Truth itself is a common good. Through history, one of the first things tyrants have done is attack independent truth-tellers—philosophers (Plato), scientists (Galileo), and the free and independent press—thereby confusing the public and substituting their own “facts.” Without a shared truth, democratic deliberation is hobbled. “Alternative facts” are an open invitation to what George Orwell described as “doublethink,” in which the public is so confused it cannot recall the past, assess the present, or contemplate the future.
