The Varieties of Religious Experience is a work by William James (1902).

Core claims

James did not defend religion against science; he weaponized empiricism against its own reductionist tendencies, demonstrating that the effects of religious experience are measurable even when their causes are not, thereby creating the epistemological space in which all depth psychology would subsequently operate.
The four marks of mystical experience James identified—ineffability, noetic quality, transiency, and passivity—function not as a taxonomy of the sacred but as a diagnostic protocol for distinguishing genuine psychic transformation from its imitations, a protocol that Jung, Otto, and the entire transpersonal tradition inherited without always acknowledging.
James’s radical empiricism is the philosophical precondition for Alcoholics Anonymous: Bill Wilson’s “white light experience” could be taken seriously as psychologically transformative precisely because James had already established that subjective experience carries its own evidential weight independent of theological or neurological explanation.

How does James’s insistence that mystical states carry “noetic quality” compare to Jung’s concept of the numinous as developed in his later writings, and does Hillman’s reversal in Re-Visioning Psychology—treating psychology as “a variety of religious experience”—complete or distort James’s original project?
In what ways does James’s framework of radical empiricism in The Varieties of Religious Experience provide the epistemological foundation for the “vital spiritual experience” that Jung prescribed to Rowland Hazard, as traced in Cody Peterson’s account of the formation of Alcoholics Anonymous?
Tarnas in Cosmos and Psyche reads James’s account of the reconciliation of opposites as an expression of the mysterium coniunctionis—how does this compare to Jung’s alchemical elaboration of the same principle, and does James’s phenomenological restraint offer a corrective to Jung’s mythological amplification?
