Abstract

Benjamin Constant's On Religion was a major effort to include religion within liberal political thought, insisting on the possibility of religious progress and perfectibility. It was also a major critique of Catholicism and of clericalism in any form. And it was one of the most wide-ranging comparative studies of religion since it purported to cover all religions worldwide before Christianity. Constant worked on it for most of his adult life, more than 40 years. This article traces the rise of the language of progress and perfectibility in Constant's milieu, finding roots in Rousseau, Scottish thinkers, Germans and Swiss such as Madame de Staël, Condorcet, William Godwin, and others. He also sprinkled some of his ideas about progress and perfectibility in his wide-ranging political writings. But it was in On Religion that he went into the idea of progress and perfectibility in depth, finding both a universal human need for religion and religious progress in every religion and over time. It may be true that he underestimated the possibility of regress and failure in human development, but nevertheless this work stands as a monument to liberal confidence in a better future.
