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.

I'm just a propagandist and a propagandist doesn't have to know what he is talking about, just so he talks about it most convincingly.

I have tried at times to place humans in perspective against the vastness of universal time and space. I have been concerned with where we, as a race, may be going and what may be our purpose in the universal scheme — if we have a purpose. In general, I believe we do, and perhaps an important one.

This is the very center of everything there is. A huge black hole eating up the galaxy. The end of everything.

Here lies one from a distant star, but the soil is not alien to him, for in death he belongs to the universe.

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.

My reluctance to use alien invasion is due to the feeling that we are not likely to be invaded and taken over. 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. Further than this, there should be no economic necessity of its doing so. By the time it was able to go into deep space, it must have arrived at an energy source which would not be based on planetary natural resources.
