If, as seems likely, einstein only saw the essay on electricity, his hesitation can easily be understood, since this deals almost wholly with questions which now seem remote. The manuscript was first edited by riazanov, and printed in 1927. However, Adoratski's edition of 1935 is more satisfactory, as several passages which made nonsense in the earlier edition have now been deciphered. Had Engels' method of thinking been more familiar, the transformations of our ideas on physics which have occurred during the last thirty years would have been smoother. Had his remarks on Darwinism been generally known, i for one would have been saved a certain amount of muddled thinking. I therefore welcome wholeheartedly the publication of an English translation of dialectics of Nature, and hope that future generations of scientists will find that it helps them to elasticity of thought. But it must not be thought that dialectics of Nature is only of interest to scientists.
A socratic Perspective on the
He was well aware that he was not infallible, and that the labour movement wants no popes or inspired scriptures. The condition of the working Class in England in 1844, of which an English translation had been published in America in 1885, was first published in England in 1892. In his preface written after forty-eight years he says: "I have taken great care not to strike out of the text the many prophecies, amongst others that of an imminent social revolution in England, which my youthful ardour induced me to venture upon. The wonder is, not that a good many of them proved wrong, but that so many of them have proved right." I think that readers of dialectics of Nature will come to a similar conclusion. I have not yet mentioned the sections on the history of science. These are among the most brilliant passages in the whole book, but they represent a line of thought which was followed by marx and Engels reviews in many of their books and which has since been developed by others, so most readers will find them less. Finally, there is the delightful essay on "Scientific research into the spirit world." There is a tendency among materialists to neglect the problems here dealt with. It is worthwhile noticing that Engels did not. On the contrary he produced a number of phenomena which were regarded as "occult" and mysterious in his day, and arrived at the same conclusions as most scientific investigators in this field have reached, provided that, like engels, they brought to their work robust common. It was a great misfortune, not only for Marxism, but for all branches of natural science, that Bernstein, into whose hands the manuscript came when Engels died in 1895, did not publish. In 1924 he submitted it (or part of it) to einstein, who, though he did not think it of great interest from for the standpoint of modern physics, was on the whole in favour of publication.
When all such criticisms have from been made, it is astonishing how Engels anticipated the progress of science in the sixty years which have elapsed since he wrote. He certainly did not like the atomic theory of electricity, which held sway from 1900 to 1930, and until it turned out that the electron behaved not only like a particle but like a system of moving waves he might well have been thought. Only in the last four years has it turned out that certain pure proteins do exhibit one of the most essential features of living things, reproducing themselves in a variety of environments. While we can everywhere study Engels' method of thinking with advantage, i believe that the sections of the book which deal with biology are the most immediately valuable to scientists to-day. This may of course be because as a biologist I can detect subtleties of Engels' thought which I have missed in the physical sections. It may be because biology has undergone less spectacular changes than physics in the last two generations. In order to help readers to follow the development of science since Engels' time, i have added some notes. A few readers may object to my pointing out that Engels was occasionally wrong. Engels would not have objected.
Elsewhere there are statements which are certainly untrue, for example in the sections on stars and Protozoa. But here Engels cannot be blamed for following some of the best astronomers and zoologists of his day. The technical improvement of the telescope and microscope has of course led to great increases in our knowledge here in the last sixty years. On the other hand, Engels' remarks on the differential calculus, though inapplicable to that branch of mathematics as now taught, were correct in his own day, and for some time after. He points out that it actually developed by contradiction, and is none the worse for that. To-day "rigorous" proofs are given of many of the theorems to which he refers, and some mathematicians claim to have eliminated the contradictions. Actually they have only pushed the contradictions into the background, where they remain in the field of mathematical logic. Not only has every effort to deduce all mathematics from a set of axioms, and rules for applying them, failed, but Gödel has proved that they must fail. So the fact that the calculus can be taught without involving the particular contradictions mentioned by Engels in no way impugns the validity of his dialectical argument.

In a letter to marx on november 23rd, 1882, he points out that siemens, in his presidential address to the British Association, has defined a new unit, that of electric power, the watt, which is proportional to the resistance multiplied by the square of the. He compares these with the expressions for momentum and energy, discussed in the essay on "The measure of motion - work and points out that in each case we have simple proportionality (momentum as velocity and electromotive force as current) when we are not dealing. But when the energy is transformed into heat or work the correct value is found by squaring the velocity or current. "so it is a general law of motion which I was the first to formulate." we can now see why this. The momentum and the electromotive force, having directions, are reversed when the speed and current are reversed. But the energy remains unaltered. So the speed or the current must come into the formula as the square (or some even power) since (-x).
In the essay on " Tidal friction Engels writing made a serious mistake, or more accurately a mistake which would have been statement serious had he published. But i very much doubt whether he would have done. In the manuscript notes for Anti-dühring, 1 he supported the view, quite commonly held in the nineteenth century, that we find truths such as mathematical axioms self-evident because our ancestors have been convinced of their validity, while they would not appear self-evident to a bushman. Now this view is almost certainly incorrect, and Engels presumably saw the fallacy, and did not have it printed. I have little doubt that either he or one of his scientific friends such as Schorlemmer would have detected the mistake in the essay on "Tidal friction." But even as a mistake it is interesting, because it is one of the mistakes which lead. Such mistakes have been extremely fruitful in the history of science.
But it was still very incompletely realised, and still more incompletely applied. Words such as "force "motion and " vis viva " were used where we should now speak of energy. The essays on "Basic forms of motion "The measure of motion - work and "Heat" are largely concerned with the controversies which arose from incomplete or faulty theories about energy. They are interesting as showing how ideas on this subject developed, and how Engels tackled the controversies of his day. However many of these controversies are now settled. The expression vis viva is no longer used for double the kinetic energy, and "force" has acquired a definite meaning in physics.
Engels would not have published them in their present form, if only because, in the later essay on tidal friction, he uses a more modern terminology. Their interest lies not so much in their detailed criticism of theories, many of which have ceased to be of importance, but in showing how Engels grappled with intellectual problems. The essay on electricity "dates" even more. As a criticism of wiedemann's inconsistencies it is interesting, and it ends with a plea for a closer investigation of the connection between chemical and electrical action, which, as Engels said, "will lead to important results in both spheres of investigation." This prophecy has,. Arrhenius' ionic theory has transformed chemistry, and Thomson's electron theory has revolutionised physics. Here again, the manuscript would certainly have been revised before publication.

Part of the manuscript is ready for publication, though, as we shall see, it would almost certainly have been revised. Much of it merely consists of rough notes, which Engels hoped to work up later. They are often hard to read, and full of abbreviations,. For magnet and magnetism. There are occasional scribbles and sketches in the margin. Finally, although the bulk of the manuscript is in German, Engels thought equally well in English and French, and occasionally produced a hybrid sentence, such as "Wenn coulomb von particles of electricity spricht, which repel each other inversely as the square of the distance,. Most of the manuscript seems to have been written between 18, that degenerative is to say it refers to the science of sixty years ago. Hence it is often hard to follow if one does not know the history of the scientific practice and theory of that time. The idea of what is now called the conservation of energy was beginning to permeate physics, chemistry, and biology.
In 1871 he came to london, and started reading scientific books and journals on a large scale. He intended to write a great book to show "that in nature the same dialectical laws of movement are carried out in the confusion of its countless changes, as also govern the apparent contingency of events in history." If this book had been written,. But apart from political work, other intellectual tasks lay before Engels. Dühring had to be answered, and perhaps, anti-dühring, which covers the whole field of human knowledge, is a greater book than. Dialectics of Nature would have been had Engels completed. After Marx's death in 1883 he had the gigantic task of editing and completing. Capital, besides which he wrote, feuerbach and, the Origin of the family. So dialectics of Nature was never finished. The manuscript consists of four book bundles, all in Engels' handwriting, save for a number of"tions from Greek philosophers in that of Marx.
and Becquerel, whose discoveries could be interpreted from a materialistic or an idealistic point of view. However, lenin did not attempt to cover the whole of science. He was mainly concerned with the revolution in physics which was then in progress, and had little to say on astronomy, geology, chemistry, or biology. But thirty years before lenin, Engels had tried to discuss the whole of science from. He had always been a student of science. Since 1861 he had been in close touch with the chemist Schorlemmer at Manchester, and had discussed scientific problems with him and Marx for many years.
That is to say from it can be applied to problems of "pure" science as well as to the social relations of science. Scientists are becoming familiar with the application of Marxist ideas to the place of science in society. Some accept it in whole or in part, others fight against it vigorously, and say that they are pursuing pure knowledge for its own sake. But many of them are unaware that Marxism has any bearing on scientific problems considered out of their relation to society, for example to the problems of tautomerism in chemistry or individuality in biology. And certain Marxists are inclined to regard the study of such scientific and philosophical problems as unimportant. Yet they have before them the example of Lenin. In 1905 the russian. It was necessary to build up the revolutionary movement afresh.

1883-dialectics of front Nature-Preface, j aldane 1939, engels' dialectics of Nature. Marxism has a two-fold bearing on science. In the first place marxists study science among other human activities. They show how the scientific activities of any society depend on its changing needs, and so in the long run on its productive methods, and how science changes the productive methods, and therefore the whole society. This analysis is needed for any scientific approach to history, and even non-Marxists are now accepting parts. But secondly marx and Engels were not content to analyse the changes in society. In dialectics they saw the science of the general laws of change, not only in society and in human thought, but in the external world which is mirrored by human thought.
