Yes; exactly. If no universals exist outside of the mind then the truth or falsity of a proposition follows from the definitions and/or assumptions upon which it is based.

Thank you for your reply!

Since I am not a Nominalist, the universals I have used (in this case, mathematical structures such as pi) exist outside of anyone's mind. It seems to me a Nominalist's propositions would have to be based on his own mental abstractions. Your original statement and its rephrasing would apply in either case (Nomalist or Realist):
1. its utility follows from its definitions 2. the truth or falsity of a proposition follows from the definitions and/or assumptions upon which it is based
IMHO, if the definitions or assumptions are personal imaginings (such as an extreme, a man thinking he's Napoleon) any conclusions therefrom are likely imaginings as well.
