"I can't go back," said Towser. "Nor I," said Fowler. "They would turn me back into a dog," said Towser. "And me," said Fowler, "back into a man." - Clifford D. Simak

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.

The alien stood in shadow and he looked, Enoch thought, more than ever like the cruel clown. His lithe, flowing body had the look of smoked, tanned buckskin. The patchwork color of his hide seemed to shine with a faint luminescence and the sharp, hard angles of his face, the smooth baldness of his head, the flat, pointed ears pasted tight against the skull lent him a vicious fearsomeness.

I have become a student of the sky and know all the clouds there are and have firmly fixed in mind the various hues of blue that the sky can show—the washed-out, almost invisible blue of a hot, summer noon; the soft robin’s egg, sometimes almost greenish blue of a late springtime evening, the darker, almost violet blue of fall.

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. There is a plan, it seems to me, that reaches out from 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...
