 Essentialists and others often rely on the alleged uniformity of claims of mystics around the world. In William James’s words, there is an alleged “eternal unanimity” among mystics (James 1958, 321). But as he also realized, “if we take the larger mass as seriously as religious mysticism has historically taken itself, we find that the supposed unanimity largely disappears” (James 1958, 325). Constructivists in particular emphasize the diversity of mystical experiences, indeed for them each mystical experience is utterly unique.
