Abstract
Classic theories of religious toleration from the 17th century regularly made exceptions for various categories of people such as Catholics and atheists who need not be tolerated. From a contemporary perspective these may be understood as blind spots because at least some of us would argue that these exceptions were not necessary. This essay explores the toleration theories of John Milton, Benedict de Spinoza, Denis Veiras, John Locke and Pierre Bayle in order to assess whether they actually called for such exceptions and whether those exceptions were justifed or were in fact blind spots. It concludes with some reflections on what our own blind spots may be, and whether we can see around them
