Abstract

This essay outlines a certain 20th century Oxonian tradition in epistemology, contrasting it with another line of thought set out by Michael Ayers. The tradition begins with Cook Wilson and the idea that knowing is never having evidence, no matter how strong. It takes a turn in J.L. Austin, introducing two ideas into philosophy: disjunctivism and occasion-sensitivity. The last section considers whether either can really live without the other. The first part of the essay is a general consideration of the relation between two forms of awareness: perceptual, and ‘propositional’, and of how the first may furnish proof of the second. The second part considers Ayers’ view of the relation, particularly as expressed in his idea of primary and secondary knowledge, and its relation to disjunctivism about knowledge.
