Abstract
IT IS WELL KNOWN THAT LEIBNIZ’S NOTION OF HARMONY plays a crucial role in his philosophical system. Leibniz drew on this concept of harmony in motivating, and explaining, numerous areas of his thought: everything from Leibnizian mathematics and metaphysics to ethics and social philosophy, incorporates the notion of harmony as a central descriptive and explanatory concept. While there has been much discussion of some the applications of harmony in Leibniz’s system– especially the mind-body harmony, and the so-called universal harmony of simple perceiving substances–little attention has been paid to Leibniz’s very concept of harmony. Yet it seems important for understanding Leibniz’s holistic philosophy that we grasp this concept, for he employed the term “harmony” when describing so many features of the created world: there is a harmony between geometry and physics, between efficient and final causation, between nature and grace, to mention just a few.
