Aristotle taught logic to Alexander the Great and, through his philosophical work, to every philosopher after him and to this day. In this classic book, American philosopher Mortimer J. Adler teaches us the essence of the uncommon sense of Aristotelian logic, presenting Aristotle’s cosmology and philosophy in a modern, engaging, and clear manner.

Bringing Aristotelian work into daily life and encouraging readers to think philosophically, this book opens a unique path for cultivating thought and critical ability, self-awareness, and self-actualization.

“This is a self-help book in the best sense of the word […] The Aristotelian wisdom that Adler imparts is unparalleled. And it shows us, above all and once again, that philosophy, real philosophy, can indeed be invaluable in our lives.” Chicago Tribune Book World
