For the record, Kneale: English logician, born in Liverpool, Fellow of Exeter College, Oxford and Professor of Moral Philosophy at University of Oxford. Kneale is best known for the scholarly knowledge and clear exposition of the history of logic that he produced with his wife. Although Aristotle and Frege are the most important figures in this history, the work drew attention to other important developments in Greek, medieval, and modern logic. Kneale's examination of probability and induction develops his own theories, especially that laws of nature are modal propositions about natural necessities. His main work is possibly (probably?) Probability and Induction (1949). Grice discusses Kneale (whom he met at Corpus Christi) in "Prejudices and predilections, which become the life and opinions of Paul Grice", by Paul Grice. Grice was fascinated by the complexities of inductive reasoning that Kneale was able to formulate -- "quite clearly, even if sometimes motivating us to double check what his 'secondary' induction amounted to!". Cheers, Speranza Refs: Grice, "Aspects of reason" -- John Locke lectures -- on reasoning and inductive reasoning.
