Epistemology
Audi has defended a position he calls "fallibilistic foundationalism." He thinks that the foundationalist response is the only tenable option of the epistemic regress argument. This states that if every belief has to be justified by some other, then the only options are four: infinite regress, circularity, stopping at a belief that isn't knowledge, and stopping at a basic belief that is itself justified. If the only alternative is the fourth, then if one has knowledge, one has foundational knowledge. Audi considers that foundationalism is usually taken to be infallible. That is, it is normally associated with the view that knowledge is founded on basic beliefs that are axiomatic and necessarily true, and that the rest of knowledge is deduced from this set of beliefs. Audi thinks that foundationalism may be fallible, in the sense that the suprastructure of beliefs may be derived inductively from the basic beliefs, and hence may be fallible. He also thinks that basic beliefs need not be necessary truths, but merely have some structure which makes epistemic transition possible. For example, the belief that one is in the presence of an object arises causally from visual perception.
