"I was not brought up in a religious milieu but was (like most Danes) born into the Lutheran-Protestant church. Religion did not play much of a role and when I was in my early twenties I left the church; not because I became an atheist but just because of lack of interest and a certain dislike of organized religion as practiced in my country. My interest in religion is of relatively new date and mostly a result of my studies in history of science which showed how important Christian religion has been for the development of science (and at some stage also Islam). Especially after I turned toward history of cosmology I began thinking about religion in connection with, for example, the perennial question of the origin of the universe. Although I do not believe in traditional religious dogmas I have sympathy and respect for religious thought whereas I have no sympathy for hard-core atheism and materialism. Somehow, it seems to me, there must be something above and beyond the physical universe, a mystical spirit or divine principle. If this principle is called God, I believe in God. But this god has no interest at all in human beings. In a sense, my kind of religiosity is somewhat the same as the one Einstein expressed on various occasions."
