Property counterparts and natural class trope nominalism

'Natural class' trope nominalism makes a trope's being of a certain sort--its nature--a matter of its membership in a certain natural class of actual tropes. It has been objected that on this theory had even a single member of the class of red tropes not existed, for example, then the type 'being red' would not have been instantiated and nothing would have been red. I argue that natural class trope nominalism can avoid this implication by way of counterpart theory as applied to properties.
