It is my contention that a number of prominent commentators on the problem of radical epistemological scepticism labour under a certain erroneous conception of what this problem involves. In particular, I argue that they tend to both underestimate and overestimate the issue that faces them. On the one hand, they are confused as to what would constitute a satisfactory answer to the sceptic. On the other, they concede far too much to the sceptic by failing to recognise that there are a number of defensive moves available to them, especially insofar as they endorse a version of epistemological externalism. In order to illustrate these claims, I focus upon Edward Craig's analysis of knowledge that, by his own admission, is unable to satisfactorily answer the challenge of radical scepticism.
