The Positive Outcome of Philosophy. Joseph Dietzgen 1887

XIII The Extent to Which the Doubts of the Possibility of Clear and Accurate Understanding Have Been Overcome

A contemporaneous professor of philosophy, Kuno Fischer, of Jena, says: “The problem of modern philosophy is the understanding of things.” But this problem does not occupy modern philosophy alone; it was also considered by ancient philosophy. Even more, it belongs to the whole world. All the world, I mean the whole human world, and especially the sciences, search after understanding. I do not say this for the purpose of setting the Professor right, for I acknowledge that he is a fairly deserving philosopher. If I cared to go through his works, I should surely find other passages which state the problem of philosophy more accurately and concretely, to the effect that philosophy does not strive merely for the indefinite “understanding of things,” but rather for the special understanding of that particular thing which bears the name of “understanding.” Philosophy at the climax of its development seeks to understand “understanding.” It has seriously attempted the solution of this problem so long as men think, so far as our historical records go.

After that which we have already said about the beginning and the end of things and about their immortality, it will be easily understood that the thing called understanding has no more historical beginning than all the rest. The known grows out of the unknown, the conscious out of the unconscious. Our modern consciousness, though agreeably cultivated, is still an undeveloped, unconscious consciousness. Nevertheless, development has gone far enough to make it plain that understanding is anti-religious. Especially the understanding of understanding, the outcome of positive philosophy, has a pronounced anti-religious, and to that extent “destructive,” tendency. But one should not have an exaggerated idea of this destruction. Here, under this sun, nothing is destroyed without leaving the basis for the growth of new life from the ruins. It belongs to the conception of the universe to understand that it is the main conception required for the conception of conception, for the understanding of understanding.

The history of philosophy begins with the decay of heathen religion, and the history of modern philosophy with the decay of Christian religion. Since religion must be preserved for the people according to the official declarations of the rulers, the official professors are not clear and accurate expounders of the positive outcome of philosophy. No matter how great the work of Spinoza, Leibniz, Kant, and Hegel may be, yet the followers of Kant and Hegel have no freedom of research, and Kuno Fischer, although very close to the root of the subject, is nevertheless doomed to remain in the mystification of the function of conceiving and of understanding. His profession clouds his judgment.

“Nature,” says this professor, “is regarded as the first object of understanding, as the principle from which everything else follows. In this respect modern philosophy is naturalistic. It is taken for granted that nature can be understood, or that the possibility of understanding things is given. Modern philosophy makes this assumption dogmatically.... The Kantian philosophy, on the other hand, assumes a critical, not a dogmatic, attitude toward the possibility of understanding.” (System of Logic and Metaphysics, by Kuno Fischer, second edition, pages 104 and 109.) In this latter, critical, stage, the subject is kept rather hot by the professors of philosophy. The critics are still engaged in exclaiming: Be amazed, oh world! How is understanding possible?

In the first place, there is nothing to be amazed at. Why is not the “naturalistic” philosopher consistent by recognizing his special object, understanding, as a natural object?

The “supposition” that an understanding of things is possible, is neither a supposition nor anything “dogmatic.”

The philosophers should abandon their old hobby of trying to prove anything by syllogisms. Nowadays, a case is not substantiated by words, but by facts, by deeds. The sciences are sufficiently equipped, and thus the “possibility of understanding” is demonstrated beyond a doubt.

“But,” say the critics who are so wise that they hear the grass growing, “are those perceptions which are produced by the exact sciences really perceptions? Are they not simply substitutes? Those sciences recognize only the phenomena of things; but where is the understanding which perceives the truth?”

We shall offer it to them. You are naturalists. Well, then, nature is the truth. Or are you spiritualists who make a metaphysical distinction between the truth and the phenomenon? To understand means to distinguish and judge. The semblance must be distinguished from the truth, but not in an excessive manner. It must be remembered that even the most evil semblance is a natural phenomenon, and the sublimest truth is only revealed by phenomena, just because it is natural.

But the old logic cannot stand any contradictions. Semblance and truth are contradictions for it and they cannot be reconciled by it. But the irreconcilable simply consists in entertaining, in this monistic world, thoughts which are supposed to be totally different. Hence old style logic lacks entirely the mediating manner of thought which does not elevate understanding and its faculty of thought to the skies, but is satisfied to regard it as a very valuable, but still natural, quality.

The old logic could not construct any valid rules of thought, because it thought too transcendentally of thinking itself. It was not satisfied that thought is only a faculty, a mode of doing, a part of true nature, but the nature of truth was spiritualized by it into a transcendental being. Instead of grasping the conception of spirit with blood and flesh, it tries to dissolve blood and flesh into ideas. That would be well enough, if such a solution of the riddles were meant to have no other significance than that of symbols.

The old logic contains long chapters about the proofs of truth. It is supposed to be “identical” with the idea and to be proven by ideas. This would be all right, if we remained conscious of the secondary relation in which the idea and understanding stand to truth. But old line logic is not conscious of this relation. On the contrary. Its consciousness distorts that relation. It elevates the mind to the first place and relegates blood and flesh to the last.

“The necessity of a conception is proven by the impossibility of its opposite. An idea is contradicted by proving its impossibility. This impossibility is demonstrated when it can be proven that a thing is at the same time A and not-A, or when it can be shown that a thing is neither A nor not-A. The first mode of proof is called antinomy, the second, dilemma.”

In this representation of the logical proof much is said of the “thing,” for instance this: A thing cannot be at the same time straight and crooked, true and untrue, light and dark. The excellence of this doctrine is easily apparent, because it is overlooked that the concept “thing” is not a fixed, but a variable one. If a straight line is a thing, and a crooked line another thing, and if these two things are held to be opposed to one another, then the above logic is the most justified in the world. But who claims that there are not many straight lines which are crooked at one end, which run straight on for a certain distance and then turn? Who will define to us what a line is? A line may be composed of 10, 20, 30, etc., parts, and each part is a line.

Before anything to the point can be said about the logical laws, it is necessary to say above all how it stands with the relation of the whole to its parts, of the universe to its subdivisions. The old theological question of God and his creatures, the old metaphysical question of the unity and the multiplicity, of truth and its phenomena, reason and consequence, etc., in one word, the question of metaphysical categories must be solved and settled before the definition of the minor factors of understanding, the questions of formal logic, can be attempted.

What is a “thing?” A clergyman would answer: Only God is something, everything else is nothing! And we say: Only the universe is something, and everything in it consists of vacillating, changing, precarious, varicolored, fluid, variable phenomena or relativities.

In our times, up to which the theologians have speculated so much and contributed so little to understanding, one can hardly touch on the God concept without annoying the reader. Yet it is very essential for a thorough understanding of the human mind to point out that the God concept and the universe concept are analogous concepts. Not in vain have the first minds of modern philosophy, such as Cartesius, Spinoza, Leibniz, occupied themselves so closely with the God concept. They invented the so-called ontological proof of the existence of God. This proof if applied to the universe, testifies to its divinity. A metaphysical cloud pusher as well as the physical cosmos are fundamentally concepts of the most perfect being. It makes little difference whether we say that the concept of the universe, or of the cosmos, or of the most perfect being is innate in man. If this concept were not existing, it would lack the main thing required for its perfection. Hence the most perfect being must exist. And it does. It is the universe, and everything belongs to its existence. Nothing is excluded from it, least of all understanding. The latter is, therefore, not only possible, but a fact, which is proven by the very concept of the most perfect being.

This ought to be sufficient to help us over the doubts of the critics, especially over Kantian criticism, or rather dualism. Kant did not care to accept the dogma of the possibility of understanding without examination; he wished to investigate first. He then discovered that we may understand correctly, provided we remain with our understanding on the field of common experience; in other words, in the physical universe, and refrain from digressing into the metaphysical heaven. But he did not understand that the metaphysical heaven against which he warns us would be an obsolete standpoint in our days.

He still permits that transcendental possibility to remain and while he warns us not to stray into it with our understanding he omits to tell us to also keep away from it with our intuition. Kant struggles about between the “thing as phenomenon” and the “thing itself.” The former is material and may be understood, the latter is supernatural and may be believed or divined. With this doctrine, he again made understanding, the object of modern philosophy, problematical, thus inviting us to investigate further.

This we have done, and it is now the positive outcome of philosophy to know clearly and definitely and understand that understanding is not only a part of this world of phenomena, but a true part of the general truth, beside which there is no other truth, and which is the most perfect being.

Philosophy took its departure from confused wrangling about that which is and that which is not, especially from the religious disappointments met by the Greek nation when its world of deities dissolved into phantasms. Humanity demands a positive, strong, unequivocal, reliable understanding. Now, in this world of ours, the solid is so mixed with the fluid, the imperishable with the perishable, that a total separation is impossible. Nevertheless our intellect catches itself continually making separations and distinctions. Should not that appear mysterious to it? The necessary and natural result was the problem of the theory of understanding, the special question of philosophy: Which is the way to an indubitably clear and positive understanding?

The summit of Grecian philosophy bears the name of Aristotle. He was a practical man who did not like to stray into the distance when he could find good things near by, and he did not concern himself about the descent of understanding. Its platonic origin from an ideal world went instinctively against his grain. He, therefore, took hold of the question at the nearest end and analyzed the positive knowledge available at that time. But since Grecian science and the knowledge of Aristotlean times were rather slim, his attempt to demonstrate logic did not produce any decisive results. But it had been discovered that it was possible to make positive deductions from fixed premises.

Aristotle clung to this. He showed clearly and definitely, excellently and substantially, how logical deductions should be made in order to arrive at positive understanding. All dogs are watchful. My pug-dog is a dog, therefore it is watchful. What can be more evident? Why, then, speculate about God, freedom, and immortality, when indubitable knowledge may be obtained by the formal method of exact deductions?

But Aristotle had overlooked something, or, being a practical man, perhaps overlooked it intentionally. The premise from which he deducted the watchfulness of dogs in general, was handed down by tradition and had been accepted on faith. But was it founded on fact? Could there not be some dogs who lacked the quality of watchfulness, and might not our pug-dog be very unreliable, in spite of all exact deductions? In the case of the pug-dog this would not be of very great moment. But what about the question of the beginning and end of the world, or the question of the existence of God? The Grecian gods had been outgrown by Aristotle.

The history of logic, and of philosophy in general, is interrupted by Christianity and by the decline of the antique world, until the reformation opens a new era. The Catholic church had, in its own way, thoroughly settled the great questions of the true nature of things, of beginning and end, reason and consequence. But when it, and with it Christianity, began to disintegrate, disbelief once more posed in the brains of the philosophers the old question: How do we obtain reliable and true understanding? Reliability and truth were at that time still identical.

Bacon and Descartes are the men who started the investigation. Both of them were disgusted with Aristotle and with his formal logic, particularly with the subtleties of scholasticism. It did not satisfy this new epoch to found positive understanding on traditional contentions and exact deductions therefrom. It is a radical epoch and, therefore, epoch-making. The new philosophers have the aim of unequivocal understanding in common with the ancient philosophers. Bacon still connects himself with the stock in trade of the past. His historian says of him that one should not reiterate that Bacon took his departure from experience, for this means nothing or nothing more than that Columbus was a mariner while the main thing is that he discovered America.... He wanted to find a new logic corresponding to the new life.... The inventive human mind has created the new time, the compass, the powder, the art of typography.... He wanted a new logic which corresponded to the spirit of invention. He, the philosopher of invention, was Lord Chancellor of England, was a man of the world. Not only himself, but also his science, was too ambitious, too full of energy, too world-embracing, for him to bury himself in solitude. That is a glory for a philosopher, but at the same time an obstacle for his special task, for the new logic. He recognized the import of his task only in its general outlines. But his contemporary and successor Descartes approached the matter more radically and pointedly.

Although in recent times the human mind had demonstrated its positive faculty of understanding in natural sciences, especially by inventions, still it was prejudiced by religious improbabilities in its great premises dealing with the essence of things and men, with the “good, true, and beautiful,” as the ancients called it. In order to end his doubts, Descartes elevates radical doubt to the position of a principle and of a starting point for all understanding. Then he cannot doubt that he is at least searching for truth. He who does not believe in any understanding, any science, any inventions, cannot doubt at all events that the impulse for understanding is there. It, at least, is undeniable. Cogito, ergo sum – I think, therefore I am – that is a premise which cannot be shaken. The rest, thinks Descartes, may be deducted by Aristotlean methods.

With this thought, the philosopher of modern times relapsed into the old error that anything positively true could be ascertained with logical formulas. His consciousness of the thoughts stirring in his brain, I might say his flesh and blood, convinced him by matter-of-fact evidence of the reality of their existence.

This fact had hitherto been misunderstood. It is claimed that Descartes could convince himself only of the existence of his soul, of his thought, by evidence. No, my feeling, my sight, my hearing, etc., are just as evident to me as my thinking, and simultaneously with sight and hearing that which is heard and seen. The separation of subject and object can and must be merely a formality.

The Descartian thesis has been distorted into the statement that nothing is evident to man but his own subjective conception. And the ideology has been carried to the extreme of calling the whole world an idea, a phantasmagoria. True, Descartes needed God in order to be sure that his conceptions did not cheat him.

In order to prove that we no longer need such extravagant means in our times, I shall devote another chapter to this subject.
