In his critical exposition, John Dewey examines Gottfried Wilhelm Leibniz's masterpiece, *New Essays Concerning the Human Understanding*, arguing that it functions less as a connected argument and more as a rich compendium of comments. To fully grasp Leibniz's system, Dewey notes that one must supplement the *New Essays* with references to Leibniz's other writings. The text systematically contrasts Leibniz's rationalistic method with John Locke's empiricism, addressing pivotal issues such as innate ideas, the nature of sensation, the will, and the relationship between matter and spirit. Dewey elucidates Leibniz's core metaphysical doctrines, including monads, pre-established harmony, and the principle of sufficient reason. He explains how these concepts reconcile universal unity with individual activity, positing that all unity is spiritual and active. A central theme is the contrast between the British and German philosophical traditions; while Locke viewed consciousness and ideas through a mechanical lens, Leibniz offered an organic conception, introducing the theory of unconscious intelligence to refute Locke's denial of innate ideas. Dewey details how Leibniz's doctrine of pre-established harmony is not merely a coincidence of independent substances but a harmony between modes of knowing—specifically between sense and understanding. The exposition further explores Leibniz's theology and ethics, where he argues for God's existence through ontological, cosmological, and teleological proofs. Dewey highlights Leibniz's view that the ultimate foundation of all truths, whether mathematical or factual, lies in the divine intelligence. However, Dewey also identifies fundamental contradictions in Leibniz's thought, particularly between his method and his subject matter, contradictions that Immanuel Kant later addressed. Kant transformed Leibniz's vague notion of sufficient reason into a rigorous distinction between analytic and synthetic judgments, while reinterpreting pre-established harmony as a subjective unity within human intelligence rather than an objective arrangement of things. Despite these limitations, Dewey concludes that Leibniz's insights into organism, continuity, and the unity of the world remain imperishable. His thoughts on substance as activity and the universe as an inter-related unit demonstrate immense fertility in the history of thought. Ultimately, the work serves as a bridge, showing how Kant and his successors were compelled to transcend Leibniz's scholastic method while building upon his profound achievements to justify the objective idealism of modern philosophy.
