This is written in the elder days as the Earth rides close to the rim of eternity, edging nearer to the dying Sun, into which her two inner companions of the solar system have already plunged to a fiery death. The Twilight of the Gods is history; and our planet drifts on and on into that oblivion from which nothing escapes, to which time itself may be dedicated in the final cosmic reckoning.
Clifford D. SimakIt 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
Clifford D. SimakWe came into a homeless frontier, a place where we were not welcome, where nothing that lived was welcome, where thought and logic were abhorrent and we were frightened, but we went into this place because the universe lay before us, and if we were to know ourselves, we must know the universe
Clifford D. SimakI have not long to live. I have lasted more than a man's average allotted span, and while I still am hale and hearty, I know full well the hand of time , while it may miss a man at one reaping, will get him at the next.
Clifford D. SimakCould that have been what happened to the human race - a willing perversity that set at naught all human values which had been so hardly won and structured in the light of reason for a span of more than a million years?
Clifford D. SimakMy 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.
