Remembered mainly as a logician and mathematician, Leibniz also endeavored to resolve political and religious conflicts of his day by bringing opponents into negotiation. The dialectical Leibniz who emerges from the texts here translated, commented, and interpreted is certainly not the familiar one. The book sheds new light on the familiar, yet incomplete image of Leibniz, providing further reason for cherishing and cultivating the heritage of a truly great man.
