In this thought provoking Very Short Introduction, Jennifer Nagel considers the central problems and paradoxes in the theory of knowledge whilst drawing attention to the ways in which philosophers and theorists have responded to them. By exploring the relationship between knowledge and truth, and considering the problem of scepticism, Nagel introduces a series of influential historical and contemporary theories of knowledge, incorporating methods from logic, linguistics, and psychology, and using a number of everyday examples to demonstrate the key issues and debates.

And that might just be the mindset we need to rein in unsustainable development.In this thoughtful Penguin Special, Slattery traces the radicalism of classical Epicurean thought, and its popularity despite political suppression.

Might some of this treasure's fragments, painstakingly restored, reveal answers to the big questions faced in the twenty-first century?
