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.
