From the outset, pragmatists wanted to reform philosophy and bring it more in line with the scientific method as they understood it. They argued that idealist and realist philosophy had a tendency to present human knowledge as something beyond what science could grasp. They held that these philosophies then resorted either to a phenomenology inspired by Kant or to correspondence theories of knowledge and truth. Pragmatists criticized the former for its a priorism, and the latter because it takes correspondence as an unanalyzable fact. Pragmatism instead tries to explain the relation between knower and known.
