The precautionary principle is frequently invoked in environmental law and policy, and the debate around the principle indicates that there is little agreement on what 'taking precautions' means. The purpose of the present paper is to provide an improved conceptual foundation for this debate in the form of an explication of the concept of precaution. Distinctions between precaution and two related concepts, prevention and pessimism, are briefly discussed. The concept of precaution is analysed in terms of precautionary actions. It is (...) argued that precautionary actions are implicitly assumed to be precautionary with respect to something, and that this assumption should be made explicit. A definition of a precautionary action involving three necessary and jointly sufficient conditions (intentionality, uncertainty and reasonableness) is proposed, and the implications of this analysis for the debate on the precautionary principle are discussed.

Jason Stanley presents a startling and provocative claim about knowledge: that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests, i.e. by how much is at stake for that person at that time. In defending this thesis, Stanley introduces readers to a number of strategies for resolving philosophical paradox, making the book essential not just for specialists in epistemology but for all philosophers interested in philosophical methodology. Since a (...) number of his strategies appeal to linguistic evidence, it will be of great interest to linguists as well. (shrink)

Knowledge and Lotteries is organized around an epistemological puzzle: in many cases, we seem consistently inclined to deny that we know a certain class of propositions, while crediting ourselves with knowledge of propositions that imply them. In its starkest form, the puzzle is this: we do not think we know that a given lottery ticket will be a loser, yet we normally count ourselves as knowing all sorts of ordinary things that entail that its holder will not suddenly acquire a (...) large fortune. After providing a number of specific and general characterizations of the puzzle, Hawthorne carefully examines the competing merits of candidate solutions. In so doing, he explores a number of central questions concerning the nature and importance of knowledge, including the relationship of knowledge to assertion and practical reasoning, the status of epistemic closure principles, the merits of various brands of scepticism, the prospects for a contextualist account of knowledge, and the potential for other sorts of salience-sensitive accounts. Along the way, he offers a careful treatment of pertinent issues at the foundations of semantics. His book will be of interest to anyone working in the field of epistemology, as well as to philosophers of language. (shrink)

In epistemology, “contextualism” denotes a wide variety of more-or-less closely related positions according to which the issues of knowledge or justification are somehow relative to context. I will proceed by first explicating the position I call contextualism, and distinguishing that position from some closely related positions in epistemology, some of which sometimes also go by the name of “contextualism”. I’ll then present and answer what seems to many the most pressing of the objections to contextualism as I construe it, and (...) also indicate some of the main positive motivations for accepting the view. Among the epistemologists I’ve spoken with who have an opinion on the matter, I think it’s fair to say a majority reject contextualism. However, the resistance has to this point been largely underground, with little by way of sustained arguments against contextualism appearing in the journals,[i] though I have begun to see various papers in manuscript form which are critical of contextualism. Here, I’ll respond the criticism of contextualism that, in my travels, I have found to be the most pervasive in producing suspicion about the view. (shrink)

It is sometimes suggested that new research in such areas as artificial intelligence, nanotechnology and genetic engineering should be halted or otherwise restricted because of concerns about possible catastrophic scenarios. Proponents of such restrictions typically invoke the precautionary principle, understood as a tool of policy formulation, as part of their case. Here I examine the application of the precautionary principle to possible catastrophic scenarios. I argue, along with Sunstein (Risk and Reason: Safety, Law and the Environment. Cambridge University Press, Cambridge, (...) 2002) and Manson (Environmental Ethics, 24: 263–274, 2002), that variants of the precautionary principle that appear strong enough to support significant restrictions on future technologies actually lead to contradictory policy recommendations. Weaker versions of the precautionary principle, which do not have this feature, do not appear strong enough to support restrictions on future technologies. (shrink)

1. I am going to work with an idea from Sellars, that knowledge—at least as enjoyed by rational animals—is a certain sort of standing in the space of reasons. My concern is a familiar philosophical dialectic, which I shall approach in terms of what happens to the Sellarsian idea when the image of standings in the space of reasons undergoes a certain deformation. That it is a deformation is something we can learn from how unsatisfactory the familiar dialectic is.

Much as we would like to conceive empirical thought as rationally grounded in experience, pitfalls await anyone who tries to articulate this position, and ...

It is a commonplace that in making decisions agents often have to juggle competing values, and that no choice will maximise satisfaction of them all. However, the prevailing account of these cases assumes that there is always a single ranking of the agent's values, and therefore no unresolvable conflict between them. Isaac Levi denies this assumption, arguing that agents often must choose without having balanced their different values and that to be rational, an act does not have to be optimal, (...) only what Levi terms 'admissible'. This book explores the consequences of denying the assumption and develops a general approach to decision-making under unresolved conflict. Professor Levi discusses conflicts of value in several domains - those arising in moral dilemmas, the drawing of scientific inferences, decisions taken under uncertainty, and in social choice. In each of these he adapts his theoretical framework, showing how conflict may often be reduced though not always altogether eliminated. (shrink)

In part one, I identify the core logical structure of the precautionary principle and distinguish it from the various key concepts that appear in the many different formulations of the principle. I survey these concepts and suggest a program of further conceptual analysis. In part two, I examine a particular version of the precautionary principle dubbed “the catastrophe principle” and criticize it in light of its similarities to the principle at work in Pascal’s Wager. I conclude with some suggestions for (...) advocates of the precautionary principle who wish their formulation to avoid the pitfalls confronting the catastrophe principle. (shrink)

How do rational minds make contact with the world? The empiricist tradition sees a gap between mind and world, and takes sensory experience, fallible as it is, to provide our only bridge across that gap. In its crudest form, for example, the traditional idea is that our minds consult an inner realm of sensory experience, which provides us with evidence about the nature of external reality. Notoriously, however, it turns out to be far from clear that there is any viable (...) conception of experience which allows it to do the job. The original problem is to show that thought is rationally constrained by external reality. If sensory experience is to provide the solution--in particular, if it is to provide the answer to sceptical challenges--it must therefore meet two criteria. First, it must itself be `receptive'--i.e., appropriately constrained by external reality. Second, it must be the kind of thing that can enter into a logical or rational relationship with belief--it must already be `conceptual,' in other words. In arguing against the idea that anything could serve both roles, Wilfred Sellars termed this conception of experience "the Myth of the Given.". (shrink)

Since a couple of decades, the notion of a precautionary principle plays a central and increasingly influential role in international as well as national policy and regulation regarding the environment and the use of technology. Urging society to take action in the face of potential risks of human activities in these areas, the recent focus on climate change has further sharpened the importance of this idea. However, the idea of a precautionary principle has also been problematised and criticised by scientists, (...) scholars and policy activists, and been accused of almost every intellectual sin imaginable: unclarity, impracticality, arbitrariness and moral as well as political unsoundness. In that light, the very idea of precaution as an ideal for policy making rather comes out as a dead end. On the basis of these contrasting starting points, Christian Munthe undertakes an innovative, in-depth philosophical analysis of what the idea of a precautionary principle is and should be about. A novel theory of the ethics of imposing risks is developed and used as a foundation for defending the idea of precaution in environmental and technological policy making against its critics, while at the same time avoiding a number of identified flaws. The theory is shown to have far-reaching consequences for areas such as bio-, information- and nuclear technology, and global environmental policy in areas such as climate change. The author argues that, while the price we pay for precaution must not be too high, we have to be prepared to pay it in order to act ethically defensible. A number of practical suggestions for precautionary regulation and policy making are made on the basis of this, and some challenges to basic ethical theory as well as consumerist societies, the global political order and liberal democracy are identified.

Jessica Brown effectively contends that Keith DeRose’s latest argument for contextualism fails to rule out contextualism’s chief rival, namely, classic invariantism. Still, even if her position has not been ruled out, the classic invariantist must offer considerations in favor of her position if she is to convince us that it is superior to contextualism. Brown defends classic invariantism with a warranted assertability maneuver that utilizes a linguistic pragmatic principle of relevance. I argue, however, that this maneuver is not as effective (...) as it might be. I propose a different warranted assertability maneuver—one that utilizes a pragmatic principle of strength—that affords a more successful defense of classic invariantism, and that helps to establish that classic invariantism is superior to contextualism.

The precautionary principle (PP) has been criticised for almost every intellectual sin one may imagine: unclarity, impracticability, rigidity, implausibility etc. Recognising the rather obvious fact that there is no such thing as one PP, this paper attempts to address this criticism on a more constructive note than merely view it as forcing us to be "for or against" precaution. This is done by connecting an underlying ethical ideal regarding the imposition of risks present in most formulations of PP to the (...) criticism and use the latter for discussing how such an idea may be plausibly designed and used for underpinning policies that may plausibly be said to express the spirit of PP. It is argued that the most important issue regarding this is to recognise that there is something to the idea that imposing risks on people has a morally significant price, but that we must also acknowledge that taking precautionary measures to avoid or decrease such risks has such a price. The critical issue in the ethics of risk of relevance for PP thus becomes what constitutes a proper price of precaution. It is demonstrated how two simple constraints on this amkes it easy to meet many typical arguments against PP, but also how this issue must be further attacked by means transcending the traditional tools of normative ethics and decision theory, as well as how further reflection along such lines connects PP to issues of international..

The precautionary principle holds that we should not allow scientific uncertainty to prevent us from taking precautionary measures in response to potential threats that are irreversible and potentially disastrous. Critics of the principle claim that it deters progress and development, is excessively risk-aversive and is unscientific. This paper argues that the principle can be scientific provided that the threats addressed by the principle are plausible threats, and the precautionary measures adopted are reasonable. The paper also argues that one may use (...) epistemic criteria, such as consistency, coherence and explanatory power, to determine whether a threat is plausible, and that one may use practical considerations, such as effectiveness, proportionality, cost-effectiveness, realism and consistency, to determine whether a response to a threat is reasonable.
