Sextus Empiricus and Greek Scepticism

First published in 1899. According to Wikipedia: "Sextus Empiricus (c. 160-210 AD), was a physician and philosopher, and has been variously reported to have lived in Alexandria, Rome, or Athens. His philosophical work is the most complete surviving account of ancient Greek and Roman skepticism... Sextus Empiricus raised concerns which applied to all types of knowledge. He doubted the validity of induction[2] long before its best known critic David Hume, and raised the regress argument against all forms of reasoning."
