 For the Replacement Naturalist, in short, the only sound reason to prefer a proposed conceptual analysis is not because it seems intuitively obvious, but because it earns its place by figuring in successful a posteriori theories of the world. Philosophy qua conceptual analysis and intuition-pumping should be abandoned in favor of empirical science; philosophy is simply the more abstract and reflective part of empirical science and lays claim to no distinctive methods or body of knowledge.
