APA PsycNET abstract: This is the first volume of a two-volume work on Probability and Induction. Because the writer holds that probability logic is identical with inductive logic, this work is devoted to philosophical problems concerning the nature of probability and inductive reasoning. The author rejects a statistical frequency basis for probability in favor of a logical relation between two statements or propositions. Probability "is the degree of confirmation of a hypothesis (or conclusion) on the basis of some given evidence (...) (or premises)." Furthermore, all principles and theorems of inductive logic are analytic, and the entire system is to be constructed by means of symbolic logic and semantic methods. This means that the author confines himself to the formalistic procedures of word and symbol systems. The resulting sentence or language structures are presumed to separate off logic from all subjectivist or psychological elements. Despite the abstractionism, the claim is made that if an inductive probability system of logic can be constructed it will have its practical application in mathematical statistics, and in various sciences. 16-page bibliography.

"Its publication should be a major event for cognitive linguistics and should pose a major challenge for cognitive science. In addition, it should have repercussions in a variety of disciplines, ranging from anthropology and psychology to epistemology and the philosophy of science.... Lakoff asks: What do categories of language and thought reveal about the human mind? Offering both general theory and minute details, Lakoff shows that categories reveal a great deal."—David E. Leary, American Scientist.

A comprehensive introduction to current research on the psychology of concept formation and use.

Ancients and moderns alike have constructed arguments and assessed theories on the basis of common sense and intuitive judgments. Yet, despite the important role intuitions play in philosophy, there has been little reflection on fundamental questions concerning the sort of data intuitions provide, how they are supposed to lead us to the truth, and why we should treat them as important. In addition, recent psychological research seems to pose serious challenges to traditional intuition-driven philosophical inquiry. Rethinking Intuition brings together a (...) distinguished group of philosophers and psychologists to discuss these important issues. Students and scholars in both fields will find this book to be of great value. (shrink)

UNCLEAR as it is, the traditional doctrine that the notion "meaning" possesses the extension/intension ambiguity has certain typical consequences. The doctrine that the meaning of a term is a concept carried the implication that mean- ings are mental entities. Frege, however, rebelled against this "psy- chologism." Feeling that meanings are public property-that the same meaning can be "grasped" by more than one person and by persons at different times-he identified concepts (and hence "intensions" or meanings) with abstract entities rather than (...) mental entities. However, "grasping" these abstract entities was still an individual psychological act. None of these philosophers doubted that understanding a word (knowing its intension) was just a matter of being in a certain psychological state (somewhat in the way in which knowing how to factor numbers in one's head is just a mat- ter of being in a certain very complex psychological state).

Concepts: Core Readings traces the develoment of one of the most active areas of investigation in cognitive science. This comprehensive volume brings together the essential background readings on concepts from philosophy, psychology, and linguistics, while providing a broad sampling of contemporary research. The first part of the book centers around the fall of the Classical Theory of Concepts in the face of attacks by W.V.O. Quine, Ludwig Wittgenstein, Eleanor Rosch, and others, emphasizing the emergence and development of the Prototype Theory (...) and the controversies it spurred. The second part surveys a broad range of contemporary theories—Neoclassical Theories, the Prototype Theory, the Theory-Theory, and Conceptual Atomism. (shrink)

The purpose of this book is to clarify the concept of definition and improve defining activities.

Modern empiricism has been conditioned in large part by two dogmas. One is a belief in some fundamental cleavage between truths which are analytic, or grounded in meanings independently of matters of fact and truths which are synthetic, or grounded in fact. The other dogma is reductionism: the belief that each meaningful statement is equivalent to some logical construct upon terms which refer to immediate experience. Both dogmas, I shall argue, are ill founded. One effect of abandoning them is, as (...) we shall see, a blurring of the supposed boundary between speculative metaphysics and natural science. Another effect is a shift toward pragmatism. (shrink)

In this paper, I take a critical stance on the emerging field of nanoethics. After an introductory section, “Conceptual Foundations of Nanotechnology” considers the conceptual foundations of nanotechnology, arguing that nanoethics can only be as coherent as nanotechnology itself and then discussing concerns with this latter concept; the conceptual foundations of nanoethics are then explicitly addressed in “Conceptual Foundations of Nanoethics”. “Issues in Nanoethics” considers ethical issues that will be raised through nanotechnology and, in “What’s New?”, it is argued that (...) none of these issues is unique to nanotechnology. In “It’s a Revolution!”, I express skepticism about arguments which hold that, while the issues themselves might not be unique, they nevertheless are instantiated to such a degree that extant moral frameworks will be ill-equipped to handle them. In “What’s Different?”, I draw plausible distinctions between nanoethics and other applied ethics, arguing that these latter might well identify unique moral issues and, as such, distinguish themselves from nanoethics. Finally, in “What Now?”, I explore the conclusions of this result, ultimately arguing that, while nanoethics may fail to identify novel ethical concerns, it is at least the case that nanotechnology is deserving of ethical attention, if not a new associative applied ethic.

Risk management of nanotechnology is challenged by the enormous uncertainties about the risks, benefits, properties, and future direction of nanotechnology applications. Because of these uncertainties, traditional risk management principles such as acceptable risk, cost–benefit analysis, and feasibility are unworkable, as is the newest risk management principle, the precautionary principle. Yet, simply waiting for these uncertainties to be resolved before undertaking risk management efforts would not be prudent, in part because of the growing public concerns about nanotechnology driven by risk perception (...) heuristics such as affect and availability. A more reflexive, incremental, and cooperative risk management approach is required, which not only will help manage emerging risks from nanotechnology applications, but will also create a new risk management model for managing future emerging technologies.

Practical methods are introduced for the construction of definitions, both for philosophical purposes and for uses in other disciplines. The structural and contentual requirements on definitions are clarified. It is emphasized that the development of a definition should begin with careful choice of a primary definiendum, followed by the selection of appropriate variables for the definition. Two methods are proposed for the construction of the definiens, the case list method and the method of successive improvements. Four classes of concepts are (...) discussed that are particularly difficult to define: vague concepts, value-laden concepts, controversial concepts, and inconsistent concepts. (shrink)

There is little doubt that the development and commercialisation of nanotechnologies is challenging traditional state-based regulatory regimes. Yet governments currently appear to be taking a non-interventionist approach to directly regulating this emerging technology. This paper argues that a large regulatory toolbox is available for governing this small technology and that as nanotechnologies evolve, many regulatory advances are likely to occur outside of government. It notes the scientific uncertainties facing us as we contemplate nanotechnology regulatory matters and then examines the notion (...) of regulation itself, suggesting new ways to frame our understanding of both regulation and the regulatory tools relevant to nanotechnologies. By drawing upon three different conceptual lenses of regulation, the paper articulates a wide range of potential regulatory tools at hand. It also focuses particularly on the ways various tools are currently being used or perhaps may be employed in the future. The strengths and weaknesses characterising these tools is examined as well as the different actors involved. The paper concludes that we will increasingly face debate over what is likely to work most effectively in regulating nano technologies, the legitimacy of these different potential approaches, and the speed at which these different regimes may be employed.

A great deal has been made of the question of whether nano-materials provide a unique set of ethical challenges. Equally important is the question of whether they provide a unique set of regulatory challenges. In the last 18 months, the US Environmental Protection Agency has begun the process of trying to meet the regulatory challenge of nano using the Toxic Substances Control Act (1976)(TSCA). In this central piece of legislation, ‘newness’ is a critical concept. Current EPA policy, we argue, does (...) not adequately (or ethically) deal with the novelty of nano. This paper is an exploration of how to do a better job of accounting for nanomaterials as ‘new.’ We explore three alternative ways that nanomaterials might be made to fall under the TSCA regulatory umbrella. Since nanomaterials are of interest precisely because of the exciting new properties that emerge at the nano-scale, each of these three alternatives must meet what we call the ‘novelty condition’ and avoid what we call the ‘central paradox’ of existing regulatory policy. Failure to meet either of these conditions is a moral failure. We examine both the strengths and weaknesses of each alternative in order to illuminate the conceptual, practical, and moral challenges of novelty. (shrink)

Food is a big business in the EU and nanofood products are beginning to be placed on the market. It is still unclear whether the absence of minimum regulation at a global level promotes or prevents the growth of a market in nanofood. However, the development of an adequate risk management policy in relation to food safety is a key concern for consumers. Importantly, the European Parliament in its 2009 Resolution on “Legal aspects on nanomaterials” called for more in-depth scientific (...) research on the toxicity of compounds in nanomaterials, and for the adoption of an EU definition of nanomaterials for regulatory purposes. Unfortunately, in 2011, nanotechnology led to inconclusive debates in the context of the revision of Novel Food Regulation. General Food Law applies to nanofood in terms of safety requirements, and specific rules also apply to food contact materials containing nanoparticles as well as to to additives, vitamins and minerals. The EU legislator also introduced mandatory labelling in respect of products derived from nanotechnologies. The legal framework is evolving according to the so-called “incremental approach”, a governance model that creates the risk of fragmentation. But the main problem is the inconsistent definition of the terms “nanotechnology” and “nanomaterials” when looking at the enforcement of regulations and the provision of a wide range of specific tools for different nanofoods: for example the use of positive lists of authorised substances applying only to food contact materials, additives and supplements. This contribution aims to review the regulations in force in respect to nanofood and novel foods and to highlight the problems that are still unresolved. (shrink)

There is a rapidly expanding field of research on social and ethical interactions with nano-scaled sciences and technologies. An important question is: What does social and ethical research actually mean when it is focussed on technological applications that are largely hypothetical, and a field of science spread out across multiple disciplines and lacking unification? This paper maps early literature in the field of research as a way of answering this question. Our aim is to describe how this field is developing (...) in response to its difficult task, and particularly, to comment on the topics of focus and where there is potential for future development. We present four topical categories, labelled Governance, Perception, Science and Philosophy, and use these as a tool to both map the field and to analyse its development. We find a majority of literature currently focused on issues of governance and perception, and offer suggestions for why this might be so. We then discuss cross-category themes of definition, novelty and interdisciplinarity, highlighting diverse positions and a problematic lack of direct debate. Our conclusion is that the field would benefit from more interaction, cross-referencing and creative research across traditional fields of inquiry. (shrink)

It is often assumed that 'nano' is merely a communication and marketing token. Our inquiry in a number of French laboratories in the field of artificial molecular machines resulted in a quite different picture: a number of researchers are concerned with the definition of nanotechnology. This paper starts from the attempts made by one of the leading figure in the field of molecular machines, Christian Joachim, to draw a clear demarcation between what is 'really nano' and what is not. Probing (...) the epistemological basis of his strategy, we also underline its limits. As this definition is only focused on the prefix 'nano', it would benefit from being completed and enlarged by a definition of 'technology'. We argue that molecular machines belong to the realm of technology in Gilbert Simondon's meaning of this term: a genesis of individualized objects coordinating natural processes and human projects. Finally, this emphasis on the technological dimension of nanotechnology leads to ethical reflections based on the practices of nanotechnology rather than on their potential applications. (shrink)

Nanoscience has enabled the understanding of organisation of the atomic and molecular world. Due to the unique chemical, electronic and magnetic properties nanomaterials have wide applications in the chemical, manufacturing, medical sector etc., Single walled carbon nanotubes, buckyballs, ZnSe quantum dots, TiO 2 nanoparticle based products are nearing commercialisation. Research is on-going worldwide on suitable delivery systems for nanomaterial based drugs. Nanomaterials are highly reactive in biological systems due to the large surface area. While the benefits of nanomaterials are evident (...) there are studies which indicate the potential risk to biological systems. Substances known to be harmless in bulk can be potentially toxic in certain fibrous and nanoparticle form. Risk assessment studies with nanomaterials largely focus on mouse models. There are very few studies on their effects on aquatic species and plants which form the largest in the productivity chain with respect to the ecological pyramid. This study reviews the research done worldwide in the area of risk assessment of nanomaterials, particularly the effects on aquatic and plant systems. Risk assessment is the foundation for regulatory decision making. A general comparison of the regulatory regime in nanotechnology is performed to understand the extent of development. (shrink)
