Technological development plays a critical role in society’s ability to address environmental issues. Building on Teece’s profiting from innovation framework, we articulate how a double-externality problem weakens the appropriability regime surrounding pollution reduction technology (PRT). We then develop a theoretical framework articulating how weak appropriability induces firms to modify their innovation strategies for PRT development by increasing the extent to which they engage in organizational exploration (rather than exploitation) and emphasizing incremental (rather than radical) technologies. Noting that the effects of (...) weak appropriability are unlikely to be static, we detail how the accumulation of organizational capabilities for reducing pollution diminishes the extent to which firms modify their innovation strategies for PRT. That is, firms become less exploratory and less focused on incremental technology as they gain experience with pollution reduction. Results of broad-sample empirical analyses of 206,277 patents held by 203 U.S. manufacturing firms over a 20-year period provide support for our framework. (shrink)

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.

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.

We provide self-contained proof of a theorem relating probabilistic coherence of forecasts to their non-domination by rival forecasts with respect to any proper scoring rule. The theorem recapitulates insights achieved by other investigators, and clarifi es the connection of coherence and proper scoring rules to Bregman divergence.

"This foundational text was one of the first books to integrate work from moral philosophy, developmental/moral psychology, applied psychology, political and social economy, and political science, as well as business scholarship. The third edition utilizes ideas from the first two to provide readers with a practical model for ethical decision making and includes examples from I-O research and practice, as well as current business events"--.

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 two contrasting theoretical approaches to visual perception, the constructivist and the ecological, are briefly presented and illustrated through their analyses of space and size perception. Earlier calls for their reconciliation and unification are reviewed. Neurophysiological, neuropsychological, and psychophysical evidence for the existence of two quite distinct visual systems, the ventral and the dorsal, is presented. These two perceptual systems differ in their functions; the ventral system's central function is that of identification, while the dorsal system is mainly engaged in (...) the visual control of motor behavior. The strong parallels between the ecological approach and the functioning of the dorsal system, and between the constructivist approach and the functioning of the ventral system are noted. It is also shown that the experimental paradigms used by the proponents of these two approaches match the functions of the respective visual systems. A dual-process approach to visual perception emerges from this analysis, with the ecological-dorsal process transpiring mainly without conscious awareness, while the constructivist-ventral process is normally conscious. Some implications of this dual-process approach to visual-perceptual phenomena are presented, with emphasis on space perception. Key Words: constructivist; dual-process approach; ecological; size perception; space perception; two visual systems; visual perception theories. (shrink)

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)

One can have no prior credence whatsoever (not even zero) in a temporally indexical claim. This fact saves the principle of conditionalization from potential counterexample and undermines the Elga and Arntzenius/Dorr arguments for the thirder position and Lewis' argument for the halfer position on the Sleeping Beauty Problem, thereby supporting the double-halfer position. -/- .

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)

Virtue ethicists argue that modern ethical theories aim to give direct guidance about particular situations at the cost of offering artificial or narrow accounts of ethics. In contrast, virtue ethical theories guide action indirectly by helping one understand the virtues—but the theory will not provide answers as to what to do in particular instances. Recently, this had led many to think that virtue ethical theories are self-effacing the way some claim consequentialist and deontological theories are. In this paper I defend (...) virtue ethics against the charge of self-effacement. I distinguish between modestly self-effacing theories, immodestly self-effacing theories and theories that recommend indirect guidance. Though all self-effacing theories are indirect, not all indirect theories are self-effacing. I argue that virtue ethics is not self-effacing, but rather indirectly action-guiding. The response I articulate draws on the distinctive virtue ethical mode of action-guidance: namely, that thinking hard about virtue and what kind of person one aims to be offers the kind of guidance we want (or should want) as we face practical moral problems.

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.

A common view is that species occupy a unique position on the Tree of Life. Evaluating this claim requires an understanding of what the Tree of Life represents. The Tree represents history, but there are at least three biological levels that are often said to have genealogies: species, organisms, and genes. Here I focus on defending the plausibility of a gene-based account of the Tree. This leads to an account of species that are determined by gene genealogies. On this view, (...) an exclusive group is a group of organisms that forms a clade for a higher proportion of the genome than any conflicting clade. Taxa occupy a unique position in what can be called the ‘primary concordance tree’. But each gene has its own historical ‘Tree of Life’. I conclude by arguing that both organismal pedigrees with their corresponding Tree as well as gene genealogies and their trees are objectively real and play important, but different, roles in biological practice.

Kant's introduction of a distinctive form of philosophical investigation and proof, known as transcendental, inaugurated a new philosophical tradition. Transcendental Philosophy and Naturalism assesses the present state and contemporary relevance of this tradition. The contributors aim to understand the theoretical structures involved in transcendental explanation, and to assess the contemporary relevance of the transcendental orientation, in particular with respect to contemporary philosophical naturalism. These issues are approached from both naturalistic and transcendental perspectives.

Terence Horgan defends the thirder position on the Sleeping Beauty problem, claiming that Beauty can, upon awakening during the experiment, engage in “synchronic Bayesian updating” on her knowledge that she is awake now in order to justify a 1/3 credence in heads. In a previous paper, I objected that epistemic probabilities are equivalent to rational degrees of belief given a possible epistemic situation and so the probability of Beauty’s indexical knowledge that she is awake now is necessarily 1, precluding such (...) updating. In response, Horgan maintains that the probability claims in his argument are to be taken, not as claims about possible rational degrees of belief, but rather as claims about “quantitative degrees of evidential support.” This paper argues that the most plausible account of quantitative degree of support, when conjoined with any of the three major accounts of indexical thought in such a way as to plausibly constrain rational credence, contradicts essential elements of Horgan’s argument.

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.

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.

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)

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.

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)
