A wide range of non-pharmaceutical interventions (NPIs) have been introduced to stop or slow down the COVID-19 pandemic. Examples include school closures, environmental cleaning and disinfection, mask mandates, restrictions on freedom of assembly and lockdowns. These NPIs depend on coercion for their effectiveness, either directly or indirectly. A widely held view is that coercive policies need to be publicly justified—justified to each citizen—to be legitimate. Standardly, this is thought to entail that there is a scientific consensus on the factual propositions (...) that are used to support the policies. In this paper, we argue that such a consensus has been lacking on the factual propositions justifying most NPIs. Consequently, they would on the standard view be illegitimate. This is regrettable since there are good reasons for granting the state the legitimate authority to enact NPIs under conditions of uncertainty. The upshot of our argument is that it is impossible to have both the standard interpretation of the permissibility of empirical claims in public justification and an effective pandemic response. We provide an alternative view that allows the state sufficient room for action while precluding the possibility of it acting without empirical support. (shrink)

Background Investigative genetic genealogy (IGG) is a technique that involves uploading genotypes developed from perpetrator DNA left at a crime scene, or DNA from unidentified remains, to public genetic genealogy databases to identify genetic relatives and, through the creation of a family tree, the individual who was the source of the DNA. As policymakers demonstrate interest in regulating IGG, it is important to understand public perspectives on IGG to determine whether proposed policies are aligned with public attitudes.Methods We conducted eight (...) focus groups with members of the public (N = 72), sampled from four geographically diverse US regions, to explore general attitudes and perspectives regarding aspects of IGG practices, applications, and policies. Five major topics were explored in each focus group: when IGG should be used; who should perform IGG; how to approach consent for genetic database users; what systems of oversight should govern IGG practitioners; and whether to notify database users if their data are involved in law enforcement (LE) matching.Results Participants were supportive of IGG in most scenarios, especially for cold and violent cases. The favorable attitudes toward IGG were, however, tempered by distrust of law enforcement among some participants. All participants agreed that databases must inform users if IGG is allowed, but they did not agree on how individual database users should be allowed to opt out or whether to notify them if their data are involved in specific investigations. All participants agreed that IGG should be subject to some prescriptive guidelines, regulations, or accountability mechanisms.Conclusions These findings suggest broad public support for IGG, and interest in developing systems of accountability for its practice. Our study provides useful insight for policy makers, genomic database stewards, law enforcement, and other stakeholders in IGG’s practice, and suggests multiple directions for future research.

In this essay I revisit The Prince and the Discourses and argue that across the design of these two texts on the theme of conspiracy Machiavelli constructs an ambush on Medici princes. I reconsider Mary Dietz's (1986), and Langton's and Dietz's (1987) suggestion that Machiavelli's The Prince was a deceptive political act through an exploration of the link Dietz and Sheldon Wolin (2004) draw between Machiavelli's method and Renaissance artistry. I suggest that Machiavelli applied a one-point linear perspective – a (...) scientific and visual method of pictorial representation and geometrical modelling that emerged for the first time in the Renaissance – to the political field. I test this hypothesis on the theme of conspiracy in Machiavelli’s work by arguing that The Prince ultimately presents one vantage point – that of the prince – while the Discourses offers another – that of the conspirators. I argue that a blind spot is created by these two texts when they are jointly considered: conspirators seduced, recruited, and trained by the Discourses eliminate a prince caught off guard for having followed the advice on conspiracy in The Prince.

Jean Buridan developed his theory of consequence within a semantical framework compatible with what we now call token-based semantics. In his Treatise on Consequences and Sophismata, Buridan showed...

El denominado “problema de los términos teóricos” que inicialmente formuló Sneed surge de la interpretación que de los términos teóricos hace la concepción heredada. Esta lectura no se condice con la interpretación indirecta de los términos teóricos que Carnap realiza al utilizar postulados. Estos textos proponen una interpretación holística de las teorías científicas, sólo adecuadamente tratada en una semántica de mundos posibles. Andreas proporciona un tratamiento modal de los términos teóricos; nosotros presentamos estos resultados en términos de modelos de Kripke; (...) luego los extendemos con el fin de que sean capaces de distinguir entre axiomas y oraciones teóricas, generando un modelo capaz de tratarlos de manera diferenciada y que aporte nuevos resultados lógicos y filosóficos.

Davidson’s account of singular causal statements as expressing relations between events together with his views on event identity lead to inferences involving causal statements which many of his critics find counterintuitive. These are sometimes said to be avoided on Kim’s view of events, in terms of which this line of criticism is often formulated. It is argued that neither Davidson nor Kim offer a satisfactory account of events - an essential prerequisit for the relational theory - and an account of (...) singular causal statements in terms of a modal sentential connective is advocated in place of the relational view. Such an account suffices to block the counter-intuitive inferences without needing to resort to a theory of events. It is suggested that a theory of events might be built upon a connective account of singular causal statements, but no such theory is presented here. (shrink)
