Exposing Fake Logic by Avi Sion is a collection of essays written after publication of his book A Fortiori Logic, in which he critically responds to derivative work by other authors who claim to know better. This is more than just polemics; but allows further clarifications of a fortiori logic and of general logic.

It is very difficult to briefly summarize Avi Sion’s philosophy, because it is so wide-ranging. He has labeled it ‘Logical Philosophy’, because it is firmly grounded in formal logic, inductive as well as deductive. This original philosophy is dedicated to demonstrating the efficacy of human reason by detailing its actual means; and to show that the skepticism which has been increasingly fashionable and destructive since the Enlightenment was (contrary to appearances) quite illogical – the product of ignorant, incompetent and dishonest thinking. This guide contains a list of his 27 published books, showing their chronology and interrelationships. This is followed by a collection of the abstracts of these books, summarizing their main contents. Also found here are links to all websites, where his books can be freely read. Hopefully, this guide will make it easier for readers to find what interests them the most, in view of the sheer volume of it all.

Inductive Logic is a ‘thematic compilation’ by Avi Sion. It collects in one volume many (though not all) of the essays, that he has written on this subject over a period of some 23 years, which all demonstrate the possibility and conditions of validity of human knowledge, the utility and reliability of human cognitive means when properly used, contrary to the skeptical assumptions that are nowadays fashionable. This volume includes essays on the laws of thought, credibility, logical modality, contextuality, adduction, theory formation and selection, induction of actual and modal propositions, factorial induction (factor selection and formula revision), the phenomenological approach, experience, conceptualization, generalization and particularization, causation and its determinations, volition (freewill) and influences thereon, negation, and existential import.

Logic in the Talmud is a ‘thematic compilation’ by Avi Sion. It collects in one volume essays that he has written on this subject in Judaic Logic (1995) and A Fortiori Logic (2013), in which traces of logic in the Talmud (the Mishna and Gemara) are identified and analyzed. While this book does not constitute an exhaustive study of logic in the Talmud, it is a ground-breaking and extensive study.

The Logic of Analogy is a study of the valid logical forms of qualitative and quantitative analogical argument, and the rules pertaining to them. It investigates equally valid conflicting arguments, statistics-based arguments and their utility in science, arguments from precedent used in law-making or law-application, and examines subsumption in analogical terms. Included for purposes of illustration is a large section on Talmudic use of analogical reasoning.

Theology is about God and Creation, or more precisely perhaps about our ideas of them, how they are formed and somewhat justified, although it is stressed that they can be neither proved nor disproved. This book is a thematic compilation drawn from past works by the author over a period of thirteen years. A new essay was added in 2022.

This interdisciplinary Handbook provides an in-depth analysis of the complex security phenomenon of disinformation and offers a toolkit to counter such tactics. Disinformation used to propagate false, inexact or out of context information is today a frequently used tool of political manipulation and information warfare, both online and offline. This Handbook evidences a historical thread of continuing practices and modus operandi in overt state propaganda and covert information operations. Further, it attempts to unveil current methods used by propaganda actors, the inherent vulnerabilities they exploit in the fabric of democratic societies and, last but not least, to highlight current practices in countering disinformation and building resilient audiences. The Handbook is divided into six thematic sections. The first part provides a set of theoretical approaches to hostile influencing, disinformation and covert information operations. The second part looks at disinformation and propaganda in historical perspective offering case study analysis of disinformation, and the third focuses on providing understanding of the contemporary challenges posed by disinformation and hostile influencing. The fourth part examines information and communication practices used for countering disinformation and building resilience. The fifth part analyses specific regional experiences in countering and deterring disinformation, as well as international policy responses from transnational institutions and security practitioners. Finally, the sixth part offers a practical toolkit for practitioners to counter disinformation and hostile influencing. This handbook will be of much interest to students of national security, propaganda studies, media and communications studies, intelligence studies and International Relations in general.
