This chapter presents the general argument of the book and its main methodological assumptions. The book offers a close reading of the examination of the concept of purpose in The Science of Logic. The concept is understood abstractly, but nevertheless as a causal concept, by means of which we think about what the intrinsic reference to an end means and implies. The chapter clarifies in what sense the approach developed in this book is metaphysical and also what the importance of a better appreciation of Hegel’s chapter on this concept for a correct understanding of the goals and, particularly, the achievements of his entire Science of Logic is.
