In what way was Kant's revolution in epistemology similar to Copernicus' revolution in astronomy?

The scientific world view of the universe was radically upended when Copernicus demonstrated that the sun was the center of the solar system, challenging the preexisting theory that man and the earth were the center of the universe.

In his Critique of Pure Reason, Kant upended the Enlightenment's view that human reason, rationalism, and empirical observation were the only ways to acquire knowledge and that knowledge could only come from humankind.

Kant demonstrated the errors in the Cartiesian dualism of human reason and empirical evidence, demonstrating that human reason could not be the ultimate source of truth because Enlightenment philosophy had eliminated all references to the supernatural (or God), leaving no room for an ultimate source of truth.

The human mind uses noumena, a priori knowledge, and human reason to create phenomena. Phenomenon is the reality created inside the human mind. Kant relies on a priori truths that seem reasonable to the human mind. Empirical observations can create noumena in the human mind. These noumena may or may not relate to objective reality. Kant holds that objective reality is unknowable.

The internal beauty of an idea is more significant in Kant's post-enlightenment philosophy than any empirical observations, which are unreliable due to their subjectivity and influence from the human mind.

The great popularity of theories such as Marx's and Darwin's owes much to Kant's theories; the intrinsic value of these theories outweighs any empirical proof of their validity.

Kant's revolution in epistemology was similar to Copernicus' revolution in astronomy in that both challenged prevailing views by proposing radically different frameworks for understanding the world. Kant shifted the focus of epistemology from the external world to the mind, much like Copernicus shifted the focus of astronomy from Earth to the Sun.
