IX. 140 They talk in high-flown language, not always conveying very precise ideas, of a supposed system of inductive logic, which is to supersede the syllogistic, and really to accomplish still more than the other even attempts. Ibid. 150 An inductive logic would be highly useful as a supplement to the syllogistic logic, not to supersede it. 1830Herschel Stud. Nat.
