A Reaction

In relation to the quest of Sextus Empiricus to find the 'criterion' of knowledge, this makes Kant a sceptic. It certainly seems to rule out any foundationalist view of knowledge. (Clearly Kant believes that an account of knowledge is possible).

Beliefs can only be infallible by having almost no content [Dancy,J]
Strong justification eliminates error, but also reduces our true beliefs [Williams,M]
Foundationalists are torn between adequacy and security [Williams,M]
Foundationalism is wrong, because either all beliefs are prima facie justified, or none are [Pollock/Cruz]
