In our life as a civilized person in the industrial age, we are invaded by objects; how could an object have a "force" when it no longer has individuality?
Written language must be considered as a particular psychic reality. The book is permanent; it is an object in your field of vision. It speaks to you with a monotonous authority which even its author would not have. You are fairly obliged to read what is written.
If there is some end of the things we do . . . will not the knowledge of it, then, have a great influence on life? Shall we not, like archers who have a mark to aim at, be more likely to hit upon what we should? If so, we must try, in outline at least, to determine what it is, and of which of the sciences or capacities it is the object.
