Extension in Leibniz

This article studies the stages in which Leibniz’s thoughts had been shaped about extension and place, and their interrelation. It shows how Leibniz considers “kraft-virtus-vis” to be the base of all things and extension, by rejecting any substance for extension. By going out of the Cartesian and Kantian dualism, he suggests a spiritual base for worldly entities. Leibniz assumes extension, matter, and place as phenomenal levels and derivative realities, and therefore, considers the world to be infinite on both sides (from within and from without). Hence, he rejects atom and void. He considers the base of things as metaphysical points called, “monads”, which have life and understanding, and have a comprehension of their environment. In this way he also explains the nature of connection.
