MORALS AND LAW
_Eternal Truths._ We refrain from offering examples of the hodge podge of stupidity and sham solemnity with which Herr Duehring regales his readers for fifty full pages as fundamental knowledge on the elements of consciousness. We merely quote the following: "He who merely conceives of thought through the medium of speech has never understood what is signified by abstract and true thought." Hence, animals are the most abstract and true thinkers, for their thought is never obscured by the importunate interference of speech. With regard to Herr Duehring's thought in particular, it may be perceived that they are but little suited to speech and that the German language in particular is quite inadequate to express them. The fourth part of his book, however, possesses some redeeming features, for here and there it offers us some comprehensible notions on the subject of morals and law in spite of the tedious and involved rhetoric. Right at the beginning we are invited to take a journey to the other heavenly bodies. Thus, the elements of morality are to be found among superhuman beings among whom exist an understanding of things and a regular system of the harmonious conduct of life. Our share in such conclusions must then be small, but there always remains a beneficent and enlarging idea in picturing that even in other spheres individual and social life follows one purpose which cannot be escaped or evaded by any intelligent living creature.
There is good reason for our altering the position of the statement that Herr Duehring's truth is good for all possible worlds from the close to the beginning of the chapter. When once the correctness of Herr Duehring's notions of morals and law have been established so as to apply to all world the beneficent notion may easily be extended to all time. Here again, however, we run across another final truth of last instance. The moral universe has "just as well as that of universal knowledge its general principles and simple elements." Moral principles are beyond history and the national distinctions of to-day ... the various truths from which in the course of development the fuller moral consciousness, and, so to speak, conscience itself is derived, can, as far as their origin is investigated, claim a similar acceptation and extent to that of mathematics and its applications. Real truths are immutable and it is folly to conceive of correct knowledge as liable to the attacks of time or of change in material conditions. "Hence the certainty of sound knowledge and the sufficiency of general acceptation forbid to doubt the absolute correctness of the fundamental principles of knowledge....
Continual doubt is in itself an evidence of weakness and is merely the expression of a barren condition of confusion, which although conscious of possessing nothing still seeks to maintain the appearance of holding on to something. Regarding morals, it denies universal principles with respect to the manifold variations in moral ideas owing to geographical and historical conditions, and thinks that with the admission of the unavoidable necessity of evil and wickedness there is no need for it to acknowledge the truth and efficiency of moral impulses. This mordant scepticism which is not directed against any false doctrine in particular, but against human capacity to recognise morality resolves itself finally into nothingness, it is no more than mere nihilism. It flatters itself that it can attain supremacy and give free rein to unprincipled pleasures by destroying moral ideas and creating chaos. It is greatly deceived, however, if merely pointing at the inevitable fate of the intellect with respect to error and truth is sufficient to show by analogy that natural liability to error does not exclude the arriving at a correct decision but rather tends to that end."
Up to now we have not commented upon Herr Duehring's pompous opinions on final truths of the last instance, sovereignty of the will, absolute certainty of knowledge, and so forth, until the matter could first be brought to an issue. Up to this point the investigation has been useful to show how far the separate assertions of the philosophy of realism had "sovereign validity" and "unrestricted claim to truth" but we now come to the question if any and what product of human knowledge can have in particular "sovereign validity" and "unrestricted claims to truth." If I speak of human knowledge I do not do so as an affront to the dwellers in other worlds whom I have not the honor to know, but only because animals have knowledge also, not sovereign, however. The dog recognises a divinity in his master, who may, however, be a great fool.
"Is human thought sovereign?" Before we can answer "yes" or "no" we must first examine what human thought is. Is it the thought of an individual man? No. It exists only as the individual thoughts of many millions of men, past, present and to come. If I now say, having comprehended the thought of all men in the future also under my concept, that it is able to understand the entire universe, if man only lasts long enough, and the organs of perception are unlimited, and the objects to be comprehended have no limits upon their comprehensibility, my statement is banal and barren. The most valuable result of such a conclusion would be to cause in us a tremendous distrust of present day knowledge. Because, to all appearance, we are just standing at the threshold of human history and the generations which will correct us will be much more numerous than those whose knowledge--often with little enough regard,--we ourselves correct. Herr Duehring himself explains the necessity of consciousness, knowledge and perception only becoming apparent in a collection of separate individuals. We can only apply the word sovereignty to the thought of these individuals in so far as we do not know of any force which can defeat thought. But we all know that there is no significance to nor power of interpretation of the sovereign power of the knowledge of the thought of each individual, and, according to our experience, there is much more that requires improvement and correction in it than not.
In other words, the sovereignty of thought is realised in a number of highly unsovereign men capable of thinking, the knowledge which has unlimited pretensions to truth is realised in a number of relative blunders; neither the one nor the other can be fully realised except through an endless eternity of human existence. We have here again the same contradiction as above between the necessary, as an absolute conceived characteristic of human thought, and its reality in the very limited thinking single individual, a contradiction which can only be solved in the endless progression of the human race, that is endless as far as we are concerned. In this sense human thought is just as sovereign as not--sovereign, and its possibility of knowledge just as unlimited as limited. It is sovereign and unlimited as regards its nature, its significance, its possibilities, its historical end, it is not sovereign and limited with respect to individual expression and its actuality at any particular time. It is just the same with eternal truths. If mankind only operated with eternal truths and with thought which possessed a sovereign significance and unlimited claims to truth, mankind would have arrived at a point where the eternity of thought becomes realised in actuality and possibility. Thus the famous miracle of the enumerated innumerable would be realised.
But what about those truths which are so well established that to doubt them is to be, as it were, crazy? That twice two is four, that the three angles of a triangle are equal to two right angles, that Paris is in France, that a man will die of hunger if he does not receive food, etc.? Do we not perceive then that there are eternal truths, final truths of last instance? Quite so. We can divide the entire field of knowledge in the old-fashioned way into three great divisions. The first includes all the sciences which are concerned with inanimate nature and which can be treated mathematically, more or less--mathematics, astronomy, mechanics, physics and chemistry. If one like to use big words to express simple things, it may be said that certain results of these sciences are eternal truths, final truths of last instance, whence they are called the exact sciences. But all the results are by no means of this character. With the introduction of variable quantities and the extension of the variability to the infinitely small and the infinitely large, mathematics, otherwise erect, meets with its fall, it has eaten of the apple of knowledge and there has been opened up to it the path of limitless progress as well as that of error.
The virgin condition of absolute purity, the undisturbable certainty of all mathematics has vanished forever, a period of controversy has intervened, and we have now arrived at the state of affairs in which most people carry on the operations of multiplication and division not because they really understand what they are engaged in, but from mere belief because the operation has so far always given correct results. Astronomy and mechanics, physics and chemistry are in a still more confused state, and hypotheses crowd one another thick as a swarm of bees. It cannot be otherwise. In physics we investigate the movements of molecules, in chemistry the development of molecules from atoms, and if the theory of light waves should not be correct we have no absolute knowledge that we even see these interesting things. The lapse of time produces a very thin crop of final truths of last instance. In geology we are in a still more embarrassing situation for we are here involved in the study of preceding epochs in which, as a matter of fact, neither we ourselves nor any other human being ever existed. Here there is much labor spent in the harvesting of truths of last instance, and they are a scanty crop withal.
The second division of knowledge is occupied in the investigation of living organisms. In this field the changes and causalities are so complex that not only does the solution of each question bring about the rise of an unlimited number of new questions, but the solution of each of these separate new questions depends upon years, frequently centuries, of investigation, and can then be only partially completed. So that the need of systematic arrangement of the various interrelations continually surrounds the final truths of the last instance with a prolific and spreading growth of hypotheses. Look at the long succession of progressive steps from Galen to Malpighi necessary to establish correctly so simple a thing as the circulation of the blood of mammals, yet how little we know of the origin of blood corpuscles and how many mistakes we make in, for example, rationally connecting the symptoms and cause of a disease. Besides there are frequently discoveries like those of the cell which compel us to entirely revise all hitherto firmly established truth of the last instance in biology, and to lay numbers of such truths aside for good and all. He who would therefore in this science undertake the proclamation of absolute and immutable truths must be content with such platitudes as the following: "All men must die; all female mammals have mammary glands, etc." He will not even be able to say that the greater animals digest their food by means of the stomach and bowels and not with the head because the centralised system of nerves in the head is not adapted to digestion.
But things are worse with regard to final truths of last instance in the third group of sciences--the historical. These are concerned with the conditions of human life, social conditions, forms of law and the state with their idealistic superstructure of philosophy, religion, art, etc., in their historic succession and in their present day manifestations. In organic nature we have at least to do with a succession of regular phenomena which regularly repeat themselves as far as our immediate observation goes, within very wide limits. Organic species have remained on the whole unaltered since the time of Aristotle. In social history, on the other hand, repetitions of conditions are the exception, not the rule, directly we leave behind the prehistoric conditions of humanity, the stone-age, so-called. Where such repetitions do occur, moreover, they never recur under precisely similar conditions, as for example the occurrence of early tribal communism among all peoples anterior to civilisation and the form of its break up. As regards human history, then, as far as science is concerned, we are at a greater disadvantage than in biology. Furthermore, when the intimate relations existing between a social and political phenomenon come to be recognised it is not, as a rule, perceived until the conditions are actually on the way to decay. Knowledge is therefore entirely relative, since it is limited to a given people and a given epoch, and their nature under transitory social and political forms, when it examines relations and forms conclusions. He who therefore is after final truths of last instance, pure and immutable, will only manage to catch flat phrases and the most arrant commonplaces, like these--man cannot, generally speaking, live without working; up to the present men have for the most part been divided into masters and servants; Napoleon died on May 5th, 1821, and things of that sort.
It is worth noting that in this department of knowledge pretended final truths of last instance are met with most frequently. Only the person who wishes to show that there are eternal truth, eternal morality, and eternal justice in human history, and that these are similar in scope and application to those of mathematics, will proclaim that twice two is four and that birds have beaks and the like to be eternal truths. We can also certainly rely upon the same friend of humanity taking the opportunity to explain that all former inventors of eternal truths have been more or less asses or charlatans, that they have been circumscribed by error and have made mistakes. The fact of their error, however, is natural and proves the existence of the truth, and that it can be reached, and the newly arisen prophet has a ready-to-hand stock of final truths of last instance, eternal law and eternal justice. This has happened hundreds, nay, thousands of times, so that it is a wonder that men are still sufficiently credulous to believe it not only of others, but even of themselves. Here we find a prophet clad in the armour of righteousness who proclaims in the old-fashioned way that whoever else may deny there is still one left to declare final truths of last instance. Denial, nay, doubt even, is a weakness, barren confusion, mole-like scepticism, worse than blank nihilism, confusion worse confounded and other little amiabilities of this sort. As with all prophets, there is no scientific investigation, but merely off-hand condemnation.
We might have made mention of the sciences which investigate the laws of human thought, logic and dialectics. Here we are, however, no better off as regards eternal truths. Herr Duehring explains that the dialectic proper is pure nonsense, and the many books which have been and are still being written on logic prove clearly that final truths of last instance are more sparsely distributed than many believe. Moreover, we are not at all alarmed because the step of science upon which we to-day stand is not a bit more final than any of the preceding steps. Already it includes an immense amount of material for investigation and offers a great chance for specialisation and study to anyone who desires to become expert in any particular branch. Whoever expects to find final and immutable truths in observations which in the very nature of things must remain relative for successive generations, and can only be completed piecemeal, as in cosmogony, geology and human history, which must always be incomplete owing to the complexity of the historical material, shows perverse ignorance even where he does not, as in the present case, set up claims of personal infallibility.
Truth and error, like all such mutually antagonistic concepts, have only an absolute reality under very limited conditions, as we have seen, and as even Herr Duehring should know by a slight acquaintance with the first elements of dialectics, which show the insufficiency of all polar antagonisms. As soon as we bring the antagonism of truth and error out of this limited field it becomes relative and is not serviceable for new scientific statements. If we should seek to establish its reality beyond those limits we are at once confronted by a dilemma, both poles of the antagonism come into conflict with their opposite; truth becomes error and error becomes truth. Let us take, for example, the well-known Boyle's law, according to which, the temperature remaining the same, the volume of the gas varies as the pressure to which it is subjected. Regnault discovered that this law does not apply in certain cases. If he had been a realist-philosopher he would have been obliged to say, "Boyle's law is mutable, therefore it does not possess absolute truth, therefore it is untrue, therefore it is false."
He would thus have made a greater error than that which was latent in Boyle's law, his little particle of truth would have been drowned in a flood of error; he would in this way have elaborated his correct result into an error compared with which Boyle's law with its particle of error fastened to it would have appeared as the truth. Regnault, scientist as he was, did not trouble himself with such childish performances. He investigated further and found that Boyle's law is only approximately correct, having no validity in the case of gases which can be made liquid by pressure when the pressure approaches the point where liquefaction sets in. Boyle's law therefore is shown only to be true within specific bounds. But is it absolute, a final truth of last instance within specific bounds? No physicist would say so. He would say that it is correct for certain gases and within certain limits of pressure and temperature, and even then within these somewhat narrow limits he would not exclude the possibility of a still narrower limitation or change in application as the result of further investigation. This is how final truths of last instance stand in physics, for example. Really scientific works as a rule avoid such dogmatic expressions as truth and error, but they are constantly cropping up in works like the Philosophy of Reality, where mere loose talking vaunts itself the supreme result of sovereign thought.
But a naive reader may say, "Where has Herr Duehring expressly stated that the content of his philosophy of reality is final truth of the last instance?" Well, for example, in his dithyramb on his system which we quoted above, and again where he says "Moral truths as far as they are known are as sound as those of mathematics." Does not Herr Duehring explain that by reason of his powers of criticism and searching investigations, the fundamental philosophy has been brought to light and that he has thus bestowed upon us final truths of last instance? But if Herr Duehring does not set up such a claim either on his own behalf or that of his time, if he says that some time in the misty future final truths of last instance will be established, and that therefore his own statements are merely accidental and confused, a kind of "mole-like scepticism" and "barren confusion," what is all the fuss about, and what useful purpose is served by Herr Duehring?
If we gain no ground in the matter of truth and error we gain less in respect of good and evil. Here we have an antagonism of ethical significance, and ethics is a department of human history in which final truths are but slight and few. From people to people, from age to age, there have been such changes in the ideas of good and evil that these concepts are contradictory in different periods and among different peoples. But some one may remark, "Good is still not evil and evil is not good; if good and evil are confused all morality is abolished, and each may do what he will." When the rhetoric is stripped away this is the opinion of Herr Duehring. But the matter is not to be disposed of so easily. If things were as easy as that there would be no dispute about good and evil. Everybody would know what was good and what was evil. How is it to-day, however? What system of ethics is preached to us to-day? There is first the Christian-feudal, a survival of the early days of faith, which is as a matter of fact subdivided into Catholic and Protestant, of which there are still further subdivisions, from the Jesuit-Catholic and orthodox Protestant to loosely drawn ethical systems. There figure also the modern or bourgeois, and still further the proletarian future system of morality, so that the progressive European countries alone present three contemporaneous and coexistent actual theories of ethics. Which is the true one? No single one of them, regarded as a finality, but that system assuredly possesses the most elements of truth which promises the longest duration, which existent in the present is also involved in the revolution of the future, the proletarian.
But if we now see that the three classes of modern society, the feudal aristocracy, the bourgeoisie and the proletarian, have their distinctive ethical systems, we can only conclude therefrom that mankind consciously or unconsciously shapes its moral views in accordance with the material facts upon which in the last instance the class existence is based--upon the economic conditions under which production and exchange are carried on. But in the three above mentioned systems of ethics there is much which is common to all three of them, and might not this at least constitute a portion of an eternally stable system of ethics? These ethical theories pass through three distinct steps in their historical development, they have therefore a common historical basis and hence necessarily much in common. Further, for approximately similar economic stages there must, necessarily be a coincidence of similar stages of economic development, and ethical theories must of necessity coincide with a greater or less degree of closeness. From the very moment when private property in movables developed there had to be ethical sanctions of general effect in all communities in which private property prevailed, thus: Thou shalt not steal. Is this commandment, then, an eternal commandment? By no means. In a society in which the motive for theft did not exist stealing would only be the practice of the weak-minded, and the preacher of morals who proclaimed "Thou shalt not steal" as an eternal commandment would only be laughed at for his pains.
We here call attention to the attempt to force a sort of moral dogmatism upon us as eternal, final, immutable moral law, upon the pretext that the moral law is possessed of fixed principles which transcend history and the variations of individual peoples. We state, on the contrary, that up to the present time all ethical theory is in the last instance a testimony to the existence of certain economic conditions prevailing in any community at any particular time. And in proportion as society developed class-antagonisms, morality became a class morality and either justified the interests and domination of the ruling class, or as soon as a subject class became strong enough justified revolt against the domination of the ruling class and the interests of the subject class. That, by this means, there is an advance made in morals as a whole, just as there is in all other branches of human knowledge, there can be no doubt. But we have not yet advanced beyond class morals. Real human morality superior to class morality and its traditions will not be possible until a stage in human history has been reached in which class antagonisms have not only been overcome but have been forgotten as regards the conduct of life. Now the colossal egotism of Herr Duehring may be understood when it is seen that, on the eve of a revolution which will bring about a state of society devoid of classes, he claims from the midst of an old and class divided society to proclaim an eternal system of morals independent of time and material change. He himself declares what up to the present has been hid from the rest of us that he understands the structure of this future society at least as regards its salient features.
