 For instance, a person would not experience the world as an orderly, rule-governed place unless time, space and causality were determinant functions in the form of perceptual faculties, i. e., there can be no experience in general without space, time or causality as particular determinants thereon.The claim is more formally known as Kant's transcendental deduction and it is the central argument of his major work, the "Critique of Pure Reason".The transcendental deduction argues that time, space and causality are ideal as much as real.
