`Hookway has written an interesting and important book. It is interesting because it casts the challenge of skepticism in a new light through relating to rational autonomy. It is an important book because it is free of glibness in recognising the full force of sceptical challenge.' - Robert J. Fogelin, Philosophy and Phenomenological Research`In his clearly written, carefully signposted study, Christopher Hookway canvasses the history of scepticism, and offers his own view of how we should respond.' - A.C. Grayling, TLS
