 Christian Wolff (1679–1754) was a philosopher, mathematician, and scientist of the German Enlightenment. He is widely and rightly regarded as the most important and influential German philosopher between Leibniz and Kant. His scholarly output was prolific, numbering more than 50 (most multi-volume) titles, in addition to dozens of shorter essays and prefaces and nearly 500 book reviews. Through his series of textbooks, published first in German and then in Latin, Wolff made signal contributions to nearly every area of philosophical investigation of his time, including but not limited to logic, metaphysics, ethics, political philosophy, and aesthetics. Wolff is perhaps best known in his role as (co-)founder of the “Leibnizian-Wolffian philosophy”, and while Wolff himself rejected the term, the philosophical system it designates quickly gained broad, if not universal, acceptance within German universities in the first half of the eighteenth century.
