The issue whether psychopathic offenders are practically rational has attracted philosophical attention. The problem is relevant in theoretical discussions on moral psychology and in those concerning the appropriate social response to the crimes of these individuals. We argue that classical and current experiments concerning the instrumental learning in psychopaths cannot directly support the conclusion that they have impaired instrumental rationality, construed as the ability for transferring the motivation by means-ends reasoning. In fact, we defend the different claim (...) that these experiments appear to show that psychopaths in certain circumstances are not aware of the relevant means for their ends. Moreover, we suggest how further empirical research could help to settle the issue. (shrink)

This paper argues that instrumental rationality is more permissive than expected utility theory. The most compelling instrumentalist argument in favour of separability, its core requirement, is that agents with non-separable preferences end up badly off by their own lights in some dynamic choice problems. I argue that once we focus on the question of whether agents’ attitudes to uncertain prospects help define their ends in their own right, or instead only assign instrumental value in virtue of the (...) outcomes they may lead to, we see that the argument must fail. Either attitudes to prospects assign non-instrumental value in their own right, in which case we cannot establish the irrationality of the dynamic choice behaviour of agents with non-separable preferences. Or they don’t, in which case agents with non-separable preferences can avoid the problematic choice behaviour without adopting separable preferences. (shrink)

This paper draws some bold conclusions from modest premises. My topic is an old one, the Neohumean view of practical rationality. First, I show that this view consists of two independent claims, instrumentalism and subjectivism. Most critics run these together. Instrumentalism is entailed by many theories beyond Neohumeanism, viz. by any theory that says rational actions maximize something. Second, I give a new argument against instrumentalism, using simple counterexamples. This argument systematically undermines consequentialism and rational choice theory, I show, (...) using detailed examples of their many social science applications. There is no obvious fix. (shrink)

This is a short introductory article. I focus on three questions: What is instrumental rationality? What are the principles of instrumental rationality? Could instrumental rationality be all of practical rationality?

In the dynamic choice literature, temptations are usually understood as temporary shifts in an agent’s preferences. What has been puzzling about these cases is that, on the one hand, an agent seems to do better by her own lights if she does not give into the temptation, and does so without engaging in costly commitment strategies. This seems to indicate that it is instrumentally irrational for her to give into temptation. On the other hand, resisting temptation also requires her to (...) act contrary to the preferences she has at the time of temptation. But that seems to be instrumentally irrational as well. I here consider the two most prominent types of argument why resisting temptation could nevertheless be instrumentally rational, namely two-tier and intra-personal cooperation arguments. I establish that the arguments either fail or are redundant. In particular, the arguments fail under the pervasive assumption in both decision theory and the wider literature on practical rationality that the agent’s preferences over the objects of choice are themselves the standard of instrumental rationality. And they either still fail or they become redundant when we give up that assumption. (shrink)

The goal of this article is to show that instrumental rationality and utility that have been used in economics for many years does not work well. What is presented in the article is how significant the influence of utilitarianism has been on economics and why the economists get rid of humans’ goals and motivations. It is shown in the article that the human who decides in present is absolutely different from the human who decides over time. Many economists (...) neglected this problem because they wanted to have an effective and simple model. Becker’s economic method is presented as a dead end to which economics has been brought to. It is impossible to connect different selves of one human being by using the utility measure. The works of Schelling and J.S. Mill are used to explain this impossibility. The conclusion of this article is that instrumental rationality and utility have affected economics significantly. But, this simplified view on human nature is no longer valid. Hence, economics needs to think not only about the means but also about the human goals. Economics needs to rebuff relativism and show people how to achieve well-being. If we want to help people with their self-governance, we will have to choose reason over emotions. (shrink)

Standard decision theory, or rational choice theory, is often interpreted to be a theory of instrumental rationality. This dissertation argues, however, that the core requirements of orthodox decision theory cannot be defended as general requirements of instrumental rationality. Instead, I argue that these requirements can only be instrumentally justified to agents who have a desire to have choice dispositions that are stable over time and across different choice contexts. Past attempts at making instrumentalist arguments for the (...) core requirements of decision theory fail due to a pervasive assumption in decision theory, namely the assumption that the agent’s preferences over the objects of choice – be it outcomes or uncertain prospects – form the standard of instrumental rationality against which the agent’s actions are evaluated. I argue that we should instead take more basic desires to be the standard of instrumental rationality. But unless agents have a desire to have stable choice dispositions, according to this standard, instrumental rationality turns out to be more permissive than orthodox decision theory. (shrink)

When we ask a decision maker to express her preferences, it is typically assumed that we are eliciting a pre-existing set of preferences. However, empirical research has suggested that our preferences are often constructed on the fly for the decision problem at hand. This paper explores the ramifications of this empirical research for our understanding of instrumental rationality. First, I argue that these results pose serious challenges for the traditional decision-theoretic view of instrumental rationality, which demands (...) global coherence amongst all of one's beliefs and desires. To address these challenges, I first develop a minimal notion of instrumental rationality that issues in localized, goal-relative demands of coherence. This minimal conception of instrumental rationality is then used to offer a more sophisticated account of the global aspects of instrumental rationality. The resulting view abandons all-or-nothing assessments of rationality and allows us to evaluate decision makers as being rational to varying degrees. My aim is to propose a theory that is both psychologically and normatively plausible. (shrink)

In Rational Powers in Action, Sergio Tenenbaum sets out a new theory of instrumental rationality that departs from standard discussions of means-ends coherence in the literature on structural rationality in at least two interesting ways: it takes intentional action (as opposed to intention) to be what puts in place the relevant instrumental requirements, and it applies to both necessary and non-necessary means. I consider these two developments in more detail. On the first, I argue that Tenenbaum’s (...) theory is too narrow since there could be instrumental irrationality with respect to an intention to X even if one is not yet engaged in any relevant intentional action. On the second, I argue against Tenenbaum’s claim that “an agent is instrumentally irrational if she knowingly fails to pursue some sufficient means to an end she is pursuing.”. (shrink)

Neo-Humean instrumentalist theories of reasons for acting have been presented with a dilemma: either they are normatively trivial and, hence, inadequate as a normative theory or they covertly commit themselves to a noninstrumentalist normative principle. The claimed result is that no purely instrumentalist theory of reasons for acting can be normatively adequate. This dilemma dissolves when we understand what question neo-Humean instrumentalists are addressing. The dilemma presupposes that neo-Humeans are attempting to address the question of how to act, 'simpliciter'. Instead, (...) they are evaluating actions from the agent's normative perspective.

This essay goes through Frederick 2015 (the critique) in some detail, responding to the various paraphrases and criticisms therein. It is argued that in each case the critique is mistaken about what Lester 2012 (Escape from Leviathan: EfL) says, or about what the critique presents as a sound criticism, or both. Introduction: the three problems with the critique and the philosophical problem that EfL is attempting to solve. “Abstract”: the critique’s confusion about EfL’s aprioristic theory of instrumental rationality. (...) There are then detailed replies (too many and too diverse to summarise) to quotations from the critique’s confused interpretations and criticisms under the following headings (quoted from the critique): “2. Instrumental Rationality”; 3. Weakness of Will”; “4. Desires and Values”; “5. Free Will”; “6. Self-Interest”; “7. Maximisation”; “8. Morals”. Finally, in “9. Conclusion”, the philosophical problem for economics is briefly restated. The philosophical interpretation of homo economicus in EfL (as with its overall philosophical theory of libertarianism) has yet to be given adequate critical consideration. (shrink)

In Chapter 2 of Escape from Leviathan, Jan Lester defends two hypotheses: that instrumental rationality requires agents to maximise the satisfaction of their wants and that all agents actually meet this requirement. In addition, he argues that all agents are self-interested (though not necessarily egoistic) and he offers an account of categorical moral desires which entails that no agent ever does what he genuinely feels to be morally wrong. I show that Lester’s two hypotheses are false because they (...) cannot accommodate weakness of will, because they are inconsistent with agency, which requires free will, because ends, obligations and values cannot be reduced to desires, and because maximisation is often not possible. Further, Lester’s claim that agents are self-interested is vacuous, his attempted reduction of moral behaviour to want-satisfaction fails, and his contention, that agents always do what they genuinely think to be morally required, seems untenable. A defence of freedom that depends on homo economicus is far from promising. (shrink)

I want to examine the implications of a metaphysical thesis which is presupposed in various objections to Rawls' theory of justice.Although their criticisms differ in many respects, they concur in employing what I shall refer to as the continuity thesis. This consists of the following claims conjointly: (1) The parties in the original position (henceforth the OP) are, and know themselves to be, fully mature persons who will be among the members of the well-ordered society (henceforth the WOS) which is (...) generated by their choice of principles of justice. (2) The OP is a conscious event among others, integrated (compatibly with the constraints on knowledge and motivation imposed on the parties) into the regular continuity of experience that comprises each of their ongoing constitutes lives. (3) The parties in the OP thus are, and regard themselves as, psychologically continuing persons, partially determined in personality and interests by prior experiences, capable of recollection and regret concerning the past, anticipation and apprehensiveness regarding the future, and so on. Although the continuity thesis as stated above is not at odds with any of the conditions that define the OP, its exegetical validity is a matter for discussion. I shall be concerned to argue that if it is indeed contained in or a consequence of Rawls' theory, then it casts into doubt the capacity of the OP to generate or justify any principles of justice at all. On the other hand, if the continuity thesis is viewed as dispensable and unnecessary to the Rawlsian enterprise, then Rawls is correct in maintaining the irrelevance of the question of personal identity to the construction of his moral theory. In this case, the contract-theoretic, instrumentalist justification for the two principles of justice (henceforth the 2PJ) needs to be supplanted by a modified conception of wide reflective equilibrium. The considerations that form the bulk of this discussion then may be understood as providing a rationale for Rawls' recent revisions in the model of justification on which his theory of justice rests, and for his increasing emphasis on us as moral mediators between the OP and the WOS. Now I want to consider the question of whether or not, given the textual evidence, anything like the continuity thesis is stated or implied by Rawls, and what problems for his theory, if any, turn on a positive or negative answer to this question. -/- .

To the normal reasons that we think can justify one in preferring something, x (namely, that x has objectively preferable properties, or has properties that one prefers things to have, or that x's obtaining would advance one's preferences), I argue that it can be a justifying reason to prefer x that one's very preferring of x would advance one's preferences. Here, one prefers x not because of the properties of x, but because of the properties of one's having the preference (...) for x. So-revising one's preferences is rational in paradoxical choice situations like Kavka's Deterrence Paradox. I then try to meet the following objections: that this is stoicist, incoherent, bad faith; that it conflates instrumental and intrinsic value, gives wrong solutions to the problems presented by paradoxical choice situations, entails vicious regresses of value justification, falsifies value realism, makes valuing x unresponsive to x's properties, causes value conflict, conflicts with other standards of rationality, violates decision theory, counsels immorality, makes moral paradox, treats value change as voluntary, conflates first- and second-order values, is psychologically unrealistic, and wrongly presumes that paradoxical choice situations can even occur.

This paper aims to address the question of how one ought to choose when one is uncertain about what outcomes will result from one’s choices, but when one can nevertheless assign probabilities to the different possible outcomes. These choices are commonly referred to as choices (or decisions) under risk. I assume in this paper that one ought to make instrumentally rational choices—more precisely, one ought to adopt suitable means to one’s morally permissible ends. Expected utility (EU) theory is generally accepted (...) as a normative theory of rational choice under risk, or, more specifically, as a theory of instrumental rationality. According to EU theory, when faced with a decision under risk, one ought to rank one’s options (from least to most choiceworthy) according to their EU and one ought to choose whichever option carries the greatest EU (or one of them in the event that several alternatives are tied). The EU of an option is a probability-weighted sum of each of its possible utilities. In this paper, I argue that EU theory is not the correct theory of instrumental rationality. In its place, I argue for a new theory of instrumental rationality, namely expected comparative utility (ECU) theory. I first show that for any choice option, a, and for any state of the world, G, the measure of the choiceworthiness of a in G is the comparative utility of a in G—that is, the difference in utility, in G, between a and whichever alternative to a carries the greatest utility in G. On the basis of this principle, I then argue, roughly speaking, that for any agent, S, faced with any decision under risk, S ought to rank her options (in terms of how choiceworthy they are) according to their ECU and S ought to choose whichever option carries the greatest ECU (or one of them in the event that several alternatives are tied). For any option, a, a’s ECU is a probability‐weighted sum of a’s comparative utilities across the various possible states of the world. In this paper, I show that in some commonplace decisions under risk, ECU theory delivers different verdicts from those of EU theory. (shrink)

This paper aims to contribute to the existing literature on normative cognition by providing a lineage explanation of human social norm psychology. This approach builds upon theories of goal-directed behavioral control in the reinforcement learning and control literature, arguing that this form of control defines an important class of intentional normative mental states that are instrumental in nature. I defend the view that great ape capacities for instrumental reasoning and our capacity (or family of capacities) for shared intentionality (...) coadapted to each other and argue that the evolution of this capacity has allowed the representation of social norms and the emergence of our capacity for normative guidance.

This thesis argues against the claim that AI is intelligent due to instrumental rationality, refuting both the reduction and emergence thesis. It contends that intelligence cannot be reduced to instrumental rationality and highlights issues in AI development and application. Instead, it proposes the motivation adaptation approach, where intelligence arises from network of generative motivations and the ability to adapt. This alternative is conceptually intuitive, avoids counterexamples, and provides clear development goals and foundations for ethical development. Thus, (...) the thesis concludes that AI's intelligence is not due to instrumental rationality but rather its motivation adaptability. (shrink)

Prima facie, we make successful decisions as we act on and intervene in the world day-to-day. Epistemologists are often concerned with whether rationality is involved in such decision-making practices, and, if so, to what degree. Some, particularly in the post-structuralist tradition, argue that successful decision-making occurs via an existential leap into the unknown rather than via any determinant or criterion such as rationality. I call this view radical voluntarism (RV). Proponents of RV include those who subscribe to a (...) view they call Critical Complexity (CC). In this paper, I argue that CC presents a false dichotomy when it conceives of rationality in Cartesian – i.e. ideal and transcendental – terms, and then concludes that RV is the proper alternative. I then outline a pragmatist rationality informed by recent work in psychology on bounded rationality, ecological rationality, and specifically embodied rationality. Such a pragmatist rationality seems to be compatible with the tenets of post-structuralism, and can therefore replace RV in CC. (shrink)

The thesis of instrumental convergence holds that a wide range of ends have common means: for instance, self preservation, desire preservation, self improvement, and resource acquisition. Bostrom contends that instrumental convergence gives us reason to think that "the default outcome of the creation of machine superintelligence is existential catastrophe". I use the tools of decision theory to investigate whether this thesis is true. I find that, even if intrinsic desires are randomly selected, instrumental rationality induces biases (...) towards certain kinds of choices. Firstly, a bias towards choices which leave less up to chance. Secondly, a bias towards desire preservation, in line with Bostrom's conjecture. And thirdly, a bias towards choices which afford more choices later on. I do not find biases towards any other of the convergent instrumental means on Bostrom's list. I conclude that the biases induced by instrumental rationality at best weakly support Bostrom's conclusion that machine superintelligence is likely to lead to existential catastrophe. (shrink)

What is structural rationality? Specifically, what is the distinctive feature of structural requirements of rationality? Some philosophers have argued, roughly, that the distinctive feature of structural requirements is coherence. But what does coherence mean, exactly? Or, at least, what do structuralists about rationality have in mind when they claim that structural rationality is coherence? This issue matters for making progress in various active debates concerning rationality. In this paper, I analyze three strategies for figuring out (...) what coherence means in the debates on structural rationality. I argue that these strategies face problems. (shrink)

I argue that emotions are not only rational in-themselves, strictly speaking, but they are also instrumentally rational, epistemically rational, and evaluatively rational. I begin with a discussion of what it means for emotions to be rational or irrational in-themselves, which includes the derivation of a criterion for the ontological rationality of emotions (CORe): For emotion or an emotion there exists some normative standard that is given by what emotion or an emotion is against which our emotional responses can be (...) judged or evaluated in virtue of the fact that our emotions manifest our rationality. I conclude with a brief discussion of the implications of this account. (shrink)

A response to review essays by Chrisoula Andreou, John Brunero, Matthias Haase, Erasmus Mayr, and Sarah Paul on Sergio Tenenbaum's _Rational Powers in Action_.

Suppose there are no in-principle restrictions on the contents of arbitrarily intelligent agents’ goals. According to “instrumental convergence” arguments, potentially scary things follow. I do two things in this paper. First, focusing on the influential version of the instrumental convergence argument due to Nick Bostrom, I explain why such arguments require an account of “promotion,” i.e., an account of what it is to “promote” a goal. Then, I consider whether extant accounts of promotion in the literature -- in (...) particular, probabilistic and fit-based views of promotion -- can be used to support dangerous instrumental convergence. I argue that neither account of promotion can do the work. The opposite is true: accepting either account of promotion undermines support for instrumental convergence arguments’ existentially worrying conclusions. The conclusion is that we needn’t be scared -- at least not because of arguments concerning instrumental convergence. (shrink)

David Gauthier suggested that all genuine moral problems are Prisoners Dilemmas (PDs), and that the morally and rationally required solution to a PD is to co-operate. I say there are four other forms of moral problem, each a different way of agents failing to be in PDs because of the agents’ preferences. This occurs when agents have preferences that are malevolent, self-enslaving, stingy, or bullying. I then analyze preferences as reasons for action, claiming that this means they must not target (...) the impossible, they must be able to be acted on in the circumstances, their targets must be attainable, and having the preferences must make their targets more likely. For groups of agents to have a distribution of preferences, their preferences must jointly have those four features, this imposing a kind of universalizability requirement on possible preferences. I then claim that, if all agents began with preferences satisfying these requirements, their preferences would not be of the morally problematic sort (on pain, variously, of circularity or contradiction in the specification of their targets). Instead, they would be either morally innocent preferences, or ones which put the agents in PDs. And it would then be instrumentally rational for the agents to prefer mutual co-operation. Thus if all agents initially had rationally permissible preferences and made rational choices of actions and preferences thereafter, they would never acquire immoral preferences, and so never be rationally moved to immoral actions. Further, the states of affairs such agents would be moved to bring about would be compatible with what Rawls’ agents would chose behind a veil of ignorance. Morality therefore reduces to rationality; necessarily, the actions categorically required by morality are also categorically required by rationality. (shrink)

Like all reasoning, practical reasoning is a process that takes a person from some of her existing mental states to a new mental state. Theoretical reasoning concludes in a belief; practical reasoning in an intention. This paper concentrates on instrumental reasoning, a species of practical reasoning in general. It argues that instrumental reasoning is correct if the content of the reasoning is a valid derivation, just as theoretical reasoning is correct if its content is a valid derivation. It (...) also argues that neither theoretical nor practical reasoning gives a reason for its conclusion. If a piece of reasoning is correct, it concludes in a state - a belief or an intention - that is rationally required by the states it is derived from, but rationally requiring a conclusion is not the same as giving a reason for it.

In Internal and External Reasons, Bernard Williams proposes a speculative argument for the idea that internal reasons are the only kind of normative reason, and that his counterfactual internal interpretation is the only truth condition for both kinds of reason-statements, H and S (H: “A has a reason to φ” and S: “There is a reason for A to φ”). He takes for granted, however, that internal and external reasons are the only possible kinds of normative reasons at work: his (...) argument is therefore question-begging against a externalism—yet this is only the lesser problem faced by reason internalism. The main problems for Williams’s argument are his semantical reduction of S to H (which entails his question-begging argument) and his ad hoc interpretation of H in terms of his stipulative account of internal reasons. The most serious problem for both reason internalism and reason externalism, however, is represented by certain moral counterintuitive examples on both sides, which could be considered as the central problem in the debate. In this thesis, after showing Williams’s argument to be question-begging, I first explain his failure to unify two irreducible questions (on the nature of normative reasons and on the nature of rationality) as well as to reduce the truth conditions of S to H. Then, through conceptual analysis, I show that William’s internalist interpretation of H is false, and that the commonsensical interpretation of H is one that I call contextual interpretation in terms of contextual reasons. Internal reasons are just one usage of H, and contextual reasons are the real rival to external reasons in the debate on normative reason. Secondly, I argue that the two distinct notions of rationality— relative (instrumental) rationality and absolute rationality—require two distinct truth conditions, and the central problem deals only with the absolute one. I hope to show that reason contextualism, defined in terms of contextual reasons (i.e., neither internal nor external reasons) provides us with the best explication of these two distinct notions of rationality, and that the contextual interpretation accommodates all the counterexamples associated with the central problem.

This paper concerns Warren Quinn’s famous “The Puzzle of the Self-Torturer.” I argue that even if we accept his assumption that practical rationality is purely instrumental such that what he ought to do is simply a function of how the relevant options compare to each other in terms of satisfying his actual preferences that doesn’t mean that every explanation as to why he shouldn’t advance to the next level must appeal to the idea that so advancing would be (...) suboptimal in terms of the satisfaction of his actual preferences. Rather, we can admit that his advancing would always be optimal, but argue that advancing isn’t always what he ought to do given that advancing sometimes fails to meet some necessary condition for being what he ought to do. For instance, something can be what he ought to do only if it’s an option for him. What’s more, something can be what he ought to do only if it’s something that he can do without responding inappropriately to his reasons—or, so, I argue. Thus, the solution to the puzzle is, I argue, to realize that, in certain circumstances, advancing is not what the self-torturer ought to do given that he can do so only by responding inappropriately to his reasons.

Contractarians aim to derive moral principles from the dictates of instrumental rationality alone. But it is well-known that contractarian moral theories struggle to identify normative principles that are both uniquely rational and morally compelling. Michael Moehler's recent book, *Minimal Morality* seeks to avoid these difficulties by developing a novel "two-level" social contract theory, which restricts the scope of contractarian morality to cases of deep and persistent moral disagreement. Yet Moehler remains ambitious, arguing that a restricted version of Kant's (...) categorical imperative is a uniquely rational principle of conflict resolution. We develop a formal model of Moehler's informal game-theoretic argument, which reconstructs a valid argument for Moehler's conclusion. This model, in turn, enables us to expose how a successful argument for Moehler's contractarian principle rests on assumptions that can only be justified by subtle yet significant departures from the standard conception of rationality. We thus extend our understanding of familiar contractarian difficulties by showing how they arise even if we restrict the scope of contractarian morality to a domain where its application seems both promising and necessary. We show that the problem lies not in contractarians' immodest ambitions but in the modest resources rationality can offer to satisfy them. (shrink)

Michael Huemer argues that cross-cultural convergence toward liberal moral values is evidence of objective moral progress, and by extension, evidence for moral realism. Nathan Cofnas claims to debunk Huemer’s argument by contending that convergence toward liberal moral values can be better explained by ‘two related non-truth-tracking processes’: self-interest and its long-term tendency to result in social conditions conducive to greater empathy. This article argues that although Cofnas successfully debunks Huemer’s convergence argument for one influential form of moral realism – Robust (...) Moral Realism, which holds that moral facts are non-natural, stance-independent normative facts – Cofnas’s debunking argument broadly supports a second type of moral realism: Enlightened Self-Interest Realism, the view that moral facts are reducible to stance-dependent requirements of instrumental (‘means-end’) rationality. Finally, this article argues that insofar as different Enlightened Self-Interest Realist theories make specific predictions about the intra- and inter-personal mechanisms behind moral convergence toward liberalism, empirical observations of cross-cultural convergence can provide independent support for Enlightened Self-Interest Realism. I conclude that this is an important mark in favor of Enlightened Self-Interest Realism over Robust Moral Realism. (shrink)

I make the observation that English sentences such as “You have reason to take the bus or to take the train” do not have the logical form that they superficially appear to have. I find in these sentences a conjunctive use of “or,” as found in sentences like “You can have milk or lemon in your tea,” which gives you a permission to have milk, and a permission to have lemon, though no permission to have both. I argue that a (...) confusion of genuine disjunctions with sentences of the above form has motivated the mistaken acceptance by some philosophers of principles like the one I call “Liberal Transmission.” This is the principle that if you have a reason to do something, then you have a reason to do it in each of the possible ways in which it can be done (though not more than one of them). I argue that Liberal Transmission and its close relatives are false. Wide-scope reasons are defined as reasons that have a conditional or other logical connective within the scope of the reason operator. For example, a wide-scope instrumental reason might be: reason(if you have an end, take the means). By refuting Liberal Transmission, I show that you could have wide-scope instrumental reasons like this while nevertheless lacking any narrow-scope reason to take the means, or narrow-scope reason to not have the end. This enables me to respond to two major objections to the wide-scope approach to the instrumental principle that have been developed by Joseph Raz and by Niko Kolodny. (shrink)

The last few decades have given rise to the study of practical reason as a legitimate subfield of philosophy in its own right, concerned with the nature of practical rationality, its relationship to theoretical rationality, and the explanatory relationship between reasons, rationality, and agency in general. Among the most central of the topics whose blossoming study has shaped this field, is the nature and structure of instrumental rationality, the topic to which Kant has to date (...) made perhaps the largest contribution, under the heading of his treatment of hypothetical imperatives.

The conception of rationality as Reasons Responsiveness (RR) has seen a revival in the literature. However, RR faces the indeterminacy problem: an agent may be instrumentally irrational even without failing to respond correctly to reasons. Reasons do not conclusively determine choice, but this should not be possible on RR. Hybrid Voluntarism (HV), which is supposed to apply particularly to cases where “reasons run out”, may be a solution. According to Ruth Chang, we can create will-based reasons through commitment if (...) the given reasons balance. HV is attractive since it seems to explain instrumental irrationality and preserve RR’s distinctive appeal. In this paper, I argue that HV fails to save RR in the face of indeterminacy. I first suggest that we distinguish between overdetermination and underdetermination and then show that while RR may solve the former, it fails with the latter. Therefore, we are still left with a case of irrationality without a failure to respond correctly to reasons. (shrink)

A précis of Sergio Tenenbaum's Rational Powers in Action (Oxford 2021).

Hume said that the reasons that determine the rationality of one's actions are the desires one has when acting: one's actions are rational iff they advance these desires. Thomas Nagel says this entails calling rational, actions absurdly conflicting in aims over time. For one might have reason, in one's current desires, to begin trying to cause states one foresees having reason, in one's foreseen desires, to prevent. Instead, then, real reasons must be timeless, so that current and foreseen reasons (...) cannot conflict. I say the desire theory does not have absurd consequences. A rational agent's desires would rationally evolve, never requiring actions conflicting in aims over time, except where it was instrumentally rational for her to change in her desires, whence such conflicts are rationally appropriate. Further, whatever sorts of things count as real reasons, since reasons can rationally require their own revision, they cannot be necessarily timeless. (shrink)

The orthodox theory of instrumental rationality, expected utility (EU) theory, severely restricts the way in which risk-considerations can figure into a rational individual's preferences. It is argued here that this is because EU theory neglects an important component of instrumental rationality. This paper presents a more general theory of decision-making, risk-weighted expected utility (REU) theory, of which expected utility maximization is a special case. According to REU theory, the weight that each outcome gets in decision-making is (...) not the subjective probability of that outcome; rather, the weight each outcome gets depends on both its subjective probability and its position in the gamble. Furthermore, the individual's utility function, her subjective probability function, and a function that measures her attitude towards risk can be separately derived from her preferences via a Representation Theorem. This theorem illuminates the role that each of these entities plays in preferences, and shows how REU theory explicates the components of instrumental rationality. (shrink)

In the eighth chapter of the Bodhicaryāvatāra, the Buddhist philosopher Śāntideva has often been interpreted as offering an argument that accepting the ultimate nonexistence of the self (anātman) rationally entails a commitment to altruism, the view that one should care equally for self and others. In this essay, I consider reconstructions of Śāntideva’s argument by contemporary scholars Paul Williams, Mark Siderits and John Pettit. I argue that all of these various reconfigurations of the argument fail to be convincing. This suggests (...) that, for Madhyamaka Buddhists, an understanding of anātman does not entail acceptance of the Bodhisattva path, but rather is instrumental to achieving it. Second, it suggests the possibility that in these verses, Śāntideva was offering meditational techniques, rather than making an argument for altruism from the premise of anātman. (shrink)

There are Humeans and unHumeans, disagreeing as to the validity of the Treatise’s ideas regarding practical reason, but not as to their importance. The basic argument here is that the enduring irresolution of their Hume centric debates has been fostered by what can be called the fallacy of normative monism, i.e. a failure to distinguish between two different kinds of normativity: empirical vs. rational. Humeans take the empirical normativity of personal desire to constitute the only real kind, while unHumeans insist (...) that only the objective rationality associated with categorical morality can provide reliable normative guidance. In turn, the failure to recognize the dual nature of normativity has helped engender motivational obscurantism: as essentially causal notions, motive and motivation obscure the rational processes that lie at the heart of deliberation and choice. Once it is realized that normativity takes two different forms, each with its own distinctive role, it becomes possible to mediate if not mitigate the differences between Humeans and unHumeans. Choice will be the key to understanding practical reasoning, and its analysis will provide the basis for a belief/desire model that upends conventional wisdom regarding motivation and desire.

This paper presents a unifying diagnosis of a number of important problems facing existing models of rational choice under moral uncertainty and proposes a remedy. I argue that the problems of (i) severely limited scope, (ii) intertheoretic comparisons, and (iii) 'swamping’ all stem from the way in which values are assigned to options in decision rules such as Maximisation of Expected Choiceworthiness. By assigning values to options under a given moral theory by asking something like ‘how much do I desire (...) this option, supposing this theory is true?’ rather than ‘how much value does this theory assign to this option?’ these problems can be avoided, while the appealing features of these accounts can be preserved. This amendment provides a role for the preferences, desires, or goals of rational agents that is curiously absent from the existing discussion of what individuals rationally ought to do when they are uncertain about what they morally ought to do.

Anscombe famously argues that to act intentionally is to act under a description, and that “it is the agent's knowledge of what he is doing that gives the descriptions under which what is going on is the execution of an intention.” Further, she takes ‘knows’ to mean that the agent can give these descriptions herself. It would seem to follow that animals cannot act intentionally. However, she denies this, insisting that although animals cannot express intentions, they can have them. But (...) how can we speak without equivocation of humans and animals acting intentionally while maintaining that linguistic expressibility is an essential characteristic of only human action? The human capacity for articulation, I argue, transforms animal intention in the following way: Whereas animal intentions are immanent in their behavior, human action is an actualization of the power to make judgments about what is to-be-done; this confers on human intentions a distinctive sort of independence from behavior.

Epistemic instrumentalists seek to understand the normativity of epistemic norms on the model practical instrumental norms governing the relation between aims and means. Non-instrumentalists often object that this commits instrumentalists to implausible epistemic assessments. I argue that this objection presupposes an implausibly strong interpretation of epistemic norms. Once we realize that epistemic norms should be understood in terms of permissibility rather than obligation, and that evidence only occasionally provide normative reasons for belief, an instrumentalist account becomes available that delivers (...) the correct epistemic verdicts. On this account, epistemic permissibility can be understood on the model of the wide-scope instrumental norm for instrumental rationality, while normative evidential reasons for belief can be understood in terms of instrumental transmission.

Discussions in contemporary epistemology are burdened with confusions about the terms “rational”, “rationality” and their antonyms. In economy, for an agent to be rational simply means to satisfy the Bayesian probability axioms, but the situation in philosophy is much more complicated. Two kinds of rationality are usually distinguished. Epistemic rationality is an ability to achieve justified and true beliefs, whereas instrumental rationality is a capacity to act in accordance with one’s own interests. This division cleared (...) the way to contemplation about rational irrationality, which is the case when an acceptance of epistemically unwarranted beliefs may increase instrumental profit for an individual. In my article, I will criticize this approach. The proponents of rational irrationality 1) misunderstand the primacy of epistemic rationality over instrumental one; 2) underestimate social nature of normative terms; and 3) misinterpret the evolution of human cognition. I will illustrate my conclusions with an example from applied epistemology – conspiracy theories. It is misleading and disparaging to use the term “rational” in relation to sets of unjustified beliefs that are based on conspiratorial ideation. If philosophers cannot make their ideas on rationality clear, it might be better to leave out rationality completely from the epistemological discourse. (shrink)

The aim of this chapter is to understand more precisely what kind of irrationality involved in procrastination. The chapter argues that in order to understand the irrationality of procrastination one needs to understand the possibility and the nature of what I call “top-down independent” policies and long-term actions. A policy or long-term action) is top-down independent if it is possible to act irrationally relative to the adoption of the policy without ever engaging in a momentary action that is per se (...) irrational. involved in procrastination one needs to It argues that procrastination is one of the corresponding vices of an overlooked virtue; namely, “practical judgment.” On this account, procrastination turns out to be a failure of instrumental rationality that can be so characterized without assuming the correctness of any further norms of practical rationality. Thus this account of procrastination also constitutes an important objection to Christine Korsgaard’s claim that a purely instrumental conception of rationality is incoherent. (shrink)

Do people fall for online disinformation, or do they actively utilize it as a tool to accomplish their goals? Currently, the notion of the members of the public as victims of deception and manipulation prevails in the debate. It emphasizes the need to limit people’s exposure to falsehoods and bolster their deficient reasoning faculties. However, the observed epistemic irrationality can also stem from politically motivated reasoning incentivized by digital platforms. In this context, the readily available disinformation facilitates an arms race (...) in loyalty signaling via a public endorsement of fanciful partisan claims. Such a signaling arms race appears capable of derailing democratic decision-making perhaps more effectively than any known reasoning deficiency. Appreciating the role of an instrumentally rational cost-benefit calculus in triggering the disinformation crisis thus appears vital. Examining these themes, the paper contributes to the current debates in political epistemology and democratic theory. (shrink)

In their seminal work, Dialectics of Enlightenment, Horkheimer and Adorno interpreted capitalism as the irrational monetization of nature. In the present work, I analyze three 21st century concepts, Anthropocene, Capitalocene and Machinocene, in light of Horkheimer and Adorno’s arguments and recent arguments from the philosophy of biology. The analysis reveals a remarkable prescience of the term “instrumental reason”, which is present in each of the three concepts in a profound and cryptic way. In my interpretation, the term describes the (...) propensity of science based on the notion of physicalism to interpret nature as the machine analyzable and programmable by the human reason. As a result, the Anthropocene concept is built around the mechanicist model, which may be presented as the metaphor of the car without brakes. In a similar fashion, the Machinocene concept predicts the emergence of the mechanical mind, which will dominate nature in the near future. Finally, the Capitalocene concept turns a perfectly rational ambition to expand knowledge into an irrational obsession with over-knowledge, by employing the institutionalized science as the engine of capitalism without brakes. The common denominator of all three concepts is the irrational propensity to legitimize self-destruction. Potential avenues for countering the effects of “instrumental reason” are suggested.

Structuralism can be defined as an important concept of using “units” as elements of form and space-giving, where the whole form is made not only up of a “texture”, a certain flexible grid, or an algorithm of shape-giving, but it depends also on the relationships created and how people use it. The hypothesis of this study is that “Modular Construction” can also have an aesthetically pleasing outlook and that modular housing can definitely have increasing importance in the future. Modular housing (...) due to its cheap, and manufactural way of construction can be replicable in various locations. Structuralism and Modular Construction have been at the core of the Modernist movement. Although postmodernism marked the decline of modular construction adopting methods known for a more close sense of place, vernacular, and locality, which differs from the ubiquitous model of modernism, it is the universality of space and habitation seen since the times of Hippodamus Grid, Japanese Tattami systems, and rational universal space in housing known in Europe that make grid and modular design an excellent system in obtaining, rationality, functionality, flexibility, and energy efficiency, including quick construction and possibility for replication. In this regard, modular construction has a future, especially in times of crisis and economic instability. (shrink)

The objective of this article is to demonstrate how the historical debate between materialism and idealism, in the field of Philosophy, extends, in new clothes, to the field of Quantum Physics characterized by realism and anti-realism. For this, we opted for a debate, also historical, between the realism of Albert Einstein, for whom reality exists regardless of the existence of the knowing subject, and Niels Bohr, for whom we do not have access to the ultimate reality of the matter, unless (...) conditioning it to the existence of an observer endowed with rationality, position adopted in the Interpretation of Complementarity – posture that was expanded in 1935 when Bohr assumed a “relationalist” conception, according to which the quantum state is defined by the relationship between the quantum object and the entire measuring device. This is an extremely important debate, as it further consolidates the results of nascent Quantum Mechanics, guaranteeing Bohr the leadership of the orthodoxy based on the interpretation of complementarity. Here, when dealing with Quantum Theory, we will not make any distinction between the terms Quantum Physics, Quantum Theory or Quantum Mechanics. The entire discussion will be held under the name “Quantum Theory”. Theory that tries to analyze and describe the behavior of physical systems of reduced dimensions, close to the sizes of molecules, atoms and subatomic particles. We hope that the reader will appreciate the genius of these two titans in this field of Physics when they magnificently formulate the arguments that support the object of their defenses. (shrink)

This paper critically reviews the arguments supporting rational genuine satisficing. The deconstructive effort unearths inherent problems with the position in both static and dynamic contexts. Many of these arguments build on Herbert Simon’s canonical arguments surrounding incommensurability and demandingness problems. Optimizing is re-constructed using the principles of instrumental satisficing to answer these charges. The resulting conception is both obviously undemanding and a recognizable response to focused decision making.

Epistemic instrumentalism views epistemic norms and epistemic normativity as essentially involving the instrumental relation between means and ends. It construes notions like epistemic normativity, norms, and rationality, as forms of instrumental or means-end normativity, norms, and rationality. I do two main things in this paper. In part 1, I argue that there is an under-appreciated distinction between two independent types of epistemic instrumentalism. These are instrumentalism about epistemic norms and instrumentalism about epistemic normativity. In part 2, (...) I argue that this under-appreciated distinction matters for the debate surrounding the plausibility of EI. Specifically, whether we interpret EI as norm-EI or as source-EI matters for the widely discussed universality or categoricity objection to EI, and for two important motivations for adopting EI, namely naturalism and the practical utility of epistemic norms. I will then conclude by drawing some lessons for epistemic instrumentalism going forward. (shrink)
