Abstract
Many intellectuals scoff at what they call “conspiracy theories.” But two Harvard law professors, Cass Sunstein (now working for the Obama administration) and Adrian Vermeule, go further. They argue in the Journal of Political Philosophy that groups that espouse such theories ought to be infiltrated and undermined by government agents and allies. While some may find this proposal appalling (as indeed we all should), others may find the argument plausible, especially if they have been swayed by the notion that conspiracy theories (or a definable subset thereof), by their nature, somehow or another, do not warrant belief. I will argue that Sunstein and Vermeule’s proposal not only conflicts with the values of an open society, but is also epistemically indefensible. In making my case, I will adopt their favored example, counter-narratives about 9/11.
