Much of the work is valueless to-day because of Engels' eagerness to score a point off his adversary rather than to state his own case. But where the philosopher lays the controversialist on one side for a brief period, and takes the trouble to elucidate his own ideas we discover what has been lost by these defects of temperament. He possesses in a marked degree the gift of clear analysis and of keen and subtle statement.
The socialist movement everywhere arrives some time or other at what may be called the Duehring stage of controversy. There are two very distinct impulses towards socialism. The individuals who are influenced by these impulses must sooner or later come into collision, and as a result of the impact the movement is for a time divided into hostile parties and a war of pamphleteering and oratory supervenes. This period has just ended in France. For the last few years the French movement has been divided upon the question of the philosophical foundation of the movement, and the parties to the controversy may be divided into those who sought to justify the movement upon ethical grounds and those who have regarded it as a modern political phenomenon dependent alone upon economic conditions. The former of these parties based its claims to the suffrages of the French people upon the justice of the socialistic demands. It proclaimed socialism to be the logical result of the Revolution, the necessary conclusion from the teachings of the revolutionary philosophers. Justice was the word in which they summed up the claims of socialism, that and Equality, for which latter term as Engels points out in the present work, the French have a fondness which amounts almost to a mania. Hence one party of the French socialist movement chose as a platform those very "eternal truths" which Engels ridicules and which it is the sole purpose of the present work to attack.
To kill "eternal truths" is however by no means an easy matter. Years of habit have made them part of the mental structure of the citizens of the modern democratic or semi-democratic states. Not only in France but to an even greater degree in the English speaking countries these "eternal truths" persist, they form the stock in trade of the clergyman and the ordinary politician. Bernard Shaw directs the shafts of his ridicule against these "eternal truths" and smites with a sarcasm which is more fatal than all the solemn German philosophy which Engels has at his command. But Shaw is not appreciated by the British socialist. The latter cannot imagine that the writer is really poking fun at things so exceedingly serious and so essential to any well constituted man, to a well-constituted Briton in particular. The British socialist is as much in love with "eternal truths" as is the stiffest and most unregenerate of his bourgeois opponents. He therefore toploftily declares that Mr. Shaw is an unbalanced person, a licensed jester. Precisely the same results would attend the efforts of an American iconoclast who would venture to ridicule the "eternal truths" which have been handed down to us in documents of unimpeachable respectability, like the Declaration of Independence, and by Fourth of July orators, portly of person and of phrase.
The "eternal truth" phase of socialist controversy seems to be as eternal as the truth, and must necessarily be so as long as the movement is recruited by men who bring into it the ideas which they have derived from the ordinary training of the American citizen.
The other side of the controversy to which reference has been made derived its philosophy from the experience of the proletariat. This modern proletariat, trained to, the machine, is a distinct product of the occupation by which it lives. The organisation of industry in the grasp of which the workman is held during all his working hours and manufacture by the machine-process, the motions of which he is compelled to follow have produced in him a mental condition which does not readily respond to any sentimental stimulus. The incessant process from cause to effect endows him with a sort of logical sense in accordance with which he works out the problems of life independent of the preconceptions and prejudices which have so great a hold upon the reason of his fellow citizens who are not of the industrial proletariat. Without knowing why he arrives by dint of the experience of his daily toil at the same conclusions as Engels attained as the result of philosophic training and much erudition. The Church is well aware of this fact to her sorrow for the industrial proletarian seldom darkens her portals. He has no hatred of religion, as the atheistic radical bourgeois had, but with a good-natured "non possumus" says by his actions what Engels says by his philosophy.
Revolution is an every day occurrence with the industrial proletarian. He sees processes transformed in the twinkling of an eye. He wakes up one morning to find that the trade which he has learned laboriously has overnight become a drug on the market. He is used to seeing the machine whose energy has enchained him flung on the scrap heap and contemptuously disowned, in favor of a more competent successor whose motions he must learn to follow or be himself flung on the scrap heap also. This constant revolution in the industrial process enters into his blood. He becomes a revolutionist by force of habit. There is no need to preach the dialectic to him. It is continually preached. The transitoriness of phenomena is impressed upon him by the changes in industrial combinations, by the constant substitution of new modes of production for those to which he has been accustomed, substitutions which may make "an aristocrat of labor" of him to-day, and send him tramping to-morrow.
The industrial proletarian therefore knows practically what Engels has taught philosophically. So that when in the course of his political peregrinations he strays into the socialist movement and there finds those who profess a socialism based upon abstract conceptions and "eternal truths" his contempt is as outspoken as that of a Friedrich Engels who chances upon a certain Eugen Duehring spouting paraphrases of Rousseau by the socialistic wayside. Engels simply anticipated by the way of books the point of view reached by the industrial proletarian of to-day by the way of experience, and by the American machine-made proletarian in particular. This is a matter of no mean importance. In the following pages we can detect if we can look beyond and beneath the mere criticism of Duehring, an attitude of mind, not of one controversialist to another merely but of an entire class, the class upon which modern society is driven more and more to rely, to the class which relies upon it.
For their popular support classes and governments rely upon formulæ. When the cry of "Down with the Tsar" takes the place of the humbly spoken "Little Father" what becomes of the Tsardom? When the terms "Liberty" and "Equality" become the jest of the workshop, upon what basis can a modern democratic state depend? This criticism of "eternal truths" is destructive criticism, and destructive of much more than the "truths." It is more destructive than sedition itself. Sedition may be suppressed cheaply in these days of quick-firing guns and open streets. But society crumbles away almost insensibly beneath the mordant acid of contemptuous analysis. So to-day goaded on the one side by the gibes of the machine-made proletariat, and on the other, by the raillery of the philosophic jester, society staggers along like a wounded giant and is only too glad to creep into its cave and to forget its sorrows in drink.
As for 1875, "Many things have happened since then" as Beaconsfield used to say, but of all that has happened nothing could have given more cynical pleasure to the "Old Jew" than the lack of faith in its own shibboleths which has seized the cocksure pompous society in which he disported himself. The rhetoric of a Gladstone based upon the "eternal truths" which constituted always the foundations of his political appeals would fail to affect the masses to-day with any other feeling than that of ridicule. We have already arrived at the "Twilight of the Idols" at least so far as "eternal truths" are concerned. They still find however an insecure roosting place in the pulpits of the protestant sects.
If blows have been showered upon the political "eternal truths" in the name of which the present epoch came into existence social and ethical ideals have by no means escaped attack. Revolt has been the watchword of artist and theologian alike. The pre-Rafaelite school, a not altogether unworthy child of the Chartist movement, raised the cry of artistic revolt against absolutism and the revolt spread in ever widening circles until it has exhausted itself in the sickly egotism of the "art nouveau." Even Engels, with all his independence and glorification of change as a philosophy, can find an opportunity to fling a sneer at Wagner and the "music of the future." The remnants of early Victorianism cling persistently to Engels. He cannot release
