Seneca · On conquering the conqueror
Letters 30.16
Bassus kept saying: “It is due to our own fault that we feel this torture, because we shrink from dying only when we believe that our end is near at hand.” But who is not near death? It is ready for us in all places and at all times. “Let us consider,” he went on to say, “when some agency of death seems imminent, how much nearer are other varieties of dying which are not feared by us.”
