Bound for the young reader - fond of the ancient Greek philosophy, this booklet presents one of the commendable founders of stoicism, and the world's most cited, painted and sculptured philosopher of all time, Diogenes the Cynic. Employing vigorous tools, like chreia (humor, anecdotes) and his own lifestyle on public display, Diogenes of Sinope revolutionized the asceting teaching to the extent, that was even noticed and celebrated by Alexander the Great. The awe was mutual: Diogenes admired Alexander so deeply, that he was comparing the military genius with Sun. Both died the same day in 323 BC, Alexander - age 33, and Diogenes- age 89; some say Diogenes died by suicide (after learning about Alexander's death) - by holding his breath for several minutes. The cover of this book presents Raphael's famous fresco, 'The School of Athens, ' where the lonely reclining figure in the foreground is Diogenes.
