This contribution to the symposium on Annalisa Coliva’s Extended Rationality is largely sympathetic with the moderate view of the structure of epistemic warrant which is defended in the book. However, it takes issue with some aspects of Coliva’s Wittgenstein-inspired ‘hinge epistemology’, focussing especially on her conception of propositional warrant, her treatment of epistemic closure, her antirealist conception of truth, and the significance of her answer to so-called Humean scepticism.
