Famous quotes containing the words real and/or space:
“I do not hesitate to read ... all good books in translations. What is really best in any book is translatable—any real insight or broad human sentiment.”
—Ralph Waldo Emerson (1803–1882)

Into space that is quite economical,
But the good ones I’ve seen
So seldom are clean
And the clean ones so seldom are comical.”
