Sergio Tenenbaum and Diana Raffman contend that ‘vague projects’ motivate radical revisions to orthodox, utility-maximising rational choice theory. Their argument cannot succeed if such projects merely ground instances of the paradox of the sorites, or heap. Tenenbaum and Raffman are not blind to this, and argue that Warren Quinn’s Puzzle of the Self-Torturer does not rest on the sorites. I argue that their argument both fails to generalise to most vague projects, and is ineffective in the case of (...) the Self-Torturer itself. (shrink)

This is a reply to discussions by David Copp, Tamar Schapiro, and Sergio Tenenbaum of Michael E. Bratman, Shared Agency: A Planning Theory of Acting Together.

Replies to Joshua Gert, Paul Hurley, and Sergio Tenenbaum and their criticisms of my book Commonsense Consequentialism.

ABSTRACT These are replies to critical discussions by Chrisoula Andreou, Sergio Tenenbaum, and J. David Velleman of my Planning, Time, and Self-Governance: Essays in Practical Rationality. I explain important differences between my appeal to a grounding role of the end of diachronic self-governance and Velleman’s view that ‘intelligibility is [the] constitutive aim of action.’ And I discuss both Velleman’s Quine-inspired conception of norms of plan rationality and his comments on methodology in the philosophy of action. In response to (...) class='Hi'>Tenenbaum, I explain how appeal to a planning agent’s self-governance over time supports basic planning norms. And I explain why my appeal to the significance of the end of one’s diachronic self-governance need not lead to unacceptable bootstrapping. In response to Andreou, I explain why, on my view of rational willpower, the agent’s general assessment in favor of a general pattern of action, while common and important, need not play a fundamental role in a planning agent’s sticking with their prior resolution in the face of temptation.

In his book Appearances of the Good, Sergio Tenenbaum has offered an impressive new defence of a classical account of practical reason, which marks him as heir to a philosophical tradition going back to Aristotle and Kant or, more recently, to Anscombe and Davidson. This account has come under heavy attack in the past twenty years, and it would be no exaggeration to say that it is now a minority view. This is at least so if one counts the (...) number of living philosophers who deny that strict akratic action is possible. Tenenbaum claims that, minimally, his aim is to show that what he calls after Kant “the scholastic view” still merits a place in the philosophical landscape, and in this respect, it is clear that his enterprise is a success.

Tenenbaum and Griffiths (2001) have proposed that their Bayesian model of generalisation unifies Shepard’s (1987) and Tversky’s (1977) similarity-based explanations of two distinct patterns of generalisation behaviours by reconciling them under a single coherent task analysis. I argue that this proposal needs refinement: instead of unifying the heterogeneous notion of psychological similarity, the Bayesian approach unifies generalisation by rendering the distinct patterns of behaviours informationally relevant. I suggest that generalisation as a Bayesian inference should be seen as a complement (...) to, instead of a replacement of, similarity-based explanations. Furthermore, I show that the unificatory powers of the Bayesian model of generalisation can contribute to the selection of one of these models of psychological similarity. (shrink)

Tenenbaum and Griffiths's article continues three disturbing trends that typify category learning modeling: (1) modelers tend to focus on a single induction task; (2) the drive to create models that are formally elegant has resulted in a gross simplification of the phenomena of interest; (3) related research is generally ignored when doing so is expedient. [Tenenbaum & Griffiths].

Tenenbaum and Griffiths (Behavioral and Brain Sciences 24(4):629–640, 2001) have proposed that their Bayesian model of generalisation unifies Shepard’s (Science 237(4820): 1317–1323, 1987) and Tversky’s (Psychological Review 84(4): 327–352, 1977) similarity-based explanations of two distinct patterns of generalisation behaviours by reconciling them under a single coherent task analysis. I argue that this proposal needs refinement: instead of unifying the heterogeneous notion of psychological similarity, the Bayesian approach unifies generalisation by rendering the distinct patterns of behaviours informationally relevant. I suggest (...) that generalisation as a Bayesian inference should be seen as a complement to, instead of a replacement of, similarity-based explanations. Furthermore, I show that the unificatory powers of the Bayesian model of generalisation can contribute to the selection of one of these models of psychological similarity. (shrink)

While Tenenbaum and Griffiths impressively consolidate and extend Shepard's research in the areas of stimulus representation and generalization, there is a need for complexity measures to be developed to control the flexibility of their “hypothesis space” approach to representation. It may also be possible to extend their concept learning model to consider the fundamental issue of representational adaptation. [Tenenbaum & Griffiths].

Griffiths and Tenenbaum (2006) asked individuals to make predictions about the duration or extent of everyday events (e.g., cake baking times), and reported that predictions were optimal, employing Bayesian inference based on veridical prior distributions. Although the predictions conformed strikingly to statistics of the world, they reflect averages over many individuals. On the conjecture that the accuracy of the group response is chiefly a consequence of aggregating across individuals, we constructed simple, heuristic approximations to the Bayesian model premised on (...) the hypothesis that individuals have access merely to a sample of k instances drawn from the relevant distribution. The accuracy of the group response reported by Griffiths and Tenenbaum could be accounted for by supposing that individuals each utilize only two instances. Moreover, the variability of the group data is more consistent with this small‐sample hypothesis than with the hypothesis that people utilize veridical or nearly veridical representations of the underlying prior distributions. Our analyses lead to a qualitatively different view of how individuals reason from past experience than the view espoused by Griffiths and Tenenbaum. (shrink)

This discussion of Sergio Tenenbaum’s excellent book, Rational Powers in Action, focuses on two noteworthy aspects of the big picture. First, questions are raised about Tenenbaum’s methodology of giving primacy to cases in which the agent has all the requisite background knowledge, including knowledge of a means that will be sufficient for achieving her end, and no significant false beliefs. Second, the implications of Tenenbaum’s views concerning the rational constraints on revising our ends are examined.

Tenenbaum and Griffiths' paper attempts to subsume theories of similarity – including spatial models, featural models, and structure-mapping models – into a framework based on Bayesian generalization. But in so doing it misses significant phenomena of comparison. It would be more fruitful to examine how comparison processes suggest hypotheses than to try to derive similarity from Bayesian reasoning. [Shepard; Tenenbaum & Griffiths].

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.

The great advantage of Tenenbaum and Griffiths's model is that it incorporates both specific and general prior knowledge into category learning. Two phenomena are presented as supporting the detailed assumptions of this model. However, one phenomenon, effects of diversity, does not seem to require these assumptions, and the other phenomenon, effects of sample size, is not representative of most reported results. [Tenenbaum & Griffiths].

Roger Shepard's creativity and scientific contributions have left an indelible mark on Psychology and Cognitive Science. In this tribute, I acknowledge and show how his approach to universal laws helped Oden and me shape and develop our universal law of pattern recognition, as formulated in the Fuzzy Logical Model of Perception (FLMP).

Determining the knowledge that guides human judgments is fundamental to understanding how people reason, make decisions, and form predictions. We use an experimental procedure called ‘‘iterated learning,’’ in which the responses that people give on one trial are used to generate the data they see on the next, to pinpoint the knowledge that informs people's predictions about everyday events (e.g., predicting the total box office gross of a movie from its current take). In particular, we use this method to discriminate (...) between two models of human judgments: a simple Bayesian model (Griffiths & Tenenbaum, 2006) and a recently proposed alternative model that assumes people store only a few instances of each type of event in memory (MinK; Mozer, Pashler, & Homaei, 2008). Although testing these models using standard experimental procedures is difficult due to differences in the number of free parameters and the need to make assumptions about the knowledge of individual learners, we show that the two models make very different predictions about the outcome of iterated learning. The results of an experiment using this methodology provide a rich picture of how much people know about the distributions of everyday quantities, and they are inconsistent with the predictions of the MinK model. The results suggest that accurate predictions about everyday events reflect relatively sophisticated knowledge on the part of individuals. (shrink)

This is a rough draft of a critical notice of Sergio Tenenbaum’s book, Appearances of the Good, for Social Theory and Practice.

RÉSUMÉDes travaux récents par Joseph Raz, Niko Kolodny et Sergio Tenenbaum suggèrent qu'il n'existe aucune contrainte normative propre aux intentions. De telles contraintes seraient un mythe. Selon eux, il est possible d'articuler la rationalité des intentions sans postuler que l'intention est un état mental. Je soutiens que nous pouvons aussi comprendre la nature descriptive des intentions sans postuler que l'intention est un état mental. Tout comme l'idée selon laquelle il y aurait des contraintes normatives propres aux intentions, ce postulat (...) est aussi un mythe. L'intention est plutôt une action accompagnée de certaines sous-actions caractéristiques et jouant un rôle de coordination. (shrink)

The probabilistic analysis of functional questions is maturing into a rigorous and coherent research paradigm that may unify the cognitive sciences, from the study of single neurons in the brain to the study of high level cognitive processes and distributed cognition. Endless debates about undecidable structural issues (modularity vs. interactivity, serial vs. parallel processing, iconic vs. propositional representations, symbolic vs. connectionist models) may be put aside in favor of a rigorous understanding of the problems solved by organisms in their natural (...) environments.

In this paper, we describe a model that learns semantic representations from the distributional statistics of language. This model, however, goes beyond the common bag‐of‐words paradigm, and infers semantic representations by taking into account the inherent sequential nature of linguistic data. The model we describe, which we refer to as a Hidden Markov Topics model, is a natural extension of the current state of the art in Bayesian bag‐of‐words models, that is, the Topics model of Griffiths, Steyvers, and Tenenbaum (...) (2007), preserving its strengths while extending its scope to incorporate more fine‐grained linguistic information. (shrink)

The contents of the inaugural volume of Oxford Studies in Metaethics nicely mirror the variety of issues that make this area of philosophy so interesting. The volume opens with Peter Railton's exploration of some central features of normative guidance, the mental states that underwrite it, and its relationship to our reasons for feeling and acting. In the next offering, Terence Cuneo takes up the case against expressivism, arguing that its central account of the nature of moral judgments is badly mistaken. (...) Terence Horgan and Mark Timmons, two of the most prominent contemporary expressivists, then offer their take on how expressivism manages to avoid a different objection-that of collapsing into an objectionable form of relativism. Daniel Jacobson and Justin D'Arms next offer an article that continues their research program devoted to exploring the extent to which values might depend upon, or be constrained by, human psychology. Ralph Wedgwood engages in some classical metaethical conceptual analysis, seeking to explicate the meaning of ought. Mark van Roojen then contributes a new take on the Moral Twin Earth Argument, a prominent anti-realist puzzle advanced in the early 1990s by Horgan and Timmons. -/- Allan Gibbard next presents his latest thoughts on the nature of moral feelings and moral concepts, crucial elements in the overall project of defending the expressivism he is so well known for. James Dreier then takes up the details of Gibbard's recent efforts to provide a solution to what many view as the most serious difficulty for expressivism, namely, the Frege-Geach problem. Dreier identifies difficulties in Gibbard's expressivist account, and offers a suggestion for their solution. Sergio Tenenbaum explores the concept of a direction of fit, relied on so heavily nowadays in accounts of moral motivation. Nadeem Hussain and Nishiten Shah then consider the merits of Christine Korsgaard's influential critique of moral realism. T. M. Scanlon's widely-discussed buck-passing account of value attracts the critical eye of Pekka Väyrynen, who attempts to reveal the reasons that we might resist it. Derek Parfit's contribution concludes this volume, with an article on normativity that presents his most recent thinking on this fundamental notion. (shrink)

I begin the paper by outlining one classic argument for the guise of the good: that we must think that desires represent their objects favourably in order to explain why they can make actions rational (Quinn 1995; Stampe 1987). But what exactly is the conclusion of this argument? Many have recently formulated the guise of the good as the view that desires are akin to perceptual appearances of the good (Oddie 2005; Stampe 1987; Tenenbaum 2007). But I argue that (...) this view fails to capitalize on the above argument, and that the argument is better understood as favouring a view on which desires are belief-like states. I finish by addressing some countervailing claims made by Avery Archer (2016). (shrink)

An important recent debate in the philosophy of action has focused on whether there is a persistence requirement on intention and, if there is, what its proper formulation should be. At one extreme, Bratman has defended what I call Strong Persistence, according to which it’s irrational to abandon an intention except for an alternative that is better supported by one’s reasons. At the other extreme, Tenenbaum has argued that there isn’t a persistence requirement on intention at all. In the (...) middle, philosophers like Broome, Ferrero, and Paul have defended persistence requirements with varying degrees of stringency while agreeing that Bratman’s proposed requirement is too strong. In this paper I side with Bratman in defending Strong Persistence. I argue, however, that Bratman’s own argument in favor of it is defective and an easy prey to the multiple objections that have been leveled against it. I thus offer in its place a “first-personally addressed constitutivist argument” whose aim is to show to the minimally reflective agent the kind of commitment involved in deciding and forming an intention in situations of incomparability—which are taken to be the litmus test for persistence requirements—and the persistence rational requirement governing it. Along the way I respond to the objections against Strong Persistence and explain why my argument represents an improvement over Bratman’s. (shrink)

We criticise Shepard's notions of “invariance” and “universality,” and the incorporation of Shepard's work on inference into the general framework of his paper. We then criticise Tenenbaum and Griffiths' account of Shepard (1987b), including the attributed likelihood function, and the assumption of “weak sampling.” Finally, we endorse Barlow's suggestion that minimum message length (MML) theory has useful things to say about the Bayesian inference problems discussed by Shepard and Tenenbaum and Griffiths.

The focus of this paper is two-fold. First, similarities generated from six semantic models were compared to human ratings of paragraph similarity on two datasets—23 World Entertainment News Network paragraphs and 50 ABC newswire paragraphs. Contrary to findings on smaller textual units such as word associations (Griffiths, Tenenbaum, & Steyvers, 2007), our results suggest that when single paragraphs are compared, simple nonreductive models (word overlap and vector space) can provide better similarity estimates than more complex models (LSA, Topic Model, (...) SpNMF, and CSM). Second, various methods of corpus creation were explored to facilitate the semantic models’ similarity estimates. Removing numeric and single characters, and also truncating document length improved performance. Automated construction of smaller Wikipedia-based corpora proved to be very effective, even improving upon the performance of corpora that had been chosen for the domain. Model performance was further improved by augmenting corpora with dataset paragraphs. (shrink)

Miller (1956) identified his famous limit of 7 ± 2 items based in part on absolute identification—the ability to identify stimuli that differ on a single physical dimension, such as lines of different length. An important aspect of this limit is its independence from perceptual effects and its application across all stimulus types. Recent research, however, has identified several exceptions. We investigate an explanation for these results that reconciles them with Miller’s work. We find support for the hypothesis that the (...) exceptional stimulus types have more complex psychological representations, which can therefore support better identification. Our investigation uses data sets with thousands of observations for each participant, which allows the application of a new technique for identifying psychological representations: the structural forms algorithm of Kemp and Tenenbaum (2008). This algorithm supports inferences not possible with previous techniques, such as multidimensional scaling. (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)

Children acquire complex concepts like DOG earlier than simple concepts like BROWN, even though our best neuroscientific theories suggest that learning the former is harder than learning the latter and, thus, should take more time (Werning 2010). This is the Complex- First Paradox. We present a novel solution to the Complex-First Paradox. Our solution builds on a generalization of Xu and Tenenbaum’s (2007) Bayesian model of word learning. By focusing on a rational theory of concept learning, we show that (...) it is easier to infer the meaning of complex concepts than that of simple concepts. (shrink)
