This series of books presents the fundamentals of logic in a style accessible to both students and scholars. The text of each essay presents a story, the main line of development of the ideas, while the notes and appendices place the research within a larger scholarly context. The basic theme here is the analysis of formal logic in terms of what metaphysical assumptions we need when we develop the formal systems we use. The essays together give a perspective of formal logic as part of the art of reasoning well. The essays are - Possibilities and Valid Inferences, - A General Framework for Semantics for Propositional Logics, - Why Are There So Many Logics? - Truth and Reasoning, - On Translations, - Reflections on Temporal and Modal Logic, - The Timelessness of Classical Predicate Logic, - Events in the Metaphysics of Predicate Logic, - Categoricity with Minimal Metaphysics, - Reflections on G del's Theorems, - On the Error in Frege's Proof that Names Denote, and - Postscript: Logic as the Art of Reasoning Well. | Reasoning and Formal Logic by Richard L Epstein, Paperback | Indigo Chapters
