The reason we are even still discussing these issues thousands of years after they were first raised, is because there is no right answer. No, It's closer to the reason people are still debating evolution. Every first year philosophy student tries to reconstruct ethics (and philosophy in general) from scratch rather than reading those who came before. Every major philosophy since Descartes does the same. The real problem with any kind of philosophy is first principles. To go anywhere you have to accept some, and people keep picking their own. Stick with some long enough, and you'll get somewhere. You answers will be contingent, but definite.
