This paper explicates and defends some of William James' more controversial claims in ‘The Will to Believe’. After showing some of the weaknesses in standard interpretations of James' position, I turn to James' Principles of Psychology and The Varieties of Religious Experience to spell out in more detail James' account of the nature of the attitudes of belief, doubt, and disbelief and link them to an account of the subject. In so doing, the moral force of the argument comes to (...) the fore by casting the question ‘Can we believe at will?’ in a new light. Through a discussion of the conversion experiences of The Varieties of Religious Experience and the kinds of self-transformations in which beliefs that once appeared dead become live that appear throughout James' psychology, the moral urgency of James' position in ‘The Will to Believe’ is clarified.
