A major problem posed by cases of self-deception concerns the inconsistent behavior of the self-deceived subject (SDS). How can this be accounted for, in terms of propositional attitudes and other mental states? In this paper, we argue that key problems with two recent putative solutions, due to Mele and Archer, are avoided by “the shifting view” that has been advanced elsewhere in order to explain cases where professed beliefs conflict with actions. We show that self-deceived agents may possess highly unstable (...) degrees of belief concerning the matters about which they are self-deceived. (shrink)

According to what I call the ‘Vagueness Thesis’ about belief, ‘believes’ is a vague predicate. On this view, our concept of belief admits of borderline cases: one can ‘half-believe’ something or be ‘in-between believing’ it. In this article, I argue that VT is false and present an alternative picture of belief. I begin by considering a case—held up as a central example of vague belief—in which someone sincerely claims something to be true and yet behaves in a variety of other (...) ways as if she believes that it is not. I argue that, even from the third-person perspective prioritised by proponents of VT, the case does not motivate VT. I present an alternative understanding of the case according to which the person in question believes as they say they do yet also has a belief-discordant implicit attitude otherwise. Moreover, I argue that, independently of the interpretation of any particular case, VT fails to accommodate the first-person perspective on belief. Belief is not only an item of one’s psychology that helps explain one’s behaviour; it is what one takes to be true. This fact about belief manifests itself in the nature of deliberation concerning whether to believe something and that of introspection regarding whether one believes something. Attending to these phenomena reveals that VT is not merely unmotivated, but untenable. (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.

Teresa believes in God. Maggie’s wife believes that the Earth is flat, and also that Maggie should be home from work by now. Anouk—a cat—believes it is dinner time. This dissertation is about what believing is: it concerns what, exactly, ordinary people are attributing to Teresa, Maggie’s wife, and Anouk when affirming that they are believers. Part I distinguishes the attitudes of belief that people attribute to each other (and other animals) in ordinary life from the cognitive states of belief (...) theoretically posited by (some) cognitive scientists. Part II defends the view that to have an attitude of belief is to live—to be disposed to act, react, think, and feel—in a pattern that an actual belief attributor identifies with taking the world to be some way. Drawing on scientific, scholarly, and literary sources of evidence, How Beliefs are like Colors provides a framework for research on belief across the humanities and sciences of the mind. (shrink)
