Merry Gravmas by James P. Hogan (Minds, Machines and Evolution, 1988) sets up, in its short introduction, a world two thousand years from now, where Christmas Day is used to celebrate the birth of Isaac Newton, “who came to save us all from irrationality”. It is told from the point of view of a Chinese family (Europe is in ruins), and is moderately amusing.
