There is a growing body of writing, for instance from the nursing profession, espousing an approach to ethics based on care. I suggest that this approach is hopelessly vague and that the vagueness is due to an inadequate analysis of the concept of care. An analysis of 'care' and related terms suggests that care is morally neutral. Caring is not good in itself, but only when it is for the right things and expressed in the right way. 'Caring' ethics assumes (...) wrongly that caring is good, thus it can tell us neither what constitutes those right things, nor what constitutes the right way. (shrink)

We formalize what it means to have permission to say something. We adapt the dynamic logic of permission by van der Meyden (J Log Comput 6(3):465–479, 1996 ) to the case where atomic actions are public truthful announcements. We also add a notion of obligation. Our logic is an extension of the logic of public announcements introduced by Plaza ( 1989 ) with dynamic modal operators for permission and for obligation. We axiomatize the logic and show that it is decidable.

We locate winning strategies for various ${\mathrm{\Sigma }}_{3}^{0}$ -games in the L-hierarchy in order to prove the following: Theorem 1. KP+Σ₂-Comprehension $\vdash \exists \alpha L_{\alpha}\ models"\Sigma _{2}-{\bf KP}+\Sigma _{3}^{0}-\text{Determinacy}."$ Alternatively: ${\mathrm{\Pi }}_{3}^{1}\text{\hspace{0.17em}}-{\mathrm{C}\mathrm{A}}_{0}\phantom{\rule{0ex}{0ex}}$ "there is a β-model of ${\mathrm{\Delta }}_{3}^{1}-{\mathrm{C}\mathrm{A}}_{0}\text{\hspace{0.17em}}\text{\hspace{0.17em}}+\text{\hspace{0.17 em}}{\mathrm{\Sigma }}_{3}^{0}$ -Determinacy." The implication is not reversible. (The antecedent here may be replaced with ${\mathrm{\Pi }}_{3}^{1}\text{\hspace{0.17em}}\text{\hspace{0.17em}}\left({\mathrm{\Pi }}_{3}^{1}\right)-{\mathrm{C}\mathrm{A}}_{0}:\text{\hspace{0.17em}}{\mathrm{\Pi }}_{3}^{1}$ instances of Comprehension with only ${\mathrm{\Pi }}_{3}^{1}$ -lightface definable parameters—or even weaker theories.) Theorem 2. KP +Δ₂-Comprehension +Σ₂-Replacement + ${\mathrm{\Sigma }}_{3}^{0}\phantom{\rule{0ex}{0ex}}$ -Determinacy. (Here AQI (...) is the assertion that every arithmetical quasi-inductive definition converges.) Alternatively: $\Delta _{3}^{1}{\rm CA}_{0}+{\rm AQI}\nvdash \Sigma _{3}^{0}$ -Determinacy. Hence the theories: ${\mathrm{\Pi }}_{3}^{1}-{\mathrm{C}\mathrm{A}}_{0},\text{\hspace{0.17em}}{\mathrm{\Delta }}_{3}^{1}-{\mathrm{C}\mathrm{A}}_{0}+\text{\hspace{0.17em}}{\mathrm{\Sigma }}_{3}^{0}-\mathrm{D}\mathrm{e}\mathrm{t}\phantom{\rule{0ex}{0ex}}$ -Det, ${\mathrm{\Delta }}_{3}^{1}-{\mathrm{C}\mathrm{A}}_{0}+\mathrm{A}\mathrm{Q}\mathrm{I}$ , and ${\mathrm{\Delta }}_{3}^{1}-{\mathrm{C}\mathrm{A}}_{0}\phantom{\rule{0ex}{0ex}}$ are in strictly descending order of strength.

Anna Wexler and Laura Specker Sullivan (2023) draw on their positionality as Global North early career neuroethics scholars to initiate a meaningful and timely conversation on Translational Neuroet...

This essay presents a critique of current views of Hugo Grotius which erroneously see him as a major theorist of natural rights and a formative influence upon the rights theory of Thomas Hobbes. Especially singled out for criticism are the misconceptions due to Richard Tuck in a number of writings that discuss the political ideas of Grotius and Hobbes and the relationship between them. In an examination of Hobbes's conception of natural rights, the essay reaffirms its originality and notes its (...) revolutionary potential contrary to the main intention of Hobbes's own political doctrine.

Ideal interpretation is understanding a text in the best possible way. It is usually used when the text has a canonical status, such as the Bible or the U.S. Constitution. We argue that Zhu Xi’s view about interpreting the Four Books and Ronald Dworkin’s view about constitutional interpretation are examples of ideal interpretation and that their basic principles are similar. Each holds, roughly, that their target text contains moral truth; that the author’s mind requires the mediation of learning; that the (...) purpose of interpretation is not only to lead the reader to the moral truth but to become a better person; that all propositions are about the same moral truth or about political justice; that the interpretation ultimately must come from oneself, purged of prejudices; and that the only correct interpretation is one that captures the original meaning.

It is widely accepted that EinstcinRi7;s general theory of relativity is an satisfactory description of gravity 0nly in the macroscopic limit, where quantum eiTcc1;s may be neglected. Presumably this theory is inapplicable at the Planck length, but recently much attention has been devoted to gravitational theory at intermediate length scales where quantum affects 0f matter are inescapable, but where there is an general assumption that the gravitational Held may bc treated as a classical background, augmented if necessary by quamtizcd linearized (...) pertur-.

We consider notions of truth and logical validity defined in various recent constructions of Hartry Field. We try to explicate his notion of determinate truth by clarifying the path-dependent hierarchies of his determinateness operator.

An edition of the letters of Erasmus, regarded as one of the greatest humanist writers. All 12 volumes of this work have been reissued, complete with their scholarly apparatus of commentary and notes, as well as plates.

Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

This book brings together both new and previously published essays on the Greek political history of the fifth century BC and historiography. It examines the relationship between philosophy and social/political conditions, and includes a new analysis of Aristotle's views on slavery and a discussion of the practicality of Plato's political theories.

We present in this article a new logical system inspired from linear logic. This system is designed in order to express causality and dynamism. The cut elimination theorem holds for this logic. Examples of applications are given.

Open peer commentary on the article “Social Autopoiesis?” by Hugo Urrestarazu. Upshot: Hugo Urrestarazu’s social theoretical concept is reduced to the material reality. These suggestions exclude the essential constructivist character of the social and thereby important social phenomena by definition. The systems theoretical approach by Niklas Luhmann offers an adequate alternative.

In de eerste hoofdstukken van vakwetenschappelijke handboeken wordt de lezer vaak met de grenzen van de betreffende vakwetenschap geconfronteerd. Het terrein en de aard van de vakwetenschap worden geschetst en daarmee de plaats van het terrein binnen de werkelijkheid en de betekenis van de verworven kennis. Het is de filosofie eigen dat zij zich in tegenstelling tot de vakwetenschap langdurig ophoudt bij dergelijke grenzen en er regelmatig naar terugkeert. Voor de vakwetenschap betekent nadenken over de grenzen gedwongen oponthoud dat niet (...) tot gewenste resultaten leidt. Men gaat liever zo snel mogelijk het terrein op om daar onderzoek te doen. De filosofie blijft niet alleen langer stilstaan bij de grenzen, ze beweegt zich vervolgens ook in een andere richting dan de vakwetenschap, de richting van het meer omvattende. (shrink)
