Secularism is often imagined in Thomas Jefferson's words as 'a wall of separation between Church and State'. This book moves past that standard picture to argue that secularism is a process that reshapes both religion and politics. Borrowing a term from religious traditions, the book goes further to argue that this process should be understood as a process of conversion. Matthew Scherer studies Saint Augustine, John Locke, John Rawls, Henri Bergson and Stanley Cavell to present a more accurate picture of what secularism is, what it does, and how it can be reimagined to be more conducive to genuine democracy.
