There is some stuff in the video that is not quite right. Diogenes was not necessarily the first cynic. And he also did not live constantly in a barrel, or virtually on the street. During a ship voyage, he fell into slavery and was then bought in Corinth by the philosopher Xeniades, who entrusted him with the education of his sons. Diogenes came from the upper class. His father was responsible for the coinage of Athens, quasi head of the The Federal Reserve of Athens. There he probably cheated on a grand scale and had to flee Athens.
But still the video offers some interesting aspects, especially for beginners who have never heard of the philosophical movement of the Cynics and at least, it is entertaining.
