Ghazalian Piety

As related by Ibn Tufayl:

If my words have done no more than to shake you in the faith of your fathers, that would have been reason enough to write them. For he who does not doubt does not look; and he who does not look will not see, but must remain in blindness and confusion.

--From Lenn E. Goodman's translation of Hayy Ibn Yaqzan, 101.
