Logic is defined as the science and art of sound reasoning. Considering that all human achievement must begin with thought, we must conclude that all of our problems, moral educational, religious, and even political, social and economic, must originate in bad thinking. Also, recognizing that the ability to reason is the very essence of and definition of human nature, we see why logic, in the ages of Faith, had the place of honor among the liberal arts. This course begins with definitions. We learn how to define and how to differentiate; which are two essential functions of human reason. This is the first Philosophy course to take. (21 Tapes)
