Comment on What is Metaethics?

...the way human brains are designed, thinking about your preferences can cause them to change.

If that's a definition of morality, then morality is a subset of psychology, which probably isn't what you wanted.

If that's a valid argument, then logic, mathematics, etc are branches of psychology.

Now if the thoughts people had about moral preferences that make them change were actually empirically meaningful and consistent with observation, rather than verbal manipulation consisting of undefinable terms that can't be nailed down

Are you saying there has never been any valid moral discourse or persuasion?
