Hegel's philosophical system is divided into three parts: the science of
logic,
the philosophy of nature, and the philosophy of
spirit (the latter two of which together constitute the
real philosophy). This structure is adopted from
Proclus's
Neoplatonic triad of remaining-procession-return' and from the Christian Trinity." Although evident in draft writings dating back as early as 1805, the system was not completed in published form until the 1817
Encyclopedia (1st ed.). Historian of philosophy
Frederick C. Beiser argues that the position of the logic with respect to the real philosophy is best understood in terms of Hegel's appropriation of Aristotle's distinction between "the order of explanation" and "the order of being." To Beiser, Hegel is neither a Platonist who believes in abstract logical entities, nor a
nominalist according to whom the particular is first in the orders of explanation and being alike. Rather, Hegel is a
holist. For Hegel, the universal is always first in the order of explanation even if what is naturally particular is first in the order of being. With respect to the system as a whole, that universal is supplied by the logic. Scholar
Michael J. Inwood states, "The logical idea is non-temporal and therefore does not exist at any time apart from its manifestations." To ask "when" it divides into nature and spirit is analogous to asking "when" 12 divides into 5 and 7. The question does not have an answer because it is predicated upon a fundamental misunderstanding of its terms. The task of the logic (at this high systemic level) is to articulate what Hegel calls "the identity of identity and non-identity" of nature and spirit. Put another way, it aims to overcome subject–object dualism. This is to say that, among other things, Hegel's philosophical project endeavors to provide the metaphysical basis for an account of spirit that is continuous with, yet distinct from, the "merely" natural world – without thereby reducing either term to the other. Furthermore, the final sections of Hegel's
Encyclopedia suggest that to give priority to any one of its three parts is to have an interpretation that is "one-sided," incomplete or otherwise inaccurate. As Hegel declares, "The true is the whole."
Science of Logic Hegel's concept of logic differs greatly from that of the ordinary English sense of the term. This can be seen, for instance, in such metaphysical definitions of logic as "the science of
things grasped in [the]
thoughts that used to be taken to express the
essentialities of the
things." As
Michael Wolff explains, Hegel's logic is a continuation of Kant's distinctive logical program. Its occasional engagement with the familiar
Aristotelian conception of logic is only incidental to Hegel's project. Twentieth-century developments by such logicians as
Frege and
Russell likewise remain logics of formal validity and so are likewise irrelevant to Hegel's project, which aspires to provide a metaphysical logic of truth. There are two texts of Hegel's
Logic. The first,
The Science of Logic (1812, 1813, 1816; Book I revised 1831), is sometimes also called the "Greater Logic." The second is the first volume of Hegel's
Encyclopedia and is sometimes known as the "Lesser Logic." The
Encyclopedia Logic is an abbreviated or condensed presentation of the same dialectic. Hegel composed it for use with students in the lecture hall, not as a substitute for its proper, book-length exposition. Hegel presents logic as a presuppositionless science that investigates the most fundamental thought-determinations [
Denkbestimmungen], or
categories, and so constitutes the basis of philosophy. In putting something into question, one already presupposes logic; in this regard, it is the only field of inquiry that must constantly reflect upon its own mode of functioning.
The Science of Logic is Hegel's attempt to meet this foundational demand. As he puts it, "
logic coincides with
metaphysics." In the words of scholar Glenn Alexander Magee, the logic provides "an account of pure categories or ideas which are timelessly true" and which make up "the formal structure of reality itself". This is not, however, a return to the
Leibnizian–
Wolffian rationalism critiqued by Kant, which is a criticism Hegel accepts. Hegel rejects any form of metaphysics as speculation about the transcendent. His procedure, an appropriation of Aristotle's concept of
form, is fully immanent. More generally, Hegel agrees with Kant's rejection of all forms of dogmatism and also agrees that any future metaphysics must pass the test of criticism. Philosopher
Béatrice Longuenesse holds that this project may be understood, on analogy to Kant, as "inseparably a metaphysical and a transcendental deduction of the categories of metaphysics." This approach insists, and claims to demonstrate, that the insights of logic cannot be judged by standards external to thought itself, that is, that "thought... is not the mirror of nature." Yet, she argues, this does not imply that these standards are arbitrary or subjective. Hegel's translator and scholar of
German idealism George di Giovanni likewise interprets the
Logic as (drawing upon, yet also in opposition to,
Kant)
immanently transcendental; its categories, according to Hegel, are built into
life itself, and define what it is to be "an object in general." Books one and two of the
Logic are the doctrines of "Being" and "Essence." Together they comprise the Objective Logic, which is largely occupied with overcoming the assumptions of traditional metaphysics. Book three is the final part of the
Logic. It discusses the doctrine of "the Concept," which is concerned with reintegrating those categories of objectivity into a thoroughly
idealistic account of reality. Simplifying greatly, Being describes its concepts just as they appear, Essence attempts to explain them with reference to opposites, and the Concept explains and unites them both in terms of an internal teleology. The categories of Being "pass over" from one to the next as denoting thought-determinations only extrinsically connected to one another. The categories of Essence reciprocally "shine" into one another. Finally, in the Concept, thought has shown itself to be fully self-referential, and so its categories organically "develop" from one to the next. In Hegel's technical sense of the term, the concept (
Begriff, sometimes also rendered "notion," capitalized by some translators but not others) is not a psychological concept. When deployed with the definitive article ("the") and sometimes modified by the term "logical," Hegel is referring to the intelligible structure of reality as articulated in the Subjective Logic. (When used in the plural, however, Hegel's sense is much closer to the ordinary dictionary sense of the term.) Hegel's inquiry into thought is concerned to systematize thought's own internal self-differentiation, that is, how pure concepts (
logical categories) differ from one another in their various relations of implication and interdependence. For instance, in the opening dialectic of the
Logic, Hegel claims to display that the thought of "
being, pure being – without further determination" is indistinguishable from the concept of
nothing, and that, in this "passing back and forth" of being and nothing, "
each immediately
vanishes in its opposite." This movement is neither one concept nor the other, but the category of
becoming. There is not a difference here to which one can "refer," only a dialectic that one can observe and describe. The final category of the
Logic is "the idea." As with "the concept", the sense of this term for Hegel is not psychological. Rather, following
Kant in
The Critique of Pure Reason, Hegel's usage harks back to the Greek
eidos,
Plato's concept of
form that is fully existent and universal: "Hegel's
Idee (like Plato's idea) is the product of an attempt to fuse ontology, epistemology, evaluation, etc., into a single set of concepts." The
Logic accommodates within itself the necessity of the realm of natural-spiritual
contingency, that which cannot be determined in advance: "To go further, it must abandon thinking altogether and let itself go, opening itself to that which is other than thought in pure receptivity." Simply put, logic realizes itself only in the domain of nature and spirit, in which it attains its "verification." Hence the conclusion of the
Science of Logic with "the idea
freely discharging [entläßt] itself" into "objectivity and external life" – and, so too, the systematic transition to the
Realphilosophie.
Philosophy of the real as a metaphor for how philosophy can understand historical conditions only after they occur. In contrast to the first, logical part of Hegel's system, the second,
real-philosophical part – the philosophy of nature and of spirit – is an ongoing project with respect to its historical content, which continues to change and develop. For instance, although Hegel regards "the basic structure" of the philosophy of nature as complete, he was "aware that science is not 'finished' and will continue to make new discoveries". Philosophy is, as Hegel puts it, "
its own time comprehended in thoughts." He expands upon this definition: A further word on the subject of
issuing instructions on how the world ought to be: philosophy, at any rate, always comes too late to perform this function. As the
thought of the world, it appears only at a time when actuality has gone through its formative process and attained its completed state [
sich fertig gemacht]. This lesson of the concept is necessarily also apparent from history, namely that it is only when actuality [
Wirklichkeit] has reached maturity that the ideal appears opposite the real and reconstructs this real world, which it has grasped in its substance, in the shape of an intellectual realm. When philosophy paints its gray in gray, a shape of life has grown old, and it cannot be rejuvenated, but only recognized, by the gray in gray of philosophy; the owl of
Minerva begins its flight only with the onset of dusk. This frequently has been read as an expression of the impotence of philosophy, political or otherwise, and a rationalization of the status quo. Scholar
Allegra de Laurentiis, however, points out that the German expression "
sich fertig machen", translated as "getting ready" or "to get ready", does not only imply completion, but also preparedness. This additional meaning is important because it better reflects Hegel's
Aristotelian concept of
actuality. He characterizes actuality as being-at-work-staying-itself that can never be once-and-for-all completed or finished. Hegel describes the relationship between the logical and the real-philosophical parts of his system in this way: "If philosophy does not stand above its time in content, it does so in
form, because, as the thought and knowledge of that which is the substantial spirit of its time, it makes that spirit its object." This is to say that what makes the philosophy of the real
scientific in Hegel's technical sense is the systematically coherent logical form it uncovers in its natural-historical material – and so also displays in its presentation.
The Philosophy of Nature The
philosophy of nature organizes the contingent material of the natural sciences systematically. As part of the
philosophy of the real, in no way does it presume to "tell nature what it must be like." Historically, various interpreters have questioned Hegel's understanding of the natural sciences of his time. However, this claim has been largely refuted by recent scholarship. One of the very few ways in which the philosophy of nature might correct claims made by the natural sciences themselves is to combat reductive explanations; that is, to discredit accounts employing categories not adequate to the complexity of the phenomena they purport to explain, as for instance, attempting to explain life in strictly chemical terms. Although Hegel and other
Naturphilosophen aim to revive a teleological understanding of nature, they argue that their strictly
internal or
immanent concept of teleology is "limited to the ends observable within nature itself." Hence, they claim, it does not violate the Kantian critique. Even more strongly, Hegel and Schelling claim that Kant's restriction of teleology to regulative status effectively undermines his own critical project of explaining the possibility of knowledge. Their argument is that "only under the assumption that
there is an organism is it possible to explain the
actual interaction between the subjective and the objective, the ideal and the real." Hence, the organism must be acknowledged to have constitutive status. Introducing Hegel's philosophy of nature for a 21st-century audience, observes that "contemporary philosophy of science" has lost sight of "the ontological issue at stake, namely, the question of an intrinsically lawful nature": "Consider, for example, the problem of what constitutes a law of nature. This problem is central to our understanding of nature. Yet philosophy of science has not provided a definitive response to it up to now. Nor can we expect to have such an answer from that quarter in future." It is back to Hegel that Wandschneider would direct
philosophers of science for guidance in the
philosophy of nature. Recent scholars have also argued that Hegel's approach to the philosophy of nature provides valuable resources for theorizing and confronting recent environmental challenges entirely unforeseen by Hegel. These philosophers point to such aspects of his philosophy as its distinctive metaphysical grounding and the continuity of its conception of the nature-spirit relationship.
The Philosophy of Spirit . The Delphic imperative to "know thyself" governs Hegel's entire philosophy of spirit. The German
Geist has a wide range of meanings. In its most general Hegelian sense, however, "
Geist denotes the human mind and its products, in contrast to nature and also the logical idea." (Some older translations render it as "mind," rather than "spirit.") As is especially evident in the Anthropology, Hegel's concept of spirit is an appropriation and transformation of the self-referential Aristotelian concept of
energeia. Spirit is not something above or otherwise external to nature. It is "the highest organization and development" of nature's powers. According to Hegel, "the
essence of spirit is
freedom." The
Encyclopedia Philosophy of Spirit charts the progressively determinate stages of this freedom until spirit fulfills the
Delphic imperative with which Hegel begins: "
Know thyself." As becomes clear, Hegel's concept of freedom is not (or not merely) the capacity for arbitrary choice, but has as its "core notion" that "something, especially a person, is free if and only if, it is independent and self-determining, not determined by or dependent upon something other than itself." It is, in other words, (at least predominantly, dialectically) an account of what
Isaiah Berlin would later term
positive liberty.
Subjective spirit Standing at the transition from nature to spirit, the role of the Philosophy of Subjective Spirit is to analyze "the elements necessary for or presupposed by such relations [of objective spirit], namely, the structures characteristic of and necessary to the individual rational agent." It does this by elaborating "the fundamental nature of the biological/spiritual human individual along with the cognitive and the practical prerequisites of human social interaction." This section, particularly its first part, contains various comments that were commonplace in Hegel's day and can now be recognized as openly racist, such as unfounded claims about the "naturally" lower intellectual and emotional development of Black people. In his perspective, these racial differences are related to
climate: according to Hegel, it is not racial characteristics, but the climactic conditions in which a people lives that variously limit or enable its capacity for free self-determination. He believes that race is not destiny: any group could, in principle, improve and transform its condition by migrating to friendlier climes. Hegel divides his philosophy of the subjective spirit into three parts: anthropology, phenomenology, and psychology. Anthropology "deals with 'soul', which is spirit still mired in nature: all that within us which precedes our self-conscious mind or intellect." In the section "Phenomenology", Hegel examines the relation between consciousness and its object and the emergence of intersubjective rationality. Psychology "deals with a great deal that would be categorized as epistemology (or 'theory of knowledge') today. Hegel discusses, among other things, the nature of attention, memory, imagination and judgement." Throughout this section, but especially in the Anthropology, Hegel appropriates and develops
Aristotle's
hylomorphic approach to what is today theorized as the
mind–body problem: "The solution to the mind–body problem [according to this theory] hinges upon recognizing that mind does not act upon the body as cause of effects but rather acts upon itself as an embodied living subjectivity. As such, mind develops itself, progressively attaining more and more of a self-determined character." Its final section, Free Spirit, develops the concept of "free will", which is foundational for Hegel's philosophy of right.
Objective spirit (1797–1840) stifled the political reforms for which Hegel had hoped and advocated. In the broadest terms, Hegel's philosophy of objective spirit "is his social philosophy, his philosophy of how the human spirit objectifies itself in its social and historical activities and productions." Or, put differently, it is an account of the institutionalization of freedom. Besier declares this a rare instance of unanimity in Hegel scholarship: "all scholars agree there is no more important concept in Hegel's political theory than freedom." This is because it is the foundation of right, the essence of spirit, and the
telos of history. This part of Hegel's philosophy is presented first in his 1817
Encyclopedia (revised 1827 and 1830) and then at greater length in the 1821
Elements of the Philosophy of Right, or Natural Law and Political Science in Outline (like the
Encyclopedia, intended as a textbook), upon which he also frequently lectured. Its final part, the philosophy of world history, was additionally elaborated in
Hegel's lectures on the subject. Hegel's
Elements of the Philosophy of Right has been controversial from the date of its original publication. It is not, however, a straightforward defense of the autocratic Prussian state, as some have alleged, but is rather a defense of "Prussia as it was to have become under [proposed] reform administrations." The German
Recht in Hegel's title does not have a direct English equivalent (though it does correspond to the Latin
ius and the French
droit). As a first approximation, Michael Inwood distinguishes three senses: • a right, claim or title • justice (as in, e.g., 'to administer justice'...but not justice as a virtue...) • 'the law' as a principle, or 'the laws' collectively. Beiser observes that Hegel's theory is "his attempt to rehabilitate the
natural law tradition while taking into account the criticisms of the historical school." He adds that "without a sound interpretation of Hegel's theory of natural law, we have very little understanding of the very foundation of his social and political thought." Consistent with Beiser's position, scholar
Adriaan T. Peperzak documents Hegel's arguments against
social contract theory and stresses the metaphysical foundations of Hegel's philosophy of right. Observing that "analyzing the structure of Hegel's argument in the
Philosophy of Right shows that achieving political autonomy is fundamental to Hegel's analysis of the state and government," philosopher
Kenneth R. Westphal provides this brief outline: • Abstract Right,' treats principles governing property, its transfer, and wrongs against property." • Morality,' treats the rights of moral subjects, responsibility for one's actions, and
a priori theories of right." •
Ethical Life' (Sittlichkeit), analyzes the principles and institutions governing central aspects of rational social life, including the family,
civil society, and the
state as a whole, including the government." Hegel describes the state of his time, a
constitutional monarchy, as rationally embodying three cooperative and mutually inclusive elements. These elements are "democracy (rule of the many, who are involved in legislation),
aristocracy (rule of the few, who apply, concretize, and execute the laws), and monarchy (rule of the one, who heads and encompasses all power)." It is what Aristotle called a "mixed" form of government, which is designed to include what is best of each of the three classical forms. The division of powers "prevents a single power from dominating others." Hegel is particularly concerned to bind the monarch to the constitution, limiting his authority so that he can do little more than to declare of what his ministers have already decided that it is to be so. The relation of Hegel's philosophy of right to modern liberalism is complex. He sees liberalism as a valuable and characteristic expression of the modern world. However, it carries the danger within itself to undermine its own values. This self-destructive tendency may be avoided by measuring "the subjective goals of individuals by a larger objective and collective good." Moral values, then, have only a "limited place in the total scheme of things." Yet, although it is not without reason that Hegel is widely regarded as a major proponent of what
Isaiah Berlin would later term
positive liberty, he was just as "unwavering and unequivocal" in his defense of
negative liberty. If Hegel's ideal sovereign is much weaker than was typical in monarchies his time, so too is his democratic element much weaker than is typical in democracies of modern times. Although he insists upon the importance of public participation, Hegel severely limits suffrage and follows the English
bicameral model, in which only members of the lower house, that of commoners and
bourgeoisie, are elected officials. Nobles in the upper house, like the monarch, inherit their positions. The final part of the Philosophy of Objective Spirit is entitled "World History." In this section, Hegel argues that "this immanent principle [the
Stoic logos] produces with logical inevitability an expansion of the species' capacities for self determination ('freedom') and a deepening of its self understanding ('self-knowing')." In Hegel's own words: "World history is progress in the consciousness of freedom – a progress that we must comprehend conceptually."
Absolute spirit ) Hegel's use of the term "absolute" is easily misunderstood. Inwood, however, clarifies: derived from the Latin
absolutus, it means "not dependent on, conditional on, relative to or restricted by anything else; self-contained, perfect, complete." For Hegel, this means that absolute knowing can only denote "an 'absolute relation' in which the ground of experience and the experiencing agent are one and the same: the object known is explicitly the subject who knows." That is, the only "thing" (which is really an activity) that is truly absolute is that which is entirely self-conditioned, and, according to Hegel, this only occurs when spirit takes itself up as its own object. The final section of his Philosophy of Spirit presents the three modes of such absolute knowing: art, religion, and philosophy. It is with reference to different modalities of consciousness –
intuition, representation, and comprehending thinking – that Hegel distinguishes the three modes of absolute knowing.
Frederick Beiser summarizes: "art, religion and philosophy all have the same object, the absolute or truth itself; but they consist in different forms of knowledge of it. Art presents the absolute in the form of immediate intuition (
Anschauung); religion presents it in the form of representation (
Vorstellung); and philosophy presents it in the form of concepts (
Begriffe)." The German philosopher
Rüdiger Bubner additionally clarifies that the increase in conceptual transparency according to which these spheres are systematically ordered is not hierarchical in any evaluative sense. Although Hegel's discussion of absolute spirit in the
Encyclopedia is quite brief, he develops his account at length in
lectures on the philosophy of fine art,
the philosophy of religion, and
the history of philosophy. == Philosophy of art ==
