If knowing what “should” means helped something, then knowledge of a definition could lead to real actionable information. This seems, on the face of it, absurd.
I think either:
“XYZ things are things that maximize utility”
or:
“XYZ things are things that you should do”
can count as a definition of XYZ, but not both, just as:
“ABC things are red things”
pr
“ABC things are round things”
can count as a definition of ABC things, but not both. (Since if you knew both, then you would learn that red things are round and round things are red.)
