“ To casuistry belongs the decision of all difficulties arising about what a man may lawfully do or not do; what is sin or not sin; what things a man is obliged to do in order to discharge his duty, and what he may let alone without breach of it. The most celebrated writers on this subject, of the Church of England, are Bishop Jeremy Taylor, in his “Ductor Dubitantium;” and Bishop Sanderson, in his “Cases of Conscience.” There was a professor of casuistry in the university of Cambridge, but the title of the professorship has lately been altered to Moral Philosophy.CASULA. (See Chasible.) ”
