The articles in this volume celebrate the work of Steven Burns. Versions of the articles were presented originally at two sessions organized in Burns's honour at the 2022 meeting of the Atlantic Regional Philosophers’ Association (ARPA), held at Dalhousie University in Halifax. This introduction presents a brief academic biography and summarizes each of the contributions. The articles, by Michael Hymers, Robbie Moser and Darren Bifford, Alice MacLachlan, Jason Holt, and Warren Heiti, address perennial themes in philosophy, such as self-knowledge, attention, friendship, interpretation, and judgement. The collection concludes with some last words by Burns himself.

I survey my career in philosophy, which encompasses 44 years of teaching in Halifax, but begins in London, England with a thesis on self-deception. I describe a practice of using works of literature as a guide to conceptual analysis, and pause in Vienna to translate On Last Things (Weininger, 2001). A line of Wittgenstein's is the basis for reflections on the concept of a Last Judgement. I discuss in some detail a paper of mine for the Atlantic Region Philosophers’ Association in 2018, “One Last Thing,” which takes as its basis The Sense of an Ending, a novel by Julian Barnes. I conclude with some claims about Wittgenstein's relation to religion. I add an Appendix, in which I comment briefly on each of the other articles that make up this symposium.

The suppression thesis is the theological claim that theistic non-belief results from culpable mistreatment of one's knowledge of God or one's evidence for God. The thesis is a traditional one but unpopular today. This article examines whether it can gain new credibility from the philosophy of self-deception and from the cognitive science of religion. The thesis is analysed in terms of the intentionalist and the non-intentionalist model of self-deception. The first proposed model views non-belief as intentional suppression of one's implicit knowledge of God. It is less feasible psychologically but has a good theological fit with Paul's and Calvin's versions of the thesis. This model also helps the argument for the culpability of non-belief. The second model views suppression as a process of subconscious motivated reasoning driven by a desire to avoid an uncomfortable truth. It fits Pascal's view that one's desire for or against God determines whether one sees general revelation as providing sufficient evidence for God. There is some empirical and anecdotal evidence for both models, but obvious cases of non-resistant non-belief present a major problem for the suppression thesis. Also, it is hard to see what might motivate anyone to deceive oneself about God's existence.

There are two main meanings in Kant’s concept of moral certainty (moralische Gewissheit, certitudo moralis): first, it applies to the kind of certainty embodied in rational faith in the existence of God and a future life; second, it applies to the conscientiousness (Gewissenhaftigkeit) required of an agent in the practice of moral judgement. Despite the growing attention to Kant’s theory of conscience and his concept of conscientiousness, this article is the first to discuss ‘moral certainty’ as the aim of ‘conscientiousness’ and to highlight the relevance of both notions in regard to moral education and the purposes of Kant’s ethical doctrines of method.

Saul Smilansky presents us with a puzzle which, in combination with a small number of premises, is supposed to generate a reversal of Pascal's wager: the wagerer should bet on a secular lifestyle, and reject religion, as the surest way of pleasing God (if God exists). In this article, we argue that the puzzle, once unpacked, isn't particularly puzzling, that the premises aren't true, and that Smilansky's wager is open to both reductio and a reversal of its own.

I defend the thesis that friendship can constitutively require epistemic irrationality against a recent, forceful challenge, raised by proponents of moral and pragmatic encroachment. Defenders of the “encroachment strategy” argue that exemplary friends who are especially slow to believe that their friends have acted wrongly are simply sensitive to the high prudential or moral costs of falsely believing in their friends’ guilt. Drawing on psychological work on epistemic motivation (and in particular on the notion of “need for closure”), I propose a different picture of what friendship requires in the doxastic realm. I argue that contrary to what the encroachment strategy suggests, exemplary friends’ belief formation ought not be guided by a concern with accuracy or error avoidance, but instead by a need to avoid a “specific closure” – namely, a need to avoid concluding in their friends’ guilt. I propose that exemplary friendship often generates a defeasible, doxastic obligation to exemplify such a need, despite its inherent corrupting effects on exemplary friends’ epistemic faculties.

Both poor insight and depressive symptomatology are common features of schizophrenia that may be independent of positive and negative symptoms. Forty-six patients with DSM-III-R schizophrenia were evaluated for level of insight (schedule for unawareness of mental disorder), depression (Calgary depression scale for schizophrenia, Beck depression inventory), and self-deception or denial (balanced inventory of desirable responding). Patients with a greater unawareness of their illness had relatively less depressive symptomatology and relatively greater self-deception. This relationship was particularly strong for unawareness of the social consequences of having a mental disorder. These results suggest that the presence of depressive symptomatology in schizophrenia is related to the level of insight, and contingent at least in part on the absence of self-deception as a denial defense.

The self-deception debate often appears polarized between those who think that self-deceivers intentionally deceive themselves (‘intentionalists’), and those who think that intentional actions are not significantly involved in the production of self-deceptive beliefs at all. In this paper I develop a middle position between these views, according to which self-deceivers do end up self-deceived as a result of their own intentional actions, but where the intention these actions are done with is not an intention to deceive oneself. This account thus keeps agency at the heart of self-deception, while also avoiding the paradox associated with other agency-centered views.

In my paper, I shall briefly explore a philosophy of performative speech acts, which is in line with Charles Taylor’s investigation into the human linguistic capacity. It complements the full shape of the linguistic capacity and gives an account of how reason enters thinking due to language. Language creates openness to reasons by, as I emphasize, means of a critique of self-deception, which could be accomplished by linguistic capacity.

Little extended attention has been given to Kant’s notion of self-conceit (Eigendünkel), though it appears throughout his theoretical and practical philosophy. Authors who discuss self-conceit often describe it as a kind of imperiousness or arrogance in which the conceited agent seeks to impose selfish principles upon others, or sees others as worthless. I argue that these features of self-conceit are symptoms of a deeper and more thoroughgoing failure. Self-conceit is best described as the tendency to insist upon one’s own theoretical or practical conclusions at any cost, while still wanting to appear – to oneself or to others – as though one is abiding by the constraints of theoretical or practical reason. Self-conceit is thus less centrally the tendency to impose one’s will or inclinations upon others, and more centrally the tendency to reconstruct evidence and rationalize so that one may be convinced of one’s own virtue. While the conceited agent may ultimately impose her judgement upon others, she does so in order to preserve her delusion of virtue.

In this article we argue that self-deception evolved to facilitate interpersonal deception by allowing people to avoid the cues to conscious deception that might reveal deceptive intent. Self-deception has two additional advantages: It eliminates the costly cognitive load that is typically associated with deceiving, and it can minimize retribution if the deception is discovered. Beyond its role in specific acts of deception, self-deceptive self-enhancement also allows people to display more confidence than is warranted, which has a host of social advantages. The question then arises of how the self can be both deceiver and deceived. We propose that this is achieved through dissociations of mental processes, including conscious versus unconscious memories, conscious versus unconscious attitudes, and automatic versus controlled processes. Given the variety of methods for deceiving others, it should come as no surprise that self-deception manifests itself in a number of different psychological processes, and we discuss various types of self-deception. We then discuss the interpersonal versus intrapersonal nature of self-deception before considering the levels of consciousness at which the self can be deceived. Finally, we contrast our evolutionary approach to self-deception with current theories and debates in psychology and consider some of the costs associated with self-deception.

From an evolutionary standpoint, a default presumption is that true beliefs are adaptive and misbeliefs maladaptive. But if humans are biologically engineered to appraise the world accurately and to form true beliefs, how are we to explain the routine exceptions to this rule? How can we account for mistaken beliefs, bizarre delusions, and instances of self-deception? We explore this question in some detail. We begin by articulating a distinction between two general types of misbelief: those resulting from a breakdown in the normal functioning of the belief formation system (e.g., delusions) and those arising in the normal course of that system's operations (e.g., beliefs based on incomplete or inaccurate information). The former are instances of biological dysfunction or pathology, reflecting “culpable” limitations of evolutionary design. Although the latter category includes undesirable (but tolerable) by-products of “forgivably” limited design, our quarry is a contentious subclass of this category: misbeliefs best conceived as design features. Such misbeliefs, unlike occasional lucky falsehoods, would have been systematically adaptive in the evolutionary past. Such misbeliefs, furthermore, would not be reducible to judicious – but doxastically1 noncommittal – action policies. Finally, such misbeliefs would have been adaptive in themselves, constituting more than mere by-products of adaptively biased misbelief-producing systems. We explore a range of potential candidates for evolved misbelief, and conclude that, of those surveyed, only positive illusions meet our criteria.

Self-deception is made unnecessarily puzzling by the assumption that it is an intrapersonal analog of ordinary interpersonal deception. In paradigmatic cases, interpersonal deception is intentional and involves some time at which the deceiver disbelieves what the deceived believes. The assumption that self-deception is intentional and that the self-deceiver believes that some proposition is true while also believing that it is false produces interesting conceptual puzzles, but it also produces a fundamentally mistaken view of the dynamics of self-deception. This target article challenges the assumption and presents an alternative view of the nature and etiology of self-deception. Drawing upon empirical studies of cognitive biases, it resolves familiar “paradoxes” about the dynamics of self- deception and the condition of being self-deceived. Conceptually sufficient conditions for self-deception are offered and putative empirical demonstrations of a kind of self-deception in which a subject believes that a proposition is true while also believing that it is false are criticized. Self-deception is neither irresolvably paradoxical nor mysterious, and it is explicable without the assistance of mental exotica. The key to understanding its dynamics is a proper appreciation of our capacity for acquiring and retaining motivationally biased beliefs.
