We enter the world alone, we leave it alone.

The solitary side of our nature demands leisure for reflection upon subjects on which the dash and whirl of daily business, so long as its clouds rise thick about us, forbid the intellect to fasten itself.

Those who seek for something more than happiness in this world must not complain if happiness is not their portion.

Men are made by nature unequal. It is vain, therefore, to treat them as if they were equal.

To deny the freedom of the will is to make morality impossible.

To tell men that they cannot help themselves is to fling them into recklessness and despair.

The best that we can do for one another is to exchange our thoughts freely; and that, after all, is about all.
