The Greeks had no knowledge of the printing-press, and no literary reviews. They usually took their wisdom out into the market-place, and applied all their efforts to persuade people to acknowledge its value. And it is hard to maintain that wisdom, which is constantly being offered to people, should not adapt itself to people's tastes. It is truer to say that wisdom became accustomed to value itself to the exact degree to which it could count on people's appreciation. In other words, it appears that the value of wisdom, like that of all other commodities, not only with us, but with the Greeks before us, is a social affair. The most modern philosophy has given up concealing the fact. The teleology of the rationalists, who follow Fichte, as well as of the pragmatists who consider themselves the successors of Mill is openly based upon the social point of view, and speaks of collective creations. Truth which is not good for all, and always, in the home market and the foreign—is not truth. Perhaps its value is even defined by the quantity of labour spent upon it. Marx might triumph: under different flags his theory has found admission into every sphere of contemporary thought. There would hardly be found one philosopher who would apply the method of verifying truth which I have proposed; and hardly a single modern idea which would stand the test.

Doctrines and Deductions

If you want to ruin a new idea—try to give it the widest possible publicity. Men will begin to reflect upon it, to try it by their daily needs, to interpret it, to make deductions from it, in a word to squeeze it into their own prepared logical apparatus; or, more likely, they will cover it up with the débris of their own habitual and intelligible ideas, and it will become as dead as everything that is begotten by logic. Perhaps this explains the tendency of philosophers to so clothe their thoughts that their form may hinder the approach of the general public to them. The majority of philosophic systems are chaotically and obscurely expounded, so that not every educated person can understand them. It is a pity to kill one's own child, and every one does his best to save it from premature death. The most dangerous enemies of an idea are 'deductions' from it, as though they followed of themselves. The idea does not presuppose them; they are usually pressed upon it. Indeed, people very often say: 'The idea is quite right, but it leads to conclusions which are not at all acceptable.' Again, how often has a philosopher to attend the sad spectacle of his pupil's deserting all his ideas, and feeding only upon the conclusions from them. Every thinker who has had the misfortune to attract attention while he was yet alive, knows by bitter experience what 'deductions' are. And yet you will rarely find a philosopher to offer open and courageous resistance to his continuators; and still more rarely a philosopher to say outright that his work needs no continuation, that it will not bear continuation, that it exists only in and for itself, that it is self-sufficient. If some one said this, how would he be answered? People could not dispute with him—try to dispute with a man who wants neither to dispute nor to demonstrate.

The only answer is an appeal to the popular verdict, to lynch law. People are so weak and naïve that they will at all costs see a teacher (in the usual sense of the word) in every philosopher. In other words, they really want to throw upon him the responsibility for their actions, their present, their future, and their whole fate. Socrates was not executed for teaching, but because the Athenians thought he was dangerous to Athens. And in all ages men have approached truth with this criterion, as though they knew beforehand that truth must be of use and able to protect them. One of the greatest teachings, Christianity, was also persecuted because it seemed dangerous to the self-appointed guardians, or, if you will, because it was really very dangerous to Roman ideals. Of course, neither Socrates' death nor the deaths of thousands of the early Christians saved the ancient culture and polity from decay: but no one has learned anything from the lesson. People think that these were all accidental mistakes, against which no one was secure in ancient times, but which will never again recur; and therefore they continue to make 'deductions' as they used from every truth, and to judge the truth by the deductions they have made. And they have their reward. Although there have been on earth many wise men who knew much that is infinitely more valuable than all the treasures for which men are ready even to sacrifice their lives, still wisdom is to us a book with seven seals, a hidden hoard upon which we cannot lay our hands. Many—the vast majority—are even seriously convinced that philosophy is a most tedious and painful occupation to which are doomed some miserable wretches who enjoy the odious privilege of being called philosophers. I believe that even professors of philosophy, the more clever of them, not seldom share this opinion and suppose that therein lies the ultimate secret of their science, revealed to the initiate alone. Fortunately, the position is otherwise. It may be that mankind is destined never to change in this respect, and a thousand years hence men will care much more about 'deductions,' theoretical and practical, from the truth than about truth itself; but real philosophers, men who know what they want and at what they aim, will hardly be embarrassed by this. They will utter their truths as before, without in the least considering what conclusions will be drawn from them by the lovers of logic.

Truths, Proven and Unproven

Whence did we get the habit of requiring proofs of each idea that is expressed? If we put aside the consideration, as having no real meaning in the present case, that men do often purposely deceive their neighbours for gain or other interests, then strictly speaking the necessity for proof is entirely removed. It is true that we can still deceive ourselves and fall into involuntary error. Sometimes we take a vision for a reality, and we wish to guard against that offensive mistake. But as soon as the possibility of bona fide error is removed, then we may relate simply without arguments, judgments, or references. If you please, believe; if you don't, don't. And there is one province, the very province which has always attracted to itself the most remarkable representatives of the human race, where proofs in the general acceptation are even quite impossible. We have been hitherto taught that that which cannot be proved, should not be spoken about. Still worse, we have so arranged our language that, strictly speaking, everything we say is expressed in the form of a judgment, that is, in a form which presupposes not merely the possibility but the necessity of proofs. Perhaps this is the reason why metaphysics has been the object of incessant attack. Metaphysics evidently was not only unable to find a form of expression for her truths which would free her from the obligation of proof; she did not even want to. She considered herself the science par excellence, and therefore supposed that she had more largely and more strictly to prove the judgments which she took under her wing. She thought that if she were to neglect the duty of demonstration she would lose all her rights. And that, I imagine, was her fatal mistake. The correspondence of rights and duties is perhaps a cardinal truth (or a cardinal fiction) of the doctrine of law, but it has been introduced into the sphere of philosophy by a misunderstanding. Here, rather, the contrary principle is enthroned: rights are in inverse proportion to duties. And only there where all duties have ceased is the greatest and most sovereign right acquired—the right of communion with ultimate truths. Here we must not for one moment forget that ultimate truths have nothing in common with middle truths, the logical construction of which we have so diligently studied for the last two thousand years. The fundamental difference is that the ultimate truths are absolutely unintelligible. Unintelligible, I repeat, but not inaccessible. It is true that middle truths also are, strictly speaking, unintelligible. Who will assert that he understands light, heat, pain, pride, joy, degradation?

Nevertheless, our mind, in alliance with omnipotent habit, has, with the assistance of some strained interpretation, given to the combination of phenomena in the segment of universal life that is accessible to us, a certain kind of harmony and unity, and this from time immemorial has gained repute under the name of an intelligible explanation of the created world. But the known, which is the familiar, world is sufficiently unintelligible to make good faith require of us that we should accept unintelligibility as the fundamental predicate of being. It is impossible to hold, as some do, that the only reason why we do not understand the world is that something is hidden from us or that our mind is weak, so that if the Supreme Being wished to unveil the secret of creation to us, or if the human brain should so much develop in the next ten million years that he will excel us as far as we excel our official ancestor, the ape, then the world will be intelligible. No, no, no! By their very essence the operations which we perform upon reality to understand it are useful and necessary only so long as they do not pass a certain limit. It is possible to understand the arrangement of a locomotive. It is also legitimate to seek an explanation of an eclipse of the sun, or of an earthquake. But a moment comes—only we cannot define it exactly—when explanations lose all meaning and are good for nothing any more. It is as though we were led by a rope—the law of sufficient reason—to a certain place and left there: 'Now go wherever you like.' And since we have grown so used to the rope in our lives, we begin to believe that it is part of the very essence of the world. One of the most remarkable thinkers, Spinoza, thought that God himself was bound by necessity.

Let any one probe himself carefully, and he will find that he is not merely unable to think but almost unable to live without the hypothesis of Spinoza. The work of Hume, who so brilliantly disputed the axiom of causal necessity, was only half done. He clearly showed that it is impossible to prove the existence of necessary connection. But it is also impossible to prove the contrary. In the result, everything remained as before: Kant, and all mankind after him, has returned to Spinoza's position. Freedom has been driven into an intellectual world, an unknown land,

'from whose bourne
No traveller returns,'

and everything is in its former place. Philosophy wants to be a science at all costs. It is absolutely impossible for her to succeed in this; but the price she has paid for the right to be called a science, is not returned to her. She has waived the right of seeking that which she needed wherever she would, and she is deprived of the right for ever. But did she really need it? If you glance at contemporary German philosophy you will say without hesitation that it was not needed at all. Neither by mistake, nor even in pursuit of a new title, did she renounce her great vocation: it has become an intolerable burden to her. However hard it may be to confess, it is nevertheless indubitable that the great secrets of the universe cannot be manifested with the clarity and distinctness with which the visible and tangible world is opened to us. Not only others—you will not even convince yourself of your truth with the obviousness with which you can convince all men without exception of scientific truths.
