I have frequently been questioned, especially by women, of how I could reconcile family life with a scientific career. Well, it has not been easy.
I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.
I assert that the cosmic religious experience is the strongest and noblest driving force behind scientific research.
How can this cosmic religious experience be communicated from man to man, if it cannot lead to a definite conception of God or to a theology? It seems to me that the most important function of art and of science is to arouse and keep alive this feeling in those who are receptive.
For scientific endeavor is a natural whole the parts of which mutually support one another in a way which, to be sure, no one can anticipate.
Everyone who is seriously involved in the pursuit of science becomes convinced that some spirit is manifest in the laws of the universe, one that is vastly superior to that of man. In this way the pursuit of science leads to a religious feeling of a special sort, which is surely quite different from the religiosity of someone more naive.
Every scientific fulfillment raises new questions; it asks to be surpassed and outdated.[Jede wissenschaftliche “Erfüllung” bedeutet neue “Fragen” und will “überboten” werden und veralten.]
