This chapter examines Georg Wilhelm Friedrich Hegel’s concept of quantitative relation which he explains in detail in his Science of Logic. It begins with an overview of Hegel’s treatment of quantity in relation to quality, as well as his account of essence or substance. Drawing on the earlier work of John Locke and Johann Gottlieb Fichte, it discusses Hegel’s analysis of reflection. It considers Fichte’s Wissenschaftslehre or Doctrine of Science (1794), with emphasis on his interpretation of the three laws of thought: identity, difference, and the ground—his version of the law of noncontradiction. The chapter concludes by citing defects in the Fichtean formulation of reflection from a Hegelian perspective.
