mortality

"The time of a man's life is as a point; the substance of it ever flowing, the sense obscure; and the whole composition of the body tending to corruption."

"Remember how brief life is, how vast the universe. What is the fame of a man, or the power, or even the pain?"

"The perfection of character is this: to live each day as if it were your last, without frenzy, without apathy, without pretense."

"Death smiles at us all, but all a man can do is smile back."

"Every day is a step toward eternity."

"Let us prepare our minds as if we'd come to the very end of life. Let us postpone nothing."

"There is nothing after death, and death itself is nothing."
