Coliva, Annalisa, and . Extended Rationality: A Hinge Epistemology

2015, Basingstoke: Palgrave Macmillan.

Publisher’s Note: Extended Rationality: A Hinge Epistemology provides a novel account of the structure of epistemic justification. Its central claim builds upon Wittgenstein’s idea in On Certainty that epistemic justifications hinge on some basic assumptions and that epistemic rationality extends to these very hinges. It exploits these ideas to address major problems in epistemology, such as the nature of perceptual justifications, external world skepticism, epistemic relativism, the epistemic status of basic logical laws, of the Principle of the Uniformity of Nature, of our belief in the existence of the past and of other minds, and the nature of testimonial justification. Along the way, further technical issues, such as the scope of the Principle of Closure of epistemic operators under known entailment, the notion of transmission failure, and the existence of entitlements are addressed in new and illuminating ways.

Comment: In this interesting book, Annalisa Coliva develops an account of the structure of justification inspired by Wittgenstein's epistemology (Ch.1-3), argues a constitutivism about epistemic rationality (Ch.4) and reveals its significance for many contemporary problems (Ch.5). Ch.1 involves a overview of three dominant views of perceptual warrants: liberalism, conservativism and moderatism, so it could be a useful reading material for teachings on epistemic justification and perceptual warrant. Ch.4 can be used as a further reading for topics on epistemic rationality, Wittgenstein's epistemology and external world skepticism.
