Famous quotes containing the word episodes:
“What is a novel if not a conviction of our fellow-men’s existence strong enough to take upon itself a form of imagined life clearer than reality and whose accumulated verisimilitude of selected episodes puts to shame the pride of documentary history?”
—Joseph Conrad (1857–1924)
“Twenty or thirty years ago, in the army, we had a lot of obscure adventures, and years later we tell them at parties, and suddenly we realize that those two very difficult years of our lives have become lumped together into a few episodes that have lodged in our memory in a standardized form, and are always told in a standardized way, in the same words. But in fact that lump of memories has nothing whatsoever to do with our experience of those two years in the army and what it has made of us.”
—Václav Havel (b. 1936)
