David Rapoport’s Wave theory of terrorism is one of the most oftencited theories in the literature on terrorist violence. Rapoport is praised for having provided researchers with a universal instrument which allows them to explain the origin and transformation of various historical types of terrorism by applying to them the concept of global waves of terrorist violence driven by universal political impulses. This article, testing the Wave theory against the recent phenomenon of homegrown jihadism in Europe, uncovers this theory’s fundamental (...) weaknesses and questions its real academic and practical value.

According to Aristotelian essentialism, the nature of an organism is constituted of a particular goal-directed disposition to produce an organism typical of its kind. This paper argues—against the prevailing orthodoxy—that essentialism of this sort is indispensable to evolutionary biology. The most powerful anti-essentialist arguments purport to show that the natures of organisms play no explanatory role in modern synthesis biology. I argue that recent evolutionary developmental biology provides compelling evidence to the contrary. Developmental biology shows that one must appeal to (...) the capacities of organisms to explain what makes adaptive evolution adaptive. Moreover, the specific capacities in question are precisely those that, according to Aristotle, constitute the nature of an organism.

There are two general approaches to characterising biological functions. One originates with Cummins. According to this approach, the function of a part of a system is just its causal contribution to some specified activity of the system. Call this the ‘C-function’ concept. The other approach ties the function of a trait to some aspect of its evolutionary significance. Call this the ‘E-function’ concept. According to the latter view, a trait's function is determined by the forces of natural selection. The C-function (...) and E-function concepts are clearly quite different, but there is an important relation between them which heretofore has gone unnoticed. The purpose of this paper is to outline that relation.This is not the first paper to discuss the relation of C-function and E-function. Previous attempts all follow either one of two strategies. The first proposes that the two concepts are ‘unified.’ The other proposes that they are radically distinct and apply to wholly different fields within biology. (shrink)

We distinguish dynamical and statistical interpretations of evolutionary theory. We argue that only the statistical interpretation preserves the presumed relation between natural selection and drift. On these grounds we claim that the dynamical conception of evolutionary theory as a theory of forces is mistaken. Selection and drift are not forces. Nor do selection and drift explanations appeal to the (sub-population-level) causes of population level change. Instead they explain by appeal to the statistical structure of populations. We briefly discuss the implications (...) of the statistical interpretation of selection for various debates within the philosophy of biologythe `explananda of selection' debate and the `units of selection' debate.

Over the past fifteen years there has been a considerable amount of debate concerning what theoretical population dynamic models tell us about the nature of natural selection and drift. On the causal interpretation, these models describe the causes of population change. On the statistical interpretation, the models of population dynamics models specify statistical parameters that explain, predict, and quantify changes in population structure, without identifying the causes of those changes. Selection and drift are part of a statistical description of population (...) change; they are not discrete, apportionable causes. Our objective here is to provide a definitive statement of the statistical position, so as to allay some confusions in the current literature. We outline four commitments that are central to statisticalism. They are: 1. Natural Selection is a higher order effect; 2. Trait fitness is primitive; 3. Modern Synthesis (MS)-models are substrate neutral; 4. MS-selection and drift are model-relative. (shrink)

The concept of the environment appears to be indispensably involved in adaptive explanation. Quite what its role is, however, is a matter of some dispute. The environment is customarily viewed as the dual of the organism; a wholly external, discrete, autonomous cause of evolution. On this view, the external environment is the principal cause of the adaptedness of form, and the determinant of what it is to be an adaptation. I argue that this conception of the environment neither adequately explains (...) nor individuates evolutionary adaptations. Instead, adaptation, properly construed, is an evolutionary response to affordances. The environment, traditionally construed, underdetermines an organism’s affordances. Instead, I argue that the environment takes its place in evolutionary models not as a discrete causal entity, but as an abstraction. (shrink)

There are two competing interpretations of the modern synthesis theory of evolution: the dynamical (also know as ‘traditional’) and the statistical. The dynamical interpretation maintains that explanations offered under the auspices of the modern synthesis theory articulate the causes of evolution. It interprets selection and drift as causes of population change. The statistical interpretation holds that modern synthesis explanations merely cite the statistical structure of populations. This paper offers a defense of statisticalism. It argues that a change in trait frequencies (...) in a population can be attributed only to selection or drift against the background of a particular statistical description of the population. The traditionalist supposition that selection and drift are description‐independent causes of population change leads the dynamical interpretation into a dilemma: it must face a contradiction or accept the loss of explanatory power.

In evolutionary biology changes in population structure are explained by citing trait fitness distribution. I distinguish three interpretations of fitness explanations—the Two‐Factor Model, the Single‐Factor Model, and the Statistical Interpretation—and argue for the last of these. These interpretations differ in their degrees of causal commitment. The first two hold that trait fitness distribution causes population change. Trait fitness explanations, according to these interpretations, are causal explanations. The last maintains that trait fitness distribution correlates with population change but does not cause (...) it. My defense of the Statistical Interpretation relies on a distinctive feature of causation. Causes conform to the Sure Thing Principle. Trait fitness distributions, I argue, do not. *Received July 2009; revised October 2009. †To contact the author, please write to: Department of Philosophy/Institute for the History, Philosophy of Science and Technology, University of Toronto, Victoria College, 91 Charles Street West, Toronto, ON M5S 1K7, Canada; e‐mail: [email protected].

The need to create art is found in every human society, manifest in many different ways across many different cultures. Is this universal need rooted in our evolutionary past? The Art Instinct reveals that it is, combining evolutionary psychology with aesthetics to shed new light on fascinating questions about the nature of art.

In “Sweatshops and Respect for Persons” we argued on Kantian grounds that managers of multinational enterprises (MNEs) have the following duties: to adhere to local labor laws, to refrain from coercion, to meet minimum health and safety standards, and to pay workers a living wage. In their commentary on our paper Sollars and Englander challenge some of our conclusions. We argue here that several of their criticisms are based on an inaccurate reading of our paper, and that none of the (...) remaining criticisms successfully challenge our main arguments.

Psychological individualism is motivated by two taxonomic principles: (i) that psychological states are individuated by their causal powers, and (ii) that causal powers supervene upon intrinsic physiological state. I distinguish two interpretations of individualism--the 'orthodox' and the 'alternative'--each of which is consistent with these motivating principles. I argue that the alternative interpretation is legitimately individualistic on the grounds that it accurately reflects the actual taxonomic practices of bona fide individualistic sciences. The classification of homeobox genes in developmental genetics provides an (...) illustration. When applied to the taxonomy of psychological kinds, alternative individualism has some surprising consequences. In particular, externalist taxonomies of thought are consistent with the alternative interpretation, and hence consistent with individualism. I conclude, on this basis, that the individualism/externalism dispute which has long preoccupied philosophy of psychology is an empty one. (shrink)

According to a prominent view of evolutionary theory, natural selection and the processes of development compete for explanatory relevance. Natural selection theory explains the evolution of biological form insofar as it is adaptive. Development is relevant to the explanation of form only insofar as it constrains the adaptation-promoting effects of selection. I argue that this view of evolutionary theory is erroneous. I outline an alternative, according to which natural selection explains adaptive evolution by appeal to the statistical structure of populations, (...) and development explains the causes of adaptive evolution at the level of individuals. Only together can a statistical theory of selection and a mechanical theory of development explain why populations of organisms comprise individuals that are adapted to their conditions of existence.

Libertarian theories of the normative core of the corporation hold in common the view that is the responsibility of publicity held corporations to return profits to shareholders within the bounds of certain moral side-constraints. Side-constraints may be either weak (grounded in the rules of the game) or strong (grounded in rights). This essay considers libertarian arguments regarding the normative core of the corporation in the context of global capitalism and in the light of actual corporate behavior. First, it is argued (...) the weak side-constraints view is conceptually incoherent when applied in a global context. Second, it is argued that proponents of the libertarian strong side-constraints view lack an adequate theory of rights. Third, both the weak side-constraints view and the strong side-constraints view are shown to be unsatisfactory insofar as they fail to adequately address the coercive power of corporations. The main conclusion of this essay is that a viable libertarian theory of the corporation has yet to be articulated. (shrink)

In this dissertation I develop a general theory of coercion that allows one to distinguish cases of interpersonal coercion from cases of persuasion or manipulation, and cases of institutional coercion from cases of oppression. The general theory of coercion that I develop includes as one component a theory of second-order coercion. Second-order coercion takes place whenever one person intentionally impairs the formation of the second-order desires of another person, or constrains them after their formation, in a way that frustrates or (...) eliminates the possibility of the victim fulfilling certain of his or her first-order desires. The concept of second-order coercion is important because it suggests that a person's autonomy may be violated in ways that have not been previously recognized. In this dissertation I argue that the unique feature of all cases of coercion is that the alternatives available to the victim, with regard to the formation of his or her will, are intentionally constrained by another person in a way that violates the victim's autonomy. A general theory of coercion should be able to explain how institutions may be understood as coercive. I argue that if institutions are understood as social practices maintained for the purpose of achieving some end, then they may be properly understood as capable of coercion. ;This theory of coercion allows me to make two arguments concerning moral responsibility. First, I argue that current discussions of moral responsibility are inadequate because they fail to take seriously the claim that a person may be responsible, at least in part, for having the beliefs and desires that make a particular action a case of coercion. Second, I argue that discussions of moral responsibility are inadequate because they fail to recognize that an agent may not be responsible for the state of his or her will because he or she may have been coerced in a way that has not been previously recognized.

This article argues that the second part of the Parmenides (137-166) consists not only of the well-known logical structure that has been widely studied but also of a great variety of definitions of forms. My aim is to show how these definitions depend on a specific group of closely connected primary forms (i.e., same, different, part, whole). The definitions that Parmenides provides help Socrates overcome his failure in attempting to define forms in the first part of the dialogue.

Reporters and editors share values. If there were no shared values essential to the practice of journalism, it would be impossible to distinguish a journalist from other mass communicators. The set of journalistic values provides the base for an argument that journalists are pluralists, not relativists.

Over the course of human history, the sciences, and biology in particular, have often been manipulated to cause immense human suffering. For example, biology has been used to justify eugenic programs, forced sterilization, human experimentation, and death camps—all in an attempt to support notions of racial superiority. By investigating the past, the contributors to _Biology and Ideology from Descartes to Dawkins_ hope to better prepare us to discern ideological abuse of science when it occurs in the future. Denis R. Alexander (...) and Ronald L. Numbers bring together fourteen experts to examine the varied ways science has been used and abused for nonscientific purposes from the fifteenth century to the present day. Featuring an essay on eugenics from Edward J. Larson and an examination of the progress of evolution by Michael J. Ruse, _Biology and Ideology_ examines uses both benign and sinister, ultimately reminding us that ideological extrapolation continues today. An accessible survey, this collection will enlighten historians of science, their students, practicing scientists, and anyone interested in the relationship between science and culture. (shrink)

The concept of forgery is a touchstone of criticism. If the existence of forgeries — and their occasional acceptance as authentic works of art — has been too often dismissed or ignored in the theory of criticism, it may be because of the forger’s special power to make the critic look ridiculous. Awkward as it is, critics have heaped the most lavish praise on art objects that have turned out to be forged. The suspicion this arouses is, of course, that (...) the critics were led to praise the forgery for the wrong reasons in the first place. Since the aesthetic object as perceived is no different after the revelation that it is forged, the implication to be drawn is that it has previously been critically valued not for its intrinsic aesthetic properties, but because it was believed to be the work of an esteemed artist.

Most shoppers like bargains. Do bargains come at the expense of workers in sweatshops around the world? The authors argue that many large multinational corporations are running the moral equivalents of sweatshops and are not properly respecting the rights of persons. They list a set of minimum standards of safety and decency that they claim all corporations should meet (and that many are not). Finally, they defend their call for improved working conditions by replying to objections that meeting improved conditions (...) will cause greater harm than good, even to the workers themselves. They consider many specifi c corporations and name names and point the finger at various forms of disrespect for persons, along the way. (shrink)

How is it possible to have present memory experiences of things that, being past, are no longer presently experienced? A possible answer to this long-standing philosophical question is what I call the “ideality of time view,” namely the view that temporal succession is unreal. In this paper I outline the basic idea behind Brentano’s version of the ideality of time view. Additionally, I contrast it with Hume’s version, suggesting that, despite significant differences, it can nonetheless be construed as broadly Humean.

What is Life? This is the question asked by Denis Noble in this very personal and at times deeply lyrical book. Noble is a renowned physiologist and systems biologist, and he argues that the genome is not life itself: to understand what life is, we must view it at a variety of different levels, all interacting with each other in a complex web. It is that emergent web, full of feedback between levels, from the gene to the wider environment, that (...) is life. (shrink)

Neste artigo, esboço a ideia por trás da versão de Brentano da visão da idealidade do tempo. Além disso, eu a contrasto com a versão de Hume, sugerindo que, apesar (...) das diferenças significativas, ela pode, no entanto, ser interpretada como humeana em sentido amplo. (shrink)

Barely a decade after the discovery of the chromosomal basis of inheritance, and the articulation of the genetical theory of population change, the gene came to be widely regarded as the fundamental unit of biological organization. This is hardly surprising. The gene concept is a powerful one; it plays a unifying role in our understanding of evolution. Darwin told us that evolution by natural selection occurs in a population when organisms survive, die and reproduce differentially on account of their heritable (...) form. This is a very schematic theory. It requires an account of the process of inheritance and also an account of the generation of phenotype. The gene concept plays a prominent role in explaining, and uniting, these phenomena. Genes are the units of inheritance; they are passed from parents to offspring in reproduction. Moreover, they are seen as units of phenotypic control. Evolutionary biologists often speak of the genome as a program for the production of an organism. Genes also became the elements of which populations are composed. Our best theory of population dynamics—inherited from Fisher, Haldane, and Wright—is a theory of changes in the relative frequencies of gene types. Genes are not just the principal causes of evolutionary change, they are also the units over which evolutionary change is defined and measured. So, at least, the orthodox reading of the Modern Synthesis theory of evolution would have us believe... (shrink)

The Byzantine philosopher Michael Psellos describes in his ethics two kinds of virtue: practical and intellectual virtues. Practical virtues are defined as a middle term between two extremes as is known from the Aristotelian tradition. His innovation is to define also a middle regarding the intellectual virtues. He says that the highest object of knowledge is not graspable for the human intellect because it exceeds his powers. Whoever strives to understand the highest object of knowledge, the essence of god, is (...) determined to fail. Thus, the best objects that the human intellect can contemplate are situated below god, in the “middle”. The concept of the middle is thus present twice in Psellos’ ethics: once in the practical virtues and once in the intellectual virtues. (shrink)

Whenever a structure with a particularly interesting computability-theoretic property is found, it is natural to ask whether similar examples can be found within well-known classes of algebraic structures, such as groups, rings, lattices, and so forth. One way to give positive answers to this question is to adapt the original proof to the new setting. However, this can be an unnecessary duplication of effort, and lacks generality. Another method is to code the original structure into a structure in the given (...) class in a way that is effective enough to preserve the property in which we are interested. In this paper, we show how to transfer a number of computability-theoretic properties from directed graphs to structures in the following classes: symmetric, irreflexive graphs; partial orderings; lattices; rings ; integral domains of arbitrary characteristic; commutative semigroups; and 2-step nilpotent groups. This allows us to show that several theorems about degree spectra of relations on computable structures, nonpreservation of computable categoricity, and degree spectra of structures remain true when we restrict our attention to structures in any of the classes on this list. The codings we present are general enough to be viewed as establishing that the theories mentioned above are computably complete in the sense that, for a wide range of computability-theoretic nonstructure type properties, if there are any examples of structures with such properties then there are such examples that are models of each of these theories.
