Although James does not here explain the way in which the truth or evidence regarding religious belief depends upon our first having religious belief, he does argue that it is a part of the religious belief itself that its own truth or the evidence of its own truth depends upon our first believing it. In the preface to the published version of "The Will to Believe" James offers a different argument for the way in which the evidence for religion depends upon our belief. There he contends that it is through the failure or thriving of communities of religious believers that we come to have evidence of the truth of their religious beliefs. In this way, to acquire evidence for religious belief, we must first have believers who adopt such belief without sufficient evidence. Much later in life, in his "Pragmatism: A New Name for Some Old Ways of Thinking" lectures, James also mentions the possibility that God's existence may actually depend upon our belief in his existence.
