No one can have a peaceful life who thinks too much about lengthening it.

Life is short and art is long.

The first petition that we are to make to Almighty God is for a good conscience, the next for health of mind, and then of body.

Let the weary at length possess quiet rest.

We are born to lose and to perish, to hope and to fear, to vex ourselves and others; and there is no antidote against a common calamity but virtue; for the foundation of true joy is in the conscience.

Live among others as if God beheld you; speak to God as if others were listening.

We learn not for life but for the debating-room.
