Pragmatism

...a quarter of a century ago I was led to the doctrine and maxim of right thinking that, if we search out all the practical consequences of a conception, we have in their aggregate the entire meaning of that conception. This doctrine, known as pragmatism, has certainly found some redoubtable defenders. Of the immediate utility of the maxim in the study of philosophy, nobody who has had experience in such use of it is ever likely to speak lightly. I believe, too, that it suggests a conception of the nature of intellect, and a theory of the relation of thought to the body, from which psychologists have still something to learn.
