The Party of Humanity

The nine related essays in The Party of Humanity fall into three divisions: three are on Voltaire, presenting the great philosophe as a tough-minded, realistic man of letters who tried to reshape his world, rather than as a merely brittle and shallow wit. Then, three essays discuss the French Enlightenment as a whole and seek for the unity underlying the diversity of tempers and attitudes among its leaders. The last three, which include Mr. Gay's well-known critique of Carl Becker's The Heavenly City of the Eighteenth Century Philosophers, challenge some widely accepted views of the Enlightenment. The longest chapter here is a detailed examination of Rousseau and his reputation among his interpreters.

What all nine essays have in common, apart from their portrayal of the philosophes as serious and engaged partisans of humanity, is that they are essays in the social history of ideas; they all treat ideas as inseparable from the specific social and cultural setting from which they emerge, and which they affect.
