An accessible introduction to inductive logic, this work comprises a series of lectures which John Venn delivered at Cambridge. Many are a commentary on John Stuart Mill’s A System of Logic: Ratiocinative and Inductive, both critiquing and expanding on Mill’s arguments. Venn’s use of real-world examples makes this work especially helpful for those interested in applying inductive logic in debates.

In this volume, John Venn provides a thorough analysis of Romans 6 through 8. He gives special focus to the subject of personal holiness, which he identifies as the central theme of these chapters, which are “more systematic in the treatment of it, than any other portion of Scripture.”
