ABSTRACT
Regressive arguments for ignorance are inspired by the old sceptical idea that an infinite regress of justification is both necessary for knowledge and at the same time impossible. Their distinguishing feature is that they employ a sense of ‘knowledge’ which is governed by this condition: For any person S and any proposition p, if S knows that p only because he believes another proposition which is evidence for p, then he already knows that other proposition. Any such sense of ‘knowledge’ I call regressive, and a regressive argument for ignorance I define as one which employs a regressive sense of ‘knowledge’. In this chapter I look for sound and sceptical regressive arguments for ignorance which pass the negation test.
