If you would be a real seeker...

If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.

--Rene Descartes

Dubito ergo cogito; cogito ergo sum.
(I doubt, therefore I think; I think therefore I am.)

--Rene Descartes

Where there is hatred, let me...

Where there is hatred, let me sow love. Where there is injury, pardon. Where there is doubt, faith.

--Saint Francis of Assisi
