Full Idea
Foundationalism can get rid of the regress argument with one of three types of belief: those justified by something other than beliefs, those which justify themselves, or those which need no justification.
Gist of Idea
Foundations are justified by non-beliefs, or circularly, or they need no justification

A Reaction
A nice clear trilemma, and none of them will do, which is why foundationalism is false. I vote for Davidson's view, that only a belief can justify another belief.
