Abstract or Table of Contents
A word of explanation is in order regarding the title of the set of computer-based tutorials, ANALYTICS, for which this text is a companion. The computer tutorials are designed primarily to exercise you in the use of basic tools and techniques of logical analysis. The science of formal logic and the systematic study of what makes reasoning good or bad were invented by Aristotle over twenty centuries ago. Modern logic has made considerable progress on Aristotle's monumental beginnings. But the nature of logical analysis as we pursue it today still owes a great deal to Aristotle's original inspiration and definition. Any history of philosophy or logic will attest to this.
