usefulness is a pragmatic attribute, it does not by itself say that something really exist in reality, unless you believe that everything that is useful exists.

usefulness is a pragmatic attribute, it does not by itself say that something really exist in reality, unless you believe that everything that is useful exists. I think the OP do not believe that everything that is useful exists in physical reality, therefore seeing four tables does not mean that fours exists in physical reality separated from tables or other objects. So you are probably using different metaphysics.. But sure, since the days of William of Occam pragmatic metaphysics have been popular, but again popularity does not necessary prove something is right. Just explaining both sides of the argument here and trying to resolve the potential missunderstandings
