This is an introductory blog to the question: "What is a human being?".

This article contributes to the debate on the relation between Aristotle’s practical and theoretical philosophy. It argues that his practical philosophy depends to a considerable extent on his teleological conception of nature. This thesis is primarily directed against scholars who maintain that Aristotle does not derive political and human relations from natural or cosmic conditions. The paper defends David Sedley’s anthropocentric interpretation of Aristotle’s natural teleology and shows how Aristotle applies teleological explanations to power relations among human beings – among (...) men and women and among freemen and natural slaves – and their purposes and goals. The article focuses on Aristotle’s human ‘function’ (ergon) argument, which is a teleological argument at the centre of his practical philosophy. It argues that this argument, which Aristotle presents to define ‘human flourishing’ or ‘happiness’ (eudaimonia), depends on his definition of man as the only ‘living being that has language and reason’ (zôon logon echon). It further claims that the dispute about whether Aristotle identifies eudaimonia only with a life of contemplation or whether eudaimonia includes a political life can be clarified by referring to the natural purpose of logos.

Este artigo contribui para o debate sobre a relação da filosofia prática e teórica de Aristóteles. Ele argumenta que sua filosofia prática depende em grande parte de sua concepção teleológica da natureza. Esta tese é dirigida principalmente contra os estudiosos que sustentam que Aristóteles não deriva de relações políticas e humanas de condições naturais ou cósmicas. O artigo defende a interpretação antropocêntrica de David Sedley da teleologia natural de Aristóteles e mostra como Aristóteles aplica explicações teleológicas às relações de poder (...) entre os seres humanos - entre homens e mulheres e entre homens livres e escravos naturais - e seus propósitos e objetivos. O artigo enfoca o argumento da “função” (ergonomia) humana de Aristóteles, que é um argumento teleológico no centro de sua filosofia prática. Argumenta que este argumento, que Aristóteles apresenta para definir ‘florescimento humano’ ou ‘felicidade’ (eudaimonia), depende de sua definição de homem como o único ‘ser vivo que tem linguagem e razão’ (zôon logon echon). Alega ainda que a disputa sobre se Aristóteles identifica eudaimonia apenas com uma vida de contemplação ou se eudaimonia inclui uma vida política pode ser esclarecida referindo-se ao propósito natural dos logotipos.

The relationship between animal rights and contractarian theories of justice such as that of Rawls has long been vexed. In this article, I contribute to the debate over the possibility of inclusion of animals in Rawls’s theory of justice by critiquing the rationale he gives for their omission: that they do not possess moral personality. Contrary to Rawls’s assumptions, it appears that some animals may possess the moral powers that comprise moral personality, albeit to a lesser extent than (...) most humans. Some animals can act in pursuit of preferences and desires (and communicate them non-verbally), which might be taken as implicitly selecting a conception of the good; further, scientific research demonstrating inequity aversion and social play behaviors suggests that some animals can have a sense of justice relating to their own social groups. I conclude that Rawls’s theory needs to acknowledge any animals that can be considered to meet the threshold of moral personality, while the concept of moral personality as a range property may also require reconsideration.

Recent decades have witnessed the rise of chefs to a position of cultural prominence. This rise has coincided with increased consciousness of ethical issues pertaining to food, particularly as they concern animals. We rank cookbooks by celebrity chefs according to the minimum number of sentient animals that must be killed to make their recipes. On our stipulative definition, celebrity chefs are those with their own television show on a national network in the United States, the United Kingdom, Canada or Australia. (...) Thirty cookbooks by 26 such chefs were categorized according to the total number of cows, pigs, chicken, fish and other species they included as ingredients. The total number of animals killed was divided by the number of non-dessert recipes to generate an average number of animal deaths per recipe for each book. We outline the rationale for our project and its methodology before presenting a ranked table of 30 cookbooks by celebrity chefs. This method generates several interesting findings. The first concerns the wide variation in animal fatalities among cookbooks. The chef with the heaviest animal footprint killed 5.25 animals per recipe, while the omnivorous chef with the smallest footprints killed 0.19 per recipe. Clearly, not all approaches to meat eating are equal when it comes to their animal mortality rate. Pigs and large ruminants are all substantially bigger than poultry, which are themselves bigger than many fish. The prime determinant of a chef’s place in the index was the number of small animals his or her recipes required. Whether a chef cooked in the style of a particular cuisine (Italian, French, Mexican etc.), by contrast, had no discernible influence on his or her ranking. We analyze how different chefs present themselves—as either especially sensitive or insensitive to ethical issues involving animals and food—and note cases where these presentations do or do not match their index ranking. -/- .

New discoveries are improving the odds of human cells surviving in host animals, prompting regulatory and funding agencies to issue calls for additional layers of ethical oversight for certain types of human–animal chimeras. Of interest are research proposals involving chimeric animals with humanized brains. But what is motivating the demand for additional oversight? I locate two, not obviously compatible, motivations, each of which provides the justificatory basis for paying special attention to different sets of human–animal chimeras. Surprisingly, the (...) sets of animals that actually get flagged for special scrutiny by research and funding guidelines do not correlate with either of the sets of animals that arise when we think about what is motivating additional oversight. What this shows is that existing research policies and funding guidelines are disconnected from their motivation: the rationale for flagging certain types of human–animal chimeras as requiring special oversight is ignored in execution.

As rational animals, human beings not only have the ability to think but also the capacity to understand. Human rationality, so to speak, is constituted by thinking and understanding. The immediate connotation of rationality, however, is almost always thinking. Hence to speak of man as an animal rationale is to speak of man as a thinking being. But following his mentor Martin Heidegger, Hans-Georg Gadamer insists that man does not only think, but most importantly understands. To understand is (...) an essential part of being human, of being rational. But what is understanding? What does it mean to understand? The issue of human understanding is not something simply epistemological; rather, it is something hermeneutical. That is to say, understanding always relates to the act of interpretation. In his monumental work Truth and Method, Gadamer diligently considers the matter of human understanding from a purely hermeneutical perspective. This paper, then, aims to synthesize Gadamer's hermeneutical theory and argues that for Gadamer, human understanding is essentially characterized by a kind of textual intercourse, that is, a dialogic interaction or an intimate exchange of horizons between an interpreting subject and a text which, in very broad terms, can refer to any object of interpretation.

When does it make sense to act randomly? A persuasive argument from Bayesian decision theory legitimizes randomization essentially only in tie-breaking situations. Rational behaviour in humans, non-human animals, and artificial agents, however, often seems indeterminate, even random. Moreover, rationales for randomized acts have been offered in a number of disciplines, including game theory, experimental design, and machine learning. A common way of accommodating some of these observations is by appeal to a decision-maker’s bounded computational resources. Making this suggestion both precise (...) and compelling is surprisingly difficult. Toward this end, I propose two fundamental rationales for randomization, drawing upon diverse ideas and results from the wider theory of computation. The first unifies common intuitions in favour of randomization from the aforementioned disciplines. The second introduces a deep connection between randomization and memory: access to a randomizing device is provably helpful for an agent burdened with a finite memory. Aside from fit with ordinary intuitions about rational action, the two rationales also make sense of empirical observations in the biological world. Indeed, random behaviour emerges more or less where it should, according to the proposal. (shrink)

In this transdisciplinary perspective, I present my initial ecospiritual thinking about the COVID-19 pandemic in a poem, titled Her Parasites. I identify with other thinkers – both those in science and not – who articulated ecophilosophical musings about the pandemic in various ways, some of whom were met with mockery and censure. In the hope that it will inspire openness and a sense of curiosity, I draw on metaphysical insights from Vedic treatises and the literature on environmental decline, zoonotic epidemiology, (...) health science, animal agriculture, animal ethics, and animal sentience to explain my poem’s philosophical and ecological framework. I focus on the scientific knowledge of epidemics caused by viruses that transcend species boundaries, why cross-species hopping occurs, and the nature (and incredible intelligence) of such viruses. I invite readers to consider ancient Vedic principles that articulate the rationale for living harmoniously with other sentient beings and entities. Considering the unseen metaphysical association between the pandemic and animal cruelty explained through the Vedic laws of Karmā, I present the possibility that one of the lessons Mother Earth might have wanted the Homo sapiens species to learn from the COVID-19 pandemic is its need to alter its diet. I end with a discussion on the possibility and value of this change. The downplaying or denial of animal sentience (strategies to overcome the psychological discomfort of incongruence between loving animals and eating them, as described in social psychology), is a barrier to this change. However, observed through a Vedic lens, this cognitive dissonance suggests that the Homo sapiens species is innately humane, the realisation of which might hold the key to this dietary change.

Throughout history, dogmatists and sceptics of various branches have been inclined to agree on the description of man as a 'filaletes zoon' - a 'truth-loving animal' as Sextus Empiricus had defined him - on the fact that 'the desire to know is innate in man' and on interpreting this as the ideal force inspiring the search for knowledge. The two parties have, however, always dissented considerably about the consequences to be drawn from such a vision of man as (...) a knowledge-seeker. This paper seeks to clarify the discrepancies occurring between the sceptical and the dogmatic understanding of man's epistemophilics impulse, through first using the metaphysical argument ex communi omnium sciendi desiderio proposed by Pierre de Villemandy in his Scepticismus Debellatus, and then Cicero's more sceptical and purely anthropological reading of the characterization of man as a knowledge-seeker. The paper then goes on to discuss the salient features that in different times and manners have characterized the philosophical debate on the topic. (shrink)

Support for the biological concept of race declined slowly but steadily during the second half of the twentieth century. However, debate about the validity of the race concept has recently been reignited. Genetic-clustering studies have shown that despite the small proportion of genetic variation separating continental populations, it is possible to assign some individuals to their continents of origin, based on genetic data alone. Race naturalists have interpreted these studies as empirically confirming the existence of human subspecies, and by extension (...) biological races. However, the new racial naturalism is not convincing. The continental clusters appealed to by race naturalists are arbitrary and superficial groupings, which should not be elevated to subspecies status. Moreover, the criteria applied to humans are not consistent with those used to define subspecies in nonhuman animals, and no rationale has been given for this differential treatment. (shrink)

There is a certain metaphor that has enjoyed tremendous longevity in the evolution of ageing literature. According to this metaphor, nature has a certain goal or purpose, the perpetuation of the species, or, alternatively, the reproductive success of the individual. In relation to this goal, the individual organism has a function, job, or task, namely, to breed and, in some species, to raise its brood to maturity. On this picture, those who cannot, or can no longer, reproduce are somehow invisible (...) to, or even dispensable to, the evolutionary process. Here, I argue that the metaphor should be discarded, not on the grounds that it is a metaphor, but on the grounds that this particular metaphor distorts our understanding of the evolution of ageing. One reason the metaphor is problematic is that it frames senescence and death as nature’s verdict on the value of older individuals. Instead, we should explore a different metaphor: the lengthy post-reproductive period in humans and some other animals is not an accident of culture, but designed by nature for the purpose of supporting and guiding younger generations. On this alternate picture, different stages of life have their own evolutionary rationales, their distinctive design features, their special mandates. (shrink)

Aristotle’s Politicsis not only famous for its theory of constitutions, but for its statements about human nature. According to the central claim of Aristotle’s political anthropology, man is by nature a political animal (phusei politikon zôon). This famous statement is presented as the conclusion of the first set of arguments that Aristotle develops in the second chapter of book I of the Politics(Pol.,I, 2, 1252a24–1253a3). Aristotle’s statement is inextricably linked with the claim that the polisexists by nature (phusei), which (...) he mentions in the same phrase, as part of his conclusion: “From these considerations it is evident that the polisis one of the things that exist by nature, and that man is by nature a political animal”(Pol.,I, 2, 1253a1–3). Evidently, the claims that the polisexists by nature and that man is by nature a political animal are complementary. This article presents an interpretation of the two complementary claims or theses arguing that in Pol.,I, 2 Aristotle conceives exclusively of human beings as political animals because the whole chapter focuses on theanalysisof the polis,a community peculiar to humans. Italso examines Aristotle’sclaim that the polis“is by nature prior (proteron) to the household and to the individual”(Pol.,I, 2, 1253a18–19). The paperdisagrees withscholars whounderstand this claim as an independent third thesis and theoremand argues that Aristotle’s claim functions as a strong argument for the thesis that man is by nature a political animal. Furthermore, it contends thatAristotle neither defends an organic theory of the polisnor has a “tendency towards totalitarianism”(J. Barnes). -/- . (shrink)

Freeganism is the practice of eating food that is free. It is commonly associated with recovering food that grocery stores and restaurants have thrown away, but vegetables grown in one’s garden and other free foods, such as leftovers from a work event, would also qualify. It is worth asking whether there is a form of freeganism that can be justified in new omnivorist terms. Could it be consistent with animal protection to eat meat, just so long as we don’t (...) pay for it? -/- I argue that from an animal protection point of view, freegan meat consumption faces two difficulties. The first is that when it involves the consumption of animal flesh conventionally regarded as edible (chicken, pork, beef, etc.) but not other types of flesh commonly considered inedible (mice, dogs, etc.), the practice is likely to be rooted in speciesism. This runs contrary to new omnivorism’s own principles, which are anti-speciesist. In addition, when the meat in question is the product of animal agriculture, consuming it will amount to a form of complicity in the industry’s wrong-doing, as the rationale for the animal’s slaughter will be retroactively endorsed. Either of these two considerations taken by itself will suffice to generate a presumption against freegan meat consumption. -/- My analysis, however, does not address every conceivable defense of freegan meat consumption. In particular, neither consideration generates a reason to avoid all animal by-products, such as eggs from backyard chickens that are well cared for. But given that the by-products in question will not be industrially produced, such consumption is likely to be permissible only in exceptional instances, rather than a practice available to society at large.

In recent years, there has been a heated debate about how to interpret findings that seem to show that humans rapidly and automatically calculate the visual perspectives of others. In the current study, we investigated the question of whether automatic interference effects found in the dot-perspective task (Samson, Apperly, Braithwaite, Andrews, & Bodley Scott, 2010) are the product of domain-specific perspective-taking processes or of domain-general “submentalizing” processes (Heyes, 2014). Previous attempts to address this question have done so by implementing inanimate (...) controls, such as arrows, as stimuli. The rationale for this is that submentalizing processes that respond to directionality should be engaged by such stimuli, whereas domain-specific perspective-taking mechanisms, if they exist, should not. These previous attempts have been limited, however, by the implied intentionality of the stimuli they have used (e.g. arrows), which may have invited participants to imbue them with perspectival agency. Drawing inspiration from “novel entity” paradigms from infant gaze-following research, we designed a version of the dot-perspective task that allowed us to precisely control whether a central stimulus was viewed as animate or inanimate. Across four experiments, we found no evidence that automatic “perspective-taking” effects in the dot-perspective task are modulated by beliefs about the animacy of the central stimulus. Our results also suggest that these effects may be due to the task-switching elements of the dot-perspective paradigm, rather than automatic directional orienting. Together, these results indicate that neither the perspective-taking nor the standard submentalizing interpretations of the dot-perspective task are fully correct. (shrink)

Europe has never had a single definition for the term ‘citizen.’ Indeed, over the centuries the significance of this term has undergone far-reaching evolution. In different historical periods, different states, and different European languages, this term has had diverse meanings and has been used in varying contexts. The concept of ‘citizen’ has repeatedly been defined anew depending upon specific political, social, and economic conditions. At various periods, the term ‘citizen’ has related to a wider or narrower portion of a given (...) state’s society. The criteria by which an individual was said to form a part of the body of citizens have also differed. The changes which have taken place in the definition of a ‘citizen’ over the centuries are enormous. This is not to say, however, that there has been no common core to the concept of citizen as it has taken shape over the course of hundreds of years. As far back as ancient times, a member of the state could influence the shaping of that state’s authorities and could participate in government. It is the Aristotelian concept of the citizen – a concept that has influenced all historical models of citizenship since – which is at the root of the citizen understood as a political animal (politikon zoon). In addition, personal freedom has always been a sine qua non for possessing citizen status. Thus, a citizen has always been, and remains, the opposite of a slave. It has also come to be accepted that citizenship implies the primacy of an individual’s rights in a state over an individual’s obligations to that state. The polar opposite of this situation in the historical dimension is subjection to the monarch in an absolute monarchy. Thus the ‘citizen’ also stands in opposition to the ‘subject.’ When speaking of the historical models containing the said ‘citizenship traits’ of a person’s status in the state, we usually refer to the model of the citizen in ancient times, in medieval municipal citizenship, and in modern times, in the fully−formed nation-state. It is difficult to imagine a citizen in an absolute monarchy, and in a world of subjection. Still, it is possible to give rein to one’s imagination and perceive citizens in such a setting; one could even go a step further and call the subject of an absolute monarch a citizen. But is imagination truly necessary in order to conduct such a seemingly obvious reversal of perspective?

Placebos are often used by clinicians, usually deceptively and with little rationale or evidence of benefit, making their use ethically problematic. In contrast with their typical current use, a provocative line of research suggests that placebos can be intentionally exploited to extend analgesic therapeutic effects. Is it possible to extend the effects of drug treatments by interspersing placebos? We reviewed a database of placebo studies, searching for studies that indicate that placebos given after repeated administration of active treatments acquire (...) medication-like effects. We found a total of 22studies in both animals and humans hinting of evidence that placebos may work as a sort of dose extender of active painkillers. Wherever effective in relieving clinical pain, such placebo use would offer several advantages. First, extending the effects of a painkiller through the use of placebos may reduce total drug intake and side effects. Second, dose-extending placebos may decrease patient dependence. Third, using placebos along with active medication, for part of the course of treatment, should limit dose escalation and lower costs. Importantly, provided that nondisclosure is pre-authorized in the informed consent process and that robust evidence indicates therapeutic benefit comparable to that of standard full-dose therapeutic regimens, introducing dose-extending placebos into the clinical arsenal should be considered. This novel prospect of placebo use has the potential to change our general thinking about painkiller treatments, the typical regimens of painkiller applications, and the ways in which treatments are evaluated.

In this paper, I consider Ripstein and Dan-Cohen's critiques of the 'harm principle'. Ripstein and Dan-Cohen have asserted that the harm principle should be jettisoned, because it allegedly fails to provide a rationale for criminalising certain harmless wrongs that ought to be criminalised. They argue that Kant's second formulation of the categorical imperative and his concept of 'external freedom' are better equipped for ensuring that criminalisation decisions meet the requirements of fairness. Per contra, I assert that Kant's deontological theory (...) is about identifying morally wrongful and rightful conduct: it does not tell the legislature which of those wrongs justify a criminal law response in accordance with the requirements of fairness and justice. Some wrongdoers deserve censure and the stigma that results from criminalisation, but others do not. Kant's deontological theory does not limit the scope of the criminal law merely to those wrongs that deserve a criminal law response. Fair and principled criminalisation requires more than mere wrongdoing. I assert that it is only fair to criminalise wrongs when further normative reasons can be invoked to justify the use of the criminal law as a means for deterring the unwanted conduct. While 'harm to others' is not the only normative reason that can be used to demonstrate that it is fair to criminalise a given act, it is the justification that has the greatest reach. It would not be fair to criminalise mere wrongdoing (that is, every violation of freedom: trespass to goods etc. or every violation of the categorical imperative: every false promise etc.). Nor is it possible to distinguish one violation of freedom from the next, as freedom is not measurable. Thus, murder and trespass to goods would be equally wrong and equally criminalisable in Kant's scheme. A further problem with Dan-Cohen's use of the second formulation of Kant's categorical imperative is that it aims to be an inclusive criterion for identifying conduct that is prima facie criminalisable, but this inclusive approach does not explain the wrongfulness (or in Dan-Cohen's use of the categorical imperative the criminalisableness) of harming animals. In this paper, I demonstrate that the harm principle is able to meet the challenges raised by Ripstein and Dan-Cohen. I also demonstrate that it offers superior criteria for ensuring that criminalisation decisions are fair, just and principled than is offered by Kant's deontological theory. (shrink)

Some people believe that critical thinking is not a modern science, but its roots are old and deeply rooted in the history of philosophy. Its roots date back to Aristotle, the inventor of logic and who was called the first teacher by virtue of this invention. Aristotle was impressed by the language of mathematics and wanted to invent a language to logic similar to the language of Mathematics. What encouraged Aristotle to do so is that Math language is quite different (...) from daily life language. For example , when you say one in Mathematics language, what is this one you mean or intend? That is what is one? Is it a specific man or an animal or something abstract or any creature of the creatures of the natural world? The one we are talking about is neither this nor that and you can use it to talk about one human being or one animal or one creature. Therefore, the concept of the one is something abstract and it is so far from the creatures of the exterior world. Geometry has the same case. Triangle, quarter and rectangle as such are mere geometrical shapes and are far away from real life language. But when we use them in our daily life language we give them specific life meanings. -/- As I said, Aristotle was impressed by the language of Mathematics and wanted to build a similar language for logic .The rationale behind this is to get away from the language of ambiguity caused by the use of daily life language .One word or utterance in a language has many usages in one language or when translated into other languages , and therefore it causes many problems in usage instead of simplifying it and this is what Aristotle tried to avoid. Aristotle chose letters instead of words, the letter is part of the word, and the letter is meaningless unless it is a part of the word. The meaning of a letter depends on its occurrence in the word. If you compose a word from a group of letters and use it , it becomes ambiguous because it becomes part of the used language. -/- However, Aristotle did not combine letters in a word but he used them as abstract letters and gave them meanings in the language of logic where there is no divergence about its use. Aristotle used them in syllogism and they mean the limits of reason . Until recently critical thinking was part of formal logic and learning it means that you have logical background or at least you are familiar with the rules and fundamentals of logic. But critical thinking theorists soon took the initiative to separate it from logic because the latter started to suffer from its rules which are difficult to understand and which require some awareness and thoughts on the part of the scholar to understand. Hence , critical thinking is not supposed to possess a background of logic and it adopts a specific questioning approach where it suggests a number of questions the practitioner of critical thinking has to successively answer since he has to make sure that the opinion he reaches does not rely on any subjective considerations. This is how the skills that are acquired on a continuum of related critical questions are established ,this is not to mention that the concept of critical thinking itself is usually defined in this context as the awareness of such kinds of questions and the ability to arouse and answer them at appropriate times. My paper explains, How to be able to implement these skills in high education and what are the benefits of these skills? The paper includes; Critical Thinking and Logic Socrates `s Approach The impact of critical thinking on teaching methods Questioning How questions are organized in the light of critical thinking?

Frans de Waal (1948-2024) transformed our understanding of primate cognition and social behavior, shaping the perspectives of scientists, philosophers, and the general public through his groundbreaking research and engaging popular books.

This paper addresses several questions related to the nature, production, and use of animal-human (a-h) chimeras. At the heart of the issue is whether certain types of a-h chimeras should be brought into existence, and, if they are, how we should treat such creatures. In our current research environment, we recognize a dichotomy between research involving nonhuman animal subjects and research involving human subjects, and the classification of a research protocol into one of these categories will trigger different (...) ethical standards as to the moral permissibility of the research in question. Are a-h chimeras entitled to the more restrictive and protective ethical standards applied to human research subjects? We elucidate an Aristotelian-Thomistic metaphysical framework in which to argue how such chimeras ought to be defined ontologically. We then examine when the creation of, and experimentation upon, certain types of a-h chimeras may be morally permissible. (shrink)

In the long history of moral theory, non-human animals—hereafter, just animals—have often been neglected entirely or have been relegated to some secondary status. Since its emergence in the early 19th century, utilitarianism has made a difference in that respect by focusing upon happiness or well-being (and their contraries) rather than upon the beings who suffer or enjoy. Inevitably, that has meant that human relations to and use of other animals have appeared in a different light. Some cases have seemed easy: (...) once admit that the interests of animals matter and there can be little hesitation in condemning their cruel treatment. Among the more difficult cases has been the bearing of utilitarianism upon the use of animals in various kinds of research where, though the animals might suffer, there were believed to be prospects of great human benefit and where no cruel or malicious motives need be involved. What I shall provide in the current paper is an extended discussion of the bearing of utilitarianism upon practices of animal research. Since such practices have attracted both utilitarian criticism and defense, this will require the examination of arguments on both sides, including consideration of the human benefits, the animal costs, and the ways in which the one can be weighed against the other.

This article provides the foundation for a new predictive theory of animal learning that is based upon a simple logical model. The knowledge of experimental subjects at a given time is described using logical equations. These logical equations are then used to predict a subject’s response when presented with a known or a previously unknown situation. This new theory suc- cessfully anticipates phenomena that existing theories predict, as well as phenomena that they cannot. It provides a theoretical account for (...) phenomena that are beyond the domain of existing models, such as extinction and the detection of novelty, from which “external inhibition” can be explained. Examples of the methods applied to make predictions are given using previously published results. The present theory proposes a new way to envision the minimal functions of the nervous system, and provides possible new insights into the way that brains ultimately create and use knowledge about the world.

This paper argues for two claims. (1) In his biological views, Kenelm Digby tries to reconcile aspects of an Aristotelian theory of composite substance with early modern corpuscularianism. (2) From a methodological point of view, he uses the Stoic-Epicurean epistemology of common notions in order to show the adequacy of his conciliatory approach. The first claim is substantiated by an analysis of Digby’s views on the role of mixture and homogeneity in the process of animal generation. The second claim (...) is substantiated by an analysis of Digby’s views on the role of the concept of quantity in the evaluation of scientific hypotheses. Both arguments make use of the context of Digby’s philosophy: the first argument draws on his background in the work of early modern corpuscularian Aristotelians such as Daniel Sennert; the second argument draws on his background in the epistemology of Pierre Gassendi.

Lilly was one of the greatest scientists and pioneers on the limits of human possibility but after his death a collective amnesia has descended and he is now almost forgotten. His Wiki is good but inevitably incomplete so here are a few missing details and viewpoints. Lilly was a generation (or more) ahead of his time. He is almost single-handedly responsible for the great interest in dolphins (which led to the Marine Mammal Protection Act in the USA and helped to (...) found the animal rights movement). In 1958 he noted that the brains of elephants and cetaceans were larger than ours, that we should not abuse them and that it was one our most important projects to communicate with them. He invented sensory isolation tanks (at NIMH in 1954) and used them extensively with and without powerful psychoactive drugs at a time when it was thought that either the brain would shut down or one would go insane if external stimuli were eliminated. He created methods for implanting electrodes in mammal brains and was planning to do it to himself. He was one of the first to make serious use of computers in bioscience research and created the hardware and software to make the first attempts to communicate with dolphins. He self experimented with dangerous physiological investigations in high altitude medicine for the military during WW2, took LSD with dolphins and movie stars, submitted himself to the rigors of various forms of yoga and of Arica training, and taught classes at Esalen. He was a computer pioneer who forsaw the rapid advances in A.I. and it's inevitable clash with humans. He was the first one to investigate the bizarre psychedelic ketamine (" vitamin K "), and his results (published in the two last chapters of his book `The Scientist`) are still the best data on the dose/effect relation of any psychedelic on one person. It cured his lifelong daily migraine headaches (see http://www.conspiracyarchive.com/UFOs/Gorightly.htm). And all this happened before most of us were born! He had courage, honesty and integrity that is rare anywhere and almost nonexistent in science. His goal was to find the ultimate truth about everything and he went about as far as anyone ever has. He had little patience with the stupid and hypocritical games one has to play to fit into monkey society. Of course the reaction of the establishment was predictable. He left the NIMH and was never given any government or academic support for the last 35 years of his life. His paper and comments at a conference on sensory deprivation were removed from the published version. He was not invited to government sponsored symposia on dolphins (he had refused to help develop them as weapons), though he clearly knew more about them than anyone in the world. He liked to live and work on the edge and few could keep up with him, as his books make clear. If you have read some of his other books it will be much easier going. He was a pioneer in consciousness research and pushed the boundaries of our understanding of who we are and what we might become. Among other things he catalogs the various states reached by drugs, meditation, and isolation, tries to determine their significance, and suggests how to use them.

Beyond the Brain: How Body and Environment Shape Animal and Human Minds is an eye-opening and thought- provoking book that sets out a much-needed contribution to the study of the relationship between animals, cognition and the environment. The volume provides remarkable new insights into how to understand animal (including human) behavior, raises interesting questions about the role of environmental affordances in the emergence of complex cognitive processes and provides the reader with a refreshing break from the wearisome excess (...) of brain-centric literature that still pervades much of the debate surrounding evolutionary psychology. In embracing the theoretical framework endorsed by proponents of embodied cognition, Barrett adopts an ecological approach to psychology that aims at challenging any attempt to describe complex thinking and flexible behavior as mere by-products of internal cognitive activity.

This book attempts to advance Donald Griffin's vision of the "final, crowning chapter of the Darwinian revolution" by developing a philosophy for the science of animal consciousness. It advocates a Darwinian bottom-up approach that treats consciousness as a complex, evolved, and multidimensional phenomenon in nature rather than a mysterious all-or-nothing property immune to the tools of science and restricted to a single species. -/- The so-called emergence of a science of consciousness in the 1990s has at best been a (...) science of human consciousness. This book aims to advance a true Darwinian science of consciousness in which its evolutionary origin, function, and phylogenetic diversity are moved from the field’s periphery to its very centre, thus enabling us to integrate consciousness into an evolutionary view of life. Accordingly, this book has two objectives: (i) to argue for the need and possibility of an evolutionary bottom-up approach that addresses the problem of consciousness in terms of the evolutionary origins of a new ecological lifestyle that made consciousness worth having and (ii) to articulate a thesis and beginnings of a theory of the place of consciousness as a complex evolved phenomenon in nature that can help us to answer the question of what it is like to be a bat, an octopus, or a crow. -/- A Philosophy for the Science of Animal Consciousness will appeal to researchers and advanced students interested in advancing our understanding of animal minds as well as anyone with a keen interest in how we can develop a science of animal consciousness.

‘Sentience’ sometimes refers to the capacity for any type of subjective experience, and sometimes to the capacity to have subjective experiences with a positive or negative valence, such as pain or pleasure. We review recent controversies regarding sentience in fish and invertebrates and consider the deep methodological challenge posed by these cases. We then present two ways of responding to the challenge. In a policy-making context, precautionary thinking can help us treat animals appropriately despite continuing uncertainty about their sentience. In (...) a scientific context, we can draw inspiration from the science of human consciousness to disentangle conscious and unconscious perception (especially vision) in animals. Developing better ways to disentangle conscious and unconscious affect is a key priority for future research. (shrink)

One of the primary concerns in animal research is ensuring the welfare of laboratory animals. Modern views on animal welfare emphasize the role of animal sentience, i.e. the capacity to experience subjective states such as pleasure or suffering, as a central component of welfare. The increasing official recognition of animal sentience has had large effects on laboratory animal research. The Cambridge Declaration on Consciousness (Low et al., University of Cambridge, 2012) marked an official scientific recognition (...) of the presence of sentience in mammals, birds, and cephalopods. Animal sentience has furthermore been recognized in legislation in the European Union, UK, New Zealand and parts of Australia, with discussions underway in other parts of the world to follow suit. In this paper, we analyze this shift towards recognition of sentience in the regulation and practice in the treatment of laboratory animals and its effects on animal welfare and use. (shrink)

Animal welfare has a long history of disregard. While in recent decades the study of animal welfare has become a scientific discipline of its own, the difficulty of measuring animal welfare can still be vastly underestimated. There are three primary theories, or perspectives, on animal welfare - biological functioning, natural living and affective state. These come with their own diverse methods of measurement, each providing a limited perspective on an aspect of welfare. This paper describes a (...) perspectival pluralist account of animal welfare, in which all three theoretical perspectives and their multiple measures are necessary to understand this complex phenomenon and provide a full picture of animal welfare. This in turn will offer us a better understanding of perspectivism and pluralism itself. (shrink)

How does consciousness vary across the animal kingdom? Are some animals ‘more conscious’ than others? This article presents a multidimensional framework for understanding interspecies variation in states of consciousness. The framework distinguishes five key dimensions of variation: perceptual richness, evaluative richness, integration at a time, integration across time, and self-consciousness. For each dimension, existing experiments that bear on it are reviewed and future experiments are suggested. By assessing a given species against each dimension, we can construct a consciousness profile (...) for that species. On this framework, there is no single scale along which species can be ranked as more or less conscious. Rather, each species has its own distinctive consciousness profile. (shrink)

What is it like to be a bat? What is it like to be sick? These two questions are much closer to one another than has hitherto been acknowledged. Indeed, both raise a number of related, albeit very complex, philosophical problems. In recent years, the phenomenology of health and disease has become a major topic in bioethics and the philosophy of medicine, owing much to the work of Havi Carel (2007, 2011, 2018). Surprisingly little attention, however, has been given to (...) the phenomenology of animal health and suffering. This omission shall be remedied here, laying the groundwork for the phenomenological evaluation of animal health and suffering. (shrink)

In debates about animal sentience, the precautionary principle is often invoked. The idea is that when the evidence of sentience is inconclusive, we should “give the animal the benefit of the doubt” or “err on the side of caution” in formulating animal protection legislation. Yet there remains confusion as to whether it is appropriate to apply the precautionary principle in this context, and, if so, what “applying the precautionary principle” means in practice regarding the burden of proof (...) for animal sentience. Here I construct a version of the precautionary principle tailored to the question of animal sentience together with a practical framework for implementing it. I explain and defend the key features of this framework, argue that it is well-aligned with current practice in animal welfare science, and consider and reject a number of influential counterarguments to the use of precautionary reasoning in this area.

Animal welfare is a concept that plays a role within both our moral deliberations and the relevant areas of science. The study of animal welfare has impacts on decisions made by legislators, producers and consumers with regards to housing and treatment of animals. Our ethical deliberations in these domains need to consider our impact on animals, and the study of animal welfare provides the information that allows us to make informed decisions. This thesis focusses on taking a (...) philosophical perspective to answer the question of how we can measure the welfare of animals. Animal welfare science is an applied area of biology, aimed at measuring animal welfare. Although philosophy of animal ethics is common, philosophy focussing on animal welfare science is rare. Despite this lack, there are definitely many ways in which philosophical methods can be used to analyse the methodologies and concepts used in this science. One of the aims of the work in this thesis is to remedy this lack of attention in animal welfare. Animal welfare science is a strong emerging discipline, but there is the need for conceptual and methodological clarity and sophistication in this science if it is to play the relevant informative role for our practical and ethical decision-making. There is thus is a strong role here for philosophical analysis for this purpose. The central aim of this thesis is to provide an account of how we can measure subjective animal welfare, addressing some of the potential problems that may arise in this particular scientific endeavour. The two questions I will be answering are: what is animal welfare, and how do we measure it? Part One of the thesis looks at the subjective concept of animal welfare and its applications. In it, I argue for a subjective welfare view - that animal welfare should be understood as the subjective experience of individuals over their lifetimes - and look at how the subjective welfare concept informs our ethical decision-making in two different cases in applied animal ethics. Part Two of the thesis looks more closely at the scientific role of welfare. Understanding welfare subjectively creates unique measurement problems, due to the necessarily private nature of mental states and here I address a few of these problems, including whether subjective experience is measurable, how we might validate indicators of hidden target variables such as welfare, how we can make welfare comparisons between individual animals and how we might compare or integrate the different types of experience that make up welfare. I end with a discussion of the implications of all these problems and solutions for the practice of welfare science, and indicate useful future directions for research. (shrink)

Ethical vegans and vegetarians believe that it is seriously immoral to bring into existence animals whose lives would be miserable. In this paper, I will discuss whether such a belief also leads to the conclusion that it is seriously immoral to bring human beings into existence. I will argue that vegans should abstain from having children since they believe that unnecessary suffering should be avoided. After all, humans will suffer in life, and having children is not necessary for a good (...) life. Thus vegans, and probably vegetarians as well, should not have children. I will consider several objections against this controversial claim, show why the objections fail and conclude that it would be best for ethical vegans to abstain from procreation. (shrink)

We welcome Mikhalevich & Powell’s (2020) (M&P) call for a more “‘inclusive”’ animal ethics, but we think their proposed shift toward a moral framework that privileges false positives over false negatives will require radically revising the paradigm assumption in animal research: that there is a clear line to be drawn between sentient beings that are part of our moral community and nonsentient beings that are not.

While we agree in broad strokes with the characterisation of rationalization as a “useful fiction,” we think that Fiery Cushman's claim remains ambiguous in two crucial respects: (1) the reality of beliefs and desires, that is, the fictional status of folk-psychological entities and (2) the degree to which they should be understood as useful. Our aim is to clarify both points and explicate the rationale of rationalization.

Though many ethicists have the intuition that we should leave nature alone, Kyle Johannsen argues that we have a duty to research safe ways of providing large-scale assistance to wild animals. Using concepts from moral and political philosophy to analyze the issue of wild animal suffering (WAS), Johannsen explores how a collective, institutional obligation to assist wild animals should be understood. He claims that with enough research, genetic editing may one day give us the power to safely intervene without (...) perpetually interfering with wild animals’ liberties.---------------Questions addressed include: In what way is nature valuable and is interference compatible with that value? Is interference a requirement of justice? What are the implications of WAS for animal rights advocacy? What types of intervention are promising?---------------Expertly moving the debate about human relations with wild animals beyond its traditional confines, Wild Animal Ethics is essential reading for students and scholars of political philosophy and political theory studying animal ethics, environmental ethics, and environmental philosophy.

While growing empirical evidence suggests a continuity between human and non-human psychology, many philosophers still think that only humans can act and form beliefs rationally. In this paper, we challenge this claim. We first clarify the notion of rationality. We then focus on the rationality of beliefs and argue that, in the relevant sense, humans are not the only rational animals. We do so by first distinguishing between unreflective and reflective responsiveness to epistemic reasons in belief formation and revision. We (...) argue that unreflective responsiveness is clearly within the reach of many animals. We then defend that a key demonstration of reflective responsiveness would be the ability to respond to undermining defeaters. We end by presenting some empirical evidence that suggests that some animal species are capable of processing these defeaters, which would entail that even by the strictest standards, humans are not the only rational animals.

Over the course of the twentieth century, the notion of the systematicity of thought has acquired a much narrower meaning than it used to carry for much of its history. The so-called “systematicity debate” that has dominated the philosophy of language, cognitive science, and AI research over the last thirty years understands the systematicity of thought in terms of the compositionality of thought. But there is an older, broader, and more demanding notion of systematicity that is now increasingly relevant again. (...) To recover this notion from under the shadow of the systematicity debate, I distinguish between (i) the systematicity of thinkable contents, (ii) the systematicity of thinking, and (iii) the ideal of systematic thought. I then deploy this distinction to critically evaluate Fodor’s systematicity-based argument for the language of thought hypothesis before recovering the notion of the systematicity of thought as a regulative ideal, which has historically shaped our understanding of what it means for thought to be rational, authoritative, and scientific. To assess how much systematicity we need from AI models, I argue that we must look to the rationales for systematizing thought. To this end, I recover five such rationales from the history of philosophy and identify five functions served by systematization. Finally, I show how these can be used to arrive at a dynamic understanding of the need to systematize thought that can tell us what kind of systematicity is called for and when. (shrink)

Observations of animals engaging in apparently moral behavior have led academics and the public alike to ask whether morality is shared between humans and other animals. Some philosophers explicitly argue that morality is unique to humans, because moral agency requires capacities that are only demonstrated in our species. Other philosophers argue that some animals can participate in morality because they possess these capacities in a rudimentary form. Scientists have also joined the discussion, and their views are just as varied as (...) the philosophers’. Some research programs examine whether animals countenance specific human norms, such as fairness. Other research programs investigate the cognitive and affective capacities thought to be necessary for morality. There are two sets of concerns that can be raised by these debates. They sometimes suffer from there being no agreed upon theory of morality and no clear account of whether there is a demarcation between moral and social behavior; that is, they lack a proper philosophical foundation. They also sometimes suffer from there being disagreement about the psychological capacities evident in animals. Of these two sets of concerns—the nature of the moral and the scope of psychological capacities—we aim to take on only the second. In this chapter we defend the claim that animals have three sets of capacities that, on some views, are taken as necessary and foundational for moral judgment and action. These are capacities of care, capacities of autonomy, and normative capacities. Care, we argue, is widely found among social animals. Autonomy and normativity are more recent topics of empirical investigation, so while there is less evidence of these capacities at this point in our developing scientific knowledge, the current data is strongly suggestive.

Following recent arguments that cultural practices in wild animal populations have important conservation implications, we argue that recognizing captive animals as cultural has important welfare implications. Having a culture is of deep importance for cultural animals, wherever they live. Without understanding the cultural capacities of captive animals, we will be left with a deeply impoverished view of what they need to flourish. Best practices for welfare should therefore require concern for animals’ cultural needs, but the relationship between culture and (...) welfare is also extremely complex, requiring us to rethink standard assumptions about what constitutes and contributes to welfare.

De-extinction is the process through which extinct species can be brought back into existence. Although these projects have the potential to cause great harm to animal welfare, discussion on issues surrounding de-extinction have focussed primarily on other issues. In this paper, I examine the potential types of welfare harm that can arise through de-extinction programs, including problems with cloning, captive rearing and re-introduction. I argue that welfare harm should be an important consideration when making decisions on de-extinction projects. Though (...) most of the proposed benefits of these projects are insufficient to outweigh the current potential welfare harm, these problems may be overcome with further development of the technology and careful selection of appropriate species as de-extinction candidates.

The practice of ‘management euthanasia’, in which zoos kill otherwise healthy surplus animals, is a controversial one. The debate over the permissibility of the practice tends to divide along two different views in animal ethics—animal rights and animal welfare. Traditionally, those arguments against the practice have come from the animal rights camp, who see it as a violation of the rights of the animal involved. Arguments in favour come from the animal welfare perspective, who (...) argue that as the animal does not suffer, there is no harm in the practice and it is justified by its potential benefits. Here, I argue that an expansion of the welfare view, encompassing longevity and opportunities for positive welfare, give stronger considerations against management euthanasia, which then require greater benefits to justify its use.

The study of animal cognition raises profound questions about the minds of animals and philosophy of mind itself. Aristotle argued that humans are the only animal to laugh, but in recent experiments rats have also been shown to laugh. In other experiments, dogs have been shown to respond appropriately to over two hundred words in human language. In this introduction to the philosophy of animal minds Kristin Andrews introduces and assesses the essential topics, problems and debates as (...) they cut across animal cognition and philosophy of mind. She addresses the following key topics: what is cognition, and what is it to have a mind? What questions should we ask to determine whether behaviour has a cognitive basis? the science of animal minds explained: ethology, behaviourist psychology, and cognitive ethology rationality in animals animal consciousness: what does research into pain and the emotions reveal? What can empirical evidence about animal behaviour tell us about philosophical theories of consciousness? does animal cognition involve belief and concepts; do animals have a ‘Language of Thought’? animal communication other minds: do animals attribute ‘mindedness’ to other creatures? moral reasoning and ethical behaviour in animals animal cognition and memory. Extensive use of empirical examples and case studies is made throughout the book. These include Cheney and Seyfarth’s ververt monkey research, Thorndike’s cat puzzle boxes, Jensen’s research into humans and chimpanzees and the ultimatum game, Pankseep and Burgdorf’s research on rat laughter, and Clayton and Emery’s research on memory in scrub-jays. Additional features such as chapter summaries, annotated further reading and a glossary make this an indispensable introduction to those teaching philosophy of mind, animal cognition. It will also be an excellent resource for those in fields such as ethology, biology and psychology. (shrink)

Which animals have conscious experiences? Many different, diverse and unrelated behaviors and cognitive capacities have been proposed as tests of the presence of consciousness in an animal. It is unclear which of these tests, if any, are valid. To remedy this problem, I develop a list consisting of eight desiderata which can be used to assess putative tests of animal consciousness. These desiderata are based either on detailed analogies between consciousness-linked human behavior and non-human behavior, on theories of (...) consciousness or on methods from human consciousness science. If a test or set of tests satisfies more of these desiderata, passing it provides stronger evidence of consciousness. Moreover, one can design future tests of animal consciousness with the intention of satisfying these desiderata to ensure their evidential strength. (shrink)

Peter Carruthers has recently argued for a surprising conditional: if a global workspace theory of phenomenal consciousness is both correct and fully reductive, then there are no substantive facts to discover about phenomenal consciousness in nonhuman animals. I present two problems for this conditional. First, it rests on an odd double-standard about the ordinary concept of phenomenal consciousness: its intuitive non-gradability is taken to be unchallengeable by future scientific developments, whereas its intuitive determinacy is predicted to fall by the wayside. (...) Second, it relies on dismissing, prematurely, the live empirical possibility that phenomenal consciousness may be linked to a core global broadcast mechanism that is shared by a wide range of animals. Future developments in the science of consciousness may lead us to reconsider the non-gradability of phenomenal consciousness, but they are unlikely to lead us to accept that there are no facts to discover outside the paradigm case of a healthy adult human.
