 We can see Cohen’s view of philosophical method in its nascent form emerge from his interpretation of Kant’s Analytic of Principles and the Prolegomena to Any Future Metaphysics. However, Cohen would articulate the method clearly only much later, in his mature writing. Only later would Cohen (and his students) call it the “transcendental method.” (See Luft 2015, Ch. 1.5 for a thorough discussion of the transcendental method.)
