How to retain the relevance of metaphysics (the primacy of consciousness over matter)

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

How to retain the primacy of consciousness over matter: attach a carefully worded lie to the greatest scientific hypothesis – thus Kant’s ‘Copernican turn’

Kant wrote: ‘…the fundamental laws of the motions of the heavenly bodies gave established certainty to what Copernicus had at first assumed only as an hypothesis, and at the same time yielded proof of the invisible force (the Newtonian attraction) which holds the universe together. The latter would have remained for ever undiscovered if Copernicus had not dared, in a manner contradictory of the senses, but yet true, to seek the observed movements, not in the heavenly bodies, but in the spectator. The change in point of view, analogous to this hypothesis, which is expounded in the Critique, I put forward in this preface as an hypothesis only, in order to draw attention to the character of these first attempts at such a change, which are always hypothetical. But in the Critique itself it will be proved, apodeictically not hypothetically, from the nature of our representations of space and time and from the elementary concepts of the understanding.’ Immanuel Kant, Preface to the Second Edition, Immanuel Kant’s Critique of Pure Reason, Trans., Norman Kemp Smith, Macmillan, London, 1987, 25 (Footnote)

and ‘We must therefore make trial whether we may not have more success in the tasks of metaphysics, if we suppose that objects must conform to our knowledge. This would agree better with what is desired, namely, that it should be possible to have knowledge of objects a priori, determining something in regard to them prior to their being given. We should then be proceeding precisely on the lines of Copernicus’ primary hypothesis. Failing of satisfactory progress in explaining the movements of the heavenly bodies on the supposition that they all revolved round the spectator, he tried whether he might not have better success if he made the spectator to revolve and the stars to remain at rest. A similar experiment can be tried in metaphysics, as regards the intuition of objects. If intuition must conform to the constitution of the objects, I do not see how we could know anything of the latter a priori; but if the object (as object of the senses) must conform to the constitution of our faculty of intuition, I have no difficulty in conceiving such a possibility.’ (22)

Kant’s incorrect assertion that Copernicus had sought the observed movements in the spectator is not the crucial point – it is that Kant thereby had the pretext to give priority over matter to ‘mind’/consciousness – via concepts and the ‘forms of intuition’. Copernicus’ hypothesis is an objective hypothesis about the world, the functioning of which Copernicus recognised requires neither the spectator – nor their ‘mind’/consciousness.1

In On the Revolutions of Heavenly Spheres, Copernicus a couple of times referred to the spectator: ‘For every apparent change in place occurs on account of the movement either of the thing seen or of the spectator, or on account of the necessarily unequal movement of both. For no movement is perceptible relatively to things moved equally in the same directions – I mean relatively to the thing seen and the spectator.’ Nicolaus Copernicus, On the Revolutions of Heavenly Spheres, Ed., Stephen Hawking, Running Press, Philadelphia, 2002, 12

But the spectator did not figure in his hypothesis itself: ‘For the daily revolution appears to carry the whole universe along, with the exception of the Earth (my emphasis) and the things around it. And if you admit that the heavens possess none of this movement but that the Earth (my emphasis) turns from west to east, you will find – if you make a serious examination – that as regards the apparent rising and setting of the sun, moon, and stars the case is so. And since it is the heavens which contain and embrace all things as the place common to the universe, it will not be clear at once why movement should not be assigned to the contained rather than to the container, to the thing placed rather than to the thing providing the place.’ (12-13)

Not only – going beyond Kant’s noumenal barrier (and, most significantly, towards acquisition of knowledge of the world) – was careful observation crucial to Copernicus’ hypothesis: ‘Having recorded three positions of the planet Jupiter and evaluated them in this way, we shall set up three others in their place, which we observed with greatest care at the solar oppositions of Jupiter’ (291), not only was he entirely comfortable with appearances, repeatedly referring to them and setting out the means for counteracting them: ‘For in order to perceive this by sense with the help of artificial instruments, by means of which the job can be done best, it is necessary to have a wooden square prepared, or preferably a square made from some other more solid material, from stone or metal; for the wood might not stay in the same condition on account of some alteration in the atmosphere and might mislead the observer’ (61), he dealt with the reciprocal relationships between sun, earth and moon, irrespective of which body was moving: ‘It is of no importance if we take up in an opposite fashion what others have demonstrated by means of a motionless earth and a giddy world and race with them toward the same goal, since things related reciprocally happen to be inversely in harmony with one another’ (60), even writing ‘And for this reason we can call the former movement of the sun – to use the common expression – the regular and simple movement’ (161).


The Sage of Königsberg steps forth: ‘it is clearly shown, that if I remove the thinking subject the whole corporeal world must at once vanish: it is nothing save an appearance in the sensibility of our subject and a mode of its representations’ (Immanuel Kant’s Critique of Pure Reason, op. cit., 354).

1. Bertrand Russell wrote that Kant should have ‘spoken of a “Ptolemaic counter-revolution (my italics)”, since he put man back at the centre from which Copernicus had dethroned him..’ Bertrand Russell, Human Knowledge, Simon and Schuster, New York, 1948, 9, in Paul Redding, Hegel’s Hermeneutics, Cornell University Press, Ithaca, 1996, 3. Kant’s calculated nonsense was replicated by A.C.Ewing ‘“Just as Copernicus taught that the movement round the earth which men had ascribed to the sun was only an appearance due to our own movement,” stated Ewing, “so Kant taught that space and time which men had ascribed to reality were only appearances due to ourselves. The parallel is correct.”’ Ibid. Space is the objective distribution of matter, time (not the measure of time) is the objective movement of matter in space. Space, time, matter and motion (all objective) are inseparable. Kant’s crucial spectator with their consciousness is the product of these.

Lenin – “matter has disappeared”: part one

 

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 latter 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,1 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.

The error of Machism in general, as of the Machist new physics, is that it ignores this basis of philosophical materialism and the distinction between metaphysical materialism and dialectical materialism. The recognition of immutable elements, “of the immutable essence of things”, and so forth, is not materialism, but metaphysical, i.e., anti-dialectical, materialism. That is why J. Dietzgen emphasised that the “subject-matter of science is endless”, that not only the infinite, but the “smallest atom” is immeasurable, unknowable to the end, inexhaustible, “for nature in all her parts has no beginning and no end” (Kleinere philosophische Schriften, S. 229-30). That is why Engels gave the example of the discovery of alizarin in coal tar and criticised mechanical materialism. In order to present the question in the only correct way, that is, from the dialectical materialist standpoint, we ask: Do electrons, ether and so on exist as objective realities outside the human mind or not? The scientists will also have to answer this question unhesitatingly; and they do invariably answer it in the affirmative, just as they unhesitatingly recognise that nature existed prior to man and prior to organic matter. Thus, the question is decided in favour of materialism, for the concept matter, as we already stated, epistemologically implies nothing but objective reality existing independently of the human mind and reflected by it.

Engels on dialectics, part six: science and philosophy

 

Natural scientists believe that they free themselves from philosophy by ignoring it or abusing it. They cannot, however, make any headway without thought, and for thought they need thought determinations. But they take these categories unreflectingly from the common consciousness of so-called educated persons, which is dominated by the relics of long obsolete philosophies, or from the little bit of philosophy compulsorily listened to at the University (which is not only fragmentary, but also a medley of views of people belonging to the most varied and usually the worst schools), or from uncritical and unsystematic reading of philosophical writings of all kinds. Hence they are no less in bondage to philosophy, but unfortunately in most cases to the worst philosophy, and those who abuse philosophy most are slaves to precisely the worst vulgarised relics of the worst philosophies.

*      *      *

Natural scientists may adopt whatever attitude they please, they are still under the domination of philosophy. It is only a question whether they want to be dominated by a bad, fashionable philosophy or by a form of theoretical thought which rests on acquaintance with the history of thought and its achievements.

‘Physics, beware of metaphysics’, is quite right, but in a different sense.

Natural scientists allow philosophy to prolong an illusory existence by making shift with the dregs of the old metaphysics. Only when natural and historical science has become imbued with dialectics will all the philosophical rubbish – other than the pure theory of thought – be superfluous, disappearing in positive science.

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.

Engels on dialectics, part four: identity

Abstract identity (a=a; and negatively, a cannot be simultaneously equal and unequal to a) is likewise inapplicable in organic nature. The plant, the animal, every cell is at every moment of its life identical with itself and yet becoming distinct from itself, by absorption and excretion of substances, by respiration, by cell formation and death of cells, by the process of circulation taking place, in short, by a sum of incessant molecular changes which make up life and the sum-total of whose results is evident to our eyes in the phases of life – embryonic life, youth, sexual maturity, process of reproduction, old age, death. The further physiology develops, the more important for it become (sic) these incessant, infinitely small changes, and hence the more important for it also the consideration of difference within identity, and the old abstract standpoint of formal identity, that an organic being is to be treated as something simply identical with itself, as something constant, becomes out of date. Nevertheless, the mode of thought based thereon, together with its categories, persists. But even in inorganic nature identity as such is in reality non-existent. Every body is continually exposed to mechanical, physical, and chemical influences, which are always changing it and modifying its identity. Abstract identity, with its opposition to difference, is in place only in mathematics – an abstract science which is concerned with creations of thought, even though they are reflections of reality – and even there it is continually being sublated. Hegel, Enzyklopädie, I, p. 235. The fact that identity contains difference within itself is expressed in every sentence, where the predicate is necessarily different from the subject; the lily is a plant, the rose is red. where, either in the subject or in the predicate there is something that is not covered by the predicate or the subject. Hegel, p. 231. That from the outset identity with itself requires difference from everything else as its complement, is self-evident.

Continual change, i.e., sublation of abstract identity with itself, is also found in so-called inorganic nature. Geology is its history. On the surface, mechanical changes (denudation, frost), chemical changes (weathering); internally, mechanical changes (pressure), heat (volcanic), chemical (water, acids, binding substances); on a large scale – upheavals, earthquakes, etc. The slate of today is fundamentally different from the ooze from which it is formed, the chalk from the loose microscopic shells that compose it, even more so limestone, which indeed according to some is of purely organic origin, and sandstone from the loose sea sand, which again is derived from disintegrated granite, etc., not to speak of coal.

The law of identity in the old metaphysical sense is the fundamental law of the old outlook: a = a. Each thing is equal to itself. Everything was permanent, the solar system, stars, organisms. This law has been refuted by natural science bit by bit in each separate case, but theoretically it still prevails and is still put forward by the supporters of the old in opposition to the new: a thing cannot simultaneously be itself and something else. And yet the fact that true, concrete identity includes difference, change, has recently been shown in detail by natural science (see above).

Abstract identity, like all metaphysical categories, suffices for everyday use, where small dimensions or brief periods of time are in question; the limits within which it is usable differ in almost every case and are determined by the nature of the object; for a planetary system, where in ordinary astronomical calculation the ellipse can be taken as the basic form for practical purposes without error, they are much wider than for an insect that completes its metamorphosis in a few weeks. (Give other examples, e.g., alteration of species, which is reckoned in periods of thousands of years.) For natural science in its comprehensive role, however, even in each single branch, abstract identity is totally inadequate, and although on the whole it has now been abolished in practice, theoretically it still dominates people’s minds, and most natural scientists imagine that identity and difference are irreconcilable opposites, instead of one-sided poles which represent the truth only in their reciprocal action, in the inclusion of difference within identity.

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.

Engels on dialectics, part three: chance and necessity

Another opposition in which metaphysics is entangled is that of chance and necessity. What can be more sharply contradictory than these two thought determinations? How is it possible that both are identical, that the accidental is necessary, and the necessary is also accidental? Common sense, and with it the majority of natural scientists, treats necessity and chance as determinations that exclude each other once for all. A thing, a circumstance, a process is either accidental or necessary, but not both. Hence both exist side by side in nature; nature contains all sorts of objects and processes, of which some are accidental, the others necessary, and it is only a matter of not confusing the two sorts with each other. Thus, for instance, one assumes the decisive specific characters to be necessary, other differences between individuals of the same species being termed accidental, and this holds good of crystals as it does for plants and animals. Then again the lower group becomes accidental in relation to the higher, so that it is declared to be a matter of chance how many different species are included in the genus felis or equus, or how many genera and orders there are in a class, and how many individuals of each of these species exist, or how many different species of animals occur in a given region, or what in general the fauna and flora are like. And then it is declared that the necessary is the sole thing of scientific interest and that the accidental is a matter of indifference to science. That is to say: what can be brought under laws, hence what one knows, is interesting; what cannot be brought under laws, and therefore what one does not know, is a matter of indifference and can be ignored. Thereby all science comes to an end, for it has to investigate precisely that which we do not know. That is to say: what can be brought under general laws is regarded as necessary, and what cannot be so brought as accidental. Anyone can see that this is the same sort of science as that which proclaims natural what it can explain, and ascribes what it cannot explain to supernatural causes; whether I term the cause of the inexplicable chance, or whether I term it God, is a matter of complete indifference as far as the thing itself is concerned. Both are only equivalents for: I do not know, and therefore do not belong to science. The latter ceases where the requisite connection is wanting.

In opposition to this view there is determinism, which passed from French materialism into natural science, and which tries to dispose of chance by denying it altogether. According to this conception only simple, direct necessity prevails in nature. That a particular pea-pod contains five peas and not four or six, that a particular dog’s tail is five inches long and not a whit longer or shorter, that this year a particular clover flower was fertilised by a bee and another not, and indeed by precisely one particular bee and at a particular time, that a particular windblown dandelion seed has sprouted and another not, that last night I was bitten by a flea at four o’clock in the morning, and not at three or five o’clock, and on the right shoulder and not on the left calf – these are all facts which have been produced by an irrevocable concatenation of cause and effect, by an unshatterable necessity of such a nature indeed that the gaseous sphere, from which the solar system was derived, was already so constituted that these events had to happen thus and not otherwise. With this kind of necessity we likewise do not get away from the theological conception of nature. Whether with Augustine and Calvin we call it the eternal decree of God, or Kismet as the Turks do, or whether we call it necessity, is all pretty much the same for science. There is no question of tracing the chain of causation in any of these cases; so we are just as wise in one as in another, the so-called necessity remains an empty phrase, and with it – chance also remains what it was before. As long as we are not able to show on what the number of peas in the pod depends, it remains just a matter of chance, and the assertion that the case was foreseen already in the primordial constitution of the solar system does not get us a step further. Still more. A science which was to set about the task of following back the casus (sic) of this individual pea-pod in its causal concatenation would be no longer science but pure trifling; for this same pea-pod alone has in addition innumerable other individual, accidentally appearing qualities: shade of colour, thickness and hardness of the pod, size of the peas, not to speak of the individual peculiarities revealed by the microscope. The one pea-pod, therefore, would already provide more causal connections for following up than all the botanists in the world could solve.

Hence chance is not here explained by necessity, but rather necessity is degraded to the production of what is merely accidental. If the fact that a particular pea-pod contains six peas, and not five or seven, is of the same order as the law of motion of the solar system, or the law of the transformation of energy, then as a matter of fact chance is not elevated into necessity, but rather necessity degraded into chance. Furthermore, however much the diversity of the organic and inorganic species and individuals existing side by side in a given area may be asserted to be based on irrefragable necessity, for the separate species and individuals it remains what it was before, a matter of chance. For the individual animal it is a matter of chance, where it happens to be born, what environment it finds for living, what enemies and how many of them threaten it. For the mother plant it is a matter of chance whither the wind scatters its seeds, and, for the daughter plant, where the seed finds soil for germination; and to assure us that here also everything rests on irrefragable necessity is a poor consolation. The jumbling together of natural objects in a given region, still more in the whole world, for all the primordial determination from eternity, remains what it was before – a matter of chance.

In contrast to both conceptions, Hegel came forward with the hitherto quite unheard-of propositions that the accidental has a cause because it is accidental, and just as much also has no cause because it is accidental; that the accidental is necessary, that necessity determines itself as chance, and, on the other hand, this chance is rather absolute necessity. (Logik, II, Book III, 2: Reality.) Natural science has simply ignored these propositions as paradoxical trifling, as self-contradictory nonsense, and, as regards theory, has persisted on the one hand in the barrenness of thought of Wolffian metaphysics, according to which a thing is either accidental or necessary, but not both at once; or, on the other hand, in the hardly less thoughtless mechanical determinism which in words denies chance in general only to recognise it in practice in each particular case.

While natural science continued to think in this way, what did it do in the person of Darwin?

Darwin in his epoch-making work, set out from the widest existing basis of chance. Precisely the infinite, accidental differences between individuals within a single species, differences which become accentuated until they break through the character of the species, and whose immediate causes even can be demonstrated only in extremely few cases, compelled him to question the previous basis of all regularity in biology, viz., the concept of species in its previous metaphysical rigidity and unchangeability. Without the concept of species, however, all science was nothing. All its branches needed the concept of species as basis: human anatomy and comparative anatomy – embryology, zoology, palaeontology, botany, etc., what were they without the concept of species? All their results were not only put in question but directly set aside. Chance overthrows necessity, as conceived hitherto. The previous idea of necessity breaks down. To retain it means dictatorially to impose on nature as a law a human arbitrary determination that is in contradiction to itself and to reality, it means to deny thereby all inner necessity in living nature, it means generally to proclaim the chaotic kingdom of chance to be the sole law of living nature.

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.

…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.

Engels on dialectics

(The general nature of dialectics to be developed as the science of inter-connections, in contrast to metaphysics.)

It is, therefore, from the history of nature and human society that the laws of dialectics are abstracted. For they are nothing but the most general laws of these two aspects of historical development, as well as of thought itself. And indeed they can be reduced in the main to three:

The law of the transformation of quantity into quality and vice versa;

The law of the interpenetration of opposites;

The law of the negation of the negation.

All three are developed by Hegel in his idealist fashion as mere laws of thought: the first, in the first part of his Logic, in the Doctrine of Being; the second fills the whole of the second and by far the most important part of his Logic, The Doctrine of Essence; finally the third figures as the fundamental law for the construction of the whole system. The mistake lies in the fact that these laws are foisted on nature and history as laws of thought, and not deduced from them. This is the source of the whole forced and often outrageous treatment; the universe, willy-nilly, has to conform to a system of thought which itself is only the product of a definite stage of evolution of human  thought. If we turn the thing round, then everything becomes simple, and the dialectical laws that look so extremely mysterious in idealist philosophy at once become simple and clear as noonday.

Moreover, anyone who is even only slightly acquainted with Hegel will be aware that in hundreds of passages Hegel is capable of giving the most striking individual illustrations of the dialectical laws from nature and history.

We are not concerned here with writing a handbook of dialectics, but only with showing that the dialectical laws are real laws of development of nature, and therefore are valid also for theoretical natural science. …

1. The law of the transformation of quantity into quality and vice versa. For our purpose, we can express this by saying that in nature, in a manner exactly fixed for each individual case, qualitative changes can only occur by the quantitative addition or quantitative subtraction of matter or motion (so-called energy).

All qualitative differences in nature rest on differences of chemical composition or on different quantities or forms of motion (energy) or, as is almost always the case, on both. Hence it is impossible to alter the quality of a body without addition or subtraction of matter or motion, i.e., without quantitative alteration of the body concerned. In this form, therefore, Hegel’s mysterious principle appears not only quite rational but even rather obvious.
