A seber biography of a sober man -- a great political and social thinker and humanitarian. ""Citizen of the world"" -- he fought for liberty, universal peace and the rights of man. Pearson has endeavored to show us the man rather than his achievements in the realm of political philosophy, although the latter is glimpsed. For the most part, this is the story of his personal ups and downs in his efforts to achieve political tolerance and freedom in America, England and France. Long citations from his essays give a clear idea of his work. Not a glamorous figure -- as a personality. His life, aside from his political combats and defeats is singularly unromantic. But this is good solid and adequately scholarly work, of limited interest for those concerned with the subject and period.
