> And that leads to a nastier question. Are "morals" just a subset of "feelings"? Are they also just biochemical processes? If so, first, do morals have any actual validity?

I don't believe that. I think "morals" is just a somewhat codified set of rules derived from innate feel of what's right and what not, shared by a majority of a society. Morals have no objective validity.

But that doesn't mean they are not valuable, I believe they are important for a cohesive and stable society.
