(Rene Descartes) + (Triangle) = (Andre Gide)

________________________________________________________________________________________________

I think, therefore I am.

        

I think
 that the angles of a triangle
  are equal to two right angles,
therefore I am.

Rene Descartes
(1596-1650)



Andre Gide→
(1869-1951)








I think a Cartesian inquiry
about the triangle can be found  here.

But I know that the Gide quote in the middle of this page   

is from "Book 2" of  Later Fruits of the Earth.
