An old quote, by any other name, is still enjoyable

Be kind to colleagues, ruthless with theories, is a good rule. A scientific theory isn’t merely idle speculation, it’s a verbal picture of how things might work, how a system in nature might organize things – atom and molecules, species and ecosystems. But old paleontological theories too often aren’t treated roughly enough. Old theories – like the reptilian nature of dinosaurs – are accepted like old friends of the family. You don’t yell at old Aunt Cecilia. So hundred-year-old dinosaur theories live on without being questioned, and too often they are assumed to be totally correct. Even when such theory is caught in an error, it’s likely to be excused.
