There’s a famous quote in George Orwell’s 1984: “Who controls the past controls the future. Who controls the present controls the past.” Orwell understood how important knowledge of history is and how it can be manipulated by the powerful to serve their interests. If the past disappears down the memory hole society is at risk. History is not some neutral ideologically-free zone. It is a highly contested battlefield. The contents of textbooks are subject to partisan bias, often tilting to the right. Inadequate history textbooks help produce adults who can’t distinguish evidence from opinion, fact from fiction. Progressive voices such as Frederick Douglass, Emma Goldman, and Dorothy Day are often omitted from textbooks or just appear without context. James Loewen said, “Telling the truth about the past helps cause justice in the present. Achieving justice in the present helps us tell the truth about the past.”
