But we have to note that such value-standards are only presumptive. Their status depends, on one hand, upon the extent in which the present situation is like the past. In a progressive or rapidly altering social life, the presumption of identical present value is weakened. And while it would be foolish not to avail one's self of the assistance in present valuations of the valuables established in other situations, we have to remember that habit operates to make us overlook differences and presume identity where it does not exist--to the misleading of judgment. On the other hand, the contributory worth of past determinations of value is dependent upon the extent in which _they_ were critically made; especially upon the extent in which the consequences brought about through acting upon them have been carefully noted. In other words, the presumptive force of a past value in present judgment depends upon the pains taken with its verification. In any case, so far as judgment takes place (instead of the reminiscence of a prior good operating as a direct stimulus to present action) all valuation is in some degree a revaluation. Nietzsche would probably not have made so much of a sensation, but he would have been within the limits of wisdom, if he had confined himself to the assertion that all judgment, in the degree in which it is critically intelligent, is a transvaluation of prior values. I cannot escape recognition that any allusion to modification or transformation of an object through judgment arouses partisan suspicion and hostility. To many it appears to be a survival of an idealistic epistemology. But I see only three alternatives. Either there are no practical judgments--as judgments they are wholly illusory; or the future is bound to be but a repetition of the past or a reproduction of something eternally existent in some transcendent realm (which is the same thing logically),[89] or the object of a practical judgment is some change, some alteration, to be brought about in the given, the nature of the change depending upon the judgment and yet constituting its subject-matter. Unless the epistemological realist accepts one of the two first alternatives, he seems bound, in accepting the third, to admit not merely that practical judgments make a difference in things as an after-effect (this he seems ready enough to admit), but that the import and validity of judgments is a matter of the difference thus made. One may, of course, hold that this is just what marks the distinction of the practical judgment from the scientific judgment. But one who admits this fact as respects a practical judgment can no longer claim that it is fatal to the very idea of judgment to suppose that its proper object is some difference to be brought about in things, and that the truth of the judgment is constituted by the differences in consequences actually made. And a logical realist who takes seriously the notion that moral good is a fulfilment of an
