Well, we now have such a photograph... Has any new idea been let loose? It certainly has. You will have noticed how suddenly everybody has become seriously concerned to protect the natural environment... It seems to me more than a coincidence that this awareness should have happened at exactly the moment man took his first step into space.

The chance that higher life forms might have emerged through evolutionary processes is comparable with the chance that a tornado sweeping through a junk yard might assemble a Boeing 747 from the material therein.

Space isn't remote at all. It's only an hour's drive away if your car could go straight upwards.

Once a photograph of the Earth, taken from outside, is available, we shall, in an emotional sense, acquire an additional dimension.

It is in the world of ideas and in the relation of his brain to the universe itself that the superiority of Man lies. The rise of Man may justly be described as an adventure in ideas.

There is a coherent plan to the universe, though I don't know what it's a plan for.

A junkyard contains all the bits and pieces of a Boeing 747, dismembered and in disarray. A whirlwind happens to blow through the yard. What is the chance that after its passage a fully assembled 747, ready to fly, will be found standing there? So small as to be negligible, even if a tornado were to blow through enough junkyards to fill the whole Universe.
