Facing up to non-being enables us to put our life into perspective, see it in its entirety, and thereby lend it a sense of direction and unity. If the ultimate source of anxiety is fear of the future, the future ends in death; and if the ultimate source of anxiety is uncertainty, death is the only certainty. It is only by facing up to death, accepting its inevitability, and integrating it into life that we can escape from the pettiness and paralysis of anxiety, and, in so doing, free ourselves to make the most out of our lives and out of ourselves.
