Philosophy of Art Kant—4
Although we rely on experience, on ‘receptivity’ or what Kant calls ‘intuition’ for the particular
contents of our knowledge, the structure or form of that experience is provided by the human
mind, or what Kant calls the ‘understanding’ (Verstand). Without the mind to provide the
structure or form to what is given through the senses we would have no experience of the
external world at all.
This is what Kant described as the “Copernican Revolution” in philosophy
prior to Copernicus they couldn’t satisfactorily explain the movement of the heavens based on
the supposition that the heavens revolved around the spectator
(the sun revolving around the earth)
Copernicus achieved a breakthrough by supposing that it was the spectator that revolved
(the earth revolving around the sun)
similarly Kant thought he had achieved a breakthrough in metaphysics
prior to Kant the mind was conceived as a passive mirror of nature
and crucial notions like space and time and causality were thought to reside outside the mind and
only passively mirrored in the mind
the foundation for making objective, universally valid empirical judgments (judgments about the
external world) was thought by rationalists to lie in a priori innate ideas that mirrored an
objective reality
or by empiricists in ideas given in sensation (a posteriori) whose source lay outside the mind
both rationalists and empiricists assumed the mind to be a passive mirror of nature
for Kant the empiricists were right that the content of our knowledge comes from experience
but the mind supplies the form to that content and thus the rationalists were right about there
being some non-analytic a priori knowledge
thus the Copernican Revolution is that Kant finds the source of the objective, universally valid
empirical judgments to lie within the mind
The mind is no longer a passive mirror, but actively structures or imposes form upon our
experience.
How, one might ask, if the source is within the mind, can the judgments be objective and
universally valid?
For Kant, the universality lies in the structure of the human mind
all of us have a mind that is hardwired to experience the world through the categories of space
and time and causality
The aim of the Critique of Pure Reason is to demonstrate that we can have a priori knowledge of
the structure or form of experience.
He calls this knowledge “transcendental”
it concerns the nature of our experience but “transcends” the way empiricists supposed it was
derived
the project Kant undertakes is to lay out the structure of the human mind
he seeks transcendental knowledge of the basic form or structure of experience
