Aristotle for Everybody
[read by Frederick Davidson, 5h31m @ 64kbps]

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.
