Mad Travelers tells of a mental illness that was born, flourished and virtually died away within the brief span of twenty-three years...Hacking has written a fascinating book...there is probably no wiser or more intriguing guide to such topics.
   --Louis A. Sass, Times Literary Supplement

Not only does [Hacking] write with rare sympathy and elegance, he draws on his background in philosophy to make this byway from the history of medicine full of resonance.
   --Rosemary Dinnage, New York Review of Books
