Note 2283 — II. His Criticism of and Part in Medieval Learning (continued 2)

In articles published in 1915 (“Adelard of Bath and the Continuity of Universal Nature” in Nature, XCIV, 616-17; “Roger Bacon and Gunpowder,” in Science, XLII, 799-800) I disputed Professor Duhem’s crediting Bacon with originating the theory of universal nature and Colonel Hime’s ascribing to him the invention of gunpowder. In the present work these articles will be found embodied in the chapter on Adelard of Bath and in Appendix II to this chapter.
