English: Diagram representing the complicated arrangement found in Politics. First comes a general theory of constitutions, right and wrong (Books Α, Β, Γ); and this part is afterwards referred to as “the first discourses” (ἐν τοῖς πρώτοις λόγοις). Then follows the treatment of oligarchy, democracy, commonwealth and tyranny, and of the various powers of government (Δ), and independent investigation of revolution, and of the means of preserving states (Ε), and a further treatment of democracy and oligarchy, and of the different offices of the state (Ζ), and finally a return to the discussion of the right form of constitution (Η, Θ). But Δ and Ζ are a group interrupted by Ε, and Η and Θ are another group unconnected with the previous group and with Ε, and are also distinguished in style by avoiding hiatus. Further, the group (Δ, Ζ) and the group (Η, Θ) are both unfinished. Finally the group (Δ, Ζ), the book (Ε) and the group (Η, Θ) though unconnected with one another, are all connected though imperfectly with “the first discourses” (Α, Β, Γ).
