All our life passes in this way: we seek rest by struggling against certain obstacles, and once they are overcome, rest proves intolerable because of the boredom it produces.

We never do evil so effectually as when we are led to do it by a false principle of conscience.

We desire truth, and find within ourselves only uncertainty. We seek happiness, and find only misery and death. We cannot but desire truth and happiness, and are incapable of certainty or happiness.

Don't try to add more years to your life. Better add more life to your years.

Now, if the passions had no hold on us, a week and a hundred years would amount to the same.

Do you wish people to think well of you? Don't speak well of yourself.

We sail within a vast sphere, ever drifting in uncertainty, driven from end to end.
