Abstract
The question of a pragmatist justification of religious beliefs appeared in James’s writing in 1898, as an alternative to Royce’s theory of the absolute. This pragmatist justification was repeated in The Varieties of Religious Experiences in 1902 but it failed to give a proper account of the truth of religious beliefs based on private religious experiences and ultimately failed to answer Royce’s arguments. James knows that any possible pragmatist justification of religious belief based on the practical consequences of religious belief must be completed by a metaphysical theory of the non-natural causality of religious experiences. But that would require going beyond the dualistic and naturalistic account of the Varieties. Nevertheless, the difficulties of the monistic theories of the Essays in Radical Empiricism pushed James to defend, in A Pluralistic Universe, a pantheistic theory in which the Absolute is accepted as a logical possibility, which in turn supposes to accept the composition theory of consciousness that he had rejected in The Principle of Psychology. Therefore, James’s final theory isn’t very different to Royce’s theory, since Royce’s theory is not a theory of the necessity of the Absolute but rather a theory of its possibility.
