Immanuel Kant
German philosopher Immanuel Kant surrounded by Ouroboros, an emblematic serpent of ancient Egypt and Greece, engraving by John Chapman, published in London, 1812.
Sir Isaac Newton exerted a profound influence on Immanuel Kant’s early scientific and philosophical development, primarily by providing a model of empirical inquiry that challenged the prevailing rationalist systems of his time.12
- Scientific Inspiration: During his university years, Kant was introduced to Newtonian science by a professor who was an enthusiast of the English physicist. This sparked Kant’s interest in physics and mathematics, leading him to write his first book on kinetic forces in 1746.1
- Methodological Contrast: As a lecturer, Kant used Newtonian physics to contrast the empirical, inductive methods of science with the abstract, rationalistic philosophy of Gottfried Wilhelm Leibniz and Christian Wolff, which then dominated German universities.2
- Philosophical Shift: Kant eventually adopted a pro-Newtonian stance, siding with Newton against Leibniz regarding the nature of space. His study of Newton reinforced his conviction that a purely synthetic philosophy—one attempting to construct truths from self-evident premises—was empty and false. This shift helped move Kant away from "dogmatic" rationalism toward his later critical philosophy.3
