Note 17 — PHILOSOPHICAL PROBLEMS.
Paul Carus translation
Page 116, Note 17.—Kant called his philosophy transcendental idealism, and his followers insisted upon the importance of transcendentalism. They were opposed by naturalists, who scorned theory and insisted on the facts of experience.
For the meaning of the word “transcendental” see the translator’s Fundamental Problems, p. 30 et passim, and Primer of Philosophy, p. 66. “Transcendent” means what transcends human knowledge, i. e., what is unknowable, but “transcendental” is in Kantian terminology non-sensory or formal knowledge such as pure logic and arithmetic, involving the principles of theory or systematic abstract thought.
