## Description

On Certainty (Harper Perennial Modern Thought) : Wittgenstein, Ludwig: desertcart.co.uk: Books

Review: This review is somewhat premature as I have only read this book twice and need to read it twice more to begin to penetrate its real value. Even as a layman, though, I can appreciate the confidence of the voice here.
Review: This should be the central work of modern epistemology
