Marx’s Logic


From the series Principles of Marxism


The method of exposition in Marx’s economic analysis, which he summarised on various occasions, adopts the progression from the simplest to the most complex concepts. It is a method that, at first glance, appears to correspond to common sense — from easy to difficult — but which Marx explains by contradicting common sense. Common sense distorts knowledge, starting right from the elementary building blocks of the representation of reality, which requires scientific abstraction to understand. Opportunism will always set the prejudices of common sense against the science-party.

Marx writes, introducing Volume I of Capital: “The value-form, whose fully developed shape is the money-form, is very elementary and simple. Nevertheless, the human mind has for more than 2,000 years sought in vain to get to the bottom of it, whilst on the other hand, to the successful analysis of much more composite and complex forms, there has been at least an approximation. Why? Because the body, as an organic whole, is easier of study than are the cells of that body. In the analysis of economic forms, moreover, neither microscopes nor chemical reagents are of use. The force of abstraction must replace both. But in bourgeois society the commodity-form of the product of labour — the value-form of the commodity — is the economic cell form. To the superficial observer, the analysis of these forms seems to turn upon minutiae. It does in fact deal with minutiae, but they are of the same order as those dealt with in microscopic anatomy".

Volume I of Capital, Marx adds, “cannot stand accused on the score of difficulty”, “with the exception of the section on value-form”.

The microscopic anatomy of the cell of capital, the commodity, dissected with the scalpel of scientific abstraction, is formidably powerful. It is the foundation for understanding the mysteries of capital. We are surrounded by immense quantities of commodities of all shapes and uses. Consumer goods; raw materials; energy consumed in homes, offices, and factories; means of production; housing; industrial warehouses; land; means of transport; tourist travel; health care; these are all commodities. Capitalism appears as an endless fair of commodities that are constantly modified, modernised, and spread throughout every community on the planet. Everyone knows that each commodity is characterised by its specific utility, its use-value, and by its price. The price tells us that the use-value is the shell, the casket that contains an exchange-value. On the market, the buyer is looking for a particular use-value; the seller is interested in realising the exchange-value contained in the commodity he sells.

The price makes it possible to compare even the most disparate goods. For example, it can be said that a pair of shoes is worth as much as two shirts. Shoes and shirts are both products of labour. The exchange-value expresses the quantity of labour contained in each commodity, that is, the labour-time employed in its production. However, it is not a question of just any quantity of labour-time, but of socially necessary labour-time, meaning labour-time under the average prevailing social conditions, with respect to skills, technique, productivity, and contractual relations. The analysis proceeds in small steps in its run-up before taking the big leap. It dwells on labour to identify its links with value. In the commodity, we see two aspects of the labour that produced it: in every commodity there is an expenditure of labour-power, of capacity to work that we call abstract labour, because it is necessary for any type of productive activity. There is also a specific activity and labour skill, a concrete labour that gives form and functionality to the commodity. Concrete labour gives the commodity its use-value, abstract labour gives it its exchange-value.

The process in which Marx breaks down the commodity, by scientific abstraction, into its most intimate connections is vital because it contains the solution to the enigma of capital. When the capitalist, holder of the money-commodity, and the proletarian, holder of only his labour-power commodity, or his capacity to work, meet in the sphere of circulation, under certain historical conditions, an exchange takes place. The capitalist acquires the commodity labour-power by buying it at its exchange-value, consisting of the means of subsistence necessary for its production and reproduction: an exchange which, in the field of circulation, is entirely fair, as an exchange of equivalent values.

However, it is in the sphere of production that the use-value of labour-power is expressed. Namely, its capacity — in the given historical conditions of development of the productive forces — to operate for a labour-time greater than the time necessary for the production and reproduction of labour-power itself, thus endowing the commodity, produced for the capitalist, with an exchange-value greater than that of the capacity to work, i.e., higher than the worker’s salary. This surplus part of labour-time, “given as a gift” by the wage-earner to the capitalist, is the source of the income of all bourgeois fractions and of universal wealth accumulated in every form. This is the discovery of surplus value.

Marx wrote to Engels to emphasise the “simplicity” of the discovery: “the economists, without exception, have missed the simple fact that, if the commodity has the double character of use-value and exchange-value, then the labour represented in the commodity must also have a double character, thus the bare analysis of labour sans phrase, as in Smith, Ricardo, etc., is bound to come up against the inexplicable everywhere. This is, in fact, the whole secret of the critical conception”.

That “value as such has no ‘sub-star stance’ other than actual labour” had already been a discovery of Petty’s, “neatly elaborated by Ricardo”. On the other hand, the dual character of value as applied to labour was not yet understood.

How was Marx able to make this simple but great leap in his study of capital? Engels gave an equally simple and profound answer: because Marx saw, behind the relations that classical economics treated as relations between things, relations between people and between classes:

“Economics is not concerned with things but with relations between persons, and in the final analysis between classes; these relations, however, are always bound to things and appear as things. Some economists had an inkling of this connection in isolated instances, but Marx was the first to reveal its significance for the whole of economics, thus making the most difficult problems so simple and clear that even bourgeois economists will now be able to grasp them”.

In the Economic Manuscripts, in several passages, Marx illustrated the transformation, inherent in the capitalist mode of production, of social relations into relations between things. This did not prevent him from recognising precisely in this reification, in this dehumanisation of the system of bourgeois relations, the great merit of the most authoritative economist of the bourgeoisie, David Ricardo. He wrote in book XVI of the Manuscripts: “The reproach that is made against him, that in examining capitalist production he is unconcerned with ‘human beings’, keeping in view the development of the productive forces alone [...] without concerning himself with distribution and therefore consumption, is precisely what is great about him. The development of the productive forces of social labour is the historic task and justification of capital. It is exactly by doing this that it unconsciously creates the material conditions for a higher mode of production”.

It was the pseudo-socialists Proudhon, Sismondi, and the reformist epigones who wanted to humanise the capitalist mode of production. Communists want to abolish it because it has now exhausted its historical task.

Marx begins the first book of the Manuscripts in 1861 investigating money, posing the difficult question: “How does money become capital?". Let us follow Marx’s approach to see one aspect of his scientific method, namely, the meticulous search for every aspect of his object of investigation. His tools are scientific abstraction, logic, and history; historical observation usually follows logical exposition — the “logical method” precedes the “historical method”. Engels observes: “the logical method [...] is indeed nothing but the historical method, only stripped of the historical form and of interfering contingencies”.

Logic and history for Marx are not those of the Scholastics. Antonio Labriola defined Marx’s relentless analytical capacity as the “overextension of logic”. It is none other than a study based on the “science of logic”, on the dialectic transformed and armed with the materialist vision of the capitalist mode of production. The history of capitalist society is conceived as a historical-natural process and as the social praxis of antagonistic classes. Capital overflows with references to the history of classes. Its historical chapters, such as those on primitive accumulation, on the working day, or on the application of science to industry, are vivid depictions of the socio-economic formation, the flesh and blood covering the skeleton X-rayed by theory.

The systematic use of the logic of Capital is both a challenge and an exercise in thinking for young minds, besieged by the fog of received wisdom, by the pressure of digitalised imbecility, by the uncultured irrationality of narcissistic demagogues, and by the cultured ignorance of bad teachers.

Marx’s logic requires and teaches the patience and curiosity necessary to understand the real world.

Class Consciousness and Crisis in the World Order

Internationalism No. 71, January 2025 Pages 1 and 2 The consciousness of the proletariat “cannot be genuine class-consciousness, unless the workers learn, from concrete, and above all from topical, political facts and events to observe every other social class in all the manifestations of its intellectual, ethical, and political life; unless they learn to apply in practice the materialist analysis and the materialist estimate of all aspects of the life and activity of all classes, strata, and groups of the population”. If it concentrates exclusively “or even mainly” upon itself alone, the proletariat cannot be revolutionary, “for the self-knowledge of the working class is indissolubly bound up, not solely with a fully clear theoretical understanding or rather, not so much with the theoretical, as with the practical, understanding — of the relationships between all the various classes of modern society”. For this reason, the worker “must have a clear picture in ...

The Defeat in Afghanistan — a Watershed in the Cycle of Atlantic Decline

In crises and wars there are events which leave their mark on history because of how they make a decisive impact on the power contention, or because of how, almost like a chemical precipitate, they suddenly make deep trends that have been at work for some time coalesce. This is the case of the defeat of the United States and NATO in Afghanistan, which is taking the shape of a real watershed in the cycle of Atlantic decline. For the moment, through various comments in the international press, it is possible to consider its consequences on three levels: America’s position as a power and the connection with its internal crisis; the repercussions on Atlantic relations and Europe’s dilemmas regarding its strategic autonomy; and the relationship between the Afghan crisis and power relations in Asia, especially as regards India’s role in the Indo-Pacific strategy.

Chinese Rearmament Projects Itself in Asia

Internationalism No. 78-79, August-September 2025 Page 5 From the series Asian giants Trends in rearmament spending and comparisons of military equipment are increasingly set to dominate coverage of the contention between powers in the crisis in the world order . The military factor has entered the strategic debate, accompanied by a wealth of figures and technical details. The increase in military spending as a percentage of GDP represents a widespread sign of the rearmament cycle at this juncture, but spending alone cannot entirely explain the situation, given the qualitatively different natures of the arsenals being compared. Nor are comparisons between this or that type of weapon useful in themselves, because ultimately all weapons are only ever used in combination with the complex military means available to a power, either in alliance or in conflict with other powers in the system of States. Therefore, while it is difficult to assess the real significa...

German Socialism in 1917

Internationalism No. 78-79, August-September 2025 Page 6 From the series Pages from the history of the worker’s movement  According to Arrigo Cervetto [ Opere , Vol. 7], “paracentrism” is “the biggest obstacle to the formation of the worldwide Bolshevik party”. The Spartacists at Zimmerwald and Kiental Cervetto was analysing Lenin’s battle against centrism for the creation of the Third International, a battle which saw him isolated at Zimmerwald. He wrote down one of Zinoviev’s quotations from Histoire du parti communiste russe . “We were in the minority at Zimmerwald [1915]. […] In the years 1915 and 1916, we were nothing but an insignificant minority”. “But what is more serious?” – observed Cervetto – “is that the Zimmerwald Spartacists also said they were opposed to us”. In the strategic perspective of the “two separate halves” of socialism – the political conditions in Russia and the economic, productive, and social conditions in Germany – “for ...

Democratic Defeat in the Urban Vote

Internationalism No. 71, January 2025 Page 2 From the series Elections in the USA A careful analysis of the 2022 mid-term elections revealed the symptoms of a Democratic Party malaise which subsequently fully manifested itself in the latest presidential election, with the heavy loss of support in its traditional strongholds of the metropolitan areas of New York City and Chicago, and the State of California. A defeat foretold Republican votes rose from 51 million in the previous 2018 midterms to 54 million in 2022, a gain of 3 million. The Democrat vote fell from 61 to 51 million, a loss of 10 million. The Republicans gained only three votes for every ten lost by the Democrats, while the other seven became abstentions. In 2022, we analysed the elections in New York City by borough, the governmental districts whose names are well known through movies and TV series. In The Bronx, where the average yearly household income is $35,000, the Democrats lost 52,00...

The Comprehensive Agreement on Investment Strengthens the ‘European Party’ in China

From the series News from the Silk Road “Chinese people treat [US democracy] as a variety show which is much more interesting than House of Cards’ [...]”. Beijing does not feel the same embarrassment as the old democracies of the West faced with the grotesque scenes of demonstration against the Capitol organised by the president of the United States. Zhao Minghao from the Chongyang Institute spelled out the obvious in his analysis some time earlier: “the political farce by the incumbent president and some Republican lawmakers is reflecting the profound crisis on US domestic politics.” The Global Times is serving a hefty bill to the ideologies of liberal interventionism: “the ‘beacon of democracy’, and the beautiful rhetoric of ‘City upon a Hill’ [...]” are undergoing a serious debacle or in other words, a “Waterloo of US international image”. It will be a while before the US can “interfere in other countries’ domestic affairs with the excuse of ‘democracy’[...]”. Attention is also...

Uneven Development, Job Cuts, and the Crisis of Labour Under Global Capitalism

Internationalism No. 73, March 2025 Page 16 Uneven development is a fundamental law of capitalism. We have a macroscopic expression of this in the changing balance of power between States: Atlantic decline and Asian rise are the key dynamics behind the political processes of this era, including wars caused by the crisis in the world order. But behind all this there is a differentiated economic trend, starting from companies and sectors: hence the differentiated conditions for wage earners. And this is the element to keep in mind for an effective defensive struggle. It’s only the beginning The electrical and digital restructuring imposed by global market competition affects various production sectors. The car industry is the most obvious, due to the familiarity of the companies and brands involved. We have already reported on the agreement reached before Christmas at Volkswagen, which can be summarised as a reduction of 35,000 employees by 2030. Die Zeit [De...

Socialism and Nationalism in the History of France

The collapse of French socialism at the outbreak of the First World War is considered by many historians to be the most significant case of its kind. We must go back in time to find its origins. The dramatic repression of the Paris Commune in 1871 was followed by a decade of shootings and the deportation of tens of thousands of revolutionary militants. Reactionary monarchical legitimism attributed the decline of France to the Revolution of 1789, but by then the nouvelles couches sociales , the new classes produced by capitalism, as Leon Gambetta defined them, demanded a politics free from economic, social and clerical ties. The Radical Party, a turning point of French politics, was its expression. The same taditional Catholic Judeophobia dating back to the Middle Ages — according to Michel Dreyfus’, research director at the CNRS in Paris, Anti-Semitism on the Left in France [Paris, 2009] — gradually transformed into the image of the Jews associated with money and modernity who des...

Armed Negotiations between the Gulf and the Mediterranean

David Petraeus, Commander of the US forces in Iraq and the Gulf in 2007-2008, then director of the CIA in 2011-12, described the elimination of Iranian General Qasem Soleimani on January 3 rd in Baghdad as a defensive action , with which the Trump presidency restored a US deterrence , which was weakened by recent Iranian actions . This is a reference to the attacks conducted indirectly, unclaimed by Tehran, against the Saudi oil infrastructures on September 14 th 2019. In March 2008, when the forces under Petraeus’ command supported the Iraqi Army in the fight against local Shite militias, Soleimani sent a message to the American general: informing him that he was the person in charge for Iranian policies in Iraq, Syria, Lebanon and Gaza therefore the channel through which to define an agreement to resolve the various issues with Tehran. Petraeus holds the advisors of the Quds Force, the spearhead of the Pasdaran asymmetric operations, responsible for the killing of around 600 ...

Variations and Gradations of Democracy in China

Internationalism No. 50, April 2023 Page 10 From the series Giats of Asia : the dillemas of Chinese single-party pluralism Only the materialist analysis of the intraction between structure and superstructure can explain the variety of the political forms. Why did the entrenchment of the capitalist mode of production in China occur in populist and Maoist forms? Why does Chinese imperialism express itself in CP single-party pluralism and not, for example, in the classical multi-party system of imperialist democracy? This specific political analysis does not regard the study of the economic causes which determine China’s political struggles, a scientific investigation which is its premise, “but the way” in which these struggles present themselves in the superstructure. “By analysing basic economic facts, Marxism can identify at first the interests which find expression in the political struggle. The form in which these interests appear politically, however, is a qu...
