The literature on the Third, or Old, Marx, by which I mean the literature that deals with the last 16 years of his life (approximately from the publication of “Capital” in 1867 to his death in 1883) is becoming increasingly frequent and influential. I have already reviewed Kevin Anderson's excellent "Marx at the Margins". Marcello Musto's "Les dernieres annees de Karl Marx" (I read the book in French) or "The last years of Karl Marx" is an important addition. Musto's original was published in 2016 in Italian, and, as he writes in the preface, has already been translated into twenty languages.
Musto's main thesis, like in other books on the Third Marx, is that Marx’s last years, far from being barren as the common view holds, have been filled with uninterrupted readings in all areas, from ethnography and anthropology to physics, increasing interest in mathematics (which Marx used mostly as a passe-temps) and, most importantly, political and economic discussions that led him further away from the Eurocentric stadial philosophy of history. It is this last part that is, for obvious reasons, most relevant for us today. It "creates" the third Marx: the first being the one of human condition, of "Philosophic and Economic Manuscripts" and "German Ideology", the second, and best known, the one of “Capital” and other economic writings, and the third, the Marx of globalization.
Despite what Musto attempts to prove, namely that Marx was intellectually very active until almost the end of his life, the reader remains somewhat unconvinced by the argument. In fact, as the detailed chronological review of the last years (and especially of the last two years) shows Marx suffered a lot due to his bad health, deaths in the family (of his wife in 1881, and then just before his own death of his oldest daughter), continued to read and make copious notes across disciplines, but did not really produce much. His objective of finishing at least volume 2 of “Capital” was unfulfilled. Finishing volume 3 was not even on the horizon.
The last intellectually significant contribution was Marx's discussion in the seventies, with several Russian authors, of Russia's transition to socialism. That discussion is not only important because of what happened later but because Marx was, for the first time, faced with the question whether his stadial theory of history and ineluctability of socialism, meant also that very diverse societies had to go through the same stages as Western Europe or not. Marx became quite aware of the problem, and papered it over by writing that his schemata were based on West European experience only. This is the non-dogmatic Marx that Musto privileges in his interpretation.
However, the danger of being non-dogmatic is the following: if one admis a multitude of economic systems, or that similar conditions may lead to very different outcomes, one eventually remains without any distinct socio-economic theory, but with many individual case studies. They can be discussed in great detail one by one, and very reasonably so, but this “segmentation” also rules out the inevitability of the ultimate aim that Marx entertained throughout his life: the emancipation of labor, or in other words, socialization of the means of production. If anything can happen, why are we convinced that emancipation of labor is ineluctable?
Looking at the caution with which Marx approached the Russian question (can land held in common be the basis for communist development? does Russia need to develop capitalism first?), one can easily see how very conscient Marx was of the problem. Insisting on Western European stages of history meant irrelevance of his theory for the rest of the world (including India into which Marx was quite interested), but "diluting" his theory too much meant undermining the historical necessity of the ultimate objective. It is only thus that we can understand Marx's hesitation on the Russian question, and numerous drafts of his famous reply to Vera Zasulich's letter.
Musto comes to the conclusion that Marx accepted the Russian populists' view that the commune can provide the basis for direct transition to communism, and against the view that Russian socialists need do nothing but cheer the advance of capitalism in the hope that, when capitalism is sufficiently advanced, it would lead the country automatically to socialism. In other words, Marx accepted the multiplicity of the paths to socialism, and even the political way of achieving this through insurrection and revolution. The multiplicity of the ways to socialism is therefore ideologically compatible with Blanquism or Leninism: audacious political action that may not be fully supported by the "objective" economic conditions, as a way to force history. Lenin's and later Mao's interpretations of Marxism are certainly consistent with this view.
A different interpretation is also possible, but its political implication is "attentisme", that is reformism and pragmatism that eventually took over German Social-democracy and Eduard Bernstein, whom both Marx and Engels thought to be its most promising leader. The two aspects of Marx that are, in theory, indissoluble: a student of historical processes and a political activist, collide. One has to choose what to do: to be a Fabian or a Leninist.
Choosing the latter, that is, "forcing history" leads to some unpleasant conclusions. Not only can "reasonable" voluntarism be endorsed, but even much more “costly” measures too. If it makes sense to use common ownership of land as in the Russian obshchina to build upon it a much more developed, but collectively owned, system, it does make sense, as Stalin did, to proceed to collectivization. Collectivization can be seen not solely as a means to increase agricultural output through economies of scale but to solve the socio-economic puzzle. Stolypin’s reforms and then, after 1917, the seizure of land belonging to nobility had created a very numerous small-holding peasantry. The obshchina mode of production was spontaneously and naturally transformed into a small-scale and increasingly capitalist mode of production. But if a short-cut to socialism is possible, would not the argument that this multitude of small holdings should be combined into a more general collective ownership, supported by more advanced technology, be valid?
The statement on the feasibility of different ways of transition to socialism thus leads one to the acceptance of revolutionary practice as a "midwife" of new economic formations which in turn allows for ever more voluntaristic, or politically-motivated, moves.
Musto does not seem, in my opinion, to fully realize that what seems, from today's perspective, open-mindedness and non-dogmatism of Marx, can lead to the outcomes like collectivization that he rightly deplores. This is the dilemma faced even today: if everything (or most) is a matter of political will, then, with skillful leaders, the underlying economic and social conditions become less important, and one enters the realm of arbitrariness. But if everything is decided by the social “fundamentals”, then there is no role for politics, or there is only a role for the politics of the possible which is timid, boring and self-limiting.
Branko’s conclusions seem to me very weak: either there is a fundamental theory that applies without exception, or it’s all arbitrary, and God help us. Surely a viable social theory must be more nuanced than that. Marx’s theory continues to interest us because it conceptualizes better than any other the capital order we live in, including its ability to cover the developments after Marx (imperialism, the worker as consumer, capitalism as the world system, etc.). Moreover, it allows us to conceive the idea of a transition to a post-capital society, something mankind is in dire need of, if it wants to survive. Whether Marx held a stadial theory of history seems a minor matter; much more important is that in his concept capitalism, once started, will spread to the whole world, whatever the initial conditions in any particular country. 150 years after, we can certify that, indeed, the prediction was correct. What now?
We know in his more productive years Marx - intentionally - did not dwell much on the transition. In his later years, he did think about it; probably his life experience was a factor, having been emarginated from the actual worker’s movement, after giving it its ideology. Certainly the idea of the organized workers, schooled in the factory, taking over the system by a political revolution, subjecting the society to planning, and going on from there, does not do justice to Marx’s complexity of thought – and is patently obsolete now. A social revolution is what he was after, a new mode of production the seeds of which must be sown already in capitalism; the political revolution was only to be the seal placed on a long process of incremental change, just like the French revolution after centuries of bourgeois build-up. History has been different: the revolution in the weakest link, its failure in the West, socialism in one country, and, on the other side, the extraordinary vitality of capitalism, capable of reinventing itself at every step using its opposite, the socialist movement, as its propulsion. Marxism is dead, long live Marx.
The private letter format allows for speculations and more personal views than the official publication format. I'm sure that if we scrutinize private correspondence of any liberal economists we will find a lot of self-doubt, existential crisis and embarrassing stuff.
For purely scientific purposes, we should always limit ourselves to officially published, i.e. finished, writings. When judging modern scientists, we always limit ourselves to peer-reviewed articles, theses, and stuff said or published in seminars et al. - Marx should receive the same treatment.
So, unless one's goal is to produce a biography of the man himself, one should never use Marx's letters as proof or counterproof for anything he published willingly and officially in life, excluding the exceptional case of the last two volume of Capital, which had an exceptional editor (Engels).
Marx was a scientist. He developed a theory, which built a model. A model is not a crystal ball or a receipt, but a scientific scheme with which we can describe and predict what happens in the real world. For example, we learn Clapeyron's simplified formula for gases in high school, which uses the ideal gas as a presupposition (the unidimensional gas particle). Is it absolutely real? No. Does it describe nature well enough so we can understand the concept and predict a lot of things, to a stage beyond human immediate observation? Yes.
Science is not and was never intended to be the absolute truth. The truth is the truth, it exists regardless of the human will, therefore it doesn't require explanation or justification - it simply is. Science is the human understanding of truth to the point to be humanly useful. It build models of truth, not truth.
And reality, as we can observe it right now, points to the direction Marx's theory and its model are scientifically true. The model of capitalism he built in his magnum opus (Capital, the three volumes) is being confirmed, the more data we collect and interpret on capitalism.
Although he never came close to a theory of socialism/communism - he lived long enough to barely finish his theory on capitalism and History - the few axioms he logically deduced from it are being confirmed at a historical scale: the only revolutionary class is the (industrial) proletariat; socialism is the dictatorship of the proletariat; revolutions can only happen violently; it will have to have a superior stage of the development of the productive forces; and so on.
Marx was an extremely consistent philosopher throughout his entire life. Logically, he was indestructible (which is not surprising, since he was a Ph.D. in Philosophy with an specialization in Logic). He never changed his mind and his theory stands the test of time even though countless attempts have been made to dismantle it (since Jevons and the Austrians to the present-day Neoclassicists and Neo/Post-Keynesians). So far, I have not read any counter-theory that could even make a dent to Marx's theory (and I've read a lot, even Bohm-Bawerk's infamous article).
It is also important to highlight the fact that, before 1917, Lenin's interpretation of Marx was considered extremely heterodox by the Marxist circle which was centered in Germany. Lenin was considered a curious and irrelevant case of russified Marxism at the best; an outright ignorant Asiatic barbarian at worst. He was absolutely not taken seriously by the Social-Democrats, and mocking him and the Bolsheviks was one of Rosa Luxemburg's favorite pastimes. The Bolsheviks were considered, by and large, a bunch of lunatics during the beginning of the 20th Century -- to the point the Kaiser allowed Lenin to return to Russia during WWI because he thought that would sabotage the Russian Empire from within (he was right in the sense that it sabotaged Russia as the Crown; he was wrong in the sense that it would sabotage Russia as the People).
The Bolsheviks only became the "holotype" of Marxism in the years following 1917, after the "revolutions" in the West crumbled one by one. By 1923, no serious Marxist in Western Europe doubted the Bolsheviks had found the "correct formula". Nothing like the instinct of self-preservation to change an adult's mind.
