Glacier  

Over the years, people I’ve met have often asked me what I’m working on, and I’ve usually replied that the main thing was a book about Dresden.
I said that to Harrison Starr, the movie-maker, one time, and he raised his eyebrows and inquired, ‘Is it an anti-war book?’
‘Yes,’ I said. ‘I guess.’
‘You know what I say to people when I hear they're writing anti-war books?’
‘No. What do you say, Harrison Starr?’
‘I say, “Why don't you write an anti-glacier book instead?”’
What he meant, of course, was that there would always be wars, that they were as easy to stop as glaciers. I believe that too. --Slaughterhouse-Five, 1969, Kurt Vonnegut

"I waited and waited, but the glacier did not move. Night was coming on, the darkness began to gather—still we did not budge. It occurred to me then, that there might be a time-table in Baedeker; it would be well to find out the hours of starting. I called for the book—it could not be found. Bradshaw would certainly contain a time-table; but no Bradshaw could be found." --A Tramp Abroad (1880) by Mark Twain
