Greene takes it for granted, and here the great majority of physicists agree with him, that the division of physics into separate theories for large and small objects is unacceptable. ... Greene believes that there is an urgent need to find a theory of quantum gravity that applies to large and small objects alike. ... As a conservative, I do not agree that a division of physics into separate theories for large and small is unacceptable. ... The essence of any theory of quantum gravity is that there exists a particle called the graviton ... I looked at various possible ways of detecting gravitons and did not find a single one that worked. Because of the extreme weakness of the gravitational interaction, any putative detector of gravitons has to be extremely massive. If the detector has normal density, most of it is too far from the source of gravitons to be effective, and if it is compressed to a high density around the source it collapses into a black hole. There seems to be a conspiracy of nature to prevent the detector from working.

Additional quotes by Freeman Dyson

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.

... informed me that my theological standpoint is Socinian. ...If I remember correctly what Hartshorne said, the main tenant ...is that God is neither omniscient nor omnipotent. He learns and grows as the universe unfolds. ...I merely find ...[this doctrine] congenial, and consistent with common sense. I do not make any clear distinction between mind and God. God is what mind becomes when it has passed beyond our comprehension. ...either a world-soul or a collection of world-souls. We are the chief inlets of God on this planet at... present... We may later grow with him as he grows, or we may be left behind. If... left behind, it is an end. If we keep growing, it is a beginning.
