Science of Logic (German: Wissenschaft der Logik), first published between 1812 and 1816, is the work in which Georg Wilhelm Friedrich Hegel outlined his vision of logic. Hegel's logic is a system of dialectics, i.e., a dialectical metaphysics: it is a development of the principle that thought and being constitute a single and active unity. Science of Logic also incorporates the traditional Aristotelian syllogism: it is conceived as a phase of the "original unity of thought and being" rather than as a detached, formal instrument of inference.

For Hegel, the most important achievement of German idealism, starting with Immanuel Kant and culminating in his own philosophy, was the argument that reality (being) is shaped by thought and is, in a strong sense, identical to thought. Thus ultimately the structures of thought and being, subject and object, are identical. Since for Hegel the underlying structure of all of reality is ultimately rational, logic is not merely about reasoning or argument but rather is also the rational, structural core of all of reality and every dimension of it. Thus Hegel's Science of Logic includes among other things analyses of being, nothingness, becoming, existence, reality, essence, reflection, concept, and method.

Hegel considered it one of his major works and therefore kept it up to date through revision.

Science of Logic is sometimes referred to as the Greater Logic to distinguish it from the Lesser Logic, the moniker given to the condensed version Hegel presented as the "Logic" section of his Encyclopedia of the Philosophical Sciences.

## Publication history

[edit]

Hegel wrote Science of Logic after he had completed his Phenomenology of Spirit and while he was in Nuremberg working at a secondary school and courting his fiancée. It was published in two volumes. The first, ‘The Objective Logic’, has two parts (the Doctrines of Being and Essence) and each part was published in 1812 and 1813 respectively. The second volume, ‘The Subjective Logic’, was published in 1816 the same year he became a professor of philosophy at Heidelberg. Science of Logic is too advanced for undergraduate students so Hegel wrote an Encyclopaedic version of the logic which was published in 1817 and expanded in 1827 with additional revisions in 1831.

In 1826, Science of Logic went out of stock. Instead of reprinting, as requested, Hegel undertook some revisions. By 1831, Hegel completed a greatly revised and expanded version of the "Doctrine of Being", but had no time to revise the rest of the book. The Preface to the second edition is dated 7 November 1831, just before his death on 14 November 1831. This edition appeared in 1832, and again in 1834–5 in the posthumous Works. Only the second edition of Science of Logic is translated into English.

## Hegel's general concept of logic

[edit]

According to Hegel, logic is the form taken by the science of thinking in general. He thought that, as it had hitherto been practiced, this science demanded a total and radical reformulation "from a higher standpoint." At the end of the preface he wrote that "Logic is the thinking of God". His stated goal with The Science of Logic was to overcome what he perceived to be a common flaw running through all other former systems of logic, namely that they all presupposed a complete separation between the content of cognition (the world of objects, held to be entirely independent of thought for their existence), and the form of cognition (the thoughts about these objects, which by themselves are pliable, indeterminate and entirely dependent upon their conformity to the world of objects to be thought of as in any way true). This unbridgeable gap found within the science of reason was, in his view, a carryover from everyday, phenomenal, unphilosophical consciousness.[1]

The task of extinguishing this opposition within consciousness Hegel believed he had already accomplished in his book Phänomenologie des Geistes (1807) with the final attainment of Absolute Knowing: "Absolute knowing is the truth of every mode of consciousness because ... it is only in absolute knowing that the separation of the object from the certainty of itself is completely eliminated: truth is now equated with certainty and certainty with truth."[2] Once thus liberated from duality, the science of thinking no longer requires an object or a matter outside of itself to act as a touchstone for its truth, but rather takes the form of its own self-mediated exposition and development which eventually comprises within itself every possible mode of rational thinking. "It can therefore be said," says Hegel, "that this content is the exposition of God as he is in his eternal essence before the creation of nature and a finite mind."[3] The German word Hegel employed to denote this post-dualist form of consciousness was Begriff (traditionally translated either as Concept or Notion).

## General division of the Logic

[edit]

The self-exposition of the concept (also translated as notion), follows a series of necessary, self-determined stages in an inherently logical, dialectical progression. Its course is from the objective to the subjective "sides" (or judgements as Hegel calls them) of the concept. The objective side, its Being, is the concept as it is in itself [an sich], its reflection in nature being found in anything inorganic such as water or a rock. This is the subject of Book One: The Doctrine of Being. Book Three: The Doctrine of the concept outlines the subjective side of the concept as concept, or, the concept as it is for itself [für sich]; human beings, animals and plants being some of the shapes it takes in nature. The process of Being's transition to the concept as fully aware of itself is outlined in Book Two: The Doctrine of Essence, which is included in the Objective division of the Logic.[4] The initial main components of Volume Two are Hegel's theories of the judgment and syllogism under the heading of subjective. This is followed by his theory of objectivity (also under the heading of subjective) and finally he integrates these into his theory of the Idea. The Science of Logic is thus divided like this:

Volume One: The Objective Logic

Book One: The Doctrine of Being
Book Two: The Doctrine of Essence
Volume Two: The Subjective Logic

Book Three: The Doctrine of the Concept

This division, however, does not represent a strictly linear progression. At the end of the book Hegel wraps all of the preceding logical development into a single Absolute Idea. Hegel then links this final absolute idea with the simple concept of Being which he introduced at the start of the book. Hence the Science of Logic is actually a circle and there is no starting point or end, but rather a totality. This totality is itself, however, but a link in the chain of the three sciences of Logic, Nature and Spirit, as developed by Hegel in his Encyclopedia of the Philosophical Sciences (1817), that, when taken as a whole, comprise a "circle of circles."[5]
