He (Mohammed) seduced the people by promises of carnal pleasure to which the concupiscence of the flesh urges us. His teaching also contained precepts that were in conformity with his promises, and he gave free rein to carnal pleasure. In all this, as is not unexpected; he was obeyed by carnal men. As for proofs of the truth of his doctrine, he brought forward only such as could be grasped by the natural ability of anyone with a very modest wisdom. Indeed, the truths that he taught he mingled with many fables and with doctrines of the greatest falsity.

A man's heart is right when he wills what God wills.

How can we live in harmony? First we need to know we are all madly in love with the same God.

He that obstinately denieth the truth before men upon earth, wilfully refuseth his soul's health in heaven.

Arrive at knowledge over small streamlets, and do not plunge immediately into the ocean, since progress must go from the easier to the more difficult.

It is requisite for the relaxation of the mind that we make use, from time to time, of playful deeds and jokes.

Love follows knowledge.
