"Learning Critical Thinking From Logical Principles" is written as a general education textbook for a course in logic at either the high school or college level. General concepts are first presented, then followed by exploration questions in which students are asked to think about and apply each concept to specific situations. Acquiring accurate information is the foundation for arriving at correct logical conclusions. Students are taught to use graphs to see patterns in observations and to draw inductive and deductive conclusions. Examples are drawn from everyday situations in life as well as from other fields such as science, mathematics, politics, psychology, philosophy, and religion.
