James Henry Leuba,
The Psychological Origin and the Nature of Religion…
(1909)
“ We think because we will. Thought does not exist for itself; it is the instrument of desire. To discover ways and means of gratifying proximate or distant desires, needs, cravings, is the function of intelligence. The psychologist speaks, therefore, of the instrumental character of thought, and considers cognition to be a function of conduct. The mastery of desire over thought is abundantly illustrated in the history of belief, and nowhere so strikingly as in Religion. ”
