What kind of inquiry can best help us create a good world?
Perceptual data can be contradictory itself.  Look at Descartes' experiment with the three bowls of water - one "cold" on "hot" and one "lukewarm".  Desartes excperienced "hot" and "cold" at the same time in the same bowl of water. 

Not everyone would agree that man is "an autonomous thinking volitional being"  and there is no "objective standard of value which is a man's life". 

And all morality is subjective.  There is nothing that has ever been a universal ban - many cultures have praticed cannibalism, rape, incest, some cultures still practice female genetallia mutilation.    Many cultures have practices that other cultures would consider unethical.
