“Man has many wishes that he does not really wish to fulfil, and it would be a misunderstanding to suppose the contrary. He wants them to remain wishes, they have value only in his imagination; their fulfilment would be a bitter disappointment to him. Such a desire is the desire for eternal life. If it were fulfilled, man would become thoroughly sick of living eternally, and yearn for death. In reality man wishes merely to avoid a premature, violent or gruesome death. Everything has its measure, says a pagan philosopher; in the end we weary of everything, even of life; a time comes when man desires death. Consequently there is nothing frightening about a normal, natural death, the death of a man who has fulfilled himself and lived out his life.”
