An ancient Indian treatise on statecraft, economic policy and military strategy by Kautilya and Vishnugupta, who are traditionally identified with Chanakya (c. 350-283 BCE). In this treatise, the behaviors and relationships of the people, the King, the State, the Government Superintendents, Courtiers, Enemies, Invaders, and Corporations are analysed and documented. Roger Boesche describes the Arthasastra as "a book of political realism, a book analysing how the political world does work and not very often stating how it ought to work, a book that frequently discloses to a king what calculating and sometimes brutal measures he must carry out to preserve the state and the common good."

Answer this question, if possible (if impossible, reply "unanswerable"): When was Chanakya alive?
350-283 BCE
