General Conclusion

Some general remarks are given about methods of argument in metaphysics. The importance of indispensability arguments, and the importance of the fact that such arguments don’t succeed, is reiterated. The important point is that removing such arguments reveals heretofore hidden logical space. The very position of ontological projectivism can’t be seen unless indispensability arguments are undercut first. The fact that if certain aspects of metaphysics (such as object boundaries) are projected, then certain conceptual puzzles will arise, is also stressed. This is not itself directly an argument for object projectivism; instead, it is a valuable side-effect of arguments that don’t directly turn on conceptual puzzles. Work left for the future is described.
