That an author's work is the mirror of his mind is a position that has led to very false conclusions. If Satan himself were to write a book it would be in praise of virtue, because the good would purchase it for use, and the bad for ostentation.

If it be true that men of strong imaginations are usually dogmatists--and I am inclined to think it is so--it ought to follow that men of weak imaginations are the reverse; in which case we should have some compensation for stupidity.
