And, I repeat, each of these answers, although they logically quite exclude each other, has the right to claim the title of _truth_; for if it has not power enough to make the other answers bow down before it, at all events it has the necessary strength to repel its opponents' attacks and to defend its sovereign rights. Instead of a sole and omnipotent truth before which the weak and helpless errors tremble, you have before you a whole line of perfectly independent truths excellently armed and defended. Instead of absolutism, you have a feudal system. And the vassals are so firmly ensconced in their castles that an experienced eye can see at once that they are impregnable. I took for my instance Schopenhauer's doctrine of the value of life. But many philosophic doctrines, although they issue from the premiss of one sovereign truth, display examples of the plurality of truths. It is usually believed that one should study the history of philosophy in order to be palpably convinced that mankind has gradually mastered its delusions and is now on the high road to ultimate truth. My opinion is that the history of philosophy must bring every impartial person, who is not infected by modern prejudices, to a directly opposite conclusion. There can be no doubt that a whole series of questions exists, like that of the value of life, which by their very essence do not admit of a uniform solution. To this testimony is often borne by men whose very last concern is to curtail the royal prerogative of sovereign truth: Natorp confidently asserts that Aristotle not only did not understand but could not understand Plato. 'Der tiefere Grund ist die ewige Unfähigkeit des Dogmatismus sich in der Gesichtspunkt der kritischen Philosophie überhaupt zu versetzen.' 'Eternal incapability' --what words! And used not of any common-place person, but of the greatest human genius known to us, of Aristotle. Had Natorp been a little more inquisitive, 'eternal incapability' of that kind should have worried him at least as much as Plato's philosophy, on which he wrote a large book. For here is evidently a great riddle. Different people, according to the different constitution of their souls, are while yet in their mother's womb destined to have different philosophies. It reminds me of the famous Calvinistic view of predetermination. Just as from before birth God has destined some to damnation, others to salvation; so to some it is given and from others withheld, to know the truth.
