Detecting that two images are different is faster for highly dissimilar images than for highly similar images. Paradoxically, we showed that the reverse occurs when people are asked to describe how two images differ—that is, to state a difference between two images. Following structure-mapping theory, we propose that this disassociation arises from the multistage nature of the comparison process. Detecting that two images are different can be done in the initial (local-matching) stage, but only for pairs with low overlap; thus, (...) “different” responses are faster for low-similarity than for high-similarity pairs. In contrast, identifying a specific difference generally requires a full structural alignment of the two images, and this alignment process is faster for high-similarity pairs. We described four experiments that demonstrate this dissociation and show that the results can be simulated using the Structure-Mapping Engine. These results pose a significant challenge for nonstructural accounts of similarity comparison and suggest that structural alignment processes play a significant role in visual comparison. (shrink)

This article looks at the way people determine the antecedent of a pronoun in sentence pairs, such as: Albert invited Ron to dinner. He spent hours cleaning the house. The experiment reported here is motivated by the idea that such judgments depend on reasoning about identity . Because the identity of an individual over time depends on the causal-historical path connecting the stages of the individual, the correct antecedent will also depend on causal connections. The experiment varied how likely it (...) is that the event of the first sentence would cause the event of the second for each of the two individuals . Decisions about the antecedent followed causal likelihood. A mathematical model of causal identity accounted for most of the key aspects of the data from the individual sentence pairs. (shrink)

The alignment of bargaining positions is crucial to a successful negotiation. Prior research has shown that similarity in language use is indicative of the conceptual alignment of interlocutors. We use latent semantic analysis to explore how the similarity of language use between negotiating parties develops over the course of a three-party negotiation. Results show that parties that reach an agreement show a gradual increase in language similarity over the course of the negotiation. Furthermore, reaching the most financially efficient outcome is (...) dependent on similarity in language use between the parties that have the most to gain from such an outcome. (shrink)

Metaphors are cognitive and linguistic tools that allow reasoning. They enable the understanding of abstract domains via elements borrowed from concrete ones. The underlying mechanism in metaphorical mapping is the manipulation of concepts. This article proposes another view on what concepts are and their role in metaphor and reasoning. That is, based on current neuroscientific and behavioural evidence, it is argued that concepts are grounded in perceptual and motor experience with physical and social environments. This definition of concepts is then (...) embedded in the Structure-Mapping Theory, a model for metaphorical processing and reasoning. The blended view of structure-mapping and embodied cognition offers an insight into the processes through which the target domain of a metaphor is embodied or realised in terms of its base domain. The implications of the proposed embodied SMT model are then discussed and future topics of investigation are outlined. (shrink)

We present a new theoretical construct labeled motivational readiness. It is defined as the inclination, whether or not ultimately implemented, to satisfy a desire. A general model of readiness is described which builds on the work of prior theories, including animal learning models and personality approaches, and which aims to integrate a variety of research findings across different domains of motivational research. Components of this model include the Want state, and the Expectancy of being able to satisfy that Want. We (...) maintain that the Want concept is the critical ingredient in motivational readiness: without it, readiness cannot exist. In contrast, some motivational readiness can exist without Expectancy. We also discuss the role of incentive in motivational readiness. Incentive is presently conceived of in terms of a Match between a Want and a Perceived Situational Affordance. Whereas in classic models incentive was portrayed as a first order determinant of motivational readiness, here we describe it as a second order factor which affects readiness by influencing Want, Expectancy, or both. The new model’s relation to its theoretical predecessors, and its implications for future research, also are discussed. (shrink)

Law, Economics, and Morality examines the possibility of combining economic methodology and deontological morality through explicit and direct incorporation of moral constraints into economic models. Economic analysis of law is a powerful analytical methodology. However, as a purely consequentialist approach, which determines the desirability of acts and rules solely by assessing the goodness of their outcomes, standard cost-benefit analysis is normatively objectionable. Moderate deontology prioritizes such values as autonomy, basic liberties, truth-telling, and promise-keeping over the promotion of good outcomes. It (...) holds that there are constraints on promoting the good. Such constraints may be overridden only if enough good is at stake. While moderate deontology conforms to prevailing moral intuitions and legal doctrines, it is arguably lacking in methodological rigor and precision. Eyal Zamir and Barak Medina argue that the normative flaws of economic analysis can be rectified without relinquishing its methodological advantages and that moral constraints can be formalized so as to make their analysis more rigorous. They discuss various substantive and methodological choices involved in modeling deontological constraints. Zamir and Medina propose to determine the permissibility of any act or rule infringing a deontological constraint by means of mathematical threshold functions. Law, Economics, and Morality presents the general structure of threshold functions, analyzes their elements and addresses possible objections to this proposal. It then illustrates the implementation of constrained CBA in several legal fields, including contract law, freedom of speech, antidiscrimination law, the fight against terrorism, and legal paternalism.

We show that there is a restriction, or modification of the finite-variable fragments of First Order Logic in which a weak form of Craig's Interpolation Theorem holds but a strong form of this theorem does not hold. Translating these results into Algebraic Logic we obtain a finitely axiomatizable subvariety of finite dimensional Representable Cylindric Algebras that has the Strong Amalgamation Property but does not have the Superamalgamation Property. This settles a conjecture of Pigozzi [12].

We revisit the analogy suggested by Madelung between a non-relativistic time-dependent quantum particle, to a fluid system which is pseudo-barotropic, irrotational and inviscid. We first discuss the hydrodynamical properties of the Madelung description in general, and extract a pressure like term from the Bohm potential. We show that the existence of a pressure gradient force in the fluid description, does not violate Ehrenfest’s theorem since its expectation value is zero. We also point out that incompressibility of the fluid implies conservation (...) of density along a fluid parcel trajectory and in 1D this immediately results in the non-spreading property of wave packets, as the sum of Bohm potential and an exterior potential must be either constant or linear in space. Next we relate to the hydrodynamic description a thermodynamic counterpart, taking the classical behavior of an adiabatic barotopric flow as a reference. We show that while the Bohm potential is not a positive definite quantity, as is expected from internal energy, its expectation value is proportional to the Fisher information whose integrand is positive definite. Moreover, this integrand is exactly equal to half of the square of the imaginary part of the momentum, as the integrand of the kinetic energy is equal to half of the square of the real part of the momentum. This suggests a relation between the Fisher information and the thermodynamic like internal energy of the Madelung fluid. Furthermore, it provides a physical linkage between the inverse of the Fisher information and the measure of disorder in quantum systems—in spontaneous adiabatic gas expansion the amount of disorder increases while the internal energy decreases.

We examine whether the "evidence of evidence is evidence" principle is true. We distinguish several different versions of the principle and evaluate recent attacks on some of those versions. We argue that, whatever the merits of those attacks, they leave the more important rendition of the principle untouched. That version is, however, also subject to new kinds of counterexamples. We end by suggesting how to formulate a better version of the principle that takes into account those new counterexamples.

Scholars have proposed that incarceration rates might be reduced by a requirement that judges justify incarceration decisions with respect to their operational costs (e.g., prison capacity). In an Internet-based vignette experiment (N = 214), we tested this prediction by examining whether criminal punishment judgments (prison vs. probation) among university undergraduates would be influenced by a prompt to provide a justification for one's judgment, and by a brief message describing prison capacity costs. We found that (1) the justification prompt alone was (...) sufficient to reduce incarceration rates, (2) the prison capacity message also independently reduced incarceration rates, and (3) incarceration rates were most strongly reduced (by about 25%) when decision makers were asked to justify their sentences with respect to the expected capacity costs. These effects survived a test of robustness and occurred regardless of whether participants reported that prison costs should influence judgments of incarceration. At the individual crime level, the least serious crimes were most amenable to reconsideration for probation. These findings are important for policymakers attempting to manage high incarceration rates. (shrink)

Suppose we learn that we have a poor track record in forming beliefs rationally, or that a brilliant colleague thinks that we believe P irrationally. Does such input require us to revise those beliefs whose rationality is in question? When we gain information suggesting that our beliefs are irrational, we are in one of two general cases. In the first case we made no error, and our beliefs are rational. In that case the input to the contrary is misleading. In (...) the second case we indeed believe irrationally, and our original evidence already requires us to fix our mistake. In that case the input to that effect is normatively superfluous. Thus, we know that information suggesting that our beliefs are irrational is either misleading or superfluous. This, I submit, renders the input incapable of justifying belief revision, despite our not knowing which of the two kinds it is. (shrink)

The Madelung equations map the non-relativistic time-dependent Schrödinger equation into hydrodynamic equations of a virtual fluid. While the von Neumann entropy remains constant, we demonstrate that an increase of the Shannon entropy, associated with this Madelung fluid, is proportional to the expectation value of its velocity divergence. Hence, the Shannon entropy may grow due to an expansion of the Madelung fluid. These effects result from the interference between solutions of the Schrödinger equation. Growth of the Shannon entropy due to expansion (...) is common in diffusive processes. However, in the latter the process is irreversible while the processes in the Madelung fluid are always reversible. The relations between interference, compressibility and variation of the Shannon entropy are then examined in several simple examples. Furthermore, we demonstrate that for classical diffusive processes, the “force” accelerating diffusion has the form of the positive gradient of the quantum Bohm potential. Expressing then the diffusion coefficient in terms of the Planck constant reveals the lower bound given by the Heisenberg uncertainty principle in terms of the product between the gas mean free path and the Brownian momentum.

The Self-Intimation thesis has it that whatever justificatory status a proposition has, i.e., whether or not we are justified in believing it, we are justified in believing that it has that status. The Infallibility thesis has it that whatever justificatory status we are justified in believing that a proposition has, the proposition in fact has that status. Jointly, Self-Intimation and Infallibility imply that the justificatory status of a proposition closely aligns with the justification we have about that justificatory status. Self-Intimation (...) has two noteworthy implications. First, assuming that we never have sufficient justification for a proposition and for its negation, we can derive Infallibility from Self-Intimation. Interestingly, there seems to be no equivalently simple way to derive Self-Intimation from Infallibility. This asymmetry provides reason for thinking that bottom-level justification rather than top-level justification drives the explanation for why the levels of justification align. Second, Self-Intimation suggests a counterintuitive treatment of information concerning what justificatory status a proposition has. It follows from Self-Intimation that we always have justification for the truth about whether a proposition is justified for us, and therefore, that higher-order evidence could change what we should believe on this matter only by misleading us. This permits forming beliefs about whether a proposition is justified for us without regard to higher-order evidence, and thus reveals a reason for thinking that top-level justification is evidentially inert.

ABSTRACTShould conciliating with disagreeing peers be considered sufficient for reaching rational beliefs? Thomas Kelly argues that when taken this way, Conciliationism lets those who enter into a disagreement with an irrational belief reach a rational belief all too easily. Three kinds of responses defending Conciliationism are found in the literature. One response has it that conciliation is required only of agents who have a rational belief as they enter into a disagreement. This response yields a requirement that no one should (...) follow. If the need to conciliate applies only to already rational agents, then an agent must conciliate only when her peer is the one irrational. A second response views conciliation as merely necessary for having a rational belief. This alone does little to address the central question of what is rational to believe when facing a disagreeing peer. Attempts to develop the response either reduce to the first response, or deem necessary an unnecessary doxastic revision, or imply that rational dilemmas obtain in cases where intuitively there are none. A third response tells us to weigh what our pre-disagreement evidence supports against the evidence from the disagreement itself. This invites epistemic akrasia. (shrink)

In an attempt to explore further the Madelung fluid-like representation of quantum mechanics, we derive the small perturbation equations of the fluid with respect to its basic states. The latter are obtained from the Madelung transform of the Schrödinger equation eigenstates. The fundamental eigenstates of de Broglie monochromatic matter waves are then shown to be mapped into the simple basic states of a fluid with constant density and velocity, where the latter is the de Broglie group velocity. The normal modes (...) with respect to these basic states are derived and found to also satisfy the de Broglie dispersion relation. Despite being dispersive waves, their propagation mechanism is equivalent to that of sound waves in a classical ideal adiabatic gas. We discuss the physical interpretation of these results. (shrink)

The case study aims to reveal the praxis that serves the media during ethnic-violence conflicts. The article closely reads reports of the Israeli media covering the clashes between Israeli Arabs and the police, in the first days of the second Intifada. We analyze how mainstream Hebrew media covered the unfolding events, and also refer to reports in Arab-language newspapers. Two prominent trends shaped the frame through which events were reported: Inclusion and exclusion. Israel's Hebrew-language media excluded the Arab citizens from (...) the general Israeli public, while, at the same time, equating them with the residents of the Palestinian Authority. That is, the media framed the Arab Israeli citizens as Palestinians, blurring the line between the riots within Israel and the armed violence in the West Bank and Gaza. This coverage changed after the first and most intense days of riots; Israeli journalists then switched to a more civil framing after establishing an inner as well as an outer discourse. (shrink)

Here we investigate the classes RCA $^\uparrow_\alpha$ of representable directed cylindric algebras of dimension α introduced by Nemeti[12]. RCA $^\uparrow_\alpha$ can be seen in two different ways: first, as an algebraic counterpart of higher order logics and second, as a cylindric algebraic analogue of Quasi-Projective Relation Algebras. We will give a new, "purely cylindric algebraic" proof for the following theorems of Nemeti: (i) RCA $^\uparrow_\alpha$ is a finitely axiomatizable variety whenever α ≥ 3 is finite and (ii) one can obtain (...) a strong representation theorem for RCA $^\uparrow_\alpha$ if one chooses an appropriate (non-well-founded) set theory as foundation of mathematics. These results provide a purely cylindric algebraic solution for the Finitization Problem (in the sense of [11]) in some non-well-founded set theories. (shrink)

Phenotypic divergence among animal species may be due in part to species‐specific (SS) regulation of gene expression by small, non‐coding regulatory RNAs termed “microRNAs”. This phenomenon can be modulated by several variables. First, microRNA genes vary by their level of conservation, many of them being SS, or unique to a particular evolutionary lineage. Second, microRNA expression levels vary spatially and temporally in different species. Lastly, while microRNAs bind the 3′UTR of target genes in order to silence their expression, the binding (...) sites themselves are often non‐conserved. The variability of the miRNA‐target paradigm between different species is thus multifactorial, and this paradigm has only just started to gain attention from researchers in various fields. Here we present and discuss recent findings regarding the characteristics and implications of SS microRNA regulation. (shrink)

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

Let be a countable first order structure and endow the universe of with the discrete topology. Then the automorphism group of becomes a topological group. A tuple of automorphisms is defined to be weakly generic iff its diagonal conjugacy class (in the algebraic sense) is dense (in the topological sense) and the ‐orbit of each is finite. Existence of tuples of weakly generic automorphisms are interesting from the point of view of model theory as well as from the point of (...) view of finite combinatorics.The main results of the present work are as follows. In Theorem 2.6 we characterize the existence of tuples of weakly generic automorphisms with the aid of the profinite topology of free groups. In Corollary 2.12 we will show that if has finite topological rank r (and satisfies a further, mild technical condition) then the existence of a weakly generic tuple in implies the existence of weakly generic tuples in for all natural number. Finally, in Theorem 3.2 we show that if is a countable model of an ℵ0‐categorical, simple theory in which all types over the empty set are stationary and has a pair of weakly generic automorphisms then it has tuples of weakly generic automorphisms of arbitrary finite length.At the technical level we will combine elementary investigations about the profinite topology of free groups with the results of [11] about topological ranks of the automorphism groups of some structures.

Advances in artificial intelligence (AI) raise important questions about whether people view moral evaluations by AI systems similarly to human-generated moral evaluations. We conducted a modified Moral Turing Test (m-MTT), inspired by Allen et al. (Exp Theor Artif Intell 352:24–28, 2004) proposal, by asking people to distinguish real human moral evaluations from those made by a popular advanced AI language model: GPT-4. A representative sample of 299 U.S. adults first rated the quality of moral evaluations when blinded to their source. (...) Remarkably, they rated the AI’s moral reasoning as superior in quality to humans’ along almost all dimensions, including virtuousness, intelligence, and trustworthiness, consistent with passing what Allen and colleagues call the comparative MTT. Next, when tasked with identifying the source of each evaluation (human or computer), people performed significantly above chance levels. Although the AI did not pass this test, this was not because of its inferior moral reasoning but, potentially, its perceived superiority, among other possible explanations. The emergence of language models capable of producing moral responses perceived as superior in quality to humans’ raises concerns that people may uncritically accept potentially harmful moral guidance from AI. This possibility highlights the need for safeguards around generative language models in matters of morality. (shrink)

How are we to think of Beckett's fiction? Lyrical, inventive, uncompromising, beautifully precise-an immense achievement—is it really an art that proclaims the disintegration of language and of the imagination, as traditional readings conclude?

Beckett's fiction transposes a large intertextual logic from the Western metaphysics it is said to disown, and so takes its place in a literary and philosophical tradition that extends from Plato to (...) Joyce and Yeats. At the same time, it develops as a serial narrative, from the early novels to the late short fictions, to unravel the story itself that its metaphysical tradition tells. (shrink)

Purpose: To determine motives and attitudes towards life-sustaining treatments by clinical and preclinical medical students. Methods: This was a scenario-based questionnaire that presented patients with a limited life expectancy. The survey was distributed among 455 medical students in preclinical and clinical years. Students were asked to rate their willingness to perform LSTs and rank the motives for doing so. The effect of medical education was then investigated after adjustment for age, gender, religion, religiosity, country of origin, and marital status. Results: (...) Preclinical students had a significantly higher willingness to perform LSTs in all cases. This was observed in all treatments offered in cases of a metastatic oncologic patient and an otherwise healthy man after a traumatic brain injury. In the case of an elderly woman on long-term care, preclinical students had higher willingness to supply vasopressors but not perform an intubation, feed with a nasogastric tube, or treat with a continuous positive air-pressure ventilator. Both preclinical and clinical students had high willingness to perform resuscitation on a twelve-year-old boy with a TBI. Differences in motivation factors were also seen. Discussion: Preclinical students had a greater willingness to treat compared to clinical students in all cases and with most medical treatments offered. This is attributed mainly to changes along the medical curriculum. Changes in reasons for supplying LSTs were also documented. (shrink)

Many voting rules and, in particular, the plurality rule and Condorcet-consistent voting rules satisfy the simple-majority decisiveness property. The problem implied by such decisiveness, namely, the universal disregard of the preferences of the minority, can be ameliorated by applying unbiased scoring rules such as the classical Borda rule, but such amelioration has a price; it implies erosion in the implementation of the widely accepted majority principle . Furthermore, the problems of majority decisiveness and of the erosion in the majority principle (...) are not necessarily severe when one takes into account the likelihood of their occurrence. This paper focuses on the evaluation of the severity of the two problems, comparing simple-majoritarian voting rules that allow the decisiveness of the smallest majority larger than 1/2 and the classical Borda method of counts. Our analysis culminates in the derivation of the conditions that determine, in terms of the number of alternatives k, the number of voters n, and the relative (subjective) weight assigned to the severity of the two problems, which of these rules is superior in light of the dual majoritarian approach.

This paper merges the non-expected utility approach (Tversky and Kahneman, J Risk Uncertain 5:297–323, 1992 and Quiggin, J Econ Behav Organ 3:323–343, 1982) into Akerlof’s (Quart J Econ 84:488–500, 1970) model of Market for Lemons. We derive the results for different probability weighting functions and analyze the phenomenon of market failure in light of non-expected utility maximization. Our main finding suggests that when the proportion of traded lemons is high (low), the problem of market failure is mitigated (enhanced). In addition, (...) for the case of Cumulative Prospect Theory, we show that (a) the higher the loss aversion is, the more pronounced is the market failure; (b) gain-domain elevation is negatively related to the extent of market failure; and (c) the value function is (i) negatively monotonic in the gain-domain diminishing sensitivity parameter when the market is characterized by a high proportion of “peaches,” and (ii) positively monotonic in the loss-domain diminishing sensitivity parameter when the market is characterized by a high proportion of “lemons.”.

What it means for an action to have moral worth, and what is required for this to be the case, is the subject of continued controversy. Some argue that an agent performs a morally worthy action if and only if they do it because the action is morally right. Others argue that a morally worthy action is that which an agent performs because of features that make the action right. These theorists, though they oppose one another, share something important in (...) common. They focus almost exclusively on the moral worth of right actions. But there is a negatively valenced counterpart that attaches to wrong actions, which we will call moral counterworth. In this paper, we explore the moral counterworth of wrong actions in order to shed new light on the nature of moral worth. Contrary to theorists in both camps, we argue that more than one kind of motivation can affect the moral worth of actions. (shrink)

Among others we will prove that the equational theory of ω dimensional representable polyadic equality algebras (RPEA ω 's) is not schema axiomatizable. This result is in interesting contrast with the Daigneault-Monk representation theorem, which states that the class of representable polyadic algebras is finite schema-axiomatizable (and hence the equational theory of this class is finite schema-axiomatizable, as well). We will also show that the complexity of the equational theory of RPEA ω is also extremely high in the recursion theoretic (...) sense. Finally, comparing the present negative results with the positive results of Ildiko Sain and Viktor Gyuris [12], the following methodological conclusions will be drawn: The negative properties of polyadic (equality) algebras can be removed by switching from what we call the "polyadic algebraic paradigm" to the "cylindric algebraic paradigm".

Both left libertarians, who support the redistribution of income and wealth through taxation, and right libertarians, who oppose redistributive taxation, share an important view: that, looming catastrophes aside, the state must never redistribute any part of our body or our person without our consent. Cécile Fabre rejects that view. For her, just as the undeservedly poor have a just claim to money from their fellow citizens in order to lead a minimally flourishing life, the undeservedly ‘medically poor’ have a just (...) claim to help from fellow citizens in order to lead such a life. Such obligatory help may in principle involve even the supply of body parts for transplantation. The state ought to exact such resources from the medically rich whenever doing so would secure the prospect of a minimally flourishing life to the medically poor without denying that prospect to anyone else. Fabre criticizes Ronald Dworkin's belief in ‘a prophylactic line that comes close to making the body inviolate, that is, making body parts not parts of social resources at all’. For her, ‘Duties to help. . . do not stop at material resources: they involve the body. . . in invasive ways’. (shrink)
