Can Anosognosia Vindicate Traditionalism about Self-Deception?

The traditional conception of self-deception takes it for an intrapersonal form of interpersonal deception. However, since the same subject is at the same time deceived and deceived, this means attributing the agent a pair of contradictory beliefs. In the course of defending a deflationary conception of self-deception, Mele (1997) has challenged traditionalists to present convincing evidence that there are cases of self-deception in which what he calls the dual belief-requirement is satisfied. Levy (2009) has responded to this challenge affirming that there is at least one real cases of self-deception that meets this requirement, namely, that of anosognosia. In this family of conditions, the patient apparently believes that there is nothing wrong with her while, at the same time, providing behavioral cues that indicate that the patient is somehow aware of his disease. If Levy is right, then traditionalism about self-deception could be vindicated, after having been widely abandoned due to its need to postulate exotic mental processes in order to make sense of the attribution of contradictory beliefs. In this paper, I assess whether Levy’s response to Mele’s challenge is successful by analyzing his interpretation of the empirical evidence to which he appeals. Finally, I attack the cogency of the underlying commitments about the nature of folk psychology to which one is required to defer in order to draw from conflicting evidence the attribution of contradictory beliefs.
