Imperative sentences like Dance! do not seem to represent the world. Recent modal analyses challenge this idea, but its intuitive and historical appeal remain strong. This paper presents three new challenges for a non-representational analysis, showing that the obstacles facing it are even steeper than previously appreciated. I will argue that the only way for the non-representationalist to meet these three challenges is to adopt a dynamic semantics. Such a dynamic semantics is proposed here: imperatives introduce preferences between alternatives. This (...) characterization of meaning focuses on what function a sentence serves in discourse, rather than what that sentence refers to (e.g., a state of the world). By representing the meaning of imperatives, connectives and declaratives in a common dynamic format, the challenges posed for non-representationalism are met. (shrink)

A uniform theory of conditionals is one which compositionally captures the behavior of both indicative and subjunctive conditionals without positing ambiguities. This paper raises new problems for the closest thing to a uniform analysis in the literature (Stalnaker, Philosophia, 5, 269–286 (1975)) and develops a new theory which solves them. I also show that this new analysis provides an improved treatment of three phenomena (the import-export equivalence, reverse Sobel-sequences and disjunctive antecedents). While these results concern central issues in the study (...) of conditionals, broader themes in the philosophy of language and formal semantics are also engaged here. This new analysis exploits a dynamic conception of meaning where the meaning of a symbol is its potential to change an agent’s mental state (or the state of a conversation) rather than being the symbol’s content (e.g. the proposition it expresses). The analysis of conditionals is also built on the idea that the contrast between subjunctive and indicative conditionals parallels a contrast between revising and consistently extending some body of information.

In this paper, I examine various popular notions concerning the ethics of investing. I first consider and reject the absolutist view that it is always wrong to invest in evil companies and the view that what makes investments in evil companies morally objectionable is the fact that by making such investments, investors are taking steps to benefit from the wrongdoing of others. I then defend the view that what makes certain investments morally objectionable is the fact that by making such (...) investments, investors enable others to do wrong. According to this view, when weighing the purchase of a certain company's stock, investors should ask themselves the following question: Would this sort of investment, if made by many people, enable others to do wrong? If the answer to this question is yes, and if an investor nevertheless makes the investment in question, he can justifiably be accused of moral wrongdoing. (shrink)

The rapid pace of technological development often outstrips the ability of legislators and regulators to establish proper guardrails on emerging technologies. A solution is for those who develop, deploy, and use these technologies to develop themselves as moral agents—i.e., as agents capable of steering the course of emerging technologies in a direction that will benefit humanity. However, there is a dearth of literature discussing how to foster moral agency in computer science courses, and little if any research on the effectiveness (...) of such courses in computer science. This paper addresses this gap by providing an overview of an undergraduate course on technology ethics. It then shares and discusses a subset of data collected from a mixed-methods study using a pre-post design that sought to examine the course’s effectiveness in developing students’ moral, intellectual, and civic virtues, as well as related dispositions.

Abstract As there are food gluttons, so there are energy gluttons. One difference is that energy gluttons are typically oblivious to how much energy they consume and the source of that energy. Their energy gluttony is a side effect of insatiable desire for material goods, which themselves are often associated with social status. Nonetheless, steps taken to deal with energy gluttony parallel those taken with food gluttony. Typically these fall into three categories: educational, political, and technological. I will examine a (...) fourth, however, best characterized as philosophical. I will show how, by following the advice of the ancient Stoics and training ourselves to care less what others think of us, we can help overcome our desire for social status, resulting in a reduction in our desire for material things and a significant reduction in our personal energy bill. The pessimistic conclusion, however, is that most people are probably unwilling to undergo the self-analysis and self-transformation that this philosophical approach requires. (shrink)

This paper proposes a semantics for free choice permission that explains both the non-classical behavior of modals and disjunction in sentences used to grant permission, and their classical behavior under negation. It also explains why permissions can expire when new information comes in and why free choice arises even when modals scope under disjunction. On the proposed approach, deontic modals update preference orderings, and connectives operate on these updates rather than propositions. The success of this approach stems from its capacity (...) to capture the difference between expressing the preferences that give rise to permissions and conveying propositions about those preferences.

The history of Athenian relations with Sicily in the fifth century is beset with difficulties; and no part of it, perhaps, is more obscure than the story of what is commonly known as the First Sicilian Expedition, which set sail from Athens in the late summer of 427 under Laches, and was reinforced under Pythodorus, Sophocles and Eurymedon in the winter of 426.

This article updates the author’s 1982 argument that lutetium and lawrencium, rather than lanthanum and actinium, should be assigned to the d-block as the heavier analogs of scandium and yttrium, whereas lanthanum and actinium should be considered as the first members of the f-block with irregular configurations. This update is embedded within a detailed analysis of Lavelle’s abortive 2008 attempt to discredit this suggestion.

As targeted proteins that move within the cell, the steroid receptors have become very useful probes for understanding the linked phenomena of protein folding and transport. From the study of steroid receptor‐associated proteins it has become clear over the past two years that these receptors are bound to a multiprotein complex containing at least two heat shock proteins, hsp90 and hsp56. Attachment of receptors to this complex in a cell‐free system appears to require the protein unfolding/folding activity of a third (...) heat shock protein, hsp70. Like the oncogenic tyrosine kinase pp60src, steroid receptors bind to this complex of chaperone proteins at the time of their translation. Binding of the receptor to the hsp90 component of the system occurs through the hormone binding domain and is under strict hormonal control. The hormone binding domain of the receptor acts as a transferable regulatory unit that confers both tight hormonal control and hsp90 binding onto chimaeric proteins. The model of folding and transport being developed for steroid receptors leads to some general suggestions regarding the folding and transport of targeted proteins in the cell. (shrink)

This article examines the ethics of resource allocation by newspaper management. The notion of quality is used to link ethics and economics in publishing, and a quantitative standard of moral behavior in budgetary policy is offered.

If forced to state Feuerbach’s philosophical genealogy, one would have to say that he was son of Hegel, father of Marx, and half-brother of Comte. In his own day he had many a celebratory and many a vilifier. His philosophy has received very little direct treatment in the English language. Feuerbach’s contribution was in his writings on religion and philosophy, each of them a manifesto to humanity, telling us that the desires of men can be satisfied here below. The object (...) of this book, first published in 1941, is twofold. It is its intention to pay humble tribute to a little understood philosopher whose stature grows with the years, and in so doing perhaps to provide a key to the question of religion and personal immortality for those who reject philosophical idealism and a personal God.

No existing conditional semantics captures the dual role of 'if' in embedded interrogatives — 'X wonders if p' — and conditionals. This paper presses the importance and extent of this challenge, linking it to cross-linguistic patterns and other phenomena involving conditionals. Among these other phenomena are conditionals with multiple 'if'-clauses in the antecedent — 'if p and if q, then r' — and relevance conditionals — 'if you are hungry, there is food in the cupboard'. Both phenomena are shown to (...) be problematic for existing analyses. Surprisingly, the decomposition of conditionals needed to capture the link with interrogatives provides a new analysis that captures all three phenomena. The model-theoretic semantics offered here relies on a dynamic conception of meaning and compositionality, a feature discussed throughout. (shrink)

Over the past two decades, the understanding of the roles of vitamin D has expanded to include many nonskeletal effects such as reduced risk of acute respiratory tract infections, autoimmune diseases, cancer, cardiovascular disease, diabetes mellitus, neurological diseases, and adverse pregnancy and birth outcomes. The role of vitamin D for optimal health is well known in Western developed countries but less so in Central Asian countries. This narrative review compares the status of vitamin D between Central Asian countries and Northern (...) European countries. The analysis also summarizes the evidence for the beneficial effects of vitamin D and recommendations for Central Asian countries. (shrink)
