Imagination.—It is that deceitful part in man, that mistress of error and falsity, the more deceptive, that she is not always so; for she would be an infallible rule of truth, if she were an infallible rule of falsehood. But being most generally false, she gives no sign of her nature, impressing the same character on the true and the false. I do not speak of fools, I speak of the wisest men; and it is among them that the imagination has the great gift of persuasion. Reason protests in vain; it cannot set a true value on things.
