Conspiracy theories are often portrayed as unwarranted beliefs, typically supported by suspicious kinds of evidence. Yet contemporary work in Philosophy argues provisional belief in conspiracy theories is at the very least understandable---because conspiracies occur---and that if we take an evidential approach, judging individual conspiracy theories on their particular merits, belief in such theories turns out to be warranted in a range of cases. -/- Drawing on this work, I examine the kinds of evidence typically associated with conspiracy theories, and show (...) how the so-called evidential problems with conspiracy theories are also problems for the kinds of evidence put forward in support of other theories. As such, if there is a problem with the conspiracy theorist's use of evidence, it is one of principle: is the principle which guides the conspiracy theorist's use of evidence somehow in error? I argue that whatever we might think about conspiracy theories generally, there is no prima facie case for a scepticism of conspiracy theories based purely on their use of evidence. (shrink)

Belief in conspiracy theories is typically considered irrational, and as a consequence of this, conspiracy theorists––those who dare believe some conspiracy theory––have been charged with a variety of epistemic or psychological failings. Yet recent philosophical work has challenged the view that belief in conspiracy theories should be considered as typically irrational. By performing an intra-group analysis of those people we call “conspiracy theorists”, we find that the problematic traits commonly ascribed to the general group of conspiracy theorists turn out to (...) be merely a set of stereotypical behaviours and thought patterns associated with a purported subset of that group. If we understand that the supposed prob- lem of belief in conspiracy theories is centred on the beliefs of this purported sub- set––the conspiracists––then we can reconcile the recent philosophical contribu- tions to the wider academic debate on the rationality of belief in conspiracy theories.

A theory of gender ought to be compatible with trans-inclusive definitions of gender identity terms, such as ‘woman’ and ‘man’. Appealing to this principle of trans-inclusion, Katharine Jenkins argues that we ought to endorse a dual social position and identity theory of gender. Here, I argue that Jenkins’s dual theory of gender fails to be trans-inclusive for the following reasons: it cannot generate a definition of ‘woman’ that extends to include all trans women, and it understands transgender gender identity through (...) a cisgender frame.

Traditional definitions of lying require that a speaker believe that what she asserts is false. Sam Fox Krauss seeks to jettison the traditional belief requirement in favour of a necessary condition given in a credence-accuracy framework, on which the liar expects to impose the risk of increased inaccuracy on the hearer. He argues that this necessary condition importantly captures nearby cases as lies which the traditional view neglects. I argue, however, that Krauss's own account suffers from an identical drawback of (...) being unable to explain nearby cases; and even worse, that account fails to distinguish cases of telling lies from cases of telling the truth.

In this chapter, we follow Edward Craig?s advice: ask what the concept of knowledge does for us and use our findings as clues about its application conditions. What a concept does for us is a matter of what we can do with it, and what we do with concepts is deploy them in thought and language. So, we will examine the purposes we have in attributing knowledge. This chapter examines two such purposes, agent evaluation and informant-suggestion, and brings the results (...) to bear on an important debate about the application conditions of the concept of knowledge?the debate between contextualists and their rivals.

This article discusses the adequacy of Rawls’ theory of justice as a tool for racial justice. It is argued that critics like Charles W Mills fail to appreciate both the insights and limits of the Rawlsian framework. The article has two main parts spread out over several different sections. The first is concerned with whether the Rawlsian framework suffices to prevent racial injustice. It is argued that there are reasons to doubt whether it does. The second part is concerned with (...) whether a Rawlsian framework has the resources to rectify past racial injustice. It is argued that it has more resources to do this than Mills allows. This second part of the article centers on two Rawlsian ideas: ideal theory and the fair equality of opportunity principle. It is argued that ideal theory is essential for the kind of rectificatory work that Mills wants nonideal theory to do, and that where there is a socioeconomic legacy of past injustice, it is hard to see how FEO could be implemented if it did no rectificatory work, a result which means that there is less need to turn to nonideal theory at all.

Contemporary scholarship concerning science diplomacy is increasingly taking a historical approach. In our introduction to this special issue, we argue that this approach promises insight into science diplomacy because of the tools historians of science bring to their work. In particular, we observe that not only are historians of science currently poised to chart the diplomatic aspects involved in the transnational circulation of technoscientific knowledge, materials, and expertise. They are ready to bring critical global analysis to an important phenomenon that (...) has too often been treated as a benign diplomacy device deployed by the Global North without equal reference to the Global South. Through cases discussed in the articles of the special issue, however, we see that historically, in the Global South as well as the Global North, science diplomacy has often functioned to mediate the circulation of technoscientific knowledge and materials, and its historical study helps to better illuminate the resulting knowledge-power nexus.

I defend affirmative action on the ground that it increases certain people’s ability to exercise their basic liberties, rather than because it rectifies injustice in the narrow context of educational admission procedures. I present this justification using a Rawlsian contractualist framework to forge a “nonideal principle of justice.” Drawing on social science, I argue that this principle supports affirmative-action policies like those in the contemporary U.S., and blocks the objection that such policies are unfair. In closing, I show how my (...) account can be used to refine some features of contemporary affirmative-action policies, and I reflect more generally on the value of nonideal principles of justice for tackling exigent topics.

This paper explains three ways to develop a conceptual role view of meaning in metaethics. First, it suggests that there’s a way to combine inspiration from noncognitivism with a particular form of the conceptual role view to form a noncognitivist view with distinctive advantages over other noncognitivist views. Second, it suggests that there’s also a way to combine a strong commitment to cognitivism with a different form of the conceptual role view to form a version of cognitivism with distinctive advantages (...) over other cognitivist views. Finally, it suggests that there's another way to think of the conceptual role view in metaethics is as opening up the space for a third way, beyond cognitivism and noncognitivism. (shrink)

Standard accounts of the senses attempt to answer the question how and why we count five senses ; none of the standard accounts is satisfactory. Any adequate account of the senses must explain the significance of the senses, that is, why distinguishing different senses matters. I provide such an explanation, and then use it as the basis for providing an account of the senses and answering the counting question.

Prioritarianism is an ethical theory that gives extra weight to the well-being of the worse off. In contrast, dominant policy-evaluation methodologies, such as benefit-cost analysis, cost-effectiveness analysis, and utilitarianism, ignore or downplay issues of fair distribution. Based on a research group founded by the editors, this important book is the first to show how prioritarianism can be used to assess governmental policies and evaluate societal conditions. This book uses prioritarianism as a methodology to evaluate governmental policy across a variety of (...) policy domains: taxation, health policy, risk regulation, education, climate policy, and the COVID-19 pandemic. It is also the first to demonstrate how prioritarianism improves on GDP as an indicator of a society's progress over time. Edited by two senior figures in the field with contributions from some of the world's leading economists, this volume bridges the gap from the theory of prioritarianism to its practical application.

In recent decades, scholars of Buddhist philosophy have frequently treated the Trisvabhāvanirdeśa, or “Teaching of the Three Natures,” attributed to Vasubandhu, as an authentic and authoritative representation of that celebrated thinker’s mature work within the Yogācāra tradition. However, serious questions may be posed concerning the status and authority of the TSN within Yogācāra, its true authorship, and the relation of its contents to trends in early Yogācāra thought. In the present article, we review the actual state of our knowledge of (...) the TSN’s possible origins, considering, too, the implications this may have for contemporary treatments thereof.

Many philosophers hold constitutive theories of self-knowledge in the sense that they think either that a person’s psychological states depend upon her having true beliefs about them, or that a person’s believing that she is in a particular psychological state depends upon her actually being in that state. One way to support this type of view can be found in Shoemaker’s well-known argument that an absurd condition, which he calls “self-blindness”, would be possible if a subject’s psychological states and her (...) higher-order beliefs about them were wholly distinct existences. A second reason to endorse a constitutive theory is the widespread conviction that first-person access is epistemically special. In this essay, I shall argue that even if self-blindness is impossible, the best explanation for this does not deny that a person’s psychological states are wholly distinct from her beliefs about them. I shall then attempt to account for the epistemic distinctiveness of first-person access on the basis of fundamental features of rational cognition. One advantage of this account over constitutive theories of self-knowledge is that it is better placed to explain our fallibility and ignorance. (shrink)

Previous findings indicate that negative arousal enhances bottom-up attention biases favouring perceptual salient stimuli over less salient stimuli. The current study tests whether those effects were driven by emotional arousal or by negative valence by comparing how well participants could identify visually presented letters after hearing either a negative arousing, positive arousing or neutral sound. On each trial, some letters were presented in a high contrast font and some in a low contrast font, creating a set of targets that differed (...) in perceptual salience. Sounds rated as more emotionally arousing led to more identification of highly salient letters but not of less salient letters, whereas sounds’ valence ratings did not impact salience biases. Thus, arousal, rather than valence, is a key factor enhancing visual processing of perceptually salient targets. (shrink)

Local food is often defended on environmental grounds. However, environmental defenses of local food are flawed, and all environmental defenses are limited as they at most establish that local food is instrumentally valuable. These deficiencies motivate a different approach. By drawing on the aesthetics of engagement, a theory of environmental aesthetics, I argue that local food has an overlooked intrinsic value; it can allow people to become engaged with—and thereby aesthetically appreciate—the environment. My argument charts a comparatively neglected area of (...) aesthetics: the aesthetics of taste and smell and, more specifically, the role that these senses play in the aesthetic appreciation of the environment.

Non-naturalists face a dilemma. They either leave their normative views hostage to a non-natural realm, which is immoral, or they do not, which is irrational. David Enoch has argued that the problem rests on cases of junk knowledge — conditionals that cannot be used to expand knowledge via modus ponens. Camil Golub has suggested that the dilemma rests on questionable assumptions about how we might come to know about the non-natural. Here I reply to these worries, sharpen the dilemma, and (...) situate it in the literature on doxastic wrongs. (shrink)

This Article provides a comprehensive, critical overview of proposals to use happiness surveys for steering public policy. Happiness or “subjective well-being” surveys ask individuals to rate their present happiness, life-satisfaction, affective state, etc. A massive literature now engages in such surveys or correlates survey responses with individual attributes. And, increasingly, scholars argue for the policy relevance of happiness data: in particular, as a basis for calculating aggregates such as “gross national happiness,” or for calculating monetary equivalents for non-market goods based (...) on coefficients in a happiness equation. But is individual well-being equivalent to happiness? The happiness literature tends to blur or conflate important concepts: well-being, subjective well-being, happiness, utility, satisfaction. A preference-realization account of well-being denies the equivalence of happiness and welfare, since someone can have preferences for non-mental attributes, such as health, autonomy, goal-fulfillment, knowledge or the quality of her relationships. It is critical, therefore, to differentiate two potential policy roles for happiness surveys. First, the survey response may provide prima facie evidence of the respondent’s preference-utility: the extent to which her preferences are realized. Second, it may indicate her experience-utility: the quality of her mental states. The Article clarifies these two, very different, ideas. It then criticizes, in turn, the preference-utility and the experience-utility defenses of the policy relevance of happiness surveys. Enthusiasm about happiness is premature. (shrink)

In the processing of subject-verb agreement, non-subject plural nouns following a singular subject sometimes “attract” the agreement with the verb, despite not being grammatically licensed to do so. This phenomenon generates agreement errors in production and an increased tendency to fail to notice such errors in comprehension, thereby providing a window into the representation of grammatical number in working memory during sentence processing. Research in this topic, however, is primarily done in related languages with similar agreement systems. In order to (...) increase the cross-linguistic coverage of the processing of agreement, we conducted a self-paced reading study in Modern Standard Arabic. We report robust agreement attraction errors in relative clauses, a configuration not particularly conducive to the generation of such errors for all possible lexicalizations. In particular, we examined the speed with which readers retrieve a subject controller for both grammatical and ungrammatical agreeing verbs in sentences where verbs are preceded by two NPs, one of which is a local non-subject NP that can act as a distractor for the successful resolution of subject-verb agreement. Our results suggest that the frequency of errors is modulated by the kind of plural formation strategy used on the attractor noun: nouns which form plurals by suffixation condition high rates of attraction, whereas nouns which form their plurals by internal vowel change (ablaut) generate lower rates of errors and reading-time attraction effects of smaller magnitudes. Furthermore, we show some evidence that these agreement attraction effects are mostly contained in the right tail of reaction time distributions. We also present modeling data in the ACT-R framework which supports a view of these ablauting patterns wherein they are differentially specified for number and evaluate the consequences of possible representations for theories of grammar and parsing.

:Preference-aggregation problems arise in various contexts. One such context, little explored by social choice theorists, is metaethical. ‘Ideal-advisor’ accounts, which have played a major role in metaethics, propose that moral facts are constituted by the idealized preferences of a community of advisors. Such accounts give rise to a preference-aggregation problem: namely, aggregating the advisors’ moral preferences. Do we have reason to believe that the advisors, albeit idealized, can still diverge in their rankings of a given set of alternatives? If so, (...) what are the moral facts when the advisors do diverge? These questions are investigated here using the tools of Arrovian social choice theory. (shrink)

According to cognitive non-naturalism, normative judgments are standard beliefs that purport to be about non-natural properties. An influential plurality of normative theorists, including non-naturalist realists, error theorists and skeptics, share this view. But it is mistaken. For it predicts an epistemic profile for normative judgments that they do not have. In particular, they are not disposed to extinguish in light of accepted evidence that the any non-natural properties are absent, and they are not disposed to come into existence in light (...) of accepted evidence for any non-natural property. So normative judgments might be beliefs, and there might be non-natural properties, but normative judgments are not beliefs about non-natural properties. (shrink)

During the latter-half of the nineteenth century, the utility of the house sparrow to humankind was a contentious topic. In Britain, numerous actors from various backgrounds including natural history, acclimatisation, agriculture and economic ornithology converged on the bird, as contemporaries sought to calculate its economic cost and benefit to growers. Periodicals and newspapers provided an accessible and anonymous means of expression, through which the debate raged for over 50 years. By the end of the century, sparrows had been cast as (...) detrimental to agriculture. Yet consensus was not achieved through new scientific methods, instruments, or changes in practice. This study instead argues that the rise and fall of scientific disciplines and movements paved the way for consensus on “the sparrow question.” The decline of natural history and acclimatisation stifled a raging debate, while the rising science of economic ornithology sought to align itself with agricultural interests: the latter overwhelmingly hostile to sparrows.

Complex life cycles are common in the eukaryotic world, and they complicate the question of how to define individuality. Using a bottom-up, gene-centric approach, I consider the concept of fitness in the context of complex life cycles. I analyze the fitness effects of an allele on different biological units within a complex life history and how these effects drive evolutionary change within populations. Based on these effects, I attempt to construct a concept of fitness that accurately predicts evolutionary change in (...) the context of complex life cycles. (shrink)

A number of philosophers have argued that causation is not an objective feature of the microphysical world but rather is a perspectival phenomenon that holds only between “coarse-grained” entities such as those that figure in the special sciences. This view seems to pose a problem for arguments for physicalism that rely on the alleged causal completeness of physics. In this paper, I address this problem by arguing that the completeness of physics has two components, only one of which is causal. (...) These two components of completeness can be used in an argument for physicalism that is supported by strong inductive evidence even in the absence of microphysical causation. (shrink)

We defend a scalar theory of the relationship between material scarcity and justice. As scarcity increases beyond a specified threshold, we argue that deontological egalitarian constraints should be gradually relaxed and consequentialist considerations should increasingly determine distributions. We construct this theory by taking a bottom-up approach that is guided by principles of medical triage. Armed with this theory, we consider the range of conditions under which justice applies. We argue that there are compelling reasons for thinking that justice applies under (...) a far broader range of conditions than is standardly supposed, including those that could sensibly be labelled as conditions of extreme rather than moderate scarcity.

This paper explores the phenomenology of the Capgras and Cotard delusions. The former is generally characterised as the belief that relatives or friends have been replaced by impostors, and the latter as the conviction that one is dead or has ceased to exist. A commonly reported feature of these delusions is an experienced ''defamiliarisation'' or even ''derealisation'' of things, which is associated with an absence or distortion of affect. I suggest that the importance attributed to affect by current explanations of (...) delusional experience can serve to make explicit the manner in which we ordinarily experience the world under a taken-for-granted aspect of affective familiarity. This implicit feeling is, I argue, partly constitutive of our sense of reality. However, so-called ''folk psychology,'' which is generally adopted by philosophers as an initial interpretive backdrop for delusional beliefs and for beliefs more generally, fails to accommodate it. As a consequence, some pervasive philosophical assumptions concerning the manner in which we experience and understand the world, ourselves, and each other are called into question. (shrink)

Type specimens are used to designate species. What is the nature of the relation between a type specimen and the species it designates? If species names are rigid designators, and type specimens ostensively define species, then that relation is, at the very least, a close one. Levine :325–338, 2001) argues that the relationship of type specimen to a named species is one of necessity—and that this presents problems for the individuality thesis. Namely, it seems odd that a contingently selected specimen (...) should belong to a species of necessity. In considering Levine’s argument, LaPorte suggests that recognizing the distinction between de re and de dicto necessity resolves Levine’s worries. I reconsider the motivating question: does a type specimen belong of necessity to the species that it designates? In light of taxonomic cases and practice the answer is clear: definitively not. This is particularly clear in the case of re-designation of types by taxonomic decree. I explain how this helps reveal how taxonomists prioritize competing theoretical commitments, and offer a defense of the individuality thesis as applied to these particular cases. In short, I demonstrate how to misidentify a type specimen. (shrink)

Devin Zane Shaw’s new book Egalitarian Moments is an attempt to think with and through Jacques Rancière. Shaw’s highly original interpretation of Rancière opens space within Rancière’s thought for a new, expanded account of the politics of art and literature, and Shaw is then able to use this theory as a way of rereading the history of philosophy. Shaw’s project is ultimately an attempt to show that it is possible to do philosophy in an egalitarian way – that not all (...) political philosophy need be “political philosophy” in Rancière’s pejorative sense – and that philosophy can serve as a vital resource for egalitarian political movements.

This paper explores a fundamental similarity between cognitive models for crying and conceptions of insight, enlightenment or, in the context of art, “aesthetic experience.” All of which center on a process of initial discrepancy, followed by schema change, and conclude in a personal adjustment or a “transformation” of one’s image of the self. Because tears are argued to mark one of the only physical indicators of this cognitive outcome, and because the process is particularly salient in examples with art, I (...) argue that crying may provide an intriguing marker for empirical study of perceiving art. To explore this parallel, I offer a review of crying theory as well as of tearful cases with art, pointing out the key cognitive elements. I then introduce an expanded crying model, based upon our recent model of art experience which does consider insight and adjustment or application of the self. I also consider multiple emotional and evaluative factors, which may co-vary with crying response. This theoretical discussion is then applied in three exploratory, survey-based studies, conducted within U.K., Japan and U.S. museums, and including what is claimed to be the 20th century’s most tear-inducing abstract paintings. Results showed—with cross-cultural consistency—significant correlation between “feeling like crying” and a collection of responses posited to indicate a full progression to aesthetic experience. This also found correlation to positive assessment of artwork goodness, beauty, understanding of meaning, and to final reported self reflection and epiphany. I argue that, beyond the question of why we may cry, by considering implications of what tears may indicate for information processing, feeling like crying may be a compelling basis for identifying outcomes of perceptual (art) experience.

In ‘Computing Machinery and Intelligence’, Turing, sceptical of the question ‘Can machines think?’, quickly replaces it with an experimentally verifiable test: the imitation game. I suggest that for such a move to be successful the test needs to be relevant, expansive, solvable by exemplars, unpredictable, and lead to actionable research. The Imitation Game is only partially successful in this regard and its reliance on language, whilst insightful for partially solving the problem, has put AI progress on the wrong foot, prescribing (...) a top-down approach for building thinking machines. I argue that to fix shortcomings with modern AI systems a nonverbal operationalisation is required. This is provided by the recent Animal-AI Testbed, which translates animal cognition tests for AI and provides a bottom-up research pathway for building thinking machines that create predictive models of their environment from sensory input.

Moral courage involves acting in the service of one’s convictions, in spite of the risk of retaliation or punishment. I suggest that moral courage also involves a capacity to face others as moral agents, and thus in a manner that does not objectify them. A moral stand can only be taken toward another moral agent. Often, we find ourselves unable to face others in this way, because to do so is frightening, or because we are consumed by blinding anger. But (...) without facing others as moral subjects, we risk moral cowardice on the one hand and moral fanaticism on the other. (shrink)

The COVID-19 crisis has forced a difficult trade-off between limiting the health impacts of the virus and maintaining economic activity. Welfare economics offers tools to conceptualize this trade-off so that policy-makers and the public can see clearly what is at stake. We review four such tools: the Value of Statistical Life (VSL); the Value of Statistical Life Years (VSLYs); Quality-Adjusted Life-Years (QALYs); and social welfare analysis, and argue that the latter are superior. We also discuss how to choose policies that (...) differentially affect people’s wellbeing. We argue in favor of evaluating policies using a Social Welfare Function (SWF), which evaluates the possible distributions of wellbeing across individuals that may result from a policy. Such a function, we argue, should regard increases in the wellbeing of the less well-off as especially valuable. We then use a model to illustrate how such a framework can help evaluate two broad policy types in response to the pandemic: eradication of the virus, and more lenient control of the spread. Our model reveals how such evaluations depend on many empirical facts but also on key value judgments about the relative importance of health and on the extent of special concern for the worse off. The purpose of this brief is not to make precise recommendations, as conditions vary widely across countries and over time, but to provide a methodology. (shrink)

My aim is to question an assumption that is often made in the philosophical literature on dispositions. This is the assumption that, generally, the stimulation (or ‘triggering’) of a disposition temporally precedes the manifesting of that disposition. I will begin by examining precisely what the trigging of a disposition may be thought to consist in, and will identify two plausible views. I will then argue that on either of these views about triggering, a case can be made against the view (...) that the triggering of a disposition always occurs before the manifesting of that disposition. More precisely, if the first view about triggering is accepted, and certain plausible assumptions about dispositions are put into place, a metaphysical argument can be formulated for the claim that the stimulation of a disposition never occurs before that disposition manifests. If the second view about triggering is accepted, the question concerning simultaneity becomes an empirical one. There are, however, examples of dispositional interaction which, on the second view about triggering, clearly seem to involve simultaneity.1. (shrink)

In this article applied and theoretical epistemologies benefit each other in a study of the British legal case of R. vs. Clark. Clark's first infant died at 11 weeks of age, in December 1996. About a year later, Clark had a second child. After that child died at eight weeks of age, Clark was tried for murdering both infants. Statisticians and philosophers have disputed how to apply Bayesian analyses to this case, and thereby arrived at different judgments about it. By (...) dwelling on this applied case, I make theoretical gains: clarifying and defending pragmatic principles of inference that are important for estimating key probabilities in a range of cases. Then, partly by drawing on such principles, and uncovering overlooked data on post-partum psychosis, I make applied gains: improving the rationality of judgments about the Sally Clark case in particular, judgments important to future similar cases.

Counterfactual thinking involves imagining hypothetical alternatives to reality. Philosopher David Lewis argued that people estimate the subjective plausibility that a counterfactual event might have occurred by comparing an imagined possible world in which the counterfactual statement is true against the current, actual world in which the counterfactual statement is false. Accordingly, counterfactuals considered to be true in possible worlds comparatively more similar to ours are judged as more plausible than counterfactuals deemed true in possible worlds comparatively less similar. Although Lewis (...) did not originally develop his notion of comparative similarity to be investigated as a psychological construct, this study builds upon his idea to empirically investigate comparative similarity as a possible psychological strategy for evaluating the perceived plausibility of counterfactual events. More specifically, we evaluate judgments of comparative similarity between episodic memories and episodic counterfactual events as a factor influencing people's judgments of plausibility in counterfactual simulations, and we also compare it against other factors thought to influence judgments of counterfactual plausibility, such as ease of simulation and prior simulation. Our results suggest that the greater the perceived similarity between the original memory and the episodic counterfactual event, the greater the perceived plausibility that the counterfactual event might have occurred. While similarity between actual and counterfactual events, ease of imagining, and prior simulation of the counterfactual event were all significantly related to counterfactual plausibility, comparative similarity best captured the variance in ratings of counterfactual plausibility. Implications for existing theories on the determinants of counterfactual plausibility are discussed. (shrink)

The extended Church-Turing thesis posits that any computable function can be calculated efficiently by a probabilistic Turing machine. If this thesis held true, the global effort to build quantum computers might ultimately be unnecessary.

BosonSampling - the sampling from a distribution of n photons undergoing some linear-optical process - is a recently developed, and experimentally accessible example of (...) such a task [1].

Recent philosophical discussions of intersubjectivity generally start by stating or assuming that our ability to understand and interact with others is enabled by a ‘folk psychology’ or ‘theory of mind’. Folk psychology is characterized as the ability to attribute intentional states, such as beliefs and desires, to others, in order to predict and explain their behaviour. Many authors claim that this ability is not merely one amongst many constituents of interpersonal understanding but an underlying core that enables social life. For (...) example, Churchland states that folk psychology ‘embodies our baseline understanding’ of others. Currie and Sterelny similarly assert that ‘our basic grip on the social world depends on our being able to see our fellows as motivated by beliefs and desires we sometimes share and sometimes do not’. And, as Frith and Happé put it, ‘this ability appears to be a prerequisite for normal social interaction: in everyday life we make sense of each other’s behaviour by appeal to a belief-desire psychology’.
