are properly not objects of knowledge at all. Our conceptions always require a sense-content to work with, and as the words 'soul,' 'God,' 'immortality,' cover no distinctive sense-content whatever, it follows that theoretically speaking they are words devoid of any significance. Yet strangely enough they have a definite meaning for our practice. We can act as if there were a God; feel as if we were free; consider Nature as if she were full of special designs; lay plans as if we were to be immortal; and we find then that these words do make a genuine difference in our moral life. Our faith that these unintelligible objects actually exist proves thus to be a full equivalent in praktischer Hinsicht, as Kant calls it, or from the point of view of our action, for a knowledge of what they might be, in case we were permitted positively to conceive them. So we have the strange phenomenon, as Kant assures us, of a mind believing with all its strength in the real presence of a set of things of no one of which it can form any notion whatsoever.
My object in thus recalling Kant's doctrine to your mind is not to express any opinion as to the accuracy of this particularly uncouth part of his philosophy, but only to illustrate the characteristic of human nature which we are considering, by an example so classical in its exaggeration. The sentiment of reality can indeed attach itself so strongly to our object of belief that our whole life is polarized through and through, so to speak, by its sense of the existence of the thing believed in, and yet that thing, for purpose of definite description, can hardly be said to be present to our mind at all. It is as if a bar of iron, without touch or sight, with no representative faculty whatever, might nevertheless be strongly endowed with an inner capacity for magnetic feeling; and as if, through the various arousals of its magnetism by magnets coming
