We can only choose between two kinds of life, the active and the contemplative. - Étienne Gilson

All realism derives from the analysis of knowledge; all idealism derives from the analysis of a thought.

If there is a single initial error at the root of all the difficulties philosophy is involved in, it can only be the one Descartes committed when he decreed, a priori, that the method of one of the sciences of reality was valid for the whole of reality.

If there is something more in a living being than a pure mechanism, Descartes is bound in advance to miss it.
