Euthyphro dilemma asked for evolution.

[Angrboda]

The part of your family would explain why you wouldn't like to do it, but does it explain why you feel it is wrong?

Nature doesn't have to use the same method to support all ends. Different behaviors may be reinforced by different emotional or cognitive behaviors. When my body needs rest, I feel sleepy. When my body needs nourishment, I feel hungry. That I don't feel sleepy when I'm hungry is no indication that sleepiness or hunger indicate universal, objective truths, it simply shows that different mechanisms are employed. That I have moral feelings when I think about behaviors having a moral dimension is no different from having aesthetic feelings about aesthetic experiences, or hunger feelings leading to eating behaviors. Different in content, but not in kind.

You keep coming back to the same flawed argument. You "feel" morality is different from these other things, so you suggest we need to explain your feeling. I "feel" that AC/DC is the greatest rock and roll band ever. Does that obligate you to explain in what way they are in fact the greatest?
