Robert Greene quote

“What prevents people from learning, even something as difficult as Pirahã, is not the subject itself—the human mind has limitless capabilities—but rather certain learning disabilities that tend to fester and grow in our minds as we get older. These include a sense of smugness and superiority whenever we encounter something alien to our ways, as well as rigid ideas about what is real or true, often indoctrinated in us by schooling or family. If we feel like we know something, our minds close off to other possibilities. We see reflections of the truth we have already assumed. Such feelings of superiority are often unconscious and stem from a fear of what is different or unknown. We are rarely aware of this, and often imagine ourselves to be paragons of impartiality.”
