Abstract
The aim of this paper is to present a reflection on the idea of religiousness or religious sentiment in Benjamin Constant de Rebecque and the importance of this in free societies. For the author, the religious sentiment avoids the evils of selfishness and individualism and, at the same time, the dangers of political despotism and religious. In this sense, religion is seen as necessary to free societies. However, it must be separated from the priestly factions. Constant presents a strategy of fusing a perspective of Enlightenment - with the concepts of progress and civilization - with aspects of the thought of Edmund Burke who advocated a more local interest. Thus, the "Greeks" - an "ideal type" avant la lettre - are presented with real people in history, which can help to think of our civilization. An "intermediate political principle", avoiding the excesses of philosophical abstraction.
