On the argument from design, cf. Aristotle, De Part. Anim. iii. 1, as quoted and translated by Cudworth, III. xxxvii. 3:  “A carpenter would give a better account than so, for he would not think it sufficient to say that the fabric came to be of such a form because the instruments happened to fall so and so, but he will tell you that it is because himself made such strokes, and that he directed the instruments and determined their motion after such a manner, to this end that he might make the whole a fabric fit and useful for such purposes.”  On the strength and weakness of the argument from design, in view of modern speculation, suggestive matter is contained in Dr. Eagar’s Buther’s Analogy and Modern Thought, p. 49 et sq.
