Many of us agree that we ought not to wrong future people, but there remains disagreement about which of our actions can wrong them. Can we wrong individuals whose lives are worth living by taking actions that result in their very existence? The problem of justifying an answer to this question has come to be known as the non-identity problem.[1] While the literature contains an array of strategies for solving the problem,[2] in this paper I will take what I call (...) the harm-based approach, and I will defend an account of harming—which I call the existence account of harming—that can vindicate this approach. -/- Roughly put, the harm-based approach holds that, by acting in ways that result in the existence of individuals whose lives are worth living, we can harm and thereby wrong those individuals. An initially plausible way to try to justify this approach is to endorse the non-comparative account of harming, which holds that an event harms an individual just in case it causes her to be in a bad state, such that the state’s badness does not derive from a comparison between that state and some alternative state that the individual would or could have been in. However, many philosophers argue that the non-comparative account of harming is inadequate,[3] and one might be tempted to infer from this that any harm-based approach to the non-identity problem will fail. My proposal, which I call the existence account of harming, will show that this inference is faulty: we can vindicate the harm-based approach without relying on the non-comparative account of harming.

This chapter defends a deontological approach to both the non-identity problem and what is referred to as the “inconsequentiality problem.” Both problems arise in cases where, although the actions of presently living people appear to have harmful consequences for future people, it is difficult to explain why there are moral reasons against such actions. The deontological response to both problems appeals to a distinction between causal and non-causal consequences. By acknowledging the moral importance of such a distinction, deontologists can vindicate (...) the judgment that, collectively and individually, we have harm-based reasons against bringing about bad consequences for future people.

There are kinds of dialogue that support social justice and others that do the reverse. The kinds of dialogue that support social justice require that anger be bracketed and that hiding in safe spaces be eschewed. All illegitimate ad hominem/ad feminem attacks are ruled out from the get-go. No dialogical contribution can be down-graded on account of the communicator’s gender, race, or religion. As well, this communicative approach unapologetically privileges reason in full view of theories and strategies that might seek (...) to undermine reasoning as just another illegitimate form of power. On the more positive side, it is argued in this paper that social justice dialogue will be enhanced by a kind of “communicative upgrading,” which amplifies “person perception,” foregrounds the impersonal forces within our common social spaces rather than the “baddies” within, and orients the dialogical trajectory toward the future rather than the past. Finally, it is argued in this paper that educators have a pressing responsibility to guide their students through social justice dialogue so that their speech contributes to the amelioration of injustice, rather than rendering the terrain more treacherous.

Though Jana Mohr Lone refers to children’s striving to wonder, to question, to figure out how the world works and where they fit as the “philosophical self,” like its parent discipline, it could be argued that the philosophical self is actually the “parent self,”—the wellspring of all the other aspects of personhood that we traditionally parse out, e.g., the intellectual, moral, social, and emotional selves. If that is the case, then to be blind to “The Philosophical Child,” the latter being (...) the title of Jana Mohr Lone’s book, is, in a sense then, to be blind to the child. Thus, though Mohr Lone says that the subject of her book is to assist parents in supporting the development of children’s philosophical selves, that claim may mask the gift that this lovely book can bring to the parent-child relationship if it is interpreted as helping children to become “smarty pants” in the sense of acquiring esoteric skills to excel in the ivory-tower discipline of academic philosophy. This is not the focus of this book. This is not an invitation to learn about the history of philosophy— about what some wise, usually white, usually men said about the fundamental questions that intrigue all humans. This is not an invitation to memorize and thus to sit in awe of what others think —as is too often the case in university classrooms. This book, rather, is a guide to how to actually philosophize—how to use questions to energetically and courageously make progress toward finding answers that one, through reflection, comes to believe are the best, given the reasons and evidence available. And to the degree that we and our children are successful, we give ourselves and our children the gift of continuously learning to become ever wiser. (shrink)

A complete theory of harming must have both a substantive component and a formal component. The substantive component, which Victor Tadros (2014) calls the “currency” of harm, tells us what I interfere with when I harm you. The formal component, which Tadros calls the “measure” of harm, tells us how the harm to you is related to my action. In this chapter I survey the literature on both the currency and the measure of harm. I argue that the currency of (...) harm is well-being and that the measure of harming is best captured by a causal account on which harming is causing a harm. A harm for you is the presence of something intrinsically bad for you or the absence of something intrinsically good for you. Thus, although a counterfactual account of the measure of harm need not distinguish between an harm and a harmful event, the causal account reserves the term ‘harm’, not for a harmful event, but only for its effect. Finally, I show how a complete theory of harming can help us to answer questions about whether we can harm people with speech, whether we can harm the dead, and how it is possible to harm future generations.

According to various “harm-based” approaches to the non-identity problem, an action that brings a particular child into existence can also harm that child, even if his or her life is worth living. In the third chapter of The Non-Identity Problem and the Ethics of Future People, David Boonin surveys a variety of harm-based approaches and argues that none of them are successful. In this paper I argue that his objections to these various approaches do not impugn a harm-based approach that (...) Boonin does not consider, an approach I call the “existence solution to the non-identity problem.” I also argue that the existence solution is more plausible than Boonin’s own proposed solution.

The tragedy of the commons is a primary contributing factor in ensuring that humanity makes no serious inroads in averting climate change. As a recent Canadian politician pointed out, we could shut down the Canadian economy tomorrow, and it would make no measurable difference in global greenhouse gas emissions. When coordinated effort is required, it would seem that doing the “right thing” alone is irrational: it will harm oneself with no positive consequences as a result. Such is the tragedy. And (...) that is the challenge that we take up here. Though Garrett Hardin suggests that the solution is a governmental process that rules over all contenders, since a world government seems unlikely before the planet hits the tippy point, we suggest an educational initiative instead: one that holds a mirror up to the behaviour of individuals, rather than to the behaviour of individuals in groups. Such an educational initiative would be focused on priming individuals to keep constant track of what they do as individuals as opposed to focusing on the behaviour of humanity in general. Such an educational initiative would focus on tackling the “problem solvers” rather than just “the problem”. (shrink)

There is a long standing controversy in education as to whether education ought to be teacher- or student- centered. Interestingly, this controversy parallels the parent- vs. child-centered theoretical swings with regard to good parenting. One obvious difference between the two poles is the mode of communication. “Authoritarian” teaching and parenting strategies focus on the need of those who have much to learn to “do as they are told,” i.e. the authority talks, the child listens. “Non-authoritarian” strategies are anchored in the (...) assumption that youngsters ought to be encouraged to develop their natural interests and talents and hence that it is important to allow the children to do the talking and that adults listen. Both strategies seemed flawed due to the absence of the inherent wisdom of its opposing view. This chasm can be overcome. The Community of Inquiry, a pedagogical method used in Philosophy for Children, demands a method of communication which is able to bridge this gap. A Community of Inquiry is neither teacher-centered and controlled nor student-centered and controlled, but centered on and controlled by the demands of truth. Truth is absolutely essential to this method; it is only because of progress toward truth that participants are ultimately convinced of the fruitfulness of the process. Truth, however, is a hard taskmaster; it places severe restrictions on participants and puts exacting demands on the facilitator. These inherent restrictions and demands are too often underplayed, overlooked and sometimes seemingly overtly denied by those who, quite correctly emphasize that ultimately this method depends on maintenance and enhancement of student autonomy. This underrating of the role of the facilitator has led to a severe undervaluing of this otherwise brilliant pedagogical method, but worse, it has left novice teacher/facilitators ill prepared to utilize this method successfully.

There is a clear distinction between genuine and fraudulent reasoning. Being seduced by the latter can result in horrific consequences. This paper explores how we can arm ourselves, and others with the ability to recognize the difference between genuine and pseudo-reasoning, with the motivation to maintain an unbending commitment to follow the “impersonal” “norm-driven” rules of reason even in situations in which “non-reasonable” strategies appear to support short-term bests interests, and with the confidence that genuine reasoning is the best defense (...) against the pseudo-reasoning. It also provides a simple table of “markers” whereby genuine reasoning can be distinguished from the “fake stuff.”. (shrink)

Dedication: I would like to dedicate this essay to Mort Morehouse, whose intelligence, warmth, and good humour sustains NAACI to this day. I would like, too, to dedicate this essay to Nadia Kennedy who, in her paper “Respecting the Complexity of CI,” suggests that respect for the rich non-reductive emergent memories and understandings that evolve out of participating in the sort of complex communicative interactions that we experienced at the 2012 NAACI conference requires “a turning around and looking back so (...) that we might understand it better.” Thus, though “we cannot grasp the essence of the system in some determinate way, since each description provides a limited view, and portrays some aspect of the system from a specific position inside or outside it, and at a specific point in time,” nonetheless respect requires that we try “to take different ‘snapshots’ of such systems and attempt to make sense of them.” It is as a result of this urging that the following snapshot was attempted. My thanks to Nadia for being such an inspiration, and to all the participants for making this conference such a memorable occasion. (shrink)

That the world is awash with resentment poses a genuine question for educators. Here, we will suggest that resentment can be better harnessed for good if we stop focusing on people and tribes and, instead, focus on systems: those invisible norms that often produce locked-in structures of social interaction. A “systems lens” is vast, so fixes will have to be an iterative process of reflection, and revision toward a more just system. Nonetheless, resentment toward the status quo may be an (...) important element in keeping that otherwise tedious process going, with the caveat that resentment is only productive when it is combined with reason, and that, therefore, educators, rather than privileging participant reactive attitudes, ought, instead, to promote participant reactive reasoning, as the latter can be a genuine force for both personal and interpersonal growth, while the former might very well do the reverse.

In this paper I offer a selective, systematic rather than historical account of Merleau-Ponty’s highly complex relation to classical German philosophy, focussing on issues which bear on the question of his relation to transcendentalism and naturalism. I argue that the concerns which define his project in Phenomenology of Perception are fundamentally those of transcendental philosophy, and that Merleau-Ponty’s disagreements with Kant, and the position he arrives at in The Visible and the Invisible, are helpfully viewed in light of issues which (...) Merleau-Ponty identifies as raised by Kant’s Critique of the Power of Judgement, and Schelling’s conversion of Kantian idealism into a Real-Idealismus. Finally I address the question of whether, and on what basis, Merleau-Ponty’s claim to have surpassed systematic philosophy can be defended. (shrink)

Given that one of the major goals of the practice of Philosophy for Children (P4C) is the development of critical thinking skills (Sharp 1987/2018, pp. 4 6), an urgent question that emerged for one of the authors, who is of Chinese Heritage and a novice practitioner at a P4C summer camp was whether this emphasis on critical thinking might make this practice incompatible with the fabric of Chinese culture. Filial piety (孝), which requires respect for one’s parents, elders, and ancestors (...) is considered an important virtue in Asian culture, as is the preservation of harmony. But if one of the goals of P4C is to teach youngsters to courageously pursue reasoned dialogue, does this not set-up young Asians for serious conflict when they come face-to-face with positions that are articulated by elders, but which are ones to which they are diametrically opposed; a racist grandmother, for instance, or an uncle who insists that those at the Tiananmen Square uprising were nothing but hooligan’s. It is this question that we will explore in this presentation. In the process, we will come to the conclusion that, when positions seem irreconcilable, rather than continuing to pursue rigorous critical interchange that may do little other than escalate insult, the facilitator, rather, ought to move toward creating a deeper understanding of each position juxtaposed against its opposing view (a process that we refer to as ‘collaborative caring’), so as to produce side-by-side understanding, knowing that communal bonds have been maintained and, hence, that the opportunity for genuine reasoned collaborative inquiry on other issues and at future times remains open.

This paper argues that juridification has become the enemy of legality. By 'juridification' is meant the proliferation of legal norms and legally recognized norms. By legality is meant conformity with the ideal of the rule of law. The paper begins with the most obvious ways in which juridification threatens legality. Too much law makes the law on any subject hard to discover, hard to remember, and hard to follow. It also makes us too dependent on the discretion of petty officials, (...) who are therefore not sufficiently constrained by law. But the paper looks beyond the discretion of petty officials and argues that, in a way, the biggest threat to legality of our age comes from the proliferation of contractual norms, and the increasing diversion of contractual dispute-resolution into arbitration (and other ADR processes). The paper argues that those who rely on the law to recognise contracts should be subjected to an non-excludable jurisdiction of the courts in respect of all questions of law arising under those contracts, including their proper legal meaning. A compulsory arbitration clause, in other words, should be valid only subject to extensive judicial review of the arbitrator’s decisions. It is argued that contractual arbitration (and other ADR) that does not meet this condition is free-riding on the work of courts and professional lawyers, and should be regarded as antisocial – and that this is true even when it does more perfect justice between the parties.

Marshalling a mind-numbing array of data, Harvard political scientist Robert D. Putnam, in his book Bowling Alone, shows that on virtually every conceivable measure, civic participation, or what he refers to as “social capital,” is plummeting to levels not seen for almost 100 years. And we should care, Putnam argues, because connectivity is directly related to both individual and social wellbeing on a wide variety of measures. On the other hand, social capital of the “bonding kind” brings with it the (...) ugly side effect of animosity toward outsiders. Given the increasing heterogeneity of our world, the goal therefore must be to enhance connectivity of the “bridging sort,” i.e., connecting across differences. This, in turn, requires that we first clarify what bridging communicative styles looks like. Examining communication as it might transpire in Kant’s kingdom of ends, through the perspective of Habermas’ “communicative action,” and within the scientific community, offers a compelling suggestion that there is a way of communicating such that, if adopted, one would come to view others as if they were persons, i.e., that a bridging communicative style facilitates a kind of bonding that sees through differences toward the commonality of personhood. This paper will briefly explore how communicating toward personhood might be promoted. (shrink)

The use of evidence to resolve uncertainties is key to many endeavours, most conspicuously science and law. Despite this, the logic of uncertainty is seldom taught explicitly, and often seems misunderstood. Traditional educational practice even fails to encourage students to identify uncertainty when they express knowledge, though mark schemes that reward the identification of reliable and uncertain responses have long been shown to encourage more insightful understanding. In our information-rich society the ability to identify uncertainty is often more important than (...) the possession of knowledge itself. In both science and law there are fundamentally different kinds of uncertainty at issue. There is uncertainty whether a particular hypothesis is correct, and there is uncertainty about observable data that may be generated if a particular hypothesis is correct. Both are expressed in terms of probabilities. Each has its own domain of application and its own logic, but the inter-relationship is complex and sometimes misunderstood. Hypothesis probabilities are always open to error through possible failure to take account of realistic alternatives, while the proper inferences that can be drawn from data probabilities (often in the context of significance testing) are quite limited and easily over-interpreted. When considering these two kinds of probability in a court of law it is possible to interpret the phrase 'reasonable doubt' in different ways. It can be seen as addressing data uncertainty: whether such incriminating evidence might with reasonable probability arise to confront an innocent person. Or (the more conventional view) it can be seen as some sort of threshold level on the probability that the defendant is guilty (a hypothesis probability). Each typically involves elements of subjective judgement, but fewer issues and uncertainties arise when considering the data probability and it is argued that this is often the more critical and proper issue for a jury to address. This has particular repercussions for cases involving identification of a suspect through trawl of a DNA or other database. (shrink)

Philosophy has a dirty little secret and it is this: a whole lot of philosophers have swallowed the mechanistic billiard ball deterministic view of human action—presumably because philosophy assumes that science demands it, and/or because modern attempts to articulate in what free will consists seem incoherent. This below-the-surface-purely-academic commitment to mechanistic determinism is a dirty little secret because an honest public commitment would render virtually all that is taught in philosophy departments incomprehensible. Can “lovers of wisdom” really continue to tolerate (...) such a heavy burden of hypocrisy? For it is maximally hypocritical, is it not, to teach ethics, or existentialism, or political philosophy, or critical thinking, or indeed to teach anything at all if one views the bodies of humans as entities determined by forces that are describable entirely under the auspices of physical/chemical laws. The only option, it would seem, to avoid such hypocrisy is to go out of business. After all, either base metal can be turned into gold, or it cannot. We found out long ago that it cannot, and so alchemy was rightly banished into the dustbin of history. Likewise, either philosophy can enhance the wisdom quotient of its disciples as its name implies, and thus override billiard ball mechanics, or it cannot. And if it cannot, it deserves to follow alchemy to an ignominious end. (shrink)

If you cannot, then you ought not. Taking its own precepts seriously, philosophy, in the face of scientific deterministic success, has abandoned its original calling of inspiring munificence and, in doing so, has undercut much of its own relevance. But this need not be the case. If we adopt a more finely grained set of theoretical glasses, we will see that human freedom is simply the icing on a deterministic layer cake that launches entities, both phylogenetically and ontogenetically, from the (...) object base, through consciousness, and then through self-consciousness, and finally to the possibility of reasonably based self-legislation. Greasing the wheels of the last step is Philosophy’s calling and responsibility. We can—and we ought because we can—fall inline with the Socratic echo, and agitate for munificence. (shrink)

In the face of disobedience, and in the name of the short-term goal of a smooth-functioning and/or happy household, parents often feel caught between two diametrically opposed parenting strategies; make it happen or let it go. However, either strategy of dictator or friend can seriously jeopardize a child’s long-term best interests. If children, adolescents, young adults, full adults or oldsters are even to hear, let alone reasonably answer, the prudential and ethical “whys” that their intended actions scream, they will need (...) to attend to health of their unique human capacity to reason. They will need to understand deeply that reason is not a capacity to be used solely in academic endeavors and/or for making a living, but rather that reason’s prime function is to assist in making the best of all possible lives. If parents want their children to understand this, then they need to walk the talk and invite reason into their homes. The result will be that authoritarian parents will need to let go, while “parents as friends” will need to belly up to the bar, in order to entrench the first rule of a reasonable household and that is that the best reason always wins.

Though central to metaphysics, and exciting for entertainment, the fact that selves are invisible, has received insufficient attention in the field of P4C, and virtually none in the field of education in general. This may not be surprising as the enthusiasm to enrich “minds” both with essential information as well as with critical, creative, and cooperative inquiry skills, may blind educators to the fact that their initiatives (even those that are dialogical) may not touch how children view themselves, nor how (...) they ought to function in the world as they find it. It will be argued here that, if ethical development, or democratic citizenship, or authenticity, or any other “self-education” initiative is on the educative menu, strategies (detailed here) must be undertaken to ensure that all parties are truly present, in body, mind and self. It will be further argued that since educating selves can be done at the same time as educating minds (e.g., nurturing reasoning skills), and since a Community of Philosophical Inquiry (unlike other educational strategies), in its dialogical structure, has the unique potential to solicit and hence educate selves, and since such “self-education” is an education for “making a life,” rather than the more common educative concern of educating for “making a living,” facilitators who do not activate the unique power of a CPI to enhance personhood are remiss in their responsibility to their charges.

In this dissertation, I explicate some of the moral duties we have to future humans. I defend the view that (DV1) we have pro tanto duties of nonmaleficence and beneficence to and regarding at least some future humans; (DV2) in the present circumstances, this duty of nonmaleficence grounds reasons for us to refrain from damaging certain features of the natural environment; and (DV3) in the present circumstances, this duty of beneficence grounds reasons for at least some of us to bring (...) future humans into existence. I refer to the view consisting of (DV1) - (DV3) as the Duties to Future Humans View (DV). In defense of DV1, I argue that future humans have moral standing, and that their having moral standing is sufficient for our having pro tanto duties of nonmaleficence and beneficence to and regarding them. I take a duty of nonmaleficence to be a duty to refrain from harming and a duty of beneficence to be a duty to benefit. In defense of DV2, I argue that increases in the concentration of carbon dioxide in the atmosphere and numerous species extinctions are harms for future humans. In defense of DV3, I argue that having a life worth living is a benefit to the person who lives that life. One objection to DV is the non-identity problem. In response, I defend substantive accounts of harming and benefiting. The account of harming holds that for any individual having moral standing, S, and any state of affairs, A, (1) A is a harm for S just in case if it were true that both S existed and A did not obtain, then S would have a higher level of lifetime well-being; (2) an action or event harms S just in case it causes a harm for S to obtain; (3) other things being equal, the reason against harming S is stronger, the more similar the world would be if A did not obtain. I argue for a similar account of benefiting. I also argue for a metaphysical distinction between causes and mere conditions. (shrink)

There is an unacknowledged disagreement on what kind of dialogue best supports democracy. Many view democracy as analogous to a law court and so view “democratic dialogue” as a contest between competing advocates who have acquired the kind of “steel trap” critical thinking skills that are ideal for winning in the external marketplace of ideas. Others assume that the propensity to seriously reflect on opposing viewpoints within the minds of individuals is ideal for democratic maintenance. It will be argued here (...) that our love affair with “critical thinking” that tends to support an external battle of ideas harms democracy. It will be argued that the complexity of our common humanity, the complexity of our form of governance, the complexity of the approaches needed to face wicked problems, and the complexity of the internal engine of personal development requires that we learn to readily engage in open truth-seeking dialogue with those who hold opposing viewpoints and in so doing, enhance the dimensionality through which we view the world. With regard to the educational implications, this suggests that, since engaging in dialogue across difference is the essence of the pedagogical framework that anchors Philosophy for Children, Philosophy for Children ought to be embraced as an essential component of any educational enterprise that views cultivating democratic citizenship as part of its mandate.

It is difficult to be a philosopher in this postmodern era. This is so because philosophers, who heretofore have been the archetype of persons eager to engage in reasoned discourse, regardless of their differences, suddenly seem unable to talk to each other, primarily due to claim by postmoderns that non-postmoderns are naïve in their blindness to the fact that truth the claims cannot be true in any objective sense, and that claims to objectivity have been used maliciously throughout the ages (...) to wield oppression. After exploring some of the seductive arguments of the post-modern position, and suggesting a re-working of the non-post-modern position, this paper will conclude that philosophical educators carry a heavy responsibility for limiting the real-life damage that has been produced by this philosophical truth-storm by siding firmly with its less contentious opposite by becoming guardians of the possibility that claims can be false.

In his 2004 article “Hannah Arendt and Jean Baudrillard: Pedagogy in the Consumer Society,” Trevor Norris bemoans the degree to which contemporary education’s focus can increasingly be described as primarily nurturing “consumers in training.” He goes on to add that the consequences of such “mindless” consumerism is that it “erodes democratic life, reduces education to the reproduction of private accumulation, prevents social resistance from expressing itself as anything other than political apathy, and transforms all human relations into commercial transactions of (...) calculated exchange.” This, then, is the challenge of the age: to articulate the sort of education that might prompt our youngsters to imagine a genuine alternative to this consumer madness—a challenge that the authors of this paper attempt to tackle.

When Mathew Lipman first introduced Philosophy for Children to the world, his goal was not to sneak a little academic philosophy into the typical school curriculum, as one might expect from the titles of his first books: Philosophy in the Classroom and Philosophy Goes to School. His goal, rather, was to create a paradigm shift in the field of education itself: namely, to transform the typical hierarchical model into one in which the teacher/facilitator solicits responses from students and hence, in (...) that sense, meets them where they “are at.” This non-hierarchical model, however, has stumbled in taking root, which is, perhaps, not surprising given that the hierarchical model, whether in school, in sport or in the home, appears to be so much easier and so much more efficient. If those of us who support a non-hierarchical model in all these arenas are serious about furthering this approach, it would appear that the onus lies with us to articulate precisely in what ways a hierarchical model falls short. In so doing, we will not only provide ourselves with a precise framework by which to make the case for the importance of adopting a non-hierarchical approach, we will also provide ourselves with a metric whereby we can measure whether our own non-hierarchal practice is true to its justification; and that the approach is not simply non-hierarchal for sake of being non-hierarchical, nor quasi-authoritarianism for the sake of more wide-spread acceptance. It is the articulation of the flaws of a hierarchical model that non-hierarchal model can correct that will be the focus of the analysis here. (shrink)

This classic collection of essays, first published in 1968, represents H.L.A. Hart's landmark contribution to the philosophy of criminal responsibility and punishment. Unavailable for ten years, this new edition reproduces the original text, adding a new critical introduction by John Gardner, a leading contemporary criminal law theorist.

It is an irony to attack a more sceptical epistemology than one's own in the name of scepticism and defend, instead, an epistemology that is positively illogical. And yet that is what Martin Gardner has done in his “A Skeptical Look at Karl Popper.”.

It has recently been suggested that Merleau-Ponty’s position in Phenomenology of Perception is a unique form of transcendental idealism. The general claim is that in spite of his critique of “Kantianism,” Merleau-Ponty’s position comes out as a form of transcendental idealism that takes the perceptual processes of the lived body as the transcendental constituting condition for the possibility of experience. In this article I critically appraise this claim. I argue that if the term “idealist” is intended in a sufficiently similar (...) sense to Kant’s usage of the term in naming his position as a “transcendental idealism” then it is a misrepresentation to subsume Merleau-Ponty’s position under that term. This is because Merleau-Ponty rejects the transcendental metaphysics of the reflecting subject that underpins transcendental idealism. In its place he advocates a methodological transcendentalism that, whilst being anti-realist, is not idealist. Thus to call his position “a new kind of transcendental idealism,” as Sebastian Gardner has, is to misunderstand the significance of his existentialist break with what he sees as the “intellectualism” of this position.

REPRODUÇÃO ANIMAL: TRANSFERÊNCIA DE EMBRIÕES EM ANIMAIS, E A INDÚSTRIA DE EMBRIÕES NO BRASIL -/- ANIMAL BREEDING: EMBRYO TRANSFER IN ANIMALS, AND THE EMBRYO INDUSTRY IN BRAZIL Apoio: Emanuel Isaque Cordeiro da Silva Departamento de Zootecnia da UFRPE E-mail: [email protected] WhatsApp: (82)98143-8399 -/- 1. INTRODUÇÃO A técnica da inseminação artificial tornou possível aumentar o impacto na descendência de touros geneticamente superiores em termos de produção láctea das filhas. Com a transferência de embriões é possível aumentar o impacto da fêmea sobre (...) a população das filhas. A transferência de embriões data de 1890, ano em que Heape obteve o nascimento de coelhos transferindo ovócitos fecundados de uma fêmea para outra. A partir de 1930, é repetida uma série de experiências para desenvolver a técnica e aplicá-la em ovinos, caprinos (1934) e bovinos (1951) como espécies mais idôneas para a reprodução. A Inglaterra e os Estados Unidos estabeleceram as bases para o comércio de embriões durante os anos sessenta e setenta. De forma resumida, a transferência de embriões implica na estimulação da produção de ovócitos mediante a aplicação de hormônios: cerca de 6-8 dias após a cobrição dessas fêmeas ou da sua inseminação artificial, os óvulos fertilizados são extraídos dos órgãos genitais da fêmea doadora por perfusão ou lavagem com soluções biológicas controladas e testadas, originando-se uma deposição dos gametas fecundados nas fêmeas receptoras que serão encarregadas de levar adiante a gestação e o parto sem influência sobre as produções do novo indivíduo. 2. MANEJO DAS FÊMEAS DOADORAS É relativamente fácil obter um embrião, uma vez que pode origina-se a partir do cio natural das vacas cíclicas. No entanto, a fim de otimizar a técnica, o normal é «superovular» a fêmea doadora e obter um número superior de gametas fecundadas após cada lavagem ou perfusão das genitais. A maioria das fêmeas doadoras são tratadas com gonadotrofinas (PMSG) ou com hormônios estimuladores da foliculogênese (FSH). Estes hormônios invertem a atresia normal de folículos permitindo uma maturação, que em condições normais não se realizaria. O mecanismo exato do funcionamento destas hormonas não é totalmente claro. A superovulação multiplica por um fator de 10 o número de ovócitos recuperados no caso das vacas, ovelhas e cabras, mas apenas por um fator 2 ou 3 no caso das porcas. Existe um acordo geral sobre a utilização das gonadotrofinas; a PMSG deve ser aplicada durante a transição da fase luteica para a folicular, ou seja, no 16º dia do ciclo. As doses de gonadotrofinas variam entre 1500 e 3000 UI em bovinos, aumentando a resposta e a variabilidade individual com o aumento da dose. A resposta ao tratamento varia de acordo em função de diversos fatores. Neste contexto, merecem especial atenção a espécie, a raça, a época e a conformação corporal do animal, bem como o lote de fabricação da preparação hormonal (quadro 7.1). Estudos demonstram que, nos bovinos, as raças de corte respondem melhor ao tratamento do que as raças leiteiras.

O FSH também é utilizado para superovulação em várias espécies. Nos ovinos, injetam-se 2 mg desta hormona 12 horas antes da retirada das esponjas, aplicando-se mais três injeções, com um intervalo de 12 horas, até 24 horas após a retirada das esponjas, o que corresponde a um total de 8 mg de FSH injetados por tratamento e animal. Às vezes, e dependendo do país, existem dificuldades para a obtenção desse hormônio em condições de pureza adequada para que o tratamento proporcione o resultado esperado. Nas vacas dadoras devem ter passado mais de 50 dias após o último parto: também ser animais cíclicos, encontrar-se num nível nutricional elevado e em aumento, sem deficiências especificas alimentares. Existe uma indicação de suplementação das fêmeas doadoras com minerais essenciais antes do tratamento. 3. OBTENÇÃO DE EMBRIÕES Uma vez as fêmeas doadoras inseminadas, entre o sexto e o oitavo dia, procede-se a coleta dos embriões. Para isso, atualmente se utilizam cateteres de obtenção transcervical (tipo Foley, Rusch. etc.) munidos de uma bola insuflável na sua extremidade que permite criar um compartimento estanque na parte distal do córneo uterino e proceder ao arrasto dos embriões ali localizados. Para obter esta «lavagem» utiliza-se uma solução aquosa tamponada: o meio mais frequentemente utilizado é o tampão fosfato salino (PBS: pH = 7; PO = 280 - 290 mOsm/kg) suplementado com antibióticos e proteínas. Depois de recuperado o meio de lavagem, os embriões devem ser isolados do volume total, avaliados segundo critérios do Manual da Sociedade Internacional de Transferência de Embriões de acordo com seu estado de desenvolvimento. Código numérico para determinar o grau de desenvolvimento embrionário: N° 1: ovócito não fertilizado ou embrião de uma célula (1 dia). N° 2: Identifica embriões com 2 a 16 células (2-4 dias). N° 3: Identifica mórulas adiantadas (5-6 dias). N° 4: Identifica mórulas compactas de 6 dias de idade. N° 5: blastocisto adiantado (7 dias). N° 6: blastocisto (7-8 dias). N° 7: blastocisto expandido (8-9 dias). N° 8: blastocisto eclodido (9 dias) a partir do nono ou décimo dia o blastocisto já está fora da zona pelúcida. Além da classificação por estado de desenvolvimento, a referida Sociedade Internacional estabeleceu uma categorização dos embriões com base na qualidade dos mesmos. Assim os denomina: 1: excelente; 2: bom; 3: regular; 4: degenerado. Segundo as investigações de diversos autores especialistas no tema não devem ser transferidos embriões que não tenham sido classificados como excelentes ou bons. A obtenção dos embriões pode ser realizada em uma clínica, em unidades móveis especializadas, ou na própria fazenda. Em todo o caso, a doadora não deve apresentar quaisquer sintomas clínicos de doença, sendo esta responsabilidade direta do veterinário. O rebanho de onde provém a doadora deve estar livre de medidas cautelares sanitárias. Os técnicos devem estar adequadamente limpos e preparados para esta atuação, em um lugar tranquilo e que permita a colocação de equipamentos e material em condições limpas e seguras. 4. TÉCNICAS DE TRANSFERÊNCIA DE EMBRIÕES Recomenda-se que os embriões sejam transferidos o mais rápido possível depois da recuperação. A fêmea receptora deve apresentar um ambiente uterino o mais semelhante possível ao da fêmea doadora. Isto quer dizer que a receptora também será mantida num sistema de sincronização para que coincida o mais possível o estágio de desenvolvimento embrionário com seu correspondente estado uterino. A margem de assincronia para evitar efeitos indesejáveis é de ± 24 horas. Os métodos hormonais de sincronização são análogos aos das doadoras. As técnicas para a deposição dos embriões no seu novo habitat podem ser igualmente cirúrgicas e não cirúrgicas, mas devido aos problemas do uso de anestésicos em técnicas cirúrgicas, as transferências foram direcionadas para modelos não-cirúrgicos ou transcervicais. Este método é baseado na utilização do colo uterino de forma análoga como é realizada na inseminação artificial. Devido às relações entre o embrião e o ovário, as porcentagens de fertilidade são aumentadas ao serem depositadas no corno ipsilateral no ovário que se encontra ativo. A utilização desta técnica implica na obtenção de mais fêmeas gestantes. O uso de novilhas como fêmeas receptoras aumenta também a taxa de gestações a partir de uma maior facilidade de manejo, uniformidade na resposta hormonal e um custo mais baixo. O fator humano ou habilidade do técnico que realiza esta técnica também constitui um fator que influencia decisivamente no êxito da transferência, encontrando-se variações de 20 a 60% devidas a este fator. 5. CONTROLES SANITÁRIOS Com a utilização da inseminação artificial, verificou-se que, embora as tecnologias reprodutivas colaborativas fossem mais avançadas em termos de técnicas destinadas a aumentar a produtividade individual, da mesma forma, podem constituir um perigo de contaminação e de dispersão de doenças estrangeiras para o grupo ou rebanho para onde são transferidos os novos genes. Neste contexto, a transferência embrionária (TE) deve realizar-se tendo em conta os riscos que pode implicar uma manipulação inadequada. Uma vez mais, a Sociedade Internacional (IETS) na Reunião Regional da OIE (Oficina Internacional de Epizootias) estabeleceu as normas em 1985 para que a TE pudesse ser utilizada como meio para controle de doenças na pecuária. Para que a utilização da TE se realize sem risco para a saúde, é necessário ter em conta um certo número de regras e condições específicas que evitem os riscos de contaminação. O embrião está separado do meio externo por três barreiras de proteção: o corpo da mãe, o útero por si só e a terceira, e mais importante, pela zona pelúcida, a qual nos animais domésticos tem demonstrado ser totalmente impermeável a qualquer elemento patogênico, desde que fique intacta. Portanto, o risco de contaminação dos embriões pode vir por duas vias diferentes: a) Fatores extrínsecos - por invasão dos agentes patogênicos na cavidade uterina principalmente. Isto está relacionado com o estado sanitário médio do país, região ou rebanho de origem. b) Fatores intrínsecos - Segundo Thibier podemos considerar diferentes fontes potenciais de contaminação, que segundo o risco sanitário se classificam nas seguintes ordens: 1° Zigoto. 2° Penetração. 3° Absorção. 4° Armazenamento. 5° Exame. 6° Transferência. Os esforços para que os embriões se tornem livres de contaminação devem ser semelhantes aos que são efetuados com os animais vivos e com as doses seminais. O momento mais perigoso encontra-se entre a coleta das células fecundadas e a sua deposição, após seu exame, no trato reprodutivo da receptora. As condições em que o referido processo deve ser realizado encontram-se detalhadas no manual da Sociedade Internacional de Transferência de Embriões (IETS). 6. REGRAS DA IETS A transferência de embriões é a via mais segura para a troca de genes. No entanto, os técnicos devem esforçar-se por manter todas as regras e normas sanitárias para que a coleta e a manipulação dos embriões se realizem sob condições de absoluta garantia higiênica e sanitária. A transferência embrionária implica, pela primeira vez na história da medicina veterinária, que a vigilância sanitária não se aplica estritamente ao animal, uma vez que, na sua fase "in vitro", está inteiramente sob o controle do técnico. Por conseguinte, não haverá futuro para este tipo de biotecnologia se, paralelamente, não houver um elevado nível de garantia de que não «servirá» para não disseminar ou difundir doenças. As conclusões da Sociedade Internacional de Transferência de Embriões (IETS) na sua reunião anual de 14 de Janeiro de 1992 estabelecem, tendo em conta a revisão efetuada em 1991 pela Subdireção de Investigação e pelo Comitê de Importação e Exportação, uma classificação das doenças. Esta classificação corresponde às seguintes categorias: Categoria 1 - Doenças ou agentes de doenças para as quais foram recolhidas provas suficientes para afirmar que o risco de transmissão é negligenciável, desde que os embriões sejam corretamente manipulados entre a coleta e a transferência: a) Leucose bovina enzoótica. b) Febre aftosa (bovinos). c) Língua azul (bovinos). d) Brucelose bovina. e) Rintraqueíte infecciosa bovina. f) Doença de Aujeszky. Categoria 2 - Doenças para as quais foram recolhidas provas substanciais que indicam que o risco de transmissão é insignificante, desde que os embriões sejam corretamente manipulados entre a coleta e a transferência, mas para as quais é necessário verificar os dados existentes através de novas transferências: a) Peste suína clássica. Categoria 3 - Doenças ou agentes de doenças para as quais os resultados preliminares indicam que o risco de transmissão é insignificante, desde que os embriões sejam corretamente manipulados, entre a coleta e a transferência, mas para os quais essas verificações preliminares devem ser corroboradas por dados experimentais complementares "in vitro" e "in vivo": a) Peste bovina. b) Diarreia viral bovina. c) Língua azul (ovinos). d) Febre aftosa (suínos, ovelhas e cabras). e) Campylobacter fetus (ovinos). f) Doença vesicular do porco. g) Peste suína africana. h) Prurido lombar (ovinos). i) Haemophilus somnus. Categoria 4 - Doenças ou agentes de doenças que foram ou são objeto de trabalhos preliminares: a) Vírus Akabane (bovino). b) Estomatite vesicular (bovinos e suínos). c) Chlamydia psittaci (bovinos e suínos). d) Ureaplasma/micoplasmose (bovinos e caprinos). e) Maedi-visna (ovino). f) Adenomatosa pulmonar (ovino). g) Prurido lombar (caprinos). h) Língua azul (caprinos). i) Artrite e encefalite caprina. j) Parvovírus (suíno). k) Enterovírus (bovinos e suínos). I) Leptospirose (suíno). m) Herpesvírus 4 dos bovinos. n) Mycobacterium paratuberculose (bovinos). o) brucelose ovina. p) Doença de Border (ovinos). q) Vírus parainfluenza 3 (bovinos). r) Agente da encefalopatia espongiforme bovina. É interessante salientar que apenas seis doenças estão incluídas na categoria 1 (a mais segura). Isso não significa que as outras doenças tenham um risco maior, apenas indica que o risco de transmissão das doenças da categoria 1 é irrelevante, estatisticamente falando. É importante assinalar que as doenças mais importantes dos bovinos se situam na categoria 1. Isto significa que a incidência do embrião patogênico nos bovinos parece ser perfeitamente controlável, desde que sejam adotadas metodologias adequadas. Isto serve também como linha de defesa adicional para que o técnico centre sua atenção e cuidados entre a fase de obtenção e a de transferência. 7. SITUAÇÃO ATUAL DA TRANSFERÊNCIA DE EMBRIÕES ANIMAIS NO BRASIL O Brasil é um dos grandes responsáveis mundiais pela implantação da tecnologia na reprodução animal, sendo assim, o país conseguiu inserir-se no mercado internacional como um dos maiores produtores de embriões in vivo e in vitro. Nas últimas duas décadas, especialmente entre os anos de 1997 e 2017 o país passou por importantes transformações nesse segmento, dentre essas transformações vale destacar a posição relativa do Brasil no contexto mundial. O Brasil passou de referência regional, nos anos 1990, para se tornar o maior produtor mundial de embriões entre os anos 2012 e 2013, sendo líder no uso e na produção de embriões in vitro. Os primeiros registros da TE produzidos in vivo no Brasil datam da década de 1980, e uma década depois o país já tornara-se referência e detinha um mercado consolidado de produção e TE na espécie bovina. Não obstante, no ano de 1997 o país ainda era referência apenas no contexto regional, detendo 68,3% dos embriões transferidos na América Latina, esse percentual corresponde a 24.085 embriões de um total de 35.254 produzidos na América Latina. Esse percentual regional representa apenas 6,6% de toda a produção mundial de embriões in vivo, que produziu, em 1997, 360.656 embriões in vivo. Nos últimos anos, o mercado de embriões, principalmente o bovino, teve retração moderada de -2,5% ao ano entre 2003 e 2018, porém essa retração contrasta com o ligeiro crescimento observado a partir dos anos 2000 conforme figura 1: Figura 1: Produção de embriões bovinos no Brasil no período 1996-2018, total e por tecnologia adotada (in vivo[IVD] ou in vitro [IVP]). Em 2018, o mercado de embriões bovinos manteve-se inalterado se compararmos com os três anos anteriores, houve reduções nós segmentos de corte, leite e no total comparado ao ano de 2017. Em 2014, a produção de embriões para melhoramento do gado leiteiro teve seu ápice, porém de lá para cá esse mercado manteve-se estagnado como demonstra a tabela 2. Tabela 2: Produção de embriões bovinos no Brasil em 2018, estratificada por segmento e por tecnologia adotada (in vivo ou in vitro). 7.1 Crise, economia e mercado de embriões A indústria de embriões reflete, em maior ou menor grau, o momento da economia brasileira. Apesar do segmento agropecuário ser um setor em constante crescimento no país, ao qual, sem dúvidas, em meio a inúmeras crises mantém-se em constante crescimento. Porém vale ressaltar que esse mercado é emergente e está refletido em paralelo com os bens produzidos pelo país, como demonstra a figura 2. Figura 2: Produção de embriões bovinos e variação no produto interno bruto (PIB) no Brasil, no período 1996-2018. Cada vez mais o setor agropecuário do Brasil investe em novas tecnologias que maximizem o mercado e que melhore a produção dos animais seja no segmento corte ou leite. Segundo a OCDE, 1997, essa indústria da produção de embriões é um conjunto de novas técnicas e processos, frutos do desenvolvimento técnico-científico, que chega ao mercado e - o mais importante - o transforma. Logo, todas essas técnicas e biotecnologias visam, além da alta produção e do lucro, o melhoramento e a suplementação alimentícia da população mundial que está em crescente avanço. A evolução da tecnologia embrionária no país, seja para o melhoramento dos equinos para os esportes como as vaquejadas, hipismo, corridas, etc., onde são investidos tempo, dedicação e dinheiro para formar um novo animal que apresente força, conformação, conversão alimentar e que custa milhões, em muitos casos, não só dos equinos, mas também dos caprinos, ovinos, suínos e até mesmo os bovinos onde o mercado da TE é mais presente e aquecida, venceu os estigmas do “modismo” e o chamado “elitismo”, porém deve enfrentar novos desafios, em especial num contexto de forte concentração do mercado de genética e de concorrência globalizada. Mesmo com todos esses avanços e retrocessos, essa relativização dos números demonstra que um percentual bastante reduzido das fêmeas bovinas que estão em idade reprodutiva é utilizado para a técnica da transferência de embriões, e que o mercado brasileiro ainda tem um grande potencial de crescimento no setor de produção in vivo e in vitro. 8. RESUMO E PRIMEIRAS CONCLUSÕES Ao longo deste trabalho pretendi realizar uma revisão sumária sobre um tema de grande importância presente, e sobretudo futura; referir-me à transferência embrionária. Atualmente, esta técnica atingiu um grau notável de penetração, a nível prático, no gado leiteiro. No entanto, num futuro mais ou menos longínquo, não temos dúvidas quanto a esta técnica, pelas vantagens indubitáveis que apresenta a nível de avanço genético, que será aplicada em outras espécies úteis ao homem. Na minha exposição, tentei dar especial ênfase a dois aspectos: as técnicas de transferência, incluindo as normas IETS e os controles sanitários a serem efetuados. Por fim, a indústria brasileira de embriões mostrou-se em retrocessos e avanços, porém o mercado ainda têm grandes desafios a serem enfrentados ao longo dos anos, mas que serão sanados mediante as técnicas desenvolvidas pelos inúmeros centros de pesquisa embrionárias e seus especialistas. -/- Realização -/- Emanuel Isaque Cordeiro da Silva – Departamento de Zootecnia da UFRPE.

This article analyses some theses developed by John Gardner that deal with the relations between different concepts of responsibility and how these are useful for understanding the relationships between agency, reasons, and responsibility practises. In the first two sections, the text introduces the Aristotelian view developed by John Gardner, focussing on how he understood the relationships between the concepts of basic responsibility, consequential responsibility and prospective responsibility. Sections III. and IV. then review two challenges that arise from the (...) author's treatment of the concept of basic responsibility. The first is the difficulty of understanding some types of responsibility and the second is how we can make sense of the role of excuses in our responsibility practises. Finally, some philosophical tools that Gardner developed in his last works are presented in order to deal with those challenges. / -/- This is a preprint version. (shrink)

In their well-known paper, John Gardner and Stephen Shute (2000) propose a pure case of rape, in which a woman is raped while unconscious and the rape, for a variety of stipulated reasons, never comes to light. This makes the pure case a harmless case of rape, or so they argue. In this paper I show that their argument hinges on an outdated conception of trauma, one which conflates evaluative responses that arise in the aftermath of rape with the (...) non-deliberative somatic responses of a central nervous system to a threatening event. In the first part of this paper, I elaborate this objection by drawing on the neurobiological model of trauma. This gives me an opportunity to illustrate the different ways that rape harms its victims, including the central way, what I call ‘threat-circuitry harm.’ This discussion of trauma invites us to rethink the wrong of rape, and sets the groundwork for my argument, in the second part of the paper, that the wrong of rape consists in its central harm.

Howard Gardner's theory of Multiple Intelligences has had a huge influence on school education. But its credentials lack justification, as the first section of this paper shows via a detailed philosophical analysis of how the intelligences are identified. If we want to make sense of the theory, we need to turn from a philosophical to a historical perspective. This is provided in the second section, which explores how the theory came to take shape in the course of Gardner's (...) intellectual development. The third section looks at changes in the theory since its inception in 1983 and at problems with its applications to education. The paper concludes with a response to Gardner's critical comments on the argument to this point. (shrink)

Despite providing the basic theoretical framework for Western biology and all related sciences, Darwinism continues to be a controversial perspective when it comes to understanding ourselves as distinctly "human." In this paper, I try to correct a common misinterpretation of Thomas Hobbes' conceptualization of human nature which I think sheds light on some of the significant misunderstandings and sources of objection to Darwinism. I begin by contrasting this common misreading of Hobbes' philosophy of human nature with an alternative reading that (...) suggests a more subtle notion than is often allowed. I then summarize the basic ideas of Darwinism and explain why I think a Darwinian conceptualization of humanity, freed from misinterpretations of Hobbes, need not lead to an agonistic or reductive notion of human nature. Suggestions made by the philosophers Charles Taylor and Howard Gardner about how science and philosophy can help or hinder conceptualizations of personhood are considered insofar as they corroborate this idea.

The idea that education should equip people to lead flourishing lives and help others to do so is now becoming salient in policy-making circles. Philosophy of education can help here by clarifying what flourishing consists in. This essay examines one aspect of this. It rejects the view that well-being goods are derivable from human nature, as in the theories of Howard Gardner and Edmond Holmes. It locates them, rather, as cultural products, but not culturally-relative ones, drawing attention to the (...) proliferating forms they have taken over the past three or four centuries. It looks to aesthetics and art criticism as a guide to a philosophical treatment of well-being goods more generally. It also takes off from aesthetics and art criticism in seeking to identify reliable authorities on the flourishing life. On this, it rejects elitist conceptions in favour of a more democratic model, emphasising its importance in education for citizenship. (shrink)

Feyerabend is well-known as a pluralist, and notorious for his defences of, and sympathetic references to, heterodox subjects, such as parapsychology. Focusing on the latter, I ask how we should understand the relationship between the pluralism and the defences, drawing on Marcello Truzzi's and Martin Gardner's remarks on Feyerabend along the way.

From the beginning of the 16th century to the end of the 18th century, there were not less than ten philosophers who focused extensively on Venn’s ostensible analytical diagrams, as noted by modern historians of logic (Venn, Gardner, Baron, Coumet et al.). But what was the reason for early modern philosophers to use logic or analytical diagrams? Among modern historians of logic one can find two theses which are closely connected to each other: M. Gardner states that since (...) the Middle Ages certain logic diagrams were used just in order to teach “dull-witted students”. Therefore, logic diagrams were just a means to an end. According to P. Bernhard, the appreciation of logic diagrams had not started prior to the 1960s, therefore the fact that logic diagrams become an end the point of research arose very late. The paper will focus on the question whether logic resp. analytical diagrams were just means in the history of (early) modern logic or not. In contrast to Gardner, I will argue that logic diagrams were not only used as a tool for “dull-witted students”, but rather as a tool used by didactic reformers in early modern logic. In predating Bernhard’s thesis, I will argue that in the 1820s logic diagrams had already become a value in themselves in Arthur Schopenhauer’s lectures on logic, especially in proof theory.

This paper explores the integration of multiple intelligences and artificial intelligence (AI) in language learning, focusing on its potential to enhance personalization and engagement. Drawing from existing research and studies conducted in various contexts, including the Philippines, this study aims to contribute to the understanding of the benefits, challenges, and effectiveness of this integration. The paper begins with an introduction that highlights the background and significance of integrating multiple intelligences and AI in language learning, identifying research gaps, objectives, research questions, (...) and the theoretical framework. A literature review provides an overview of multiple intelligences theory by Howard Gardner, the role of AI in language learning, and identifies gaps in the existing literature. The methodology section outlines the research design and approach, participant selection, data collection methods, validity and reliability measures, and ethical considerations. Findings and results are presented through the analysis of qualitative data, exploring emergent themes and patterns. The discussion section critically examines the identified research gaps, discusses the validity and reliability of the study, addresses the scope and limitations, and explores the implications of the findings for theory, practice, and future research. The conclusion summarizes the key findings and contributions of the study, reflects on the achievement of research objectives, offers recommendations for further research, and provides final remarks tying together the main points of the study. This paper contributes to the existing body of knowledge by providing insights into the integration of multiple intelligences and AI in language learning and its impact on personalization, engagement, and language learning outcomes.

I argue for a novel understanding of the nature of agent-regret. On the standard picture, agent-regret involves regretting the result of one’s action and thus regretting one’s action. I argue that the standard picture is a flawed analysis of agent-regret. I offer several cases of agent-regret where the agent feels agent-regret but does not regret the result itself. I appeal to other cases where an agent’s attitude towards something depends upon whether or not they are involved in that thing. I (...) argue that the same applies to actions: sometimes an agent’s attitude towards a result differs from their attitude to their involvement in bringing about that result. Agent-regret is regret about my own action, but it need not involve regret about something in the world. I end by considering how this picture of agent-regret allows us to respond to a particular criticism of agent-regret. (shrink)
