We promise according to our hopes and perform according to our fears.

Hope and fear are inseparable. There is no hope without fear, nor any fear without hope.

Neither love nor fire can subsist without perpetual motion; both cease to live so soon as they cease to hope, or to fear.

Nothing is impossible; there are ways that lead to everything, and if we had sufficient will we should always have sufficient means. It is often merely for an excuse that we say things are impossible.

No man is clever enough to know all the evil he does.

We get so much in the habit of wearing disguises before others that we finally appear disguised before ourselves.
