The article discusses different interpretations of Kant's transcendental philosophy and identifies two key shifts: methodological and metaphysical. The methodological shift focuses on how we understand and justify our knowledge of objects, leading to a new way of thinking in philosophy. The metaphysical shift involves separating objects into the actual thing itself and how it appears to us, shaping the essence of transcendental idealism. Overall, these shifts define the essence of Kant's transcendental philosophy and its impact on modern philosophy.
