Author: René Descartes
René Descartes (La Haye en Touraine, March 31,
1596 – Stockholm, February 11, 1650), was a French philosopher
and mathematician. He wrote his most important work in The
Republic of the Seven United Netherlands (Dutch Republic),
where he lived 20 years. He is commonly considered to be one
of the twenty most important philosophers all times. One of
his achievements in Mathematics was his work on the base for
analytical geometry, the bridge between algebra and geometry.
Book: In 1636 at the insistence
of his friends he published his 'Discours de la methode.'
He was not only the first one to reject the philosophy of
Aristotle, but he also replaced it by an own viable philosophical
system, with which he formed the basis for 17th century rationalism.
Descartes postulated three certainties as a grounding of this
rationality: the certainty of doubt, the certainty of the
existence of God and the certainty of the existence of the
outside world. To underline the existence of God, Descartes
supported two theses (a posteriori and a priori). This science
supports what we are seeing on page one. Under a radiating
sun, in which God's name is written, is a treasure hunter
digging for treasures."
