We call attention to certain cases of epistemic akrasia, arguing that they support belief-credence dualism. Belief-credence dualism is the view that belief and credence are irreducible, equally fundamental attitudes. Consider the case of an agent who believes p, has low credence in p, and thus believes that they shouldn’t believe p. We argue that dualists, as opposed to belief-firsters (who say credence reduces to belief) and credence-firsters (who say belief reduces to credence) can best explain features of akratic cases, (...) including the observation that akratic beliefs seem to be held despite possessing a defeater for those beliefs, and that, in akratic cases, one can simultaneously believe and have low confidence in the very same proposition.

Many views rely on the idea that it can never be rational to have high confidence in something like, “P, but my evidence doesn’t support P.” Call this idea the “Non-Akrasia Constraint”. Just as an akratic agent acts in a way she believes she ought not act, an epistemically akratic agent believes something that she believes is unsupported by her evidence. The Non-Akrasia Constraint says that ideally rational agents will never be epistemically akratic. In a number of recent (...) papers, the Non-Akrasia Constraint has been called into question. The goal of this paper is to defend it... for the most part. (shrink)

According to John Broome, akrasia consists in a failure to intend to do something that one believes one ought to do, and such akrasia is necessarily irrational. In fact, however, failing to intend something that one believes one ought to do is only guaranteed to be irrational if one is certain of a maximally detailed proposition about what one ought to do; if one is uncertain about any part of the full story about what one ought to do, (...) it could be perfectly rational not to intend to do something that one believes one ought to do. This paper seeks to remedy this problem, by proposing an anti-akrasia principle that covers cases of uncertainty (as well as cases of such complete certainty). It is argued that this principle is in effect the fundamental principle of practical rationality. (shrink)

One way of discerning what sort of control we have over our mental lives is to look at cases where that control is not exercised. This is one reason why philosophers have taken an interest in the phenomenon of akrasia, in an agent's ability to do, freely and deliberately, something that they judge they ought not to do. Akrasia constitutes a failure of control but not an absence of control. The akratic agent is not a compulsive; an akratic (...) agent has the ability to control their action, to make it conform to their judgement, but they fail to exercise that ability. They freely and deliberately give in to temptation. (shrink)

According to one influential view, advanced by Jonathan Adler, David Owens and Susan Hurley, epistemic akrasia is impossible because when we form a full belief, any apparent evidence against that belief loses its power over us. Thus theoretical reasoning is quite unlike practical reasoning, in that in the latter our desires continue to exert a pull, even when they are outweighed by countervailing considerations. I call this argument against the possibility of epistemic akrasia the subsumption view. The subsumption (...) view accurately reflects the nature of reasoning in a range of everyday cases. But, as I show, it is quite false with regard to controversial questions, like philosophical disputes. In these, evidence against our best judgments continues to exert a hold on us. Thus, the claimed disanalogy between practical and theoretical reasoning fails. (shrink)

de Anima III.10 characterizes akrasia as a conflict between phantasia (“imagination”) on one side and rational cognition on the other: the akratic agent is torn between an appetite for what appears good to her phantasia and a rational desire for what her intellect believes good. This entails that akrasia is parallel to certain cases of perceptual illusion. Drawing on Aristotle's discussion of such cases in the de Anima and de Insomniis , I use this parallel to illuminate the (...) difficult discussion of akrasia in Nicomachean Ethics VII.3, arguing that its account of akrasia as involving ignorance is compatible with, and in fact crucially supplements, the more straightforward account we find elsewhere in the corpus of akrasia as a struggle between desires. (shrink)

In this paper I challenge the commonly held view that Plato acknowledges and accepts the possibility of akrasia in the Laws. I offer a new interpretation of the image of the divine puppet in Book 1 - the passage often read as an account of akratic action -- and I show that it is not intended as an illustration of akrasia at all. Rather, it provides the moral psychological background for the text by illustrating a broader notion of (...) self-rule as a virtuous condition of the soul (and lack of self-rule as a vicious condition). I examine key discussions in the Laws in order to show how Plato makes use of this broader notion of self-rule throughout the dialogue, and I argue that nothing Plato says in the Laws commits him to the possibility of akrasia. One significant consequence of my interpretation of the puppet passage is that it avoids the need to posit developmentalism in Plato's late views about the embodied human soul, as some recent commentators have done: the moral psychology of the Laws, on my reading, is not incompatible with the Republic's tripartite theory of the soul. (shrink)

Though it seems rather surprising in retrospect, until about twenty-five years ago no philosopher in the Western tradition had explicitly formulated the question whether there could be an epistemic analogue to practical akrasia. Also surprisingly, despite the prima facie analogue with practical akrasia (the possibility of which is not much disputed), much of the recent work on this question has defended the rather bold view that epistemic akrasia is impossible. While the arguments purporting to show the impossibility (...) of epistemic akrasia have been criticized by some, I propose instead to make a head-on attack and defend the substantive view that epistemic akrasia is possible — indeed, actual. This leaves for another day the project of diagnosing exactly where the arguments for the impossibility of epistemic akrasia go wrong. Here, I content myself with trying to show that they must go wrong, since — as I will argue — epistemic akrasia is possible. (shrink)

According to the Fragmentation Analysis, epistemic akrasia is a state of conflict between beliefs formed by the linguistic and non-linguistic belief-formation systems, and epistemic akrasia is irrational because it is a state of conflict between beliefs so formed. I argue that there are cases of higher-order epistemic akrasia, where both beliefs are formed by the linguistic belief-formation system. Because the Fragmentation Analysis cannot accommodate this possibility, the Fragmentation Analysis is incorrect. I consider three objections to the possibility (...) of higher-order epistemic akrasia. Along the way, I offer a revision of the Fragmentation Analysis that can allow for the possibility of higher-order akrasia while avoiding the problems I point out for the original view. (shrink)

It is commonly thought that one is irrationally akratic when one believes one ought to F but does not intend to F. However, some philosophers, following Robert Audi, have argued that it is sometimes rational to have this combination of attitudes. I here consider the question of whether rational akrasia is possible. I argue that those arguments for the possibility of rational akrasia advanced by Audi and others do not succeed. Specifically, I argue that cases in which an (...) akratic agent acts as he has most reason to act, and cases in which an akratic agent achieves a kind of global coherence he wouldn’t have achieved had he instead formed intentions in line with his best judgment, do not establish the possibility of rational akrasia. However, I do think that rational akrasia is possible, and I present two arguments for this thesis. The first argument involves a case in which one is incapable of revising one’s belief about what one ought to do, where one also acknowledges this belief to be insufficiently supported by the evidence. The second argument involves a case in which one rationally believes that one ought to have an akratic combination of attitudes. (shrink)

This essay provides a novel argument for impurism, the view that certain non-truth-relevant factors can make a difference to a belief's epistemic standing. I argue that purists, unlike impurists, are forced to claim that certain ‘high-stakes’ cases rationally require agents to be akratic. Akrasia is one of the paradigmatic forms of irrationality. So purists, in virtue of calling akrasia rationally mandatory in a range of cases with no obvious precedent, take on a serious theoretical cost. By focusing on (...) akrasia, and on the nature of the normative judgments involved therein, impurists gain a powerful new way to frame a core challenge for purism. They also gain insight about the way in which impurism is true: my argument motivates the claim that there is moral encroachment in epistemology. (shrink)

The idea that conscious control, or more specifically akratic wrongdoing, is a necessary condition for blameworthiness has durable appeal. This position has been explicitly championed by volitionist philosophers, and its tacit influence is broadly felt. Many responses have been offered to the akrasia requirement espoused by volitionists. These responses often take the form of counterexamples involving blameworthy ignorance: i.e., cases where an agent didn’t act akratically, but where they nevertheless seem blameworthy. These counterexamples have generally led to an impasse (...) in the debate, with volitionists maintaining that the ignorant agents are blameless. In this paper, I explore a different sort of counterexample: I consider agents who have acted akratically, but whose very conscious awareness of their wrongdoing complicates their blameworthiness. I call these cases of “complex akrasia,” and I suggest that they are a familiar aspect of moral life. I interpret these cases as supporting non-volitionist accounts, and particularly Quality of Will accounts. (shrink)

The present article focuses on the issue of ignoring conversational partners in favor of one’s phone, or what has also become known as phubbing. Prior research has shown that this behavior is associated with a host of negative interpersonal consequences. Since phubbing by definition entails adverse effects, however, it is interesting to explore why people continue to engage in this hurtful behavior: Are they unaware that phubbing is hurtful to others? Or do they simply not care? Building on interviews with (...) students in a Danish business college, the article reveals a pronounced discrepancy in young people’s relationship to phubbing: While they emphatically denounce phubbing as both annoying and disrespectful, they readily admit to phubbing others. In other words, they often act against their own moral convictions. Importantly, participants describe this discrepancy as a result of an unintentional inclination to divert attentional engagement. On the basis of these results, the article develops the notion of digital akrasia, which can be defined as a tendency to become swept up by ones digital devices in spite of better intentions. It is proposed that this phenomenon may be the result of bad technohabits. Further implications are discussed. (shrink)

The author demonstrates that certain forms of irrationality - incontinent action and self-deception - which many philosophers have rejected as being logically or psychologically impossible, are indeed possible.

In this article, I develop an Aristotelian account of akrasia as a primary failure of intentional agency in contrast to a phenomenon I refer to as ‘ordinary weakness of will’: I argue that ordinary weakness of will is best understood as a secondary failure of intentional agency, that to tackle akrasia.

It is natural to think that rationality imposes some relationship between what a person believes, and what she believes about what she’s rational to believe. Epistemic akrasia—for example, believing P while believing that P is not rational to believe in your situation—is often seen as intrinsically irrational. This paper argues otherwise. In certain cases, akrasia is intuitively rational. Understanding why akratic beliefs in those case are indeed rational provides a deeper explanation how typical akratic beliefs are irrational—an explanation (...) that does not flow from akrasia per se. This understanding also allows us to diagnose where general anti-akratic arguments go wrong. We can then see why even principles designed to allow only moderate akrasia fail, and also why recognizing the possibility of rational akratic beliefs does not call for finding some other epistemic defect in agents who believe akratically. Believing akratically, in itself, is nothing to apologize for. (shrink)

This article aims to shed light on both the foundations and the consistency of the position regarding akrasia Xenophon attributes to Socrates in the Memorabilia. As does Plato's Socrates, Xenophon's Socrates maintains that akrasia is impossible in the presence of knowledge. On the other hand, he differs from the platonic Socrates by granting to enkrateia, instead of knowledge, the role of foundation for virtue. If enkrateia is the very condition for acquiring knowledge and virtue, consequently the responsibility for (...) countering akrasia falls to enkrateia. (shrink)

It seems that epistemically rational agents should avoid incoherent combinations of beliefs and should respond correctly to their epistemic reasons. However, some situations seem to indicate that such requirements cannot be simultaneously satisfied. In such contexts, assuming that there is no unsolvable dilemma of epistemic rationality, either (i) it could be rational that one’s higher-order attitudes do not align with one’s first-order attitudes or (ii) requirements such as responding correctly to epistemic reasons that agents have are not genuine rationality requirements. (...) This result doesn’t square well with plausible theoretical assumptions concerning epistemic rationality. So, how do we solve this puzzle? In this paper, I will suggest that an agent can always reason from infallible higher-order reasons. This provides a partial solution to the above puzzle. (shrink)

This article offers an account of akrasia as a primary failure of intentional agency in contrast to a recent account of weakness of will, developed by Richard Holton, that also points to a kind of failure of intentional agency but presents this as both separate from akrasia and more fundamental than it. Drawing on Aristotle’s work, it is argued that the failure of intentional agency articulated by the concept of akrasia is the central case, whereas the phenomenon (...) Holton’s account is after, referred to as ‘ordinary weakness of will’, is best understood as an unsuccessful attempt to tackle akrasia and, more specifically, a secondary failure of intentional agency.

Joseph Raz and Sergio Tenenbaum argue that the Guise of the Good thesis explains both the possibility of practical reason and its unity with theoretical reason, something Humean psychological theories may be unable to do. This paper will argue, however, that Raz and Tenenbaum face a dilemma: either the version of the Guise of the Good they offer is too strong to allow for weakness of will, or it will lose its theoretical advantage in preserving the unity of reason.

In this paper I will present a puzzle about epistemic akrasia, and I will use that puzzle to motivate accepting some non-standard views about the nature of epistemological judgment. The puzzle is that while it seems obvious that epistemic akrasia must be irrational, the claim that epistemic akrasia is always irrational amounts to the claim that a certain sort of justified false belief—a justified false belief about what one ought to believe—is impossible. But justified false beliefs seem (...) to be possible in any domain, and it’s hard to see why beliefs about what one ought to believe should be an exception. I will argue that when we get clearer about what sort of psychological state epistemic akrasia is, we can resolve the puzzle in favor of the intuitive view that epistemic akrasia is always irrational.

There is widespread disagreement about whether epistemic akrasia is possible. This paper argues that the possibility of epistemic akrasia follows from a traditional rationalist conception of epistemic critical reasoning, together with considerations about the fallibility of our capacities for reasoning. In addition to defending the view that epistemic akrasia is possible, we aim to shed light on why it is possible. By focusing on critical epistemic reasoning, we show how traditional rationalist assumptions about our core cognitive capacities (...) help to explain the possibility of epistemic akrasia. (shrink)

In Nicomachean Ethics VII, Aristotle offers an account of akrasia that purports to salvage the kernel of truth in the Socratic paradox that people act against what is best only through ignorance. Despite Aristotle’s apparent confidence in having identified the sense in which Socrates was right about akrasia, we are left puzzling over Aristotle’s own account, and the extent to which he agrees with Socrates. The most fundamental interpretive question concerns the sense in which Aristotle takes the akratic (...) to be ignorant. The received view in the literature has been the intellectualist interpretation, which takes akratic agents to be so ignorant of the wrongness of what they do as to be unaware of it. In recent decades, many scholars have identified serious problems in this interpretation and have moved towards the non-intellectualist reading, the strong version of which takes clearheaded akrasia to be possible. There is, however, a glaring shortage of discussion of the difficulties facing the strong... (shrink)

Epistemic akrasia arises when one holds a belief even though one judges it to be irrational or unjustified. While there is some debate about whether epistemic akrasia is possible, this paper will assume for the sake of argument that it is in order to consider whether it can be rational. The paper will show that it can. More precisely, cases can arise in which both the belief one judges to be irrational and one’s judgment of it are epistemically (...) rational in the sense that both are supported by sufficient evidence.

This paper presents an account of akrasia, drawn from the work of William James, that sees akrasia as neither a rational failing (as with most philosophical accounts) nor a moral failing (as with early Christian accounts), but rather a necessary by-product of our status as biological beings. By examining James’s related accounts of motivation and action, I argue that akratic actions occur when an agent attempts to act against her settled habits, but fails to do so. This makes (...) akrasia a product of the agent’s practical failure to adequately structured her environment to bring about her desired action. Akratic action performs the vital function of revealing to the agent the exact point at which her cognitive effort was insufficient for bringing about her intended action. It also reveals that future improvement is within her control. As such, akratic action is the very foundation of James’s meliorism. (shrink)

Pristine belief/desire psychology has its limitations. Recognizing this, some have attempted to fill various gaps by adding more of the same, but at higher levels. Thus, for example, second-order desires have been imported into a more stream- lined view to explicate such important notions as freedom of the will, personhood, and valuing. I believe that we need to branch out as well as up, augmenting a familiar 'philosophical psychology' with psychological items that are irreducible to beliefs and desires (for support, (...) see Mele 1987 and 1992). That theme will be left largely in the background here, however. The issue to be explored is a narrower one: the place of higher-order desires in a proper conception of continent and incontinent behavior. My guiding question is whether an action's counting as continent or incontinent depends upon the agent's having at the time a pertinent higher-order desire. The answer that I shall defend is, in a word, 'No.'. (shrink)

The standard account of weakness of will identifies it with akrasia, that is, with action against one's best judgment. Elsewhere I have argued that weakness of will is better understood as over-readily giving up on one's resolutions. Many cases of weak willed action will not be akratic: in over-readily abandoning a resolution an agent may well do something that they judge at the time to be best. Indeed, in so far as temptation typically gives rise to judgment shift -- (...) to a tendency to change one's judgment so that one values the tempting option as the best -- weak willed action will typically be akratic. But conversely, strong willed action now looks as though it will be akratic. I argue though that it need not be, once we distinguish between actual judgment, and dispositions to judge. Within this framework, the issue of inverse akrasia looks rather different. I argue that whilst Huckleberry Finn plausibly does show weakness of will in abandoning his resolve to turn Jim in, it is far from clear that he is akratic: a point brought out well in Twain's later additions to the text. Whilst cases of inverse akrasia are clearly theoretically possible, I suggest that, given cognitive dissonance mechanisms, they are unlikely to be very common. (shrink)

This paper argues that Epictetus’ ethics involves three features which are also present in Aristotle’s discussion of akrasia in the Nicomachean Ethics: 1) A major problem for agents is when they fail to render a universal premise effective at motivating a particular action in accordance with that premise. 2) There are two reasons this occurs: Precipitancy and Weakness. 3) Precipitancy and Weakness can be prevented by gaining a fuller understanding of our beliefs and commitments. This comparison should make clear (...) that akrasia is certainly not absent from Epictetus. Rather a very Aristotelian understanding of why we fail to act in accordance with what we take to be in our own best interests remains at the center of his ethics. (shrink)

Epistemically akratic agents believe both p and that believing p is irrational for them. Some of the costs of thinking that epistemic akrasia can be rational are clear. It is hypocritical, and outright weird, to have beliefs that we consider irrational, let alone to reason with or act on those beliefs. However, as Maria Lasonen-Aarnio (2020) and Brian Weatherson (2019) have argued, the weirdness of akrasia does not obviously tell against its rationality. Here I argue that views permitting (...) epistemic akrasia fare worse than previously thought. These views imply that we should sometimes have beliefs that we know for certain are either irrational or false. And while having a belief that we know to be irrational is straightforwardly irrational, the additional possibility that the belief may be false cannot make having it any more rational. (shrink)

Examines what is necessary for a group to constitute an agent that can display akrasia, and what steps such a group might take to establish self‐control. The topic has some interest in itself, and the discussion suggests some lessons about how we should think of akrasia in the individual as well as in the collective case. Under the image that the lessons support, akrasia is a sort of constitutional disorder: a failure to achieve a unity projected in (...) the avowal of agency. This image fits well with the constitutional model of the soul in Plato's Republic. (shrink)

Epistemic akrasia can be rational. I consider a lonely pragmatist who believes that her imaginary friend doesn’t exist, and also believes on pragmatic grounds that she should believe in him. She rationally believes that her imaginary friend doesn’t exist, rationally follows various sources of evidence to the view that she should believe in him to end her loneliness, and rationally holds these attitudes simultaneously. Evidentialism suggests that her ambivalent epistemic state is rational, as considerations grounded in the value of (...) truth justify her beliefs. (shrink)

Just as the existence of practical akrasia has been treated as important evidence for the existence of our practical agency, the alleged absence of epistemic akrasia—cases in which a believer believes some proposition contrary to her considered judgments about what she has most reason to believe—has recently been marshaled as grounds for skepticism about the existence of similar forms of epistemic agency. In this paper, I defend the existence of epistemic agency against such objections. Rather than argue against (...) the impossibility of epistemic akrasia, I argue that the impossibility of epistemic akrasia is actuallycompatible withthe existence of epistemic agency. The crucial mistake, I argue, is that skeptics about epistemic agency are failing to distinguish carefully between differences in the structure of believing and acting and differences in the structure of normative reasons to believe and normative reasons to act. I show that once these ‘environmental’ differences are properly distinguished, we can see that absence of epistemic akrasia provides no reason to doubt that practical and epistemic agency are on a par with one another.

This paper discusses practical akrasia from the perspective of the sophisticated form of moral subjectivism that can be derived from Nuno Venturinha’s (2018) remarks on moral matters.

Epistemic akrasia is the phenomenon of voluntarily believing what you think you should not. Whether epistemic akrasia is possible is a matter of controversy. I argue that at least some people who suffer from obsessive–compulsive disorder are genuinely epistemically akratic. I advance an account of epistemic akrasia that explains the clinical data and provides broader insight into the nature of doxastic attitude‐formation.

Offers a distinctive take on the motivation problem by way of an analysis of akrasia and the nature of rationality.

Argues that we do not act intentionally ‘under the guise of the good.’ This makes it hard to explain why akrasia is distinctively irrational; but this is no objection, since it is just as hard to explain on the opposing view. Ends with a problem of akrasia for ethical rationalists.

The standard economic theory of choice is extended to accommodate a particular form of akratic choice. The empirical content of the new theory is fully characterized. A characterization of revealed akratic choice, in terms of observable choice only, is also provided. These results are consistent with the viewpoint that akrasia is a concept that can be empirically substantiated.

It is argued that the recent revival of theakrasia problem in the philosophy of mind is adirect, albeit unforeseen result of the debate onaction explanation in the philosophy of science. Asolution of the problem is put forward that takesaccount of the intimate links between the problem ofakrasia and this debate. This solution is basedon the idea that beliefs and desires have degrees ofstrength, and it suggests a way of giving a precisemeaning to that idea. Finally, it is pointed out thatthe (...) solution captures certain intuitions of bothSocrates and Aristotle. (shrink)

This paper contrasts a picoeconomic approach to theexplanation of akrasia with Davidson's divided-mind approach and defends theformer in a wider context. The distinctive merits of a picoeconomic model of mindlie in the following aspects: First, it relies on a scientifically well-groundeddiscovery about motivational dynamics of animals for its explanation of preference change,which elucidates or materializes some philosophers' speculations both about thepossible mismatch between valuation and motivation and about the relevance of temporalfactors to akrasia. Second, it grounds the necessity (...) of endogenous higher-order constraints,expressible in forms of judgment, in an intrapersonal dynamic process of interactivefirst-order temporary preferences. Thus the motivational basis for the normativeconstruction of the rationality of `best judgment' can also be illuminated with this model. (shrink)
