Scientific Autobiography and Other Papers as translated by F. Gaynor (1949), p. 184
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.
