There are two equally dangerous extremes-to shut reason out, and to let nothing else in.

That queen, of error, whom we call fancy and opinion, is the more deceitful because she does not always deceive. She would be the infallible rule of truth if she were the infallible rule of falsehood; but being only most frequently in error, she gives no evidence of her real quality, for she marks with the same character both that which is true and that which is false.

How vain painting is-we admire the realistic depiction of objects which in their original state we don't admire at all.

Generally we are occupied either with the miseries which now we feel, or with those which threaten; and even when we see ourselves sufficiently secure from the approach of either, still fretfulness, though unwarranted by either present or expected affliction, fails not to spring up from the deep recesses of the heart, where its roots naturally grow, and to fill the soul with its poison.
