For most Marxist scholars, the âbreakâ between âwesternâ and âsovietâ Marxism (and hence, the beginning of the âEngels debateâ) occurs first in Georg LukĂĄcsâ famous sixth footnote of the first chapter in his 1923Â History and Class Consciousness. Here, LukĂĄcs states that âEngels â following Hegelâs mistaken lead â extended the [dialectical] method also to knowledge of natureâ (43). Instead, argued LukĂĄcs, the dialectical method should be limited to âhistorical-social realityâ (ibid).

â
What those who bank on this footnote forget, or are unaware of, is that LukĂĄcs comes to reject his own position to the point of â[launching] a campaign to prevent the reprints of his 1923 bookâ (55). LukĂĄcs had argued that his book was âoutdated,â âmisleading,â and âdangerousâ because âit was written in a âtransition [period] from objective idealism to dialectical materialismââ (ibid). Additionally, he was quite explicit in arguing that ââ[his] struggle against⌠the concept of dialectics in natureâ was one of the âcentral mistakes of [his] bookââ (56). Further, in the posthumously published A Defense of History and Class Consciousness: Tailism and the Dialectic, LukĂĄcs says that âthe dialectic could not possibly be effective as an objective principle of development of society, if it were not already effective as a principle of development of nature before societyâ (Ibid).
LukĂĄcsâ rectification should also show that he was the one that was following G. W. F. Hegelâs lead, for Hegel held that âorganic nature has no historyâ (162). Therefore, âcontra Hegel and LukĂĄcs, Engels is on the right track because he advances the view that nature has a history, and that it is a self-grounded totality,â i.e., that âdialectics applies to natureâ (201-2).
Notwithstanding, Kangal argues that âthe novelty of LukĂĄcsâ claim is overratedâ (44). Before, during, and after the lives of Marx and Engels, debates concerning dialectics in general, and dialectics in nature in particular, had already been taking place in socialist theoretical circles across Europe. Instead of the orthodox origin story of the debate in LukĂĄcsâ footnote, Kangal âoffer[s] an alternative history of the originâ of the debate which âgoes back to the critical readings of Hegel among his pupils, most notably Adolf Trendelenburg and Eduard von Hartmannâ (44).

After situating the origin of the Engels debate in the Hegel debate of the early 1840s with Trendelenburg, and the late 1860s with Hartmann, Kangal shows how this debate was rekindled during Marx and Engelsâ lives in their debates with Eugen von DĂźhring and their friend Friedrich Albert Lange. Concerning the former, Engels âjokingly complainedâ to Marx while writing Anti-DĂźhring that
You can lie in a warm bed studying Russian agrarian conditions in general and ground rent in particular, without being interrupted, but I am expected to put everything else on one side immediately, to find a hard chair, to swill some cold wine, and to devote myself to going after the scalp of that dreary fellow Dßhring (37).
âMarx appreciatively noted in a letter exchange with Wilhelm Liebknecht the âgreat sacrificeâ Engels made, â[postponing] an incomparably more important work [i.e., Dialectics of Nature],â to provide a comprehensive criticism of DĂźhring (31).
âConcerning their friend Lange, he argued in 1865 that the âHegelian system [was] a step backward towards scholasticism,â and that Hegelâs views on mathematics and natural science were a substantial âweak spotâ (47). In the same year Engels sent him a letter defending âthe titanic old fellowâ and argued that Hegelâs âtrue philosophy of nature is to be found in the second part of the âLogic,â in the theory of essence, the authentic core of the whole doctrineâ (ibid). To this he added that the âmodern scientific doctrine of reciprocity of natural forces [was] just another expression or rather the positive proof of the Hegelian development on cause & effect, reciprocity, force, etc.â (ibid). Kangal notes that Langeâs latter work shows he took âEngelsâ comments on Hegel seriously,â to the point of having developed in the posthumously published Logical Studies a âdialectical theory of probabilityâ (48).In addition to the debates during the lifetime of Marx and Engels, Kangal also covers the debates that took place in the interlude between Engelsâ death and the Russian 1917 revolution. For instance, he presents the arguments of the Russian Khaim Zhitlovskii (1896), who was the first to attempt a divide between Marx and Engels on the subject of natural dialectics; the arguments from the German revisionist Edward Bernstein (1921), who argued that âthe great things which Marx and Engels achieved, they accomplished in spite of, not because of, Hegelâs dialecticsâ; the critical reply from the Austrian Marxist philosopher Karl Kautsky (1899), who in seeing and affinity between Bernstein and DĂźhring rhetorically asked (quoting Engels), âwhat remains of Marxism if it is deprived of dialectics that was its best âworking toolâ and its âsharpest weapon?ââ; and lastly, the debates between Austrian-Marxist Max Adler (1908) and the Russian Marxist Georgii Plekhanov (1891) over the formerâs attack, and the latterâs defense, of philosophical materialism and dialectics (49-52).Kangal also provides a thorough study of the debates and contradictions that arose in the Soviet Union concerning the relationship of Marxism to Hegel, Marxism to philosophy, and of dialectics to nature. Focusing on the debates between the Deborinites and the Mechanists, Kangal brilliantly shows the plurality and heterogeneity of Marxist thought that existed in the Soviet Union. He says, âit is no exaggeration to say that the Soviet debates accumulated an astonishing variety of contradictions, even if some figures embodying those ambiguities, or later historians narrating them, would not openly admit thisâ (60).In journals like Pod Znamenem Marksizma (âUnder the Banner of Marxismâ), Vestnik Kommunisticheskii Akademii(âBulletin of the Communist Academyâ), Bolshevik, and Dialektika v Prirode (âDialectics in Natureâ) these debates would openly take place between scholars and party theoreticians (ibid). The research Kangal does of these Soviet debates lucidly depicts the monumental ignorance of âwesternâ Marxistsâ dogmatic critiques of what they labeled as âSoviet Marxism.â Such homogeneity never existed, plurality and debate were always present. Only in the anti-communist plagued minds of western Marxists did such homogeneity exist in Soviet philosophy.

âOne of the novel points Kangal stresses is that the â197 manuscript fragmentsâ contained in the âfour foldersâ that would be made into the book we now know as Dialectics of Nature (or Dialectics and Nature for the 1927 German edition), has its âcompleteness and maturity⌠editorially imposedâ (58, 3). This is something that has been mostly ignored by both sides of the Engels debate, each which assumed that, although incomplete, the book had a single and consistent intention it aimed to carry out. In response to this historical misreading of Engelsâ intentions, Kangal states that,
âThere is not necessarily a single overriding intention, a single goal, and a single argument in his entire undertaking; Engelsâ readers do not appear to be prepared to accept the fact that some of his intentions, articulated or otherwise, might be incomplete, or incongruent with his other intentions, goals and arguments (184).
âConsidering the former, Kangal argues that Engelsâ âwork in progress⌠remained incompleteâ (124-5). This âincompleteness theorem,â as Kangal names it, states that âit is by no means self-evident that Engelsâ project was ânot finishedââ (125). As he notes, a work can be âcompleted without being publishedâ (ibid). A good example of this is The German Ideology, which although left to the âgnawing criticism of the mice,â nonetheless completed its âmain purpose â self-clarification.â[5]One must ask, then, â why did Engels embark on such a momentous project? After providing a magnificent Marxist analysis of the function of theory and its relationship to practice, of the role of intellectuals in the workersâ struggle for socialism, and of the role of philosophy in relation to theory and practice, Kangal postulates four main motives behind Engelsâ project: 1) âthe political goal was to win over all (potentially) progressive forces, including natural scientists, to the socialist causeâ; 2) to provide the natural sciences â who although think themselves to be free of philosophy are actually, according to Engels, always âunder the dominion of philosophyâ â the âmethodological indispensability of philosophical dialecticsâ; 3) to consciously incorporate into the theoretical sciences the only method capable of comprehensively understanding the results derived from scientific studies â the Marxist materialist dialectics; and 4) to move beyond Ludwig Feuerbachâs insufficient discarding of Hegel, and instead sublate Hegel by showing that his revolutionary method is confirmed in nature and its historical development (something which Hegel rejected) (111-13).
In addition, after Marxâs death, Engels realized that Marx had never written the â2 or 3 sheetsâ he promised to him and Joseph Dietzgen where âthe rational aspectâ of Hegelâs method would be made âaccessible to the common readerâ (108). This, argued Kangal, was also an âoccasionâ (instead of a âdirect reasonâ) for Engelsâ undertaking in Dialectics of Nature (110).
After covering the Engels debate both contextually and genealogically, and providing a textual history of Dialectics of Nature and the multiple purposes behind it, Kangal dives into the most philosophically dense part of the book â his critical assessment of dialectics in Engelsâ text. It is important to remember that although the critiques are directed at Engels and his Dialectics of Nature, the flaws Kangal points to are in Marx as well, for their perspectives on these were waged jointly. Here are some of the most important critiques Kangal provides of Engelsâ âphilosophical ambiguitiesâ (125).

1- There are quite a few ambiguities and loose ends with Engels (and Marxâs) treatment of Hegel. First, Engels incorporates Hegelian categories (primarily from the first two sections of Hegelâs Science of Logic and Shorter Logic â the âLogic of Beingâ and the âLogic of Essenceâ) without an explanation for the differences in order and prioritization in how they appear in his and Hegelâs work. In Engelsâ treatment, for instance, the categories from Hegelâs chapter âThe Essentialities or Determinations of Reflectionâ (quantity/quality, identity/difference and its development into the categories of opposition and contradiction), are conjoined with the category of sublation (aufhebung) which Hegel introduces at the beginning of the âLogic of Beingâ, and are raised to the status of being âdialectical laws,â that is, âthe most general lawsâ of the âhistory of nature and human society.â These are, of course, the famous three â the âlaw of the transformation of quantity into quality and vice versa, the law of the interpenetration of opposites, [and] the law of the negation of the negation.â[6]
Why he chooses these to be âlawsâ over other Hegelian categories he uses throughout his work (like force/manifestation, coincidence/necessity, causality/reciprocity, shine/essence, nodal line, etc.) is unclear. Similarly, why some of Hegelâs categories are fully discarded with is also left unexamined. In addition, the treatment of Hegelâs Logic (which he primarily uses the Shorter Logic for) contains no consideration for Hegelâs Phenomenology of Spirit, which Hegel argued his Science of Logic was the âfirst sequelâ of.[7] With the exception of his critiques of Hegelâs philosophy of nature (which is part two of the Encyclopedia of the Philosophical Sciences), Engels leaves what comes before and after the first division of Hegelâs Logic[s] (the sections in Objective Logic) largely unexamined.
The problem here is that it was Engels who, against Feuerbach, argued that Hegel couldnât just be discarded, that his philosophy had to be âsublated in its own termsâ (113). By discarding such a large amount of Hegelâs work, and further, by leaving largely unexplained the reasons for using those parts of Hegel which he does, Engels replicates (in a more advanced form) the Feuerbachian discarding of Hegel and fails to fully meet his own standards.
2-Â There are two central bifurcations Engels is engaging with in this text: dialectics and metaphysics, and idealism and materialism. As every Marxists knows, dialectics and materialism are supposed to be the âgood guysâ and metaphysics and idealism the âbad guys.â However, as Kangal shows, what allows for this neat separation is a synecdochal understanding of idealism and metaphysics on the part of Engels. Contrary to the common Marxist understanding, Kangal shows that there is a âcompatibility rather than divergence between materialism and âa specific sort of) idealism, and between dialectics and (a specific sort of) metaphysicsâ (6).
Surely, Engels rejects Hegelâs depiction of the ârealization of Spiritâ or the âexternalization of the Ideaâ by postulating the âprimacy of nature over logic.â But this âinversionâ of what Hegel calls in his Philosophy of History a âtrue Theodicyâ is not in itself a rejection of idealism en toto, but of a specific aspect of a particular philosopherâs (Hegel) objective idealism.[8] As Kangal states,
âHegel and Engels diverge in the following respect: materialism regards nature as a self-grounded totality with its own history, while this is denied by idealism. Idealism presupposes a âSpiritâ that precedes nature into which it âexternalizesâ itself. Engels has no reason to commit himself to Hegelâs religious mysticism, but this, in turn, is no sufficient reason to discard âidealismâ in Hegelâs sense of the term (194).
ââThis wholesale discarding of idealism is shown to be even more absurd by the fact that part of Engelsâ critique of the natural sciences, specifically his appeal for a conceptually realist understanding of âreal infinities,â is itself an argument for what Hegel would call âidealismâ (126). Idealism (in Hegel specifically) argues that,
Singular finite entities have no veritable being without collective dependence and mutual interaction among each other; mutual interdependence of finite parts is an infinitely self-developing totality within which the singular parts play the role of individual moments of the whole (157).
ââWith this Hegelian definition of idealism Engels would be in full accord. The only thing he would disagree with is the characterization of the above mentioned as âidealismâ. However, âthe infinite stands and falls within the area of idealist investigation insofar as it is not subject to finite empirical observations of particular natural sciencesâ (194). Hence, it would be superfluous to come up with another term for the investigation of the infinite. The term âidealismâ is sufficient here.Engelsâ unorthodox and synechdochal understanding of idealism (as it appears in the Hegelian tradition at least) is at the core of his (and Marxâs) artificial bifurcation of materialism and idealism. Instead, Kangal argues, we must realize that a âlocal materialismâ and a âglobal idealismâ are perfectly compatible (195). Kangal adds that he âwouldnât be surprised if it had been a similar conclusion that prompted Leninâs emphasis on the âfriendshipâ between materialism and idealismâ (205).

3- Engelsâ treatment of metaphysics suffers from the same setbacks as his treatment of idealism. For instance, in Anti-DĂźhring he argues that âto the metaphysician, things and their mental images, ideas, are isolated, to be considered one after the other and apart from each other, fixed rigid objects of investigation given once for all.â[9]However, this definition of metaphysics synecdochally depicts what Immanuel Kant and Hegel would call âold metaphysicsâ as metaphysics en toto. As Kangal notes, âKant and Hegel famously attack the flaws of âold metaphysicsâ, but Engels takes the anti-dialectics of the old metaphysics to represent the defects of metaphysics as a wholeâ (195).

Metaphysics, in the Hegelian tradition specifically, understands that,
âRational foundations of sciences demand a rigorous inquiry into the fundamental structures of reality and our understanding of them; in order to conduct such an inquiry, we need to construct a categorial framework that explicitly formulates and self-critically revises the conceptual tools in use in order to improve our command of the ways we experience and think of the world (157).
âOnce again, Engelsâ text is littered with examples which depict his agreement with the above-mentioned propositions. The only disagreement here is terminological, that is, Engels would only reject the term metaphysics being used to describe the former perspective. This rejection, however, is grounded on his stinted understanding of metaphysics qua old metaphysics. There is, then, no contradiction at all between dialectics and metaphysics as described above. In fact, as Kangal rightly states, âEngelsâ defense of philosophy against positivism is a defense of âmetaphysicsâââ understood in these terms (195). For Hegel â who Engels and Marx praise and consider as the point of departure for Marxist materialism â one cannot escape metaphysics, human beings are âborn metaphysiciansâ; all that matters is âwhether the metaphysics one applies is of the right kindâ (161).[10]
âKangalâs text also explores how the ambiguities present in Engelsâ understanding of the relationship of idealism and materialism, and metaphysics and dialectics, are reflected and refracted into further confusions and knots concerning his association with Aristotle and his disassociation and critique of Kant. His text additionally traverses how these ambiguities are intensified by the variances between Engelsâ Plan 1878, Plan 1880, and his four folders for Dialectics of Nature (165-176).
It is impossible to do justice, in such limited space, to such a wonderful work of Marxist scholarship. What I can say is this, any reader of Kangalâs book will surely appreciate its abundance of letter references and its resuscitation of texts which have been largely obscured in anglophone Marxist scholarship over the last half a century. Even in the most philosophically muddy places of Kangalâs text, he does an exceptional job at clarifying things for the reader. In contrast to what a recent critical reviewer of Kangalâs text argued, the difficulties found in the philosophically densest section of the text are not the fault of Kangal, but of Engels (and Marx, who shares Engelsâ flaws), who uses unorthodox and synechdochal definitions of idealism and materialism, and dialectics and metaphysics, to position himself in relation to Aristotle, Kant, and Hegel. If anything, Kangal must be thanked for untangling, in his comparative and critical analysis of the aforementioned thinkers, knots set by Marx and Engelsâ philosophically unorthodox usage of the previous concepts.
