William James's 'The Will to Believe' Defended: Pragmatist Philosophy and the Right to Believe Without Evidence

publication · 2026-09-20

William James, a philosopher and psychologist active during the 19th and early 20th centuries, contended in his essay 'The Will to Believe' that it is justifiable to adopt beliefs in the absence of evidence if they enhance one’s life. He was born in 1842 and passed away in 1910, being the sibling of novelist Henry James Jr. Joining Harvard in 1872, he played a pivotal role in founding its psychology department. His personal battles with depression shaped his perspective on the will to address personal issues. In response to W.K. Clifford's evidentialism, he introduced prudential factors, using belief in God as a practical hypothesis. His pragmatism significantly impacted the self-help movement, prioritizing the individual effects of beliefs over institutional concerns.
