The Employment in Natural Philosophy of Metaphysics Combined with Geometry, of Which Sample I Contains the Physical Monadology

Immanuel Kant's dissertation, The Employment in Natural Philosophy of Metaphysics Combined with Geometry, of Which Sample I Contains the Physical Monadology (1756), explored how metaphysical concepts and geometry could be applied to natural philosophy. This work contrasted Newtonian scientific methods with the prevailing rationalist philosophy of Gottfried Wilhelm Leibniz and Christian Wolff.1

Kant proposed a "physical monadology," suggesting that the universe is composed of fundamental, indivisible substances called monads. These monads, though lacking extension, were seen as dynamic entities reflecting the order of the world. This dissertation was an early step in Kant's philosophical development, laying groundwork for his later critical philosophy, which would fundamentally alter the understanding of metaphysics and the limits of human knowledge.12345
