The journal "History and Philosophy of Logic" includes articles, notes, and book reviews related to the history and philosophy of logic. Here, 'logic' is broadly understood as any body of knowledge that was considered logical at the time. 'History' encompasses both ancient content and research from this century; however, the editors do not accept articles on recent work on a specific topic, including review articles. 'Philosophy' refers to broad and general issues: professional articles currently classified as 'philosophical logic' will not be published. The editors will consider articles that explore the relationship between logic and other branches of knowledge, but the components of logic must be substantive. Topics without temporal constraints will be interpreted in historical and philosophical contexts. Each topic includes its own meta-logic where appropriate.
