Do the same epistemic standards govern scientific and religious belief? Or should science and religion operate in completely independent epistemic spheres? Commentators have recently been divided on William James’s answer to this question. One side depicts “The Will to Believe” as offering a separate-spheres defense of religious belief in the manner of Galileo. The other contends that “The Will to Believe” seeks to loosen the usual epistemic standards so that religious and scientific beliefs can both be justified by a unitary (...) set of evidentiary rules. I argue that James did build a unitary epistemology but not by loosening cognitive standards. In his psychological research, he had adopted the Comtian view that hypotheses and regulative assumptions play a crucial role in the context of discovery even though they must be provisionally adopted before they can be supported by evidence. “The Will to Believe” relies on this methodological point to achieve a therapeutic goal—to convince despairing Victorians that religious faith can be reconciled with a scientific epistemology. James argues that the prospective theist is in the same epistemic situation with respect to the “religious hypothesis” as the scientist working in the context of discovery. (shrink)

This article investigates the history of the relation between idealism and pragmatism by examining the importance of the French idealist Charles Renouvier for the development of William James's ‘Will to Believe’. By focusing on French idealism, we obtain a broader understanding of the kinds of idealism on offer in the nineteenth century. First, I show that Renouvier's unique methodological idealism led to distinctively pragmatist doctrines and that his theory of certitude and its connection to freedom is worthy of reconsideration. Second, (...) I argue that the technical vocabulary and main structure of the argument from the ‘Will to Believe’ depend upon Renouvier's idealist theory of knowledge and psychology of belief, and that taking account of this line of influence is of crucial importance for establishing the correct interpretation of James's work.

Renouvier criticized Comte’s positivist philosophy of science and proposed a social contract approach for dealing with normative questions in philosophy of science as well as moral philosophy. Renouvier then questioned Kant’s distinction between practical and theoretical reason and argued that judgments concerning epistemic warrant must be freely made in the same way that moral judgments are made. What counts as scientific knowledge depends on a consensus within the scientific community that develops over time through critical inquiry in much the same (...) way that a legitimate contract governing society at large must. But a scientific contract consisting of conventionally held theories and methods depends for its justification on a larger social contract that guarantees freedom of inquiry. (shrink)
