Be not the slave of your own past.

The solar system has no anxiety about its reputation.

Men cease to interest us when we find their limitations

The kingdom of man over nature, which cometh not with observation,--a dominion such as now is beyond his dream of God,--he shall enter without more wonder than the blind man feels who is gradually restored to perfect sight.

Every word which is used to express a moral or intellectual fact, if traced to its root, is found to be borrowed from some material appearance.

All our progress is an unfolding, like the vegetable bud. You have first an instinct, then an opinion, then a knowledge, as the plant has root, bud, and fruit. Trust the instinct to the end, though you can render no reason. It is vain to hurry it. By trusting it to the end it shall ripen into truth, and you shall know why you believe.

We forget ourselves and our destinies in health, and the chief use of temporary sickness is to remind us of these concerns.
