Did mathematical knowledge require the existence of numbers as objective and non-physical entities?

This was based on J.P. Moreland, I want to make sure if this dealt with the one problem with physicalism. Thanks!Did mathematical knowledge require the existence of numbers as objective and non-physical entities?
Yep! Dice. (I am speaking with Grammatical inaccuracy for clarity's sake.)


Dice count. Dice add. Dice subtract. Dice gamble. Dice forms the basis of one of the most successful industries that keeps Las Vegas thriving. Dice have no numbers on them, and yet gamblers ';count'; on them.





P.S. Set Theory is Logical, not necessarily mathematical.Did mathematical knowledge require the existence of numbers as objective and non-physical entities?
No, Platonism is not necessary with set theory.





Consciousness as such seems to be a problem for physicalism, however. (source below)
Erm.





Does that have something to do with metaphysics?
