Tragic Dilemmas and the Priority of the Moral

My purpose in this paper is to argue that we are not vulnerableto inescapable wrongdoing occasioned by tragic dilemmas. I directmy argument to those who are most inclined to accept tragicdilemmas: those of broadly Nietzschean inclination who reject``modern moral philosophy' in favor of the ethical ideas of theclassical Greeks. Two important features of their project are todeny the usefulness of the ``moral/nonmoral distinction,' and todeny that what are usually classified as moral reasons always oreven characteristically ``trump' nonmoral reasons in anadmirable agent's deliberations.I show critics of modern moral philosophy such as BernardWilliams that their acceptance of tragic dilemmas underminestheir project of denying the moral/nonmoral distinction and thepriority of moral reasons. The possibility of tragic dilemmasrequires an account of practical deliberation in which moralreasons appear as already in-force obligations, with blame andguilt ready to be invoked, while nonmoral reasons appear as merereasons. This makes moral reasons importantly different fromnonmoral reasons in how they achieve their deliberative weight,and also makes them characteristically weightier. Thus,accommodating tragic dilemmas reinforces the moral/nonmoraldistinction and the priority of moral reasons, the very thingsthese critics want to deny. By accepting the possibility oftragic dilemmas, these critics are undermining their own project.The standard normative theories are dead set against tragicdilemmas, and the critics of modern moral philosophy shouldreject tragic dilemmas for the good of their project. Thus we allshould reject tragic dilemmas.     

Young Children's Conception of the Biological World

ABSTRACT— What are the components of children's biological-knowledge system before systematic teaching at school? Can this knowledge system be called naive biology? We propose that young children's biological-knowledge system has at least two essential components—(a) the knowledge needed to identify biological entities and phenomena and (b) teleological and vitalistic causality—and that these components constitute a form of biology. We discuss how this naive biology serves as the basis for performance and learning in socially and culturally important practices, such as health practices and biology instruction.     

Meaning and Interpretation. I

The paper is an attempt at a logical explication of some crucial notions of current general semantics and pragmatics. A general, axiomatic, formal-logical theory of meaning and interpretation is outlined in this paper.In the theory, accordingto the token-type distinction of Peirce, language is formalised on two levels: first as a language of token-objects (understood as material, empirical, enduring through time-and space objects) and then – as a language of type-objects (understood as abstract objects, as classes of tokens). The basic concepts of the theory, i.e. the notions: meaning, denotation and interpretation of well-formed expressions (wfes) of the language are formalised on the type-level, by utilising some semantic-pragmatic primitive notions introduced on the token-level. The paper is divided into two parts.In Part Ia theoryof meaningand denotation is proposed, and in Part II - its expansion to the theory of meaning and interpretation is presented.The meaninga wfe is defined as an equivalence class of the relation possessing the same manner of using types (cf. Ajdukiewicz [1934], Wittgenstein [1953]). The concept of denotation is defined by means of the relation of referring which holds between wfe-types and objects of reality described by the given language. Presented by Wojciech Buszkowski     

Meta-analysis of the reduced relative feedback frequency effect on motor learning and performance

A fundamental motor learning principle conveyed in textbooks is that augmented terminal feedback frequency differentially affects motor learning and performance. The guidance hypothesis predicts that relative to a reduced frequency of feedback, providing learners with feedback following every practice trial enhances practice performance but degrades subsequent motor learning. This change in effectiveness for each relative feedback frequency is called a reversal effect, and because it is thought that practice variables can have distinct impacts on learning and performance, delayed retention tests are considered the gold standard in motor learning research. The objectives of this meta-analysis were to a) synthesize the available evidence regarding feedback frequency, performance, and motor learning to test whether there are significant changes in effectiveness from acquisition and immediate retention to delayed retention, b) evaluate potential moderators of these effects, and c) investigate the potential influence of publication bias on this literature. We screened 1662 articles found in PubMed and PsycINFO databases as well as with reference tracing and a targeted author search. A final sample of 61 eligible papers were included in the primary analysis (k = 75, N = 2228). Results revealed substantial heterogeneity but no significant moderators, high levels of uncertainty, and no significant effect of reduced feedback frequency at any time point. Further, multilevel analyses revealed no evidence of a significant change in effect from acquisition or immediate retention to delayed retention. Z-curve analysis suggested the included studies were severely underpowered. These results suggest that robust evidence regarding feedback frequency and motor learning is lacking.     

Young children discriminate improbable from impossible events in fiction

Can young children discriminate impossible events, which cannot happen in reality, from improbable events, which are unfamiliar but could possibly happen in reality? When asked explicitly to categorize these types of events, 4-year-olds (N = 54) tended to report that improbable events were impossible, consistent with prior results (Shtulman & Carey, 2007). But when presented with stories made up of improbable events, children preferred to continue these stories with additional improbable events rather than with impossible events, demonstrating their sensitivity to the difference between the two types of events. Children were indifferent between continuing these stories with additional improbable events or with ordinary, possible events. Children's differential performance on the story and categorization tasks suggests that they possess some knowledge of the distinction between improbable and impossible but find it difficult to express this knowledge without a supportive context.     

The animate–inanimate distinction in preschool children

This study examined the development of the animate–inanimate (A–I) distinction in relation to other taxonomic categories in early childhood. Four‐ and 5‐year‐old children were administered two tasks measuring knowledge of taxonomic categories at various levels of inclusiveness. Across both matching‐to‐sample and object sorting tasks, the same pattern of categorization development was observed. Mastery of basic‐ and superordinate‐level categories was demonstrated by 4 years of age. Although 5‐year‐old children performed above chance on A–I level categories, their abilities were not as mature as those of adults. Results of this study support and extend previous studies investigating the development of children's understanding of naïve biology during the preschool years.     

What if Wittgenstein could speak Japanese?

ABSTRACT

Wittgenstein’s criticism of the notion of ‘private language’ is related to the putative centrality of “being“ and the ‘subject-predicate’ distinction . However, his efforts would prove to be more fruitful if he could use data from Japanese language. There is a list of Japanese terms to translate ‘being’: sonzai, de-aru, ga-aru, and iru. Among all of their variants, the only subject-predicate-form-related expression is the combination of the ‘Y ga Z aru’-part of ‘X wa Y ga Z aru.’ Hence, Japanese subject-predicate-form-related expressions are not as fundamental as their western counterparts. Insofar as ‘pain’ is concerned, in Japanese, there are two series of expressions on pain: in the first one, the notion of pain is deobjectied and hence immune to subject-predicate logic, while in the second one, it is barely objectified in a limited sense. Hence, a Japanese speaker could avoid the fallacy of attributing subjective sensations to a particular person.     

Revising,Correcting, and Transferring Genes

Abstract

The distinction between germline and somatic gene editing is fundamental to the ethics of human gene editing. Multiple conferences of scientists, ethicists, and policymakers, and multiple professional bodies, have called for moratoria on germline gene editing, and editing of human germline cells is considered to be an ethical “red line” that either never should be crossed, or should only be crossed with great caution and care. However, as research on germline gene editing has progressed, it has become clear that not all germline interventions are alike, and that these differences make a significant moral difference, when it comes to ethical questions about research, regulation, clinical application, and medical justification. In this paper, I argue that, rather than lumping all germline interventions together, we should distinguish between revising, correcting, and transferring genes, and I assess the consequences of this move for the ethics of gene editing.
