Life and Works
Kant's favorite teacher was Martin Knutzen (1713–1751), a Pietist who was heavily influenced by both Wolff and the English philosopher John Locke (1632–1704).
Knutzen introduced Kant to the work of Isaac Newton (1642–1727), and his influence is visible in Kant's first published work, Thoughts on the True Estimation of Living Forces (1747), which was a critical attempt to mediate a dispute in natural philosophy between Leibnizians and Newtonians over the proper measurement of force.
