Breaking new ground in the debate about the relation of mind and body, David Armstrong's classic text - first published in 1968 - remains the most compelling and comprehensive statement of the view that the mind is material or physical. In the preface to this new edition, the author reflects on the book's impact and considers it in the light of subsequent developments. He also provides a bibliography of all the key writings to have appeared in the materialist debate.

The most compelling extant accounts of explanation casts all explanations as causal. Yet there are sciences, theoretical population biology in particular, that explain their phenomena by appeal to statistical, non-causal properties of ensembles. I develop a generalised account of explanation. An explanation serves two functions: metaphysical and cognitive. The metaphysical function is discharged by identifying a counterfactually robust invariance relation between explanans event and explanandum. The cognitive function is discharged by providing an appropriate description of this relation. I offer examples (...) of explanations from portfolio theory and population genetics that meet this characterisation. In each case the invariance relation holds between a statistical property of an ensemble and a change in structure of the ensemble. In neither case, however, does the statistical property cause the outcome it explains. There are genuine statistical, non-causal scientific explanations. (shrink)

I argue that recent advances in developmental biology demonstrate the inadequacy of suborganismal mechanism. The category of the organism, construed as a ’natural purpose’ should play an ineliminable role in explaining ontogenetic development and adaptive evolution. According to Kant the natural purposiveness of organisms cannot be demonstrated to be an objective principle in nature, nor can purposiveness figure in genuine explain. I attempt to argue, by appeal to recent work on self-organization, that the purposiveness of organisms is a natural phenomenon (...) and, by appeal to the apparatus of invariance explanation, that biological purposiveness provides genuine, ineliminable biological explanations.

This article explores hospitality in relation to migration within the framework of spatial theory and calling. The material of the article is based on fieldwork carried out in the Nordic borderlands and conducted in relation to a research project exploring Nordic hospitality. The concept and context of the borderland, as well as the methodological development of this project, are based on spatial theory, phenomen-ology and theology. The material discussed are excerpts from a small fieldwork narrative about borderland experiences, and interviews (...) regarding events that took place on the Russian–Norwegian border during the so-called refugee crisis in 2015–16. The article aims at, by means of these narrative excerpts, exploring how conceptualisations of hospitality, by discussing them in relation to the concept of calling from Scandinavian creation theology, may contribute to extensions of both concepts.

This contribution to the Common Knowledge symposium “Fuzzy Studies” argues that the inclusion of space in form brings varying degrees of fuzziness and fluidity to all natural identities. Such inclusion is vital to evolutionary creativity, from subatomic to cosmic scales of natural energy flow. Examples abound throughout the natural world of indeterminate forms and processes unclassifiable under any of the discrete categories that are preferred and imposed by definitive theoretical models. Here, the much-neglected kingdom of the fungi is used to (...) illustrate the workings of a logic of fluid boundaries. (shrink)

This paper provides equational semantics for Dung's argumentation networks. The network nodes get numerical values in [0,1], and are supposed to satisfy certain equations. The solutions to these equations correspond to the ?extensions? of the network. This approach is very general and includes the Caminada labelling as a special case, as well as many other so-called network extensions, support systems, higher level attacks, Boolean networks, dependence on time, and much more. The equational approach has its conceptual roots in the nineteenth (...) century following the algebraic equational approach to logic by George Boole, Louis Couturat, and Ernst Schroeder. (shrink)

Argues that a set is the mereological whole of the singleton sets of its members (following Lewis's Parts of Classes), and that the singleton set of X is the state of affairs of X's having some unit-making property.

Truths are determined not by what we believe, but by the way the world is. Or so realists about truth believe. Philosophers call such theories correspondence theories of truth. Truthmaking theory, which now has many adherents among contemporary philosophers, is the most recent development of a realist theory of truth, and in this book D. M. Armstrong offers the first full-length study of this theory. He examines its applications to different sorts of truth, including contingent truths, modal truths, truths about (...) the past and the future, and mathematical truths. In a clear, even-handed and non-technical discussion he makes a compelling case for truthmaking and its importance in philosophy. His book marks a significant contribution to the debate and will be of interest to a wide range of readers working in analytical philosophy. (shrink)

In this important study D. M. Armstrong offers a comprehensive system of analytical metaphysics that synthesises but also develops his thinking over the last twenty years. Armstrong's analysis, which acknowledges the 'logical atomism' of Russell and Wittgenstein, makes facts the fundamental constituents of the world, examining properties, relations, numbers, classes, possibility and necessity, dispositions, causes and laws. All these, it is argued, find their place and can be understood inside a scheme of states of affairs. This is a comprehensive and (...) rigorously this-worldly account of the most general features of reality, argued from a distinctive philosophical perspective, and it will appeal to a wide readership in analytical philosophy.

ABSTRACT Translating archaic Greek philosophies presents a complex of opportunities and challenges for translators, several of which are regularly overlooked. Among these figure prominently the culture and thematics of oralcy and the predisciplinarity in which early Greek thinking took shape. Additionally, translators engaged with early Greek thinking face layers of interpretive history and expectations that can determine the scope of possible translation, which, in turn, limits the range of interpretive possibilities. Yet their predisciplinary or at least hybrid modes summon a (...) broad attention to contexts of language, forms, and meanings that may challenge, or even disrupt, the predominant lines of inquiry and interpretation. How can translation motivated by the oralcy and predisciplinarity of archaic Greece open new directions for interpretation of the early Greek thinkers? Ranging through Anaximander, Xenophanes, Heraclitus, Parmenides, and others, this article articulates some possibilities for translating on and beyond the boundaries of philosophy. (shrink)

This is Part 1 of a paper on fibred semantics and combination of logics. It aims to present a methodology for combining arbitrary logical systems L i , i ∈ I, to form a new system L I . The methodology `fibres' the semantics K i of L i into a semantics for L I , and `weaves' the proof theory (axiomatics) of L i into a proof system of L I . There are various ways of doing this, we (...) distinguish by different names such as `fibring', `dovetailing' etc, yielding different systems, denoted by L F I , L D I etc. Once the logics are `weaved', further `interaction' axioms can be geometrically motivated and added, and then systematically studied. The methodology is general and is applied to modal and intuitionistic logics as well as to general algebraic logics. We obtain general results on bulk, in the sense that we develop standard combining techniques and refinements which can be applied to any family of initial logics to obtain further combined logics. The main results of this paper is a construction for combining arbitrary, (possibly not normal) modal or intermediate logics, each complete for a class of (not necessarily frame) Kripke models. We show transfer of recursive axiomatisability, decidability and finite model property. Some results on combining logics (normal modal extensions of K) have recently been introduced by Kracht and Wolter, Goranko and Passy and by Fine and Schurz as well as a multitude of special combined systems existing in the literature of the past 20-30 years. We hope our methodology will help organise the field systematically. (shrink)

Images permeate and propel archaic thinking in diverse ways. How do philosophic texts from the Greek archaic period (ca. eighth through early-fifth centu­ries BCE) conceive of images and what do images accomplish in archaic philosophies? In what ways can attention to images in philosophic texts open perspectives onto the relations of myth, poetry, and philosophy in the archaic Greek period? With these questions guiding the inquiry, this paper explores texts from various traditions jointly related within the archaic Aegean cultural matrix. (...) Texts from what might be termed philosophy’s prehistory, such as the ancient Egyptian Leiden Hymns and Odysseia, pro­vide important context for understanding the continuity and development of images.

In this short text, a distinguished philosopher turns his attention to one of the oldest and most fundamental philosophical problems of all: How it is that we are able to sort and classify different things as being of the same natural class? Professor Armstrong carefully sets out six major theories—ancient, modern, and contemporary—and assesses the strengths and weaknesses of each. Recognizing that there are no final victories or defeats in metaphysics, Armstrong nonetheless defends a traditional account of universals as the (...) most satisfactory theory we have.This study is written for advanced students, but as Armstrong goes considerably beyond his earlier work on this topic, it will interest professional scholars as well. Carefully plotted and clearly written, Universals is both a paradigm of exposition and a case study on the value of careful analysis of fundamental issues in philosophy. (shrink)

Objective: To evaluate existing ethical guidelines for the treatment of hunger strikers in light of findings on psychological changes that accompany the cessation of food intake.Design: Electronic databases were searched for editorials and ethical proclamations on hunger strikers and their treatment; studies of voluntary and involuntary starvation, and legal cases pertaining to hunger striking. Additional studies were gathered in a snowball fashion from the published material cited in these databases. Material was included if it provided ethical or legal guidelines; shed (...) light on psychological changes accompanying starvation, or illustrated the practice of hunger striking. Authors’ observations, opinions, and conclusions were noted.Conclusions: Although the heterogeneous nature of the sources precluded statistical analysis, starvation appears to be accompanied by marked psychological changes. Some changes clearly impair competence, in which case physicians are advised to follow advance directives obtained early in the hunger strike. More problematic are increases in impulsivity and aggressivity, changes which, while not impairing competence, enhance the likelihood that patients will starve themselves to death. (shrink)

It is argued that it is possible that all properties are categorical, contrary to the arguments of Franklin that there must be dispositionality "all the way down". The tasks for which dispositionality is alleged to be needed can be fulfilled by laws of nature, which are categorical relations between universals.

Spanning a wide range of texts, figures, and traditions from the ancient Mediterranean world, this volume gathers far-reaching, interdisciplinary papers on Greek philosophy from an international group of scholars. The book's sixteen chapters address an array of topics and themes, extending from the formation of philosophy from its first stirrings in archaic Greek as well as Egyptian, Persian, Mesopotamian, and Indian sources, through central concepts in ancient Greek philosophy and literatures of the classical period and into the Hellenistic age. Studies (...) in Ancient Greek Philosophy offers both in-depth, rigorous, attentive investigations of canonical texts in western philosophy, such as Plato's Phaedo, Gorgias, Republic, Phaedrus, Protagoras and the Metaphysics, De Caelo, Nichomachean Ethics, Generation and Corruption of Aristotle's corpus, as well as inquiries that reach back into the rich archives of the Mediterranean Basin and forward into the traditions of classical philosophy beyond the ancient world. Studies in Ancient Greek Philosophy is of interest to students and scholars working on different aspects of ancient Greek philosophy, as well as ancient philosophy more broadly. (shrink)

Quantum mechanics is a fundamentally probabilistic theory (at least so far as the empirical predictions are concerned). It follows that, if one wants to properly understand quantum mechanics, it is essential to clearly understand the meaning of probability statements. The interpretation of probability has excited nearly as much philosophical controversy as the interpretation of quantum mechanics. 20th century physicists have mostly adopted a frequentist conception. In this paper it is argued that we ought, instead, to adopt a logical or Bayesian (...) conception. The paper includes a comparison of the orthodox and Bayesian theories of statistical inference. It concludes with a few remarks concerning the implications for the concept of physical reality. (shrink)

This paper argues that the foundations of our knowledge are the bed-rock certainties of ordinary life, what may be called the Moorean truths. Beyond that are the well-established results within the empirical sciences, and whatever has been proved in the rational sciences of mathematics and logic. Otherwise there is only belief, which may be more or less rational. A moral drawn from this is that dogmatism should be moderated on all sides.

It is not certain when or by whom S0009838800011642_inline1 and S0009838800011642_inline2 were first technically distinguished as genus and species. The distinction does not appear in Plato's extant writings, whereas Aristotle seems to take it for granted in the Topics, which is usually regarded as among his earliest treatises. In his dialogues Plato seems able to use S0009838800011642_inline3 interchangeably to denote any group or division in a diairesis, including the group that is to be divided.
