“Both religion and science require a belief in God. For believers, God is in the beginning, and for physicists He is at the end of all considerations… To the former He is the foundation, to the latter, the crown of the edifice of every generalized world view.”
Scientific Autobiography and Other Papers as translated by F. Gaynor (1949), p. 184
Variant translations:
Both religion and science need for their activities the belief in God, and moreover God stands for the former in the beginning, and for the latter at the end of the whole thinking. For the former, God represents the basis, for the latter – the crown of any reasoning concerning the world-view.
Religion und Naturwissenschaft (1958 edition), p. 27, as quoted in 50 Nobel Laureates and Other Great Scientists Who Believe in God (2008) by Tihomir Dimitrov http://nobelist.tripod.com/sitebuildercontent/sitebuilderfiles/50-nobelists.pdf
While both religion and natural science require a belief in God for their activities, to the former He is the starting point, to the latter the goal of every thought process. To the former He is the foundation, to the latter the crown of the edifice of every generalized world view.

Progress In Religion (2000)
Context: To talk about the end of science is just as foolish as to talk about the end of religion. Science and religion are both still close to their beginnings, with no ends in sight. Science and religion are both destined to grow and change in the millennia that lie ahead of us, perhaps solving some old mysteries, certainly discovering new mysteries of which we yet have no inkling.

Context: Our god's name is Abraxas and he is God and Satan and he contains both the luminous and the dark world. Abraxas does not take exception to any of your thoughts, any of your dreams. Never forget that. But he will leave you once you've become blameless and normal. Then he will leave you and look for a different vessel in which to brew his thoughts.
