Immanuel Kant
Kant developed his moral philosophy in three works: "Groundwork of the Metaphysic of Morals" (1785), "Critique of Practical Reason" (1788), and "Metaphysics of Morals" (1797).
Émilie du Châtelet
Immanuel Kant's first publication in 1747 'Gedanken zur wahren Schätzung der lebendigen Kräfte' focuses on Du Châtelet's pamphlet against the secretary of the French Academy of Sciences, Mairan. Kant's opponent, Johann Augustus Eberhard accused Kant of taking ideas from Du Châtelet.
