Lenin: Is there objective truth? Part four

Pieter Claesz, ‘Still Life with Musical Instruments’, 1623. The painting illustrates the senses through musical instruments, a compass, a book, food and drink, a mirror, incense and an open perfume bottle. The tortoise may be an illustration of touch or an allusion to the opposite (the tortoise isolating in its shell).

Acceptance or rejection of the concept matter is a question of the confidence man places in the evidence of his sense-organs, a question of the source of our knowledge, a question which has been asked and debated from the very inception of philosophy, which may be disguised in a thousand different garbs by professorial clowns, but which can no more become antiquated than the question whether the source of human knowledge is sight and touch, hearing and smell. To regard our sensations as images of the external world, to recognise objective truth, to hold the materialist theory of knowledge—these are all one and the same thing. To illustrate this, I shall only quote from Feuerbach and from two textbooks of philosophy, in order that the reader may judge how elementary this question is.

“How banal,” wrote Feuerbach, “to deny that sensation is the evangel, the gospel (Verkündung) of an objective saviour.” (Feuerbach, Sämtliche Werke, X. Band, 1866, S. 194-95) A strange, a preposterous terminology, as you see, but a perfectly clear philosophical line: sensation reveals objective truth to man. “My sensation is subjective, but its foundation or cause (Grund) is objective” (S. 195). Compare this with the quotation given above where Feuerbach says that materialism starts from the sensuous world as an ultimate (ausgemachte) objective truth.

Sensationalism, we read in Franck’s dictionary of philosophy, (Dictionnaire des sciences philosophiques [Dictionary of the Philosophical Sciences], Paris, 1875) is a doctrine which deduces all our ideas “from the experience of the senses, reducing knowledge to sensations”. There is subjective sensationalism (skepticism and Berkeleianism), moral sensationalism (Epicureanism),1 and objective sensationalism. “Objective sensationalism is materialism, for matter or bodies are, in the opinion of the materialists, the only objects that can affect our senses (atteindre nos sens).”

“If sensationalism,” says Schwegler in his history of philosophy, (Dr. Albert Schwegler, Geschichte der Philosophie im Umriss [History of Philosophy in Outline], 15-te Aufl., S. 194) “asserted that truth or being can be apprehended exclusively by means of the senses, one had only [Schwegler is speaking of philosophy at the end of the eighteenth century in France] to formulate this proposition objectively and one had the thesis of materialism: only the sensuous exists; there is no other being than material being.”

These elementary truths, which have managed to find their way even into the textbooks, have been forgotten by our Machists.

Note

1. Skepticism: a philosophical trend that casts doubt on the possibility of knowing objective reality. It arose in ancient Greece as early as the 4th to 3rd centuries B. C. It was founded by Pyrrho and Aenesidemus and Sextus Empiricus were among its prominent exponents. The adherents of ancient skepticism drew agnostic conclusions from the premises of sensationalism. Making the subjectivity of sensation into an absolute, the skeptics insisted on the need to refrain from any definite judgments about things. They considered that man cannot go beyond his sensations and determine their truth.

During the period of the Renaissance, the French philosophers Michel Montaigne, Pierre Charron and Pierre Bayle made use of skepticism for combating medieval scholasticism and the Church.

In the eighteenth century skepticism was revived in the agnosticism of Hume and Kant, and an attempt to modernise ancient skepticism was made by Gottlieb Schulze (Aenesidemus). The arguments of skepticism were used by the Machists, neo-Kantians and other idealist philosophical schools from the middle of the nineteenth to the beginning of the twentieth century.

Epicureanism: the doctrine of the ancient Greek materialist philosopher Epicurus of the 4th to 3rd centuries B. C. and his successors. The aim of philosophy, according to this doctrine, was man’s happiness, freeing him from suffering and enabling him to attain a state of bliss. It taught that philosophy was called upon to overcome obstacles to happiness: the fear of death due to ignorance of the laws of nature and giving rise therefore to belief in supernatural divine forces.

According to Epicurus, there are only atoms and the void in the universe, in which atoms move down under their own weight. Falling with the same velocity, the atoms swerve from their rectilinear movement, collide and concatenate, forming various bodies. Epicurus recognised the objective character of the properties of things and regarded the universe as infinite, governed by natural and not by divine laws. He denied the immortality and non-materiality of the soul, and maintained that it was a material body of fine parts distributed through the whole body structure. His theory of the material nature of the soul was closely  linked with his atheism, which negated gods’ interference in the affairs of nature and man.

As regards the theory of knowledge, Epicurus was a sensationalist. He supposed that very subtle images proceed from things and penetrate the human soul through the sense-organs. Conceptions of things are formed on the basis of the sense perceptions of the soul, in which memory preserves only the general features of images. Epicurus regarded sense-perceptions themselves as the criterion of truth, and he considered that the source of errors lay in the accidental character of individual sensations or in the overhasty formation of judgments. Epicurus gave a materialist, though rather naïve, interpretation of the fundamentals of the cognitive process.

The idealists, who distorted the teaching of this great materialist of ancient Greece, made more attacks on Epicureanism than on the other philosophical theories of antiquity.

In the definition of sensationalism quoted by Lenin, Franck rightly regards Epicureanism as a variety of it, but he draws an incorrect distinction between Epicureanism and objective materialist sensationalism. In his conspectus of the Lectures on the History of Philosophy by Hegel who did not understand Epicurus’ theory and distorted it, Lenin showed that Epicureanism was a form of ancient Greek materialism.

Lenin: Is there objective truth?

 

Bogdanov declares: “As I understand it, Marxism contains a denial of the unconditional objectivity of any truth whatsoever, the denial of all eternal truths” (Empirio-Monism, Bk. III, pp. iv-v). What is meant by “unconditional objectivity”? “Truth for all eternity” is “objective truth in the absolute meaning of the word,” says Bogdanov in the same passage, and agrees to recognise “objective truth only within the limits of a given epoch”.

Two questions are obviously confused here: 1) Is there such a thing as objective truth, that is, can human ideas have a content that does not depend on a subject, that does not depend either on a human being, or on humanity? 2) If so, can human ideas, which give expression to objective truth, express it all at one time, as a whole, unconditionally, absolutely, or only approximately, relatively? This second question is a question of the relation of absolute truth to relative truth.

Bogdanov replies to the second question clearly, explicitly and definitely by rejecting even the slightest admission of absolute truth and by accusing Engels of eclecticism for making such an admission. Of this discovery of eclecticism in Engels by A. Bogdanov we shall speak separately later on. For the present we shall confine ourselves to the first question, which Bogdanov, without saying so explicitly, likewise answers in the negative – for although it is possible to deny the element of relativity (Editor’s note: this should read ‘the element of the absolute’) in one or another human idea without denying the existence of objective truth, it is impossible to deny absolute truth without denying the existence of objective truth.

“…The criterion of objective truth,” writes Bogdanov a little further on (p. ix), “in Beltov’s sense, does not exist; truth is an ideological form, an organising form of human experience.”

Neither “Beltov’s sense” – for it is a question of one of the fundamental philosophical problems and not of Beltov – nor the criterion of truth – which must be treated separately, without confounding it with the question of whether objective truth exists – has anything to do with the case here. Bogdanov’s negative answer to the latter question is clear: if truth is only an ideological form, then there can be no truth independent of the subject, of humanity, for neither Bogdanov nor we know any other ideology but human ideology. And Bogdanov’s negative answer emerges still more clearly from the second half of his statement: if truth is a form of human experience, then there can be no truth independent of humanity; there can be no objective truth.

Bogdanov’s denial of objective truth is agnosticism and subjectivism. The absurdity of this denial is evident even from the single example of a scientific truth quoted above. Natural science leaves no room for doubt that its assertion that the earth existed prior to man is a truth. This is entirely compatible with the materialist theory of knowledge: the existence of the thing reflected independent of the reflector (the independence of the external world from the mind) is the fundamental tenet of materialism. The  assertion made by science that the earth existed prior to man is an objective truth. This proposition of natural science is incompatible with the philosophy of the Machists and with their doctrine of truth: if truth is an organising form of human experience, then the assertion that the earth exists outside any human experience cannot be true.

But that is not all. If truth is only an organising form of human experience, then the teachings, say, of Catholicism are also true. For there is not the slightest doubt that Catholicism is an “organising form of human experience.” Bogdanov himself senses the crying falsity of his theory and it is extremely interesting to watch how he attempts to extricate himself from the swamp into which he has fallen.

“The basis of objectivity,” we read in Book I of Empirio-Monism, “must lie in the sphere of collective experience. We term those data of experience objective which have the same vital meaning for us and for other people, those data upon which not only we construct our activities without contradiction, but upon which, we are convinced, other people must also base themselves in order to avoid contradiction. The objective character of the physical world consists in the fact that it exists not for me personally, but for everybody (that is not true! It exists independently of “everybody”!), and has a definite meaning for everybody, the same, I am convinced, as for me. The objectivity of the physical series is its universal significance” (p. 25, Bogdanov’s italics). “The objectivity of the physical bodies we encounter in our experience is in the last analysis established by the mutual verification and co-ordination of the utterances of various people. In general, the physical world is socially-co-ordinated, socially-harmonised, in a word, socially-organised experience” (p. 36, Bogdanov’s italics).

We shall not repeat that this is a fundamentally untrue, idealist definition, that the physical world exists independently of humanity and of human experience, that the physical world existed at a time when no “sociality” and no “organisation” of human experience was possible, and so forth. We shall dwell now on an exposure of the Machist philosophy from another aspect, namely, that objectivity is so defined that religious doctrines, which undoubtedly possess a “universal significance”, and so forth, come under the definition. But listen to Bogdanov again: “We remind the reader once more that ‘objective’ experience is by no means the same as ‘social’ experience…. Social experience is far from being altogether socially organised and always contains various contradictions, so that certain of its parts do not agree with others. Sprites and hobgoblins may exist in the sphere of social experience of a given people or of a given group of people – for example, the peasantry; but they need not therefore be included under socially-organised or objective experience, for they do not harmonise with the rest of collective experience and do not fit in with its organising forms, for example, with the chain of causality”.

Of course it is very gratifying that Bogdanov himself “does not include” social experience in regard to sprites and hobgoblins under objective experience. But this well-meant amendment in the spirit of anti-fideism by no means corrects the fundamental error of Bogdanov’s whole position. Bogdanov’s definition of objectivity and of the physical world completely falls to the ground, since the religious doctrine has “universal significance” to a greater degree than the scientific doctrine; the greater part of mankind cling to the former doctrine to this day. Catholicism has been “socially organised, harmonised and co-ordinated” by centuries of development; it “fits in” with the “chain of causality” in the most indisputable manner; for religions did not originate without cause, it is not by accident that they retain their hold over the masses under modern conditions, and it is quite “in the order of things” that professors of philosophy should adapt themselves to them. If this undoubtedly universally significant and undoubtedly highly-organised religious social experience does “not harmonise” with the “experience” of science, it is because there is a radical and fundamental difference between the two, which Bogdanov obliterated when he rejected objective truth. And however much Bogdanov tries to “correct” himself by saying that fideism, or clericalism, does not harmonise with science, the undeniable fact remains that Bogdanov’s denial of objective truth completely “harmonises” with fideism. Contemporary fideism does not at all reject science; all it rejects is the “exaggerated claims” of science, to wit, its claim to objective truth. If objective truth exists (as the materialists think), if natural science, reflecting the outer world in human “experience”, is alone capable of giving us objective truth, then all fideism is absolutely refuted. But if there is no objective truth, if truth (including scientific truth) is only an organising form of human experience, then this in itself is an admission of the fundamental premise of clericalism, the door is thrown open for it, and a place is cleared for the “organising forms” of religious experience.

Part one/to be continued…

On the importance of induction for knowledge

Ignaz Semmelweis, 1860

Ignaz Semmelweis worked as a doctor at the Vienna General Hospital between 1844 and 1848. He observed that a large proportion of the women in the First Maternity Division who were delivered of their babies contracted a serious and often fatal illness known as puerperal or childbed fever. In the adjacent Second Maternity Division of the same hospital, which accommodated almost as many women as the First, the death toll from childbed fever was much lower.

Semmelweis began his efforts to resolve the problem by considering various explanations that were current at the time; some of these he rejected as incompatible with well-established facts; others he subjected to specific tests.

One widely accepted view attributed puerperal fever to ‘epidemic influences’ spreading over districts. But Semmelweis questioned how such influences could have affected the First Division for years and not the Second. At the same time, there was hardly a case in the city of Vienna or in its surroundings. Semmelweis noted that women who had given birth in the street on their way to the hospital had a lower death rate than the average for the First Division.

Semmelweis noted that overcrowding could not have been the cause since it was a greater problem in the Second Division, partly because of the efforts of women to avoid the First Division. He also considered the diet and general care of the patients in the two Divisions and found there were no differences.

A commission found in 1846 that rough examination by the medical students was the cause, but Semmelweis rejected this view because the injuries resulting naturally from the birth process are much more extensive, and the examinations by the midwives in the Second Division, though done in much the same manner, didn’t have the same dangerous results. Even after the number of medical students was halved and their examinations of the women were reduced to a minimum, the mortality eventually rose to levels higher than before.

Psychological explanations were attempted (the visits of a priest to deliver the last sacraments to dying women was thought to have had a bad effect on the patients). Semmelweis tested this idea and found that the mortality in the First Division did not decrease. He altered the womens’ position of delivery for birth but again found no alteration in the mortality.

In 1847 a fatal accident suffered by a colleague – a cut on a finger from a scalpel used in an autopsy, resulting in the same symptoms he had observed in the victims of puerperal fever – gave Semmelweis the clue he needed. He realised that ‘cadaveric matter’, introduced by the scalpel, had caused the doctor’s illness and death. He realised that the doctors and students had been the carriers of the infection, moving directly to the wards after performing autopsies, having only superficially washed their hands.

Semmelweis again tested his idea by reasoning that if he were correct, his instruction that all medical students should wash their hands in a solution of chlorinated lime before making an examination, could prevent the fever. The mortality from the fever immediately began to decrease.

In further support of his hypothesis, Semmelweis noted that it accounted for the fact that the mortality in the Second Division was consistently so much lower: the midwives there did not engage in anatomical dissection. The hypothesis also explained the lower mortality among the ‘street births’: these women were rarely examined after admission. Again, the hypothesis accounted for the fact that the victims of the fever among the newborn babies were all among those whose mothers had contracted the disease during labor, when the infection could be transmitted to the baby before birth.

Semmelweis broadened his hypothesis by first sterilising his hands, then examining a woman suffering from cervical cancer, and then proceeding to examine a number of other women in the same room after only routine washing. Nearly all of them died of puerperal fever. He concluded that the fever can be also caused by ‘putrid matter derived from living organisms’.

Logical deduction usually moves from the general to the particular and requires that if the premises are true, the conclusion must be true and that to accept the premises and to deny the conclusion is to contradict oneself. It depends on a priori reasoning. Its aim is to produce certain truth.

Induction (the general method of science) usually moves from the particular to the general (from the observed to the unobserved, from the past to the future or from partial experience to claims about general experience). Even if the premises are true, the conclusion might be false, and there is no contradiction in accepting the premises and denying the conclusion. It is based on a posteriori reasoning and is the method by which a general law or principle is inferred from observed particular instances. The problem with inductive argument is that the conclusion is not guaranteed truth (the Absolute Truth beloved of metaphysicians), even though all one’s observations may all be correct.

In order to find the cause of the fever, Semmelweis collected data, analysed it and formed and tested various hypotheses on that basis. These hypotheses were thought up to account for observed facts. Further, they gave no deductively conclusive evidence, but only more or less strong confirmation for their applicability. Semmelweis did not restrict his study to events at his hospital but to better understand these events, took into consideration births before the mothers arrived at the hospital and the incidence of puerperal fever outside the hospital. Because he proceeded inductively, Semmelweis was able to retain, reshape or discard premises in the light of incorrect conclusions. Even when he had identified the cause of the fever’s spread in the hospital, and did a further testing of his hypothesis using ‘putrid matter derived from living organisms’, not all of the women subjected to it died.

In cognition, induction and deduction are not self-sufficient methods, but are closely interconnected and interdependent.

As Lenin wrote:

‘From living perception to abstract thought, and from this to practice, – such is the dialectical path of the cognition of truth, of the cognition of objective reality. Kant disparages knowledge in order to make way for faith: Hegel exalts knowledge, asserting that knowledge is knowledge of God. The materialist exalts the knowledge of matter, of nature…’

Lenin on matter: part six

 

The fundamental characteristic of materialism is that it starts from the objectivity of science, from the recognition of objective reality reflected by science, whereas idealism needs “detours” in order, in one way or another, to “deduce” objectivity from mind, consciousness, the “psychical”.

Sensation is an image of matter in motion. Save through sensations, we can know nothing either of the forms of matter or of the forms of motion; sensations are evoked by the action of matter in motion upon our sense-organs. That is how science views it.

“Matter disappears”, only equations remain. At a new stage of development and apparently in a new manner, we get the old Kantian idea: reason prescribes laws to nature.

Materialism and Empirio-Criticism: Critical Comments on a Reactionary Philosophy, 1908, Progress Publishers, Moscow, 1975, pp. 275, 282, 288

Lenin on matter: part five

The ‘indivisible’ atom. ‘With each epoch-making discovery even in the sphere of natural science, (materialism) has to change its form’ (Engels)

The destructibility of the atom, its inexhaustibility, the mutability of all forms of matter and of its motion, have always been the stronghold of dialectical materialism. All boundaries in nature are conditional, relative, movable, and express the gradual approximation of our mind towards knowledge of matter. But this does not in any way prove that nature, matter itself, is a symbol, a conventional sign, i.e., the product of our mind. The electron is to the atom as a full stop in this book is to the size of a building 200 feet long, 100 feet broad, and 50 feet high (Lodge); it moves with a velocity as high as 270,000 kilometres per second; its mass is a function of its velocity; it makes 500 trillion revolutions in a second – all this is much more complicated than the old mechanics; but it is, nevertheless, movement of matter in space and time. Human reason has discovered many amazing things in nature and will discover still more, and will thereby increase its power over nature. But this does not mean that nature is the creation of our mind or of abstract mind, i.e., of Ward’s God, Bogdanov’s “substitution”, etc.

Part Five/To be continued…

Lenin on matter: part four

Lenin in Red Square, 1920

Matter has disappeared, they tell us, wishing from this to draw epistemological conclusions. But has thought remained? – we ask. If not, if with the disappearance of matter thought has also disappeared, if with the disappearance of the brain and nervous system ideas and sensations, too, have disappeared – then it follows that everything has disappeared, and your argument as a sample of “thought” (or lack of thought) has disappeared. But if thought has remained – if it is assumed that with the disappearance of matter, thought (idea, sensation, etc.) does not disappear, then you have surreptitiously gone over to the standpoint of philosophical idealism. And this always happens with people who wish, for the sake of “economy”, to conceive of motion without matter, for tacitly, by the very fact that they continue their argument, they are acknowledging the existence of thought after the disappearance of matter. This means that a very simple, or a very complex philosophical idealism is taken as a basis; a very simple one, if it is a case of frank solipsism (I exist, and the world is only my sensation): a very complex one, if instead of the thought, ideas and sensations of a living person, a dead abstraction is taken, that is, nobody’s thought, nobody’s idea, nobody’s sensation, but thought in general (the Absolute Idea, the Universal Will, etc.), sensation as an indeterminate “element”, the “psychical”, which is substituted for the whole of physical nature, etc., etc. Thousands of shades of varieties of philosophical idealism are possible and it is always possible to create a thousand and first shade; and to the author of this thousand and first little system (empirio-monism, for example) what distinguishes it from the rest may appear important. From the standpoint of materialism, however, these distinctions are absolutely unessential. What is essential is the point of departure. What is essential is that the attempt to think of motion without matter smuggles in thought divorced from matter – and that is philosophical idealism.

Part Four/To be continued…

David Hume, ‘The problem of induction’ and the workingman’s sausage

sausage_2001253c

David Hume is credited with developing induction. He argued that our inductive generalisations rest on the assumption that unobserved cases will follow the patterns that we discovered in observed cases but that one cannot make induction deductively certain. We cannot know that nature is uniform.

Hume distinguished between relations of ideas and matters of fact. He regarded deductive reasoning as demonstrative (involving certainty, established through relations of ideas) and inductive reasoning as probable (involving matters of fact, known by experience).

Hume denied the objective character of causality, arguing that there is no necessary relationship between cause and effect.

He insisted that philosophy cannot go beyond experience and that there is no solution to the ‘problem of induction’ which he set as a syllogism. He asked how we can move from a first premise that all observed A’s have been B to the conclusion that all A’s without restriction have been, are, and will be B.

He thought it can be addressed from two perspectives – that of redundancy (‘All A’s have been observed’), which is disqualified because it cannot be an argument from experience, and that of ‘the principle of the uniformity of nature’.

He also ruled this out because it could only be known to be true by a question-begging appeal to arguments of the very kind here in question (Nature has always been uniform. How does one know? Because it has always been uniform.). Further, such a premise would have to imply that all the A’s experienced by anyone constitute in all respects a perfectly representative sample of A’s.

Hume’s ‘moral’ conclusion was that argument from experience must be without rational foundation.

‘He seems nevertheless to have felt few scruples over the apparent inconsistency of going on to insist, first, that such argument is grounded in the deepest instincts of our nature, and, second, that the rational man everywhere proportions his belief to the evidence – evidence which in practice crucially includes that outcome of procedures alleged earlier to be without rational foundation…Argument from experience should be thought of not as an irreparably fallacious attempt to deduce conclusions necessarily wider than available premises can contain, but rather as a matter of following a tentative and self-correcting rule, a rule that is part of the very paradigm of inquiring rationality – that one would think that other A’s have been and will be the same, until and unless a particular reason is discovered to revise these expectations.’1

Lenin wrote that the sophism of idealist philosophy is that it regards sensation as being not the connection between consciousness and the external world, but a barrier between the two, not an image of the external phenomenon, but the sole entity.2

Whence arises the relations of ideas in deduction – from other ideas, or from within a form of matter which is utterly part of the world?

The (theoretically) absolute truth in nature is approached (the deepening of truth, inseparable from change and uncertainty) through a compound of relative truths by a process of sensory experience, brain processing of that experience and the testing of the resulting ideas in practice.

And this debate, which ultimately traces to that concerning the precedence of matter (objective reality) or consciousness as thought over the other, is directly related to ideology.

‘The workingman who eats sausage and receives a hundred sous a day knows very well that he is robbed by the employer and is nourished by pork meat, that the employer is a robber and that the sausage is pleasant to the taste and nourishing to the body. Not at all, say the bourgeois sophists, whether they are called Pyrrho, Hume or Kant. His opinion is personal, an entirely subjective opinion; he might with equal reason maintain that the employer is his benefactor and that the sausage consists of chopped leather, for he cannot know things-in-themselves.

The question is not properly put, that is the whole trouble…In order to know an object, man must first verify whether his senses deceive him or not…The chemists have gone deeper – they have penetrated into bodies, they have analysed them, decomposed them into their elements, and then performed the reverse procedure, they have recomposed them from their elements. And from the moment that man is able to produce things for his own use from these elements, he may, as Engels says, assert that he knows the things-in-themselves. The God of the Christians, if he existed and if he had created the world, could do no more.’3

Now it is also the case that there can be nothing intermediate to an assertion and a denial. We must either assert or deny any single predicate of any single subject. The quickest way to show this is by defining truth and falsity. Well, falsity is the assertion that that which is is not or that that which is not is and truth is the assertion that that which is is and that that which is not is not. Thus anyone who asserts anything to be or not to be is either telling the truth or telling a falsehood. On the other hand, neither that which is is said either not to be or to be nor is that which is not.

And if there were an intermediate of contradictory statements, then it would either be like grey between black and white or like the non-man-non-horse between man and horse.

It is admitted that the law of identity expresses only a one-sided determinateness, that it contains only formal truth, a truth which is abstract, incomplete. In this correct judgement, however, it is immediately implied that truth is complete only in the unity of identity with difference, and hence consists only in this unity.

Contemporary fideism does not at all reject science; all it rejects is the “exaggerated claims” of science, to wit, its claim to objective truth. If objective truth exists (as the materialists think), if natural science, reflecting the outer world in human “experience”, is alone capable of giving us objective truth, then all fideism is absolutely refuted. But if there is no objective truth, if truth (including scientific truth) is only an organising form of human experience, then this in itself is an admission of the fundamental premise of clericalism, the door is thrown open for it, and a place is cleared for the “organising forms” of religious experience.

Dialectics—as Hegel in his time explained—contains an element of relativism, of negation, of scepticism, but is not reducible to relativism. The materialist dialectics of Marx and Engels certainly does contain relativism, but is not reducible to relativism, that is, it recognises the relativity of all our knowledge, not in the sense of denying objective truth, but in the sense that the limits of approximation of our knowledge to this truth are historically conditional.

The standpoint of life, of practice, should be first and fundamental in the theory of knowledge. And it inevitably leads to materialism, sweeping aside the endless fabrications of professorial scholasticism. Of course, we must not forget that the criterion of practice can never, in the nature of things, either confirm or refute any human idea completely. This criterion too is sufficiently “indefinite” not to allow human knowledge to become “absolute”, but at the same time it is sufficiently definite to wage a ruthless fight on all varieties of idealism and agnosticism. If what our practice confirms is the sole, ultimate and objective truth, then from this must follow the recognition that the only path to this truth is the path of science, which holds the materialist point of view.

…dialectical materialism insists on the approximate, relative character of every scientific theory of the structure of matter and its properties; it insists on the absence of absolute boundaries in nature, on the transformation of moving matter from one state into another, that from our point of view is apparently irreconcilable with it, and so forth. However bizarre from the standpoint of “common sense” the transformation of imponderable ether into ponderable matter and vice versa may appear, however “strange” may seem the absence of any other kind of mass in the electron save electromagnetic mass, however extraordinary may be the fact that the mechanical laws of motion are confined only to a single sphere of natural phenomena and are subordinated to the more profound laws of electromagnetic phenomena, and so forth – all this is but another corroboration of dialectical materialism. …The electron is as inexhaustible as the atom, nature is infinite but it infinitely exists. And it is this sole categorical, this sole unconditional recognition of nature’s existence outside the mind and perception of man that distinguishes dialectical materialism from relativist agnosticism and idealism.

Materialism and idealism differ in their answers to the question of the source of our knowledge and of the relation of knowledge (and of the “mental” in general) to the physical world; while the question of the structure of matter, of atoms and electrons, is a question that concerns only this “physical world”. When the physicists say “matter disappears” they mean that hitherto science reduced its investigations of the physical world to three ultimate concepts: matter, electricity and ether; now only the two former remain. For it has become possible to reduce matter to electricity; the atom can be explained as resembling an infinitely small solar system, within which negative electrons move around a positive electron with a definite (and, as we have seen, enormously large) velocity. It is consequently possible to reduce the physical world from scores of elements to two or three elements (inasmuch as positive and negative electrons constitute “two essentially distinct kinds of matter”, as the physicist Pellat says – Rey, op. cit., pp. 294-95). Hence natural science leads to the “unity of matter” (ibid.) – such is the real meaning of the statement about the disappearance of matter, its replacement by electricity, etc., which is leading so many people astray. “Matter disappears” means that the limit within which we have hitherto known matter disappears and that our knowledge is penetrating deeper; properties of matter are likewise disappearing which formerly seemed absolute, immutable, and primary (impenetrability, inertia, mass, etc.) and which are now revealed to be relative and characteristic only of certain states of matter. For the sole “property” of matter with whose recognition philosophical materialism is bound up is the property of being an objective reality, of existing outside the mind.
