"Gottfried Wilhelm Leibniz (1646 - 1716) was one of the great thinkers of the seventeenth and eighteenth centuries and is known as the last “universal genius”. His contributions in the fields of metaphysics, epistemology, logic, philosophy of religion, as well as mathematics, physics, geology, jurisprudence, and history are revolutionary.
It was only in the 20th century that Leibniz's law of continuity and transcendental law of homogeneity found mathematical implementation. Further, he also made major contributions to physics and technology, though his anticipated notions surfaced much later in philosophy, probability theory, biology, and medicine.
Leibniz faced much criticism during his final years. He was engaged in a bitter debate with Newton over the priority of the discovery of the calculus, and was accused of stealing Newton's ideas. It was much later that mathematicians started to acknowledge that Leibnitz and Newton had developed individual ideas. Leibniz passed away on November 14, 1716.
