ABSTRACT
This introduction presents an overview of the key concepts discussed in the preceding chapter of this book. The book emphasizes the active speech-contextual roles of assertions or judgements in statements as well as those of assent or dissent as truth-value ascribing acts. It explains Avicenna's view concerning the logical model that is constructed, in symbolic fabric, on the basis of those contextual sentences which qualify for being called "true" or "false". The book considers in more detail the constitutive parts of a statement, clarifying the theoretical distinction between what one might consider objects or substances in the world and what the categories one uses to describe or to work with these. It formulates a foundational question that arises from the author's treatment of Avicenna's logic, and the author makes an analogy between this question and a parallel one which arises from certain views which Avicenna has in the field of Physics.
