What is the Copernican turn in Kantian philosophy?

In his philosophy, Immanuel Kant proposed a radical inversion of traditional epistemology that he compared to the Copernican Revolution in astronomy. Instead of assuming that the human mind must conform to external objects to gain knowledge, Kant argued that objects of experience must conform to our innate spatial and temporal forms of intuition and categories of understanding. This shift established transcendental idealism, asserting that we can only have knowledge of appearances rather than things in themselves.

What we know

• Kant drew a parallel to the Copernican Revolution by proposing that objects of experience conform to human spatial and temporal forms of intuition and categories of understanding. [1]
• The traditional method prior to Kant's proposal attempted to show how the human mind might conform to its objects. [1]
• Through his transcendental idealism, Kant argued that space and time are mere forms of intuition structuring all experience, limiting our knowledge to appearances rather than things in themselves. [1]
• German idealism developed out of the work of Immanuel Kant in the 1780s and 1790s as a manifestation of the modern demand for rationality and freedom. [4]
