That's trivially false. For example, I BELIEVE that I'm smug right now. How could a person ever form a belief like that except based on their feelings?
But feelings can also be used for more than just forming beliefs about feelings themselves. For example, if someone considers (non-statutory) raping a child and then feels bad most normal humans would take that as an indication that maybe (non-statutory) raping a child is bad.
Sure, a human's feelings could mislead them regarding normative beliefs, but can't feelings at least be a reasonable indicator of normative truths?
I'm curious, if we don't define good and bad in terms of the feelings of a human who is thinking objectively, then how else are we supposed to define good and bad? Can you come up with a complete definition of good and bad which matches people's usage of the term, but which isn't based on feelings in one way or another?
