• Aggregates of previously isolated cells of Hydra are capable, under suitable solvant conditions, of regeneration forming complete animals. In a first stage, ecto- and endodermal cells sort out, producing the bilayered hollow structure characteristic of Hydra tissue; thereafter, heads are formed (even if the original cell preparation contained no head cells), eventually leading to the separation of normal animals with head, body column and foot. Hydra appears to be the highest type of organism that allows for regeneration of the (...) entire structure from random cell aggregates. The system is particularly useful for studying cell interactions, tissue polarity, pattern formation, and cell differentiation. (shrink)

Os minerais possuem uma influência direta em diversos processos fisiológicos no organismo animal e, mesmo com tamanha importância, por vezes são negligenciados pelos produtores para seu fornecimento para os animais. Este estudo teve como objetivo avaliar o desempenho reprodutivo de rebanhos de bovinos, caprinos e ovinos em 8 propriedades rurais nas cidades de Sanharó, Pesqueira, Arcoverde, Belo Jardim e São Bento do Una através da adição de suplemento mineral e mistura múltipla aos animais de forma a atender suas necessidades básicas (...) para mantença e reprodução. Foram avaliados os desempenhos de 4 touros e 25 vacas, 3 bodes e 50 cabras e 4 carneiros e 48 ovelhas em diferentes propriedades, avaliando como a adição de um suplemento mineral específico da espécie impacta de forma positiva nos índices reprodutivos avaliados que foram taxa de cio, taxa de serviço, taxa de concepção, taxa de fertilidade, taxa de prenhez, taxa de perdas gestacionais, taxa de natalidade e taxa de mortalidade. O experimento teve duração de 2 anos e pôde-se avaliar cerca de 2 partos nas vacas e, mais ou menos, 3 partos em cabras e ovelhas. Os dados foram computados e avaliados estatisticamente no Excel para conferir se os índices reprodutivos melhoraram em função da adição de minerais na ração dos animais. Conferiu-se que houve diferença significativa entre todos os índices avaliados, ou seja, a adição de minerais na ração dos animais melhora a eficiência reprodutiva de machos e fêmeas de animais ruminantes, sendo de suma importância sua disponibilização de forma correta para alcançar bons índices reprodutivos na fazenda na busca pela obtenção de neonatos que poderão ser comercializados. -/- REFERÊNCIAS BIBLIOGRÁFICAS ASTRO, G.

This article aims to read feminist new materialisms (Barad), together with ‘postulated’ linguistic or cultural primacy of Queer Theory (Butler), to show how both are engaged in similar critical-ethical endeavours. The central argument is that the criticism of Barad and new materialisms misses Butler’s materialistic insights due to a narrow interpretation of Butler's alleged social-constructivist position. There is, therefore, a specific focus on where they both make similar ethical appeals. Moreover, the article relies on Adorno's negative dialectic to highlight an (...) interpretation of Barad and Butler as being part of the same dialectical movement, in which materialism and idealism fluctuate in their mutual criticisms, thus continuing the procession towards 'new knowledge' and emancipation, or freedom, through their motions back and forth.

Both Philip and Andrew are philosophy students whose interests converge around the philosophy of technology broadly understood. Philip's interest is specifically aimed toward the ethics of Transhumanism and depictions of Transhumanism in works of fiction. On the other hand, Andrew finds himself more focused on religious behavior in the technological world. While the two perspectives might not seem that close, there is certain to be an overlap in Andrew and Philip's shared understanding of how technological phenomena play a crucial role (...) concerning religion and society.

ABSTRACT Offsetting is a very ineffective way to do good. Offsetting your lifetime emissions may increase aggregated life expectancy by at most seven years, while giving the amount it costs to offset your lifetime emissions to a malaria charity saves in expectation the life of at least one child. Is there any moral reason to offset rather than giving to some charity that does good so much more effectively? There might be such a reason if your offsetting compensated or somehow (...) benefitted the victims of your emission, since that could mean that you would satisfy the duty not to harm others by emitting and offsetting. But that is typically not true. If your emission harms some person and your offsetting benefits some person, then these are most likely different people. Hence, I conclude, we have a stronger reason to give to effective charities than we have to offset our emissions. (shrink)

The veil of ignorance argument was used by John C. Harsanyi to defend Utilitarianism and by John Rawls to defend the absolute priority of the worst off. In a recent paper, Lara Buchak revives the veil of ignorance argument, and uses it to defend an intermediate position between Harsanyi's and Rawls' that she calls Relative Prioritarianism. None of these authors explore the implications of allowing that agent's behind the veil are averse to ambiguity. Allowing for aversion to ambiguity---which is both (...) the most commonly observed and a seemingly reasonable attitude to ambiguity---however supports a version of Egalitarianism, whose logical form is quite different from the theories defended by the aforementioned authors. Moreover, it turns out that the veil of ignorance argument neither supports standard Utilitarianism nor Prioritarianism unless we assume that rational people are insensitive to ambiguity. (shrink)

I defend a weak version of the Pigou-Dalton principle for chances. The principle says that it is better to increase the survival chance of a person who is more likely to die rather than a person who is less likely to die, assuming that the two people do not differ in any other morally relevant respect. The principle justifies plausible moral judgements that standard ex post views, such as prioritarianism and rank-dependent egalitarianism, cannot accommodate. However, the principle can be justified (...) by the same reasoning that has recently been used to defend the core axiom of ex post prioritarianism and egalitarianism, namely, Pigou-Dalton for well-being. The arguably biggest challenge for proponents of Pigou-Dalton for chances is that it violates State Dominance for social prospects. However, I argue that we have independent reason for rejecting State Dominance for social prospects, since it prevents a social planner from properly respecting people's preferences. (shrink)

In this field questions arise which are certainly difficult; but as I listened last time to members of the group, I felt that the main difficulty perhaps lay in determining precisely what questions we are trying to answer. I have the conviction that if we could only say clearly what the questions are, the answers to them might not appear so elusive. So I have begun with a simple list of questions about discretion which in one form or another were, (...) as it seemed to me, expressed by the group last time. I may indeed have omitted something and inserted something useless: if so, no doubt I shall be informed of this later. The central questions then seem to me to be the following: 1. What is discretion, or what is the exercise of discretion? 2. Under what conditions and why do we in fact accept or tolerate discretion in a legal system? 3. Must we accept discretion or tolerate discretion, and if so, why? 4. What values does the use of discretion menace, and what values does it maintain or promote? 5. What can be done to maximize the beneficial operation of the use of discretion and to minimize any harm that it does? (shrink)

Many philosophers think that we should use a lottery to decide who gets a good to which two persons have an equal claim but which only one person can get. Some philosophers think that we should save identified persons from harm even at the expense of saving a somewhat greater number of statistical persons from the same harm. I defend a principled way of justifying both judgements, namely, by appealing to the decreasing marginal moral value of survival chances. I identify (...) four desiderata that, I contend, any such justification should satisfy, and explain how my account meets these desiderata, unlike some previous accounts. (shrink)

Neoclassical economists use expected utility theory to explain, predict, and prescribe choices under risk, that is, choices where the decision-maker knows---or at least deems suitable to act as if she knew---the relevant probabilities. Expected utility theory has been subject to both empirical and conceptual criticism. This chapter reviews expected utility theory and the main criticism it has faced. It ends with a brief discussion of subjective expected utility theory, which is the theory neoclassical economists use to explain, predict, and prescribe (...) choices under uncertainty, that is, choices where the decision-maker cannot act on the basis of objective probabilities but must instead consult her own subjective probabilities.

According to the orthodox treatment of risk preferences in decision theory, they are to be explained in terms of the agent's desires about concrete outcomes. The orthodoxy has been criticised both for conflating two types of attitudes and for committing agents to attitudes that do not seem rationally required. To avoid these problems, it has been suggested that an agent's attitudes to risk should be captured by a risk function that is independent of her utility and probability functions. The main (...) problem with that approach is that it suggests that attitudes to risk are wholly distinct from people's (non-instrumental) desires. To overcome this problem, we develop a framework where an agent's utility function is defined over chance propositions (i.e., propositions describing objective probability distributions) as well as ordinary (non-chance) ones, and argue that one should explain different risk attitudes in terms of different forms of the utility function over such propositions.

We present an epistemological schema of natural sciences inspired by Peirce's pragmaticist view, stressing the role of the \emph{phenomenological map}, that connects reality and our ideas about it. The schema has a recognisable mathematical/logical structure which allows to explore some of its consequences. We show that seemingly independent principles as the requirement of reproducibility of experiments and the Principle of Sufficient Reason are both implied by the schema, as well as Popper's concept of falsifiability. We show that the schema has (...) some power in demarcating science by first comparing with an alternative schema advanced during the first part of the 20th century which has its roots in Hertz and has been developed by Einstein and Popper. Further, the identified differences allow us to focus in the construction of Special Relativity, showing that it uses an intuited concept of velocity that does not satisfy the requirements of reality in Peirce. While the main mathematical observation connected with this issue has been known for more than a century, it has not been investigated from an epistemological point of view. A probable reason could be that the socially dominating epistemology in physics does not encourage such line of work. We briefly discuss the relation of the abduction process presented in this work with discussions regarding ``abduction'' in the literature and its relation with ``analogy''. (shrink)

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

The relationship between “Towards a Critique of Violence” (1921) and the work of Franz Kafka has been well established by several critical studies devoted to Walter Benjamin. However, it is striking that Benjamin himself, already well acquainted with the work of the Czech writer in 1921, never made any comment to Kafka’s work in this essay, and, more broadly, in any of the related texts that make up the project on the ‘Critique of Violence’. In this article, we analyze a (...) set of notions (Entstellung, Entsühnung, Zurechstellen) that allow us to establish a mediated relationship between this essay and the articles and letters that Benjamin devoted to Kafka in the 1930s. This relationship takes us back to the only piece in which Benjamin carries out an autonomous treatment of the “category of justice” (1916) in which he identifies -as it will happen eighteen years later, in the essay on Kafka (1934)- the locus of justice in the “non-violence”, thus untying the knot that binds in a perhaps indiscernible way in the Jewish tradition the notions of “messianism” and “violence”.

It has recently been argued that indeterminacy and indeterminism make most ordinary counterfactuals false. I argue that a plausible way to avoid such counterfactual skepticism is to postulate the existence of primitive modal facts that serve as truth-makers for counterfactual claims. Moreover, I defend a new theory of ‘might’ counterfactuals, and develop assertability and knowledge criteria to suit such unobservable ‘counterfacts’.

Laws can be evaluated as better or worse relative to different normative standards. But the standard set by the Rule of Law defines a kind-relative standard of evaluation: features like generality, publicity, and non-retroactivity make the law better as law. This fact about legal evaluation invites a comparison between law and other “goodness-fixing kinds,” where a kind is goodness-fixing if what it is to be a member of the kind fixes a standard for evaluating instances as better or worse. Indeed, (...) for any goodness-fixing kind, K, that sets a standard, S, for evaluating Ks as Ks, we can ask: (1) How does the nature of Ks explain S? (2) Does being a K depend on meeting a minimum threshold of S-relative goodness? In the case of law and its kind-relative standard defined by the Rule-of-Law virtues, these questions lack settled answers. Although Raz (1979, 2019) offers some discussion, I argue that his answers have the surprising upshot of rendering law sui generis relative to other goodness-fixing kinds, and that preserving continuity with other such kinds involves revising the general picture. On the revised picture, law construed as a system of rules is subject to kind-relative evaluation because it is (a) a functional artifact, (b) with an essential function of realizing a limited normative ideal, and (c) its being minimally good at that function—that is, its realization of the relevant normative ideal to some degree—is a condition and ground of law’s existence, since all functional artifacts appear to be subject to such threshold conditions.

Suppose that a decision-maker's aim, under certainty, is to maximise some continuous value, such as lifetime income or continuous social welfare. Can such a decision-maker rationally satisfy what has been called "continuity for easy cases" while at the same time satisfying what seems to be a widespread intuition against the full-blown continuity axiom of expected utility theory? In this note I argue that the answer is "no": given transitivity and a weak trade-off principle, continuity for easy cases violates the anti-continuity (...) intuition. I end the note by exploring an even weaker continuity condition that is consistent with the aforementioned intuition. (shrink)

Catastrophic risk raises questions that are not only of practical importance, but also of great philosophical interest, such as how to define catastrophe and what distinguishes catastrophic outcomes from non-catastrophic ones. Catastrophic risk also raises questions about how to rationally respond to such risks. How to rationally respond arguably partly depends on the severity of the uncertainty, for instance, whether quantitative probabilistic information is available, or whether only comparative likelihood information is available, or neither type of information. Finally, catastrophic risk (...) raises important ethical questions about what to do when catastrophe avoidance conflicts with equity promotion. (shrink)

A moderately risk averse person may turn down a 50/50 gamble that either results in her winning $200 or losing $100. Such behaviour seems rational if, for instance, the pain of losing $100 is felt more strongly than the joy of winning $200. The aim of this paper is to examine an influential argument that some have interpreted as showing that such moderate risk aversion is irrational. After presenting an axiomatic argument that I take to be the strongest case for (...) the claim that moderate risk aversion is irrational, I show that it essentially depends on an assumption that those who think that risk aversion can be rational should be skeptical of. Hence, I conclude that risk aversion need not be irrational. (shrink)

This essay rethinks the concept of biocommunism by rearticulating it via a sensitivity towards individual suffering rather than the human species as a whole. The essay is divided into three parts. The first part outlines Marx’s concept of alienation because of the central role that the fourth kind of alienation plays in Dyer-Witheford’s original conception of biocommunism. The second part briefly elaborates on the discussion of species in the Kyoto School. These two parts lead to the third part, where a (...) novel interpretation of biocommunism is outlined, focusing on individual suffering rather than the human species. (shrink)

Rowe has recently argued that pure risk of harm cannot itself be a harm. I respond to Rowe and argue that given an appropriate understanding of objective probabilities, pure objective risk of harm can itself be a harm.

This paper presents a new kind of problem in the ethics of distribution. The problem takes the form of several “calibration dilemmas,” in which intuitively reasonable aversion to small-stakes inequalities requires leading theories of distribution to recommend intuitively unreasonable aversion to large-stakes inequalities. We first lay out a series of such dilemmas for prioritarian theories. We then consider a widely endorsed family of egalitarian views and show that they are subject to even more forceful calibration dilemmas than prioritarian theories. Finally, (...) we show that our results challenge common utilitarian accounts of the badness of inequalities in resources. (shrink)

The Precautionary Principle (PP) is an influential principle of risk management. It has been widely introduced into environmental legislation, and it plays an important role in most international environmental agreements. Yet, there is little consensus on precisely how to understand and formulate the principle. In this paper I prove some impossibility results for two plausible formulations of the PP as a decision-rule. These results illustrate the difficulty in making the PP consistent with the acceptance of any trade-offs between catastrophic risks (...) and more ordinary goods. (shrink)

Advances in science and technology have added to our insights into the vulnerabilities of human agency as well as to the methods of exploiting them. This has raised the stakes for efforts to clarify the concept and ethics of manipulation. Among these efforts, Robert Noggle’s influencer-centered account of manipulation has been most significant. He defines manipulative acts as those whereby an agent intentionally influences a recipient’s attitudes so that they do not conform as closely as they otherwise would to the (...) pertinent norms and ideals endorsed by the influencer. This provides a relatively simple and in many ways clear definition of manipulation. It sidesteps thorny debates about autonomy, freedom, or practical rationality. It also promises to reveal a conceptual parallel between manipulating and lying, and thus to explain why manipulation is pro tanto wrong. In one respect, however, the account remains ambiguous: It remains unclear whether, and to what extent, it requires that influencers’ beliefs about what is ideal for their recipients to be grounded in some effort on the part of the influencer to identify with or take on the role of her recipient. This paper explains this ambiguity. It argues that influencer-centrism cannot remain indifferent to the validity of an agent’s beliefs about the ideal state of the recipient and provide an identification requirement that would render the whole account plausible and sufficiently determinate.

A social planner who evaluates risky public policies in light of the other risks with which their society will be faced should judge favourably some such policies even though they would deem them too risky when considered in isolation. I suggest that a longtermist would—or at least should—evaluate risky polices in light of their prediction about future risks; hence, longtermism supports social risk-taking. I consider two formal versions of this argument, discuss the conditions needed for the argument to be valid, (...) and briefly compare these conditions to some risky policy options with which actual public decision-makers are faced.

Immanuel Kant is a key thinker in the History of Western Philosophy whose ideas continue to fascinate contemporary English-speaking academic philosophers. One such idea is Kant's conception of transcendental arguments. Although these arguments do not originate in Kant's philosophy, Kant's conception of them occupies a special place in the English-speaking literature on the topic. A growing trend in this literature is to claim that Kant's transcendental arguments are unique because they aim to achieve an anti-skeptical end through deductive means. I (...) call the basic assumption behind readings of transcendental arguments like these the deductive/anti-skeptical assumption. This assumption claims that deduction is the best means to achieve an anti-skeptical end. In this thesis, I argue that accepting this assumption is one way to misinterpret transcendental arguments because—even though it seems compelling at first blush—it must be false. The resultant twist is that transcendental arguments cannot be deductive, which, in turn, means that understanding that Kant's transcendental arguments are not deductive in nature is itself no small detail for understanding the version of Kant's 'not-deductive' solution to skepticism developed here.

If I were asked to put forward an ethical principle which I considered to be especially certain, it would be that no one can be responsible, in the properly ethical sense, for the conduct of another. Responsibility belongs essentially to the individual. The implications of this principle are much more far-reaching than is evident at first, and reflection upon them may lead many to withdraw the assent which they might otherwise be very ready to accord to this view of responsibility. (...) But if the difficulties do appear to be insurmountable, and that, very certainly, does not seem to me to be the case, then the proper procedure will be, not to revert to the barbarous notion of collective or group responsibility, but to give up altogether the view that we are accountable in any distinctively moral sense.

Philosophers of science often make reference — whether tacitly or explicitly — to the notion of a scientific community. Sometimes, such references are useful to make our object of analysis tractable in the philosophy of science. For others, tracking or understanding particular features of the development of science proves to be tied to notions of a scientific community either as a target of theoretical or social intervention. We argue that the structure of contemporary scientific research poses two unappreciated, or at (...) least underappreciated, challenges to this concept of the “scientific community” in the philosophy of science. In particular, we will present two case studies from robotics research, broadly construed, which show that (1) the boundedness of the scientific community is threatened when private citizens can develop scientific and technological advances at minimal expense (democratization), and (2) the discreteness of scientific research programs is threatened by the complexly interrelated environment of contemporary scientific work (interconnectivity). Taken together, the extent of democratization and interconnectivity present a significant challenge for any practically oriented philosophy of science, one which we hope will be taken on directly by philosophers in the future.

In this paper, I will reread the history of molecular genetics from a psychoanalytical angle, analysing it as a case history. Building on the developmental theories of Freud and his followers, I will distinguish four stages, namely: (1) oedipal childhood, notably the epoch of model building (1943–1953); (2) the latency period, with a focus on the development of basic skills (1953–1989); (3) adolescence, exemplified by the Human Genome Project, with its fierce conflicts, great expectations and grandiose claims (1989–2003) and (4) (...) adulthood (2003–present) during which revolutionary research areas such as molecular biology and genomics have achieved a certain level of normalcy—have evolved into a normal science. I will indicate how a psychoanalytical assessment conducted in this manner may help us to interpret and address some of the key normative issues that have been raised with regard to molecular genetics over the years, such as ‘relevance’, ‘responsible innovation’ and ‘promise management’.

The Bayesian maxim for rational learning could be described as conservative change from one probabilistic belief or credence function to another in response to newinformation. Roughly: ‘Hold fixed any credences that are not directly affected by the learning experience.’ This is precisely articulated for the case when we learn that some proposition that we had previously entertained is indeed true (the rule of conditionalisation). But can this conservative-change maxim be extended to revising one’s credences in response to entertaining propositions or (...) concepts of which one was previously unaware? The economists Karni and Vierø (2013, 2015) make a proposal in this spirit. Philosophers have adopted effectively the same rule: revision in response to growing awareness should not affect the relative probabilities of propositions in one’s ‘old’ epistemic state. The rule is compelling, but only under the assumptions that its advocates introduce. It is not a general requirement of rationality, or so we argue. We provide informal counterexamples. And we show that, when awareness grows, the boundary between one’s ‘old’ and ‘new’ epistemic commitments is blurred. Accordingly, there is no general notion of conservative change in this setting.

This paper examines Santayana on imagination, and related themes, chiefly as these are expressed in his early work, Interpretations of Poetry and Religion (1900). My hypothesis is that Santayana under-estimates, in this book, the force and significance of the prevalent distinction between imagination and fancy, as this was originally put forward by Coleridge and later developed in Emerson’s late essays. I will focus on some of those aspects of Santayana’s book which appear to react to or to engage with Emerson’s (...) views and aim to bring Santayana’s treatment of the theme of imagination into relation with Emerson. Understanding the differences in greater detail we stand a better chance of reasoned evaluation of alternative conceptions of imagination. I will argue that the Coleridge-Emersonian conception of the distinction between imagination and fancy is a crucial element of the background of Peircean abduction, and in this fashion, contributes to the continuity of Emerson’s writings with the pragmatist tradition.

Ingenieur- und Naturwissenschaften sind Knoten eines engen Beziehungsgeflechts, in dem Mensch und Gesellschaft, Natur und Kultur weitere Knoten sind. Entwicklungen in diesen beiden Bereichen haben somit stets Auswirkungen sowohl auf die anderen Knoten als auf das Beziehungsgeflecht als Ganzes. Ingenieur- und Naturwissenschaften sind als ars humana zudem stets eine Form menschlicher Handlung. Damit werden sie zu einem Schlüsselproblem der theoretischen und praktischen Philosophie. Denn der Mensch, seine Handlungen und seine Eingliederung in die Gesellschaft stehen ebenso wie die Natur und die (...) Kultur seit jeher im Zentrum philosophischer Untersuchungen. Die Philosophie vermag diese beiden Wissenschaftsbereiche zu fundieren und kritisch zu begleiten. Philosophie, Ingenieur- und Naturwissenschaften haben das Vermögen, sich gegenseitig zu befruchten. In Anbetracht der humanen, sozialen und ökologischen Probleme des 21. Jhds. ist die fachbereichsübergreifende und partnerschaftliche Zusammenarbeit dieser drei Schlüsselbereiche unabdingbar. Sie ist eine nicht hintergehbare Grundbedingung aller Entwicklungen, die den Anspruch erheben, nachhaltig zu sein und damit dem normativen Leitziel folgen, heutigen und zukünftigen Generationen bedingungslos ein menschenwürdiges Leben zu ermöglichen. Ingenieure und Naturwissenschaftler können dabei einen wesentlichen Beitrag leisten. Die folgenden zehn Thesen begründen die Bedeutung einer an Nachhaltigkeit orientierten philosophischen Grundbildung von Ingenieuren und Naturwissenschaftlern. (shrink)

This book is a new scholarly edition of Lincoln Steffensâ classic, â oemuck-rakingâ account of Gilded Age corruption in America. It provides the broader political background, theoretical and historical context needed to better understand the social and political roots of corruption in general terms: the social and moral nature of corruption and reform. Steffens enjoyed the support of a multitude of journalists with first-hand knowledge of their localities. He interviewed and came to know political bosses, crusading district attorneys and indicted (...) corruptionists spanning a cast of hundreds. He also benefited from the support of a large-scale, nationally prominent network of anti-corruption specialists and luminaries, including President Theodore Roosevelt. Steffens explored in detail the high Gilded Age corruption of New York City, Chicago, â oecorrupt and contentedâ Philadelphia, Pittsburgh, St. Louis and Minneapolis. His work culminated in a well-documented record of Gilded Age corruption in the cities; and, with the addition of the editorial annotations, Chronology and Introduction of this edition, the reader is placed in a position to gain an overview and considerable insight into the general, moral and social-political phenomenon of corruption. This book will be of interest for students and professionals in political philosophy, political science, American history and American studies. (shrink)

This new critical edition is an examination of William James’s Essays in Radical Empiricism in light of the scientific naturalism prominent in James’s Principles of Psychology and the subsequent development of Darwinian, functional psychology and functionalism in psychology, the philosophy psychology and the philosophy of mind. This is sure to be a controversial look at James's late philosophy of "radical empiricism" and "pure experience." The critical perspective of the edition evokes realism of cognitive relations, contemporary empiricism and recent developments in (...) cognitive science and contemporary philosophy of mind.

This essay delves into the multifaceted concept of determin-ism within the domain of physics, scrutinizing prevalent definitions and classifications. Navigating through the nuances of deterministic behavior, we distinguish it from colloquial interpretations of "non-deterministic." By examining determin-ism through the lenses of natural laws, weak determinism, and strong determinism, we unravel the intricate relationship between predictability and the underlying mathematical structures of the universe. Classical mechanics serves as an exemplar of deterministic principles, while statistical mechanics introduces complexities that challenge simplistic classifications. (...) The interplay between ignorance and non-determinism emerges as a pivotal consideration, urging a nuanced understanding of deter-ministic frameworks amidst intricate systems. In essence, this exploration seeks to reconcile the richness of deterministic behavior with the complexities inherent in the natural world. (shrink)

Bartha and DesRoches (2021) and Steel and Bartha (2023) argue that we should understand the precautionary principle as the injunction to maximise lexical utilities. They show that the lexical utility model has important pragmatic advantages. Moreover, the model has the theoretical advantage of satisfying all axioms of expected utility theory except continuity. In this paper I raise a trilemma for any attempt at modelling the precautionary principle with lexical utilities: it permits choice cycles or leads to paralysis or implies that (...) the smallest value difference that is possible in a context has extreme axiological implications.
