I agree there are concepts like "light of frequency in [this range] or [that range]" which can be determined independantly of human perception, but is only singled out as a relevant concept worth paying attention to because we happen to perceieve it directly.
suppose that deciding whether something is moral or not involves solving some big intractable NP-complete problem
To some extent that is what we DO have, assuming people agree more-or-less on principles like "people having jobs, income, food, shelter, etc is good" but disagree about economic policies will bring that about. Which may be what you meant :)
