I raise three puzzles concerning self-deception: (i) a conceptual paradox, (ii) a dilemma about how to understand human cognitive evolution, and (iii) a tension between the fact of self-deception and Davidson’s interpretive view. I advance solutions to the first two and lay a groundwork for addressing the third. The capacity for self-deception, I argue, is a spandrel, in Gould’s and Lewontin’s sense, of other mental traits, i.e., a structural byproduct. The irony is that the mental traits of which self-deception is (...) a spandrel/byproduct are themselves rational. (shrink)

This paper aims to offer an alternative to the existing philosophical theories of self-deception. It describes and motivates a teleofunctional theory that models self-deception on the subintentional deceptions perpetrated by non-human organisms. Existing theories of self-deception generate paradoxes, are empirically implausible, or fail to account for the distinction between self-deception and other kinds of motivated irrationality. Deception is not a uniquely human phenomenon: biologists have found that many non-human organisms deceive and are deceived. A close analysis of the pollination strategy (...) of the mirror orchid (Ophrys speculum) provides the basis for an analysis of non-human deception as subintentionally purposive. This teleofunctional analysis is then used as the basis for a theory of self-deception that accounts for its normative and purposive features without defaulting to intentionalism. The teleofunctional theory accounts for distinction between self-deception and phenomena such as wishful thinking in an empirically plausible manner. Three objections to the theory are considered and rejected. (shrink)

According to doxastic accounts of self-deception, self-deception that P yields belief that P. For doxastic accounts, the self-deceiver really believes what he, in self-deception, professes to believe. I argue that doxastic accounts are contradicted by a phenomenon that often accompanies self-deception. This phenomenon – which I term ‘secondary deception’ – consists in the self-deceiver's defending his professed (deceit-induced) belief to an audience by lying to that audience. I proceed to sketch an alternative, non-doxastic account of how we should understand self-deception (...) in terms of the self-deceiver's misrepresentation of himself as believing that P. (shrink)

The essential task of the investigation of self-deception is nothing more than establishing the boundary of it, herein known as the distinction problem of self-deception. Such a boundary is necessary for distinguishing the phenomenon of self-deception from other similar phenomena, especially wishful thinking, and sheds light on the future research of other theoretical questions posed by the phenomenon. Although philosophers have reached a vague consensus on certain necessary elements involved in the phenomenon of self-deception, there is no general agreement on (...) their details, leading to a lack of canonical literature regarding the question of what makes self-deception a unique phenomenon. In this thesis, I begin by attempting to re-establish the initial definition of self-deception by illustrating the vague consensus in the current discussion of self-deception. Then, several representative views are examined to uncover the reason for their failure to capture the distinction between self-deception and other kinds of irrationality. These findings are then used to clarify what the basic structure of self-deception should be. Finally, I develop an account revealing that the distinction problem is related to the study of the necessary attitude involved in self-deception. My analysis shows that a special kind of instability inherent in the necessary attitude involved in self-deception is the key to establishing self-deception as a distinctive case of motivated irrationality.
