Conceivability and De Re Modal Knowledge

The paper presents a dilemma for both epistemic and non‐epistemic versions of conceivability‐based accounts of modal knowledge. On the one horn, non‐epistemic accounts do not elucidate the essentialist knowledge they would be committed to. On the other, epistemic accounts do not elucidate everyday life de re modal knowledge. In neither case, therefore, do conceivability accounts elucidate de re modal knowledge.
