What is the role of human agency in Friedrich Hayek's thought? This volume situates Hayek's writing as it relates to economic organization and activity, particularly to assess what role Hayek assigns to leaders in determining economic progress.

In his [1], David Berlinski explores, among other things, both what could be called a “sophisticated” and a “basic” analogy between languages and the genetic code. The basic analogy stems from the observation that the relationship between English and “Morse” appears to be formally similar to the relationship between DNA and protein. That is, just as sentences of the English language can be encoded into Morse, sequences of bases within strands of DNA are “transcribed” into polypeptides. To some, this “basic” (...) analogy.

Plant protection problems are simulated by a system of ordinary differential equations with given initial conditions. The sensitivity and resistance of pathogen subpopulations to fungicide mixtures, fungicide weathering, plant growth, etc. are taken into consideration. The system of equations is solved numerically for each set of initial conditions and parameters of the disease and fungicide applications. Optimization algorithms were investigated and a computer program was developed for optimization of these solutions. 14 typical cases of the disease were simulated and optimized (...) in order to determine optimal fungicide treatments. The optimized strategy for fungicide application differs considerably from the commonly used method and seems to be an important new principle in plant protection. The approach developed in this study may be useful for a wide spectrum of purposes in the simulation of leaf diseases. It may also help the biologist to decrease or pinpoint experimental work and analyze its results and is perspective for plant disease control. (shrink)

‘Where have you been?’ I expect philosophers to ask me this when I tell them that this paper is on the Gettier Problem. I found it difficult to participate in the discussion of the problem until now because instead of wanting to consider what could be done to revive the project of identifying necessary and conditions for knowledge after the apparent damage done to it by Gettier counter-examples, I wanted to question the legitimacy of the project itself.

The Liar Paradox is a philosophical bogyman. It refuses to die, despite everything that philosophers have done to kill it. Sometimes the attacks on it seem little more than expressions of positivist petulance, as when the Liar sentence is said to be nonsense or meaningless. Sometimes the attacks are based on administering to the Liar sentence arbitrary if not unfair tests for admitting of truth or falsity that seem designed expressly to keep it from qualifying. Some philosophers have despaired of (...) ever beating the Liar; so concerned have they been about the threat posed by the Liar that they have introduced legislation to exclude the Liar sentence and anything like it.

Much anthropocentric environmental argument is limited by a narrow conception of how humans can benefit from nature. E. O. Wilson defends a more robust anthropocentric environmentalism based on a broader understanding of these benefits. At the center of his argument is the biophilia hypothesis according to which humans have an evolutionarily crafted, aesthetic and spiritual affinity for nature. However,the “biophilia hypothesis” covers a variety of claims, some modest and some more extreme. Insofar as we have significant evidence for biophilia, it (...) favors modest versions which do not support a particularly robust anthropocentric environmental ethic. A significantly more robust environmental ethic requires the most extreme version of the biophilia hypothesis, for which there is the least evidence. (shrink)

Using data from a randomized field experiment within a Deliberative Poll, this paper examines deliberation’s effects on both policy attitudes and the extent to which ordinal rankings of policy options approach single-peakedness (a help in avoiding cyclical majorities). The setting was New Haven, Connecticut, and its surrounding towns; the issues were airport expansion and revenue sharing – the former highly salient, the latter not at all. Half the participants deliberated revenue sharing, then the airport; the other half the reverse. This (...) split-half design helps distinguish the effects of the formal on-site deliberations from those of other aspects of the treatment. As expected, the highly salient airport issue saw only a slight effect, while much less salient revenue-sharing issue saw a much larger one. (shrink)

This handbook unites leading scholars from around the world in exploring anarchism as a political ideology, from an examination of its core principles, an analysis of its history, and an assessment of its contribution to the struggles that face humanity today. Grounded in a conceptual and historical approach, each entry charts what is distinctive about the anarchist response to particular intellectual, political, cultural and social phenomena, and considers how these values have changed over time. At its heart is a sustained (...) process of conceptual definition and an extended examination of the core claims of this frequently misunderstood political tradition. It is the definitive scholarly reference work on anarchism as a political ideology, and should be a crucial text for scholars, students, and activists alike. (shrink)

This paper is about the mode of being of names. The paper begins by explaining why the joke is on commentators who see Lewis Carroll's White Knight as applying the use/mention distinction. Then it argues that the real problem with the distinction is that the idea that names are used to mention what they name depends on mistakenly conceiving of language as existing autonomously; and that philosophers have this conception because they fail to appreciate what they are doing when they (...) philosophise about language. This failure also explains why philosophers mistakenly think of any manifestation of a name as a (physical) token. (shrink)

Frank Ebersole's extraordinary investigations of certain key philosophical ideas behind problems in epistemology and metaphysics are the subject of this article-review. I have resisted providing what many readers will expect me to provide, namely, a critical examination of his philosophical methodology. I do question his unwilligness to say why his investigations only yield I negative results, and I do have something to say about classifying him as an ordinary language philosopher. However, my main focus is on trying to engage critically (...) with what he actually does in his work. To this end, I provide a narrative of the investigation he carries out into the possibility of comparing the objects of perception and dreams, and I cite other works of his in support of my understanding of that investigation. Although one of his lengthiest essays seems to be devoted to an anticipation of an objection to his approach, I explain why even there he is not concerned with the question of why he always seems to get negative results. After suggesting why some of his later essays seem to be so hard to read, I conclude by saying something about what I take to be his achievement. (shrink)

An argumentative passage that might appear to be an instance of denying the antecedent will generally admit of an alternative interpretation, one on which the conditional contained by the passage is a preface to the argument rather than a premise of it. On this interpretation. which generally is a more charitable one, the conditional plays a certain dialectical role and, in some cases, a rhetorical role as welL Assuming only a very weak principle of exigetical charity, I consider what it (...) would take in a given case to justify accepting the less charitable interpretation. I then present evidence that those conditions are seldom met. Indeed, I was unable to find a single published argument that can justifiably be charged with denying the antecedent. (shrink)

Biologists frequently draw on ideas and terminology from engineering. Evolutionary systems biology—with its circuits, switches, and signal processing—is no exception. In parallel with the frequent links drawn between biology and engineering, there is ongoing criticism against this cross-fertilization, using the argument that over-simplistic metaphors from engineering are likely to mislead us as engineering is fundamentally different from biology. In this article, we clarify and reconfigure the link between biology and engineering, presenting it in a more favorable light. We do so (...) by, first, arguing that critics operate with a narrow and incorrect notion of how engineering actually works, and of what the reliance on ideas from engineering entails. Second, we diagnose and diffuse one significant source of concern about appeals to engineering, namely that they are inherently and problematically metaphorical. We suggest that there is plenty of fertile ground left for a continued, healthy relationship between engineering and biology. (shrink)

This paper examines Robert Fogelin's suggestion that there may be deep disagreements, where no argument can address what is at issue. A number of possible bases for Fogelin's position are considered and rejected: people sometimes do not have enough in common for reasons to count as reasons; doubt is possible only against the background of framework propositions; key premises may be inarguable; argument must occur within a conceptual framework. The paper concludes by reflecting on why it is important to have (...) a point of view when thinking critically about an argument and whether that fact constitutes a limitation as to what can be achieved by critical thinking.

This paper presents three lessons designed to alert students to the setting in which they are learning (the classroom) and the ways in which this setting provides the context for a discourse which is different than everyday discourse. In the first lesson, students examine empirical studies that illustrate how being in a classroom significantly changes how one reasons about even the most basic logical relationships. In the second lesson, Levi critiques an imaginative way of teaching logic that, while appearing (...) to call on students to use critical reasoning skills they already possess, still fails to take into account its setting. In the final lesson, students translate an editorial into the form of declarative sentences, ordered as premises and a conclusion. Students are prompted to consider what is lost in this rendering and how it distorts the original argument, after which a more successful strategy for paraphrasing and evaluating arguments is attempted. These lessons aim to teach students to think for themselves by encouraging them not to learn logic by wrote, but to see its lessons as tools whose very applicability to real life is something they must critically evaluate.

One problem for any utilitarian alternative to act utilitarianism, such as rule utilitarianism, is the feeling that act utilitarianism is the most natural form of utilitarianism. Other forms seem unmotivated, inconsistent, or irrational. This argument is found in Smart, Foot and Slote. It turns on the assumption that utilitarianism must be motivated by the "teleological motivation," the idea that one must derive one's entire moral theory from the notion of the good. I respond that act utilitarianism itself has a problem (...) from the point of view of the teleological motivation, a problem solved, surprisingly, by several utilitarian alternatives including rule utilitarianism.

My impulse when I decided to collect into a single volume the essays on topics in logical theory and related subjects that I have written in the last fifteen years was to borrow from the title of a work by Sextus Empiricus, and call my collection "Against the Logicians." Although the essays address a variety of problems that interest me, the thread that runs through them is a scepticism about how logicians see things. So, the title appealed to me. However, (...) I had second thoughts and chose instead a title of one of my own essays, "In Defense of Informal Logic", which emphasizes my support for other approaches. Although my criticisms of logical theory are designed to cut deeply, I do not want to be unresponsive to the needs that it is supposed to satisfy. However, my position that we have adequate resources for critically analyzing a particular argument and 00 not need a theory of argumentation, will not completely satisfy those who think that there is a need for it. So, I want them to know that I am taking their concerns seriously. (shrink)

Philosophers should forget what they think they know about divine assistance, power, control, up‐to‐usness, freedom‐from and free will, when it comes to alcoholism, given what Alcoholics Anonymous (AA) says. Alcoholics will never be free of their alcoholism; although it is up to them to acknowledge their powerlessness over alcohol, often that is not possible until they hit bottom, and even then they might not acquire the power of powerlessness without help from a Higher Power. After explaining and defending these insights (...) of AA, the unwarranted assumptions behind how philosophers (and others) criticise them are identified. (shrink)

This paper is a critique of certain arguments given by the Milindapanha and Jay Garfield for the conventional nature of reality or existence. These arguments are of interest in their own right. They also are significant if they are presumed to attack an obstacle we all face in achieving non-attachment, namely, our belief in the inherent or substantial existence of ourselves and the familiar objects of our world. The arguments turn on a distinction between these objects, and some other way (...) of conceiving of them, in terms of which their conventional existence becomes apparent. After the distinction and the arguments that depend on it are shown to be problematic, the paper concludes with some reflections on the doctrine of skillful means and its applicability to Buddhist philosophical argument.

This paper suggests that the flaw in the enthymeme approach to argument analysis is in the requirement, as I come to formulate it, that an argument be restated as a premises-and-conclusion sequence. The paper begins by investigating how logicians show that there are problems with the enthymeme approach. That investigation reveals a failure on the part of logicians to appreciate the importance of the rhetorical context of an argument. This failure, it is argued, is a consequence of what I refer (...) to as the Premise-Conclusion Requirement. (shrink)

Philippa Foot's book, Natural Goodness, involves a large project including a theory of natural goodness, a theory of the virtues, and a theory of practical rationality. Natural goodness is the foundation for the rest and is used to support a more or less traditional list of the virtues and a theory of reasons for action. Though Foot's doctrine of natural goodness may provide an account of some sort of goodness, I argue that it is not adequate as a foundation for (...) practical rationality or as a defense of more or less traditional virtues.

This paper objects to treating begging the question as circular reasoning. It argues that what is at issue in the argument is not to be confused with the claim or position that the arguer is adopting, and that logicians from Aristotle on give the wrong definition and have difficulty making sense of the fallacy because they try to define it in terms of how an argument is defined by logical theory - as a sequence consisting of premises followed by a (...) conclusion. That the problematic about begging the question depends on treating an argument as a context-less sequence of statements seems to be anticipated by the pragma-dialectical approach. The paper offers a critique of this dialogical approach, as exemplified by Douglas Walton in his recent book on begging the question, on the grounds that it raises more problems than it solves. It concludes with the suggestion that what is really at issue in discussions of begging the question is the need for a theory of fallacy. (shrink)

Weiss, Propen, and Reid gather a diverse group of scholars to analyze the growing obsolescence of the human-object dichotomy in today's world. In doing so, Design, Mediation, and the Posthuman brings together diverse disciplines to foster a dialog on significant technological issues pertinent to philosophy, rhetoric, aesthetics, and science.
