The theory of eliminative materialism claims that as cognitive science advances, it will show that common concepts of mental states like beliefs do not actually exist. It argues that these concepts are part of a false "folk psychology" theory. However, the passage argues there are flaws in both eliminativism about propositional attitudes and qualia. Specifically, the theory theory underlying eliminativism is flawed, and propositions alone can discredit its position on philosophy of mind. This identification of flaws undermines the central thesis of eliminative materialism.
