@ Coded Logic
I don't know why you're using the term "good" or "perfect" or "biggest" when the term used in the argument is "greater".
"Good" and "perfect" only adds unnecessary complexity to the argument and "biggest" adds limitations because "big" can only be applied to material things.
Anyway we can and really do judgments of value upon everything. It's a trivial thing for humans.
Are you arguing that we can't judge some thing being greater than other thing?
Being pierced by a nail or caressed with silk makes no difference to you? Really?
And the argument it's not built upon empirically detectable properties of things because it's a deductive argument.
If it relied upon empirical conditions perceived in things then it would be an inductive argument.
And we can say we perceive value in things by using pure deduction.
