Quinton with "The foundations of knowledge" in collection cited by Grice

-- In Prolegomena to Logic and Conversation, Grice refers to Williams/Montefiore, "British Analytic Philosophy" for the essay by Searle, "Assertions and aberrations". That excellent collection also features an survey and critique of foundationalism by Quinton, The foundation of knowledge. It may relate to Grice's point on the implicatures of 'know' in the third William James Lecture, where Grice considers a version of the 'causal theory'.
