Contrary to thinkers, including Newton, who maintained that space and time were real things or substances, Leibniz had arrived at a radically different understanding of the universe and the things found in it. Before Kant, some thinkers, such as Leibniz, had come to the conclusion that space and time were not things, but only the relations among things. Kant presents an account of how we intuit ( German: anschauen) objects and accounts of space and of time. Transcendental idealism was also adopted as a label by the subsequent German philosophers Johann Gottlieb Fichte and Friedrich Wilhelm Joseph von Schelling, Arthur Schopenhauer, and in the early 20th century by Edmund Husserl in the novel form of transcendental-phenomenological idealism. Transcendental idealism is associated with formalistic idealism on the basis of passages from Kant's Prolegomena to any Future Metaphysics, although recent research has tended to dispute this identification. Kant first describes it in his Critique of Pure Reason, and distinguished his view from contemporary views of realism and idealism, but philosophers do not agree on how sharply Kant differs from each of these positions. Background Īlthough it influenced the course of subsequent German philosophy dramatically, exactly how to interpret this concept was a subject of some debate among 20th century philosophers. things as they are independently of how we experience them through our cognitive faculties. Thus Kant's doctrine restricts the scope of our cognition to appearances given to our sensibility and denies that we can possess cognition of things as they are in themselves, i.e. Kant argues that the conscious subject cognizes the objects of experience not as they are in themselves, but only the way they appear to us under the conditions of our sensibility. Kant describes time and space as "empirically real" but transcendentally ideal.

Space and time do not have an existence "outside" of us, but are the "subjective" forms of our sensibility and hence the necessary a priori conditions under which the objects we encounter in our experience can appear to us at all. In the "Transcendental Aesthetic" section of the Critique of Pure Reason, Kant outlines how space and time are pure forms of human intuition contributed by our own faculty of sensibility. By transcendental (a term that deserves special clarification ) Kant means that his philosophical approach to knowledge transcends mere consideration of sensory evidence and requires an understanding of the mind's innate modes of processing that sensory evidence. Kant's epistemological program is found throughout his Critique of Pure Reason (1781). Transcendental idealism is a philosophical system founded by German philosopher Immanuel Kant in the 18th century.
