In attempting to apply the principles of his doc trine of science to the theory of morals and the law of nature, Fichte exhibited many original and para doxical opinions, along with some very just and in genious philosophical observations. In his later writings he considerably modified his original theory of the doctrine of science, and produced a system of philosophical and religious mysticism, which appears to have given birth to the transcendental idealism of Schelling; an author who seems to have carried the extravagance of speculative reasoning to its utmost limits.
