Memento Mori—the ancient practice of reflection on mortality that goes back to Socrates, who said that the proper practice of philosophy is “about nothing else but dying and being dead.”
Remember you die, because what is mortality without the contemplation of death.
and thyself, too, shall die;
but one thing I know that never dies
the tales of the one who died.
