Mind-body identity: Cross-categorial or not?

Conclusion

I have tried to accomplish two tasks in this paper. The first, and more important, is to free my defense of the mind-body identity theory against the property objection from reliance on there being categories. The second is to argue that if there are categories, Rosenbaum's objections pose no threat to principle (II), or its more plausible relative, (IV). I believe I have finished both tasks. This significantly strengthens my reasons for accepting some form of the identity theory. Of course, deciding whether it is reasonable enough to accept is a much more difficult task. But if what I have argued elsewhere is correct, that task is also completed. We should, at least at present, accept what I call the ‘neutral’ or nonreductive identity theory.
