This chapter summarizes Georg Wilhelm Friedrich Hegel’s concept of quantity which he explains in detail in his Science of Logic. It first provides an overview of the general structure of book 1 of the Science of Logic and its discussion of the three levels of the structure of being, namely, determinateness or quality, magnitude or quantity, and measure. It ten examines Hegel’s account of the infinitesimal in early nineteenth-century versions of the calculus, the distinction between human time and the so-called transcendental activity of the absolute, quantity as a moment of the continuum, and the Hegelian notion of form. The chapter also considers Immanuel Kant’s understanding of the antinomies and Hegel’s insistence that Kant has not attained to dialectical logic. Finally, it analyzes quantum, “how much,” as a moment of quantity.
