Avi Sion

Judaic logic: A Formal Analysis of Biblical, Talmudic and Rabbinic Logic is an original inquiry into the forms of thought determining Jewish law and belief, from the impartial perspective of a logician. Judaic Logic attempts to honestly estimate the extent to which the logic employed within Judaism fits into the general norms, and whether it has any contributions to make to them.

Paradoxes and their Resolutions is Avi Sion’s latest ‘thematic compilation’. It collects in one volume the essays that he has written in the past (over a period of some 27 years) on this subject. It comprises expositions and resolutions of many (though not all) ancient and modern paradoxes, including: the Protagoras-Euathlus paradox (Athens, 5th Cent. BCE), the Liar paradox and the Sorites paradox (both attributed to Eubulides of Miletus, 4th Cent. BCE), Russell’s paradox (UK, 1901) and its derivatives the Barber paradox and the Master Catalogue paradox (also by Russell), Grelling’s paradox (Germany, 1908), Hempel's paradox of confirmation (USA, 1940s), and Goodman’s paradox of prediction (USA, 1955). This volume also presents and comments on some of the antinomic discourse found in some Buddhist texts (namely, in Nagarjuna, India, 2nd Cent. CE; and in the Diamond Sutra, date unknown, but probably in an early century CE).

"Marcus Aurelius Antoninus was the sixteenth emperor of Rome -- and by far the most powerful and wealthy man in the world. Yet he was also an intensely private person, with a rich interior life and deep reservoirs of personal insight. He collected his thoughts in notebooks, gems which have come to be called his Meditations. Never intended for publication, the work survived his death and has proved an inexhaustible source of wisdom and one of the most important Stoic texts of all time. In often passionate language, the entries range from essays to one-line aphorisms, and from profundity to bitterness. Marcus wrote to console himself in the face of the shortness of life, the shoddiness of the world, and the challenges of being human. He asks the very same questions that every thinking person must ask themselves today: Does the universe have a moral purpose, and what is my role in it? What exactly is it to be a good person, and how do I get there? Life is short: what does that mean for me? How can I get to know myself better? Anyone who is puzzled by such questions or searching for answers will profit from this timeless book, which is both an important historical document and a personal spiritual diary. This annotated edition will be the definitive translation of this classic and much-beloved text, with copious notes that will illuminate one of the greatest works of popular philosophy for new readers and enrich the understanding of even the most hardcore Stoic"--

A FORTIORI LOGIC: INNOVATIONS, HISTORY AND ASSESSMENTS, by Avi Sion, is a wide-ranging and in-depth study of a fortiori reasoning, comprising a great many new theoretical insights into such argument, a history of its use and discussion from antiquity to the present day, and critical analyses of the main attempts at its elucidation. Its purpose is nothing less than to lay the foundations for a new branch of logic, and greatly develop it; and thus to once and for all dispel the many fallacious ideas circulating regarding the nature of a fortiori reasoning.

Phenomenology as a tradition owes its name to Edmund Husserl, in his Logical Investigations (1900-1). It began as a bold new way of doing philosophy, an attempt to bring it back from abstract metaphysical speculation and empty logical calculation in order to come into contact with concrete living experience. As formulated by Husserl, Phenomenology is the investigation of the structures of consciousness that enable consciousness to refer to objects outside itself. It soon broadened into a world-wide and now century-old tradition. Phenomenological versions of theology, sociology, psychology, psychiatry and literary criticism, have all been engendered, so that phenomenology remains one of the most important traditions of contemporary philosophy. Phenomenology is currently extending into new areas such as gender, ethnicity, multiculturalism, and ecology. An effort has been made in these four volumes to include representatives of all the major tendencies within phenomenology and to provide documentation of the critical discussion of its central topics.

Logical Criticism of Buddhist Doctrines is a ‘thematic compilation’ by Avi Sion. It collects in one volume the essays that he has written on this subject over a period of some 15 years after the publication of his first book on Buddhism, Buddhist Illogic. It comprises expositions and empirical and logical critiques of many (though not all) Buddhist doctrines, such as impermanence, interdependence, emptiness, the denial of self or soul. It includes his most recent essay, regarding the five skandhas doctrine.

Future Logic is an original and wide-ranging treatise of formal logic. It deals with deduction and induction, of categorical and conditional propositions, involving the natural, temporal, extensional, and logical modalities. This is the first work ever to strictly formalize the inductive processes of generalization and particularization, through the novel methods of factorial analysis, factor selection and formula revision. This is the first work ever to develop a formal logic of the natural, temporal and extensional types of conditioning (as distinct from logical conditioning), including their production from modal categorical premises.

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. This collection includes essays on: a fortiori argument (in general and in Judaism); Luis Duarte D’Almeida; Mahmoud Zeraatpishe; Michael Avraham (et al.); an anonymous reviewer of BDD (a Bar Ilan University journal); and self-publishing. None of these essays were previously published in print, although most of them were posted online.

Volition and Allied Causal Concepts is a work of aetiology and metapsychology. Aetiology is the branch of philosophy and logic devoted to the study of causality (the cause-effect relation) in all its forms; and metapsychology is the study of the basic concepts common to all psychological discourse, most of which are causal. This is a work of ambitious scope, intent on finally resolving philosophical and logical issues that have always impeded progress in psychology.

A Short Critique of Kant’s Unreason is a brief critical analysis of some of the salient epistemological and ontological ideas and theses in Immanuel Kant’s famous Critique of Pure Reason. It shows that Kant was in no position to criticize reason, because he neither sufficiently understood its workings nor had the logical tools needed for the task.

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.

No to Sodom is an essay against homosexuality, using biological, psychological, spiritual, ethical and political arguments.

The Laws of Thought is an exploration of the deductive and inductive foundations of rational thought. The author here clarifies and defends Aristotle’s Three Laws of Thought – and introduces a Fourth Law of Thought implicit in and crucial to them, viz. the Principle of Induction. This book is a thematic compilation drawn from past works by the author over a period of eighteen years.

The feminist movement has challenged many of the unstated assumptions on which ethics as a branch of philosophy has always rested - assumptions about human nature, moral agency, citizenship and kinship. The twenty-six readings in this book express the discontent of a succession of fiercely articulate women writers, from Mary Wollstonecraft to the present day, with the masculine bias of 'morality'. The editors have contributed an overall introduction, which discusses ethics, feminism and feminist themes in ethics, and have provided introductions to each of the readings, designed to situate in their historical and intellectual context. They have also compiled two lists for further reading: `Ethics: a Feminist Bibliography' and 'The Male Tradition'. Ethics: A Feminist Reader is an essential resource for students and teachers of philosophy, political theory and women's studies. For anyone with a stake in progressive sexual politics it is an inspirational guide. The volume contains essays by: Mary Wollstonecraft, Cicely Hamilton, Margaret Sanger, Betty Friedan, Christine Delphy, Andrea Dworkin, Rosalind Coward, Nickie Roberts, Emma Goldman, Virginia Woolf, Simone de Beauvoir, Audre Lorde June Jordan, Jacqueline Rose, Judith Williamson, Seyla Benhabib, Alexandra Kollontai, Adrienne Rich, Kate Soper, Catherine A. MacKinnon, Elizabeth Wilson, Susan F. Parrsons, Rosalind Pollack Petchesky, Sara Ruddick and Sheila Jeffreys.

Logical Philosophy brings together five works by Avi Sion published in 2002-06, namely: Phenomenology (2003), Volition and Allied Causal Concepts (2004), Meditations (2006), Ruminations (2005), and Buddhist Illogic (2002). These works together define what may be termed ‘Logical Philosophy’, i.e. philosophical discourse distinguished by its steadfast reliance on inductive and deductive logic to resolve epistemological and ontological issues. This collection does not include work done on The Logic of Causation in the same period (published in 2003, 2005). (First published 2013.)

Logical and Spiritual Reflections is a collection of six shorter philosophical works, including: Hume’s Problems with Induction; A Short Critique of Kant’s Unreason; In Defense of Aristotle’s Laws of Thought; More Meditations; Zen Judaism; No to Sodom.

In Defense of Aristotle’s Laws of Thought addresses, from a phenomenological standpoint, numerous modern and Buddhist objections and misconceptions regarding the basic principles of Aristotelian logic.

Zen Judaism is a frank reflection on the tensions between reason and faith in today’s context of knowledge, and on the need to inject Zen-like meditation into Judaism. This work also treats some issues in ethics and theodicy.
