William James (1842–1910) was an American philosopher and psychologist, widely regarded as the father of American psychology and one of the most influential thinkers of the nineteenth and early twentieth centuries. A founding figure of pragmatism, James taught at Harvard for decades, where his work shaped philosophy, psychology, and the study of religion in ways that continue to reverberate.
James’s contributions span an extraordinary range. His landmark Principles of Psychology (1890) established psychology as a rigorous empirical discipline. His philosophical writings—including The Will to Believe, Pragmatism, and A Pluralistic Universe—developed a vision of truth as something made rather than merely found, tested in lived experience and practical consequence. In The Varieties of Religious Experience (1902), he brought the same empirical seriousness to mysticism, conversion, and faith, treating religious experience as genuine data about human consciousness and its possibilities.
What animates James’s legacy, and gives it enduring resonance, is his insistence that ideas must be tested against the full weight of human life—its dangers, its moral demands, its capacity for transformation. His account of the “strenuous mood”—the awakening of our deepest energies in response to genuine stakes and infinite demands—captures something essential about the relationship between faith and moral agency. For James, a world without God risks collapsing into a “don’t-care” temperament; religious faith, by opening an infinite scale of obligation and possibility, frees “every sort of energy and endurance, of courage and capacity for handling life’s evils.” This is not theology as mere comfort but as a spur to transformation. His vision of cooperative moral adventure—a world whose perfection is “conditional merely” on whether each agent does their “level best”—frames human existence as a genuinely open, participatory project, one where trust, risk, and collaborative effort are constitutive of whatever good is achieved. That vision sits naturally alongside Mormon transhumanist convictions about theosis, participatory atonement, and humanity’s co-creative role in its own divine future.
