Lenin: the theory of knowledge of dialectical materialism – part three

Immanuel Kant by Karl Friedrich Hagemann, 1801, marble, Kunsthalle, Hamburg

The ‘Thing-in-Itself’ (continued)

The question at issue is Marx’s second Thesis on Feuerbach and Plekhanov’s translation of the word Diesseitigkeit.

Here is the second Thesis:

“The question whether objective truth can be attributed to human thinking is not a question of theory, but is a practical question. In practice man must prove the truth, i.e., the reality and power, the ‘this-sidedness’ of his thinking. The dispute over the reality or non-reality of thinking which is isolated from practice is a purely scholastic question.”

Instead of “prove the this-sidedness of thinking” (a literal translation), Plekhanov has: prove that thinking “does not stop at this side of phenomena”. And Mr. V. Chernov cries: “The contradiction between Marx and Engels has been eliminated very simply…It appears as though Marx, like Engels, asserted the knowability of things-in-themselves and the ‘other-sidedness’ of thinking” (loc. cit., p. 34, note).

What can be done with a Voroshilov whose every phrase makes confusion worse confounded! It is sheer ignorance, Mr. Victor Chernov, not to know that all materialists assert the knowability of things-in-themselves. It is ignorance, Mr. Victor Chernov, or infinite slovenliness, to skip the very first phrase of the thesis and not to realise that the “objective truth” (gegenständliche Wahrheit) of thinking means nothing else than the existence of objects (“things-in-themselves”) truly reflected by thinking. It is sheer illiteracy, Mr. Victor Chernov, to assert that from Plekhanov’s paraphrase (Plekhanov gave a paraphrase and not a translation) “it appears as though” Marx defended the other-sidedness of thought. Because only the Humeans and the Kantians confine thought to “this side of phenomena”. But for all materialists, including those of the seventeenth century whom Bishop Berkeley demolished (see Introduction), “phenomena” are “things-for-us” or copies of the “objects in themselves”. Of course, Plekhanov’s free paraphrase is not obligatory for those who desire to know Marx himself, but it is obligatory to try to understand what Marx meant and not to prance about like a Voroshilov.

Lenin: the theory of knowledge of dialectical materialism – part two

Immanuel Kant by Karl Friedrich Hagemann, 1801, marble, Kunsthalle, Hamburg

The ‘thing-in-Itself’

In the theory of knowledge, as in every other sphere of science, we must think dialectically, that is, we must not regard our knowledge as ready-made and unalterable, but must determine how knowledge emerges from ignorance, how incomplete, inexact knowledge becomes more complete and more exact.

Once we achieve the point of view that human knowledge develops from ignorance, we shall find millions of examples of it just as simple as the discovery of alizarin in coal tar, millions of observations not only in the history of science and technology but in the everyday life of each and every one of us that illustrate the transformation of “things-in-themselves” into “things-for-us”, the appearance of “phenomena” when our sense-organs experience an impact from external objects, the disappearance of “phenomena” when some obstacle prevents the action upon our sense-organs of an object which we know to exist. The sole and unavoidable deduction to be made from this – a deduction which all of us make in everyday practice and which materialism deliberately places at the foundation of its epistemology – is that outside us, and independently of us, there exist objects, things, bodies and that our perceptions are images of the external world.

Lenin: the theory of knowledge of dialectical materialism

Sensations and Complexes of Sensations

For every scientist who has not been led astray by professorial philosophy, as well as for every materialist, sensation is indeed the direct connection between consciousness and the external world; it is the transformation of the energy of external excitation into the fact of consciousness. This transformation has been, and is, observed by each of us a million times on every hand. The sophism of idealist philosophy consists in the fact that it regards sensation as being not the connection between consciousness and the external world, but a fence, a wall, separating consciousness from the external world – not an image of the external phenomenon corresponding to the sensation, but as the “sole entity”. Avenarius gave but a slightly changed form to this old sophism, which had been already worn threadbare by Bishop Berkeley. Since we do not yet know all the conditions of the connection we are constantly observing between sensation and matter organised in a definite way, let us therefore acknowledge the existence of sensation alone – that is what the sophism of Avenarius amounts to.

Lenin: Is motion without matter conceivable? – part two

Let us imagine a consistent idealist who holds, let us say, that the entire world is his sensation, his idea, etc. (if we take “nobody’s” sensation or idea, this changes only the variety of philosophical idealism but not its essence). The idealist would not even think of denying that the world is motion, i.e., the motion of his thoughts, ideas, sensations. The question as to what moves, the idealist will reject and regard as absurd: what is taking place is a change of his sensations, his ideas come and go, and nothing more. Outside him there is nothing. “It moves” – and that is all. It is impossible to conceive a more “economical” way of thinking. And no proofs, syllogisms, or definitions are capable of refuting the solipsist if he consistently adheres to his view.

The fundamental distinction between the materialist and the adherent of idealist philosophy consists in the fact that the materialist regards sensation, perception, idea, and the mind of man generally, as an image of objective reality. The world is the movement of this objective reality reflected by our consciousness. To the movement of ideas, perceptions, etc., there corresponds the movement of matter outside me. The concept matter expresses nothing more than the objective reality which is given us in sensation. Therefore, to divorce motion from matter is equivalent to divorcing thought from objective reality, or to divorcing my sensations from the external world – in a word, it is to go over to idealism. The trick which is usually performed in denying matter, in assuming motion without matter, consists in ignoring the relation of matter to thought. The question is presented as though this relation did not exist, but in reality it is introduced surreptitiously; at the beginning of the argument it remains unexpressed, but subsequently crops up more or less imperceptibly.

Lenin: Is motion without matter conceivable?

8. Two Black Holes Dancing in 3C 75. Particle jets are moving at 1200 kilometres per second.

The fact that philosophical idealism is attempting to make use of the new physics, or that idealist conclusions are being drawn from the latter, is due not to the discovery of new kinds of substance and force, of matter and motion, but to the fact that an attempt is being made to conceive motion without matter. And it is the essence of this attempt which our Machists fail to examine. They were unwilling to take account of Engels’ statement that “motion without matter is unthinkable”. J. Dietzgen in 1869, in his The Nature of the Workings of the Human Mind, expressed the same idea as Engels, although, it is true, not without his usual muddled attempts to “reconcile” materialism and idealism. Let us leave aside these attempts, which are to a large extent to be explained by the fact that Dietzgen is arguing against Büchner’s non-dialectical materialism, and let us examine Dietzgen’s own statements on the question under consideration. He says: “They [the idealists] want to have the general without the particular, mind without matter, force without substance, science without experience or material, the absolute without the relative” (Das Wesen der menschlichen Kopfarbeit, 1903, S. 108). Thus the endeavour to divorce motion from matter, force from substance, Dietzgen associates with idealism, ranking it with the endeavour to divorce thought from the brain. “Liebig,” Dietzgen continues, “who is especially fond of straying from his inductive science into the field of speculation, says in the spirit of idealism: ‘force cannot be seen’” (109). “The spiritualist or the idealist believes in the spiritual, i.e., ghost-like and inexplicable, nature of force” (110). “The antithesis between force and matter is as old as the antithesis between idealism and materialism” (111). “Of course, there is no force without matter, no matter without force; forceless matter and matterless force are absurdities. If idealist natural scientists believe in the immaterial existence of forces, then on this point they are not natural scientists…but seers of ghosts” (114).

Thus we see that scientists who were prepared to assume that motion is conceivable without matter were to be encountered forty years ago too, and that “on this point” Dietzgen declared them to be seers of ghosts. What, then, is the connection between philosophical idealism and the divorce of matter from motion, the separation of substance from force? Is it not “more economical”, indeed, to conceive motion without matter?

How do we know the world?

From perception to thought

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: 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.

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? Part three

The prince thanking the Water sprite (artist: Richard ‘Dickie’ Doyle), from The Princess Nobody: A Tale of Fairyland (1884) by Andrew Lang

The Machists love to declaim that they are philosophers who completely trust the evidence of our sense-organs, who regard the world as actually being what it seems to us to be, full of sounds, colours, etc., whereas to the materialists, they say, the world is dead, devoid of sound and colour, and in its reality different from what it seems to be, and so forth. Such declamations, for example, are indulged in by J. Petzoldt, both in his Introduction to the Philosophy of Pure Experience and in his World Problem from the Positivist Standpoint (Weltproblem von positivistischen Standpunkte aus), 1906. Petzoldt is parroted by Mr. Victor Chernov, who waxes enthusiastic over the “new” idea. But, in fact, the Machists are subjectivists and agnostics, for they do not sufficiently trust the evidence of our sense-organs and are inconsistent in their sensationalism. They do not recognise objective reality, independent of man, as the source of our sensations. They do not regard sensations as a true copy of this objective reality, thereby coming into direct conflict with natural science and throwing the door open for fideism. On the contrary, for the materialist the world is richer, livelier, more varied than it seems, for with each step in the development of science new aspects are discovered. For the materialist, our sensations are images of the sole and ultimate objective reality, ultimate not in the sense that it has already been cognised to the end, but in the sense that there is not and cannot be any other. This view irrevocably closes the door not only to every species of fideism, but also to that professorial scholasticism which, while not recognising an objective reality as the source of our sensations, “deduces” the concept of the objective by means of such artificial verbal constructions as universal significance, socially-organised, and so on and so forth, and which is unable, and frequently unwilling, to separate objective truth from belief in sprites and hobgoblins.

The Machists contemptuously shrug their shoulders at the “antiquated” views of the “dogmatists”, the materialists, who still cling to the concept matter, which supposedly has been refuted by “recent science” and “recent positivism.” We shall speak separately of the new theories of physics on the structure of matter. But it is absolutely unpardonable to confuse, as the Machists do, any particular theory of the structure of matter with the epistemological category, to confuse the problem of the new properties of new aspects of matter (electrons, for example) with the old problem of the theory of knowledge, with the problem of the sources of our knowledge, the existence of objective truth, etc. Mach “discovered the world-elements”: red, green, hard, soft, loud, long, etc. We ask, is a man given objective reality when he sees something red or feels something hard, etc., or not? This hoary philosophical query is confused by Mach. If you hold that it is not given, you, together with Mach, inevitably sink to subjectivism and agnosticism and deservedly fall into the embrace of the immanentists, i.e., the philosophical Menshikovs. If you hold that it is given, a philosophical concept is needed for this objective reality, and this concept has been worked out long, long ago. This concept is matter. Matter is a philosophical category denoting the objective reality which is given to man by his sensations, and which is copied, photographed and reflected by our sensations, while existing independently of them. Therefore, to say that such a concept can become “antiquated” is childish talk, a senseless repetition of the arguments of fashionable reactionary philosophy. Could the struggle between materialism and idealism, the struggle between the tendencies or lines of Plato and Democritus in philosophy, the struggle between religion and science, the denial of objective truth and its assertion, the struggle between the adherents of supersensible knowledge and its adversaries, have become antiquated during the two thousand years of the development of philosophy?

Lenin: Is there objective truth? Part two

Statue of David Hume by Alexander Stoddart, 1995, bronze, in front of High Court Building, Edinburgh, Scotland

The question arises, does this denial of objective truth belong personally to Bogdanov, who refuses to own himself a Machist, or does it follow from the fundamental teachings of Mach and Avenarius? The latter is the only possible answer to the question. If only sensation exists in the world (Avenarius in 1876), if bodies are complexes of sensations (Mach, in the Analysis of Sensations), then we are obviously confronted with a philosophical subjectivism which inevitably leads to the denial of objective truth. And if sensations are called “elements” which in one connection give rise to the physical and in another to the psychical, this, as we have seen, only confuses but does not reject the fundamental point of departure of empirio-criticism. Avenarius and Mach recognise sensations as the source of our knowledge. Consequently, they adopt the standpoint of empiricism (all knowledge derives from experience) or sensationalism (all knowledge derives from sensations). But this standpoint gives rise to the difference between the fundamental philosophical trends, idealism and materialism and does not eliminate that difference, no matter in what “new” verbal garb (“elements”) the standpoint is clothed. Both the solipsist, that is, the subjective idealist, and the materialist may regard sensations as the source of our knowledge. Both Berkeley and Diderot started from Locke. The first premise of the theory of knowledge undoubtedly is that the sole source of our knowledge is sensation. Having recognised the first premise, Mach confuses the second important premise, i.e., regarding the objective reality that is given to man in his sensations, or that forms the source of man’s sensations. Starting from sensations, one may follow the line of subjectivism, which leads to solipsism (“bodies are complexes or combinations of sensations”), or the line of objectivism, which leads to materialism (sensations are images of objects, of the external world). For the first point of view, i.e., agnosticism, or, pushed a little further, subjective idealism, there can be no objective truth. For the second point of view, i.e., materialism, the recognition of objective truth is essential. This old philosophical question of the two trends, or rather, of the two possible deductions from the premises of empiricism and sensationalism, is not solved by Mach, it is not eliminated or overcome by him, but is muddled by verbal trickery with the word “element”, and the like. Bogdanov’s denial of objective truth is an inevitable consequence of Machism as a whole, and not a deviation from it.

Engels in his Ludwig Feuerbach calls Hume and Kant philosophers “who question the possibility of any cognition, or at least of an exhaustive cognition, of the world”. Engels, therefore, lays stress on what is common both to Hume and Kant, and not on what divides them. Engels states further that “what is decisive in the refutation of this [Humean and Kantian] view has already been said by Hegel” (4th Germ. ed., pp. 15–16).1 In this connection it seems to me not uninteresting to note that Hegel, declaring materialism to be “a consistent system of empiricism,” wrote: “For empiricism the external (das Äusserliche) in general is the truth, and if then a supersensible too be admitted, nevertheless knowledge of it cannot occur (soll doch eine Erkenntnis desselben [d. h. des Uebersinnlichennicht stattfinden können) and one must keep exclusively to what belongs to perception (das der Wahrnehmung Angehörige). However, this principle in its realisation (Durchführung) produced what was subsequently termed materialism. This materialism regards matter, as such, as the truly objective (das wahrhaft Objektive).”(Hegel, Encyklopädie der philosophischen Wissenschaften im Grundrisse [Encyclopaedia of the Philosophical Sciences in Outline], Werke, VI. Band [1843], S. 83. Cf. S. 122).

All knowledge comes from experience, from sensation, from perception. That is true. But the question arises, does objective reality “belong to perception,” i.e., is it the source of perception? If you answer yes, you are a materialist. If you answer no, you are inconsistent and will inevitably arrive at subjectivism, or agnosticism, irrespective of whether you deny the knowability of the thing-in-itself, or the objectivity of time, space and causality (with Kant), or whether you do not even permit the thought of a thing-in-itself (with Hume). The inconsistency of your empiricism, of your philosophy of experience, will in that case lie in the fact that you deny the objective content of experience, the objective truth of knowledge through experience.

Those who hold to the line of Kant or Hume (Mach and Avenarius are among the latter, in so far as they are not pure Berkeleians) call us, the materialists, “metaphysicians” because we recognise objective reality which is given us in experience, because we recognise an objective source of our sensations independent of man. We materialists follow Engels in calling the Kantians and Humeans agnostics, because they deny objective reality as the source of our sensations. Agnostic is a Greek word: a in Greek means “no,” gnosis “knowledge.” The agnostic says: I do not know if there is an objective reality which is reflected, imaged by our sensations; I declare there is no way of knowing this (see the words of Engels above quoted setting forth the position of the agnostic). Hence the denial of objective truth by the agnostic, and the tolerance – the philistine, cowardly tolerance – of the dogmas regarding sprites, hobgoblins, Catholic saints, and the like. Mach and Avenarius, pretentiously advancing a “new” terminology, a supposedly “new” point of view, repeat, in fact, although in a confused and muddled way, the reply of the agnostic: on the one hand, bodies are complexes of sensations (pure subjectivism, pure Berkeleianism); on the other hand, if we re-christen our sensations “elements”, we may think of them as existing independently of our sense-organs!

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.
