be done investigating whether its ontological primitives are particles, fields, probability waves, loops, superstrings or whatever. The relationships between these primitives still tantalisingly awaits a complete and unified mathematical description as well. But whatever really exists e.g. macroscopic objects, itself supervenes on mind-independent configurations of these ontologically basic primitive entities, events or properties. Values, on the other hand, are merely mind-dependent subjective fictions. We don't read them off the world, but project them on to it."
