Exposing Fake Logic

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.

A collection of “lively, plain-language debunkings of seven cases of quack or fraudulent science and . . . antiscientific bias in general” (Booklist). Is hydro-fracking safe? Is climate change real? Did the moon landing actually happen? How about evolution: fact or fiction? Author-illustrator Darryl Cunningham looks at these and other hot-button science topics and presents a fact-based, visual assessment of current thinking and research on eight different issues everybody’s arguing about. His lively storytelling approach incorporates comics, photographs, and diagrams to create substantive but easily accessible reportage. Cunningham’s distinctive illustrative style shows how information is manipulated by all sides; his easy-to-follow narratives allow readers to draw their own fact-based conclusions. A graphic milestone of investigative journalism! “Cartoonist Darryl Cunningham . . . is a welcome voice, shedding some much needed light on the darker areas of science and culture. . . . Cunningham does a remarkable job with difficult material and for high school students, just opening their eyes to the world around them, this is a terrific primer.” —ComicMix
