Many of the most serious crimes that fall within the justificatory scope of the harm principle do so constitutively. They do so in the sense that the harm that the crime is designed to prevent is a...

This paper explores the Offence Principle. It discusses whether two constraints, additional to the criteria stated in conventional analysis, ought to be met before the Offense Principle can be satisfied: (i) that offensive conduct must be a wrong, and (ii) that the conduct must also lead to harm. The nature of the Harm Principle, and its relationship to the Offense Principle, are also considered. The paper suggests that, even if all cases in which offense should be criminalized also involve harm, (...) nonetheless there may be good reasons to retain a separate Offense Principle. (shrink)

We discuss and respond to the contributions of Tatjana Hörnle, John Kleinig, and John Stanton-Ife, and clarify some aspects of the arguments made in Crimes, Harms, and Wrongs.

The text of the tract De arcubus similibus was published for the first time by M. Curtze in 1887. However, after examining some more Latin manuscripts and the Arabic MS Oxford, Bodleian Library, Marsh 663 it appeared, that Curtze's edition was rather an adaptation. Also Curtze's suggestion that Jordanus Nemorarius was the author was very probably wrong. The author of the tract was the Egyptian mathematician Ahmed ibn Jusuf as appears from the Latin manuscripts, and its translator, very probably, Gerard (...) of Cremona. In the tract Ahmed tried to prove, that the assertion ‘similar arcs are also equal arcs’ was wrong . His starting points were the propositions Euclid III, 20 and 21. Consequently, the tract can be looked upon as a commentary on the third book of the Elements. (shrink)

Moral behaviour, based on social norms, is commonly regarded as a hallmark of humans. Hitherto, humans are perceived to be the only species possessing social norms and to engage in moral behaviour. There is anecdotal evidence suggesting their presence in chimpanzees, but systematic studies are lacking. Here, we examine the evolution of human social norms and their underlying psychological mechanisms. For this, we distinguish between conventions, cultural social norms and universal social norms. We aim at exploring whether chimpanzees possess evolutionary (...) precursors of universal social norms seen in humans. Chimpanzees exhibit important preconditions for their presence and enforcement: tolerant societies, well-developed social-cognitive skills and empathetic competence. Here, we develop a theoretical framework for recognizing different functional levels of social norms and distinguish them from mere statistical behavioural regularities. Quasi social norms are found where animals behave functionally moral without having moral emotions. In proto social norms, moral emotions might be present but cannot be collectivized due to the absence of a uniquely human psychological trait, i.e. shared intentionality. Human social norms, whether they are universal or cultural, involve moral emotions and are collectivized. We will discuss behaviours in chimpanzees that represent potential evolutionary precursors of human universal social norms, with special focus on social interactions involving infants. We argue that chimpanzee infants occupy a special status within their communities and propose that tolerance towards them might represent a proto social norm. Finally, we discuss possible ways to test this theoretical framework. (shrink)

An alternative to the negative rights slant in animal rights, focusing on abolition and hands-off approaches, has now surfaced within critical animal studies. Indeed, Relational Animal Rights Theory lays a foundation for positive relations of care, mutuality and dependence between species. In so doing, the theory is sensitive to the multitude of ways in which human and non-human animals interact across shared territories. Perhaps the most fruitful development with RART is offered by Donaldson and Kymlicka, insofar as it extends a (...) positive relation also to wild animals. They present a tripartite framework for moral obligations toward non-human... (shrink)

Rewilding is positioned as ‘post’-conservation through its emphasis on unleashing the autonomy of natural processes. In this paper, we argue that the autonomy of nature rhetoric in rewilding is challenged by human interventions. Instead of joining critique toward the ‘managed wilderness’ approach of rewilding, however, we examine the injustices this entails for keystone species. Reintroduction case studies demonstrate how arbitrary standards for wildness are imposed on these animals as they do their assigned duty to rehabilitate ecosystems. These ‘Goldilocks’ standards are (...) predicated on aesthetic values that sanction interventions inconsistent with the premise of animal sovereignty. These include culling, relocations and sterilizations of animals that demonstrate the kind of autonomy championed in rewilding rhetoric. Drawing from Donaldson and Kymlicka’s framework for political animal categories, we conclude by arguing that rewilding needs to re-position itself in one of two ways. Either it should align itself more closely to mainstream conservation and embrace full animal sovereignty without Goldilocks conditions, or it should commit to taking full responsibility for reintroduced animals, including supplementary feeding and care.

People can support abstract reasoning by using mental models with spatial simulations. Such models are employed when people represent elements in terms of ordered dimensions (e.g. who is oldest, Tom, Dick, or Harry). We test and find that the process of forming and using such mental models can influence the liking of its elements (e.g. Tom, Dick, or Harry). The presumed internal structure of such models (linear-transitive array of elements), generates variations in processing ease (fluency) when using the model in (...) working memory (see the Symbolic Distance Effect, SDE). Specifically, processing of pairs where elements have larger distances along the order should be easier compared to pairs with smaller distances. Elements from easier pairs should be liked more than elements from difficult pairs (fluency being hedonically positive). Experiment 1 shows that unfamiliar ideographs are liked more when at wider distances and therefore easier to process. Experiment 2 replicates this effect with non-words. Experiment 3 rules out a non-spatial explanation of the effect while Experiments 4 offers a high-powered replication. Experiment 5 shows that the spatial effect spontaneously emerges after learning, even without a task that explicitly focuses on fluency. Experiment 6 employed a shorter array, but yielded no significant results. (shrink)

Knowing the individual skills and competences of one's group members may be important for deciding from whom to learn (social learning), with whom to collaborate and whom to follow. We investigated whether 12 jackdaws could select conspecifics based on their helping skills, which had been exhibited in a previous context. The birds were tested in a blocked-exit-situation, where they could choose between two conspecifics, one of which could be recruited inside. One conspecific had previously displayed the ability to open the (...) exit door whilst the other individual lacked the skill. The subjects showed a significant preference for the skilled conspecific if they had previously directly benefited from this skill. If they had merely observed the skilled (and non-skilled) individual opening (or failing to open) the exit door, they did not preferably choose the skilled conspecific. Taken together, these results suggest that jackdaws are capable of assessing other individuals' competence under certain circumstances. (shrink)
