Note 287 — INTRODUCTION (continued 2)

The propositions of pure natural science are not separately treated in § 4 of the Prolegomena, though the subsequent argument implies that this has been done. Vaihinger’s inference (i. p. 310) that a paragraph, present in Kant’s manuscript, has been dropped out in the process of printing the fourth section (the section which contains the paragraphs transposed from the end of § 2) seems unavoidable. The missing paragraph was very probably that which is here given in B 17.
