Wit and valour are qualities that are more easily ascertained than virtue, or the love of wisdom. — Edward Gibbon

Benevolence is the foundation of Justice, since we are forbidden to injure those we are bound to assist. A prophet may reveal the secrets of Heaven and futurity, but in his moral precepts he can only repeat the lessons of our own hearts.

To an active mind, indolence is more painful than labor ...

In the spirit of enthusiasm or vanity, the prophet [Muhammad] rests the truth of his mission on the merit of his book; audaciously challenges both men and angels to imitate the beauties of a single page; and presumes to assert that God alone could dictate this incomparable performance. This argument is most powerfully addressed to a devout Arabian, whose mind is attuned to faith and rapture; whose ear is delighted by the music of sounds; and whose ignorance is incapable of comparing the productions of human genius... If the composition of the Koran exceed the faculties of a man to what superior intelligence should we ascribe the Iliad of Homer, or the Philippics of Demosthenes?
