Aristotle (384 - 322 B.C.) taught logic to Alexander the Great and by virtue of his philosophical works to every philosopher since from Marcus Aurelius to Thomas Aquinas to Mortimer J. Adler. Now Adler instructs the world in the uncommon common sense of Aristotelian logic presenting Aristotle s understandings in a current delightfully lucid way. He brings Aristotle s work to an everyday level. By encouraging readers to think philosophically Adler offers us a unique path to personal insights and understanding of intangibles such as the difference between wants and needs the proper way to pursue happiness and the right plan for a good life.
