And, besides this commonplace, there is only left for him to mean two one-sided and doubtful assertions to the effect that certain properties belong to none but true ideas. There is the assertion that all ideas which pay in the long run are true, and the assertion that all ideas which pay for some considerable time are true. And as to the first, it _may_ be true; but it may also be doubted, and Professor James gives us no reason at all for thinking that it is true. Assuming that religious ideas have been useful in the past, is it quite certain that they may not permanently continue to be useful, even though they are false? That, in short, even though they are not true, they nevertheless will be useful, not only for a time, but in the long run? And as for the assertion that all ideas, which pay for a considerable time, are true, this is obviously more doubtful still. Whether certain religious ideas will or will not be useful in the long run, it seems difficult to doubt that many of them have been useful for a considerable time. And why should we be told dogmatically that all of these are true? This, it seems to me, is by far the most interesting assertion, which is left for Professor James to make, when we have rejected the theory that the property of being useful belongs to _all_ true ideas, as well as to none but true ones. But he has given no reason for asserting it. He seems, in fact, to base it merely upon the general untenable theory, that utility belongs to _all_ true ideas, and to none but true ones; that this is what truth means. These, then, seem to me the plainest and most obvious objections to what Professor James says about the connection between truth and utility. And there are only two further points, in what he says under this head, that I wish to notice.
