Exact definitions are easy to come by, so long as you are not bothered about correctness. Let morality=42, for instance. If you are bothered about correctness, you need to solve metaethics, the question of what morality is, before you can exactly and correctly define "morality".

I can understand the impatience with philosophy -- "why can't they just solve these problems"--because that was my reaction when I first encountered it some 35 years ago. Did I solve philosophy? I only managed to nibble away at some edges. That's all anyone ever manages.
