The belief that syntax is an innate, autonomous, species-specific module is highly questionable. Syntax demonstrates the mosaic nature of evolutionary change, in that it made use of (and led to the enhancement of) numerous preexisting neurocognitive features. It is best understood as an emergent characteristic of the explosion of semantic complexity that occurred during hominid evolution.

In this paper, we argue that there are patterns of innovation occurring in less economically developed countries (LEDCs) that have been historically overlooked by the innovation studies literature, including the literature on innovation systems and the triple helix. This paper briefly surveys cases in agriculture, banking, biomedicine and information and communications technologies that demonstrate organizational, scientific and technological innovation in Africa, South Asia, and Brazil. In particular, we track new developments in two distinctive patterns within LEDCs: (1) civil society as (...) a site of innovation and; (2) innovation through appropriation. By systematically uncovering patterns of innovation in LEDCs, science and technology policy scholars may make new theoretical gains in innovation studies that can potentially contribute to innovation policies in the global South.

This book is a collection of secondary essays on America's most important philosophic thinkers—statesmen, judges, writers, educators, and activists—from the colonial period to the present. Each essay is a comprehensive introduction to the thought of a noted American on the fundamental meaning of the American regime.

The translational research community, in general, and the Clinical and Translational Science Awards (CTSA) community, in particular, share the vision of repurposing EHRs for research that will improve the quality of clinical practice. Many members of these communities are also aware that electronic health records (EHRs) suffer limitations of data becoming poorly structured, biased, and unusable out of original context. This creates obstacles to the continuity of care, utility, quality improvement, and translational research. Analogous limitations to sharing objective data in (...) other areas of the natural sciences have been successfully overcome by developing and using common ontologies. This White Paper presents the authors’ rationale for the use of ontologies with computable semantics for the improvement of clinical data quality and EHR usability formulated for researchers with a stake in clinical and translational science and who are advocates for the use of information technology in medicine but at the same time are concerned by current major shortfalls. This White Paper outlines pitfalls, opportunities, and solutions and recommends increased investment in research and development of ontologies with computable semantics for a new generation of EHRs.

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.

Condillac's Essay on the Origin of Human Knowledge, first published in French in 1746 and offered here in a new translation, represented in its time a radical departure from the dominant conception of the mind as a reservoir of innately given ideas. Descartes had held that knowledge must rest on ideas; Condillac turned this upside down by arguing that speech and words are the origin of mental life and knowledge. His work influenced many later philosophers, and also anticipated Wittgenstein's view (...) of language and its relation to mind and thought. (shrink)

Famously, Aristotle in his discussion of friendship in Books 8 and 9 of the Nicomachaean Ethics (EN) introduces a tripartite distinction in friendship. Friendships are either friendships of pleasure or of utility or of character. This typology has struck a responsive chord among many other writers on friendship. Nevertheless it is our contention that there is a fourth important category of friendship that has been overlooked in the philosophical literature. We call this fourth category, asymmetrical friendship. Asymmetrical friendships do not (...) fit the Aristotelian tripartite classification in that they are not friendships of pleasure or of utility nor are they recognizably what Aristotle means by character friendship even though they may hold much in common in various ways with character friendship. We will have little to say about friendships of pleasure or utility. Instead we will elucidate our fourth category of asymmetrical friendships in contradistinction to Aristotle’s notion of character friendships. Aristotle thinks that character friendships are neither friendships of pleasure nor utility but instead are ones in which the friends care for each other for their own sakes. We show that the tradition of Aristotelian thinking requires character friendship to be symmetrical in various ways that we will explain soon. In contrast we argue that asymmetrical friendships are also not friendships of pleasure or utility but like character friendships are ones in which the friends care for each other for their own sakes. Such friendships appear especially valuable to us in the phenomenology of our lives. Thus they are unlike friendships of pleasure or utility that may also be asymmetrical in various ways. And they are therefore also unlike Aristotle’s symmetrical and certainly valuable character friendships that seldom appear at all in our imperfect lives lived as they are in an imperfect world.

A.P. Martinich's interpretation that in Leviathan Thomas Hobbes believed that the laws of nature are the commands of God and that he did not rely on the Bible to prove this has been criticized by Greg Forster in this journal (2003). Forster uses these criticisms to develop his own view that Hobbes was insincere when he professed religious beliefs. We argue that Forster misrepresents Martinich's view, is mistaken about what evidence is relevant to interpreting whether Hobbes was sincere or (...) not, and is mistaken about some of Hobbes's central doctrines. Forster's criticisms are worth discussing at length for at least three reasons. He takes the debate about Hobbes's sincerity to a new level of sophistication; his misinterpretations of Hobbes may become accepted as correct; and his criticisms raise issues about the proper method of interpreting historical texts.

Quine often argued for a simple, untyped system of logic rather than the typed systems that were championed by Russell and Carnap, among others. He claimed that nothing important would be lost by eliminating sorts, and the result would be additional simplicity and elegance. In support of this claim, Quine conjectured that every many-sorted theory is equivalent to a single-sorted theory. We make this conjecture precise, and prove that it is true, at least according to one reasonable notion of theoretical (...) equivalence. Our clarification of Quine’s conjecture, however, exposes the shortcomings of his argument against many-sorted logic. (shrink)

Wilhelm (Forthcom Synth 199:6357–6369, 2021) has recently defended a criterion for comparing structure of mathematical objects, which he calls Subgroup. He argues that Subgroup is better than SYM \(^*\), another widely adopted criterion. We argue that this is mistaken; Subgroup is strictly worse than SYM \(^*\). We then formulate a new criterion that improves on both SYM \(^*\) and Subgroup, answering Wilhelm’s criticisms of SYM \(^*\) along the way. We conclude by arguing that no criterion that looks only to the (...) automorphisms of mathematical objects to compare their structure can be fully satisfactory. (shrink)

Mathematicians, physicists, and philosophers of physics often look to the symmetries of an object for insight into the structure and constitution of the object. My aim in this paper is to explain why this practice is successful. In order to do so, I present a collection of results that are closely related to (and in a sense, generalizations of) Beth’s and Svenonius’ theorems.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

In his book Philosophy of Logic, Putnam (1971) presents a short argument which reads like—and indeed, can be reconstructed as—a formal proof that a nominalistic physics is impossible. The aim of this paper is to examine Putnam’s proof and show that it is not compelling. The precise way in which the proof fails yields insight into the relation that a nominalistic physics should bear to standard physics and into Putnam’s indispensability argument.

Corruption devours profits, people, and the planet. Ethical leaders promote ethical behaviors. We develop a first-stage moderated mediation theoretical model, explore the intricate relationships between ethical leadership and employee ethical behaviors, and treat ethical climate and organizational justice as dual mediators and leaders’ moral attentiveness as a moderator. We investigate leadership from two perspectives—leaders’ self-evaluation of moral attentiveness and members’ perceptions of ethical leadership. We theorize: These dual mediation mechanisms are more robust for high moral leaders than low moral leaders. (...) Our three-wave data collected from multiple sources, 236 members and 98 immediate supervisors in the Republic of Iraq, support our theory. Specifically, ethical leadership robustly impacts organizational justice’s intensity and magnitude, leading to high employee ethical behaviors when leaders’ moral attentiveness is high than low. However, ethical leadership only influences the ethical climate’s intensity but has no impact on the magnitude when leaders’ moral attentiveness is high than low. Therefore, organizational justice is a more robust mediator than the ethical climate in the omnibus context of leader moral attentiveness. Our findings support Western theory and constructs, demonstrating a new theory for Muslims in Arabic’s emerging markets. Individual decision-makers apply their values as a lens to frame their concerns in the immediate and omnibus contexts to maximize their expected utility and ultimate serenity-happiness. Ethical leadership trickles down to employee ethical behaviors, providing practical implications for improving the ethical environment, corporate social responsibility, leader-member exchange, business ethics, and economic potentials in the global competitive markets.

The destruction of cultural heritage in war is currently attracting considerable attention. ISIS’s campaign of deliberate destruction across the Middle East was met with widespread horror and calls for some kind of international response. The United States attracted criticism for both its accidental damaging of Ancient Babylon in 2015 and its failure to protect the Mosul Museum from looters in 2003. In 2016, the International Criminal Court prosecuted its first case of the destruction of heritage as a war crime. While (...) the destruction of heritage is widely condemned, there has also been condemnation of calls to mobilize our resources for the sake of heritage protection when human beings face threats to life and limb. Such issues are both philosophically rich and personally significant to a wide range of people. And yet they have been largely neglected by academic philosophers. This book makes a substantial contribution to developing this new philosophical territory. The contributors are a mixture of internationally recognized authorities in their fields and early-career researchers working in this area. Their eleven original essays investigate a variety of philosophical and ethical issues arising from the phenomenon of heritage destruction in war, including conflicts between protecting heritage and protecting people, how we ought to respond to heritage that is damaged in war, the nature of the harm caused by such damage, and the morally appropriate treatment of sites of war and conflict that have themselves become heritage sites.

Husserl’s early picture of explanation in the sciences has never been completely provided. This lack represents an oversight, which we here redress. In contrast to currently accepted interpretations, we demonstrate that Husserl does not adhere to the much maligned deductive-nomological (DN) model of scientific explanation. Instead, via a close reading of early Husserlian texts, we reveal that he presents a unificationist account of scientific explanation. By doing so, we disclose that Husserl’s philosophy of scientific explanation is no mere anachronism. It (...) is, instead, tenable and relevant. We discuss how Husserl and other contemporary thinkers draw theoretical inspiration from the same source—namely, Bernard Bolzano. Husserl’s theory of scientific explanation shares a common language and discusses the same themes as, for example, Phillip Kitcher and Kit Fine. To advance our novel reading, we discuss Husserl’s investigations of grounding, inter-lawful explanation, intra-mathematical explanation, and scientific unification. (shrink)

This is an essay review of Jill North’s book Physics, Structure, and Reality. It focuses on two of the main topics of the book. The first is North’s idea that we can use coordinates as a window into the structure that a theory posits; the second is North’s argument for the inequivalence of Lagrangian and Newtonian mechanics.

The rubric “The Late Derrida,” with all puns and ambiguities cheerfully intended, points to the late work of Jacques Derrida, the vast outpouring of new writing by and about him in the period roughly from 1994 to 2004. In this period Derrida published more than he had produced during his entire career up to that point. At the same time, this volume deconstructs the whole question of lateness and the usefulness of periodization. It calls into question the “fact” of his (...) turn to politics, law, and ethics and highlights continuities throughout his oeuvre. The scholars included here write of their understandings of Derrida’s newest work and how it impacts their earlier understandings of such classic texts as Glas and Of Grammatology . Some have been closely associated with Derrida since the beginning—both in France and in the United States—but none are Derrideans. That is, this volume is a work of critique and a deep and continued engagement with the thought of one of the most significant philosophers of our time. It represents a recognition that Derrida’s work has yet to be addressed—and perhaps can never be addressed—in its totality. (shrink)

The Philosophy of Rhetoric is widely regarded as the most important work of a theory of rhetoric produced in the 18th century. Campbell's work engages such themes in an attempt to formulate a universal theory of human communication. Campbell attempts to develop his theory by discovering deep principles in human nature that account for all instances and kinds of human communication. He seeks to derive all communication principles and processes empirically. In addition, all statements in discourse that have to do (...) with matters of fact and human affairs are likewise to be empirically derived. Thus, his theory of rhetoric is vastly wider than, and different from, such classical theories as those proposed by Aristotle, Cicero, and Quintilian, whose theories focused on discourse related to civic affairs. By attempting to elaborate a general theory of rhetoric through empirical procedures, Campbell's project reveals the limitations of his method. He cannot ground all statements empirically and it is at this point that his theological position comes into play. Inspection of his religious views shows that God's design of human nature, and God's revelations to humankind, make moral and spiritual truths known and quite secure to human beings, although not empirically.

This volume contains thirteen papers that were presented at the 2017 Annual Meeting of the Canadian Society for History and Philosophy of Mathematics/Société canadienne d’histoire et de philosophie des mathématiques, which was held at Ryerson University in Toronto. It showcases rigorously reviewed modern scholarship on an interesting variety of topics in the history and philosophy of mathematics from Ancient Greece to the twentieth century. A series of chapters all set in the eighteenth century consider topics such as John Marsh’s techniques (...) for the computation of decimal fractions, Euler’s efforts to compute the surface area of scalene cones, a little-known work by John Playfair on the practical aspects of mathematics, and Monge’s use of descriptive geometry. After a brief stop in the nineteenth century to consider the culture of research mathematics in 1860s Prussia, the book moves into the twentieth century with an examination of the historical context within which the Axiom of Choice was developed and a paper discussing Anatoly Vlasov’s adaptation of the Boltzmann equation to ionized gases. The remaining chapters deal with the philosophy of twentieth-century mathematics through topics such as an historically informed discussion of finitism and its limits; a reexamination of Mary Leng’s defenses of mathematical fictionalism through an alternative, anti-realist approach to mathematics; and a look at the reasons that mathematicians select specific problems to pursue. Written by leading scholars in the field, these papers are accessible to not only mathematicians and students of the history and philosophy of mathematics, but also anyone with a general interest in mathematics.

The great medieval philosopher Thomas Aquinas was Dominican regent master in theology at the University of Paris, where he presided over a series of questions - academic debates - on ethical topics. This volume offers translations of disputed questions on the nature of virtues in general, the fundamental or 'cardinal' virtues of practical wisdom, justice, courage, and temperateness, the divinely bestowed virtues of hope and charity, and the practical question of how, when and why one should rebuke a 'brother' (...) for wrongdoing. The introduction explains how Aquinas's theory of virtue fits into his ethics as a whole, and it illuminates Aquinas's views by explaining the institutional and intellectual context in which these disputed questions were debated.

What determines whether an action is right or wrong? Morality, Rules, and Consequences: A Critical Reader explores for students and researchers the relationship between consequentialist theory and moral rules. Most of the chapters focus on rule consequentialism or on the distinction between act and rule versions of consequentialism. Contributors, among them the leading philosophers in the discipline, suggest ways of assessing whether rule consequentialism could be a satisfactory moral theory. These essays, all of which are previously unpublished, provide students in (...) moral philosophy with essential material and ask key questions on just what the criteria for an adequate moral theory might be.

In these three dialogues, renowned for their dialectical structure and linguistic precision, Anselm sets out his classic account of the relationship between freedom and sin--its linchpin his definition of freedom of choice as the power to preserve rectitude of will for its own sake. In doing so, Anselm explores the fascinating implications for God, human beings, and angels of his conclusion that freedom of choice neither is nor entails the power to sin. In addition to an Introduction, notes, and a (...) glossary, Thomas Williams brings to the translation of these important dialogues the same precision and clarity that distinguish his previous translation of Anselm's _Proslogion_ and _Monologion_, which Professor Paul Spade of Indiana University called "scrupulously faithful and accurate without being slavishly literal, yet lively and graceful to both the eye and ear.

We treat science as a Hayekian social order whose distinctive emergent characteristic is the generation of knowledge. We model modern science as an institutional form that principally relies on publication with citation and its effects on individual reputation in order to study the possible effects of funding on science. We develop a taxonomy of three broad categories of effect: those having to do with the direction followed by scientific activity, those involving the operational and financial stability of both the physical (...) institutions integral to scientific work and the scientists themselves, and those due to distortions of the basic knowledge-generating procedures of science. It is argued that, while directional effects of funding are ubiquitous, destabilizing and distorting effects are much more likely to emerge when funding sources are concentrated than when they are decentralized. Further, when funding is accompanied by regulatory oversight, the possibilities for distortion are significantly increased. Examples of such effects actually occurring under the current U.S. funding regime are discussed. (shrink)

In this paper we offer a reconstruction of Anselm’s account of freedom that resolves various apparent inconsistencies. The linchpin of this account is the definition of freedom. Anselm argues that the power to preserve rectitude for its own sake requires the power to initiate an action of which the agent is the ultimate cause, but it does not always require that alternative possibilities be available to the agent. So while freedom is incompatible with coercion and external causal determination, an agent (...) can, under certain circumstances, act freely even though he cannot act otherwise than he does. (shrink)

According to Anselm's official definition, freedom of choice is ‘the power to preserve rectitude of will for the sake of that rectitude itself.’ From the point of view of contemporary metaphysics, this is one of the most unhelpful definitions imaginable. Does such freedom require alternative possibilities, for example? Is it compatible with causal determination? Is the exercise of such freedom a necessary and sufficient condition for moral responsibility? The definition sheds no light on these questions.And so we need to move (...) on from Anselm's definition to Anselm's account of freedom. Here, though, we encounter the opposite problem. Where Anselm's definition seems not to answer these questions at all, Anselm's account seems to answer all these questions, sometimes with a yes and sometimes with a no. Consider the question about alternative possibilities. In De libertate arbitrii, Anselm seems clearly to deny that freedom involves alternative possibilities. God, the good angels, and the blessed dead cannot do otherwise than preserve rectitude, but they are still free- freer, in fact, than those who are capable of abandoning rectitude. (shrink)

Ranging from his early treatises, the ’Monologion’ (a work written to show his monks how to meditate on the divine essence) and the ’Proslogion’ (best known for its advancement of the so-called ontological argument for the existence of God), to his three philosophical dialogues on metaphysical topics such as the relationship between freedom and sin, and late treatises on the Incarnation and salvation, this collection of Anselm’s essential writings will be of interest to students of the history of philosophy and (...) theology as well as to anyone interested in examining what Anselm calls "the reason of faith."

We extend the relational algebra of Chin and Tarski so that it is multisorted or, as we prefer, typed. Each type supports a local Boolean algebra outfitted with a converse operator. From Lyndon, we know that relation algebras cannot be represented as proper relation algebras where a proper relation algebra has binary relations as elements and the algebra is singly-typed. Here, the intensional conjunction, which was to represent relational composition in Chin and Tarski, spans three different local algebras, thus the (...) term distributed in the title. Since we do not rely on proper relation algebras, we are free to re-express the algebras as typed. In doing so, we allow many different intensional conjunction operators. We construct a typed logic over these algebras, also known as heterogeneous algebras of Birkhoff and Lipson. The logic can be seen as a form of relevance logic with a classical negation connective where the Routley-Meyer star operator is reified as a converse connective in the logic. Relevance logic itself is not typed but our work shows how it can be made so. Some of the properties of classical relevance logic are weakened from Routley-Meyer’s version which is too strong for a logic over relation algebras. (shrink)

Scotus is notorious for occasionally making statements that, on their face at least, smack of voluntarism, but there has been a lively debate about whether Scotus is really a voluntarist after all. Now the debate is not over whether Scotus lays great emphasis on the role of the divine will with respect to the moral law. No one could sensibly deny that he does, and if such an emphasis constitutes voluntarism, then no one could sensibly deny that Scotus is a (...) voluntarist. As I am using the word, however, voluntarism is the view that (i) the goodness of almost all things, as well as the rightness of almost all acts, depends wholly on the divine will and (ii) what God wills with respect to those things and those acts is not in turn to be explained by reference to the divine intellect, human nature, or anything else. This is the view that Scotus’s critics decry and his defenders disclaim. Thus, his critics have seized on these passages and accused Scotus of believing that the moral law depends simply on “the arbitrary will of God.” His most sympathetic interpreters, however, have devoted great ingenuity to showing that Scotus did not mean anything unpalatable by these statements.1 What the critics and defenders apparently have in common is the view that voluntarism is an implausible and even discreditable doctrine. Interpreters who read Scotus as a voluntarist intend thereby to damn his moral views; interpreters sympathetic to his moral views feel compelled to mitigate his voluntarism. I wish to argue for a different approach. I agree with his defenders that Scotus’s moral philosophy ought to be taken seriously. But I think the best way to take any philosopher’s view seriously is to let him speak for himself, not to decide in advance that he must not have held a view that we find implausible. Let me suggest an analogy that will make my position clearer. Very nearly everyone finds immaterialism implausible. (shrink)

This paper considers Aquinas's accounts of the end of human action and the structure of human action, examines the debate between intellectualist and voluntarist interpretations of Aquinas, and corrects mistaken accounts of Aquinas's views on freedom, necessitation, and causation.
