Brill’s Companion to German Platonism explores how Plato was interpreted and appropriated by some of the leading thinkers of the history of German philosophy, from Nicholas of Cusa to Hans Georg Gadamer. The book includes fifteen chapters, each of them devoted to one author or school, written by outstanding scholars. While most of the contributions deal with the reception of Plato’s epistemology and ontology, some others also—or only—address the long-disputed issue of how to interpret Plato’s philosophy. Since it is not possible to discuss all the topics in this almost four-hundred page volume, the review is limited to discussing how Plato’s most famous and controversial doctrine, the so-called theory of forms, was interpreted by German philosophers. More specifically, I will pay special attention to what we might call—to use the terminology suggested by the editor—the ‘transcendental interpretation’ of Plato’s theory of ideas. In the following lines, I focus on how this reading emerged and was developed by German philosophers in their various ways of endorsing, modifying, or rejecting Plato’s thought.
Alan Kim’s Introduction (chapter 1) provides an overview of the topics discussed by each of the contributors and identifies the two conflicting interpretative models already mentioned: the ‘transcendental’ or ‘functional’ reading of the ideas, on the one hand, and the ‘transcendent’ or ‘substantial’, on the other (2). According to the latter, which is the most common interpretation of Plato, ideas are separated substances that exist in a transcendent sphere of reality. Under this view, the forms are conceived as the true objects of knowledge and the soul is said to gain access to them through intellectual intuition. On the other hand, the former reading does not understand the forms as objects, but rather as ‘transcendental conditions of possible experience’ (3). The transcendental reading thus rejects the realism and dualism associated with the transcendent one and does not consider ideas as objects of intuition, but rather as functions of understanding. Among the figures examined in this volume that ascribe to Plato the substantialist view are Kant, Schleiermacher, Schopenhauer, Nietzsche, and Heidegger. On the other side, the functional interpretation was anticipated to some degree by Nicholas of Cusa, Leibniz, Mendelssohn and Hegel, and explicitly supported and developed by Cohen, Natorp and Husserl.
In the first chapter after the introduction (2), Claudia D’Amico presents a detailed study of the manifold connections between Nicholas of Cusa and Platonism. She also provides a valuable survey of German authors that in one way or another were influenced by Cusanus’ thought. As for the understanding of Platonic forms, Nicholas of Cusa criticizes Plato for conceiving ideas as separated forms, suggesting instead that while forms are real, they do not exist separated from things. Cusanus thinks that real forms are inaccessible to human reason, only capable of forming conjectures.
In chapter 3, Jack Davidson examines how Leibniz incorporates Plato and Platonism into his own philosophical system. Among the most remarkable points of agreement between both philosophers, Davidson points out Leibniz’s rejection of materialism and his conviction that reality ultimately consists of immaterial, intelligible substances, of which sensible things are appearances (53). After indicating other points in which both philosophers converge, the author devotes epigraph 5 to show how Leibniz’s epistemology reshapes some Platonic themes. More precisely, this section focuses on the agreements and disagreements regarding the role and nature of innate ideas. As it is well-known, Leibniz holds that some of the most fundamental concepts are known innately. At the same time, however, he rejects two positions he ascribes to Plato: the pre-existence of the soul and the presupposition that every truth one knows has been explicitly known by the soul before (63). Despite the emphasis that Leibniz puts on his differences with Plato at this point, both philosophers agree on a fundamental level, as Davidson suggests, that sensible experience does not suffice to account for our knowledge of necessary truths. Thus, the human soul must be equipped with a special potential to know them (ibidem).
The next chapter, written by Bruce Rosenstock, studies Moses Mendelssohn’s appropriation and reworking of Plato’s Phaedo within the framework of his ‘Leibnizian Platonism’ (79) in his own Phädon. Rosenstock focuses on the ‘infinitesimal calculus of the soul’ as Mendelssohn applies it in his own version of the dialogue. The application of Leibniz’s infinitesimal calculus leads Mendelssohn to endorse a functionalist view, since he believes that the soul’s process of knowledge works—like that type of calculus—by progressively ‘integrating’ the initially indistinct mass of representations’ (83). Thus, following Leibniz, Mendelssohn understands the soul as an active Platonic idea that brings unity into multiplicity (84). However, as Rosenstock indicates, this is only one side of the story. Under Mendelssohn’s view, the Platonic ideas do not only account for the integrative nature of human knowledge; they are not merely abstract objects of understanding, but also and at the same time ‘the object[s] of the soul’s authentic (philosophic) desire for happiness’ (92). In this sense, the soul’s capacity to unify the multiplicity of appearances through conceptual unities is the ‘expression’ of the soul’s desire for happiness (93). Hence, according to Mendelssohn, the search for knowledge is necessarily entangled with the quest for the good (92).
In chapter 5, Manfred Baum examines Kant’s appropriation of the theory of ideas in both the pre-Critical and the Critical period. It is worth noting, first, that Kant never attributes the two-world doctrine to Plato, even though his primary source, Brucker, does it. The Kantian pre-critical reading of the Platonic idea assimilates it with a ‘common standard of perfection’ for measuring all other less perfect realities (115). In the critical period, Kant’s well-known differentiation between understanding and reason leads him to reshape his reading. Under this new light, Plato’s ideas are interpreted as anticipating to some extent Kant’s concepts of reason, the regulative ideas, in contrast with the concepts of understanding, the categories (123-124). According to Baum, both Kant and Plato agree that ideas do not originate in the senses and that their object is not found in the empirical world (ibidem). However, Kant rejects the alleged hypostatized nature of Platonic forms, that he presumably takes from Bruker’s Neo-Platonic interpretation of Plato (126-127). The result of Kant’s appropriation of Plato’s theory of ideas, then, is twofold (as Kim also puts it in the introduction ): Kant attributes to Plato a substantial or transcendent view of ideas, while at the same time he sees Platonic ideas as the first attempt towards a transcendental consideration of human knowledge.
Hegel’s reading of Plato can be seen, as Jere Surber persuasively presents it in chapter 6, as the first modern philosophical interpretation of the Platonic corpus (133). The most distinctive features of the Hegelian approach to Plato are, first, Hegel’s direct and detailed engagement with the dialogues and, second, his distinctive appropriation of the Platonic ideas. According to Hegel, Plato’s ideas anticipate in a still unsystematic way his own systematic account of genuine Begriffe (concepts) as “concrete universals” (141). Relying on his interpretation of Parmenides, Timaeus, and Republic, Hegel rejects the dualistic, transcendent interpretations of the forms. He suggests instead that the Platonic idea should be understood as an ‘identity-in-difference’, and therefore as a genuine concept in Hegelian terms, that is, one that unifies in itself the formal and material aspect of reality (136). On the other hand, Hegel also dismisses the psychological transcendentalism according to which the ideas are mere constructs (or mere concepts, as opposed to genuine concepts) of the human mind since this view fails to account for the essential connection between the ideas and the sensible things (p.136). Therefore, as Surber points out, Hegel thought of his own philosophy as the articulation of Plato’s ‘in a modern systematic form’ (142).
The following two chapters (7 and 8) are devoted to Schleiermacher’s influential approach both to Plato’s philosophy and its interpretation. In chapter 7, André Laks provides an insightful discussion of Schleiermacher’s both philological and philosophical reading of the Platonic dialogues. Regarding the interpretation of Plato’s ideas, Schleiermacher rejects Aristotle’s criticisms and defends that the forms are real concepts that actually possess causal force and can directly affect both the physical and the moral world, given that they derive from God’s power (155). Chapter 8 is at odds with the rest of the contributions since it does not offer a reconstruction of Schleiermacher’s reading of Plato, but rather presents the author’s (Thomas Szlezák) main reasons for disagreeing with it. While the philological arguments provided by Szlezák are highly illuminating, and many of his objections to Schleiermacher are indeed very persuasive—see, for instance, his detailed analysis of Plato’s critique of writing in the Phaedrus (172-179)—, one cannot but wonder why Schleiermacher’s interpretation is the only one subject to such critical scrutiny. Besides, the main objections of the Tübingen School–to which Szlezák belongs– to Schleiermacher are again developed and argued for in chapter 14 by Vittorio Hösle. In his contribution, Hösle also provides a valuable survey of some of the most representative advocates of the abovementioned school and provides a summary of the main points of Krämer’s pioneering dissertation Arete bei Platon und Aristoteles, still only available in German (337-339).
Robert Wicks’ chapter on Schopenhauer (9) stresses the role of Plato’s account of time in the former’s metaphysical account of human consciousness and reality. More specifically, according to Wick, the Platonic conception of time as ‘the moving image of eternity’ in the Timaeus inspired Schopenhauer’s consideration of the spatio-temporal world as a prison of human consciousness (192 and 215). In his mature philosophy, Schopenhauer regards Plato’s ideas as essentially dependent on the Will, which constitutes the core of reality, the thing-in-itself, which lays beyond any form of representation and time (209). Under this view, ideas are said to play an intermediary role between the thing-in-itself as Will, on the one hand, and the objects of the spatio-temporal world, on the other (210). Therefore, as Wick suggests, Schopenhauer’s reading of ideas within this framework attributes them a twofold nature: as long as they are objects, they ultimately belong to the world of representation and, to this extent, they are high-ranking illusions; however, considered in their relationship to the thing-in-itself, ideas are ‘timeless acts of Will’ (213-214). In this last sense, Plato’s forms are placed behind the veil of the ordinary experience of the world, and thus they are only apprehended by a certain timeless intuition that Schopenhauer identifies with an intense awareness of the present moment (200-201). Philosophy is thus conceived as a form of asceticism whose aim is to reach such timeless, transcendent, and even mystical awareness (215). As Richard Bennett stresses at the beginning of chapter 11, Nietzsche regards this ascetic approach to reality—that he attributes to Plato—as anti-natural, coward, and decadent (249-252). In the second section of his contribution, Bennet proves that Nietzsche’s consideration of Plato goes far beyond this one-sided evaluation and is more multi-faceted and less consistent than usually acknowledged.
The transcendental reading of Plato’s ideas was explicitly defended for the first time by the two leading figures of the Marburg School of Neo-Kantianism: Herman Cohen and Paul Natorp. In chapter 10, Karl-Heinz Lembeck examines both authors’ attempts to mediate between Kant and Plato in their ambitious philosophical-historical interpretations (217). Cohen’s early reading of the forms as psychological categories radically evolved in the mid-1870s into a purely logical-transcendental interpretation of them. Under this new approach, and drawing on Kant’s Critique of Judgement, ideas are now viewed as ‘regulative concepts’ guiding knowledge. Within this picture, the form of the Good is not seen as a real entity, but rather as ‘the function of a unifying synthesis of appearances’ (223-224). Cohen extracts this interpretation from Plato’s alleged identification of ideas as hypothesis, that is, as ‘pre-sub-positions’ which thinking anticipates in order to be able to apprehend reality (228). In other words, ideas are said to be a priori conditions of knowledge.
Unlike Cohen’s, Natorp’s appropriation of Plato is grounded on a deep engagement with the texts. In Platons Ideenlehre (Plato’s Theory of Ideas), Natorp develops his reading of Plato’s theory of ideas as a theory of the constitution of experience (231-232). From this standpoint, Natorp downplays the ontological significance of the ideas, stressing their epistemological relevance as ‘laws’ that govern the dynamisms of knowledge (233). In his late systematic philosophy, Natorp modifies his reading of Plato’s ideas, as he seems to come under the influence of Neo-Platonism. Now, forms are understood as categories and, as such, as secondary functions unable to grasp the ultimate level of reality. Such level corresponds to Plato’s form of Good, which is radically transcendent and, therefore, inaccessible by means of articulated knowledge (237).
In the next chapter (12), Alan Kim explores Husserl’s ‘productive appropriation of Plato into phenomenology’ (273), relying on the fact that Husserl considered himself a phenomenological Platonist. By doing this, Kim provides an original, perceptive reading of the theory of ideas from a phenomenological perspective and, at the same time, a compelling presentation of the Husserlian account of eidetic intuition. In a way akin to Cohen and Natorp, Husserl endorses a transcendental interpretation of Platonic ideas, rejecting the ‘static’ Platonism of separated substantial forms along with its subsequent metaphysical dualism and mystical intuitionism (274). According to Kim, Husserl’s ideas or eidê refer to the object of the apprehension of the what-ness of a given thing. Such eidê, however, differ from the empirical universal concepts derived by abstraction from contingent facts. Eidê also relates to facts, but not because they derive from them, but rather because they constitute the rule of any possible apprehension of them. In order to illustrate the process by means of which consciousness moves from facts to eidê, Kim draws on Plato’s Divided Line and Allegory of the Cave. The first is meant to represent the different psychic states, while the second focuses on the soul’s progression from one to another. Here, eidê are presented as logical structures or essential meanings ‘that had always been co-intended in my aesthetic grasp of the phenomenon as actual thing, but which had been, as it were, eclipsed by the glare of ‘reality’’ (278). The ascension of the soul towards the realm of ideas is thus understood as a progressive detachment and liberation from the blinding glare of sensible appearances of things, so as to be able to perceive the essential features of them. This interpretation explains both the fact that the highest form of knowledge according to Plato, namely, dialectics, is said to deal only with ideas, and also that the knowledge of ideas allows the ex-prisoner in his return to the cave to recognize images as what they really are (280). In the following pages, Kim equates both Husserl’s and Plato’s account of the vision of eidê with the ‘understanding of the F-ness of many f’s’ (281). As the author points out in a footnote, the state of consciousness in which we grasp an eidê is not adequately described as a learning process, that is, as certain acquisition of knowledge, but instead as some sort of perceiving or, even more accurately, re-cognizing (erkennen) (281, n. 70). In this sense, the phenomenological method of purifying the mind from its factual intentions and redirecting it towards the essential turns out to be very similar to Plato’s account of dialectic as a process of remembering (anamnesis) what one already knows in his or her soul (281). Within this framework, Kim forcefully argues that Husserl’s basic idea of a ‘noematic form implicitly governing the coherence of sense experience’ can be paralleled with Plato’s account of the relationship between noêsis and aisthêsis in the passage on the summoners in Republic VII, as well as with the role attributed to sensibility in the recollection argument offered in the Phaedo. Finally, the author points out that the Husserlian reading was deeply influenced by Lotze’s thesis that ideas do not possess existence (Sein), but rather validity (Geltung) (294).
The two remaining chapters are devoted to Heidegger’s confrontation with Plato (chapter 13) and Gadamer’s productive reshaping of the Heideggerian reading (chapter 15). Francisco J. Gonalez begins his chapter on Heidegger’ reading of Plato by focusing on the 1924/25 course on Plato’s Sophist. In these lectures, it becomes apparent a tension that characterizes how Heidegger will read Plato the rest of his life. On the one hand, the Heideggerian approach reveals several points where Plato’s understanding of being comes very close to Heidegger’s fundamental ontology. On the other, the German philosopher insists that Plato interpreted being as presence, that is, as the object of logos, and therefore that Plato’s philosophy is to be seen as the first of a long series of reductions of truth to correspondence (306). As Gonzalez clearly shows in his contribution, this tension will persist until the late Heidegger, although the latter approach will become the ‘official’ reading. The author suggests that one of the most remarkable exceptions to the official reading can be found in the Parmenides seminar of 1930/31. Drawing on both Heidegger’s class notes and Herbert Marcuse’s transcript of this seminar, Gonzalez clearly shows that Heidegger saw Plato’s discussion of exaiphnês (instant) in the Parmenides as a genuinely ontological comprehension of the problem of ‘being and time’ (314-315). We find a similar exception in Heidegger’s interpretation of erôs in the Phaedrus seminar of 1932 (319 ff.). Gadamer’s appropriation of Platonic philosophy, discussed by François Renaud in the final chapter (15), reacts against Heidegger’s official reading. Gadamer claims that ‘Plato is not a Platonist’ and argues that the theory of forms and the method of dialectic are meant to make explicit the conditions of Socrates’ practice of dialogue in the early dialogues (356). According to Renaud, Gadamer seems to think that the forms are objects independent from representation, though he also speaks of them as if they only were transcendental principles (374).
This volume is worth reading for both historical and philosophical reasons. Each of the fifteen chapters provides the reader with valuable insights into the history of German philosophy in line with the most updated research and effectively supports the general thesis of the book that Plato exerted a decisive influence over the most relevant German philosophers (1). On the other hand, anyone interested in the interpretation of Plato’s works will surely find this book an exciting source of inspiration. In particular, as I hope to have shown, it will prove especially helpful for those intrigued by the possibilities of a transcendental reading of Plato’s theory of ideas. Last but not least, this collective work reminds us of both the risks and benefits of a philosophical reading of Plato, that is, one that attempts to identify and rethink the core issues of Platonic philosophy anew.
Felix Duque is arguably the most important living philosopher in the Spanish-speaking world. Remnants of Hegel is the first book translated into English. It is not a mere interpretation of Hegel, but rather a critical study that attempts to drive the aspects of its subject matter toward their ultimate consequences using Hegelian criteria. In other words, if Hegel’s philosophy is a critique of Kant’s critical philosophy, then Duque’s exposition is a critique of Hegelian philosophy. Furthermore, and just as Hegel develops Kantian categories in order to reveal a truth that goes beyond Kant, Duque develops Hegelian concepts in order to deduce a truth that transcends them. Indeed, Duque says that “The Hegelian system, impressive as it is, ultimately reveals itself as a miscarried attempt to reconcile nature and theory, individuality and collective praxis” (Duque, x).
Moreover, I should begin my review by noting that the book is clearly written for readers who are well acquainted with Hegel’s philosophy. In this respect, my review will attempt to overcome this difficulty by limiting itself to a reading that makes it accessible to those who are not conversant with this philosophy.
The book itself contains five chapters:
Chapter I: Substrate and Subject (Hegel in the aftermath of Aristotle). This chapter is concerned with the famous expression made in the preface to the Phenomenology of Spirit: “According to my view of things, which can be justified through the exposition of the system itself, everything depends on apprehending and expressing the true not as [nicht als] substance, but just as much [eben so sehr] as subject” (Duque, 17).
Chapter II: Hegel on the Death of Christ, is a discussion that seeks to analyze the transition from nature to society, or, rather, the transition from a natural human being to a historical being, and to a being having a second nature, which is the political life of man, a transition which is made possible by the understanding of society and politics as a higher level of self-consciousness.
Chapter III: Death Is a Gulp of Water. This chapter is concerned with terror in World History. More specifically, it is a critical exposition of Hegel’s idea of revolution and terror which primarily refers to the French Revolution. The politics of terror, the chapter argues, is the necessary result of trying to implement the revolution without mediations, that is, directly and as an abstract revolution (Duque, 83). Here Duque does not limit himself to an analysis of Hegel and his time, but also deals with its historical reception by the likes of Communism and Stalinism in the twentieth century. Such an idea of terror does much to radically undervalue the value of life and also makes us remember Hanna Arendt’s Banality of Evil. Indeed, terror is, paradoxically, a result of the French Revolution in its historical imagining of Napoleon, namely, the principles of liberty, equality and fraternity as mediated by his political force appearing as the opposite of those values’ true essence.
Chapter IV: Person, Freedom, and Community is an analysis of the last chapter of Hegel’s Science of Logic which is concerned with the notion of the absolute idea. It is an essential problem to understanding the book as a whole since Hegel begins and ends the book by praising this notion rather than explaining or developing it.
Chapter V: The Errancy of Reason. This chapter summarizes the previous chapters and engages in a holistic critical analysis of the topics discussed.
I would now wish to develop some ideas on Hegel inspired by reading Duque’s work and by my own understanding of Hegel’s philosophy.
Hegel’s logic is not normative. Unlike formal logic, which determines how we should think and not how we actually think, Hegel‘s Science of Logic, proceeds in the opposite direction by studying thought as it is as well as its development from the most abstract stage (the thought of pure being without further determinations) to the most concrete, this being the absolute idea as the unit of theoretical and practical thinking. Duque’s interpretation adopts this principle, and unlike the interpretations offered by Alexandre Kojève and many others, asserts that it should be taken literally, that is, by not trying to correct the author in order to understand him! Understanding by correcting makes the original a tabula rasa since it allows the interpreter to introduce any idea as it occurs to her or him to the work in the belief that it is an interpretation, while it is actually a creation of her or his own mind.
Hegel’s Logic is a reflective study of the concept. In Duque’s words, “the entire Logic is nothing but a relentless attempt to furnish a conscious and deliberate reconstruction of fugitive and fleeting linguistic forms and determinations.” (Duque, ix). The terms in his Logic do not have the fixity that they have in formal logic (both classical and modern), but their meaning varies according to the context, and especially according to the level in which the study is developed. Hegel perceives only the term, the word, as fixed, but not the concept or content that is expressed through words.
Hegel’s logic attempts to solve the classic problem of Aristotelian logic, in which “to say what something in the last instance really is, its ultimate logos, amounts to affirming all the affections, properties, and determinations of that thing” (Duque, 4). Hegel, however, is not successful in resolving this difficulty despite believing he is.
Hegel suggests that thought and reality, as well as mind and world, are inseparable in the sense that their meaning undergoes constant change and construction with respect to the conceptual level and context in which it takes place. A concept’s level of abstraction or concreteness thus simultaneously determines the degree of reality to which it refers. Put differently, this reading suggests that the Science of Logic ultimately serves as an ontological proof which not only proves the existence of God but also the existence of every concept subjected to actual thought. In other words, if I really believe in the concept of having a hundred thalers in my pocket, and not merely imagining them, then the hundred thalers become real and become part of my patrimony. I thus either have them in my pocket or, alternately, owe them and am obliged to pay them. This is not the case with Kant, since he merely imagines them, that is to say, recognizes from the very outset that they are not real thalers. This, in turn, is the difference between abstract and concrete concepts.
The process of concretion is clearly explained in the “logic of the judgment” discussion in the third part of Science of Logic, which is nothing but logic from the perspective of the relationship between the two essential components of judgment—subject and predicate. Thus, every judgment announces that the subject is the predicate. More explicitly, the subject of the judgment is the entity whose identity is being subjected to inquiry, and the answer is offered by all the predicates that refer to that subject. Each predicate thus changes the meaning of the subject, and, in reality, amplifies its meaning. In this respect, a subject is enriched by having more predicates attributed to it – as each of the latter forms another subject with other questions. In other words, to think is – formally – to pass from the subject, which functions as what is unknown and in need of becoming known, to the predicate, which functions as what is known and therefore as what bestows knowledge and meaning on the subject. It is thus a relation between a bearer of meaning (the subject) and a meaning (the predicate).
However, this relationship occurs within the frame of another relationship that occurs in the same intentional field. It is the relation (entirely unlike that of subject and predicate) between subject and object. Despite their difference, subject-predicate and subject-object relations cannot be separated but only distinguished. In effect, when the thought passes from the subject to the predicate, it does not consider the predicate (that is to say, it does not think about grammar) but its content, that is, the object or, rather, something that acquires the status of an object. The subject thus objectifies the target of though by means of predication. In the case of philosophy, that is to say, thinking about thinking, thought passes to something else, to what is being thought about, namely the object. And what is an object if not something that stands in front of the subject as a correlative to the subject? Hegel indeed argued that the object possesses nothing more than this relational character. The object is thus what was thought about by the subject. It is the entire universe existing insofar as it is the content of thought. There is no other universe. However, it is not the thought of my individual reflection. It is ultimately a universal reflection, and Hegel goes so far as to maintain that everything is Spirit (“There is nothing at hand that is wholly alien to spirit” (Hegel, Encyclopedia § 377, note, quoted by Duque, 38).
The Spirit is the objectification of subjectivity, the whole universe as thought of, a conceptualized universe, insofar as another does not replace it. But if something else remains, it is the task of thought to appropriate it, that is, as we said, to conceptualize it and thus imbue it with reality. This, in turn, is the secret of the coincidence of logic and metaphysics.
Thus, it turns out that the object is the complete expression of the subject. A strange reflection indeed. Fully aware of being a reflection and its denial at the same time—because it always returns to thinking about the object when it is supposed to be thinking about thinking about the object.
Hegel nonetheless moves backward. He rethinks the thought, concentrating not on content but on the fact of thinking about it. Hegel and his readers believed that they were thinking about Being when they were actually thinking about Essence; they thought they were thinking about Essence, and they were actually thinking about Concept! That is to say, Hegel was not concerned with a question of being but with the concept of being. It was not a question of essence but of the concept of essence, and it was not about concept but about the concept of concept. Hegel and his readers believed that they were thinking about substance when they were actually thinking about themselves—about the subject. Duque is therefore right in saying that all this does not mean we are solely concerned with thinking about substance, but also about the subject. This is because the substance is not even the truth, although it is a reflection, but this is a reflection that lacks reflection, or that does not know that it is a reflection. In other words, we are ultimately concerned with a subject thinking about itself.
The culmination of this backwards-advancing reflection is the Absolute Idea, which also serves as the culmination of subjectivity in the Subjective Logic (the third and last part of the Science of Logic). This must not be forgotten, as must the assertion that Hegel’s thought cannot migrate to another sphere, or does not enter it because Hegel does not need it, although he promises to explain something new, viz. the content of the Absolute Idea. But it is precisely here, at the end of the Science of Logic, that Hegel begins being poetic and stops being philosophical: he offers pure promises without any fulfillment. Such is the end of the great Science of Logic despite its colossality. Duque, in turn, ascribes a great deal of importance to this abrupt end in Hegel’s Logic. When the Absolute Idea is reached, according to Duque, “Everything else [Alles Übrige] is error, obscurity, struggle, caprice, and transience [Vergänglichkeit].” (Hegel, Science of Logic, quoted by Duque, 38). Is it not the case that everything should be included in the Absolute Spirit? Is the whole path unnecessary, as is the case of the ladder for the young Wittgenstein? This would go against the spirit of Hegel’s philosophy no less than his own assertion about error, obscurity, etc.
The Absolute Idea, then, does not fulfill Hegel’s intention. The universal absolute should deduce the individual in her or his singularity from itself because the individual is absolutely relational. It is a being that includes what is not her or him in itself, as well as what is other than itself, as the determinant of what it is. In other words, it is a concrete individuality understandable in its concrete universality. This is especially apparent when we think of the individual as a social being. If we take away all of the individual’s “environment” and context, namely, every socially shared issue and every general feature including language and clothing it will remain, contrary to what could be expected, an abstract individual: Just as when attempting to isolate the individual in order to understand it in her or his singularity, nothing remains and the very individual disappears. This, in turn, means that individuals are wholly social, that is, totally relational. This does not, however, imply that the individual is not individual, but that this is what it consists of: The more singular the individual, the more dependent she or he is on her or his network of relationships. Thus, the more relationships the individual has, the more individual she or he becomes.
When the individual denies her or his otherness, as in the case of the worker or the slave in Hegel’s Phenomenology of Spirit, she or he not only denies the other but it denies her or himself when alienating her or himself from her or his other because that other is her or his own other, not an abstract, isolated other. Thus, the more she or he is social, the more individual she or he becomes. The more she or he has relations to and dependencies on other individuals, the more she or he is a concrete singularity, a singularity determined by its relationships. This is entirely unlike the Aristotelian relations of genera and species, where the individual is obtained through isolation. The Aristotelian individual is obtained by excluding all difference. In Hegel the opposite is true: the more a thing includes the differentiated as differentiated in itself, the more individual it becomes. History is thus a process of socialization which is – in actual fact – a process of individuation. In Aristotelian logic, intension and extension are opposed: the greater the intension, the smaller the extension; the greater the definition, the smaller the subsumed individual(s). In Hegel, there is no such opposition. The individual is more social the more determined she or he is and the more she or he includes the other. Hegelian logic is not, however, intended as an alternative logic to Aristotelian logic, but rather as the self-consciousness of the Aristotelian logic as well as its inner development and evolution. Formal logic is thus a stage that the spirit must pass through in order to be finally be criticized by consciousness, as it is in the Logic of Essence, the second part of the Science of Logic, which engages in the critique of the “laws” of identity, non-contradiction, and the excluded middle.
I will now turn to the relationships between substance and subject. According to Aristotle, a substance is that which is neither said of a subject nor in a subject, namely, it is not a predicate as predicates are said about a substance (individuals, like this individual man or this statue). However, entities which say what a substance is are “secondary” substances, genera and species, that can be also subjects as well as predicates and are always general and never individual. However, saying what an individual is, has the genera and species as an answer, something that is not individual. The individual man belongs to a species, man, and an animal is a genus of that species. Thus, both man and animal are considered secondary substances. In this respect, Duque rightfully claims that the Aristotelian definition of substance as a negative definition arises from the impossibility of saying what it is without making it into something other than what it is. In other words, predicates will always betray their original intention since they cannot be individuals.
If there is something that is neither said of a subject nor exists in a subject, this is obviously because it is itself the subject, as Aristotle himself concedes: “All the other things are either said of the primary substances as subjects or in them as subjects” (Aristotle, Categories, 2a, 34–35, quoted by Duque, 6). Duque then proceeds to state:
Yet secondary substance does not exist of itself, unless it is given with primary substance. We are evidently confronted with a certain inversion here, with an irresolvable chiasmus: that which is first in the order of being is second in the order of logical discourse, and vice versa.” (Duque, 7)
The substance is for Aristotle the being of the being, and it is the fixed (permanent) side of change, something that does not change as things change. As a being of being it has a double function, meaning that it has two meanings in the sense that it is both the essence of the being and the being of the essence.
As the essence of being, the substance is the determinate being, the nature of the necessary being: the man as a two-legged animal. As the being of the essence it is the two-legged animal as this individual man.
This is a duality that Aristotle did not manage to resolve. When Aristotle says that the substance is expressed in the definition and that only the substance has a true definition, the substance is understood as the essence of the being, as that which reason can understand. But when, on the contrary, he declares that the essence is identical to determinate reality, as beauty exists only in what is beauty, Aristotle understands the substance as the being of the essence, and as a principle that offers necessary existence to the nature of a thing.
As the essence of being, the substance is the form of things and bestows unity on the elements that make up the whole where the whole is a distinct proper nature unlike its component elements. Aristotle refers to the form of material things as a species, and species is, therefore, its substance. As the being of the essence, the substance is the substrate: that about which any other thing is predicated but that cannot be a predicate of anything else. And as the substrate it is matter, a reality without any determination other than a potentiality. As the essence of being, the substance is the concept or logos that has neither generation nor corruption, that does not become but is this or that thing. As the being of essence, the substance is the composition, namely, the unity of concept (or form) with matter—the existing thing. In this sense, the substance comes to being and comes to its end.
As the essence of being, the substance is the principle of intelligibility of the being itself. In this sense, it is the stable and necessary element on which science is founded. According to Aristotle, there is no other science than that which is necessary, whereas the knowledge of what can or cannot be is rather an opinion. Substance is thus, objectively, the being of the essence and the necessary reality, and subjectively the essence of being, as necessary rationality. In short, the distinction Aristotle makes between primary substances (0ρώται οὐσίαι) and secondary substances (δεύτεραι οὐσίαι) consists of understanding the former as physical individuals and the latter as species (τά εἴδεα) and genera (τά γένη) of those individuals (Aristotle, Categories, 2a14).
In Hegel, on the other hand, the substance is the principle from which the individual is deduced. He argues for the primacy of the universal and the primacy of substance over the individual. Unlike with Aristotle, the universal is the principle of individuation, so that the individual has no meaning without the universal. This, in turn, is the basis on which his understanding of truth as substance but also as subject can be understood. Duque contends that “primary substance is entirely subsumed in secondary substance, or in universality. But this universality is indeed concrete since it bears and holds all particularity and all individuality within itself. It is concrete, but it does not yet know that it is.” (Duque, 2018, 24). Namely, it doesn’t know that it is also a subject.
The intentional character of the subject, as it is understood in self-consciousness, means the understanding of the subject as the one that externalizes itself and then internalizes what was rejected, that is, that understands that this is its way of acting. It also means that being is ultimately recognized in reflection as a first instance, that is, as thinking. Substance is itself thinking, though not recognized as such. Ultimately, therefore, subject is a synthesis of self-consciousness and objectivity.
In judgment, when the subject moves toward the predicate, when it is objectified and when, in subsequent reflection, discovers that it returns to itself (since the predicate is predicated from the subject), then the subject ends up enriched with what the predicate attributes to it.
This, in turn, allows us to understand the controversial and somehow obscure dictum in the 1806 preface to the Phenomenology of Spirit:
According to my view of things, which can be justified through the exposition of the system itself, everything depends on apprehending and expressing the true not as [nicht als] substance, but just as much [eben so sehr] as subject (quoted by Duque, 17)
Hegel therefore contends that self-consciousness is externalized and thus becomes an object. But this posited object is itself the very subject that has been placed as another, thus appearing as an opposite to itself: it knows itself knowing the other.
And this happens because that object is not, as it were, a natural object, a given, but an object created or engendered (like any object, according to Hegel) by self-consciousness. They are, then, two momenta, that of subjectivity (being-for-itself) and that of objectivity (being-in-itself). In reality, however, they are not merely two momenta, but a single reality split into two momenta that are only true in their opposition and in their unity. For subjectivity does not become true if it is not objective and true objectivity cannot be natural but only produced by human endeavor (in the broad sense of the word). This is why the fact that men, at one point in history, had subjected other men to work, to externalize themselves, to produce objects out of themselves, and thus transform a given natural environment into a human environment, is a necessary step in human development, as this is a human creation, an elevation above the natural.
A misreading, according to Duque, is to believe that the substance is not true as if the subject has nothing to do with the substance (or mutatis mutandis, a misreading that believes that freedom has nothing to do with necessity). Just as reason does not exist without understanding, subject does not exist without substance. The subject is thus the conceptual understanding of the substance and the consciousness of necessity. Put differently, it is a continuation of Spinozism taken to its logical extreme.
