 The importance of this for the argument from design is clear. The gap between human artifacts and the whole universe is “vast” (D, 2.8/144, 12.6/216–7, 12.33/227). Any resemblance or similarity of this kind is so remote and slight that all reasoning on this basis is “both uncertain and useless” (EU, 11.23 /142). When we use analogies that are this weak and imperfect then only doubt and uncertainty can result (D, 2.17/147,5.1/165; T, 1.3.12.25/142).
