1796 – 1879
Immanuel Hermann Fichte (1796–1879) was a German philosopher and the son of Johann Gottlieb Fichte, who developed his own system of speculative theism within the tradition of post-Kantian idealism. He argued that a coherent metaphysics requires positing a personal God as the ground of finite minds, synthesizing idealist epistemology with theistic commitments. His work bridges German Idealism and 19th-century Christian philosophy, and he also produced the authoritative edition of his father's collected writings.
