The academic world has been plagued in recent years by scepticism about truth and knowledge. Paul Boghossian, in his long-awaited first book, sweeps away relativist claims that there is no such thing as objective truth or knowledge, but only truth or knowledge from a particular perspective. He demonstrates clearly that such claims don't even make sense. His short, lucid, witty book shows that philosophy provides rock-solid support for common sense against the relativists, and will prove provocative reading throughout the discipline and beyond.
