The Art of Logic by Avi Sion is a collection of recent essays on various topics in logic theory and in applied logic. The same faculty and art of logic is called for in formulating theoretical logic and in applying its findings to diverse fields. The essays here collected deal with some very important issues in logic, philosophy, and spirituality, which he had not previously treated in as much detail if at all.

Essay on the Principles of Logic: A Defense of Logical Monism, 2023

Table of Contents for my translation of Michael Wolff's Essay on the Principles of Logic: A Defense of Logical Monism. Michael Wolff's book is an attempt to show that a non-truth-functional syllogistic logic is the only formal and general logic - in that it introduces no specific conceptual content into its formulas and principles. Further, he shows that post-Fregean logics can be reproduced within syllogistic, so long as postulates are added which are not universally valid. Yet because "classical" logics depend on postulates that are not valid in every case, they cannot earn the title of formal and general logic with the same right as the syllogistic. The book includes a full comparison of syllogistic with class-logical and function-theoretic logical languages, as well as a reconstruction of Aristotle's syllogistic within Wolff's new syllogistic language.
