Abstract
The central assumption behind James’s project, which is noted in many of the essays, is that religious knowledge is not possible. This assumption shapes the approach James takes, and limits the possible conclusions he can reach. It was an assumption shared by William Clifford, who is the chief target of James’s The Will to Believe. However, James goes in a different direction than Clifford. James agrees that religious knowledge is not possible, and yet asserts that religious experiences are useful. His hypothesis is that while religious experience does not provide knowledge, it can be the cause of beneficial effects in a person’s life. His focus on results or effects is an important part of his pragmatism, and seems to grow out of his assumption that religious knowledge is not possible. It is the combination of making religious experience an object of scientific inquiry and a pragmatic assessment of religious experience that makes James unique during his time.
