"So long as our textbooks hide from us the roles that people of color have played in exploration, from at least 6000 BC to the twentieth century, they encourage us to look to Europe and its extensions as the seat of all knowledge and intelligence. So long as they say "discover," they imply that whites are the only people who really matter. So long as they simply celebrate Columbus, rather than teach both sides of his exploit, they encourage us to identify with white Western exploitation rather than study it."
