"What do you mean by faith? Is faith enough for Man? Should he be satisfied with faith alone? Is there no way of finding out the truth? Is the attitude of faith, of believing in something for which there can be no more than philosophic proof, the true mark of a Christian?"

"It seems to me, thinking of it, that there must be some universal plan which set in motion the orbiting of the electrons about the nucleus and the slower, more majestic orbit of the galaxies about one another to the very edge of space."

"It would seem to me that by the time a race has achieved deep space capability it would have matured to a point where it would have no thought of dominating another intelligent species."

"It was a place without a single feature of the space-time matrix that he knew. It was a place where nothing yet had happened - an utter emptiness. There was neither light nor dark: there was nothing here but emptiness."

"Without consciousness and intelligence, the universe would lack meaning."

"Must faith be exactly that, the willingness and ability to believe in the face of a lack of evidence? If one could find the evidence, would then the faith be dead?"

"My reluctance to use alien invasion is due to the feeling that we are not likely to be invaded and taken over."

"And time itself? Time was a never-ending medium that stretched into the future and the past - except there was no future and no past, but an infinite number of brackets, extending either way, each bracket enclosing its single phase of the Universe."

"It is only of life on Earth, however, that one can speak with any certainty. It seems to me that all life on Earth, the sum total of life upon the Earth, has purpose."

"If the means were available, we could trace our ancestry - yours and mine - back to the first blob of life-like material that came into being on the planet."
