Isolated habitats, the consequence of the fragmentation process, are the object of external disturbance. This divides the patch area into two zones: interior and edge. The interior-to-edge ratio quantifies the potential disturbance impact. A method is presented to calculate a reference value for the interior-to-edge ratio, based upon the minimum edge for a given interior. The method is based on pixel geometry features and mathematical morphology. A corrected interior-to-edge ratio is defined using the reference value. The method is (...) illustrated for woodlot fragments in the Belgian Kempen region. (shrink)

The Moroccan philosopher Taha Abderrahmane is one of the leading surviving philosophers of the Arab-Islamic world. His fields of study are issues such as logic, philosophy of language, moral philosophy and political theology. He built a holistic and versatile Islamic methodology in his works and formed a world of thought on the axis of trusteeship (divine contract and trust paradigm) and circulation tedavuliyya (pragmatic-word-action theory). Taha Abderrahmane has analyzed, criticized and constructed the Islamic thought tradition, which he handled with a (...) holistic view, with a versatile reference network. In addition, one of his most important contributions is that he put forward a moral philosophy in the Qurʾānic and prophetic axis. Taha Abderrahmane proved to be a prolific thinker with his thirty-five work consisting of ten thousand pages. He proposes a deliberative model of political communication in harmony with his theo-political writings and physical and metaphysical integrity. While this article aim to provide information on the main components of Abderrahmane’s paradigm of divine contract and trusteeship (i’timaniyya), essentially a theory of morality, such as political theology, linguistics, and negotiation ethics, it also tries to identify the Western references of these elements. In this context how the theory of speech acts that seems quite important in the field of modern social sciences and created by theorists such as John Searl and Austin was transformed by Taha Abderrahmane into an Islamic theory of speech is also subject to a comparative assessment. In addition, the possibility of the issue of negotiation ethics, which gained more importance with new communication theories in the West, in the axis of Islamic thought was questioned in the article. The article reviews how views on negotiation ethics are positioned by Taha Abderrahmane within the Islamic paradigm. Therefore, the article is limited in scope to Taha Abderrahmane’s references about the theories in the West. Taha Abderrahmane attempts to construct an Islamic Pragmatic or Islamic Theory of Verbal Action, with reference to Pragmatics or Theory of Speech Acts, which is a sub-branch of linguistics, but in line with principles specific to the Islamic paradigm. Taha Abderrahmane combined the Islamic concept of pragmatic with the concept of negotiation. The terms “praxis” and “praxeology [fiqh al falsafa]”, which define the framework of the Trust Paradigm and the Islamic Pragmatic Model proposed by Taha Abderrahmane, emphasize “deed” or, in other words, “action” and he is linguistically referencing the founding masters of the pragmatics field such as J. L. Austin and J. R. Searle. However, there are two other fields that constitute the main reference to his concept of praxis (action) and praxeology (action science). These are economics and philosophy. Praxeology is a scientific field that deserves to be mentioned especially with the economist Ludwig von Mises (1881-1973). According to Mises, the laws of the field about which physics, biology, and praxeology [mainly economics] provide information, are independent of human will. These are primary ontological facts that strictly limit the human power to act (Mises, 1998, 67). Taha Abderrahmane references western thinkers such as Ludwig von Mises, Jürgen Habermas, Chantal Mouffe and Hannah Arendt, as well as Islamic sources. However, the way he makes use of them takes place within the framework of criticism and analysis. He also refers to other personalities such as Jonas, Freud, Ellul, Putnam, Ricoeur and Rawls. While Taha Abderrahmane explains the process of turning words into action, he also draws on the Action Theory of Hannah Arendt (1906-1975), who was one of the children of Heidegger, such as Karl Löwith, Hans Jonas and Herbert Marcuse, and who was accepted as a real philosopher even though he rejected the title of philosopher during his lifetime. On the other hand, Taha Abderrahmane makes strong references to the basic dimension of Islam, such as “O believers! If you avoid opposing Allah; It gives you an understanding to distinguish good from bad (Al-Anfal, 8/29)” verse. He makes strong references to the supposed dimension of Islam, and in this context, he tries to create a praxis based on nature, especially based on the hadith known as nawāfil hadith. (shrink)

ABSTRACT: In its strongest unqualified form, the principle of wholistic reference is that in any given discourse, each proposition refers to the whole universe of that discourse, regardless of how limited the referents of its non-logical or content terms. According to this principle every proposition of number theory, even an equation such as "5 + 7 = 12", refers not only to the individual numbers that it happens to mention but to the whole universe of numbers. This principle, its (...) history, and its relevance to some of Oswaldo Chateaubriand's work are discussed in my 2004 paper "The Principle of Wholistic Reference" in Essays on Chateaubriand's "Logical Forms". In Chateaubriand's réplica (reply), which is printed with my paper, he raised several important additional issues including the three I focus on in this tréplica (reply to his reply): truth-values, universes of discourse, and formal ontology. This paper is self-contained: it is not necessary to have read the above-mentioned works. The principle of wholistic reference (PWR) was first put forth by George Boole in 1847 when he espoused a monistic fixed-universe viewpoint similar to the one Frege and Russell espoused throughout their careers. Later, Boole elaborated PWR in 1854 from the pluralistic multiple-universes perspective. (shrink)

Martí argued that referential intuitions are not the right kind of empirical evidence for testing theories of reference. Machery, Olivola, and De Blanc replied with a survey aimed at providing evidence that referential intuitions are in sync with truth‐value judgments and argued that truth‐value judgments provide empirical data from linguistic usage. We present the results of a survey indicating that Machery, Olivola, and De Blanc's experiment fails to overcome Martí's objection: The truth‐value judgements tested by Machery, Olivola, and De (...) Blanc do not provide data relevant for testing theories of reference. (shrink)

This work examines the influence of reference dependence, including value selection bias and congruence effects, on diagnostic reasoning. Across two studies, we explored how dependence on the initial problem structure influences the ability to solve simplified precursors to the more traditional Bayesian reasoning problems. Analyses evaluated accuracy and types of response errors as a function of congruence between the problem presentation and question of interest, amount of information, need for computation, and individual differences in numerical abilities. Across all problem (...) variations, there was consistent and strong evidence of a value selection bias in that incorrect responses almost always conformed to values that were provided in the problem rather than other errors including those related to computation. The most consistent and unexpected error across all conditions in the first experiment was that people were often more likely to utilize the superordinate value as part of their solution rather than the anticipated reference class values. This resulted in a weakened effect of congruence, with relatively low accuracy even in congruent conditions, and a dominant response error of the superordinate value. Experiment 2 confirmed that the introduction of a new sample drew attention away from the provided reference class, increasing reliance on the overall sample size. This superordinate preference error, along with the benefit of repeating the PPV reference class within the question, demonstrated the importance of reference dependence based on the salience of information within the response prompt. Throughout, higher numerical skills were generally associated with higher accuracy, whether calculations were required or not. (shrink)

This article surveys recent literature by Parsons, McGee, Shapiro and others on the significance of categoricity arguments in the philosophy of mathematics. After discussing whether categoricity arguments are sufficient to secure reference to mathematical structures up to isomorphism, we assess what exactly is achieved by recent ‘internal’ renditions of the famous categoricity arguments for arithmetic and set theory.

This book provides an incisive, basic introduction to many-valued logics and to the constructions that are "many-valued" at their origin. Using the matrix method, the author sheds light on the profound problems of many-valuedness criteria and its classical characterizations. The book also includes information concerning the main systems of many-valued logic, related axiomatic constructions, and conceptions inspired by many-valuedness. With its selective bibliography and many useful historical references, this book provides logicians, computer scientists, philosophers, and mathematicians with a valuable survey (...) of the subject.

The purpose of the paper is to refute the fregean assumption that declarative sentences refer to truth-Values. A consequence of the assumption is that the truth-Value of a declarative sentence containing another as part remains unchanged when the part is replaced by another sentence having the same truth-Value, Provided that the part as part has only customary reference and expresses a complete thought. The refutation proceeds by demonstrating this consequence to be false.

Whether a predicate is a referential expression depends upon what reference is conceived to be. Even if it is granted that reference is a relation between words and worldly items, the referents of expressions being the items to which they are so related, this still leaves considerable scope for disagreement about whether predicates refer. One of Frege's great contributions to the philosophy of language was to introduce an especially liberal conception of reference relative to which it is (...) unproblematic to suppose that predicates are referring expressions. According to this liberal conception, each significant expression in a language has its own distinctive semantic role or power, a power to effect the truth-value of the sentences in which it occurs.

We discuss Sengupta's argumentation according to which Frege was wrong identifying reference with truth-value.After stating various possible interpretations of Frege's principle of substitution, we show that there is no coherent interpretation under which Sengupta's argumentation is valid.Finally we try to show how Frege's distinction can work in the context of modern mathematics and how modern logic grasps it.

Two fundamental rules of reasoning are Universal Generalisation and Existential Instantiation. Applications of these rules involve stipulations such as ‘Let n be an arbitrary number’ or ‘Let John be an arbitrary Frenchman’. Yet the semantics underlying such stipulations are far from clear. What, for example, does ‘n’ refer to following the stipulation that n be an arbitrary number? In this paper, we argue that ‘n’ refers to a number—an ordinary, particular number such as 58 or 2,345,043. Which one? We do (...) not and cannot know, because the reference of ‘n’ is fixed arbitrarily. Underlying this proposal is a more general thesis: Arbitrary Reference : It is possible to fix the reference of an expression arbitrarily. When we do so, the expression receives its ordinary kind of semantic-value, though we do not and cannot know which value in particular it receives. Our aim in this paper is defend AR. In particular, we argue that AR can be used to provide an account of instantial reasoning, and we suggest that AR can also figure in offering new solutions to a range of difficult philosophical puzzles.

Reference is a central topic in philosophy of language, and has been the main focus of discussion about how language relates to the world. R. M. Sainsbury sets out a new approach to the concept, which promises to bring to an end some long-standing debates in semantic theory.There is a single category of referring expressions, all of which deserve essentially the same kind of semantic treatment. Included in this category are both singular and plural referring expressions, complex and non-complex (...) referring expressions, and empty and non-empty referring expressions. Referring expressions are to be described semantically by a reference condition, rather than by being associated with a referent. In arguing for these theses, Sainsbury's book promises to end the fruitless oscillation between Millian and descriptivist views. Millian views insist that every name has a referent, and find it hard to give a good account of names which appear not to have referents, or at least are not known to do so, like ones introduced through error, ones where it is disputed whether they have a bearer and ones used in fiction. Descriptivist theories require that each name be associated with some body of information. These theories fly in the face of the fact names are useful precisely because there is often no overlap of information among speakers and hearers. The alternative position for which the book argues is firmly non-descriptivist, though it also does not require a referent. A much broader view can be taken of which expressions are referring expressions: not just names and pronouns used demonstratively, but also some complex expressions and some anaphoric uses of pronouns.Sainsbury's approach brings reference into line with truth: no one would think that a semantic theory should associate a sentence with a truth value, but it is commonly held that a semantic theory should associate a sentence with a truth condition, a condition which an arbitrary state of the world would have to satisfy in order to make the sentence true. The right analogy is that a semantic theory should associate a referring expression with a reference condition, a condition which an arbitrary object would have to satisfy in order to be the expression's referent.Lucid and accessible, and written with a minimum of technicality, Sainsbury's book also includes a useful historical survey. It will be of interest to those working in logic, mind, and metaphysics as well as essential reading for philosophers of language. (shrink)

In this paper, I revisit Frege's theory of sense and reference in the constructive setting of the meaning explanations of type theory, extending and sharpening a program–value analysis of sense and reference proposed by Martin-Löf building on previous work of Dummett. I propose a computational identity criterion for senses and argue that it validates what I see as the most plausible interpretation of Frege's equipollence principle for both sentences and singular terms. Before doing so, I examine Frege's implementation (...) of his theory of sense and reference in the logical framework of Grundgesetze, his doctrine of truth values, and views on sameness of sense as equipollence of assertions.

What are values? Where do our values come from? How do our values make a difference to education? For educational leaders to achieve distinction in their practice, it is vital to establish their own clear sense of values rather than reacting to the implicit values of others. This engaging book guides readers in thinking for themselves about the values they bring to their task and the values they intend to promote. Crucially, the book (...) promotes critical thought and constructive analysis about the underlying values involved with: - aims and moral purpose in education - individual qualities in educational leadership - vision in education - school ethos and culture - the school as an educational community. By inviting reflection using valuable case studies and work-through activities, as well as referring to a wide range of academic literature, this book will be an important resource for those working towards professional qualifications such as NPQH, and invaluable for anyone aspiring to excellence in educational leadership.

Experiments on theories of reference have mostly tested referential intuitions. We think that experiments should rather be testing linguistic usage. Substantive Aim (I): to test classical description theories of proper names against usage by “elicited production.” Our results count decisively against those theories. Methodological Aim (I): Machery, Olivola, and de Blanc (2009) claim that truth-value judgment experiments test usage. Martí (2012) disagrees. We argue that Machery et al. are right and offer some results that are consistent with that conclusion. (...) Substantive Aim (II): Machery et al. provide evidence that the usage of a name varies, being sometimes descriptive, sometimes not. In seven out of eight tests of usage, we did not replicate this variation. Methodological Aim (II): to test the reliability of referential intuitions by comparing them with linguistic usage. Earlier studies led us to predict that we would find those intuitions unreliable, but we did not. Our results add to evidence that tests of referential intuition are susceptible to unpredictable wording effects. (shrink)

This chapter talks about the power of music, how characters in South Park use it in telling stories, and how music conveys ideas in the context of Western philosophy. But South Park does raise questions about music that philosophers— particularly Plato—have dealt with again and again. Despite their flaws, these Greek thinkers' views were instrumental to asking questions about music's impact (often referred to as ethos), its mathematical properties in relation to the universe, and how these two aspects interact with (...) one another. Phil Collins and Asia may not survive history's merciless aesthetic filter, just as the aulos instrument vanished long ago, but where the underlying philosophy is concerned, the issues are timeless.

The rift between science and religion needs to be assessed not merely on pragmatic grounds, on the basis of the effect of scientific versus religious beliefs on people's behavior, as John Caiazza's essay does, but also and above all in regard to the cogency of the respective beliefs in reference to what we can reasonably assume is the true face of reality. About such truth value, the conflict is not irremediable; there are elements of belief regarding the nature of (...) reality that are strikingly similar regardless of whether one arrived at them on the basis of faith in revealed knowledge or on the basis of knowledge acquired by reasoning from or in reference to experience. Two such items are selected here by way of example: belief that in certain states of mind and consciousness individuals can experience union with something larger or deeper than themselves, and belief that the universe we inhabit is the result of an original creative act.

Stocker intends this book to redress the common failures of contemporary moral philosophers to see the importance of emotions for their field. His aim is not merely to point out deficiencies in current thinking about emotions and their place in ethics, however. It is also to show how emotions are important for ethics. The book is divided into ten chapters, four of which are written in collaboration with Elizabeth Hegeman, an anthropologist and psychoanalyst. The first seven present criticisms of current (...) thinking and argue for some general theses about the way emotions are related to values. The last three examine specific emotions, notably, compassion, pity, pride, shame, and anger. They serve to substantiate the general theses about the way emotions are related to values that the first seven chapters promote. In this review I will concentrate on the material in these first seven chapters. Though some of it is jointly authored, I will for convenience' sake mostly refer just to Stocker as the author.

Family life and one's career are incomparable values for him/her. The whole topic of incomparability of desires is veiled in confusion and controversy. Some people deny that there are any incomparable desires. This chapter explains meaning of incomparability, discusses incomparability as a fact of life that many of the desires are incomparable, and also examines why incomparability makes an enormous difference to decision‐making what patterns of incomparability the desires exhibit. The first dimension of incomparability is depth: how much thought (...) and how many comparisons with other wants the inability to choose will survive. Another dimension is generality, whether the incomparability concerns just individual wants or also the values that usually underlie them. The significance of some patterns of incomparability becomes clearer if one add another ingredient to the brew: the influence of beliefs on desires. The chapter considers an example to illustrate this influence. (shrink)

This article introduces three arguments that share a single conclusion: that a comprehensive science of language cannot describe relations of semantic reference, i.e. word–world relations. Spelling this out, if there is to be a genuine science of linguistic meaning, then a theory of meaning cannot involve assigning external, real-world, objects to names, nor sets of external objects to predicates, nor truth values to sentences. Most of the article tries to explain and defend this broad conclusion. The article also (...) presents, in a very limited way, a positive alternative to external-referent semantics for expressions. This alternative has two parts: first, that the meanings of words and sentences are mental instructions, not external things; second, that it is people who refer by using words and sentences, and word/sentence meanings play but a partial role in allowing speakers to talk about the world.

“Sentiment” is a term of art, intended to refer to object-directed, irruptive states, that occur in relatively transient bouts involving positive or negative affect, and that typically involve a distinctive motivational profile. Not all the states normally called “emotions” are sentiments in the sense just characterized. And all the terms for sentiments are sometimes used in English to refer to longer lasting attitudes. But this discussion is concerned with boutish affective states, not standing attitudes. That poses some challenges that will (...) be my focus here. Rational sentimentalism is a cousin of fitting attitude theories of value, but other fitting attitude theories appeal to attitudes that are widely assumed to be governable by certain kinds of judgments. The basic challenge is this: are these boutish sentiments the sorts of things that we can and do regulate in the ways that are required for treating ‘shameful’, ‘funny’, ‘disgusting’ and the like as values? In what follows I briefly sketch some necessary conditions on treating something as a value, from which it emerges that treating sentimental values as values requires regulating the sentiments for fittingness. The rest of the paper is devoted to two ways of understanding how such regulation might work. I argue first that sentiments are susceptible to regulation by evaluative judgment, though perhaps not in quite the same way that philosophers have thought “judgment-sensitive attitudes” are regulated by judgment. I then suggest more tentatively that sentiments are also susceptible to regulation for fittingness in a different way: by educating sensibilities. (shrink)

It is a commonplace that ‘autonomy’ has several different senses in contemporary moral and political discussion. The term’s original meaning was political: a right assumed by states to administer their own affairs. It was not until the nineteenth century that ‘autonomy’ came (in English) to refer also to the conduct of individuals, and even then there were, as now, different meanings.1 Odd as it may seem from our perspective, one that was in play from the beginning was Kant’s notion of (...) “autonomy of the will,”2 as Kant defined it, “the property of the will by which it is a law to itself independently of any property of the objects of volition” (4:440).3That’s a mouthful, to say the least.

This paper proceeds from an analysis (Callaway 1992, pp. 239-240) of a role of conflict in the origin of value commitments, a pervasive sociological pattern in the development of unifying group values which transforms personal conflicts, or differences, into large-scale collective conflicts. I have urged that these forces are capable of distorting even the cognitive processes of science and that they are a chief reason why value claims are regarded as incapable of objective evaluation. The thesis of the present (...) paper is that romantic collectivism (uncritical attachment to an identification group) renders members passive with respect to the ideals or content embodied in collective identity and that this is often exploited to convert groups into instruments of personal power. The issue is examined by reference to Reinhold Niebuhr's 1932 thesis of the inevitability of group egoism and inter-group conflicts and an opposing pragmatist conception of moral development, self-identity, and the individual's relationship to reference communities.

The value of applied philosophy is often taken to consist in its contribution to our understanding of practical issues with which applied philosophy engages and in its contribution to their satisfactory resolution. This chapter examines the relationship between the nature of applied philosophy and its value. It regards the value of applied philosophy as dependent both on its philosophical quality and on its contribution to the understanding and (potential) resolution of practical issues with which it engages. These dual points of (...) reference are difficult simultaneously to fulfill and arguably sometimes in tension with one another. The chapter takes issue with the idea that the value of applied philosophy consists, or ought to consist, in its direct impact on actual policy or practice. (shrink)

In recent years the distinction between agent-relative and agent-neutral reasons has been taken by many to play a key role in distinguishing deontology from consequentialism. It is central to all universalist consequentialist theories that value is determined impersonally; the real value of any state of affairs does not depend on the point of view of the agent. No reference, therefore, to the agent or to his or her position in the world need enter into a consequentialist understanding of what (...) makes an action right or wrong or morally permissible. Consequentialism thus provides an agent-neutral account of both the right and the good. (shrink)

Philosophers have used the terms 'impersonal' and 'personal value' to refer to, among others things, whether something's value is universal or particular to an individual. In this paper, I propose an account of impersonal value that, I argue, better captures the intuitive distinction than potential alternatives, while providing conceptual resources for moving beyond the traditional stark dichotomy. I illustrate the practical importance of my theoretical account with reference to debate over the evaluative scope of cultural heritage.

Theories of partial reference have been developed in order to retrospectively interpret rather stubborn past scientific theories like Newtonian dynamics and the phlogiston theory in a realist way, i.e., as approximately true. This is done by allowing for a term to refer to more than one entity at the same time and by providing semantic structures that determine the truth values of sentences containing partially referring terms. Two versions of theories of partial reference will be presented, a (...) conjunctive (by Hartry Field, 1973) and a disjunctive one (by Christina McLeish, 2006). In this paper, I will analyze them with regard to modal and epistemic aspects of those theories. It will be argued that a) theories of partial reference are (surprisingly) compatible with the rigidity of natural kind terms but face a weaker form of the so called “no-failures-of-reference-problem” and b) that the disjunctive account of partial reference suffers from a serious weakness: the impossibility of discriminating between descriptions that fix the reference of a term and those merely associated with it leads to the unacceptable result that past scientific theories containing such partially referring terms will come out as epistemically necessary, i.e., as a priori true.

ABSTRACT:Psychedelics, including psilocybin, and other consciousness-altering compounds such as 3,4-methylenedioxymethamphetamine (MDMA), currently are being scientifically investigated for their potential therapeutic uses, with a primary focus on measurable outcomes: for example, alleviation of symptoms or increases in self-reported well-being. Accordingly, much recent discussion about the possible value of these substances has turned on estimates of the magnitude and duration of persisting positive effects in comparison to harms. However, many have described the value of a psychedelic experience with little or no (...) class='Hi'>reference to such therapeutic benefits, instead seeming to find the experience valuable in its own right. How can we make sense of such testimony? Could a psychedelic experience be valuable even if there were no persisting beneficial effects? If so, how? Using the concept of psychological richness, combined with insights from the philosophy of aesthetics and the enhancement literature, this essay explores potential sources of value in the acute subjective experience, apart from the value derived from persisting beneficial effects.

The paper offers a survey of the debate on the introduction, in the Preamble of the Treaty establishing a Constitution for Europe, of references to God and Europe’s Christian tradition. It examines the question of European identity and values which motivates these proposals in relation to (1) the nature of the EU as an essentially political construction; (2) the issue of human rights in the EU; (3) the protection of cultural and religious diversity within the EU. The study shows (...) that the confessionalization of Europe promoted by strong churches on the Continent, which are legitimate actors of civil society, betray a failure to understand the logic of the European construction. To the extent to which they represent an attempt to secure a privileged position with respect to other religious or non-religious actors, they run against the functional principles and values of the Union.

On some formulations of Direct Reference the semantic value, relative to a context of utterance, of a rigid singular term is just its referent. In response to the apparent possibility of a difference in truth value of two sentences just alike save for containing distinct but coreferential rigid singular terms, some proponents of Direct Reference have held that any two such sentences differ only pragmatically. Some have also held, more specifically, that two such sentences differ by conveying distinct (...) conversational implicata, and that a conflation of implicatum with semantic content leads speakers to judge such sentences capable of differing in truth value. It is argued here that this latter defense of Direct Reference employs false explanans, on the ground that speakers conflate semantic content with implicatum only in quite special cases, and we have independent grounds for thinking that sentences reporting speech acts and attitudes are not cases of this sort.

The purpose of this paper is to open for investigation a range of phenomena familiar from dynamical systems or chaos theory which appear in a simple fuzzy logic with the introduction of self-reference. Within that logic, self-referential sentences exhibit properties of fixed point attractors, fixed point repellers, and full chaos on the [0, 1] interval. Strange attractors and fractals appear in two dimensions in the graphing of pairs of mutually referential sentences and appear in three dimensions in the graphing (...) of mutually referential triples.
