Over the past three decades, the Precautionary Principle (PP) has become popular in discussions of public policy, especially in relation to health and environmental policy. Though there are a number of different versions of the principle, the genesis of the idea is that it is better to be safe than sorry. In terms of public policy, proponents of the PP argue that being safe means that, if there is a possibility of harm from a new activity or novel technology, even (...) if the scientific evidence concerning the harm is absent or uncertain, precautionary actions should be taken. In one version or another, the PP has been incorporated into a number of laws and treaties. Yet arguments for the PP are unconvincing, the PP itself is vague and when enacted in law, results in arbitrary regulations that pose a threat to human welfare. As a result, the PP should be rejected as a basis for public policy. (shrink)

Scriven builds a libertarian ethical/political theory on an unusual foundation: Millian utilitarianism. He then applies this theory to humanity’s interactions with nature.

This paper and its sequel “look under the hood” of the usual sorts of proof-theoretic systems for certain well-known intuitionistic and classical propositional modal logics. Section 1 is preliminary. Of most importance: a marked formula will be the result of prefixing a formula in a propositional modal language with a step-marker, for this paper either 0 or 1. Think of 1 as indicating the taking of “one step away from 0.” Deductions will be constructed using marked formulas. Section 2 presents (...) the model-theoretic concepts, based on those in [7], that guide the rest of this paper. Section 3 presents Natural Deduction systems IK and CK, formalizations of intuitionistic and classical one-step versions of K. In these systems, occurrences of step-markers allow deductions to display deductive structure that is covered over in familiar “no step” proof-theoretic systems for such logics. Box and Diamond are governed by Introduction and Elimination rules; the familiar K rule and Necessitation are derived (i.e. admissible) rules. CK will be the result of adding the 0-version of the Rule of Excluded Middle to the rules which generate IK. Note: IK is the result of merely dropping that rule from those generating CK, without addition of further rules or axioms (as was needed in [7]). These proof-theoretic systems yield intuitionistic and classical consequence relations by the obvious definition. Section 4 provides some examples of what can be deduced in IK. Section 5 defines some proof-theoretic concepts that are used in Section 6 to prove the soundness of the consequence relation for IK (relative to the class of models defined in Section 2.) Section 7 proves its completeness (relative to that class). Section 8 extends these results to the consequence relation for CK. (Looking ahead: Part 2 will investigate one-step proof-theoretic systems formalizing intuitionistic and classical one-step versions of some familiar logics stronger than K.). (shrink)

The paper defends Gareth Evan's argument against vague identity "de re" from a criticism that quantum mechanics provides actual counter-examples to its validity. A more general version of Evans's argument is stated in which identity involving properties are not essential and it is claimed that the scientific facts as so far known are consistent with the Evansian thesis that indeterminacy in truth-value must always be due to semantic indecision.

This article first surveys a significant set of issues that are intertwined in asking whether social classes are real. It distinguishes two different notions of class: class as organized social entities and class as types of individuals based on individual characteristics. There is good evidence for some classes as social entities—ruling classes and underclasses in some societies—but other classes in contemporary society are sometimes best thought of in terms of types, not social entities. Implications are drawn for pluralist accounts of (...) social classification and the individualism-holism dispute. (shrink)

Porphyry’s position in the ancient hermeneutic tradition should be considered separately from his place in the Platonic tradition. He shows considerable respect for allegorizing interpreters with links to Pythagoreanism, particularly Numenius and Cronius, prominent sources in On the Cave of the Nymphs. The language of Homer’s Cave passage is demonstrably distinctive, resembling the Shield passage in the Iliad, and such as to suggest an ecphrasis to early imperial readers. Ecphrasis in turn suggested deeper significance for the story. While largely content (...) to follow Numenian trends in interpreting Homer’s cave symbolically and in relation to multiple belief-systems, Porphyry shows occasionally signs of wanting to adhere more closely to Homeric evidence, resorting to symbolic interpretation mainly when no more straightforward truth is on offer.

Tarrant examines whether the relationship between Socrates and his young followers could ever have been treated by Plato in the same fashion as it is treated in the Platonic Theages, where the terminology of synousia is repeatedly applied to it. In minimizing the part played by knowledge and maximizing the role of the divine and of eros, the work creates a "Socrates" who conforms to the educational ideology of the Academy of Polemo in the period 314-270 BC.

Aesthetic internalism claims a link between judgement and motivation: aesthetic judgements bring with them motivations to act in characteristic ways. Critics object that there is a difference between merely liking something and judging it to be aesthetically good, and that it is our likings, not our aesthetic judgements, that motivate us. This paper develops a version of aesthetic internalism that can respond to this criticism. Wholehearted aesthetic judgements are characterized by stability, attention, and motivation. Making such judgements is an important (...) part of a good life, and so at least some aesthetic judgements are motivating. So we have reason to think that this version of aesthetic internalism is true. This paper defends wholehearted aesthetic internalism against objections, and assesses an argument from aesthetic internalism to aesthetic non-cognitivism. While wholehearted aesthetic internalism can only offer qualified support to non-cognitivism, it nonetheless offers a number of fruitful avenues for further work. (shrink)

Originally published 1965. This reprints the 1977 edition which included a new introduction. From the starting point of "popular" charity education, the book traces the dynamic of ideological and social change from the 1790s to the 1830s in terms of attitudes to education and analyzes the range of contemporary opinions on popular education. It also examines some of the channels through which ideas about education were disseminated and became common currency in popular movements.

Federal guidelines require that informed consent be obtained from participants when they are enrolled in a research study. When conducting research with children, the guidelines utilize the term permission to describe parents' agreement to enroll their children in a study. The basic components of consent and permission are well described and identical, with the exception of the person for whom the decision to participate is being made. Beyond permission, when enrolling minor participants in research, affirmative agreement to participate in research (...) or assent must be obtained from the child participants themselves. The concept of children's assent to research, however, is poorly defined, resulting in inconsistency in its pursuit and, consequently, in its utility. The interface between cognitive development, emotional, and social development must be examined as it pertains to this special situation of decision making. For this process to meaningfully protect minors, the assent process must be clarified, decisions regarding parental veto power must be more convincingly justified, and researchers must be better educated and held accountable for the valid execution of this process. Strategies for implementing the assent process more effectively are presented. (shrink)

This article argues that a particular notion of rationality, more exactly a specific notion of legitimate inference, is presupposed by much work in the social sciences to their detriment. The author describes the notion of rationality he has in mind, explains why it is misguided, identifies where and how it affects social research, and illustrates why that research is weaker as a result. The notion of legitimate inference the author has in mind is one that believes inferences are guided by (...) principles that are formal, universal and a priori—that is, that make no substantive, domain-specific empirical assumptions about the world. The author briefly provides a variety of reasons to be skeptical about such principles. Those reasons extend from broad philosophical considerations to quasi-empirical evidence. The author then argues that this notion of inference is involved with both the practice and the content of the social sciences in various ways. In terms of practice, this notion of inference lies behind the way statistical testing is generally done in the social sciences. In terms of content, the author argues that this notion of rationality is invoked, for example, in game theory and in rational expectations macroeconomics. In all cases, use of the formal rationality notion leads social scientists to put more faith in their results than is warranted and thus is an obstacle to doing better social science. (shrink)

Scientific realism is usually a thesis or theses advanced about our best natural science. In contrast, this book defends scientific realism applied to the social and behavioral sciences. It does so, however, by applying the same argument strategy that many have found convincing for the natural sciences, namely, by arguing that we can only explain the success of the sciences by postulating their approximate truth. The particular success that Trout emphasizes for the social sciences is the effective use of statistical (...) testing. Social scientists apply diverse statistical measurement tools to social reality; they are able to refine and improve those measurements over time. The best explanation for such success is that the social sciences give us an approximately true account of some of the laws and entities of the social world. (shrink)
