Abstract
Fear is a preventer, sometimes robustly so. When fear robustly prevents, it changes or diminishes what an agent is able to do. Various popular conceptions of fear focus on its negative role: fear sometimes prevents us from acting as we should, as in certain cases of akrasia. But by the same token, fear sometimes prevents us from acting as we shouldn’t, as in certain other cases of inverse akrasia. We end with a plea on behalf of fear, both in light of its preventing role and its broader connection to other ways we express concern, in particular, to hope.
