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. 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." ==Editions of
