Despite the growing importance of ‘social value’ as a central feature of research ethics, the term remains both conceptually vague and to a certain extent operationally rigid. And yet, perhaps because the rhetorical appeal of social value appears immediate and self-evident, the concept has not been put to rigorous investigation in terms of its definition, strength, function, and scope. In this article, we discuss how the anthropological concept of liminality can illuminate social value and differentiate and reconfigure its variegated approaches. (...) Employing liminality as a heuristic encourages a reassessment of how we understand the mobilization of ‘social value’ in bioethics. We argue that social value as seen through the lens of liminality can provide greater clarity of its function and scope for health research. Building on calls to understand social value as a dynamic, rather than a static, concept, we emphasize the need to appraise social value iteratively throughout the entire research as something that transforms over multiple times and across multiple spaces occupied by a range of actors.

"One of the outstanding authorities on the early days of the Republic, Saul K. Padover offers in this volume a generous sampling of the letters, essays, speeches, discourses, and personal documents--many of them previously unpublished--of the men who made America. Included are extensive selections from the papers and speeches of John Adams, Benjamin Franklin, Alexander Hamilton, Thomas Jefferson, James Madison, and George Washington. There are also copious extracts from the private and public utterances of secondary, but important, figures of (...) the founding days--Samuel Adams, Elbridge Gerry, Patrick Henry, John Dickinson, Oliver Ellsworth, William Paterson, Benjamin Rush, George Wythe, and many others. A number of the speeches made at the Constitutional Convention in 1787 are given in full, and several of the important debates are reproduced. John Dickinson's Letters from an American Farmer in Pennsylvania appear in these pages as well as many of Alexander Hamilton's famous and brief opinions. Also included are John Hancock's speech on the Boston Massacre; Thomas Jefferson's Notes on Virginia; James Madison's Memorial against Religious Assessments; two of the most important of John Marshall's Supreme Court decisions (Marbury vs. Madison and McCulloch vs. Maryland); Robert Morris' Letters on Finance; John Taylor's paper On Aristocracy, and William Paterson's Plan for a Constitution. Taken together, these writings offer in one volume a complete picture of the thinking, the debate, the legal maneuvers, the compromises, the manners, and the morals of the American nation's earliest days. The book provides a sound basic appreciation of the atmosphere in which the Founding Fathers worked and planned and debated with one another. All the many counter-currents that contributed to the building of the Constitution, the stresses to which the young nation was subjected, the rebellion that continued to seethe, the moral climate of the days--these are all recreated in the speeches and writings of America's first patriots. Dr. Padover has bound the selections together with enlightening commentary that enables the reader to understand the exact circumstances of each utterance and brings the particular work into historical perspective."--Jacket.

Can quantum theory provide examples of metaphysical indeterminacy, indeterminacy that obtains in the world itself, independently of how one represents the world in language or thought? We provide a positive answer assuming just one constraint of orthodox quantum theory: the eigenstate-eigenvalue link. Our account adds a modal condition to preclude spurious indeterminacy in the presence of superselection sectors. No other extant account of metaphysical indeterminacy in quantum theory meets these demands.

We implement a recent characterization of metaphysical indeterminacy in the context of orthodox quantum theory, developing the syntax and semantics of two propositional logics equipped with determinacy and indeterminacy operators. These logics, which extend a novel semantics for standard quantum logic that accounts for Hilbert spaces with superselection sectors, preserve different desirable features of quantum logic and logics of indeterminacy. In addition to comparing the relative advantages of the two, we also explain how each logic answers Williamson’s challenge to any (...) substantive account of determinacy: For any proposition p, what could the difference between “p” and “it’s determinate that p” ever amount to? (shrink)

Recently, we (Synthese, 199(5–6):13247–13281, 2021) proposed Kripke-like semantics for two quantum logics of interderminacy. These logics expand the vocabulary of standard Birkhoff-von Neumann propositional quantum logic with a pair of modal operators interpreted as “it is (in)determinate that”, allowing them to express in the object language statements such as “it is indeterminate that system S is spin-up in the x-direction”, as well as statements of any logical complexity involving ascriptions of (in)determinacy. We present an axiomatization of a logic closely related (...) to one of these quantum logics of indeterminacy and prove that this axiomatization is sound and complete with respect to the Kripke-like semantics. We then prove that this logic is decidable. (shrink)

Orthodox quantum theory tells us that properties of quantum systems are represented by self-adjoint operators, and that two properties are incompatible just in case their respective operators do not commute. We present a puzzle for this orthodoxy, pinpointing the exact assumptions at play. Our solution to the puzzle specifically challenges the assumption that non-commuting operators represent incompatible properties. Instead, they represent incompatible levels of specification of determinates for a single determinable. This solution yields insight into the nature of so-called quantum (...) indeterminacy and demonstrates a new and fruitful application of the determinable-determinate relation in quantum theory.

Can a belief source confer justification when we lack antecedent justification for believing that it’s reliable? A negative answer quickly leads to skepticism. A positive answer, however, seems to commit one to allowing pernicious reasoning known as “epistemic bootstrapping.” Puzzles surrounding bootstrapping arise because we illicitly assume either that justification requires doxastic awareness of a source’s epistemic credentials or that there is no requirement that a subject be aware of these credentials. We can resolve the puzzle by splitting the horns (...) and requiring a non-conceptual awareness of, or direct acquaintance with, a source’s legitimacy. Requiring non-conceptual as opposed to doxastic awareness halts the regress and avoids the skeptical results. On the other hand, requiring non-conceptual awareness also guarantees that we are aware of evidence for a source’s reliability prior to using that source to form justified beliefs; we thereby avoid the problem of allowing epistemic bootstrapping to generate the illicit gains in justification.

According to Phenomenal Conservatism (PC), if it seems to a subject S that P, S thereby has some degree of (defeasible) justification for believing P. But what is it for P to seem true? Answering this question is vital for assessing what role (if any) such states can play. Many have appeared to adopt a kind of non-reductionism that construes seemings as intentional states which cannot be reduced to more familiar mental states like beliefs or sensations. In this paper I (...) aim to show that reductive accounts need to be taken more seriously by illustrating the plausibility of identifying seemings and conscious inclinations to form a belief. I briefly close the paper by considering the implications such an analysis might have for views such as PC. (shrink)

Some philosophers argue that we should eschew cross-explanatory integrations of mechanistic, dynamicist, and psychological explanations in cognitive science, because, unlike integrations of mechanistic explanations, they do not deliver genuine, cognitive scientific explanations. Here I challenge this claim by comparing the theoretical virtues of both kinds of explanatory integrations. I first identify two theoretical virtues of integrations of mechanistic explanations—unification and greater qualitative parsimony—and argue that no cross-explanatory integration could have such virtues. However, I go on to argue that this is (...) only a problem for those who think that cognitive science aims to specify one fundamental structure responsible for cognition. For those who do not, cross-explanatory integration will have at least two theoretical virtues to a greater extent than integrations of mechanistic explanations: explanatory depth and applicability. I conclude that one’s views about explanatory integration in cognitive science cannot be segregated from one’s views about the explanatory task of cognitive science. (shrink)

Machery and Weiskopf argue that the kind concept is a natural kind if and only if it plays an explanatory role in cognitive scientific explanations. In this paper, we argue against this explanationist approach to determining the natural kind-hood of concept. We first demonstrate that hybrid, pluralist, and eliminativist theories of concepts afford the kind concept different explanatory roles. Then, we argue that we cannot decide between hybrid, pluralist, and eliminativist theories of concepts, because each endorses a different, but equally (...) viable, specification of the explananda of cognitive science. It follows that an explanationist approach to determining the natural kind-hood of concept fails, because there is no consensus about whether or not concept should be afforded an explanatory role in our best cognitive scientific explanations. We conclude by considering what our critique of explanationism could imply for further discussions about the explanatory role of concepts in cognitive science. (shrink)

Some philosophers argue that all concepts cannot have the same representational structure, because no single kind of representation has been successful in accounting for the phenomena related to the formation and application of concepts. Here, I argue against this “appeal to cognitive science” by demonstrating that different theories of the kind concept cohere with different interpretations of the argument. To circumvent the threat of relativism, I argue that theories of concept should be understood as working hypotheses, which are provisionally accepted (...) to facilitate the investigation and explanation of the mind/brain. From this perspective, theories of concept are to be evaluated as part of a comparative analysis of the different kinds of cognitive science they inspire. (shrink)

Representationalists and anti-representationalists disagree about whether a naturalisation of mental content is possible and, hence, whether positing mental representations in cognitive science is justified. Here, I develop a novel way to think about mental representations based on a philosophical description of (cognitive) science inspired by cognitive instrumentalism. On this view, our acceptance of theories positing mental representations and our beliefs in (something like) mental representations do not depend on the naturalisation of content. Thus, I conclude that if we endorse cognitive (...) instrumentalism about mental representations, then we can finally leave the dispute between representationalism and anti-representationalism behind.

Public health and service delivery programmes, interventions and policies (collectively, ‘programmes’) are typically developed and implemented for the primary purpose of effecting change rather than generating knowledge. Nonetheless, evaluations of these programmes may produce valuable learning that helps determine effectiveness and costs as well as informing design and implementation of future programmes. Such studies might be termed ‘opportunistic evaluations’, since they are responsive to emergent opportunities rather than being studies of interventions that are initiated or designed by researchers. However, current (...) ethical guidance and registration procedures make little allowance for scenarios where researchers have played no role in the development or implementation of a programme, but nevertheless plan to conduct a prospective evaluation. We explore the limitations of the guidance and procedures with respect to opportunistic evaluations, providing a number of examples. We propose that one key missing distinction in current guidance is moral responsibility: researchers can only be held accountable for those aspects of a study over which they have control. We argue that requiring researchers to justify an intervention, programme or policy that would occur regardless of their involvement prevents or hinders research in the public interest without providing any further protections to research participants. We recommend that trial consent and ethics procedures allow for a clear separation of responsibilities for the intervention and the evaluation. (shrink)

This paper develops a version of the acquaintance theory of introspective justification. In the process, it rejects the view that acquaintance is sui generic in favor of a view that identifies acquaintance with availability for selection by attention mechanisms. Moreover, unlike many recent accounts of knowledge by acquaintance, it explains the epistemic significance of acquaintance in terms of the epistemic basing relation without any need to appeal to the structure or existence of phenomenal concepts. Lastly, while in ideal cases acquaintance (...) will provide a kind of infallible justification, the paper shows how to extend these ideas to allow that acquaintance can provide fallible introspective justification.

Many of our beliefs are the product of inference and depend on chains of reasoning from other beliefs we hold. Inferential internalism is the view that an inference can only provide justification if one is aware of the support relation that holds between the premises and conclusion. This inferential internalist requirement is controversial even among epistemologists who accept internalist conditions on justification more generally. In this paper, we argue that the intuition underlying a central motivation for internalism more generally is (...) the same intuition that motivates inferential internalism. As such, internalists who reject the more demanding requirements of inferential internalism are prima facie involved in a problematic inconsistency. We finish the paper by considering a dilemma for inferential internalism and presenting two strategies for responding. (shrink)

Kaplan and Craver :601–627, 2011) and Piccinini and Craver :283–311, 2011) argue that only mechanistic explanations of cognition are genuine causal explanations, because only evidence of mechanisms reveals the causal structure of cognition. I first argue that this claim is grounded in a commitment to the mechanistic account of causality, which cannot be endorsed by a defender of causal-nonmechanistic explanations. Then, I defend the epistemic theory of causality, which holds that causal explanations are not genuine to the extent that they (...) reveal mechanistic causal structure, but, rather, to the extent that they have evidential support and yield successful prediction, explanation, and control inferences. Finally, I enact an epistemic unification of causal explanation in cognitive science, according to which both mechanistic and nonmechanistic explanations of cognition can be genuine causal explanations.

This book evaluates whether or not we can decide on the best theory of concepts by appealing to the explanatory results of cognitive science. It undertakes an in-depth analysis of different theories of concepts and of the explanations formulated in cognitive science. As a result, two reasons are provided for thinking that an appeal to cognitive science cannot help to decide on the best theory of concepts.

Contemporary education is awakening from a crisis that has held the development of its potential and its relevance at bay for well over a century. Revolutions in science and spirituality are emerging a new relational intelligence that demands commensurate educational paradigms for its blossoming into daily engagements with life and the world around us. At the same time as people are leading increasingly interconnected lives, aware of and often participating in the narratives of people and ecosystems in other parts of (...) the planet, information and communications technologies are increasingly integrating with and serving to mediate the human experience. This article explores the power of this confluence at the current nexus of civilizational demands in the context of increased planetary stresses and destabilizations. The case is made for a thrivable education praxis that draws on these emergent aspects of our developmental potential and emphasizes the importance of functional conviviality as an operational principle of learning for life.

Here, I take alethic views of understanding to be all views that hold that whether an explanation is true or false matters for whether that explanation provides understanding. I then argue that there is (as yet) no naturalistic defence of alethic views of understanding in cognitive science, because there is no agreement about the correct descriptions of the content of cognitive scientific explanations. I use this claim to argue for the provisional acceptance of afactivism in cognitive science, which is the (...) view that the truth or falsity of an explanation of cognition is irrelevant to whether that explanation provides understanding. I conclude by discussing the relation between understanding in cognitive science and understanding in other domains. (shrink)

Recognized as one of the earliest Jewish neo-Platonist writers, Isaac ben Solomon Israeli influenced Muslim, Jewish, and Christian scholars through the Middle Ages. A native of Egypt who wrote in Arabic, Israeli explored definitions of such terms as imagination, sense-perception, desire, love, creation, and “coming-to-be” in his writings. This classic volume contains English translations of Israeli’s philosophical writings, including the _Book of Definitions_, the _Book of Substances,_ and the _Book on Spirit and Soul_. Additionally, _Isaac Israeli_ features a biographical sketch (...) of the philosopher and extensive notes and comments on the texts, as well as a survey and appraisal of his philosophy. Restored to print for the first time in decades, _Isaac Israeli _will be essential reading for students and scholars of medieval philosophy and Jewish studies. (shrink)

Are the real numbers rich enough to measure intelligence? We generalize a result of Alexander and Hutter about the so-called Legg-Hutter intelligence measures of reinforcement learning agents. Using the generalized result, we exhibit a paradox: in one particular version of the Legg-Hutter intelligence measure, certain agents all have intelligence 0, even though in a certain sense some of them outperform others. We show that this paradox disappears if we vary the Legg-Hutter intelligence measure to be hyperreal-valued rather than real-valued.

Cognitive theorists routinely disagree about the evidence supporting claims in cognitive science. Here, we first argue that some disagreements about evidence in cognitive science are about the evidence available to be drawn upon by cognitive theorists. Then, we show that one’s explanation of why this first kind of disagreement obtains will cohere with one’s theory of evidence. We argue that the best explanation for why cognitive theorists disagree in this way is because their evidence is what they rationally grant. Finally, (...) we explain why our view does not lead to a pernicious kind of relativism in cognitive science. (shrink)

Can an AGI create a more intelligent AGI? Under idealized assumptions, for a certain theoretical type of intelligence, our answer is: “Not without outside help”. This is a paper on the mathematical structure of AGI populations when parent AGIs create child AGIs. We argue that such populations satisfy a certain biological law. Motivated by observations of sexual reproduction in seemingly-asexual species, the Knight-Darwin Law states that it is impossible for one organism to asexually produce another, which asexually produces another, and (...) so on forever: that any sequence of organisms (each one a child of the previous) must contain occasional multi-parent organisms, or must terminate. By proving that a certain measure (arguably an intelligence measure) decreases when an idealized parent AGI single-handedly creates a child AGI, we argue that a similar Law holds for AGIs. (shrink)

Legg and Hutter, as well as subsequent authors, considered intelligent agents through the lens of interaction with reward-giving environments, attempting to assign numeric intelligence measures to such agents, with the guiding principle that a more intelligent agent should gain higher rewards from environments in some aggregate sense. In this paper, we consider a related question: rather than measure numeric intelligence of one Legg- Hutter agent, how can we compare the relative intelligence of two Legg-Hutter agents? We propose an elegant answer (...) based on the following insight: we can view Legg-Hutter agents as candidates in an election, whose voters are environments, letting each environment vote (via its rewards) which agent (if either) is more intelligent. This leads to an abstract family of comparators simple enough that we can prove some structural theorems about them. It is an open question whether these structural theorems apply to more practical intelligence measures. (shrink)

We define a notion of the intelligence level of an idealized mechanical knowing agent. This is motivated by efforts within artificial intelligence research to define real-number intelligence levels of compli- cated intelligent systems. Our agents are more idealized, which allows us to define a much simpler measure of intelligence level for them. In short, we define the intelligence level of a mechanical knowing agent to be the supremum of the computable ordinals that have codes the agent knows to be codes (...) of computable ordinals. We prove that if one agent knows certain things about another agent, then the former necessarily has a higher intelligence level than the latter. This allows our intelligence no- tion to serve as a stepping stone to obtain results which, by themselves, are not stated in terms of our intelligence notion (results of potential in- terest even to readers totally skeptical that our notion correctly captures intelligence). As an application, we argue that these results comprise evidence against the possibility of intelligence explosion (that is, the no- tion that sufficiently intelligent machines will eventually be capable of designing even more intelligent machines, which can then design even more intelligent machines, and so on).

A tension has been identified between the acquisition and participation metaphors for learning, and it is generally agreed that this tension has still not been adequately resolved. In this paper, we offer an alternative to the acquisition and participation metaphors for learning: the metaphor of mastering. Our claim is that the mastering metaphor, as grounded in inferentialism, allows one to treat both the acquisition and participation dimensions of learning as complementary and mutually constitutive. Inferentialism is a semantic theory which explains (...) concept formation in terms of the inferences individuals make in the context of an intersubjective practice of acknowledging, attributing, and challenging one another's commitments. We first introduce the key concepts of inferentialism and consider the perspective on learning that inferentialism inspires. Then, we condense the lessons of the inferentialist concepts into a single mastering metaphor for learning and argue that learning consists in the process by which learners come to master concepts and practices. We conclude by discussing how the mastering metaphor could be put to work in a theoretical reconciliation of the cognitive and sociocultural dimensions of learning. (shrink)

Can an agent's intelligence level be negative? We extend the Legg-Hutter agent-environment framework to include punishments and argue for an affirmative answer to that question. We show that if the background encodings and Universal Turing Machine (UTM) admit certain Kolmogorov complexity symmetries, then the resulting Legg-Hutter intelligence measure is symmetric about the origin. In particular, this implies reward-ignoring agents have Legg-Hutter intelligence 0 according to such UTMs.
