Kant argues that space and time are not empirical concepts nor features of things-in-themselves. Rather, they are the —the subjective, a priori conditions under which anything can appear to us.

Kant’s genius was to reconceive the subject-object relation. Instead of assuming that the mind must conform to objects, Kant proposed that . Just as Copernicus hypothesized the earth’s motion to explain celestial observations, Kant hypothesized that the mind actively structures experience. Thus, we can have a priori (experience-independent) knowledge not of things as they are in themselves ( noumena ), but of things as they appear to us ( phenomena ). Kant argues that space and time are not
"Act only according to that maxim whereby you can at the same time will that it should become a universal law."
The central question of the Critique of Pure Reason is: If Kant can answer this, he grounds mathematics and natural science as genuine knowledge while simultaneously showing why traditional metaphysics (God, freedom, immortality) cannot attain such status.

In his masterpiece, The Critique of Pure Reason (1781), Kant argued that both were half-right. He proposed that while our knowledge begins with experience, the mind isn't a "blank slate." Instead, the human mind has built-in structures—like software—that organize raw sensory data.
Before Kant, philosophers argued over whether knowledge came from experience ( Empiricism ) or pure reason ( Rationalism effecting a “Copernican Revolution” in epistemology.
Kant’s moral philosophy is "deontological," meaning it focuses on duty and rules

central insight was this: Objects must conform to our mind.
Immanuel Kant’s Critique of Pure Reason (1781/1787) represents a watershed moment in Western philosophy, effecting a “Copernican Revolution” in epistemology. This article provides a systematic exposition of Kant’s theoretical philosophy. It begins with the motivation for the critical project—the need to reconcile empiricism and rationalism while securing the foundation for Newtonian physics. It then examines Kant’s transcendental method, the distinction between a priori and a posteriori knowledge, and the nature of synthetic a priori judgments. The core of the analysis focuses on the Transcendental Aesthetic (space and time as pure intuitions) and the Transcendental Analytic (the categories of the understanding and the Transcendental Deduction). Finally, the article addresses the crucial distinction between phenomena and noumena, concluding with the doctrine of transcendental idealism and its implications for metaphysics.
