Tackling grand challenges requires coordination and sustained effort among multiple organizations and stakeholders. Yet research on stakeholder theory has been conceptually constrained in capturing this complexity: existing accounts tend to focus either on dyadic level firm–stakeholder ties or on stakeholder networks within which the focal organization is embedded. We suggest that addressing grand challenges requires a more generative conceptualization of organizations and their constituents as stakeholder systems. Using the metaphor of ballet and insights from dance theory, we highlight four defining (...) dimensions of stakeholder systems (two structural and two dyadic); we proceed to offer a dynamic model of how those dimensions may interact and coevolve. Our metaphor and resulting theory of stakeholder systems are thereby well equipped to incorporate the complexity of tackling grand challenges, where many contemporary stakeholder arrangements are oriented around issues rather than firms.

The principle of limited liability is one of the defining characteristics of modern corporate capitalism. It is also, we argue in this article, a powerful structural source of moral hazard. Engaging in a double conceptual genealogy, we investigate how the concepts of moral hazard and limited liability have evolved and diffused over time. We highlight two parallel but unconnected paths of construction, diffusion, moral contestation, and eventual institutionalization. We bring to the fore clear elective affinities between both concepts and their (...) respective evolution. Going one step further, we suggest that both concepts have come to be connected through time. In the context of contemporary capitalism, limited liability has to be understood, we argue, as a powerful structural source of moral hazard. In conclusion, we propose that this structural link between limited liability and moral hazard is an important explanatory factor of the systemic instability of contemporary capitalism and, as a consequence, of a pattern of recurrent crises that are regularly disrupting our economies and societies.

This book is concerned with the role of intuitions in the justification of philosophical theory. The author begins by demonstrating how contemporary philosophers, whether engaged in case-driven analysis or seeking reflective equilibrium, rely on intuitions as evidence for their theories. The author then provides an account of the nature of philosophical intuitions and distinguishes them from other psychological states. Finally, the author defends the use of intuitions as evidence by demonstrating that arguments for skepticism about their evidential value are either (...) self-defeating or guilty of arbitrary and unjustified partiality towards non-intuitive modes of knowledge.

In this paper, I outline two strands of evidence for the conclusion that the dynamical approach to cognitive science both seeks and provides covering law explanations. Two of the most successful dynamical models—Kelso’s model of rhythmic finger movement and Thelen et al.’s model of infant perseverative reaching—can be seen to provide explanations which conform to the famous explanatory scheme first put forward by Hempel and Oppenheim. In addition, many prominent advocates of the dynamical approach also express the provision of this (...) kind of explanation as a goal of dynamical cognitive science. I conclude by briefly outlining two consequences. First, dynamical cognitive science’s explanatory style may strengthen its links to the so-called “situated” approach to cognition, but, secondly, it may also undermine the widespread intuition that dynamics is related to emergentism in the philosophy of mind.

The concept of empathy has received much attention from philosophers and also from both cognitive and social psychologists. It has, however, been given widely conflicting definitions, with some taking it primarily as an epistemological notion and others as a social one. Recently, empathy has been closely associated with the simulationist approach to social cognition and, as such, it might be thought that the concept’s utility stands or falls with that of simulation itself. I suggest that this is a mistake. Approaching (...) the question of what empathy is via the question of what it is for, I claim that empathy plays a distinctive epistemological role: it alone allows us to know how others feel. This is independent of the plausibility of simulationism more generally. With this in view I propose an inclusive definition of empathy, one likely consequence of which is that empathy is not a natural kind. It follows that, pace a number of empathy researchers, certain experimental paradigms tell us not about the nature of empathy but about certain ways in which empathy can be achieved. I end by briefly speculating that empathy, so conceived, may also play a distinctive social role, enabling what I term ‘transparent fellow-feeling’. (shrink)

A defense of amorality as both philosophically justified and practicably livable. While in synch with their underlying aim of grounding human existence in a naturalistic metaphysics, this book takes both the new atheism and the mainstream of modern ethical philosophy to task for maintaining a complacent embrace of morality. It advocates instead replacing the language of morality with a language of desire. The book begins with an analysis of what morality is and then argues that the concept is not instantiated (...) in reality. Following this, the question of belief in morality is addressed: How would human life be affected if we accepted that morality does not exist? The book argues that at the very least, a moralist would have little to complain about in an amoral world, and at best we might hope for a world that was more to our liking overall. An extended look at the human encounter with nonhuman animals serves as an illustration of amorality’s potential to make both theoretical and practical headway in resolving heretofore intractable ethical problems.

Many phylogenetic systematists have criticized the Biological Species Concept (BSC) because it distorts evolutionary history. While defenses against this particular criticism have been attempted, I argue that these responses are unsuccessful. In addition, I argue that the source of this problem leads to previously unappreciated, and deeper, fatal objections. These objections to the BSC also straightforwardly apply to other species concepts that are not defined by genealogical history. What is missing from many previous discussions is the fact that the Tree (...) of Life, which represents phylogenetic history, is independent of our choice of species concept. Some species concepts are consistent with species having unique positions on the Tree while others, including the BSC, are not. Since representing history is of primary importance in evolutionary biology, these problems lead to the conclusion that the BSC, along with many other species concepts, are unacceptable. If species are to be taxa used in phylogenetic inferences, we need a history-based species concept. (shrink)

Does natural selection explain why individual organisms have the traits that they do? According to "the Negative View," natural selection does not explain why any individual organism has the traits that it does. According to "the Positive View," natural selection at least sometimes does explain why an individual organism has the traits that it does. In this paper, I argue that recent arguments for the Positive View fail in virtue of running afoul of the doctrine of origin essentialism and I (...) demonstrate that other recent defenses of the Negative View depend upon my own for their plausibility.

Moderate rationalists maintain that our rational intuitions provide us with prima facie justification for believing various necessary propositions. Such a claim is often criticized on the grounds that our having reliable rational intuitions about domains in which the truths are necessary is inexplicable in some epistemically objectionable sense. In this paper, I defend moderate rationalism against such criticism. I argue that if the reliability of our rational intuitions is taken to be contingent, then there is no reason to think that (...) our reliability is inexplicable. I also suggest that our reliability is, in fact, necessary, and that such necessary reliability neither admits of, nor requires, any explanation of the envisaged sort. (shrink)

In this paper, we take moral agency to be that context in which a particular agent can, appropriately, be held responsible for her actions and their consequences. In order to understand moral agency, we will discuss what it would take for an artifact to be a moral agent. For reasons that will become clear over the course of the paper, we take the artifactual question to be a useful way into discussion but ultimately misleading. We set out a number of (...) conceptual pre-conditions for being a moral agent and then outline how one should — and should not — go about attributing moral agency. In place of a litmus test for such an agency — such as Allen et al.'s Moral Turing Test — we suggest some tools from the conceptual spaces theory and the unified conceptual space theory for mapping out the nature and extent of that agency.

We present several generalizations of the well-known Kunen inconsistency that there is no nontrivial elementary embedding from the set-theoretic universe V to itself. For example, there is no elementary embedding from the universe V to a set-forcing extension V[G], or conversely from V[G] to V, or more generally from one set-forcing ground model of the universe to another, or between any two models that are eventually stationary correct, or from V to HOD, or conversely from HOD to V, or indeed (...) from any definable class to V, among many other possibilities we consider, including generic embeddings, definable embeddings and results not requiring the axiom of choice. We have aimed in this article for a unified presentation that weaves together some previously known unpublished or folklore results, several due to Woodin and others, along with our new contributions.

The Gap Forcing Theorem, a key contribution of this paper, implies essentially that after any reverse Easton iteration of closed forcing, such as the Laver preparation, every supercompactness measure on a supercompact cardinal extends a measure from the ground model. Thus, such forcing can create no new supercompact cardinals, and, if the GCH holds, neither can it increase the degree of supercompactness of any cardinal; in particular, it can create no new measurable cardinals. In a crescendo of what I call (...) exact preservation theorems, I use this new technology to perform a kind of partial Laver preparation, and thereby finely control the class of posets which preserve a supercompact cardinal. Eventually, I prove the ‘As You Like It’ Theorem, which asserts that the class of κ -directed closed posets which preserve a supercompact cardinal κ can be made by forcing to conform with any pre-selected local definition which respects the equivalence of forcing. Along the way I separate completely the levels of the superdestructibility hierarchy, and, in an epilogue, prove that the notions of fragility and superdestructibility are orthogonal — all four combinations are possible.

Highly concentrated intensive confinement systems have become the norm in agriculture concerning nonhuman animals. These systems have provoked a lively debate from an animal welfare perspective. Sociologists can contribute to this debate by drawing parallels between the institutional regulation of human beings and of animals under confinement. Results of research on the transformation of Canadian hog production from the 1950s to the present—based on the evolution of plans for sow housing produced by the Canada Plan Service—showed a much tighter compression (...) of hog bodies and reproduction in space and time. The prevalence of behavioral stereotypes, however, indicates imperfect animal socialization and reconfiguration. The concept of discipline is a useful perspective that could bridge the gap between the regulations of humans in industrial societies and of pigs in intensive confinement. This concept derived from elements of labor process and Foucauldian and post-humanist theories. (shrink)

Bayesian methods have become among the most popular methods in phylogenetics, but theoretical opposition to this methodology remains. After providing an introduction to Bayesian theory in this context, I attempt to tackle the problem mentioned most often in the literature: the “problem of the priors”—how to assign prior probabilities to tree hypotheses. I first argue that a recent objection—that an appropriate assignment of priors is impossible—is based on a misunderstanding of what ignorance and bias are. I then consider different methods (...) of assigning prior probabilities to trees. I argue that priors need to be derived from an understanding of how distinct taxa have evolved and that the appropriate evolutionary model is captured by the Yule birth–death process. This process leads to a well-known statistical distribution over trees. Though further modifications may be necessary to model more complex aspects of the branching process, they must be modifications to parameters in an underlying Yule model. Ignoring these Yule priors commits a fallacy leading to mistaken inferences both about the trees themselves and about macroevolutionary processes more generally. (shrink)

A phylogeny that allows for lateral gene transfer (LGT) can be thought of as a strictly branching tree (all of whose branches are vertical) to which lateral branches have been added. Given that the goal of phylogenetics is to depict evolutionary history, we should look for the best supported phylogenetic network and not restrict ourselves to considering trees. However, the obvious extensions of popular tree-based methods such as maximum parsimony and maximum likelihood face a serious problem—if we judge networks by (...) fit to data alone, networks that have lateral branches will always fit the data at least as well as any network that restricts itself to vertical branches. This is analogous to the well-studied problem of overfitting data in the curve-fitting problem. Analogous problems often have analogous solutions and we propose to treat network inference as a case of model selection and use the Akaike Information Criterion (AIC). Strictly tree-like networks are more parsimonious than those that postulate lateral as well as vertical branches. This leads to the conclusion that we should not always infer LGT events whenever it would improve our fit-to-data, but should do so only when the improved fit is larger than the penalty for adding extra lateral branches.

Using the lottery preparation, we prove that any strongly unfoldable cardinal $\kappa$ can be made indestructible by all.

Deonna and Teroni’s The Emotions is both an excellent introduction to philosophical work on emotions and a novel defence of their own Attitudinal Theory. After summarising their discussion of the literature I describe and evaluate their positive view. I challenge their theory on three fronts: their claim that emotions are a form of bodily awareness, their account of what makes an emotion correct, and their account of what justifies an emotion.

In its central use “phenomenology” names a movement in twentieth century philosophy. A second use of “phenomenology” common in contemporary philosophy names a property of some mental states, the property they have if and only if there is something it is like to be in them. Thus, it is sometimes said that emotional states have a phenomenology while belief states do not. For example, while there is something it is like to be angry, there is nothing it is like to (...) believe that Paris is in France. Although the two uses of “phenomenology” are related, it is the first which is the current topic. Accordingly, “phenomenological” refers to a way of doing philosophy that is more or less closely related to the corresponding movement. Phenomenology utilizes a distinctive method to study the structural features of experience and of things as experienced. It is primarily a descriptive discipline and is undertaken in a way that is largely independent of scientific, including causal, explanations and accounts of the nature of experience. Topics discussed within the phenomenological tradition include the nature of intentionality, perception, time-consciousness, self-consciousness, awareness of the body and consciousness of others. Phenomenology is to be distinguished from phenomenalism, a position in epistemology which implies that all statements about physical objects are synonymous with statements about persons having certain sensations or sense-data. George Berkeley was a phenomenalist but not a phenomenologist. -/- Although elements of the twentieth century phenomenological movement can be found in earlier philosophers—such as David Hume, Immanuel Kant and Franz Brentano—phenomenology as a philosophical movement really began with the work of Edmund Husserl. Following Husserl, phenomenology was adapted, broadened and extended by, amongst others, Martin Heidegger, Jean-Paul Sartre, Maurice Merleau-Ponty, Emmanuel Levinas and Jacques Derrida. Phenomenology has, at one time or another, been aligned with Kantian and post-Kantian transcendental philosophy, existentialism and the philosophy of mind and psychology. -/- This article introduces some of the central aspects of the phenomenological method and also concrete phenomenological analyses of some of the topics that have greatly exercised phenomenologists.

Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

The use of other animals for human purposes is as contentious an issue as one is likely to find in ethics. And this is so not only because there are both passionate defenders and opponents of such use, but also because even among the latter there are adamant and diametric differences about the bases of their opposition. In both disputes, the approach taken tends to be that of applied ethics, by which a position on the issue is derived from a (...) fundamental moral commitment. This commitment in turn depends on normative ethics, which investigates the various moral theories for the best fit to our moral intuitions. Thus it is that the use of animals in biomedical research is typically defended by appeal to a utilitarian theory, which legitimates harm to some for the greater good of others; while the opposition condemns that use either by appeal to the same theory, but disagreeing about the actual efficacy of animal experimentation, or by appeal to an alternative theory, such as the right of all sentient beings not to be exploited. Unfortunately, the normative issue seems likely never to be resolved, hence leaving the applied issue in limbo. The present essay seeks to circumvent this impasse by dispensing altogether with any moral claim or argument, thereby cutting the Gordian knot of animal ethics with a meta-ethical sword. The alternative schema defended is simply to advance relevant considerations, whereupon “there is nothing left but to feel.” In a word, motivation replaces justification. (shrink)

I argue for the view that some we-thoughts are immune to error through misidentification (IEM) relative to the first-person plural pronoun. To prepare the ground for this argument I defend an account of the semantics of ‘we’ and note the variety of different uses of that term.

We examined effects of exposure to unreportable images of spiders on approach towards a tarantula. Pretests revealed awareness of the stimuli was at chance. Participants high or low on fear of spiders were randomly assigned to receive computer-generated exposure to unreportable pictures of spiders or outdoor scenes. They then engaged in a Behavioral Approach Task with a live tarantula. Non-fearful participants completed more BAT items than spider-fearful individuals. Additionally, as predicted, a significant interaction = 5.12, p < .03) between fear (...) of spiders and stimulus demonstrated that spider-fearful participants exposed to spiders completed more BAT items than spider-fearful participants exposed to control stimuli . The findings support the hypothesis that exposure to unreportable feared stimuli promotes approach towards the feared object. Future research and clinical implications were discussed. (shrink)

If the Wholeness Axiom wa $_0$ is itself consistent, then it is consistent with v=hod. A consequence of the proof is that the various Wholeness Axioms are not all equivalent. Additionally, the theory zfc+wa $_0$ is finitely axiomatizable.

The experimental laboratory can be a horror house for rats, monkeys, and other nonhuman animals. Yet their use in this setting is usually reported in a routine manner in publications that discuss the results. These contentions are illustrated with an analysis of the way animal evidence is presented in David J. Linden’s recent book, The Accidental Mind: How Brain Evolution Has Given Us Love, Memory, Dreams, and God (Harvard University Press, 2007). The article concludes with a call to science authors (...) to acknowledge formally in their written work the ethical significance of such use of nonhuman animals. (shrink)

This paper draws a distinction between two possible understandings of the DEEDS (Dynamical, Embodied, Extended, Distributed and Situated) approach to cognition. On the one hand, the DEEDS approach may be interpreted as making a metaphysical claim about the nature and location of cognitive processes. On the other hand, the DEEDS approach may be read as providing a methodological prescription about how we ought to conduct cognitive scientific research. I argue that the latter, methodological, reading shows that the DEEDS approach is (...) pursuitworthy independently of an assessment of the truth of the metaphysical claim. Understood in this way, the DEEDS approach may avoid some of the objections that have been levelled against it. (shrink)

Rereading Renée C. Fox's “A Sociological Perspective on Organ Transplantation and Hemodialysis,” published in 1970, one is likely to be struck more by continuity than by change. The most pressing of the social, policy, and ethical concerns that Fox raised remain problematic fifty years later. We still struggle with scientific and clinical uncertainty, with the boundary between experimentation and therapy, and with the cost of organ replacement therapies and disparities in how they are allocated. We still have an imperfect understanding (...) of transplant immune responses. We still debate when a potential donor “actually” dies, and we still seem to think better empirical criteria could harmonize the diverse religious, cultural, and socioeconomic values of patients, providers, third‐party payers, and policy‐makers. Organ transplantation was for Fox both a particular case unfolding in time and an entryway for discussing the difficult moral questions presented by many new medical technologies in a context of high demand and limited resources.

Previous papers on ethics consultation in medicine have taken a positivistic approach and lack critical scrutiny of the psychosocial, political, and moral contexts in which consultations occur. This paper discusses some of the contextual factors that require more careful research. We need to know more about what prompts and inhibits consultation, especially what factors effectively prevent house officers and nonphysicians from requesting consultation despite perceived moral conflict in cases. The attitudes and institutional power of attending medical staff seem important, especially (...) where innovative interventions raise ethical questions. Ethics consultants also need to address the thorny problems of the origin(s) of the consultant's authority, whistleblowing, conflicts of interest that affect the consultant, persistently poor communications in hospitals, systemic inequity in the availability or quality of services for some, and the standing of the consultant's recommendations, including their appearance in the patient's medical record.

Moderate rationalism is the view a person's having a rational intuition that p prima facie justifies them in believing that p. It has recently been argued that moderate rationalism requires empirical support and, furthermore, that suitable empirical support would suffice to convince empiricists to abandon their opposition to rationalism. According to one argument, the causal requirement argument, empirical evidence is necessary in order to justify the claim that any actual token belief is based on rational intuition and moderate rationalism requires (...) such a claim for its justification. According to a second argument, the reliability argument, empirical evidence is necessary in order to justify the claim that a putative source of evidence is reliable and moderate rationalism requires such a claim for its justification. According to a third argument, the empirical case argument, certain sorts of empirical evidence would be dialectically sufficient to resolve the traditional dispute between empiricists and rationalists in the rationalists' favor. Against the causal requirement argument, I maintain that the core doctrines of moderate rationalism are not hostage to causal claims and that such causal claims as may be plausibly part of other recognizably rationalist doctrines can be justified on broadly non-empirical grounds. Against the reliability argument, I show that no empirical evidence is required to justify belief in the reliability of rational intuition. Against the empirical case argument, I argue that the envisioned empirical support for moderate rationalism should not convince any traditional empiricist. (shrink)

The traditional problems of epistemology have often been thought to be properly solved only by the provision of an argument, with premises justified by rational intuition and introspection, for the probable truth of our beliefs in the problematic domains. Following the lead of Thomas Reid, a sizable number of contemporary epistemologists, including many proponents of so-called "Reformed epistemology" regarding religious belief, reject as arbitrary the preferential treatment of reason and introspection implicit in the traditional view of the problems. These "Reidians" (...) insist that the traditional problems cannot be solved in the expected manner, but they go on to suggest that this result is of little significance because similar skeptical questions can be raised regarding a priori and introspective justification. After making clear the significance of the Reidian objection, I endeavor to defend the traditional preference for rational intuition over our other sources of belief by demonstrating that the usual skeptical worries cannot be equally raised against a priori justification. Then, after a brief consideration of some unduly neglected passages in Reid's writings in which he appears to concede that the traditional partiality to reason and introspection is not, in fact, arbitrary, I argue that it is the Reidians who are guilty of arbitrary partiality.

The standard interpretations of Foucault's intellectual biography usually present Sartre as his major adversary. Though it would be difficult to underestimate the importance of Sartre for Foucault's development, this paper argues that Foucault was involved in an even more intense and deeper contest with Freud. Indeed, Freud was Foucault's principal adversary and, throughout his career, Foucault was trying to formulate a counter-project to psychoanalysis. The author attempts to demonstrate this claim by examining Foucault's early psychological writings, Madness and Civilization, his (...) encounter with Kant in The Order of Things and The History of Sexuality. He argues, moreover, that Foucault had articulated a project, namely, 'the dialogue with unreason', which not only could have provided a meeting point for his project and Freud's but can still provide a way of getting beyond the exhausted debate between the advocates of the Enlightenment and the Anti-Enlightenment. Because he could never give up the temptation to valorize transgression, however, Foucault was unable to pursue the dialogue with unreason in a systematic way. Key Words: Foucault • Freud • psychoanalysis • reason. (shrink)

The distinction between taxonomic plant geography and ecological plant geography was never absolute: it would be historically inaccurate to portray them as totally divergent. Taxonomists occasionally borrowed ecological concepts, and ecologists never completely repudiated taxonomy. Indeed, some botanists pursued the two types of geographic study. The American taxonomist Henry Allan Gleason (1882–1975), for one, made noteworthy contributions to both. Most of Gleason's research appeared in short articles, however. He never published a major synthetic work comparable in scope or influence to (...) the ecological texts of Clements, Schimper, and Warming.Despite exceptions such as Gleason, most plant geographers throughout the twentieth century have emphasized the distinction between ecological and taxonomic plant geographies. Why have these distinct traditions developed? In his book Geographical Ecology, Robert MacArthur has suggested a psychological explanation for the dichotomy: “Unraveling the history of a phenemenon has always appealed to some people and describing the machinery of the phenomenon to others... The ecologist and physical scientist tend to be machinery oriented, whereas paleontologists and most biogeographers tend to be history oriented.”46Without necessarily rejecting MacArthur's explanation, my study suggests a more complex relationship between taxonomic and ecological plant geographies. At the turn of the century a group of botanists self-consciously defined a new area of botanical research. These ecologists defined their new discipline in opposition to what they believed was a moribund, nineteenth-century, natural-history tradition. They turned from historically oriented, descriptive, taxonomic plant geography to experimental physiology. The new ecological plant geography was to focus on communities rather than on species, on proximate environmental causes rather than on historical explanations, and on physiological experiments rather than on morphological descriptions.As we look back, much of the “revolt from morphology” was rhetorical. Ecologists never completely replaced species as units of distribution, nor did they set geography on an explicitly physiological basis. Indeed, much of early ecological research was, quite simply, descriptive. Plant communities were defined in terms of dominant species, representative life forms, or general physiognomy. The underlying physiological basis for community characteristics was more often assumed than demonstrated by experiments.Despite the fact that ecological plant geography was not a truly physiological specialty, it was significantly different from more traditional taxonomic plant geography. First, ecologists were less explicitly evolutionary in their approach than were taxonomists. Following Darwin, most taxonomic plant geographers viewed distribution in historical terms. In contrast, early ecologists tended to ignore the traditional geographic problems. Most ecologists were skeptical of historical explanations, emphasizing instead the proximate, environmental causes of distribution. While some nineteenth-century biogeographers had studied the correlation between climate and vegetation, twentieth-century ecologists focused much more sharply on the interactions between plant and environment. Plant ecologists did not place biogeography on a physiological basis, but by emphasizing physiology they laid the foundation for a more detailed understanding of adaption. This emphasis on physiology and environmental causation was a second distinguishing characteristic of ecological plant geography. Finally, the idea of the plant community, articulated by Eugenius Warming in 1895, provided ecologists with a unique perspective on the distribution of plants. For early ecologists, the community was more than an assemblage of species; it was an integrated unit. The distribution of these units became the major focus of ecological plant geography. Communities never completely replaced species as geographic units, and the distinction between flora and vegetation was often blurred. Nonetheless, ecologists were innovative in studying the distribution of structurally and functionally integrated groups of plants.In the twentieth century plant geography has occupied an anomalous position in biology. It has not developed into an autonomous discipline, nor has it been incorporated into the developing discipline of ecology. Ecologists and taxonomists have pursued fairly distinct styles of geographic research, with the result that two relatively independent approaches to the study of plant distribution have persisted.

The transition from the traditional to the representational theory of measurement around the turn of the century was accompanied by little sustained criticism of the former. The most forceful critique was Bertrand Russell''s 1897 Mind paper, On the relations of number and quantity. The traditional theory has it that real numbers unfold from the concept of continuous quantity. Russell''s critique identified two serious problems for this theory: (1) can magnitudes of a continuous quantity be defined without infinite regress; and (2) (...) can additive relations between such magnitudes exist if magnitudes are not divisible? The present paper shows how the traditional theory answers these questions and compares the traditional and representational theories as contributions to our understanding of the logic of application.
