According to the Generality Constraint, mental states with conceptual content must be capable of recombining in certain systematic ways. Drawing on empirical evidence from cognitive science, I argue that so-called analogue magnitude states violate this recombinability condition and thus have nonconceptual content. I further argue that this result has two significant consequences: it demonstrates that nonconceptual content seeps beyond perception and infiltrates cognition; and it shows that whether mental states have nonconceptual content is largely an empirical matter determined (...) by the structure of the neural representations underlying them.

We should not admit categorial restrictions on the significance of syntactically well formed strings. Syntactically well formed but semantically absurd strings, such as ‘Life’s but a walking shadow’ and ‘Caesar is a prime number’, can express thoughts; and competent thinkers both are able to grasp these and ought to be able to. Gareth Evans’ generality constraint, though Evans himself restricted it, should be viewed as a fully general constraint on concept possession and propositional thought. For (a) even (...) well formed but semantically cross-categorial strings often do possess substantive inferential roles; (b) hearers exploit these inferential roles in interpreting such strings metaphorically; (c) there is no good reason to deny truth-conditions to strings with inferential roles.

I reply to comments by David Miguel Gray and Grant Gillett concerning my paper, ‘The Generality Constraint and the Structure of Thought’.

Since its introduction by Evans , the generality constraint has been invoked by various philosophers for different purposes. Our purpose here is, first, to clarify what precisely the GC states by way of an interpretive framework, the GC Schema, and second, to demonstrate in terms of this framework some problems that arise if one invokes the GC without clearly specifying an appropriate interpretation. By utilizing the GC Schema these sorts of problems can be avoided, and we thus propose (...) it as a tool to facilitate argumentation that appeals to the GC. (shrink)

I distinguish between being cognisant and being able to perform intelligent operations. The former, but not the latter, minimally involves the capacity to make adequate judgements about one's relation to objects in the environment. The referential nature of cognisance entails that the mental states of cognisant systems must be inter-related holistically, such that an individual thought becomes possible because of its relation to a system of potential thoughts. I use Gareth Evans' 'Generality Constraint' as a means of describing (...) how the reference and holism of mental states in cognisant systems are mutually dependent. Next, I describe attempts to deny the relevance of holism and reference by positing a mentalese. These attempts fail because the meanings of symbols are under determined, with there being no principled means of distinguishing between the mental tokening of a symbol and its disambiguation. I argue that the connectionist meta-theory does not encounter this problem because it is able to encompass the holism of the mental. Recent attempts to show that symbol processing theories of thought must be preferred to connectionist theories do not work. Despite appearances to the contrary, the Generality Constraint favours connectionist not symbol-processing theories. (shrink)

A venerable philosophical tradition claims that only language users possess concepts. But this makes conceptual thought out to be an implausibly rarified achievement. A more recent tradition, based in cognitive science, maintains that any creature who can systematically recombine its representational capacities thereby deploys concepts. But this makes conceptual thought implausibly widespread. I argue for a middle ground: it is sufficient for conceptual thought that one be able to entertain many of the thoughts produced by recombining one’s representational capacities, so (...) long as one can do this apart from a direct confrontation with the represented states of affairs.

All accounts of causality that presuppose the propagation or transfer or some physical stuff to be an essential part of the causal relation rely for the force of their causal claims on a principle of conservation for that stuff. General Relativity does not permit the rigorous formulation of appropriate conservation principles. Consequently, in so far as General Relativity is considered and fundamental physical theory, such accounts of causality cannot be considered fundamental. The continued use of such accounts of causality ought (...) not be proscribed, but justification is due from those who would use them. (shrink)

Generic propositions are statements that make general claims about ‘kinds’ that are found in a wide variety of written genres and speech. By definition, generics do not include in their structure any reference to the conditions under which they hold true. Their misuse in popular scientific writing, however, can erode the public’s confidence in the process of science itself when they discover that conclusions are highly contingent on certain truth conditions. The language used in scholarly scientific papers often includes qualifiers (...) and hedges, the epistemological consequences of which have been explored by Bruno Latour, Thomas Kuhn, Ian Hacking and others. Some research shows that abstracts, however, of-ten include generic statements that are not warranted by the scientific evidence described in the full text. Similarly, when accounts of scientific discoveries appear in popular media, journalists often remove qualifiers, hedges and context markers that existed in the original study. Studies in anthropology by Joseph Dumit, Annemarie Mol, Harris Solomon and others explore the human reactions to such pronouncements. One possible solution to the over-use of generics in scientific abstracts, especially for studies that rely on human subjects, is the inclusion of a mandatory section entitled “Constraints on Generality,” as suggested by Gutiérrez and Rogoff. Other suggestions include using less nominalized verbs and more past-tense descriptions of what actually occurred in the particular study. (shrink)

I argue that general constraints on how humans think about humans produce universal features of the concept of mind. Some of these constraints determine how we imagine other people's thinking and action through our own. I formulate this in opposition to what I call the "theory theory". I believe this was the first use of this terminology, and this work was an early version of what has come to be called the simulation theory.

Two general principles have played a crucial role in the recent debate on concepts. On the one hand, we want to allow different subjects to have the same concepts, thus accounting for concept publicity: concepts are ‘the sort of thing that people can, and do, share’. On the other hand, a subject who finds herself in a so-called ‘Frege case’ appears to have different concepts for the same object: for instance, Lois Lane has two distinct concepts SUPERMAN and CLARK KENT (...) which refer to the same person. Several theories have tried to meet both of these constraints at the same time. But should we really try to satisfy both principles? This paper will argue that the traditional project of fulfilling these two constraints has been a misguided one. Through a variation on classic identity mistake cases, I will show that our two desiderata are inconsistent: it would thus be impossible to incorporate both of them in our best theory of concepts.

Many people hold the constraint against doing harm, the view that the reason against doing harm is stronger than the reason against merely allowing harm, everything else being equal. Mogensen and MacAskill (2021) have recently argued that when considering indirect long-term consequences of our everyday behavior, the constraint against doing harm faces a problem: it has the absurd implication that we should do as little as possible in our lives. In this paper, I explore the view that, for (...) behavior that does not increase anyone’s ex ante risk of suffering harm, the reason against doing harm is not stronger than the reason against merely allowing harm, everything else being equal. I argue that this view is plausible, show how it solves the paralysis problem, and defend it against objections. (shrink)

The paper examines constraints and preferences employed by people in learning decision rules from preclassified examples. Results from four experiments with human subjects were analyzed and compared with artificial intelligence (AI) inductive learning programs. The results showed the people's rule inductions tended to emphasize category validity (probability of some property, given a category) more than cue validity (probability that an entity is a member of a category given that it has some property) to a greater extent than did the AI (...) programs. Although the relative proportions of different rule types (e.g., conjunctive vs. disjunctive) changed across experiments, a single process model provided a good account of the data from each study. These observations are used to argue for describing constraints in terms of processes embodied in models rather than in terms of products or outputs. Thus AI induction programs become candidate psychological process models and results from inductive learning experiments can suggest new algorithms. More generally, the results show that human inductive generalizations tend toward greater specificity than would be expected if conceptual simplicity were the key constraint on inductions. This bias toward specificity may be due to the fact that this criterion both maximizes inferences that may be drawn from category membership and protects rule induction systems from developing over‐generalizations.

Life scientists increasingly rely upon abstraction-based modeling and reasoning strategies for understanding biological phenomena. We introduce the notion of constraint-based reasoning as a fruitful tool for conceptualizing some of these developments. One important role of mathematical abstractions is to impose formal constraints on a search space for possible hypotheses and thereby guide the search for plausible causal models. Formal constraints are, however, not only tools for biological explanations but can be explanatory by virtue of clarifying general dependency-relations and patterning (...) between functions and structures. We describe such situations as constraint-based explanations and argue that these differ from mechanistic strategies in important respects. While mechanistic explanations emphasize change-relating causal features, constraint-based explanations emphasize formal dependencies and generic organizational features that are relatively independent of lower-level changes in causal details. Our distinction between mechanistic and constraint-based explanations is pragmatically motivated by the wish to understand scientific practice. We contend that delineating the affordances and assumptions of different explanatory questions and strategies helps to clarify tensions between diverging scientific practices and the innovative potentials in their combination. Moreover, we show how constraint-based explanation integrates several features shared by otherwise different philosophical accounts of abstract explanatory strategies in biology. (shrink)

Simulation constraints cannot help in explaining afterlife beliefs in general because belief in an afterlife is a precondition for running a simulation. Instead, an explanation may be found by examining more deeply our common-sense dualistic conception of the mind or soul.

There exist many competing philosophical definitions of joint action and no clear criteria to decide between them; so far the search for definitions has by and large been a semantical enterprise rather than an empirical one. This chapter describes and assesses several constraints that could help converge towards a set of necessary and sufficient conditions for joint action. The tightness constraint favours definitions that fit joint actions in which the links between agents are as relaxed as possible, so as (...) to better pinpoint the conceptual core of jointness. The developmental constraint asks for definitions based on realistic psychological states that could be entertained by agents less cognitively developed than ideal human beings. The motor constraint holds that definitions should refer to psychological mechanisms involved in actual human coordination. These first three constraints are discussed and dismissed, mainly because they manage to establish vague limits at best (for various reasons). I then introduce a fourth one, the efficiency constraint, based on the fact that most of our joint actions are generally successful, and according to which definitions should involve conditions that help justify this success. Finally, the rational and evolutionary versions of the efficiency constraint are examined and defended against objections. (shrink)

In a previous paper we developed a general theory of input/output logics. These are operations resembling inference, but where inputs need not be included among outputs, and outputs need not be reusable as inputs. In the present paper we study what happens when they are constrained to render output consistent with input. This is of interest for deontic logic, where it provides a manner of handling contrary-to-duty obligations. Our procedure is to constrain the set of generators of the input/output system, (...) considering only the maximal subsets that do not yield output conflicting with a given input. When inputs are authorised to reappear as outputs, both maxichoice revision in the sense of Alchourr6n/Makinson and the default logic of Poole emerge as special cases, and there is a close relation with Reiter default logic. However, our focus is on the general case where inputs need not be outputs. We show in what contexts the consistency of input with output may be reduced to its consistency with a truth-functional combination of components of generators, and under what conditions constrained output may be obtained by a derivation that is constrained at every step.

According to best systems accounts, laws of nature are generalizations in the best systematization of particular matters of fact. Metrics such as simplicity and strength determine which systematization is best, but these are notoriously language relative. For this reason, David Lewis proposed a constraint on languages of inquiry: all predicates must be natural. This constraint is sometimes interpreted as requiring us to know which natural properties are instantiated in our world prior to scientific theorizing. I argue that this (...) interpretation is incorrect. I provide a better interpretation and show how it undercuts an influential epistemological objection to Lewis's best systems account of laws due to Bas van Fraassen. (shrink)

This essay considers arguments for and against syntactical constraints on the proper formalization of definitions, originally owing to Alfred Tarski. It discusses and refutes an application of the constraints generalized to include a prohibition against not only object-place but also predicate-place variables in higher-order logic in a criticism of a recent effort to define the concept of heterologicality in a strengthened derivation of Grelling's paradox within type theory requirements. If the objections were correct, they would offer a more general moral (...) for the proper formal definition of terms in philosophical logic. The criticism nevertheless seems mistaken both in the substance and specific application with respect to legitimate synctactical constraints on definitions of key concepts in the case of Grelling's paradox. As such, the critique provides no justification for overturning previous conclusions concerning the possibility of resurrecting a type-observant version of Grelling's heterologicality paradox.

In this paper, we first review recent arguments about the direct perception of the intentions and emotions of others, emphasizing the role of embodied interaction. We then consider a possible objection to the direct perception hypothesis from social psychology, related to phenomena like ‘dehumanization’ and ‘implicit racial bias’, which manifest themselves on a basic bodily level. On the background of such data, one might object that social perception cannot be direct since it depends on and can in fact be interrupted (...) by a set of cultural beliefs. We argue, however, that far from threatening the idea of direct perception, these findings clearly contradict the idea of hardwired theory of mind modules. More generally, we suggest that in order to further the understanding of social cognition we must take seriously insights about in-group and out-group distinctions and related phenomena, all of which are currently neglected in the mainstream social cognition literature.

The world’s diverse written numeral systems are affected by human cognition; in turn, written numeral systems affect mathematical cognition in social environments. The present study investigates the constraints on graphic numerical notation, treating it neither as a byproduct of lexical numeration, nor a mere adjunct to writing, but as a specific written modality with its own cognitive properties. Constraints do not refute the notion of infinite cultural variability; rather, they recognize the infinity of variability within defined limits, thus transcending the (...) universalist/particularist dichotomy. In place of strictly innatist perspectives on mathematical cognition, a model is proposed that invokes domain-specific and notationally-specific constraints to explain patterns in numerical notations. The analysis of exceptions to cross-cultural generalizations makes the study of near-universals highly productive theoretically. The cross-cultural study of patterns in written numbers thus provides a rich complement to the cognitive analysis of writing systems. (shrink)

Roughly, when an agent performs an action under liberating constraints, the agent could not avoid perfonning that action, her inability to do otherwise stems from her not being able to will to do otherwise, yet in perfonning the action, the agent may well regard herself as having acted freely or autonomously, or “in character” (as opposed to “out of character”), or in conformity with her “deep self.” As action under liberating constraints issues from one’s “deep self,” it seems reasonable to (...) suppose, as some have recommended, that whenever a person acts under such constraints, she is morally responsible for her action.

This paper describes a theory that explains both the creativity and the efficiency of people's conceptual combination. In the constraint theory, conceptual combination is controlled by three constraints of diagnosticity, plausibility, and informativeness. The constraints derive from the pragmatics of communication as applied to compound phrases. The creativity of combination arises because the constraints can be satisfied in many different ways. The constraint theory yields an algorithmic model of the efficiency of combination. The C3 model admits the full (...) creativity of combination and yet efficiently settles on the best interpretation for a given phrase. The constraint theory explains many empirical regularities in conceptual combination, and makes various empirically verified predictions. In computer simulations of compound phrase interpretation, the C3 model has produced results in general agreement with people's responses to the same phrases. (shrink)

CULTURE MAY BE metaphorically identified as the space proper to persons, artworks, language, history, institutions, civilizations, states, ideologies, myths, and deeds. In saying that, one signifies that the phenomena of these remarkably varied sorts have much in common that distinguishes them from merely physical or natural phenomena. They have in common whatever demarcates the cultural, and they obtain only in contexts formed by related phenomena. Artworks for example are produced by persons; persons are whatever they are, not without some aggregative (...) sharing of language; and the histories of states are projections of some kind that depend on the deeds of ideologically linked individuals. These are the commonplaces of what is common to the phenomena of culture. They are not as such systematically instructive; for although they collect what is relevant, their explicitness does not touch as yet on the principle of cultural space itself. Nevertheless, the indirection is an economy. It permits us to sort, in a naive way, certain salient clues about the testing of any would-be analysis of the cultural, that might easily be lost otherwise in its own complexities. (shrink)

Visual space can be distinguished from physical space. The first is found in visual experience, while the second is defined independently of perception. Theorists have wondered about the relation between the two. Some investigators have concluded that visual space is non-Euclidean, and that it does not have a single metric structure. Here it is argued that visual space exhibits contraction in all three dimensions with increasing distance from the observer, that experienced features of this contraction are not the same as (...) would be the experience of a perspective projection onto a fronto-parallel plane, and that such contraction is consistent with size constancy. These properties of visual space are different from those that would be predicted if spatial perception resulted from the successful solution of the inverse problem. They are consistent with the notion that optical constraints have been internalized. More generally, they are also consistent with the notion that visual spatial structures bear a resemblance relation to physical spatial structures. This notion supports a type of representational relation that is distinct from mere causal correspondence. The reticence of some philosophers and psychologists to discuss the structure of phenomenal space is diagnosed in terms of the simple materialism and the functionalism of the 1970s and 1980s.

It is claimed that unacceptable constraints on initial data are imposed by certain responses to paradoxes that threaten time travel, closed timelike curves (CTCs) and other backwards causation hypotheses. In this paper I argue against the following claims: to say “contradictions are impossible so something must prevent the paradox” commits in general to constraints on initial data, that for fixed point dynamics so-called grey state solutions explain why contradictions do not arise, and the latter have been proved to avoid constraints (...) on initial data. †To contact the author, please write to: Philosophy, University of Queensland, Brisbane, Queensland 4072, Australia; e-mail: [email protected].

I develop a variant of the constraint interpretation of the emergence of purely physical (non-biological) entities, focusing on the principle of the non-derivability of actual physical states from possible physical states (physical laws) alone. While this is a necessary condition for any account of emergence, it is not sufficient, for it becomes trivial if not extended to types of constraint that specifically constitute physical entities, namely, those that individuate and differentiate them. Because physical organizations with these features are (...) in fact interdependent sets of such constraints, and because such constraints on physical laws cannot themselves be derived from physical laws, physical organization is emergent. These two complementary types of constraint are components of a complete non-reductive physicalism, comprising a non-reductive materialism and a non-reductive formalism. (shrink)

The general purposes of this essay are as follows: First, to outline an ecological model of autobiographical remembering by examining the purposes, processes, and products of reconstructing meaningful memories. Second, to argue that autobiographical remembering is embedded in affective, interpersonal, sociocultural, and historical contexts. Improvised selves are created in present contexts to serve psychosocial, cultural, and historical purposes, and third, to demonstrate essential constraints on the construction of coherent personal narratives that give meaning and purpose to our everyday lives. -/- (...) The specific aim of this essay is to illustrate that the subjective experiences of trauma and atrocity often lack the essential narrative elements needed to give coherence to those experiences as well as affectively grounded evaluative information. Evaluations of experiences give meaning to our lives. Evaluative information leads to culturally recognized coherent stories structured by known canonical narrative forms because affect conveys how subjective experiences should be interpreted and understood. On this view, autobiographical memories that are the essence of one's personal history can appear as coherent or incoherent to others to the extent others are familiar with the narrative structure used to reconstruct the past and the coherence inherent in autobiographical memories associated with the temporal and evaluative structure of those recollections. -/- I claim that autobiographical experiences that cannot be reconstructed and shared through spoken or written language, music, movement (e.g., dance), art, literature, or science precipitate feelings of existential stress because articulated deep motivations cannot be related intimately to others.

Understanding the role mechanistic constraints play in shaping evolution can relieve the tension between the generally accepted intuition that there are no strict laws in biology and empirical findings showing that evolutionary processes are biased toward preferred outcomes. Mechanistic constraints explain why some evolutionary outcomes are more probable than others and allow for predictions in specific lineages. At the same time, mechanistic constraints are neither necessary nor universal in the way laws are traditionally characterized: they remain contingent on the past (...) evolution of the biological mechanisms underpinning them and only constrain the future evolution of the organisms possessing them.

The grammatical constraints on anaphoric binding, known as binding principles, are observed to form a classical square of oppositions. These constraints are then analysed as the effect of phase quantifiers over reference markers in grammatical obliqueness hierarchies, and the resulting phase quantifiers are shown to be organised in a square of logical duality. The impact of this result on the distinction between quantificational and referential nominals as well as on the logical foundations of the semantics of nominals in general is (...) discussed.

This paper provides evidence for a contrastive account of explanation that is motivated by pragmatic theories that recognize the contribution that context makes to the interpretation of a prompt for explanation. This study replicates the primary findings of previous work in explanation-based category learning, extending that work by illustrating the critical role of the context in this type of learning. Participants interacted with items from two categories either by describing the items or explaining their category membership. We manipulated the feature (...) overlap between the categories and examined both the explanations generated and acquired knowledge of the categories. Explanations for membership in a given category were influenced by the unprompted contrast category, indicating an important role for contrastive processing in the generation of explanations. The influence of the contrast category was similarly seen in the transfer performance of the participants. (shrink)
