Abstract

The philosopher Quassim Cassam has described a concept called ‘Conspiracy Theories’ (capitalized) that includes several ‘special features’ that distinguish such theories from other theories positing conspiracies. Conspiracy Theories, he argues, are unlikely to be true. Indeed, he implies that they are, as a class of ideas, so unlikely to be true that we are justified in responding to them by criticizing the ideology they are (presumed to be) associated with, rather than engaging them solely on their individual epistemic merits. This article argues that Cassam’s ‘special features’ are ambiguous. Under some interpretations, they are not epistemically problematic. Under other interpretations, they do not fairly describe many of the theories Cassam treats as examples of Conspiracy Theories. In the end, there seems to be no interpretation of these features that would justify the inference that theories Cassam treats as Conspiracy Theories, including JFK Conspiracy Theories, can be reasonably dismissed on account of having these features.
