This book is a treatise on dialectical argument, a practice perhaps as old as human language, systemized for the first time by Aristotle. This seminal text offers many important insights into his conception of logic, his development of the notion of the predicables, and his ideas on the method of philosophical inquiry itself. Aristotle's works have influenced science, religion, and philosophy for nearly two thousand years. He could be thought of as the father of logical thought. Aristotle wrote: "There is nothing in the intellect that was not first in the senses." He wrote that everything that is learned in life is learned through sensory perception. Aristotle was the first to establish the founding principle of logic. The great writer Dante called Aristotle "The Master of those who know."
