Self-organized criticality (SOC) is based upon the idea that complex behavior can develop spontaneously in certain multi-body systems whose dynamics vary abruptly. This book is a clear and concise introduction to the field of self-organized criticality, and contains an overview of the main research results. The author begins with an examination of what is meant by SOC, and the systems in which it can occur. He then presents and analyzes computer models to describe a number of systems, and he explains (...) the different mathematical formalisms developed to understand SOC. The final chapter assesses the impact of this field of study, and highlights some key areas of new research. The author assumes no previous knowledge of the field, and the book contains several exercises. It will be ideal as a textbook for graduate students taking physics, engineering, or mathematical biology courses in nonlinear science or complexity. (shrink)

Ecosystems, the human brain, ant colonies, and economic networks are all complex systems displaying collective behaviour, or emergence, beyond the sum of their parts. Complexity science is the systematic investigation of these emergent phenomena, and stretches across disciplines, from physics and mathematics, to biological and social sciences. This introductory textbook provides detailed coverage of this rapidly growing field, accommodating readers from a variety of backgrounds, and with varying levels of mathematical skill. Part I presents the underlying principles of complexity science, (...) to ensure students have a solid understanding of the conceptual framework. The second part introduces the key mathematical tools central to complexity science, gradually developing the mathematical formalism, with more advanced material provided in boxes. A broad range of end of chapter problems and extended projects offer opportunities for homework assignments and student research projects, with solutions available to instructors online. Key terms are highlighted in bold and listed in a glossary for easy reference, while annotated reading lists offer the option for extended reading and research. (shrink)

ABSTRACT Nietzsche's texts invite perplexing questions about the justification and objectivity of his ethical views. According to the interpretation suggested here, Nietzsche does not advance a substantive normative ethics, but proposes, based on his ontological idea of will to power, an instrumentalist theory of value. He is not a realist about value—according to him, nothing is intrinsically valuable. However, things, actions, beliefs, and values can be evaluated with reference to their capacities in serving our fundamental quest for power. The central (...) advantage of this interpretation against competing readings is that it attempts to make sense of how an “objective” evaluation fits together with antirealism or nihilism about value, including how the “ethics” of will to power is to be understood alongside the metaphysical and ethical doctrine of eternal recurrence.

SUMMARYThis article discusses the works of the first two lecturers on natural law in Copenhagen, Henrik Weghorst and Christian Reitzer. Contrary to the existing scholarship which characterises their works as derivative of either Grotius or Pufendorf, the article argues that the character and significance of these works can only be grasped when understood in light of the local intellectual traditions which they built upon. Seen against this background, it becomes clear that Weghorst and Reitzer developed significantly different theories of (...) natural law, disagreeing on such fundamental issues as the definition of law, the moral good, and the role of sociality in natural law. Following a tradition of Christian natural law in Kiel, Weghorst developed a theory of natural law fundamentally critical of the secularising theories of Grotius and Pufendorf, while Reitzer followed Pufendorf and his disciple Christian Thomasius in Halle. The article concludes by indicating how Weghorst’s and Reitzer’s works established the framework for discussions of natural law in the first decades of the eighteenth century, suggesting the need for further research into the significance of natural law for the early enlightenment in Denmark–Norway.

K.E. Løgstrups disputats fra 1942 – nu i revideret udgave med Løgstrups senere tilføjelser og rettelser. Redaktion og efterskrift ved Kees van Kooten Niekerk. Den transcendentalfilosofiske Problemstillings Forstaaelse af Livet i sig selv som formløst og skikkelsesløst deler Teologien ikke. Den jødisk-kristne Livsforstaaelse er den modsatte: at Livet er noget bestemt, før og uanset den Skikkelse det vinder i Kulturen. Menneskelivet er ikke først og ikke udelukkende Kultur-Liv. I Israels Tro og i Jesu Forkyndelse er Livet i sig selv, uanset (...) hvilke Skikkelser Mennesket giver det i sin Kultur, noget bestemt, fordi det er skabt Liv.” "For Løgstrup-fortolkere er det spændende at følge Løgstrups udvikling, hvor de senere tanker om den etiske fordring som et humant begreb og de suveræne livsytringer tager sin begyndelse i disputatsen." **** Henrik Gade Jensen, Jyllands-Posten "Løgstrup starter sin videnskabelige karriere med at rydde grunden for det livtag med den sekulariserede, gudløse tilværelsesforståelse, der siden blev hans opgave tilværelsen igennem. Der er en enestående konsekvens i Løgstrups liv og tænkning fra først til sidst, en teologisk konsekvens. Det er det, der er det store ved ham." Niels Højlund, Weekendavisen. (shrink)

More than a decade of research has found strong evidence for P(if A, then C) = P(C|A) (“the Equation”). We argue, however, that this hypothesis provides an overly simplified picture due to its inability to account for relevance. We manipulated relevance in the evaluation of the probability and acceptability of indicative conditionals and found that relevance moderates the effect of P(C|A). This corroborates the Default and Penalty Hypothesis put forward in this paper. Finally, the probability and acceptability of concessive conditionals (...) (“Even if A, then still C”) were investigated and it was found that the Equation provides a better account of concessive conditionals than of indicatives across relevance manipulations. (shrink)

IN 1959 and 1960 I gave the Gifford Lectures in the University of St. Andrews. The lectures were called 'Norms and Values, an Inquiry into the Conceptual Foundations of Morals and Legislation'. The present work is substantially the same as the content of the second series of lectures, then advertised under the not very adequate title 'Values'. It is my plan to publish a revised version of the content of the first series of lectures, called 'Norms', as a separate book. (...) The two works will be independent of one another. (shrink)

In a recent article, William Simkulet has argued against the anti-abortion view by invoking the fact that many human fetuses die from spontaneous abortion. He argues that this fact poses a dilemma for proponents of the anti-abortion view: either they must abandon their anti-abortion view or they must engage in preventing spontaneous abortion significantly more than at present—either to the extent that they try to prevent induced abortion or at least significantly more than they do today. In this reply, I (...) acknowledge that, if the latter would follow, the anti-abortionist view would imply implausibly strong obligations. My aim with this reply is to demonstrate that anti-abortionists can hold on to their view without having implausibly strong obligations to prevent spontaneous abortion. My conclusion is that Simkulet clearly overstates his position by not sufficiently considering the differences between the act of killing versus death by natural causes and between positive and negative rights.

This paper argues that ‘the Anthropocene’ is a deeply depoliticizing notion. This de-politicization unfolds through the creation of a set of narratives, what we refer to as ‘AnthropoScenes’, which broadly share the effect of off-staging certain voices and forms of acting. Our notion of the Anthropo-obScene is our tactic to both attest to and undermine the depoliticizing stories of ‘the Anthropocene’. We first examine how various AnthropoScenes, while internally fractured and heterogeneous, ranging from geo-engineering and earth system science to more-than-human (...) and object-oriented ontologies, place things and beings, human and non-human, within a particular relational straitjacket that does not allow for a remainder or constitutive outside. This risks deepening an immunological biopolitical fantasy that promises adaptive and resilient terraforming, an earth system management of sorts that permits life as we know it to continue for some, while turning into a necropolitics for others. Second, we develop a post-foundational political perspective in relation to our dramatically changing socio-ecological situation. This perspective understands the political in terms of performance and, in an Arendtian manner, re-opens the political as forms of public-acting in common that subtracts from or exceeds what is gestured to hold socio-ecological constellations together. We conclude that what is off-staged and rendered obscene in ‘the AnthropoScenes’ carries precisely the possibility of a return of the political. (shrink)

In his article, The Substance View: a critique, Rob Lovering argues that the substance view – according to which the human embryo is a person entitled to human rights – leads to such implausible implications that this view should be abandoned. In this article I respond to his criticism by arguing that either his arguments fail because the proponents of the substance view are not obligated to hold positions which may be considered absurd, or because the positions which they are (...) assumed to be obligated to hold, are not absurd at all.

This paper examines precursors and consequents of perceived relevance of a proposition A for a proposition C. In Experiment 1, we test Spohn's assumption that ∆P = P − P is a good predictor of ratings of perceived relevance and reason relations, and we examine whether it is a better predictor than the difference measure − P). In Experiment 2, we examine the effects of relevance on probabilistic coherence in Cruz, Baratgin, Oaksford, and Over's uncertain “and-to-if” inferences. The results suggest (...) that ∆P predicts perceived relevance and reason relations better than the difference measure and that participants are either less probabilistically coherent in “and-to-if” inferences than initially assumed or that they do not follow P = P. Results are discussed in light of recent results suggesting that the Equation may not hold under conditions of irrelevance or negative relevance. (shrink)

According to the two-tragedies argument proponents of pro-life can justifiably prioritize efforts to prevent abortion rather than miscarriages due to the fact that abortions in contrast to miscarriages involves usually the act of killing. William Simkulet has recently argued against this argument claiming that it fails as it is in conflict with the common sense pro-life view on abortion and leads to an overestimation of the moral value of preventing the ‘second tragedy’, namely the act of killing, compared with the (...) value of preventing the death of an individual. In this article, I argue against to his charges against the two tragedies argument by demonstrating that this argument is not only compatible but also in line with the common sense pro-life view and that the argument does not overestimate moral significance of the act of killing.

Aggregating snippets from the semantic memories of many individuals may not yield a good map of an individual’s semantic memory. The authors analyze the structure of semantic networks that they sampled from individuals through a new snowball sampling paradigm during approximately 6 weeks of 1-hr daily sessions. The semantic networks of individuals have a small-world structure with short distances between words and high clustering. The distribution of links follows a power law truncated by an exponential cutoff, meaning that most words (...) are poorly connected and a minority of words has a high, although bounded, number of connections. Existing aggregate networks mirror the individual link distributions, and so they are not scale-free, as has been previously assumed; still, there are properties of individual structure that the aggregate networks do not reflect. A simulation of the new sampling process suggests that it can uncover the true structure of an individual’s semantic memory. (shrink)

Technologies can have profound effects on social moral systems. Is there any way to systematically investigate and anticipate these potential effects? This paper aims to contribute to this emerging field on inquiry through a case study method. It focuses on two core human values—truth and trust—describes their structural properties and conceptualisations, and then considers various mechanisms through which technology is changing and can change our perspective on those values. In brief, the paper argues that technology is transforming these values by (...) changing the costs/benefits of accessing them; allowing us to substitute those values for other, closely-related ones; increasing their perceived scarcity/abundance; and disrupting traditional value-gatekeepers. This has implications for how we study other, technologically-mediated, value changes. (shrink)

Ethics plays a key role in the normative analysis of the impacts of technology. We know that computers in general and the processing of data, the use of artificial intelligence, and the combination of computers and/or artificial intelligence with robotics are all associated with ethically relevant implications for individuals, groups, and society. In this article, we argue that while all technologies are ethically relevant, there is no need to create a separate ‘ethics of X’ or ‘X ethics’ for each and (...) every subtype of technology or technological property—e.g. computer ethics, AI ethics, data ethics, information ethics, robot ethics, and machine ethics. Specific technologies might have specific impacts, but we argue that they are often sufficiently covered and understood through already established higher-level domains of ethics. Furthermore, the proliferation of tech ethics is problematic because (a) the conceptual boundaries between the subfields are not well-defined, (b) it leads to a duplication of effort and constant reinventing the wheel, and (c) there is danger that participants overlook or ignore more fundamental ethical insights and truths. The key to avoiding such outcomes lies in a taking the discipline of ethics seriously, and we consequently begin with a brief description of what ethics is, before presenting the main forms of technology related ethics. Through this process, we develop a hierarchy of technology ethics, which can be used by developers and engineers, researchers, or regulators who seek an understanding of the ethical implications of technology. We close by deducing two principles for positioning ethical analysis which will, in combination with the hierarchy, promote the leveraging of existing knowledge and help us to avoid an exaggerated proliferation of tech ethics.

How can we assess the epistemic quality of democratic decision-making? Sceptics doubt such assessments are possible, as they must rely on controversial substantive standards of truth and rightness. Challenging that scepticism, this paper suggests a procedure-independent standard for assessing the epistemic quality of democratic decision-making by evaluating whether it is adequately supported by reasons. Adequate support for conclusion is a necessary aspect of epistemic quality for any epistemic justification of democracy, though particularly relevant to theories that emphasize public deliberation. Finding (...) existing methods for measuring the quality of public discourse to fall short, we draw on an epistemological theory of argumentation to provide a more sophisticated approach to evaluating the epistemic quality of democratic decision-making, illustrate how the approach can be used, and demonstrate its relevance for the epistemic turn in democratic theory.

While most theorists agree with the claim that human beings have high and equal moral standing, there are strong disagreements about how to justify this claim. These disagreements arise because there are different ways of managing the difficulty of finding a basis for this claim, which is sufficiently substantial to do this justifying work, but not vary in degree in order to not give rise to inequality of moral considerability. The aim of this paper is to review previous attempts to (...) address this difficulty and to demonstrate why they fail and then to defend another way of dealing with this challenge by applying two views: the substance view on the human person and the natural-law account of morality. My claim is that this approach has comparative advantages because it provides a binary and a normatively significant basis of justification for equality without being implausibly inclusive. (shrink)

In his article ‘The substance view: A critique’, Rob Lovering argues that the substance view –according to which a human person comes into existence at the moment of conception – leads to such implausible implications that this view should be abandoned. I responded to his reductio arguments in ‘A critique of Rob Lovering's criticism of the substance view’ and concluded that his arguments did not justify a rejection of the substance view. Now Lowering and William Simkulet have both responded to (...) my criticism, claiming that my criticism of Lovering's article did not refute his original arguments. In this article I respond to their criticism and conclude that, while the substance view has some less plausible implications, none of them justify a complete refutation of this view. (shrink)

How should one understand comparisons in which neither of two alternatives is at least as good as the other? Much recent literature on comparability problems focuses on what the appropriate explanation of the phenomenon is. Is it due to vagueness or the possibility of non-conventional comparative relations such as parity? This paper argues that the discussions on how to best explain comparability problems has reached an impasse at which it is hard to make any progress. To advance the discussion we (...) suggest a new classification of comparability problems that focuses on the problems they cause for practical reasoning. (shrink)

This article contains an overview of the author's long‐standing involvement with deontic logic, both from a technical and from a wider philosophical point of view. As far as the formal aspects of deontic logic are concerned, the author describes his intellectual development from the original discovery of the analogy between modal (and deontic) notions on the one hand, and quantifiers on the other, through the formulation of a systematic theory of dyadic deontic concepts, to the proposal of a formal logic (...) of action as a foundation for deontic logic. In a more philosophical vein, the author discusses such questions as the very possibility of deontic logic if norms have no truth‐value, the relation between the descriptive interpretation of classical deontic logic and the logic of norm‐propositions, the correct representation of conditional or hypothetical norms, the distinction between moral obligation and practical necessity, and the interdefinability of permission and obligation.

Abortion critics have argued that one should err on the side of life and prohibit abortion since the status of the fetus is uncertain. David Boonin has criticized this precautionary argument, but his criticism has been ignored. The aim is to elaborate on the precautionary argument by responding to Boonin’s criticism. Boonin considers three versions of the precautionary argument—the disaster avoidance argument, the maximin argument, and the expected utility argument; yet all three are judged unsuccessful for the same reasons: they (...) lead to unacceptable implications, they lead to conclusions that are too weak, and they undermine the integrity of moral reasoning. I respond to this criticism by arguing that one can avoid unacceptable implications by considering a criterion of realism, that the weaker conclusions are rather an advantage, and that the application of the precautionary principle makes room for considerations which maintain the integrity of moral reasoning. I also consider some criticism beyond Boonin’s objections. (shrink)

The two tragedies argument has been raised as a response to the argument against abortion from spontaneous abortion. According to this argument against the antiabortion position, miscarriages should be of great concern for proponents of this position since they result in a greater amount of deaths of human beings than induced abortions do. According to critics of AAP, this fact undermines its plausibility, since proponents of the AAP either must try to prevent miscarriages to the same extent as they try (...) to prevent abortions or abandon their opposition to at least some abortions—which are not acceptable options for proponents of APP. The claim of 2TA is that one can differentiate between induced abortion and miscarriages due to the fact that the former involves the act of killing of another human being. This fact adds a tragedy to the tragedy that both abortions and miscarriages result in – the death of a human being – and contributes to justifying the choice of proponents of AAP to prioritise the prevention of abortions rather than miscarriages. In this response, I defend 2TA against criticism that claims that this argument is: inconsistent with the AAP and trivialises the death of the fetus. My claim is that the first line of criticism rests on a misunderstanding of the premises of 2TA while the second line of criticism rests on a disanalogous thought experiment. I therefore conclude that these objections fail. (shrink)
