from Journey to the End of the Night by Louis Ferdinand Celine

Travel is useful, it exercises the imagination.All the rest is disappointment and fatigue. Our journey is entirely imaginary. That is its strength. It goes from life to death. People, animals, cities, things, all are imagined. It's a novel, just a fictitious narrative. Littre says so, and he's never wrong. And besides, anyone can do as much. You just have to close your eyes. It's on the other side of life.
