And there is only one other point, in what Professor James says in connection with the "instrumental" view of truth, upon which I wish to remark. We have seen that he seems sometimes to hold that beliefs are true, _so long as_ they are "profitable to our lives." And this implies, as we have seen, the doubtful proposition than any belief which is useful for some length of time, is true. But this is not all that it implies. It also implies that beliefs are true _only_ so long as they are profitable. Nor does Professor James appear to mean by this that they _occur_, only so long as they are profitable. He seems to hold, on the contrary, that beliefs, which are profitable for some time, do sometimes finally occur at a time when they are not profitable. He implies, therefore, that a belief, which occurs at several different times, may be true at some of the times at which it occurs, and yet untrue at others. I think there is no doubt that this view is what he is sometimes thinking of. And this, we see, constitutes a quite new view as to the connection between truth and utility--a view quite different from any that we have hitherto considered. This view asserts not that every true idea is useful at some time, or in the long run, or for a considerable period; but that the truth of an idea may come and go, as its utility comes and goes. It admits that one and the same idea sometimes occurs at times when it is useful, and sometimes at times when it is not; but it maintains that this same idea is true, at those times when it is useful, and not true, at those when it is not. And the fact that Professor James seems to suggest this view, constitutes, I think, a second most serious objection to what he says about the connection of truth and utility. It seems so obvious that utility is a property which comes and goes--which belongs to a given idea at one time, and does not belong to it at another, that anyone who says that the true is the useful naturally seems not to be overlooking this obvious fact, but to be suggesting that truth is a property which comes and goes in the same way. It is, in this way I think, that the "instrumental" view of truth is connected with the view that truth is "mutable." Professor James does, I think, imply that truth is mutable in just this sense--namely, that one and the same idea may be true at some of the times at which it occurs, and not true at others, and this is the view which I have next to consider.
