Not quite. They don't go all the way to completing an ought statement, as this doesn't solve the Is/Ought dichotomy. They are logical transformations that make applying our values to the universe much easier.

"X is unjust" doesn't quite create an ought statement of "Don't do X". If I place value on justice, that statement helps me evaluate X. I may decide that some other consideration trumps justice. I may decide to steal bread to feed my starving family, even if I view the theft as unjust.
