Goal-directed spatial decision making video games combine spatial mapping, memory, and reward; all of which can involve hippocampal excitation through suppression of an inhibitory neurotransmitter, γ-aminobutyric acid. In this study, GABA was measured before and after 30 min of video game play within a voxel around the hippocampus. It was predicted that all participants would experience a decrease in GABA during gaming as a result of in-game rewards; and, those who were most competitive with the goal-directed spatial decision making game (...) would display lower hippocampal GABA concentrations after gaming. Those who were not competitive, because they were too skilled or not skilled enough, would demonstrate higher hippocampal GABA concentrations after gaming. While there were no significant differences in hippocampal GABA before and after gaming for gamers and non-gamers alike, there was a significant quadratic regression between performance on a spatial working memory task and post-gaming hippocampal GABA concentrations.

This paper discusses the debate regarding the terms makarios (“blessed”) and eudaimon (“happy”) in Aristotle’s Nicomachean Ethics. In it, I identify two scholarly conclusions regarding these terms: (1) the distinction thesis: that the words mean different things in the text, and (2) the interchangeability thesis: that the words do not mean different things in the text, and may be substituted for one another. I argue that the theories should both be used as heuristic tools of analysis, rather than only one (...) of them being used as a universal rule to be applied to the text. Additionally, I argue that a third heuristic device is needed: I forward that while makarios and eudaimon are sometimes interchangeable (contra the distinction thesis) they are not synonymous (contra the interchangeability thesis). Rather, in some cases, both terms can be translated as “happy,” but they are being used by Aristotle in reference to subjects with distinct natures. In these instances, eudaimonia can sometimes be interpreted as a properly human term, which we cannot apply to the gods. Or, if it is applied to the gods, it must be applied in a distinct, qualified way. Meanwhile, makarios can sometimes be interpreted as a properly divine term, used in reference to the gods or to a god-like status achieved by a human being who has superseded normal human achievement or capacity.

Kelsey Lucyk analyzes how the media and the institution of sport have entrenched certain ideals about masculinity meanwhile reinforcing homophobic attitudes towards gender roles in sports. This article focusses primarily on analyzing Canadian sports and makes use of the concept of muscular Christianity to explain hegemonic masculinity as found in the Canadian institution of sport.

Based on the case report of Nathan Goldstein et al., “But I have a pacer…there is no point in engaging in hypothetical scenarios”: A Non-imminently Dying Patient’s Request for Pacemaker Deactivation, it is reasonable to conclude that it was, all-things-considered, ethically appropriate to grant the patient’s request to deactivate her pacemaker. Philosophically, and as a clinical ethicist, I support the team’s decision to honor the patient’s request for pacemaker deactivation. However, it is worth exploring a bit further whether the distress (...) on the part of the outside hospital’s ethics committee and providers—who declined to honor the patient’s request for pacemaker deactivation—may actually track something of moral significance. In this commentary, I argue that there are reasonable grounds for holding that deactivation of a ‘biofixture’ such as a pacemaker may be more analogous in moral terms to medical aid in dying than it is to standard cases of withdrawal of life support at the end of a patient’s life.

This paper explores differences in national responses to foodborne disease outbreaks, addressing both the sources of policy divergence and their implications for public health and coordinated emergency response. It presents findings from a comparative study of two multi-state E. coli outbreaks, one in the United States and one in Germany, demonstrating important differences in how risk managers understood and responded to each nation’s first major outbreak associated with fresh produce. Drawing on a qualitative analysis of 36 semi-structured interviews with key (...) stakeholders and hundreds of archival documents, this paper traces how social constructions of the E. coli risk interacted with organizational dynamics among state and industry actors to produce divergent policy outcomes: the U.S. outbreak was understood primarily as an agricultural problem that led to an industry-led agricultural solution, whereas the German outbreak was understood as a human disease problem that did not result in a substantial policy response once the acute health crisis passed. The paper concludes by discussing how these policy processes generate partial solutions to foodborne contamination that expose modern societies to systemic vulnerabilities. (shrink)

In his target article, Yarkoni prescribes descriptive research as a potential antidote for the generalizability crisis. In our commentary, we offer four guiding principles for conducting descriptive research that is generalizable and enduring: prioritize context over control; let naturalistic observations contextualize structured tasks; operationalize the target phenomena rigorously and transparently; and attend to individual data.

As the prevalence of conflict and fragility continue to rise around the world, research is increasingly heralded as a solution. However, current ethical guidelines for working in areas suffering from institutional and social fragility, insecurity or violent conflict have been heavily critiqued as highly abstract; focussed only on data collection; detached from the realities of academia in the Global South; and potentially extractive. This article seeks to respond to that assessment by spotlighting some of the most prevalent challenges researchers face (...) in the pursuit of ethical working practices. It explores the material and epistemic injustices that often shape and underpin research structures and relationships in these contexts. The paper draws on the authors’ experiences of research in conflict-affected and fragile contexts over the last fifteen years and on workshop discussions with researchers based in fragile and conflict-affected contexts conducted in Amman, Bogotá and Dhaka in 2019-2020. The paper works from the premise that achieving ethical research in fragile spaces is not dependent solely on activity at the site of research, but also on decisions made across the entire ecosystem of a research project. It therefore interrogates the full research landscape, from funding models, to research design (including research topics, partnerships, methods, participant selection, and researcher positionality), to dissemination plans and ethical gatekeeping. The paper critically reflects on inequities in the processes of knowledge production about conflict and fragility and the key ethical challenges that researchers encounter. It highlights the need for further guidance, support and accountability to ensure ethical research practices. (shrink)

Over the past twenty-five years, thirty-seven states and the US Congress have passed mental health and substance use disorder (MH/SUD) parity laws to secure nondiscriminatory insurance coverage for MH/SUD services in the private health insurance market and through certain public insurance programs. However, in the intervening years, litigation has been brought by numerous parties alleging violations of insurance parity. We examine the critical issues underlying these legal challenges as a framework for understanding the areas in which parity enforcement is lacking, (...) as well as ongoing areas of ambiguity in the interpretation of these laws. We identified all private litigation involving federal and state parity laws and extracted themes from a final sample of thirty-seven lawsuits. The primary substantive topics at issue include the scope of services guaranteed by parity laws, coverage of certain habilitative therapies such as applied behavioral analysis for autism spectrum disorders, credentialing standards for MH/SUD providers, determinations regarding the medical necessity of MH/SUD services, and the application of nonquantitative treatment limitations under the 2008 federal parity law. Ongoing efforts to achieve nondiscriminatory insurance coverage for MH/SUDs should attend to the major issues subject to private legal action as important areas for facilitating and monitoring insurer compliance.

We argue for the importance of looking at the microbiota-gut-brain axis from a human developmental perspective. For this purpose, we first briefly highlight emerging research with infants attesting that the microbiome plays a role in early brain and cognitive development. We then discuss the use of developmentally informed humanized mouse models and implications of microbiome research that go beyond probiotic administration.

Since the fourteenth century, Eastern Woodlands tribes have used delicate purple and white shells called “wampum” to form intricately woven belts. These wampum belts depict significant moments in the lives of the people who make up the tribes, portraying everything from weddings to treaties. Wampum belts can be used as a form of currency, but they are primarily used as a means to record significant oral narratives for future generations. In Reading the Wampum, Kelsey provides the first academic consideration (...) of the ways in which these sacred belts are reinterpreted into current Haudenosaunee tradition. While Kelsey explores the aesthetic appeal of the belts, she also provides insightful analysis of how readings of wampum belts can change our understanding of specific treaty rights and land exchanges. Kelsey shows how contemporary Iroquois intellectuals and artists adapt and reconsider these traditional belts in new and innovative ways. Reading the Wampum conveys the vitality and continuance of wampum traditions in Iroquois art, literature, and community, suggesting that wampum narratives pervade and reappear in new guises with each new generation.

Among all their sensations, agents need to distinguish between those caused by themselves and those caused by external causes. The ability to infer agency is particularly challenging under conditions of uncertainty. Within the predictive processing framework, this should happen through active control of prediction error that closes the action-perception loop. Here we use a novel, temporally-sensitive, behavioural proxy for prediction error to show that it is minimised most quickly when volatility is high and when participants report agency, regardless of the (...) accuracy of the judgement. We demonstrate broad effects of uncertainty on accuracy of agency judgements, movement, policy selection, and hypothesis switching. Measuring autism traits, we find differences in policy selection, sensitivity to uncertainty and hypothesis switching despite no difference in overall accuracy. (shrink)

Aristotle's thesis in Physics I 8 is that a certain old and familiar problem about coming to be can only be solved with the help of the new account of the "principles" he has developed in Physics I 7. This is a strong thesis and the literature on the chapter does not quite do it justice; specifically, as things now stand we are left wondering why Aristotle should have found this problem so compelling in the first place. In this paper (...) I develop an interpretation which will help to remedy this.I believe that Aristotle's problem about coming to be depends on a certain principle to the effect that "nothing can become what it already is" . The main innovation of the interpretation developed here is its suggestion that we understand this principle as a principle about kinds. So understood, the principle does not make the comparatively trivial point that nothing can become any individual it already is, but rather the more powerful and substantive point that nothing can become any kind of thing it already is. I argue that this is a point which Aristotle himself accepts and that this is why the problem about coming to be raises serious difficulties for him. I also discuss Aristotle's proposed solutions to this problem, explaining how each draws on his new account of the principles and why each is required for any full resolution of the difficulties the problem raises. In this way I hope to show how the interpretation developed here does justice to the very strong thesis with which Aristotle begins Physics I 8. I conclude brie fly and somewhat speculatively with a suggestion as to why Aristotle might accept the principle on which I have suggested the problem turns. (shrink)

Aristotle introduces Physics I as an inquiry into principles; in this paper I ask where he argues for the position he reaches in I 7. Many hold that his definitive argument is found in the first half of I 7 itself; I argue that this view is mistaken: the considerations raised there do not form the basis of any self-standing argument for Aristotle's doctrine of principles, but rather play a subordinate role in a larger argument begun in earnest in I (...) 5. This larger argument stalls in I 6, which ends in aporta; I argue that the problem lies in the fact that Aristotle's reasoning in I 6 thoroughly undermines his reasoning in I 5 (on which I 6 is ostensibly supposed to build). I further argue that the materials necessary for resolving this problem, and thereby allowing the argument begun in I 5 to reach its proper conclusion, are supplied by the thesis that organizes the first half of I 7. Along the way I offer some remarks about Aristotle's doctrine of principles, arguing that it is about the principles of natural substance (as opposed to coming to be or change). I also offer some remarks about the thesis which organizes the first half of I 7.1 argue negatively that it is not anything like a preliminary statement of Aristotle's doctrine of principles. I argue positively that it reflects Aristotle's idea that there are two distinct kinds of effect change has upon things (one constructive, the other destructive). One of these effects lies behind Aristotle's reasoning in I 5, the other comes to the fore in 16; the achievement of the first half of I 7 is to reconcile these seemingly competing conceptions by finding a place for them both in a unified account of coming to be and its subjects.

Musical life became disrupted in 2020 due to the COVID-19 pandemic. Many musicians and venues turned to online alternatives, such as livestreaming. In this study, three livestreamed concerts were organized to examine separate, yet interconnected concepts—agency, presence, and social context—to ascertain which components of livestreamed concerts facilitate social connectedness. Hierarchical Bayesian modeling was conducted on 83 complete responses to examine the effects of the manipulations on feelings of social connectedness with the artist and the audience. Results showed that in concert (...) 1, where half of the participants were allowed to vote for the final song to be played, this option did not result in the experience of more agency. Instead, if their preferred song was played (regardless of voting ability) participants experienced greater connectedness to the artist. In concert 2, participants who attended the concert with virtual reality headsets experienced greater feelings of physical presence, as well as greater feelings of connectedness with the artist, than those that viewed a normal YouTube livestream. In concert 3, attendance through Zoom led to greater experience of social presence, but predicted less connectedness with the artist, compared to a normal YouTube livestream. Crucially, a greater negative impact of COVID-19 (e.g., loneliness) predicted feelings of connectedness with the artist, possibly because participants fulfilled their social needs with this parasocial interaction. Examining data from all concerts suggested that physical presence was a predictor of connectedness with both the artist and the audience, while social presence only predicted connectedness with the audience. Correlational analyses revealed that reductions in loneliness and isolation were associated with feelings of shared agency, physical and social presence, and connectedness to the audience. Overall, the findings suggest that in order to reduce feelings of loneliness and increase connectedness, concert organizers and musicians could tune elements of their livestreams to facilitate feelings of physical and social presence.

The authors of the feature article argue against implied consent in all episiotomy cases, but allow that opt-out consent might be appropriate in limited circumstances.1 However, they do not indicate how clinicians should assess whether the pregnant person is capable of consenting in this way during an obstetric emergency. This commentary will focus on how capacity should be determined during these circumstances, suggest next steps for clinicians if capacity is deemed uncertain or absent, and discuss the appropriate role for opt-out (...) consent in labour. Previous studies investigating the extent to which pregnant persons retain decision-making capacity during labour have shown poor recall, a component of capacity, about consent processes during obstetric emergency procedures in 14%–49% of cases.1 2 As the feature article acknowledges, this does not mean that pregnant persons should be assumed to lack decision-making capacity during labour. Although pain, labour intensity, exhaustion and medications can make consenting processes during labour more difficult and it is possible that these factors will result in the impaired ability of the pregnant person to make informed and voluntary decisions about treatment options, this possibility of impaired capacity should not be taken as the expected outcome nor should it be used as an excuse to skip consenting procedures.1 2 The default to treat labouring patients as able to make their own decisions still stands, although signs that a person lacks ….

A wide range of countries decided to go into lockdown to contain the coronavirus disease (COVID-19) pandemic of 2020, a setting separating people and restricting their movements. We investigated how musicians dealt with this sudden restriction in mobility. Responses of 234 people were collected. The majority of respondents (95%) resided in Belgium or the Netherlands. Results indicated a decrease of 79% of live music making in social settings during lockdown compared with before lockdown. In contrast, an increase of 264% was (...) demonstrated for online joint music making. However, results showed that most respondents were largely or even completely unaccustomed with specialized platforms for online joint music making (e.g., JamKazam, Jamulus). Respondents reported to mostly use well-known video-conferencing platforms such as Zoom and Skype when playing together virtually. However, when such video-conferencing platforms were used, they were often not employed for synchronized playing and were generally reported to insufficiently deal with latency issues. Furthermore, respondents depending on music making as their main source of income explored online real-time methods significantly more than those relying on other income sources. Results also demonstrated an increase of 93% in the use of alternative remote joint music-making methods (e.g., recording parts separately and subsequently circulating these digital recordings). All in all, results of this study provide a more in-depth view on joint music making during the first weeks of lockdown induced by the COVID-19 pandemic of 2020, and demonstrate users’ perceptions of performance and usability of online real-time platforms as well as alternative methods for musical interaction.

Anxiety disorders are one of the most prevalent mental disorders globally, and 63% of those diagnoses are of women. Although widely acknowledged across health disciplines and news and social media outlets, the majority of attention has left assumptions underlying women's anxiety in the twenty-first century unquestioned. Drawing on my own experiences of anxiety, I will the explore both concept and diagnosis in the Western world. Reflecting on my own experiences through a critical feminist lens, I will investigate the construction of (...) anxiety as mental disorder in the context of neoliberal late-stage capitalism, heteropatriarchy, and biomedical psychiatry. Tracing the postpositivistic foundations of anxiety, as well as the historical and ongoing medicalization and pathologization of women, I will critically consider the sociopolitical implications of constructing anxiety as biomedical disorder. Assumptions underlying mental health will be explored within the context of the construction, experience, and operationalization of gender and the way gender intersects with diverse positionalities, power, knowledge, and neoliberal governance. Weaving the voices of women poets with the biomedical language of disorder, this critical-realist inquiry will explore my anxiety as it relates to the epidemic levels of anxiety among other women, and the late-stage capitalist world within which anxiety flourishes.

The role of chance in producing a picture by snapping a shutter release before a complex and quickly changing scene weakens the bond between the historic action photograph and the meanings it is routinely asked to bear. To appreciate this problem and to understand the array of popular notions that have been marshaled to finesse or suppress the role of chance in photographic production, I consider the case of Joe Rosenthal’s 1945 photograph of American servicemen raising a flag on Iwo (...) Jima. The analysis pushes the production of this famous photograph through a series of zoological analogies: Is it like a fisherman reeling in a trophy catch? Like a cat pouncing on a mouse or a spider setting a trap for a fly? Like a pig pushing its snout through the dirt? Like chimpanzees banging at typewriters? These analogies are playful but also serious. We need new models for understanding the production of the historic action photograph because the predominant modern and postmodern approaches to that production have suppressed the role of chance. Whereas the modern regime tends to understand the historic action photograph as an inspired flash of history, the postmodern regime tends to understand it as a discursive effect. Entertaining the notion that such a photograph is instead a stochastic result leads to a new conception of photography and its relationship to history. Chance emerges as a third kind of photographic madness, alongside the industrial madness decried by Charles Baudelaire and the indexical madness that moved Roland Barthes. (shrink)

Abstract:There is a storied history of Native and Indigenous feminisms on Turtle Island (North America). We are fortunate that many of those stories birthed from an ancestral tradition of storytelling and survivance were captured in the canonical feminist anthology This Bridge Called My Back: Writings of Radical Women of Color. In celebration and commemoration of 40 years since This Bridge was first published we visit with three of the books original Native and Indigenous contributors–Chrystos, Max Wolf Valerio, and Jo Carrillo–to (...) recount old as well as new stories as they explore what Native and Indigenous feminisms mean to them and their continued work for Indigenous visibility. The conversation provides a unique intergenerational vision for conceptualizing contemporary Native and Indigenous feminisms all the while building upon the legacy and path set forth by amazing Native and Indigenous women trailblazers.

Hobbs (2010) introduced ‘clause-internal coherence’ (CIC) to describe inferences in, e.g., ‘A jogger was hit by a car,’ where the jogging is understood to have led to the car-hitting. Cohen & Kehler (2021) argue that well-known pragmatic tools cannot account for CIC, motivating an enrichment account familiar from discourse coherence research. An outstanding question is how to compositionally derive CIC from coherence relations. This paper takes strides in answering this question. It first provides experimental support for the existence of CIC (...) via offline evidence that attributive (non-)deverbal adjectives can trigger the same causal inferences within clauses that their predicative counterparts can trigger across clauses, albeit more weakly. To explain the experimental results, we use tools in Segmented Discourse Representation Theory (SDRT), which allows us to show that causal inferences can be derived in various ways, depending on whether deverbal adjectives are used attributively or predicatively. If the former, they are presupposition triggers and the coherence relations Elaboration/Continuation compete with Background; if the latter, Explanation/Result compete with Background. These different competitions -- cashed out in terms of interaction between default axioms -- correlate with the difference in the relative salience of the causal inferences. (shrink)

My intention in writing this article is to illustrate how I engage with the process of orienting to the meaning of pedagogy by inquiring into several moments in my life where I am able to fully experience its um. I begin this phenomenological inquiry by plunging into my experience on a teeter-totter as a young child, and use the sense of ups and downs as a metaphor for the tensions of weight and weightlessness, comfort and challenge that characterize the pedagogical (...) world. I then attempt to gain a more perceptual understanding of pedagogy by narrowing in on the suspended moment, which becomes a metaphor for the pedagogical moments of support, vulnerability, and opening that emanate from this tension. In these particular moments, I am able to dwell in the spaces in-between my everyday ups and downs and become existentially conscious and pedagogically connected to the world around me. By metaphorically connecting each of these moments to my teeter-totter experience, I illustrate how embracing the tensions of life and allowing myself to dwell in a suspended moment, deepens my perceptual understanding of pedagogy and influences my current pedagogical practice as a new teacher and master’s student.

We conducted a set of experiments to compare the effect of ambiguity in single-person decisions and games. Our results suggest that ambiguity has a bigger impact in games than in ball and urn problems. We find that ambiguity has the opposite effect in games of strategic substitutes and complements.

In addition, we note that subjects’ ambiguity attitudes appear to be context dependent: ambiguity loving in single-person decisions and ambiguity averse (...) in games.

As traditional patronage gave way to new markets in the modern period, artists went in search of a public.

Transcriptome sequencing has identified more than a thousand potentially imprinted genes in the mouse brain. This comes as a revelation to someone who cut his teeth on the identification of imprinted genes when only a handful was known. Genomic imprinting, an epigenetic mechanism that determines expression of alleles according to sex of transmitting parent, was discovered over 25 years ago in mice but remains an enigmatic phenomenon. Why do these genes disobey the normal Mendelian logic of inheritance, do they function (...) in specific processes, and how is their imprinting conferred? Next generation sequencing technologies are providing an unprecedented opportunity to survey the whole genome for imprinted genes and are beginning to reveal that imprinting may be more pervasive than we had come to believe. Such advances should lay the foundation for a definitive account of imprinting, but may also challenge accepted views on what it means to be imprinted.Editor's suggested further reading in BioEssays RNA as the substrate for epigenome‐environment interactions Abstract.

Many autistic behaviours can rightly be classified as adaptive, but why these behaviours differ from adaptive neurotypical behaviours in the same environment requires explanation.

Why is the human mind able to perceive and understand the truth about reality; that is, why does it seem to be the mind's specific function to know the world? Sean Kelsey argues that both the question itself and the way Aristotle answers it are key to understanding his work De Anima, a systematic philosophical account of the soul and its powers. In this original reading of a familiar but highly compressed text, Kelsey shows how this question underpins (...) Aristotle's inquiry into the nature of soul, sensibility, and intelligence. He argues that, for Aristotle, the reason why it is in human nature to know beings is that 'the soul in a way is all beings'. This new perspective on the De Anima throws fresh and interesting light on familiar Aristotelian doctrines: for example, that sensibility is a kind of ratio, or that the intellect is simple, separate, and unmixed.

Life-saving health resources like organs for transplant and experimental medications are persistently scarce. How ought we, morally speaking, to ration these resources? Many hold that, in any morally acceptable allocation scheme, the young should to some extent be prioritized over the old. Govind Persad, Alan Wertheimer and Ezekiel Emanuel propose a multi-principle allocation scheme called the Complete Lives System, according to which persons roughly between 15 and 40 years old get priority over younger children and older adults, other things being (...) equal. They defend this ‘modified youngest first’ principle in part by appealing to the greater social investment that has been made in 15-year-olds than in younger children. Ruth Tallman has proposed a distinctive defense of modified youngest first, one that appeals not at all to social investment. We find this defense wanting. Tallman’s argument depends on the idea, which we try to show to be implausible, that allocations should maximize the number of people in the midst of a possibly complete life who actually complete their lives. Moreover, Tallman does not justify the priority modified youngest first gives 15-year-olds over, for example, 5-year-olds. Tallman fails to dispel a serious shortcoming with modified youngest first: its fundamental unfairness to pre-adolescents. (shrink)

Differing worldviews give interdisciplinary work value. However, these same differences are the primary hurdle to productive communication between disciplines. Here, we argue that philosophical issues of metaphysics and epistemology subserve many of the differences in language, methods and motivation that plague interdisciplinary fields like educational neuroscience. Researchers attempting interdisciplinary work may be unaware that issues of philosophy are intimately tied to the way research is performed and evaluated in different fields. As such, a lack of explicit discussion about these assumptions (...) leads to many conflicts in interdisciplinary work that masquerade as more superficial issues. To illustrate, we investigate how philosophical assumptions about the mind may influence researchers in educational neuroscience. The methods employed by researchers in this field are shaped by their metaphysical beliefs, and arguments around these issues can threaten accepted disciplinary ontologies. Additionally, how a researcher understands reduction in the special sciences and how they place their colleagues in this ontology constrains the scope of interdisciplinary projects. In encouraging researchers to explicitly discuss the philosophical assumptions underlying their research we hope to alleviate some of the conflict and establish realistic expectations for collaborative projects.

This paper addresses a dichotomy in the attitudes of some clinicians and bioethicists regarding whether there is a moral difference between deactivating a cardiac pacemaker in a highly dependent patient at the end of life, as opposed to standard cases of withdrawal of treatment. Although many clinicians hold that there is a difference, some bioethicists maintain that the two sorts of cases are morally equivalent. The author explores one potential morally significant point of difference between pacemakers and certain other life-sustaining (...) treatments: specifically, that the former are biofixtures, which become part of the patient in a way that the latter do not. The concept of the pacemaker as biofixture grants pacemakers a unique moral status that gives reason to treat a pacemaker the same as other parts of the patient that are necessary to sustain life. The author employs this biofixture analysis to affirm the intuition that deactivating a pacemaker in a highly dependent patient at the end of life is, in moral terms, more analogous to active euthanasia than it is to standard cases of withdrawal of treatment. The paper concludes with consideration of potential implications for further implantable medical technologies, such as ventricular assist devices and total artificial hearts. (shrink)

When Cicero examines the varied versions of cradle arguments that appear in De finibus, he finds much to criticize. Though he rejects these attempts to discern our proper ethical ends from the earliest inclinations of newborn animals, he nevertheless accepts that human beings should adopt ends for themselves that are consistent with, and perfections of, human nature. I argue that Cicero uses two connected argumentative strategies to create an appeal to nature that overcomes some basic problems he has with the (...) cradle arguments used in Epicureanism, Stoicism, and the Old Academy. The first strategy criticizes the different cradle arguments directly, by which Cicero establishes two negative criteria for any appeal to nature. These criteria indicate what to avoid in arguing for a highest moral end or summum bonum. These criteria eliminate the Epicurean and Stoic cradle arguments, and more subtly criticizes the Antiochian one. As a result, it may seem plausible that Cicero either adopts the Antiochian position himself or that he at least considers it to be a strong position that is worthy of further consideration, particularly in contrast with his categorical rejection of the other schools. Cicero’s second strategy, however, leads us away from accepting any established cradle argument, including the Antiochian one. This strategy develops a rich theme of education over the course of the text and emphasizes an appeal to the telic sense of “nature” that ultimately meets the two criteria set out by his first strategy. He does not seek ethical direction in some biological origin and given nature as cradle arguments do. Cicero appeals instead to human nature and its summum bonum as it appears during philosophical education. Though he finds cradle arguments rely too much on given nature and too little on telic nature, Cicero’s own own emphasis on education and telic nature amounts to a new appeal to “nature” that, in avoiding the “cradle”, is more sound than those of his philosophical rivals.
