Algebraic Art explores the invention of a peculiarly Victorian account of the nature and value of aesthetic form, and it traces that account to a surprising source: mathematics. Drawing on literature, art, and photography, it explores how the Victorian mathematical conception of form still resonates today.

As familiar as the form of the mathematical equation is to us, the ostensibly simple act of equating unlike things was an achievement many centuries in the making, and one that would ultimately redefine European mathematical enquiry such that its bias toward geometry and the concrete would be displaced by a bias toward algebraic abstraction. The moment of that displacement was the nineteenth century, and its broader significance is on particularly striking display in the British context, where the implications of (...) algebraic abstraction were the object of sustained enquiry among mathematicians, logicians, and economists. This article argues that the ascendance of the algebraic equation, and the transformation in the conception of number on which it was premised, were not simply the product of evolutionary pressures internal to mathematics; the Victorian embrace of algebra was also a response to the practical and cognitive demands of Victorian economic life, which was increasingly reliant on attenuated exchange relations and merely nominal forms of ownership. This was an economy organized around the global extension of trade and characterized by the exponential growth of financial intermediation, of what Walter Bagehot called “number abstracted from reference.” Victorian economic practices thus modeled an abstraction that helped to justify the abstractions of mathematics, and that mathematics in turn was used by economic theorists to argue for the necessity and objectivity of their models. This mutually sustaining dialogue is particularly visible in the writings of William Stanley Jevons, who applied the principles of algebra to philosophy and economic theory so as to reconceive the logic of cognitive and social life in terms of equations. This logic, for which he was merely a spokesman, continues to shape our faith in the special value of abstract, theoretical knowledge. (shrink)

"How can human beings, who are liable to error, possess knowledge, since the grounds on which we believe do not rule out that we are wrong? Andrea Kern argues that we can disarm this skeptical doubt by conceiving knowledge as an act of a rational capacity. In this book, she develops a metaphysics of the mind as existing through knowledge of itself."--Provided by publisher.

Name any valued human trait—intelligence, wit, charm, grace, strength—and you will find an inexhaustible variety and complexity in its expression among individuals. Yet we insist that such diversity does not provide grounds for differential treatment at the most basic level. Whatever merit, blame, praise, love, or hate we receive as beings with a particular past and a particular constitution, we are always and everywhere due equal respect merely as persons. -/- But why? Most who attempt to answer this question appeal (...) to the idea that all human beings possess an intrinsic dignity and worth—grounded in our capacities, for example, to reason, reflect, or love—that raises us up in the order of nature. Andrea Sangiovanni rejects this predominant view and offers a radical alternative. -/- To understand our commitment to basic equality, Humanity without Dignity argues that we must begin with a consideration not of equality but of inequality. Rather than search for a chimerical value-bestowing capacity possessed to an equal extent by each one of us, we ought to ask: Why and when is it wrong to treat others as inferior? Sangiovanni comes to the conclusion that our commitment to moral equality is best explained by a rejection of cruelty rather than a celebration of rational capacity. He traces the impact of this fundamental shift for our understanding of human rights and the norms of anti-discrimination that underlie it. (shrink)

This paper explores an idea of Stoic descent that is largely neglected nowadays, the idea that an argument is valid when the conditional formed by the conjunction of its premises as antecedent and its conclusion as consequent is true. As it will be argued, once some basic features of our naıve understanding of validity are properly spelled out, and a suitable account of conditionals is adopted, the equivalence between valid arguments and true conditionals makes perfect sense. The account of validity (...) outlined here, which displays one coherent way to articulate the Stoic intuition, accords with standard formal treatments of deductive validity and encompasses an independently grounded characterization of inductive validity.

Citizen science models of public participation in scientific research represent a growing area of opportunity for health and biomedical research, as well as new impetus for more collaborative forms of engagement in large-scale research. However, this also surfaces a variety of ethical issues that both fall outside of and build upon the standard human subjects concerns in bioethics. This article provides background on citizen science, examples of current projects in the field, and discussion of established and emerging ethical issues for (...) citizen science in health and biomedical research.

.This paper discusses Aristotle’s thesis and Boethius’ thesis, the most distinctive theorems of connexive logic. Its aim is to show that, although there is something plausible in Aristotle’s thesis and Boethius’ thesis, the intuitions that may be invoked to motivate them are consistent with any account of indicative conditionals that validates a suitably restricted version of them. In particular, these intuitions are consistent with the view that indicative conditionals are adequately formalized as strict conditionals.

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

Andrea Falcon's work is guided by the exegetical ideal of recreating the mind of Aristotle and his distinctive conception of the theoretical enterprise. In this concise exploration of the significance of the celestial world for Aristotle's science of nature, Falcon investigates the source of discontinuity between celestial and sublunary natures and argues that the conviction that the natural world exhibits unity without uniformity is the ultimate reason for Aristotle's claim that the heavens are made of a special body, unique (...) to them. This book presents Aristotle as a totally engaged, systematic investigator whose ultimate concern was to integrate his distinct investigations into a coherent interpretation of the world we live in, all the while mindful of human limitations to what can be known. Falcon reads in Aristotle the ambition of an extraordinarily curious mind and the confidence that that ambition has been largely fulfilled. (shrink)

Business Ethics: A European Review, EarlyView.

This paper articulates in formal terms a crucial distinction concerning future contingents, the distinction between what is true about the future and what is reasonable to believe about the future. Its key idea is that the branching structures that have been used so far to model truth can be employed to define an epistemic property, credibility, which we take to be closely related to knowledge and assertibility, and which is ultimately reducible to probability. As a result, two kinds of claims (...) about future contingents—one concerning truth, the other concerning credibility—can be smoothly handled within a single semantic framework. (shrink)

This paper addresses the question whether future contingents are knowable, that is, whether one can know that things will go a certain way even though it is possible that things will not go that way. First I will consider a long-established view that implies a negative answer, and draw attention to some endemic problems that affect its credibility. Then I will sketch an alternative line of thought that prompts a positive answer: future contingents are knowable, although our epistemic access of (...) them is limited in some important respects.

Organoids are three-dimensional biological structures grown in vitro from different kinds of stem cells that self-organise mimicking real organs with organ-specific cell types. Recently, researchers have managed to produce human organoids which have structural and functional properties very similar to those of different organs, such as the retina, the intestines, the kidneys, the pancreas, the liver and the inner ear. Organoids are considered a great resource for biomedical research, as they allow for a detailed study of the development and pathologies (...) of human cells; they also make it possible to test new molecules on human tissue. Furthermore, organoids have helped research take a step forward in the field of personalised medicine and transplants. However, some ethical issues have arisen concerning the origin of the cells that are used to produce organoids and their properties. In particular, there are new, relevant and so-far overlooked ethical questions concerning cerebral organoids. Scientists have created so-called mini-brains as developed as a few-months-old fetus, albeit smaller and with many structural and functional differences. However, cerebral organoids exhibit neural connections and electrical activity, raising the question whether they are or will one day be somewhat sentient. In principle, this can be measured with some techniques that are already available, which are used for brain-injured non-communicating patients. If brain organoids were to show a glimpse of sensibility, an ethical discussion on their use in clinical research and practice would be necessary. (shrink)

There are essentially two ways to develop the Peircean idea that future contingents are all false. One is to provide a quantificational semantics for "will," as is usually done. The other is to define a quantificational postsemantics based on a linear semantics for "will." As we will suggest, the second option, although less conventional, is more plausible than the first in some crucial respects. The postsemantic approach overcomes three major troubles that have been raised in connection with Peirceanism: the apparent (...) scopelessness of "will" with respect to negation, the failure of Future Excluded Middle, and the so-called zero credence problem.

It has been repeatedly stated that approach and avoidance reactions to emotional faces are triggered by the intention signalled by the emotion. This line of thought suggests that each emotion signals a specific intention triggering a specific behavioural reaction. However, empirical results examining this assumption are inconsistent, suggesting that it might be too short-sighted. We hypothesise that the same emotional expression can signal different social messages and, therefore, trigger different reactions; which social message is signalled by an emotional expression should (...) be influenced by moderating variables, such as the group membership of the expresser. In two experiments, we show that group membership influences approach and avoidance reactions to emotional expressions: Emotions (fear and happiness) expressed by in-group members elicited concordant behaviour, whereas emotions expressed by out-group members activated the reverse pattern. A third experiment, in which participants directly evaluated smiling and fearful individuals resembling in-group and out-group members supported this result. (shrink)

An influential tradition holds that thoughts are public: different thinkers share many of their thoughts, and the same applies to a single subject at different times. This ‘publicity principle’ has recently come under attack. Arguments by Mark Crimmins, Richard Heck and Brian Loar seem to show that publicity is inconsistent with the widely accepted principle that someone who is ignorant or mistaken about certain identity facts will have distinct thoughts about the relevant object—for instance, the astronomer who does not know (...) that Hesperus is Phosphorus will have two distinct thoughts Hesperus is bright and Phosphorus is bright. In this paper, I argue that publicity can be defended if we adopt a relational account on which thoughts are individuated by their mutual relations. I then go on to develop a specific relational theory—the ‘linking account’—and contrast it with other relational views. (shrink)

My goal in this paper is to discuss the 'Fregean' account of inferences proposed by Recanati in his 'Mental Files' (Oxford University Press, 2012). I raise the following dilemma for the mental files theory. (a) If the premises of certain inferences involve 'the same file' in a strict sense of the expression, then files cannot play the role of modes of presentation. (b) If, on the other hand, the files involved in the premises are 'the same' only in a loose (...) sense, then the notion of file sameness plays no role in accounting for rational inferences, contra Recanati's Fregean account.

In this article, I provide a historical and bibliographical exploration of the handwritten, dictated commentaries (dictata) of Johannes de Raey (1620/1622–1702) on the texts of René Descartes (1596–1650), shedding light on their structure, development, and on their relations with the academic commentaries of Johannes Clauberg (1622–1665) and Christoph Wittich (1625–1687). The study of these commentaries, which are extant as class notes, is important because they conveyed one of the first systematic teachings of Descartes’s ideas and constituted a vehicle for their (...) further dissemination across northern Europe.

Human cerebral organoids (HCOs) are three-dimensional in vitro cell cultures that mimic the developmental process and organization of the developing human brain. In just a few years this technique has produced brain models that are already being used to study diseases of the nervous system and to test treatments and drugs. Currently, HCOs consist of tens of millions of cells and have a size of a few millimeters. The greatest limitation to further development is due to their lack of vascularization. (...) However, recent research has shown that human cerebral organoids can manifest the same electrical activity and connections between brain neurons and EEG patterns as those recorded in preterm babies. All this suggests that, in the future, HCOs may manifest an ability to experience basic sensations such as pain, therefore manifesting sentience, or even rudimentary forms of consciousness. This calls for consideration of whether cerebral organoids should be given a moral status and what limitations should be introduced to regulate research. In this article I focus particularly on the study of the emergence and mechanisms of human consciousness, i.e. one of the most complex scientific problems there are, by means of experiments on HCOs. This type of experiment raises relevant ethical issues and, as I will argue, should probably not be considered morally acceptable. (shrink)

In this article I argue that new light can be shed on the analytic/Continental divide by looking at the controversy on the nature of philosophy in late 19th-century/early-20th-century Germany. The controversy is between those thinkers who understand philosophy primarily as a worldview [ Weltanschauung] and those who insist that it should be understood as a science [ Wissenschaft]. The positions of the two main representatives of the two camps, Wilhelm Dilthey and Heinrich Rickert, are presented and assessed. Their mutual disagreement (...) on what philosophy ought to be reflects in a striking way some of the major tensions existing between the analytic and the Continental camps today. At the end of the article I formulate a historical hypothesis about how the Wissenschaft/Weltanschauung controversy petrified into the analytic/Continental divide. (shrink)

A long-standing puzzle for moral philosophers and psychologists alike is the concept of psychopathy, a personality disorder marked by tendencies to defy moral norms despite cognitive knowledge about right and wrong. Previously, discussions of the moral deficits of psychopathy have focused on willingness to harm and cheat others as well as reasoning about rule-based transgressions. Yet recent research in moral psychology has begun to more clearly define the domains of morality, en- compassing issues of harm, fairness, loyalty, authority, and spiritual (...) purity. Clinical descriptions and theories of psychopathy suggest that deficits may exist primarily in the areas of harm and fairness, although quantitative evidence is scarce. Within a broad sample of participants, we found that scores on a measure of psychopathy predicted sharply lower scores on the harm and fairness subscales of a measure of moral concern, but showed no relationship with authority, and very small relationships with ingroup and purity. On a measure of willingness to violate moral standards for money, psychopathy scores predicted greater willingness to violate moral concerns of any type. Results are further explored via potential mediators and analyses of the two factors of psychopathy. (shrink)

Though widely derided by popular psychologists and self-help writers as an emotionally toxic and destructive response, blame has many defenders among contemporary moral philosophers. Blaming wrongdoers has been thought to express deep commitment to moral values and norms, to be intimately bound up with practices of holding others responsible, and to be an important exercise of moral agency. In this paper I push against the grain of such defenses of blame just enough to articulate what seems right in the more (...) popular lines of critique. I distinguish between blame as a reactive attitude and blaming as a speech act, and argue that some disagreement over the value of blame can be explained by the fact that blaming, as a speech act, takes several distinct forms. Critiques of blame, I suggest, properly target what we might call judgmental or strongly verdictive blaming, the sort of blaming that passes judgment on the wrongdoer him- or herself, and treats him or her as deserving of the blamer’s hostile or “punishing” reactions. This kind of blaming, I argue, tends to foreclose engagement in further moral dialogue with wrongdoers, an effect that is particularly destructive in therapeutic contexts. In such contexts, it is often more appropriate—and more constructive—to hold others answerable without blaming them in the strongly verdictive sense. I argue, moreover, that strongly verdictive blame may be similarly destructive outside of straightforwardly therapeutic contexts, and I challenge the idea that there is in any case a sharp or clear dividing line between therapeutic and non-therapeutic responses to wrongdoers. Holding answerable in a non-judgmental mode is a response that may have a therapeutic dimension, but it nonetheless engages a wrongdoer as a moral peer and partner in moral dialogue. This account of non-judgmental answerability, I suggest, captures much of what moral philosophers have taken to be valuable about blame, while accommodating the insights of those who criticize its more toxic forms.

The article reconstructs the main lines of three hypotheses in the current literature concerning the evolutionary pace which characterized the natural history of human language: the “continuist” and gradualist perspective, the “discontinuist” and evolution-free perspective, and the “punctuationist” view. This current debate appears to have a long history, which starts at least from Darwin’s time. The article highlights the similarities between the old and the modern debates in terms of history of ideas, and it shows the current limits of each (...) of these perspectives. In the final part, we present an alternative approach which considers human language not as a single trait, but as the result of a mosaic of different elements, some of which recently evolved, and some others gradually evolved and phylogenetically ancient. When matched with a tree thinking and comparative perspective, this view suggests that expressions of symbolic and linguistic behaviors in other human species could have preceded the more complex and systematic behaviors showed by Homo sapiens.

The goal of this paper is to encourage participants in the debate about the locus of cognition (e.g., extended mind vs embedded mind) to turn their attention to noteworthy anthropological and sociological considerations typically (but not uniquely) arising from transhumanist and posthumanist research. Such considerations, we claim, promise to potentially give us a way out of the stalemate in which such a debate has fallen. A secondary goal of this paper is to impress trans and post-humanistically inclined readers to embrace (...) (or at least seriously reflect on) the extended mind thesis as a potential gamechanger to the state of play in their own debates. We start off (Sect. 1) by reviewing two crucial ideas (homo faber and plasticity of the body schema) that are instrumental in setting up the dispute between extended and embedded. We then summarise (Sect. 2), the stalemate between these two competing accounts of cognition, and review some of the dialectics underlying it. In Sect. 3, to get out of the stalemate, we propose to focus on a series of important anthropological and sociological considerations derived from and related to trans and posthumanist research. In doing so, we claim (Sect. 4) that an extended approach to cognition becomes anthropologically preferable and morally as well as socially more desirable than an embedded one. (shrink)

Human extinction is something generally deemed as undesirable, although some scholars view it as a potential solution to the problems of the Earth since it would reduce the moral evil and the suffering that are brought about by humans. We contend that humans collectively have absolute intrinsic value as sentient, conscious and rational entities, and we should preserve them from extinction. However, severe threats, such as climate change and incurable viruses, might push humanity to the brink of extinction. Should that (...) occur, it might be useful to envision a successor to humans able to preserve and hand down its value. One option would be to resort to humanoid robots that reproduce our salient characteristics by imitation, thanks to AI powered by machine learning. However, the question would arise of how to select the characteristics needed for our successors to thrive. This could prove to be particularly challenging. A way out might come from an algorithm entrusted with this choice. In fact, an algorithmic selection both at the social and at the individual level could be a preferred choice than other traditional ways of making decisions. In this sense, reflecting on human extinction helps us to identify solutions that are also suitable for the problems we face today. (shrink)

In metasemantics, semantic dispositionalism is the view that what makes it the case that, given the value of the relevant parameters, a certain linguistic expression refers to what it does are the speakers’ dispositions. In the literature, there is something like a consensus that the fate of dispositionalism hinges on the status of three arguments, first put forward by Saul Kripke ‒ or at least usually ascribed to him. This paper discusses a different, and strangely neglected, anti-dispositionalist argument, which develops (...) some remarks first put forward by Paul Boghossian and Anandi Hattiangadi and revolves around the idea that semantic dispositionalists have no way to justify their privileging certain dispositions, the ones they take to be reference-determining, over all the others. After some background (Section 1) and a first presentation of the argument (Section 2), I discuss three ways a dispositionalist might try to answer it and find them all wanting (Section 3). (shrink)

Anecdotal evidence has long lamented the status of social studies in elementary classrooms as observed by preservice teachers. As standardized testing has risen for mathematics and language arts, social studies has been pushed aside. In the aftermath of accountability legislation such as No Child Left Behind, research indicates that social studies is less visible in elementary classrooms due to an instructional focus on tested content areas (e.g. math, language arts, reading). In this study, approximately 90 elementary preservice teachers enrolled in (...) a social studies methods course responded to a survey and indicated the frequency and quality of lessons they observed over the course of a single semester. Findings report that preservice elementary teachers witnessed few, if any, lessons in social studies in the elementary classroom. Implications for teacher education are discussed. (shrink)

This paper investigates Ockhamism from a metaphysical point of view. Its main point is that the claim that future contingents are true or false is less demanding than usually expected, as it does not require particularly contentious assumptions about the future. First it will be argued that Ockhamism is consistent with a wide range of metaphysical views. Then it will be shown that each of these views leaves room for the claim that the future is open, at least on some (...) plausible interpretations of that claim. (shrink)

This paper raises some questions about the formalization of sentences containing ‘if’ or similar expressions. In particular, it focuses on three kinds of sentences that resemble conditionals in some respects but exhibit distinctive logical features that deserve separate consideration: whether-or-not sentences, biscuit conditionals, and concessive conditionals. As will be suggested, the examples discussed show in different ways that an adequate formalization of a sentence must take into account the content expressed by the sentence. This upshot is arguably what one should (...) expect on the view that logical form is determined by truth conditions. (shrink)

In a recent paper, Cassinadri raised substantial criticism about the possibility of using moral reasons to endorse the hypothesis of extended cognition over its most popular alternative, the embedded view. In particular, Cassinadri criticized 4 of the arguments we formulated to defend EXT and argued that our claim that EXT might be preferable to EMB does not stand close scrutiny. In this short reply, we point out—contra Cassinadri—why we still believe that there are moral reasons to prefer EXT over EMB, (...) hence why we think that the former is more inclusive and more progressive than the latter.

Autonomy, at least in one sense of the term, requires sovereign authority over one’s choices and actions. In this paper, I argue that such authority is relational in at least two respects. First, I argue that sovereign authority may be shared – and, indeed, must be shareable – with others through the exercise of normative powers. Second, I argue that normative powers are themselves relational powers, powers that depend in part on the recognition of agents as having an equal basic (...) authority to exercise such powers in the first place. Drawing on feminist speech-act analyses of silencing and subordination, I examine how failures of uptake for exercises of normative powers compromise personal autonomy. (shrink)

We study a class of formulas generalizing the weak law of the excluded middle and provide a characterization of these formulas in terms of Kripke frames and Brouwer algebras. We use these formulas to separate logics corresponding to factors of the Medvedev lattice.

According to a view called 'nihilism', sentences containing vague expressions cannot strictly speaking be true or false, because they lack definite truth conditions. While most theorists of vagueness tend to regard nihilism as a hopeless view, a few isolated attempts have been made to defend it. This paper aims to develop such attempts in a new direction by showing how nihilism, once properly spelled out, can meet three crucial explanatory challenges that respectively concern truth, assertibility, and communication.

Several scholars have recognized the limitations of theories of moral reasoning in explaining moral behavior. They have argued that moral behavior may also be influenced by moral identity, or how central morality is to one’s sense of self. This idea has been supported by findings that people who exemplify moral behavior tend to place more importance on moral traits when defining their self-concepts (Colby & Damon, 1995). This paper takes the next step of examining individual variation in a construct highly (...) associated with immoral behavior — psychopathy. In Study 1, we test the hypothesis that individuals with a greater degree of psychopathic traits have a weaker moral identity. Within a large online sample, we found that individuals who scored higher on a measure of psychopathic traits were less likely to base their self-concepts on moral traits. In Study 2, we test whether this reduced sense of moral identity can be attributed to differences in moral judgment, which is another factor that could influence immoral behavior. Our results indicated that the reduced sense of moral identity among more psychopathic individuals was independent of variation in moral judgment. These results suggest that individuals with psychopathic traits may display immoral behavior partially because they do not construe their personal identities in moral terms. (shrink)

This paper claims that there is no such thing as the correct answer to the question of what is logical form: two significantly different notions of logical form are needed to fulfil two major theoretical roles that pertain respectively to logic and semantics. The first part of the paper outlines the thesis that a unique notion of logical form fulfils both roles, and argues that the alleged best candidate for making it true is unsuited for one of the two roles. (...) The second part spells out a considerably different notion which is free from that problem, although it does not fit the other role. As it will be suggested, each of the two notions suits at most one role, so the uniqueness thesis is ungrounded. (shrink)

Several attempts have been made previously to provide a biological grounding for cognitive architectures by relating their components to the computations of specific brain circuits. Often, the architecture's action selection system is identified with the basal ganglia. However, this identification overlooks one of the most important features of the basal ganglia—the existence of a direct and an indirect pathway that compete against each other. This characteristic has important consequences in decision-making tasks, which are brought to light by Parkinson's disease as (...) well as genetic differences in dopamine receptors. This paper shows that a standard model of action selection in a cognitive architecture cannot replicate any of these findings, details an alternative solution that reconciles action selection in the architecture with the physiology of the basal ganglia, and extends the domain of application of cognitive architectures. The implication of this solution for other architectures and existing models are discussed. (shrink)

Increasing evidence from psychology and neuroscience suggests that emotion plays an important and sometimes critical role in moral judgment and moral behavior. At the same time, there is increasing psychological and neuroscientific evidence that brain regions critical in emotional and moral capacity are impaired in psychopaths. We ask how the criminal law should accommodate these two streams of research, in light of a new normative and legal account of the criminal responsibility of psychopaths.

This paper investigates the logic of Ockhamism, a view according to which future contingents are either true or false. Several attempts have been made to give rigorous shape to this view by defining a suitable formal semantics, but arguably none of them is fully satisfactory. The paper draws attention to some problems that beset such attempts, and suggests that these problems are different symptoms of the same initial confusion, in that they stem from the unjustified assumption that the actual course (...) of events must be represented in the semantics as a distinguished history, the Thin Red Line.

In this paper I present and assess a controversy between Edmund Husserl and Heinrich Rickert on the nature of judgment, in order to bring to light the originality of Husserl's proposal concerning this important issue. In the first section I provide some context for Rickert's theory of judgment by sketching a reconstruction of nineteenth century logical theory and then proceed to introduce Rickert's view. I suggest that nineteenth century logic is characterized by a criticism of the traditional view that sees (...) categorial judgment as the essential form of judgment and the uniting and separating of ideas as sufficient for the constitution of a judgment. Hume inaugurates this criticism, but it finds its most mature expression in the work of Lotze, Brentano, and Rickert. Rickert, in particular, sees simple affirmation and negation of the transcendent value of truth as the essence of judgment. In the second section I present Husserl's criticism of Rickert. Husserl's criticism revolves around the distinction between simple judgments and the higher-order affirmative or negative stance we can adopt with respect to previously articulated simple judgments. Simple judgments register the mereological relation holding among something and one of its properties, and they do not entail an affirmative or negative stance. Their function is to constitute states of affairs drawing on concrete perceptual situations. Higher-order affirmation or negation occurs when we set out to revisit a foregoing simple judgment in order to confirm or disconfirm the veridicality of its proposed state of affairs. In the third part I suggest a diagnosis of the origin of the mistake in earlier theories. Simple judgments are easy to conflate with non-simple, higher-order judgmental stances because they have the same logical value and they cannot be seen without the aid of genuinely phenomenological reflection. In conclusion, I suggest that Husserl's analysis amounts to a vindication of categorial judgment in its traditional form ‘S is P’, which continues to maintain a phenomenological legitimacy even in the wake of Frege's canonical dismissal of subject and predicate.

This paper employs some outcomes (for the most part due to David Lewis) of the contemporary debate on the metaphysics of dispositions to evaluate those dispositional analyses of meaning that make use of the concept of a disposition in ideal conditions. The first section of the paper explains why one may find appealing the notion of an ideal-condition dispositional analysis of meaning and argues that Saul Kripke’s well-known argument against such analyses is wanting. The second section focuses on Lewis’ work (...) in the metaphysics of dispositions in order to call attention to some intuitions about the nature of dispositions that we all seem to share. In particular, I stress the role of what I call "Actuality Constraint". The third section of the paper maintains that the Actuality Constraint can be used to show that the dispositions with which ideal-condition dispositional analyses identify my meaning addition by "+" do not exist (in so doing, I develop a suggestion put forward by Paul Boghossian). This immediately implies that ideal-condition dispositional analyses of meaning cannot work. The last section discusses a possible objection to my argument. The point of the objection is that the argument depends on an illicit assumption. I show (1) that, in fact, the assumption in question is far from illicit and (2) that even without this assumption it is possible to argue that the dispositions with which ideal-condition dispositional analyses identify my meaning addition by "+" do not exist.

Human brain organoids (HBOs) are three-dimensional biological entities grown in the laboratory in order to recapitulate the structure and functions of the adult human brain. They can be taken to be novel living entities for their specific features and uses. As a contribution to the ongoing discussion on the use of HBOs, the authors identify three sets of reasons for moral concern. The first set of reasons regards the potential emergence of sentience/consciousness in HBOs that would endow them with a (...) moral status whose perimeter should be established. The second set of moral concerns has to do with an analogy with artificial womb technology. The technical realization of processes that are typically connected to the physiology of the human body can create a manipulatory and instrumental attitude that can undermine the protection of what is human. The third set concerns the new frontiers of biocomputing and the creation of chimeras. As far as the new frontier of organoid intelligence is concerned, it is the close relationship of humans with new interfaces having biological components capable of mimicking memory and cognition that raises ethical issues. As far as chimeras are concerned, it is the humanization of nonhuman animals that is worthy of close moral scrutiny. A detailed description of these ethical issues is provided to contribute to the construction of a regulative framework that can guide decisions when considering research in the field of HBOs.

This paper develops the idea that valid arguments are equivalent to true conditionals by combining Kripke’s theory of truth with the evidential account of conditionals offered by Crupi and Iacona. As will be shown, in a first-order language that contains a naïve truth predicate and a suitable conditional, one can define a validity predicate in accordance with the thesis that the inference from a conjunction of premises to a conclusion is valid when the corresponding conditional is true. The validity predicate (...) so defined significantly increases our expressive resources and provides a coherent formal treatment of paradoxical arguments. (shrink)

In order to accommodate for the present shortage of oocyte donors, oocyte-donation programs place ads in college newspapers and provide large monetary compensation to encourage participation. Large compensation acts as a strong incentive for young women to undergo the potentially risky procedure of donation. In this enticing situation, it is particularly important for programs to fully inform prospective donors of the risks of the procedure so that they can accurately weigh the costs and benefits of donating. However, because oocyte-donor programs (...) must alleviate the shortage of donors if they wish to maintain a financially viable business, there is reason to fear that they may minimize or misrepresent risks when recruiting egg donors. In this pilot study, the risk information provided by programs (n=19) to prospective oocyte donors in a preliminary phone call inquiry was investigated. The majority of the programs provided incomplete and/or inaccurate risk information. Policy changes are recommended to reduce the potential for undue influence and to standardize and regulate the risk information provided to prospective egg donors. (shrink)
