Surprisal and Valuation in the Predictive Brain.

This chapter elaborates and develops the thesis originally put forward by Mary Morgan (2005) that some mathematical models may surprise us, but that none of them can completely confound us, i.e. let us unable to produce an ex post theoretical understanding of the outcome of the model calculations. This chapter intends to object and demonstrate that what is certainly true of classical mathematical models is however not true of pluri-formalized simulations with multiple axiomatic bases. This chapter thus proposes to (...) show that - and why - some of these computational simulations that are now booming in the sciences not only surprise us but also confound us. To do so, it shows too that it is needed to elaborate and articulate with some new precision the concept of weak emergence initially due, for its part, to Mark A. Bedau (1997). (shrink)

The authors show that some long-standing confusions and problems can be avoided by thinking of perception in terms of sensorimotor contingencies, a close kin to my heterophenomenological approach (Dennett 1991). However, their claim that subjects do not have any commitments about the resolution of their visual fields is belied by the surprise routinely expressed by subjects when this is demonstrated to them.

Surprises are important in our everyday lives as well as in our scientific and philosophical theorizing—in psychology, information theory, cognitive-neuroscience, philosophy of science, and confirmation theory. Nevertheless, there is no satisfactory theory of what makes something surprising. It has long been acknowledged that not everything unexpected is surprising. The reader had no reason to expect that there will be exactly 190 words in this abstract and yet there is nothing surprising about this fact. We offer a novel theory that explains (...) when and why an unexpected fact is surprising. We distinguish between descriptive and normative notions of what is surprising; clarify the sense in which surprising facts are unexpected; and, finally, develop and defend the significance account of surprise, according to which a fact is surprising to an agent if and to the extent that it is both unexpected and significant to the agent. Since a surprising fact can be significant to an agent in various ways—personal, moral, epistemic, and aesthetic—surprise is not merely or primarily epistemic. Fitting surprise reflects more than a person’s view of what is; it reflects a person’s view of what is significant. (shrink)

Knowledge is good, ignorance is bad. So it seems, anyway. But in this dissertation, I argue that some ignorance is epistemically valuable. Sometimes, we should suspend judgment even though by believing we would achieve knowledge. In this apology for ignorance (ignorance, that is, of a certain kind), I defend the following four theses: 1) Sometimes, we should continue inquiry in ignorance, even though we are in a position to know the answer, in order to achieve more than mere knowledge (e.g. (...) understanding) while minimizing the effects of confirmation bias. 2) It’s false that we should believe every proposition such that we are guaranteed to be right about it (and even such that we are guaranteed to know it) if we believe it. 3) Being in a position to know is the norm of assertion: importantly, this does not require belief or (thereby) knowledge, and so proper assertion can survive speaker-ignorance. 4) It can be permissible and conversationally useful to tell audiences things that it is logically impossible for them to come to know: Proper assertion can survive (necessary) audience-side ignorance. Cumulatively, this project suggests that, properly understood, ignorance has an important role to play in the good epistemic life. (shrink)

A number of researchers have begun to demonstrate that the widely discussed ?Knobe effect? (wherein participants are more likely to think that actions with bad side-effects are brought about intentionally than actions with good or neutral side-effects) can be found in theory of mind judgments that do not involve the concept of intentional action. In this article we report experimental results that show that attributions of knowledge can be influenced by the kinds of (non-epistemic) concerns that drive the Knobe effect. (...) Our findings suggest there is good reason to think that the epistemic version of the Knobe effect is a theoretically significant and robust effect, and that the goodness or badness of side-effects can often have greater influence on participant knowledge attributions than explicit information about objective probabilities. Thus, our work sheds light on important ways in which participant assessments of actions can affect the epistemic assessments participants make of agents? beliefs. (shrink)

JOHN CORCORAN AND WILIAM FRANK. Surprises in logic. Bulletin of Symbolic Logic. 19 253. Some people, not just beginning students, are at first surprised to learn that the proposition “If zero is odd, then zero is not odd” is not self-contradictory. Some people are surprised to find out that there are logically equivalent false universal propositions that have no counterexamples in common, i. e., that no counterexample for one is a counterexample for the other. Some people would be surprised to (...) find out that in normal first-order logic existential import is quite common: some universals “Everything that is S is P” —actually quite a few—imply their corresponding existentials “Something that is S is P”. Anyway, perhaps contrary to its title, this paper is not a cataloging of surprises in logic but rather about the mistakes that did or might have or might still lead people to think that there are no surprises in logic. The paper cataloging of surprises in logic is on our “to-do” list. -/- ► JOHN CORCORAN AND WILIAM FRANK, Surprises in logic. Philosophy, University at Buffalo, Buffalo, NY 14260-4150, USA E-mail: [email protected] There are many surprises in logic. Peirce gave us a few. Russell gave Frege one. Löwenheim gave Zermelo one. Gödel gave some to Hilbert. Tarski gave us several. When we get a surprise, we are often delighted, puzzled, or skeptical. Sometimes we feel or say “Nice!”, “Wow, I didn’t know that!”, “Is that so?”, or the like. Every surprise belongs to someone. There are no disembodied surprises. Saying there are surprises in logic means that logicians experience surprises doing logic—not that among logical propositions some are intrinsically or objectively “surprising”. The expression “That isn’t surprising” often denigrates logical results. Logicians often aim for surprises. In fact, [1] argues that logic’s potential for surprises helps motivate its study and, indeed, helps justify logic’s existence as a discipline. Besides big surprises that change logicians’ perspectives, the logician’s daily life brings little surprises, e.g. that Gödel’s induction axiom alone implies Robinson’s axiom. Sometimes wild guesses succeed. Sometimes promising ideas fail. Perhaps one of the least surprising things about logic is that it is full of surprises. Against the above is Wittgenstein’s surprising conclusion : “Hence there can never be surprises in logic”. This paper unearths basic mistakes in [2] that might help to explain how Wittgenstein arrived at his false conclusion and why he never caught it. The mistakes include: unawareness that surprise is personal, confusing logicians having certainty with propositions having logical necessity, confusing definitions with criteria, and thinking that facts demonstrate truths. People demonstrate truths using their deductive know-how and their knowledge of facts: facts per se are epistemically inert. [1] JOHN CORCORAN, Hidden consequence and hidden independence.

Despite having been solved numerous times, the surprise quiz paradox persists in the intellectual imagination as a riddle. This dialogue aims to dispel the fallacies of the paradox in an intuitive way through the causal format of a dialogue. Along the way, two contributions are made to the literature. Even if the student knew there would be a quiz at the end of a quizless Thursday, the fact that the quiz will be a surprise Friday would provide a (...) Gettier-style defeater for his supposed knowledge that he will have a quiz Friday. In addition, pace Sorensen (1988), the dialogue explains why the temporal retention of knowledge is essential to the puzzle and not a mere accident. (shrink)

Simulation modeling, the core thesis of Calculated Surprises, is transforming the established conception of mathematical modeling in fundamental ways. These transformations feed back into philosophy of science, opening up new perspectives on longstanding oppositions. The book integrates historical features with both practical case studies and broad reflections on science and technology.

Mirativity is a grammatical category or a linguistic strategy that makes explicit the surprising aspect of a piece of information. Different mirativity strategies appear in different languages. Evidentiality is a grammatical category that explicitly expresses the source of information, i.e. if something has been seen, heard or inferred. Whether mirativity forms part of evidentiality is an open question. An agent makes use of a mirativity marker when she or he expresses something about a surprising fact with respect to her or (...) his background knowledge. But there are different kinds of mirativity markers. Some of them are simple and direct and others, more complex, involve inferential processes. Here, we focus on complex mirativity and we compare it with inferred evidentials and deferred realizations. Our proposal goes beyond the purely linguistic analysis, since we try to interpret mirativity, and its role in interaction, as forming part of or involving a particular kind of inference, namely abduction. Mirativity can be used to express the surprising state that triggers an abductive reasoning but it can also encapsulate its result in such a way that it can be understood in relation to evidentiality. Thus, at least in some cases of complex mirativity, mirativity may convey indication about the source of information. Interesting for studies on dialogue is that they also indicate the degree of commitment of the speakers with the content of their own utterances. (shrink)

The judgment that a given event is epistemically improbable is necessary but insufficient for us to conclude that the event is surprising. Paul Horwich has argued that surprising events are, in addition, more probable given alternative background assumptions that are not themselves extremely improbable. I argue that Horwich’s definition fails to capture important features of surprises and offer an alternative definition that accords better with intuition. An important application of Horwich’s analysis has arisen in discussions of fine-tuning arguments. In the (...) second part of the paper I consider the implications for this argument of employing my definition of surprise. I argue that advocates of fine-tuning arguments are not justified in attaching significance to the fact that we are surprised by examples of fine-tuning. (shrink)

To understand the dynamics of the verbalization of surprise, I will start with the philosophical theoretical place that is, in my opinion, the most remarkable in terms of the descriptive phenomenology of surprise, namely, its approach by Paul Ricœur in Freedom and Nature in terms of what he calls “emotion-surprise.” This theoretical position will lead me to retrace, in a second step, the archeology of what Ricoeur calls the “circular phenomenon” or the “circular process” of surprise, (...) which includes body language in a burst of "shaking" and the language of cognitive as well as aesthetic "shock". There is an a priori antinomy here that is based on a post-Cartesian duality of the body and the mind, but it is circularized by Ricoeur. On the basis of this dual model of surprise, I will retrace its genealogy in a number of authors and will analyze some first-person descriptions that come from “microphenomenological interviews” [ entretiens d’explicitation ].

A repackaged edition of the revered author’s spiritual memoir, in which he recounts the story of his divine journey and eventual conversion to Christianity. C. S. Lewis—the great British writer, scholar, lay theologian, broadcaster, Christian apologist, and bestselling author of Mere Christianity, The Screwtape Letters, The Great Divorce, The Chronicles of Narnia, and many other beloved classics—takes readers on a spiritual journey through his early life and eventual embrace of the Christian faith. Lewis begins with his childhood in Belfast, surveys (...) his boarding school years and his youthful atheism in England, reflects on his experience in World War I, and ends at Oxford, where he became "the most dejected and reluctant convert in all England." As he recounts his lifelong search for joy, Lewis demonstrates its role in guiding him to find God. (shrink)

While having a breast reconstruction, women have certain expectations about their future breasted bodies. The aim of this paper is to describe and analyze these expectations in the process of reconstruction. By applying a qualitative, phenomenological study within a longitudinal research design, this paper acknowledges the temporarily complex, contextualized, embodied, and subjective nature of the phenomenon of expectations. The analysis identified expectations regarding three different aspects of women’s embodiment: their gazed body, their capable/practical body, and their felt body. After reconstruction, (...) these women try to reconfigure—adjust, level or retrospectively rewrite—their expectations. Further, some women face what apparently arrives totally unexpected, namely a strange feeling breast or a failed reconstruction. The development of these women’s expectations can be understood as an active, continuously evolving, difficult and sometimes impossible dynamic of expecting the surprise that is a breast reconstruction. Within this dynamic, women formulate and reconfigure—by definition—unrealistic expectations and validate and try to achieve unexpected futures. We suggest that medical professionals can facilitate this dynamic in various ways. (shrink)

The Surprise Exam Paradox is well-known: a teacher announces that there will be a surprise exam the following week; the students argue by an intuitively sound reasoning that this is impossible; and yet they can be surprised by the teacher. We suggest that a solution can be found scattered in the literature, in part anticipated by Wright and Sudbury, informally developed by Sorensen, and more recently discussed, and dismissed, by Williamson. In a nutshell, the solution consists in realising (...) that the teacher's announcement is a blindspot that can only be known if the week is at least 2 days long. Along the way, we criticise Williamson's own treatment of the paradox. In Williamson's view, the Surprise is similar to the Paradox of the Glimpse and, because of their similarities, both these paradoxes ought to receive a uniform treatment-one that involves locating an illicit application of the KK Principle. We argue that there's no deep analogy between the Surprise and the Glimpse and that, even if there were, the Surprise reasoning reaches a paradoxical conclusion before the KK Principle is used. Rather, in both the Surprise and the Glimpse, the blame should be put on other epistemic principles-respectively, a knowledge retention and a margin for error principle. (shrink)

Conciliationism—the thesis that when epistemic peers discover that they disagree about a proposition, both should reduce their confidence—faces a major objection: it seems to require us to significantly reduce our confidence in our central moral and political commitments. In this paper, I develop a typology of disagreement cases and a diagnosis of the source and force of the pressure to conciliate. Building on Vavova’s work, I argue that ordinary and extreme disagreements are surprising, and for this reason, they carry information (...) about the likelihood of error. But deep disagreement is not surprising at all, and token deep disagreements do not put pressure on us to conciliate. However, a pattern of deep disagreements points to a different concern: not the problem of disagreement but the problem of irrelevant influences. Deep disagreement constitutes some pressure to examine the foundations from which we reason, rather than to conciliate on our central moral and political claims. (shrink)

Surprising people can provide an opening for influencing them. Surprises garner attention, are arousing, are memorable, and can prompt shifts in understanding. Less noted is that, as a result, surprises can serve to persuade others by leading them to shifts in attitudes. Furthermore, because stories, pictures, and music can generate surprises and those can be widely shared, surprise can have broad social influence. People also tend to share surprising items with others, as anyone on social media has discovered. This (...) means that in addition to broadcasting surprising information, surprising items can also spread through networks. The joint result is that surprise not only has individual effects on beliefs and attitudes but also collective effects on the content of culture. Items that generate surprise need not be random or accidental. There are predictable methods or recipes for generating surprise. One such recipe is discussed, the repetition-break plot structure, to explore the psychological and social possibilities of examining surprise. Recipes for surprise offer a useful means for understanding how surprise works and offer prospects for harnessing surprise to a wide array of ends. (shrink)

This paper starts by looking at the coincidence of surprising behavior on the nanolevel in both matter and simulation. It uses this coincidence to argue that the simulation approach opens up a pragmatic mode of understanding oriented toward design rules and based on a new instrumental access to complex models. Calculations, and their variation by means of explorative numerical experimentation and visualization, can give a feeling for a model's behavior and the ability to control phenomena, even if the model itself (...) remains epistemically opaque. Thus, the investigation of simulation in nanoscience provides a good example of how science is adapting to a new instrument: computer simulation. (shrink)

Some theorists are bewildered by the effectiveness of mathematical concepts. For example, Steiner attempts to show that there can be no rational explanation of mathematical applicability in physics. Others (notably Penrose) are concerned primarily with the unexpected effectiveness within mathematics. Both views consist of two parts: a puzzle and a positive solution. I defend their paradoxical parts against the sceptics who do not believe that the very problem of effectiveness is a genuine one. Utilising Horwich’s theory of surprise, I (...) argue that the central cases of effectiveness discussed by Steiner and Penrose are indeed surprising and call for an explanation. (shrink)

Surprise is treated as an affect in Aristotelian philosophy as well as in Cartesian philosophy. In experimental psychology, surprise is considered to be an emotion. In phenomenology, it is only addressed indirectly (Husserl, Heidegger, Levinas), with the important exception of Ricoeur and Maldiney; it is reduced to a break in cognition by cognitivists (Dennett). Only recently was it broached in linguistics, with a focus on lexico-syntactic categories. As for the expression of surprise, it has been studied in (...) connection with evidentiality in languages that encode surprise morphosyntactically. However, how surprise is encoded in languages that lack an evidential morphosyntactic system has been largely unexplored. This book provides new insights into the dynamics of surprise based on a heuristic hypothesis tested against the investigation of time, language and emotion. It is intended to arouse the interest of a multidisciplinary audience keen on crossing the disciplinary borders of phenomenology, cognitive sciences, and pragmatics. The theoretical approaches adopted in this collection of articles rely on experiments and corpus data. They advance knowledge by building on robust empirical results coming from psychology, microphenomenology, linguistics and physiology. (shrink)

The experience of musical surprise is explained by psychologists in terms of the thwarting of prior musical expectations. The assumption that surprise is always caused by expectations is widespread not just in psychology at large, but also in philosophy. I argue here that this assumption is ill-founded. Many musical surprises, as well as many non-musical instances of perceptual surprise, can be explained by the falsification of assessments of the present, rendering the appeal to expectations unnecessary. I elaborate (...) the positive view before considering objections, and offering replies. (shrink)

Some formulations of the surprise paradox involve a pair of unnecessary and controversial assumptions. After casting doubt on these assumptions, I propose a solution to the paradox.

Scientific results are often presented as ‘surprising’ as if that is a good thing. Is it? And if so, why? What is the value of surprise in science? Discussions of surprise in science have been limited, but surprise has been used as a way of defending the epistemic privilege of experiments over simulations. The argument is that while experiments can ‘confound’, simulations can merely surprise (Morgan, 2005). Our aim in this paper is to show that the (...) discussion of surprise can be usefully extended to thought experiments and theoretical derivations. We argue that in focusing on these features of scientific practice, we can see that the surprise-confoundment distinction does not fully capture surprise in science. We set out how thought experiments and theoretical derivations can bring about surprises that can be disruptive in a productive way, and we end by exploring how this links with their future fertility.

We examine the paradox of the surprise examination using dynamic epistemic logic. This logic contains means of expressing epistemic facts as well as the effects of learning new facts, and is therefore a natural framework for representing the puzzle. We discuss a number of different interpretations of the puzzle in this context, and show how the failure of principle of success, that states that sentences, when learned, remain to be true and come to be believed, plays a central role (...) in understanding the puzzle.

N-Reasons is an experimental Internet survey platform designed to enhance public participation in applied ethics and policy. N-Reasons encourages individuals to generate reasons to support their judgments, and groups to converge on a common set of reasons pro and con various issues. In the Robot Ethics Survey some of the reasons contributed surprising judgments about autonomous machines. Presented with a version of the trolley problem with an autonomous train as the agent, participants gave unexpected answers, revealing high expectations for the (...) autonomous machine and shifting blame from the automated device to the humans in the scenario. Further experiments with a standard pair of human-only trolley problems refine these results. While showing the high expectations even when no autonomous machine is involved, human bystanders are only blamed in the machine case. A third experiment explicitly aimed at responsibility for driverless cars confirms our findings about shifting blame in the case of autonomous machine agents. We conclude methodologically that both results point to the power of an experimental survey based approach to public participation to explore surprising assumptions and judgments in applied ethics. However, both results also support using caution when interpreting survey results in ethics, demonstrating the importance of qualitative data to provide further context for evaluating judgments revealed by surveys. On the ethics side, the result about shifting blame to humans interacting with autonomous machines suggests caution about the unintended consequences of intuitive principles requiring human responsibility.

Event segmentation theory posits that people segment continuous experience into discrete events and that event boundaries occur when there are large transient increases in prediction error. Here, we set out to test this theory in the context of story listening, by using a deep learning language model (GPT‐2) to compute the predicted probability distribution of the next word, at each point in the story. For three stories, we used the probability distributions generated by GPT‐2 to compute the time series of (...) prediction error. We also asked participants to listen to these stories while marking event boundaries. We used regression models to relate the GPT‐2 measures to the human segmentation data. We found that event boundaries are associated with transient increases in Bayesian surprise but not with a simpler measure of prediction error (surprisal) that tracks, for each word in the story, how strongly that word was predicted at the previous time point. These results support the hypothesis that prediction error serves as a control mechanism governing event segmentation and point to important differences between operational definitions of prediction error.

This volume offers perspectives on the theme of surprise crossing philosophical, phenomenological, scientific, psycho-physiology, psychiatric, and linguistic boundaries. The main question it examines is whether surprise is an emotion. It uses two main theoretical frameworks to do so: psychology, in which surprise is commonly considered a primary emotion, and philosophy, in which surprise is related to passions as opposed to reason. The book explores whether these views on surprise are satisfying or sufficient. It looks at (...) the extent to which surprise is also a cognitive phenomenon and primitively embedded in language, and the way in which surprise is connected to personhood, the interpersonal, and moral emotions. Many philosophers of different traditions, a number of experimental studies conducted over the last decades, recent works in linguistics, and ancestral wisdom testimonies refer to surprise as a crucial experience of both rupture and openness in bodily and inner life. However, surprise is a theme that has not been dealt with directly and systematically in philosophy, in the sciences, in linguistics, or in spiritual traditions. This volume accomplishes just that.

Despite the applicability of assemblage theory to extreme events, the relational ontology that assemblage thinkers employ makes it hard to ground the potential of artefacts to undergo substantial change. To better understand how artefacts can be unexpectedly destroyed, and thereby catch managers by surprise, this article draws on Graham Harman’s object-oriented ontology. This approach is used to explain how artefacts, as concrete objects, have the capacity both to cause and to exacerbate calamities. By contrast, assemblage theory is shown to (...) provide insight into post-disaster organizing dilemmas. An analysis of artefact-based surprise at a disaster-prone New Zealand port illustrates the complementarity of the two approaches. Minimizing surprise was a major impetus behind attempts by port managers to make sizeable artefacts more disaster resilient. Yet there are limits to this process that stem from a gap revealed by the philosophical distinction between an artefact’s design plan and its maximum plan. Object-based surprise at the port also sparked tension between the competing imperatives of centralization and decentralization in post-disaster recovery. How this problem played out at the grassroots level is best explained, however, in assemblage-theoretic terms. (shrink)

The surprise exam paradox is an apparently sound argument to the apparently absurd conclusion that a surprise exam cannot be given within a finite exam period. A closer look at the logic of the paradox shows the argument breaking down immediately. So why do the beginning stages of the argument appear sound in the first place? This paper presents an account of the paradox on which its allure is rooted in a common probabilistic mistake: the base rate fallacy. (...) The account predicts that the paradoxical argument should get less and less convincing as it goes along—a prediction I take to be welcome. On a bleaker note, the account suggests that the base rate fallacy may be more widespread than previously thought. (shrink)

A common intuition about evidence is that if data x have been used to construct a hypothesis H, then x should not be used again in support of H. It is no surprise that x fits H, if H was deliberately constructed to accord with x. The question of when and why we should avoid such “double-counting” continues to be debated in philosophy and statistics. It arises as a prohibition against data mining, hunting for significance, tuning on the signal, (...) and ad hoc hypotheses, and as a preference for predesignated hypotheses and “surprising” predictions. I have argued that it is the severity or probativeness of the test—or lack of it—that should determine whether a double-use of data is admissible. I examine a number of surprising ambiguities and unexpected facts that continue to bedevil this debate. (shrink)

Given the plethora of weight loss interventions, Devine and Barnhill rightly propose to also investigate unintended consequences. I agree. Some questions need to be raised: unintended consequences is a messy concept. How to distinguish between surprises and pseudo-unintended consequences? How to make sure that such research is not a box-ticking formality? And will results be implemented?

This paper discusses a dilemma that’s arises for a surprising number of ethical views and that's generated by a thesis they share: they all hold that it's a necessary condition for a thing to have an ethical property like rightness or goodness that it be accompanied by the belief that it has that property (see e.g. Kant (on one reading), Dworkin, Kymlicka, Sidgwick, Sumner, Dorsey). If the required belief is read one way, these views make it necessary, for a thing (...) to be right or good, that it be accompanied a false belief about its rightness or goodness. If it’s read another way, it generates an infinite regress. (shrink)

It was a happy surprise when, overcoming partisan divisions and interest‐group lobbying, Congress enacted the No Surprises Act, which bans unfair out‐of‐network “balance billing.” Although this is only a modest legislative victory, key efforts by the health policy community made a real difference in a time of legislative gridlock.

These days it seems like everyone knows that we should do something about climate change, but there also seems to be a lot of inertia to take action. Until relatively recently, a common view was that governments would provide the solutions. The Intergovernmental Panel on Climate Change’s (IPCC) special report “SR15”, released in 2018, established that individuals should also contribute to reducing greenhouse gas emissions in order to meet the mitigation requirements to limit warming to 1.5 C. Publicly, there are (...) plenty of good intentions from both individuals and governments, but there’s not a lot of action on either side. So, what’s going on? (shrink)

Parole coupée, bouche bée, yeux grands ouverts, sourcils levés... Plutôt que langagière, l'expression de la surprise serait d'abord le fait du corps. On se propose dans cet ouvrage d'interroger de manière critique, voire de contrebalancer cette tendance habituelle à ranger l'expérience de la surprise du côté du silence et de l'indicible : au lieu de faire signe vers les éventuelles limites du langage et des différentes langues naturelles, la surprise ne fait-elle pas plutôt ressortir la richesse des (...) ressources du langage et la plasticité du fonctionnement des langues? Comment se dit donc la surprise? Dans quelle mesure son expression varie-t-elle d'une langue à l'autre? Le dire de la surprise est-il en lui-même un agir, à son tour producteur d'effets? Ces interrogations nous ont invités à réfléchir tant au lexique de la surprise qu'aux formes d'expression au moyen desquelles la surprise peut être non seulement exprimée mais aussi décrite, racontée, ou bien encore rationalisée, dans la langue courante, dans la logique comme dans la littérature.

Notre propos sera ici des plus modestes dans la mesure où, adoptant un point de vue psychologique, nous ne chercherons pas à conférer à la surprise une signification « profonde » – à la manière dont Heidegger reconnaît à l’angoisse ou à l’ennui une dimension proprement ontologique.

This paper reports a psychological study of human categorization that looked at the procedures used by expert scientists when dealing with puzzling items. Five professional botanists were asked to specify a category from a set of positive and negative instances. The target category in the study was defined by a feature that was unusual, hence situations of uncertainty and puzzlement were generated. Subjects were asked to think aloud while solving the tasks, and their verbal reports were analyzed. A number of (...) problem solving strategies were identified, and subsequently integrated in a model of knowledge‐guided inductive categorization. Our model proposes that expert knowledge influences the subjects' reasoning in more complex ways than suggested by earlier investigations of scientific reasoning. As in previous studies, domain knowledge influenced our subjects' hypothesis generation and testing; but, additionally, it played a central role when subjects revised their hypotheses. (shrink)

In this article I argue against Schroeder's account of the weight of normative reasons. It is shown that in certain cases an agent may have reasons she cannot know about without them ceasing to be reasons, and also reasons she cannot know about at all. Both possibilities are troubling for Schroeder's view.

This “paper” recalls the events that shaped the first international conference of the International Association for Business and Society.

A Treatise of Human Nature opens with ambitious hopes for the science of man, but Hume eventually launches into a series of skeptical arguments that culminates in a report of radical skeptical despair. This essay is a preliminary exploration of how to interpret this surprising development. I first distinguish two kinds of surprise twist: those that are incompatible with some preceding portion of the work, and those that are not. This suggests two corresponding pictures of Hume. On one picture, (...) he believed the skeptical development to be at odds with something in early Treatise; on the other, he took these two portions of Book 1 to be perfectly compatible. After defending the claim that Hume endorsed both of these portions, I sketch two promising interpretations—a “perspectivist,” incompatibilist interpretation and a “post-skeptical,” compatibilist interpretation—and offer some reasons to favor the latter view.

Recent work in cognitive and computational neuroscience depicts human brains as devices that minimize prediction error signals: signals that encode the difference between actual and expected sensory stimulations. This raises a series of puzzles whose common theme concerns a potential misfit between this bedrock informationtheoretic vision and familiar facts about the attractions of the unexpected. We humans often seem to actively seek out surprising events, deliberately harvesting novel and exciting streams of sensory stimulation. Conversely, we often experience some wellexpected sensations (...) as unpleasant and to-be-avoided. In this paper, I explore several core and variant forms of this puzzle, using them to display multiple interacting elements that together deliver a satisfying solution. That solution requires us to go beyond the discussion of simple information-theoretic imperatives and to recognize the essential role of species-specific prestructuring, epistemic foraging, and cultural practices in shaping the restless, curious, novelty-seeking human mind.
