"With these words Bertrand Russell introduces what is indeed a revolutionary book. Taking as his starting point the irrationality of the world, he offers by contrast something 'wildly paradoxical and subversive' - a belief that reason should determine human actions. Unwittingly foreseeing the horrors that resulted in the ensuing years from the irrational passions of religious and political beliefs, it is no wonder that Sceptical Essays has never been out of print since its first publication 1928." Today, besieged as we are by the numbing onslaught of twenty-first-century capitalism, Russell's defence of scepticism and independence of mind is as timely as ever. In clear, engaging prose, he guides us through the key philosophical issues that affect our daily life - freedom, happiness, emotions, ethics and beliefs - and offers no-nonsense advice. What would be the effect, he asks his readers with playful irony, 'of a spread of rational scepticism?'.
