The article investigates which epistemological considerations justify how religious life fits into the school life, and examines the debate on the participation of religiosity in the education system. I do this, first, by addressing the pedagogical implications of the distinction between public and private as maintained by Richard Rorty and, second, by reconsidering the pluralist metaphysics held by William James as an alternative path to understanding and re-addressing the question of religious life in school life. The article analyzes how the strict separation of projects of individual self-creation and the public sphere, as defended by Rorty, poses problems in implementing pluralism in democratic societies and their educational institutions.
