C. Read: Logic: Deductive and Inductive, London: Simkin, Marshall (1920), v. – Digitalisat („The work may be considered, on the whole, as attached to the school of Mill; to whose System of Logic, and to Bain's Logic, it is deeply indebted. Amongst the works of living writers, the Empirical Logic of Dr. Venn and the Formal Logic of Dr. Keynes have given me most assistance.“)
