This brings me to the consideration of another theory in which the concept of utility plays a large, indeed a predominant part. This is the theory of the relation of knowledge to life that is given to us in the philosophy of Bergson. I have in one of the volumes of this series given an account of this philosophy; I am here only dealing with its relation to this special problem of the nature of truth. It has been claimed that this philosophy is only a form of pragmatism, but it is not a theory of truth, and it has this essential difference from pragmatism that it is the intellect and not truth that is a utility. Before we consider the question that it gives {64} rise to in regard to truth, let us first examine the theory of the intellect, and the nature of its utility. The intellect is a mode of activity, an endowment acquired in the course of evolution, and which has been retained and perfected because of its utility. This does not mean that the intellect directs us to what is useful and inhibits us from courses fatal to life, neither does it mean that it gives us any power to make true what is not already true, it means that the power to acquire knowledge is useful. There is a contrast in our own existence between our life and our intellect. To understand the way in which the intellect serves the living creature endowed with it, we need only regard it from the standpoint of ordinary experience. We know in ourselves that our life is wider than our intellect, and that our intellect serves the activity of our life. The common expressions we employ, such as using our wits, taking an intelligent interest, trying to think, all imply a utility distinct from the intellect. So viewed, our life appears as an active principle within us, maintaining our organism in its relations, active and passive, and reactive to the reality outside and independent of it. Our intellect also seems both active and passive. It receives the influences that stream in upon us from the reality around us, it apprehends and interprets them, and works out the lines of our possible action in regard to them. The influences that flow in upon us from the outside world are already selected before our intellect apprehends them, for they flow in by the avenues of our senses, and the senses are natural instruments of selection. If we picture these influences as vibrations, then we may say that a certain group of vibrations of a very rapid frequency are selected by the eye and give rise to vision, that another group of very much lower frequency are selected by the ear and {65} give the sensation of sound, and other groups are selected by taste, smell, and touch. Many groups are known indirectly by means of artificial instruments, and all the infinite series that unite these groups of the actually experienced vibrations escape our apprehension altogether--we have no means of selecting them. But all these sense
