Accordingly, in May 1617, Descartes set out for the Netherlands and took service in the army of Prince Maurice of Orange.

RENE DESCARTES (1596-1650), French philosopher, was born at La Haye, in Touraine, midway between Tours and Poitiers, on the 31st of March 1596, and died at Stockholm on the 1th of February 1650.
