The article discusses Kant's ideas on transcendental philosophy and ontology. It argues that Kant's views on these subjects are not as different as commonly thought. Kant's Critique of Pure Reason focuses on two branches of transcendental cognition: transcendental philosophy proper and transcendental critique. The chapter shows that both Wolffian ontology and transcendental philosophy aim to explain the cognitive elements needed for understanding objects. Kant's unique contribution lies in his second-order investigation into metaphysics through transcendental critique. He criticizes how others have understood terms like 'ontology' and 'transcendental philosophy'.
