This paper argues for a completely universal scepticism, according to which no beliefs at all are justified to the least degree. The argument starts with a version of the Agrippan trilemma, according to which, if we accept that a belief is justified, we must choose between foundationalism, coherentism of a particular sort, and an infinite regress of justified beliefs. Each of these theories is given a careful specification in terms of the relationship of “justifiedness in p depending on justifiedness in (...) q”. It is then argued that no beliefs – not even beliefs about phenomenal experiences – are foundational in the required way. Both coherentism and infinitism are untenable, since, since they face various objections, most significantly the objection that acceptance of either would commit one to allowing that all beliefs were justified. Because the three possible accounts of justificational structure all fail radically, it is concluded that no beliefs are justified. (shrink)

It is commonly thought that the requirements of inferential justification are such that necessarily the process of inferentially justifying a belief will come to an end. But, If this is so, We should be able to pick out those requirements of justification which necessitate an end to the justification process. Unfortunately, Although there is nearly unanimous agreement as to the need for such an end, It is by no means clear which particular requirements of justification impose this need. I examine (...) and criticize several seemingly plausible ways of showing that regresses of inferential justification are impossible and then propose two requirements of inferential justification which, I argue, Are sufficient to show the impossibility.
