Volterra's (1926) equations for competition and predator-prey interactions are modified by introduction of root terms. A critical comparison with the original equations shows that the dynamic properties of the systems remain essentially alike, while the modification allows for explicit solution of the differential equations. Detailed solutions and numerical examples are given.

The Hyperuniverse Program is a new approach to set-theoretic truth which is based on justifiable principles and leads to the resolution of many questions independent from ZFC. The purpose of this paper is to present this program, to illustrate its mathematical content and implications, and to discuss its philosophical assumptions.

What counts as an intuitively plausible set theoretic content (notion, axiom or theorem) has been a matter of much debate in contemporary philosophy of mathematics. In this paper I develop a critical appraisal of the issue. I analyze first R. B. Jensen's positions on the epistemic status of the axiom of constructibility. I then formulate and discuss a view of intuitiveness in set theory that assumes it to hinge basically on mathematical success. At the same time, I present accounts of (...) set theoretic axioms and theorems formulated in non-strictly mathematical terms, e.g., by appealing to the iterative concept of set and/or to overall methodological principles, like unify and maximize, and investigate the relation of the latter to success in mathematics.

This short essay is an introduction to Emmanuele Morandi streams of research, which aimed at recreating a new connection between social sciences and metaphysics, empirical research and moral reflections. After a brief introduction, the kind of anthropological critical metaphysical realism fostered by Morandi is outlined. The third paragraph addresses some foundational aspect of his social ontology; lastly, the complex distinction between social, political and economic spheres will be presented.

Writing from a scientifically and philosophically informed perspective, the authors provide a critical overview of the conceptual difficulties encountered in many current neuroscientific and psychological theories.

A long-standing theme in discussion of perception and thought has been that our primary cognitive contact with individual objects and events in the world derives from our perceptual contact with them. When I look at a duck in front of me, I am not merely presented with the fact that there is at least one duck in the area, rather I seem to be presented withthisthing (as one might put it from my perspective) in front of me, which looks to (...) me to be a duck. Furthermore, such a perception would seem to put me in a position not merely to make the existential judgment that there is some duck or other present, but rather to make a singular, demonstrative judgment, that that is a duck. My grounds for an existential judgment in this case derives from my apprehension of the demonstrative thought and not vice versa. (shrink)

This book defends antitheodicism, arguing that theodicies, seeking to excuse God for evil and suffering in the world, fail to ethically acknowledge the victims of suffering. The authors argue for this view using literary and philosophical resources, commencing with Immanuel Kant's 1791 "Theodicy Essay" and its reading of the Book of Job. Three important twentieth century antitheodicist positions are explored, including "Jewish" post-Holocaust ethical antitheodicism, Wittgensteinian antitheodicism exemplified by D.Z. Phillips and pragmatist antitheodicism defended by William James. The authors argue (...) that these approaches to evil and suffering are fundamentally Kantian. Literary works such as Franz Kafka'sThe Trial, Samuel Beckett's Waiting for Godot, and George Orwell's Nineteen Eighty-Four, are examined in order to crucially advance the philosophical case for antitheodicism.

Temporal Logic: From Ancient Ideas to Artificial Intelligence deals with the history of temporal logic as well as the crucial systematic questions within the field. The book studies the rich contributions from ancient and medieval philosophy up to the downfall of temporal logic in the Renaissance. The modern rediscovery of the subject, which is especially due to the work of A. N. Prior, is described, leading into a thorough discussion of the use of temporal logic in computer science and the (...) understanding of natural language. Temporal Logic: From Ancient Ideas to Artificial Intelligence thus interweaves linguistic, philosophical and computational aspects into an informative and inspiring whole. (shrink)

In his last book, David Armstrong sets out his metaphysical system in a set of concise and lively chapters each dealing with one aspect of the world. He begins with the assumption that all that exists is the physical world of space-time. On this foundation he constructs a coherent metaphysical scheme that gives plausible answers to many of the great problems of metaphysics. He gives accounts of properties, relations, and particulars; laws of nature; modality; abstract objects such as numbers; and (...) time and mind. (shrink)

Is consciousness a purely physical phenomenon? Most contemporary philosophers and theorists hold that it is, and take this to be supported by modern science. But a significant minority endorse non-physicalist theories such as dualism, idealism and panpsychism, among other reasons because it may seem impossible to fully explain consciousness, or capture what it's like to be in conscious states (such as seeing red, or being in pain), in physical terms. This Element will introduce the main non-physicalist theories of consciousness and (...) explain the most important arguments for them, and consider how they each respond to the scientific and other arguments in support of physicalism. This title is also available as Open Access on Cambridge Core. (shrink)

Western democracy is now at a critical juncture. Some worry that power has been wrested from the people and placed in the hands of a small political elite. Others argue that the democratic system gives too much power to a populace that is largely ill-informed and easily swayed by demagogues. This classic study of democratic principles is thus now more relevant than ever. A renowned historian of antiquity and political philosophy, Sir M.I. Finley offers a comparative analysis of Greek and (...) modern conceptions of democracy. As he puts the ancient Greeks in dialogue with their contemporary counterparts, Finley tackles some of the most pressing issues of our day, including public apathy, partisanship, consensus politics, distrust of professional politicians, and the limits of free speech. Including three lectures that Finley delivered at Rutgers University, plus two additional essays that further illuminate his thinking, _Democracy Ancient and Modern _explores the dramatic differences between the close-knit civil society of the ancient Greeks and our own atomized mass societies. By mapping out democracy’s past and its present manifestations, this book helps us plot a course for democracy’s future. (shrink)

The ideal introduction for students of semantics, Lexical Meaning fills the gap left by more general semantics textbooks, providing the teacher and the student with insights into word meaning beyond the traditional overviews of lexical relations. The book explores the relationship between word meanings and syntax and semantics more generally. It provides a balanced overview of the main theoretical approaches, along with a lucid explanation of their relative strengths and weaknesses. After covering the main topics in lexical meaning, such as (...) polysemy and sense relations, the textbook surveys the types of meanings represented by different word classes. It explains abstract concepts in clear language, using a wide range of examples, and includes linguistic puzzles in each chapter to encourage the student to practise using the concepts. 'Adopt-a-Word' exercises give students the chance to research a particular word, building a portfolio of specialist work on a single word. (shrink)

The concept of the receptive field, first articulated by Hartline, is central to visual neuroscience. The receptive field of a neuron encompasses the spatial and temporal properties of stimuli that activate the neuron, and, as Hubel and Wiesel conceived of it, a neuron’s receptive field is static. This makes it possible to build models of neural circuits and to build up more complex receptive fields out of simpler ones. Recent work in visual neurophysiology is providing evidence that the classical receptive (...) field is an inaccurate picture. The receptive field seems to be a dynamic feature of the neuron. In particular, the receptive field of neurons in V1 seems to be dependent on the properties of the stimulus. In this paper, we review the history of the concept of the receptive field and the problematic data. We then consider a number of possible theoretical responses to these data. (shrink)

This book presents a collection of essays on institutional theory written by the German sociologist and Weber-expert M. Rainer Lepsius. Based on Weber's work, the author develops concepts of institutional theory, which he subsequently applies to topics such as National Socialism, democratization processes, German unification, and the institutionalization of the European Union. By showing how charismatic leadership can under certain circumstances threaten democratic structures and curtail individual freedoms, and by analyzing the structural and cultural conditions under which people develop trust (...) in political and social structures and ultimately come to support and comply with them, the author provides a sound analytical understanding of the development of democratic institutions and a democratic political culture. This collection of essays was edited, translated and commented on by Claus Wendt. (shrink)

The phenomenal powers view claims that phenomenal properties metaphysically necessitate their effects in virtue of how they feel, and thereby constitute non-Humean causal powers. For example, pain necessitates that subjects who experience it try to avoid it in virtue of feeling bad. I argue for this view based on the inconceivability of certain phenomenal properties necessitating different effects than their actual ones, their ability to predict their effects without induction, and their ability to explain their effects without appeal to laws (...) or regularities. I also offer a harmony argument according to which the view offers the best explanation for otherwise seemingly fortunate psychophysical regularities. I then outline the view’s main implications for the metaphysics of causation and philosophy of mind. (shrink)

Early in his Essays on Intellectual Powers, Reid draws a distinction between mental power, mental operation, and mental capacity (EIP 21). To the untrained eye, these terms could probably be used interchangeably, and Reid believes this is correct, up to a point. He argues that, if we are interested in understanding exactly how the human mind works, we must use these terms with more precise meanings. This is part of his more general strategy of trying to always use the words (...) with their common meanings, as much as possible, but also pointing out that certain philosophical distinctions are needed to carry out the project of laying out the foundations of the science of the mind. This paper explains what the distinction between power, operation, and capacity is, according to Reid, with the goal of understanding why it is important to draw such a distinction, not only for the Reidian project, but for action theory, more generally.

The given is the state of a mind in its primary engagement with the world. A satisfactory epistemology—one, it turns out, that is foundationalist and includes a naïve realist view of perception—requires a certain account of the given. Moreover, knowledge based on the given requires both a particular view of the world itself and a heterodox account of judgment. These admittedly controversial claims are supported by basic ontological considerations. I begin, then, with two contradictory views of the world per se (...) and the structure one experiences. I draw out the consequences of these two views for what intentionality is. The two views yield incompatible accounts of the given. The definitive spontaneity of the one account, and passivity of the other, can be understood in terms of the structure (or lack thereof) in the given. In defense of the claim that a structured given is not an apt epistemic basis, I examine an attempt to found an epistemology on such an account in light of the so-called myth of the given. I maintain that the given, if it is to provide some justification for taking the world to be a particular way, must be unstructured. To support this, I first discuss a significant problem with traditional foundationalism. I then argue that a satisfactory (foundationalist) epistemology requires the rejection of the orthodox propositional view of judgment in favor of a non-propositional, reistic view. (shrink)

For over two centuries, Western scholars have discussed African philosophy and culture, often in disparaging, condescending terms, and always from an alien European perspective. Many Africans now share this perspective, having been trained in the western, empirical tradition. Makinde argues that, particularly in view of the costs and failings of western style culture, Africans must now mold their own modern culture by blending useful western practices with valuable indigenous African elements. Specifically, Makinde demonstrates the potential for the development of African (...) philosophy and even African traditional medicine. Following the lead of a number of countries with government policies of incorporating indigenous medicine with orthodox Western medicine, Makinde argues that traditional African practices should be taken seriously, both medically and scientifically. Further, he charges African scholars with the responsibility of investigating these and other elements of traditional African culture in order to dispel their mystery and secrecy through modern research and useful publications.

Philosophical Thought in Russia in the Second Half of the 20th Century is the first book of its kind that offers a systematic overview of an often misrepresented period in Russia's philosophy. Focusing on philosophical ideas produced during the late 1950s – early 1990s, it reconstructs the development of genuine philosophical thought in the Soviet period and introduces those non-dogmatic Russian thinkers who saw in philosophy a means of reforming social and intellectual life. Covering such areas of philosophical inquiry as (...) philosophy of science, philosophical anthropology, the history of philosophy, activity approach as well as communication and dialogue studies, the volume presents and thoroughly discusses central topics and concepts developed by Soviet thinkers in that particular fields. Written by a team of internationally recognized scholars from Russia and abroad, it examines the work of well-known Soviet philosophers (such as Mikhail Bakhtin, Evald Ilyenkov and Merab Mamardashvili) as well as those important figures (such as Vladimir Bibler, Alexander Zinoviev, Yury Lotman, Georgy Shchedrovitsky, Genrich Batishchev, Sergey Rubinstein, and others) who have often been overlooked. By introducing and examining original philosophical ideas that evolved in the Soviet period, the book confirms that not all Soviet philosophy was dogmatic and tied to orthodox Marxism and the ideology of Marxism-Leninism. It shows Russian philosophical development of the Soviet period in a new light, as a philosophy defined by a genuine discourse of exploration and intellectual progress, rather than stagnation and dogmatism. In addition to providing the historical and cultural background that explains the development of the 20th-century Russian philosophy, the book also puts the discussed ideas and theories in the context of contemporary philosophical discussions showing their relevance to nowadays debates in Western philosophy. With short biographies of key thinkers, an extensive current bibliography and a detailed chronology of Soviet philosophy, this research resource provides a new understanding of the Soviet period and its intellectual legacy 100 years after the Russian Revolution.

Thomas Aquinas's Disputed Questions on Evil is a careful and detailed analysis of the general topic of evil, including discussions on evil as privation, human free choice, the cause of moral evil, moral failure, and the so-called seven deadly sins. This collection of ten, specially commissioned new essays, the first book-length English-language study of Disputed Questions on Evil, examines the most interesting and philosophically relevant aspects of Aquinas's work, highlighting what is distinctive about it and situating it in relation not (...) only to Aquinas's other works but also to contemporary philosophical debates in metaphysics, ethics, and philosophy of action. The essays also explore the history of the work's interpretation. The volume will be of interest to researchers in a broad range of philosophical disciplines including medieval philosophy and history of philosophy, as well as to theologians. (shrink)
