Excerpt from Lectures on the Experimental Psychology of the Thought-Processes In a course of lectures on the elementary psychology of Feeling and Attention, published last year, I remarked that "the system of psychology rests upon a threefold foundation: the doctrine of sensation and image, the elementary doctrine of feeling, and the doctrine of attention." This statement, which formed the basis of my whole discussion, was promptly challenged by reviewers. I was misled, they affirmed, by a sensationalistic bias; I should have taken account of current experimental work upon the thought-processes; I had no right to assume that all intellection is imaginal in character. I could not but acknowledge the essential justice of this criticism, although I could not either accept my critics' point of view. I was, indeed, engaged in writing a brief defence of psychological sensationalism, when I received an invitation to deliver a series of lectures at the University of Illinois. Here was an opportunity, of which I gladly availed myself, to treat in some little detail of the recent experimental contributions to the psychology of thought. The present volume is the result.
