  There were two possible ways of working out the Neo-Kantianism of F.A. Lange. Either the Kantian standpoint could be developed, on the basis of a closer and more accurate study of Kant’s teaching, and this is what Cohen has done, or one could bring Lange’s Neo-Kantianism into relation with empiricism and positivism. This has been done in my philosophy of “As if,” which also leads to a more thorough study of Kant’s “As if” theory. (PAO xxii)
