We are concerned that life is short and that its end approaches. But there is consolation in the contrary thought that we are getting through this life, that a time will come when we can lay down its burdens of pain, disappointment, ignorance, and moral failure. The end is the end of the goods of this life but also the end of its evils. And this whether the end is final or a new beginning.
So death, where is thy sting? If this world is but a shadow-play of phenomena, full of sound and fury, signifying nothing; if all the world's a stage in the theater of the absurd, then to be quit of it is no great loss. But if it is prelude, then new adventures await and you can look forward to them. To live well one must hope, both in this life and beyond it.
But suppose you believe that this world is ultimately real, and that life in it is unqualifiedly good. Then you have a problem. For then death is a great calamity: it deprives you irrevocably of the ultimate in reality and value.
The solution to the problem is to abandon the twin presupposition that this world is the ne plus ultra of being and value and that life in it is unqualifiedly good. There are fairly weighty reasons for both abandonments.
What I don't understand is the attitude of Philip Larkin on Death. He seems in the grip of the twin presupposition.
