I argue that adaptive, self-directed misbeliefs are likely more prevalent and important than McKay & Dennett (M&D) claim. Humans often falsely interpret their own behavior in terms of culturally afforded categories. Despite their falsity, such self-interpretations are often adaptive because of our disposition to behave consistently with them. This makes us easier to interpret by similarly enculturated interactants.

The history of philosophy risks a self-opacity whereby we overestimate or underestimate our proximity to prior modes of thinking. This risk is relevant to assessing Hegel’s appropriation by McDowell and Priest. McDowell enlists Hegel for a quietist answer to the problem with assuming that concepts and reality belong to different orders, viz., how concepts are answerable to the world. If we accept Hegel’s absolute idealist view that the conceptual is boundless, this problem allegedly dissolves. Priest enlists Hegel for a dialetheist (...) answer to the problem with assuming that truth and falsity are mutually exclusive, viz., how certain sentences are both true and false. If we accept Hegel’s dialectical view that certain contradictions are necessary, this problem allegedly dissolves. For both McDowell and Priest, we find a true friend in Hegel. I argue that McDowell’s and Priest’s appropriations of Hegel overestimate Hegel’s affinity with quietism and dialetheism. McDowell reads Hegel as a quietist who silences metaphysical claims and the skeptical questions they raise against commonsense, but neglects Hegel’s adaptation of ancient skepticism against commonsense. Priest reads Hegel as a dialetheist who subordinates formal logic to dialectical logic by affirming the truth of certain contradictions, but neglects Hegel’s commitment to resolving contradictions for the sake of truth qua whole. I diagnose their misreadings in terms of what Hegel regards as the three moments of logic and argue that while McDowell jumps to its third moment, Priest stalls at its second moment. According to Hegel’s Encyclopedia Logic, logic has three “moments”: the abstractive moment of the understanding, which “stops short” at fixed categories; the negative moment of dialectic, which discovers the “genuine nature” of the categories, viz., that each “passes over, of itself, into its opposite”; and the positive moment of speculation, which grasps the “unity” of categories through the “dissolution” of their inner opposition. Hegel warns that if these moments are “kept separate from each other […] they are not considered in their truth”. I suggest that quietist and dialetheist readings of Hegel fail to consider truthfully the unified moments of his logic. In his quietist critique of metaphysics, McDowell enlists Hegel to dissolve the problem with assuming the duality of concept and reality. But McDowell helps himself directly to the third moment of logic, where the unity of the categories, and hence the boundlessness of the conceptual, would be fully articulated. Since he arrives at the third moment prematurely, ignoring its prior moments, he obscures its truth (§1). In his dialetheist critique of formal logic, Priest enlists Hegel to dissolve the problem with assuming the duality of truth and falsity. But Priest restricts himself gratuitously to the second moment of logic, where contradictions within the categories are not yet resolved. Since he stalls at the second moment, severed from its final moment, he obscures its truth (§2). I argue we can extricate Hegel from quietist and dialetheist misreadings only if we grasp the truth of the three moments of logic. (shrink)

The viewpoint of Evolutionary Epistemology (EE) and of Genetic Epistemology (GE) on classical epistemological questions is strikingly different: EE starts with Evolutionary Biology, the subject of which is population's dynamics. GE, however, starts with Developmental Psychology and thus focusses the development of individuals. By EE knowledge is seen as portraying or copying process, and truth is interpreted as a product of adaptation, whereas for GE knowledge is due to a construction process in which the production of true insights is only (...) one possibility among others: Like falsity, error and deception, true knowledge goes back to a free relationship to reality. The difference between scientific and common knowledge is hard to be checked by EE, since both result ultimately from human hereditary structures. The study of how scientific knowledge emerges from everyday cognition is rather the task of GE. (shrink)

Statements about fictional characters, such as “Gregor Samsa has been changed into a beetle,” pose the problem of how we can say something true (or false) using empty names. I propose an original solution to this problem that construes such utterances as reports of the “prescriptions to imagine” generated by works of fiction. In particular, I argue that we should construe these utterances as specifying, not what we are supposed to imagine—the propositional object of the imagining—but how we are supposed (...) to imagine. Most other theories of thought and discourse about fictional characters either fail to capture the intentionality of our imaginings, or else obscure the differences between imaginings directed toward fictional characters and those directed toward real individuals. I argue that once we have an account of prescriptions to imagine about real individuals, we can adapt the same framework to specify the contents of prescriptions to imagine about fictional characters, and thereby to account for the truth (or falsity) of statements about fictional characters.

In this paper we critically review Correia’s and Rosenkranz’s Nothing to Come. A Defence of the Growing Block Theory of Time, published by Springer in 2018. By taking into account the essential reliance of the book on tense logic, we bring out the existence of a conflict between their logical axioms, that presuppose truth bivalence even for statements concerning future contingents, and the principle of groundedness that they also advocate. According to this principle, a proposition Q is now groundedly true (...) as long as sometimes in the future it will be the case that there exists something that makes Q true. However, if the events that occur in 2060 do not exist unrestrictedly (for us, here in 2021), what, in reality, can possibly ground the truth (or falsity) of Q? In the second part of the paper, we concentrate on some conceptual difficulties raised by their brilliant attempt to adapt the growing block view of reality to a relativistic setting, based on what they call bow-tie presentism, according to which for each spacetime point s only s plus the spacelike-related region with respect to s exists. By extending temporal logic into a relativity-friendly spatiotemporal logic, we conclude by noting that Correia and Rosenkranz’s Nothing to Come makes very important strides in showing that there are technical ways to develop the growing block of reality into an ontology that coheres with relativity theories perfectly well, while retaining most of the distinctive content of classical growing block theory.

The canonical arguments against the description theory of names are usually taken to have established that the reference of a name as used on a given occasion is not semantically determined by the qualitative descriptions that the speaker may have in mind. The deepest moral of these arguments, on the received view, would be that the speaker’s narrow mental states play no semantic role in fixing reference. My central aim in this paper is to challenge this common understanding by highlighting (...) that the same argumentative schemas can be adapted to undermine a related non-description theory, according to which the reference of a name as used on a given occasion would semantically depend on broad mental states of the speaker. Once this is realised, it becomes evident that the falsity of the description theory is not the deepest lesson of the canonical arguments, but only a consequence of the deepest lesson. The most fundamental moral is that the speaker’s mental states, whether narrow or broad, do not always determine linguistic reference. (shrink)

Assuming that the target of theory oriented empirical science in general and of nomic truth approximation in particular is to characterize the boundary or demarcation between nomic possibilities and nomic impossibilities, I have presented, in my article entitled “Models, postulates, and generalized nomic truth approximation” :3057–3077, 2016. 10.1007/s11229-015-0916-9), the ‘basic’ version of generalized nomic truth approximation, starting from ‘two-sided’ theories. Its main claim is that nomic truth approximation can perfectly be achieved by combining two prima facie opposing views on theories: (...) the traditional view: theories are postulates that exclude certain possibilities from being realizable, enabling explanation and prediction and the model view: theories are sets of models that claim to represent certain realizable possibilities. Nomic truth approximation, i.e. increasing truth-content and decreasing falsity-content, becomes in this way revising theories by revising their models and/or their postulates in the face of increasing evidence. The basic version of generalized nomic truth approximation is in many respects as simple as possible. Among other things, it does not take into account that one conceptual possibility may be more similar to another than a third one. However, for example, one theory may include a possibility that is more similar to a wrongly not included possibility than another theory can offer. Similarly, for wrongly not excluded possibilities. In this article it will be shown that such ‘refined’ considerations can be taken into account by adapted clauses based on a ternary similarity relation between possibilities. This allows again abductive conclusions about refined truth approximation if a theory is persistently more successful in the refined sense than another. It will also be indicated and illustrated that this refined approach enables a specification to the effect that refined truth approximation can be obtained by the method of idealization and subsequent concretization. Finally, the basic and the refined approach will be evaluated with regard to some general principles and objections that have been discussed in the literature. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.2 (2002) 131-136 [Access article in PDF] Language, Logic, and Recovery:A Commentary on van Staden Paul Falzer and Larry Davidson Keywords: analytic philosophy, experience, Frege, ordinary language, psychosis, psychotherapy. VAN STADEN'S PAPER, "Linguistic Markers of Recovery," takes on a formidable task. As he explains it, findings from a previously conducted empirical study suggest that recovery from a psychiatric condition can be predicted by certain patterns (...) of first person pronoun usage. His current paper explains how these patterns follow the mathematical logic of Gottlob Frege. van Staden's attempt to systematize the link between language and treatment outcome shows promise. We want to support his effort by raising a few caveats about the application of foundational systems in psychiatry and psychology, particularly the advisability of employing a logical system to explain recovery from mental illness. Along the way, we will be identifying related issues that the author may elect to take up in his future work.van Staden's proposal is inspired by Frege's logical system, but the paper is, at the very least, an innovative adaptation. There are various points where we are left to wonder just how much of this proposal is really Frege's. Nevertheless, the genesis of van Staden's ideas is so dependent that one would expect a fuller account of Frege's pivotal role in the development of modern logic, how his work precipitated what is known commonly as the linguistic turn, and why a logical system that was so well received when first articulated was eclipsed so quickly by Russell's Principia (1963) and Wittgenstein's Tractatus. (1981) These issues can be addressed separately and perhaps they should, because lacking an account of how Frege's philosophy developed and evolved makes the presentation appear somewhat sketchy and incomplete.Frege is portrayed in philosophical lore as the founder of modern logic and a pioneer of the movement that later became known as analytic philosophy. Dummett (1991) regards Frege's Foundations of Arithmetic (1968) as analytical philosophy's first work (p. 111). According to Quine (1955), "All modern logic owes an incalculable debt to Frege. If anyone can be singled out as the founder of mathematical logic, it is by all odds he" (p. 158). Rorty (1967) notes that analytic philosophy's tack of construing philosophical questions as turning on language use and construction challenges the entire tradition, from Parmenides forward. However, the challenge reaches fruition not in Frege, but in works of Moore, Wittgenstein, and Austin. Rather than [End Page 131] sharing the limelight with the great analytic philosophers, Frege has become somewhat of a peripheral figure, whose contribution is usually portrayed as transitional. In some respects, analytic philosophy was moving against Frege's, and later, Russell's logical systems as it was concomitantly countering the various strands of idealism expounded principally by Bradley and McTaggart (see Hacker 1996, 5-12). Almost from the outset, Fregean logic was caught in a cross fire, and the author is obligated to tell us why we should be attending to the pristine version and not the more fully developed approaches that came soon after.Such a justification undoubtedly would begin with the dictum most central to Frege's philosophical thought, that propositions are primary. For Kemp (1998), this declaration carries two interrelated implications: Logical propositions are the real bearers of truth and falsity, and reasoning is a movement from one judgment to another (see p. 218). Frege posits that propositions are independent of mind, grammar, and language use. Knowledge and cognition are embodied in, but do not predicate, judgment. Frege adamantly rejects the notion that philosophical concepts are grounded in psychological phenomena, such as perception, sense impression, and some traditional accounts of meaning. This is the doctrine known as psychologism, and Frege abjures the suggestion that psychology can contain the sciences or adjudicate their findings (Frege 1956; for a discussion of this doctrine, see Notturno 1989; Davidson 1988; Davidson and Cosgrove 1991). The dictum that propositions are primary dispels the commonly held idea that reasoning begins with perception and proceeds... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Representation and the Mind-Body Problem in Spinoza by Michael Della RoccaWilliam SackstederMichael Della Rocca. Representation and the Mind-Body Problem in Spinoza. New York: Oxford University Press, 1996. Pp xiv + 223. Cloth, $39.95.A first virtue in elucidating any great philosopher is stating exactly the project the commentator undertakes, showing what is to be concluded, and how, and what of necessity must be omitted. Here, Della Rocca’s success is (...) exemplary.I cannot do better than to paraphrase, with running quotations, his remarkably succinct preliminaries. He undertakes two problems “crucial to Spinoza’s philosophy of mind,” first, “the requirement for having a thought about a particular object,” and second, “the traditional problem of whether or not the mind is identical with the body.” These inquiries are to be interconnected systematically by showing their dependence on Spinoza’s “denial of causal or explanatory or conceptual relations between the mental and the physical.”With exceptions I note later, the nine chapters of this book follow precisely. Chapter 1 prepares basic concepts and claims, along with formulation of the principle indicated, now called “the barrier between thought and extension.” Chapters 2 through 5 present and question Spinoza’s “theory of representation” (the first problem, as in the title) with its consequences respecting the announced principle. Chapters 7 and 8 turn to insights on “the mind-body problem” (the second problem), as illuminated by these investigations and secured by the governing principle. Della Rocca tidily exemplifies ruling expository virtues, but I question whether this very exactitude does not inhibit a needed species of escapement. Any commentator is obliged to acknowledge and detach himself from his own assumptions, from mannerisms and jargon current in the profession, from his present status or mannered tics, and from accidental skewing subsequent to current practices of language and translation. For such commitments also govern his treatment and they may often occlude his or our understanding. Let me be picky in initial illustration. [End Page 136]On pages 25f., the author correctly warns about pitfalls occasioned by lack of articles, definite or indefinite, in Latin. Thus, as he is aware, both interpretation and translation are queasy and infected with responses and glosses insinuated by demands from our own language, especially our prevailing fondness for definite articles, for solidity, univocal designation, and instantiation. So far, so good. But I invite my readers here to reflect whether Della Rocca’s own pervasive use of the definite article in the quotations I indulged in surveying his task does not distort his whole conception of that project. Momentum from the word the converts issues and verbalisms entertained into furniture of the world.Perhaps even more insidiously, Della Rocca invokes a peculiar itemization whereby recent formulations impose “at least one” and “for any x” on all quantified inferential usages. Moderns need rather liberation from membership suggestions in set theory and its associated logic. His remarks about “extension” and “intension” help, but they do not remedy modernist ineptness regarding Spinoza’s use of ipse, per se, and in se. Further, like precision obscures care about subordinate and causal differentiations. A sort of subsumed merging under a unit whole simple in nature is dear to Spinoza, though such moves are uncongenial to us.My earlier account scanted chapters 6 and 9, which also follow from the basic project, though not as tidily. Chapter 6, “Falsity,” “solves certain thorny problems” in the account of that and its opposite; Chapter 9 gathers ruling materials to shed light on “substantive monism.” Their arrangement ought to assist our perplexities about involvement and simple grasp, whereas 6 is noticeably brief and 9 sketchy. Together, they scant (rather than illuminate) subtlety in Spinoza’s investigations of intellect and its involvment in the nature of things.Expository clarity also shows in current fashions for multiple cross-references between indented and numbered claims, paraphrases, inferential premisses, and glosses by others. But beyond hiding preference for propositional reductions, and beyond hindering smooth reflection, such dismemberment prejudices against modes of reasoning tracing “some certain sort of eternity” or “what is common to all and equally in part and whole.”Efforts to work rigorously with made-up words or adapted phrases only...

Charles Peirce incorporates modality into his Existential Graphs by introducing the broken cut for possible falsity. Although it can be adapted to various modern modal logics, Zeman demonstrates that making no other changes results in a version that he calls Gamma-MR, an implementation of Jan Łukasiewicz's four-valued Ł-modal system. It disallows the assertion of necessity, reflecting a denial of determinism, and has theorems involving possibility that seem counterintuitive at first glance. However, the latter is a misconception that arises from (...) overlooking the distinction between the intermediate truth values that are assigned to possibly true propositions as either X-contingent or Y-contingent. Any two propositions having the same ITV are possible together, while any two propositions having different ITVs, including those that are each other's negation, are possible individually yet not possible together. Porte shows that Ł-modal can be translated into classical logic by defining a constant for each ITV such that its implication of another proposition asserts the latter's possibility, while its conjunction with another proposition asserts the latter's necessity. These are expressed in the Alpha part of EG without broken cuts, simplifying derivations and shedding further light on Łukasiewicz's system, as long as graphs including either of the constants are properly interpreted. Ł-modal and Gamma-MR thus capture the two-sided nature of possibility as the limit between truth and falsity in Peirce's triadic conception. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 25.2 (2001) 251-277 [Access article in PDF] Hans Christian Andersen's Fish Out of Water Nancy Easterlin I Now that Darwinian literary criticism is on the horizon, the natural human tendency to codify manifests itself in calls to summarize succinctly what such an approach entails. Though clarity is always to be praised, bioevolutionary critics need to guard against the reductiveness that has beleaguered attempts at a scientifically (...) grounded literary criticism since the early twentieth century; most especially, we should think twice about limiting the interpretation of complex and varied works to selected sociobiological themes divorced from other biocultural considerations. David Sloan Wilson makes much the same point to students of evolution when he quotes Celia Heyes in a recent review of Evolutionary Psychology, David Buss's new textbook: "When I first encountered the term 'evolutionary psychology,' I thought it referred to the study of how mind and behavior evolved. But I was mistaken. In current usage, 'evolutionary psychology' refers exclusively to research on human mentality and behavior, motivated by a very specific, nativist-adaptationist interpretation of how evolution operates." 1If, as D. S. Wilson suggests, evolutionary psychology thus narrowly defined threatens to produce a limited understanding of human mind and behavior and, in the process, fragment the discipline of psychology further, how much less potentially productive is such an approach for those of us whose central objects of study, cultural artifacts, are as the products of behavior even further removed from the study of mind? Leda Cosmides and John Tooby are most explicit about the falsity of assuming that psychological adaptations determine behavior. This being so, it seems impossible that such adaptations could determine the [End Page 251] meaning of artworks, which are themselves the products of complex human behaviors. As I hope this discussion of Hans Christian Andersen's "Little Mermaid" will demonstrate, an approach to aesthetics strictly following the lead of evolutionary psychology as currently defined, while supplying valuable general insights about the motives for artistic behaviors and the cognitive processes engaged in them, cannot by itself inform us about the meaning of individual artworks. This is a crucial issue, since interpretation is the fundamental pursuit of scholars in fields like mine, literary studies.Putting the question of interpretive frutifulness aside for the moment, it can be said unequivocally that criticism that fails to be sensitive to mutation and change is not properly Darwinian. Evolutionary psychology and sociobiology themselves maintain that our psychic architecture is comprised of domain-specific competences; the result, as E. O. Wilson points out, is that the human mind is not designed to understand reality but is instead an instrument for survival and reproduction. 2 "Natural selection," says Michael Ruse, "works in a gerry-building fashion, making do with what it has at hand." 3 Though our various evolved competences cannot be radically dissonant if the organism is to survive, neither are they logically integrated, neatly interlocking "modules." Under some environmental conditions, specific adaptations or epigenetic rules are not likely to produce a competitive advantage while other very different adaptations certainly will, and hence the flexibility of the organism ensures its survival. If, for instance, I place my coffee mug down on my desk and at that exact moment two cars collide on the street outside, familiarity with my environment militates against invocation of the causal rule, even though such a rule is incontrovertibly part of our adapted psychology. 4 Knowing, then, that we share an evolved psychic architecture whose patient excavation, so to speak, will result in a progressively better defined concept of human nature, and knowing too that the behavior of human beings as writers as well as other kinds of agents varies under divergent environmental conditions, Darwinian criticism should be sensitive to the complex relationship between individual adaptations, the total array of adaptations, subjective cognitive processes, and environmental circumstances that give literary works enduring significance. In contemplating literary meaning, as with aesthetics, we should be mindful that epigenesis is not simply the instantiation of epigenetic rules. 5 Ideally, literary interpretation should be informed by the evolution of mind, behavior, and...

The visual system adapts to a wide range of visual features, from lower-level features like color and motion to higher-level features like causality and, perhaps, number. According to some, adaptation is a strictly perceptual phenomenon, such that the presence of adaptation licenses the claim that a feature is truly perceptual in nature. Given the theoretical importance of claims about adaptation, then, it is important to understand exactly when the visual system does and does not exhibit adaptation. Here, we take as (...) a case study one specific kind of adaptation: visual adaptation to size. Supported by evidence from four experiments, we argue that, despite robust effects of size adaptation in the lab, (1) size adaptation effects are phenomenologically underwhelming (in some cases, hardly appreciable at all), (2) some effects of size adaptation appear contradictory, and difficult to explain given current theories of size adaptation, and (3) prior studies on size adaptation may have failed to isolate size as the adapted dimension. Ultimately, we argue that while there is evidence to license the claim that size adaptation is genuine, size adaptation is a puzzling and poorly understood phenomenon. (shrink)

Although there is a massive amount of work on truth, there is very little work on falsity. Most philosophers probably think this is appropriate; after all, once we have a solid understanding of truth, falsity should not prove to be much of a challenge. However, there are several interesting and difficult issues associated with understanding falsity. After considering two prominent definitions of falsity and presenting objections to each one, I propose a definition that avoids their problems.

This paper synthesizes convergent lines of evidence to evaluate the hypothesis that objective falsity is essential to lying. Objective accounts of lying affirm this hypothesis; subjective accounts deny it. Evidence from history, logic, social observation, popular culture, lexicography, developmental psychology, inference, spontaneous description, and behavioral experimentation strongly supports the hypothesis. Studies show that the only apparent evidence against the hypothesis is due to task substitution, i.e. ethical concerns or perspective-taking interfering with performance on categorization tasks. I conclude that, overall, (...) existing evidence decisively favors objective accounts. (shrink)

This book argues that the meaning of negation, perhaps the most important logical constant, cannot be defined within the framework of the most comprehensive theory of proof-theoretic semantics, as formulated in the influential work of Michael Dummett and Dag Prawitz. Nils Kürbis examines three approaches that have attempted to solve the problem - defining negation in terms of metaphysical incompatibility; treating negation as an undefinable primitive; and defining negation in terms of a speech act of denial - and concludes that (...) they cannot adequately do so. He argues that whereas proof-theoretic semantics usually only appeals to a notion of truth, it also needs to appeal to a notion of falsity, and proposes a system of natural deduction in which both are incorporated. Offering new perspectives on negation, denial and falsity, his book will be important for readers working on logic, metaphysics and the philosophy of language. (shrink)

It is often assumed that adaptation — a temporary change in sensitivity to a perceptual dimension following exposure to that dimension — is a litmus test for what is and is not a “primary visual attribute”. Thus, papers purporting to find evidence of number adaptation motivate a claim of great philosophical significance: That number is something that can be seen in much the way that canonical visual features, like color, contrast, size, and speed, can. Fifteen years after its reported discovery, (...) number adaptation’s existence seems to be nearly undisputed, with dozens of papers documenting support for the phenomenon. The aim of this paper is to offer a counterweight — to critically assess the evidence for and against number adaptation. After surveying the many reasons for thinking that number adaptation exists, we introduce several lesser-known reasons to be skeptical. We then advance an alternative account — the old news hypothesis — which can accommodate previously published findings while explaining various (otherwise unexplained) anomalies in the existing literature. Next, we describe the results of eight pre-registered experiments which pit our novel old news hypothesis against the received number adaptation hypothesis. Collectively, the results of these experiments undermine the number adaptation hypothesis on several fronts, whilst consistently supporting the old news hypothesis. More broadly our work raises questions about the status of adaptation itself as a means of discerning what is and is not a visual attribute. (shrink)

According to the principle of bivalence, truth and falsity are jointly exhaustive and mutually exclusive options for a statement. It is either true or false, and not both, even in a borderline case. That highly controversial claim is central to the epistemic theory of vagueness, which holds that borderline cases are distinguished by a special kind of obstacle to knowing the truth-value of the statement. But this paper is not a defence of the epistemic theory. If bivalence holds, it (...) presumably does so as a consequence of what truth and falsity separately are. One may therefore expect bivalence to be derivable from a combination of some principles characterizing truth and other principles characterizing falsity. Indeed, such derivations are easily found. Their form will of course depend on the initial characterizations of truth and falsity, and not all such characterizations will permit bivalence to be derived. In this paper we focus on the relation between its derivability and some principles about truth and falsity. We will use borderline cases for vague expressions as primary examples of an urgent..

Was human nature designed by natural selection in the Pleistocene epoch? The dominant view in evolutionary psychology holds that it was -- that our psychological adaptations were designed tens of thousands of years ago to solve problems faced by our hunter-gatherer ancestors. In this provocative and lively book, David Buller examines in detail the major claims of evolutionary psychology -- the paradigm popularized by Steven Pinker in The Blank Slate and by David Buss in The Evolution of Desire -- and (...) rejects them all. This does not mean that we cannot apply evolutionary theory to human psychology, says Buller, but that the conventional wisdom in evolutionary psychology is misguided.Evolutionary psychology employs a kind of reverse engineering to explain the evolved design of the mind, figuring out the adaptive problems our ancestors faced and then inferring the psychological adaptations that evolved to solve them. In the carefully argued central chapters of Adapting Minds, Buller scrutinizes several of evolutionary psychology's most highly publicized "discoveries," including "discriminative parental solicitude". Drawing on a wide range of empirical research, including his own large-scale study of child abuse, he shows that none is actually supported by the evidence.Buller argues that our minds are not adapted to the Pleistocene, but, like the immune system, are continually adapting, over both evolutionary time and individual lifetimes. We must move beyond the reigning orthodoxy of evolutionary psychology to reach an accurate understanding of how human psychology is influenced by evolution. When we do, Buller claims, we will abandon not only the quest for human nature but the very idea of human nature itself. (shrink)

Contemporary biological research has suggested that some host–microbiome multispecies systems (referred to as “holobionts”) can in certain circumstances evolve as unique biological individual, thus being a unit of selection in evolution. If this is so, then it is arguably the case that some biological adaptations have evolved at the level of the multispecies system, what we call hologenomic adaptations. However, no research has yet been devoted to investigating their nature, or how these adaptations can be distinguished from adaptations at the (...) species-level (genomic adaptations). In this paper, we cover this gap by investigating the nature of hologenomic adaptations. By drawing on the case of the evolution of sanguivory diet in vampire bats, we argue that a trait constitutes a hologenomic adaptation when its evolution can only be explained if the holobiont is considered the biological individual that manifests this adaptation, while the bacterial taxa that bear the trait are only opportunistic beneficiaries of it. We then use the philosophical notions of emergence and inter-identity to explain the nature of this form of individuality and argue why it is special of holobionts. Overall, our paper illustrates how the use of philosophical concepts can illuminate scientific discussions, in the trend of what has recently been called metaphysics of biology. (shrink)

In Metaphysics Delta 29 Aristotle distinguishes three classes of falsity and three corresponding senses of the ‘false’. The paper examines Aristotle’s arguments from a close-reading perspective, and analyses the meaning of false ‘as a thing’ , the significance of Aristotle’s dispute with Antisthenes on the subject of contradiction and verbal falsehood, and Aristotle’s conception of the false person. By paying attention to the precise order of Aristotle’s presentation, the paper raises the question about the manner in which the three (...) classes of falsity are related to one another and provides a tentative answer that could explain why the ‘false’ is included in the philosophical dictionary of the Metaphysics. On the proposed interpretation, Aristotle assumes that a fundamental difference operates in all cases of falsity , and that this difference is the outcome of the ontological determinacy of substance. Keywords: Aristotle; Metaphysics; falsity; factual falsity; propositional falsity; ethical falsity; Antisthenes; contradiction; substance; ontology; logic. (shrink)

It is widely held that there are important differences between indicative conditionals (e.g. “If the authors are linguists, they have written a linguistics paper”) and subjunctive conditionals (e.g. “If the authors had been linguists, they would have written a linguistics paper”). A central difference is that indicatives and subjunctives convey different stances towards the truth of their antecedents. Indicatives (often) convey neutrality: for example, about whether the authors in question are linguists. Subjunctives (often) convey the falsity of the antecedent: (...) for example, that the authors in question are not linguists. This paper tests prominent accounts of how these different stances are conveyed: whether by presupposition or conversational implicature. Experiment 1 tests the presupposition account by investigating whether the stances project – remain constant – when embedded under operators like negations, possibility modals, and interrogatives, a key characteristic of presuppositions. Experiment 2 tests the conversational-implicature account by investigating whether the stances can be cancelled without producing a contradiction, a key characteristic of implicatures. The results provide evidence that both stances – neutrality about the antecedent in indicatives and the falsity of the antecedent in subjunctives – are conveyed by conversational implicatures.

I argue, first, that the deprived individuals whose predicaments Nussbaum cites as examples of "adaptive preference" do not in fact prefer the conditions of their lives to what we should regard as more desirable alternatives, indeed that we believe they are badly off precisely because they are not living the lives they would prefer to live if they had other options and were aware of them. Secondly, I argue that even where individuals in deprived circumstances acquire tastes for conditions (...) that we regard as bad, they are typically better off having their acquired preferences satisfied. If they are badly off it is because they cannot get what we and they, would regard as more desirable alternatives. Preference utilitarianism explains why individuals in such circumstances are badly off whether they have adapted to their deprived circumstances or not. Even if they prefer the conditions of their lives to all other available alternatives, most would prefer alternatives that are not available to them which would, on the preferentist account, make them better off. And that, on the preferentist account, is the basis for a radical critique of unjust institutions that limit people's options and prevent them from getting what they want. (shrink)

Khader offers a deliberative perfectionist approach to identifying and responding to adaptive preferences-- deprived people's preferences that perpetuate their deprivation.
