Abstract

This essay is concerned with Bernard Williams’ contention in _Ethics and the Limits of Philosophy_ that, in ethics, reflection can destroy knowledge. I attempt to defend this contention from the charge of incoherence. I do this by taking seriously the idea that ethical knowledge is knowledge from an ethical point of view. There nevertheless remains an issue about whether the contention is consistent with ideas elsewhere in Williams’ own work, in particular with what he says about knowledge in _Descartes_. In an earlier essay I argued that it is not. In a subsequent essay I indicated that I had changed my mind and gave a more sympathetic account of Williams’ contention. In this essay I set out the issues and say some more about my change of mind.
