The chain of life runs smoothly from one generation to the next and none of the links stand out except here and there a link one sees by accident.

Much of what we see in the universe ... starts out as imaginary. Often you must imagine something before you can come to terms with it.

Time is still the great mystery to us. It is no more than a concept; we don't know if it even exists.

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?

There is a plan, it seems to me, that reaches out of the electron to the rim of the universe and what this plan may be or how it came about is beyond my feeble intellect. But if we are looking for something on which to pin our faith- and, indeed, our hope- the plan might well be it. I think we have thought too small and have been too afraid.

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 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.
