The Natural Science Note-Books Of Marx And Engels: Middle Of 1877 – Early 1883

Somnath Ghosh (AM-18210) and Pradip Baksi

It is customary to associate the names of Marx and Engels with the
emergence of scientific socialism in the 19thcentury Europe. Students of
socialist literature also associate the name of Engels with the study of
natural sciences of the last century, from within the socialist movement.
However, the natural science studies of Karl Marx remain relatively
unknown. The present communication announces the publication of the 31st
Volume of Section IV of the MEGA (Marx-Engels-Gesammtausgabe; Complete
Works of Marx-Engels)1, on the 16th of December, 1999.2 This volume
contains Marx’s notes and excerpts on Inorganic and Organic Chemistry and
Electricity. Together with Engels’ excerpts and notes on parts of Physics
and Ecology, related to his Dialectics of Nature . The present volume is of
interest to the students of history of the 19th century on many counts : it
provides new source materials for the study of the interrelationships of
the history of natural and social sciences of that century, for
Marx-studies and Engels-studies and, through these, for the study of the
interrelationships of the sciences and the socialist movement.

Before we proceed with the contents of MEGA IV/31, a few words about the
MEGA itself are in order3. Some 27 years after the death of Marx and, 15
years after the death of Engels, in the year1910, the plan for publishing
the Complete Works of Marx and Engels, in the original languages of their
texts, was discussed for the first time, at a meeting of some prominent
Austro-Marxists, who, however, could not start the project. David
Borisovich Rjazanov (Goldendach) (1870 –1938), an émigré Russian
revolutionary intellectual, present at that meeting began to realize this
plan, with active support from Lenin and the Comintern, in the 1920’s from
Moskow, Frankfurt-am-Main and, Berlin. At that time the Marx-Engels
archives were the property of the Social Democratic Party of Germany (SPD).
They permitted the Russians to photo-copy the Marx-Engels papers. Thus
began the first historical attempt to publish the MEGA. Subsequently, as
the relations between the SPD and Rjanozov’s sponsors – the Comintern--
soured, the SPD leadership cancelled the arrangement, and the fate of MEGA
was sealed. Events followed in quick succession: in Russia Rjazanov was
removed from his responsibility; in Germany the Nazis came to power in
1933; the publication of MEGA came to a halt in 19354. In the face of the
lawlessness of the Nazi regime, a large part of the SPD archives, including
the Marx-Engels papers, were taken out of Germany. Subsequently, these
papers were sold to a Dutch insurance company, which in turn gave them to
the newly established Internationaal Instituut voor Sociale Geschiedenis
(IISG), at Amsterdam, in 1938. Some more papers were collected at Moscow,
both before and after the second world war. As of now some 2/3 of the
Marx-Engels papers are being preserved at the aforementioned institute at
Amsterdam and, about 1/3 of them are being preserved at two Russian
centres5, which grew out of the now defunct Institute of Marxism-Leninism
of Moscow.

In the 1960’s a new attempt to publish the MEGA was made by the Institutes
of Marxism-Leninism (IML) of Berlin and Moscow. The IISG, permitted the
IMLs to use the documents preserved at Amsterdam, but did not participate
in the project. This attempt is now called MEGA(2) and, the earlier attempt
is called MEGA(1). The Karl-Marx-House (KMH) of Trier in Germany also
maintained close contact with the project.

In 1989, the fast unfolding political changes in GDR and USSR created
uncertainities for the future of MEGA(2). IISG and KMH changed their
earlier stand and, agreed to participate in the project, to ensure its
further continuation. In the autumn of 1990, the
International-Marx-Engels-Stiftung (IMES; International Marx-Engels
Foundation) was established, with its office at IISG, Amsterdam, with the
sole purpose of completing the MEGA(2). By that time, 43 volumes or parts
thereof of the MEGA(2) were already published; work was in progress on 7
more volumes or parts thereof. These volumes were published by 1993. A new
editorial policy was formulated in 19926. Since 1994 the IMES is publishing
its house journal the MEGA-Studien7 .It has been decided that under the new
management, MEGA(2)will be completed in 114 volumes, grouped into the
following 4 divisions : Division I – all the works, articles and drafts,
other than those related to the Capital (32 volumes); Division II – the
Capital and the work preparatory to it (15 volumes, many containing several
parts); Division III – Correspondence(35 volumes);and Division IV –
excerpts , notes and marginalia (32 volumes). The Akademie Verlag of
Berlin8 are the current publishers of the MEGA(2).

At present 11 teams are working on the different yet-to-be-published
volumes of the MEGA(2), in Denmark, France, Germany, Japan, the
Netherlands, Russia and the USA. The first volume under the new management
came out in December 19989. Two more volumes have been published in 199910.

So far, some of Marx’s excerpts and notes on Geology, Agro-Chemistry and
Soil Science have been published in MEGA IV/ 6, 8 and 9. Elsewhere, parts
of his Mathematical Manuscripts have also been published11. A vast amount
of his notes and excerpts on these disciplines and, on Physics, Technology,
Agriculture, Geology and Physiology, still remain unpublished12.

The recently published MEGA IV/31 consists of two parts : Texts and,
Text-critical Apparatus. The Text portion is subdivided into two sections.
The first section contains Marx’s excerpts and notes on Inorganic and
Organic Chemistry and, Electricity. The second section consists of Engels
excerpts and notes on parts of Physics and Ecology. The Text-Critical
Apparatus contains a general introduction; introductions to the subsections
of the texts; The inventories of variant readings, corrections and
comments, which everywhere indicate the corresponding page and line number
of the text ; name index; indexes of literature used in the apparatus; and
a subject index. The technical standards of editing and production are
veritable examples for other editors and publishers of similar works to
follow. The introductions in the apparatus portion provide valuable
historical data related to the topics of the texts; these may help the
reader situate the texts in the history of the corresponding disciplines
and, appreciate the specificity of the interests shown by Marx and Engels
in the study of these sciences.

Marx’s excerpts and notes on Chemistry, pertaining to the period 1877
–1883, are distributed in 6 different notebooks. They appear in this volume
as :

Serial No.      Title                                   Marx’s Chemistry Notebook No.
1.              On the Atomic Theory                                    [1]

For these excerpts Marx used some earlier and contemporary literature on
Chemistry, as well as some literature of the related sciences, like
Physics, Geology and Physiology. The sources used by him are :

9. Joseph Beete Jukes , The Student’s Manual of Geology. 3rd. ed. Edinburgh
1872 The selection of sources mirrors Marx’s interest in Inorganic,
Organic, Physical ,Physiological and Geological Chemistry. As a rule Marx
worked with many sources on a single topic.

The excerpts titled ‘ On the Atomic Theory’ – his notebook [1] – contain a
discussion of the : (1) atomistic principle as propounded by John Dalton
(1766–1844), (2) related stoichiometric laws of chemical combination of
elements and, (3) determination of atomic and molecular weights of elements
and compounds – wherein the doctrine of Joseph Louis Gay-Lussac (1778–1850)
and, the principle of Lorenzo Romano Amadeo Carlo comte di Quaregna e
Ceretto Avogadro (1776 -1856), together with the follow up corollaries like
the relation between ‘vapour density’ and ‘molecular weight’, have been
discussed with various illustrations.

The repeatedly excerpted tables of Inorganic and Organic Chemistry – in his
notebooks [2] – [6]-- contain tables for Non-metals and Metals ; the
Periodic System of Julius Lothar Meyer (1830-1895); discussion of
Quantitative Valency, Oxides, Hydroxides, Acids and Salts; tables of the
various groups of Organic compounds, like the Paraffins, Carbohydrates,
Aromatic Compounds, alkaloids, Uric Acid and related substances, Carbonyl
and Sulfocarbonyl Compounds, Etheric and Anhydride substances, Ammonia and
its derivatives, Organic Acids etc.

Marx’s chemistry-excerpts are followed by his excerpts from : Edouard
Hospitalier, La physique moderne. Les principales applications de
l’electricite 2.ed. ( Modern Physics.The Principal Applications of
Electricity . 2nd ed. ) Paris 1882. It contains discussions on : (1) the
sources of electricity, like the ‘Vol taic Piles’ or ‘Galvanic Batteries’ ;
the physical nature of their functioning; (2) the characteristics of
current electricity – Ohm’s Law and related issues; and (3) lists the units
for measuring Electrical Current, Voltage, Resistance etc. The first
section of MEGA IV/31 comes to an end with these excerpts.

The second section of the volume contains Engels’ excerpts from :

1. William Thomson, Peter Guthrie Tait, Treatise on Natural Philosophy.
Vol.1. Oxford 1867.

2.  Carl Fraas, Klima und Pflanzenwelt in der Zeit, ein Beitrag zur
Geschichte beider . ( Climate and Plant World in Time, a contribution to
the History of Both ). Landshut 1847.

3. Hermann Helmholtz , Ueber die Erhaltung der Kraft, eine physikalische
Abhandlung, vorgetragen in der physikalschen Gescselschaft zui Berlin am
23. Juli 1847 ( On the Conservation of Force, a physical treatise,
presented at the meeting of the Physical Society at Berlin on the 23rd of
July 1847). Berlin 1847.

4.  Jean Baptiste Le Rond d’Alembert, Traite de dynamique ….. (Treatise on
Dynamics …….) Paris 1743.

5.  Gustav Wiedemann, Die Lehre vom Galvanismus und Electromagnetismus (
The Doctrine of Galvanism and Electromagnetism ). 2. neubearb. und verm.
Aufl. Bd. 1.2 (2nd revised and augmented ed. Vol.1.2 ). Braunschweig 1874.

6.  A note on Heat.

7.  A note on the Units of Measuring Electricity.

Engels made use of these excerpts and notes in several articles of the
Dialectics of Nature13 -- titled ‘The Measure of Motion --Work’, ‘ Tidal
Friction. Kant and Thomson - Tait’. ‘ The Share of Labour in the Apes
becoming Human Beings’ ( Anteil der Arbeit an der Menschwerdung des Affen’
: usually rendered in English as ‘The Part Played by Labour in Transition
from Ape to Man’), ‘Electricity’, and ‘Heat’.

In view of the fact that Engels’ study of the natural sciences has received
the attention of interested scholars for quite some time14, in the
remaining part of the present paper we shall concentrate on Marx’s natural
science studies.

Marx’s interest in Chemistry coincides with the period of his intense
preoccupation with political economy. Since the 1850s he noticed that there
are connections among : ground rent, soil fertility, use of fertilizers in
agriculture, plant nutrients and, changes in the science of Chemistry15. He
studied some of the works of James Finlay Weir Jhonston (1796 –1855)16 ,
Justus Freiherr von Liebig (1803--1873) 17;

Attended the lectures on modern chemistry delivered by the Director of
Royal College of Chemistry at London, August Wilhelm von Hofmann (1818-
!892) 18. He was also aware of some of the works of Christian Friedrich
Schonbein (1799 –1868) 19, Auguste Laurent (1807–1853) 20 , Charles
Fre/de/rick Gerhardt (1816 –1856) 21, Charles Adolphe Wurtz (1817 – 1884)
22 , and , Friedrich August Kekule/ von Stardonitz (1829 –1896) 23. His
friend Carl Schorlemmer (1834–1892) – a student of Robert Wilhelm Bunsen
(1811–1899), Heinrich Will (1812–1890) and Hermann Kopp (1817–1892) –
greatly influenced his study of Chemistry.

The then developments in Chemistry were governed by the introduction of
atomic and molecular theories, the theories of structure and bonds and, the
periodic systems. Marx’s extracts and notes on Chemistry partly mirror
these developments. In the case of periodic system, it appears that Marx
was acquainted with the work of Julius Lothar Meyer (1830 –1895), but not
with that of Dimitry Ivanovich Mendeleev (1834 –1907).

Marx’s interest in electricity also dates back at least to the 1850s. In
July 1850 Marx observed that steam was going to be superseded by
electricity as the source of energy for industrial technology24 In May 1851
he discussed with Engels and Daniels the possibility of use of electricity
in agriculture 25, in the light of an article published earlier in The
Economist 26. The excerpts from Hospitalier’s book indicate a rekindling of
his interests in the progress of theoretical and practical knowledge about
electricity.

MEGA IV/31, thus documents only a phase and some aspects of Marx’s
intensive pre-occupation with the natural sciences. Students of history of
science, and of socialism in the 19th century,eagerly

Await the publication of his notes and excerpts on Physics, History of
Technology, Geology, Soil Science, History of Agricultural
Plants,,Agricultural Chemistry, Physiology of Plants, of Animals and of
Human Beings, parts of Mathematics and, on the interrelationships of the
Natural Sciences and Philosophy27.

The editorial work on MEGA IV/31 began in GDR, after the publication of
MEGA I/26, in 1985. It continued within a decaying East German state, under
conditions of managerial incompetence, staff reduction, underpayment, and
political perfidy. After the unification of Germany and, take over of the

MEGA by a new management, the entire work had to be comprehensively revised
according to the stipulations prescribed in the new rules for editing (see
: n.2 above). But never mind, as they say in Persian: Der aayad, durust
aayad ( It came late, but it has been delivered well) !
