"Crooked people deceive themselves in order to deceive others; in this way the world comes to ruin." This quote from a medieval Confucianist expresses the ethical danger of self-deception. My paper examines the psychological proclivity for self-deception and argues that it lies behind much social and interpersonal injustice. I review Hitler's Mein Kampf, as a premiere example of such cognitive duplicity, and Socratic dialectic, as an example of the cognitive hygiene necessary to combat it. I conclude that a robust educational (...) program of Socratic-style critical thinking is crucial to the furtherance of a just society. (shrink)

A distinctive feature of Juan Comesaña's epistemological account is the possibility of an agent possessing a false proposition as evidence. Comesaña argues that there are a number of theoretical virtues of his account once we accept this possibility, however, one might expect that there are particular vices of his account as well. Littlejohn and Dutant (2021) claim that a reflective agent who accepts Comesaña's view is rationally compelled to update their credences differently than unreflective agents, or else they will be (...) guilty of a problematic kind of doublethink: evidence in general can be false, but my evidence is never false. I argue that parallel reasoning applies to any epistemological view that says that it is possible for a rational agent to be wrong about what their evidence is. When a rational agent reflectively accepts that they could be wrong about their evidence they are rationally compelled to update their credences differently than unreflective agents, or else they will be guilty of a problematic kind of doublethink: even though rational agents in general are wrong about their evidence, I'm never wrong about my evidence. Reflecting on a particular challenge to Comesaña's view ultimately reveals a general challenge to fallibilism. (shrink)

Unlike mainstream Cyrenaics, the Annicereans deny that friendship is chosen only because of its usefulness. Instead, the wise person cares for her friend and endures pains for him because of her goodwill and love. Nonetheless, the Annicereans maintain that your own pleasure is the telos and that a friend’s happiness isn’t intrinsically choiceworthy. Their position appears internally inconsistent or to attribute doublethink to the wise person. But we can avoid these problems. We have good textual grounds to attribute to (...) the Annicereans a doctrine of “non-hedonic habits,” which allows them to abandon psychological hedonism while still maintaining hedonism regarding well-being.
