Two entities are weakly discernible when an irreflexive and symmetric relation holds between them. That weak discernibility holds in quantum mechanics is fairly uncontroversial nowadays. The ontological consequences of weak discernibility, however, are far from clear. Part of the literature seems to imply that weak discernibility points to a definite metaphysics to quantum mechanics. In this paper we shall discuss the metaphysical contribution of weak discernibility to quantum mechanics and argue that, contrary (...) to part of current literature, it does not provide for a fully naturalistic determination of metaphysics. Underdetermination of the metaphysics still plagues the way of the naturalist. (shrink)

Simon Saunders argues that, although distinct objects must be discernible, they need only be weakly discernible (Saunders 2003, 2006a). I will argue that this combination of views is unmotivated: if there can be objects which differ only weakly, there can be objects which don’t differ at all.

Muller and Saunders ([2008]) purport to demonstrate that, surprisingly, bosons and fermions are discernible; this article disputes their arguments, then derives a similar conclusion in a more satisfactory fashion. After briefly explicating their proof and indicating how it escapes earlier indiscernibility results, we note that the observables which Muller and Saunders argue discern particles are (i) non-symmetric in the case of bosons and (ii) trivial multiples of the identity in the case of fermions. Both problems undermine the claim that they (...) have shown particles to be physically discernible. We then prove two results concerning observables that are truly physical: one showing when particles are discernible and one showing when they are not (categorically) discernible. Along the way we clarify some frequently misunderstood issues concerning the interpretation of quantum observables. 1 Background2 Criticisms2.1 Bosons2.2 Fermions3 Reformulating the Insight3.1 What weakly discerns?3.2 General results4 Conclusion.

Saunders has recently claimed that “identical quantum particles” with an anti-symmetric state (fermions) are weakly discernible objects, just like irreflexively related ordinary objects in situations with perfect symmetry (Black’s spheres, for example). Weakly discernible objects have all their qualitative properties in common but nevertheless differ from each other by virtue of (a generalized version of) Leibniz’s principle, since they stand in relations an entity cannot have to itself. This notion of weak discernibility has been criticized as question begging, (...) but we defend and accept it for classical cases likes Black’s spheres. We argue, however, that the quantum mechanical case is different. Here the application of the notion of weak discernibility indeed is question begging and in conflict with standard interpretational ideas. We conclude that the introduction of the conceptual resource of weak discernibility does not change the interpretational status quo in quantum mechanics. (shrink)

Some authors have attempted to defend Leibniz’s Identity of Indiscernibles through weak discernibility. The idea is that if there is a symmetric, nonreflexive physical relation that holds between two particles, then those particles cannot be identical. In this article I focus only on Muller and Saunders’s account and argue that the means by which they achieve weak discernibility is not through a quantum mechanical observable but an alternate mathematical construction that is both unorthodox and incomplete.

The Weak Principle of the Identity of Indiscernibles (weak PII), states that numerically distinct items must be discernible by a symmetrical and irreflexive relation. Recently, some authors have proposed that weak PII holds in non relativistic quantum mechanics, contradicting a long tradition claiming PII to be simply false in that theory. The question that arises then is: are relations allowed in the scope of PII? In this paper, we propose that quantum mechanics does not help us in (...) deciding matters concerning that problem, since that is a metaphysical problem rather than a quantum mechanical one. We argue further that weak PII is unmotivated on metaphysical grounds. We examine three metaphysical theses (bundle theory, counting, empiricism) that may provide reasons for one to sustain PII, and we conclude that weak PII gets no independent motivation from them.

De Clercq (2012) proposes a strategy for denying purported graph-theoretic counterexamples to the Principle of the Identity of Indiscernibles (PII), by assuming that any vertex is contained by multiple graphs. Duguid (2016) objects that De Clercq fails to show that the relevant vertices are discernible. Duguid is right, but De Clercq’s strategy can be rescued. This note clarifies what assumptions about graph ontology are needed by De Clercq, and shows that, given those assumptions, any two vertices are weakly discernible, and (...) so are not counterexamples to the version of PII that requires only weak discernibility. (shrink)

In this article we investigate putative counterexamples to Leibniz’s principle of the Identity of Indiscernibles. In particular, we look at the status of spacetime points: although these all possess exactly the same properties in symmetrical spacetimes and thus seem indiscernible, there are certainly more than one of them. However, we shall defend Leibniz’s principle, even for such highly symmetrical cases. Part of our strategy will be to invoke the notion of “weak discernibility”, as proposed in the recent literature. (...) Weakly discernible objects share all their properties but stand in irreflexive relations to one another—this irreflexivity makes it possible to show that Leibniz's principle implies their numerical diversity. However, we shall argue that this notion of weak discernibility only serves its purpose if it is supplemented by a criterion of physical meaningfulness of the relations and relata in question; and that in the final analysis weak discernibility only helps out when it can be seen as a degenerate case of strong, absolute discernibility. The case of spacetime points is an example of such a situation. (shrink)

Saunders' recent arguments in favour of the weak discernibility of (certain) quantum particles seem to be grounded in the 'generalist' view that science only provides general descriptions of the worlIn this paper, I introduce the ‘generalist’ perspective and consider its possible justification and philosophical basis; and then look at the notion of weak discernibility. I expand on the criticisms formulated by Hawley (2006) and Dieks and Veerstegh (2008) and explain what I take to be the basic (...) problem: that the properties invoked by Saunders cannot be pointed to as ‘individuators’ of otherwise indiscernible (and thus numerically identical) entities because their ontological status remains underdetermined by the evidence and the established interpretation of the theory. In addition to to this, I suggest that Saunders does not deal adequately with bosons, and cannot do so exactly because he subscribes to PII and the generalist picture. The last part of the paper contains a critical examination of the claim (or at least implicit assumption) that the generalist picture should be regarded as obviously compelling by the modern-day empiricist.

Bundle Theory is the view that every concrete particular object is solely constituted by its universals. This theory is often criticized for not accommodating the possibility of symmetrical universes, such as one that contains two indiscernible spheres two meters from each other in otherwise empty space. One bundle theoretic solution to this criticism holds that the fact that the spheres stand in a weakly discerning—i.e., irreflexive and symmetric—relation, such as being two meters from, is sufficient for the numerical diversity of (...) the spheres. For this solution to be effective, however, it should be established that weak discernibility not only necessitates but also explains numerical diversity. In this paper, I argue that the fact that two objects have a certain distance between them does explain why they are non-identical. I also argue that the worry that the weak discernibility approach has some circularity problems is not well-founded. (shrink)

Questions about the relation between identity and discernibility are important both in philosophy and in model theory. We show how a philosophical question about identity and dis- cernibility can be ‘factorized’ into a philosophical question about the adequacy of a formal language to the description of the world, and a mathematical question about discernibility in this language. We provide formal definitions of various notions of discernibility and offer a complete classification of their logical relations. Some new and (...) surprising facts are proved; for instance, that weak dis- cernibility corresponds to discernibility in a language with constants for every object, and that weak discernibility is the most discerning nontrivial discernibility relation. (shrink)

In a series of recent papers, Simon Saunders, Fred Muller, and Michael Seevinck have collectively argued, against the folklore, that some nontrivial version of Leibniz’s principle of the identity of indiscernibles is upheld in quantum mechanics. They argue that all particles—fermions, paraparticles, anyons, even bosons—may be weakly discerned by some physical relation. Here I show that their arguments make illegitimate appeal to nonsymmetric, that is, permutation-noninvariant, quantities and that therefore their conclusions do not go through. However, I show that alternative, (...) symmetric quantities may be found to do the required work. I conclude that the Saunders-Muller-Seevinck heterodoxy can be saved. (shrink)

We maximally extend the quantum‐mechanical results of Muller and Saunders ( 2008 ) establishing the ‘weak discernibility’ of an arbitrary number of similar fermions in finite‐dimensional Hilbert spaces. This confutes the currently dominant view that ( A ) the quantum‐mechanical description of similar particles conflicts with Leibniz’s Principle of the Identity of Indiscernibles (PII); and that ( B ) the only way to save PII is by adopting some heavy metaphysical notion such as Scotusian haecceitas or Adamsian primitive (...) thisness. We take sides with Muller and Saunders ( 2008 ) against this currently dominant view, which has been expounded and defended by many. *Received July 2008; revised May 2009. †To contact the authors, please write to: F.

One of the reasons provided for the shift away from an ontology for physical reality of material objects & properties towards one of physical structures & relations (Ontological Structural Realism: OntSR) is that the quantum-mechanical description of composite physical systems of similar elementary particles entails they are indiscernible. As material objects, they 'whither away', and when they wither away, structures emerge in their stead. We inquire into the question whether recent results establishing the weak discernibility of elementary particles (...) pose a threat for this quantum-mechanical reason for OntSR, because precisely their newly discovered discernibility prevents them from 'whithering away'. We argue there is a straightforward manner to consider the recent results as a reason in favour of OntSR rather than against it. (shrink)

Recently, Simon Saunders has applied Quine's account of discernibility to the theory of identical particles, ultimately to argue that quanta can be weakly discernible. I want to expand on this work along two axes. First, to explain how the results apply to higher kinds of statistics -- 'quarticles'. Second, to dispute the claim that quanta are weakly discernible: I question whether the operators used to discern the particles do not represent the properties that they are claimed to.

Ryan, Tom 'Accompanying, Discerning and Integrating Weakness' is the 'contested' chapter 8 of Pope Francis's postsynodal allocution 'The Joy of Love'. This collegial document can be approached from various perspectives, for example, in its historical and theological context; in its significance for moral theology; in its reception within local churches. The aim here is pastoral, namely, to clarify the chapter's content and, specifically, its implications for the faithful and those engaged in pastoral ministry.

Broadly speaking, there are three views on whether Leibniz’s Principle of the Identity of Indiscernibles (PII) is violated in the case of similar particles. According to the earliest view, PII is always violated (call this the no discernibility view); according to the more recent weak discernibility view, PII is at least valid in a weak sense. No and weak discernibility have been referred to as orthodoxy. Steven French has argued that although PII is violated, (...) similar particles can still be regarded as individuals, or, alternatively, as non-individuals: French famously concluded therefore that metaphysics is underdetermined by physics. Call this thesis orthodox underdetermination. Most recently, some authors have turned against orthodoxy by arguing that PII is valid in more than a weak sense – call this the new discernibility view, also referred to as heterodoxy. Since heterodoxy is backed up by physical considerations, metaphysics now seems to be determined by physics: physics indicates that PII is valid. In this paper, I argue that with respect to entangled states, there are two ways to establish PII’s validity, which yield two different ontological interpretations of entanglement. Therefore, a form of underdetermination returns within the heterodox framework. I argue that heterodox underdetermination deserves some attention, because the two ontological interpretations might yield different explanations of the violation of Bell inequalities. (shrink)

In this paper we discuss the definitional problems of altered states of consciousness and their potential relevance in phenomenological investigation. We suggest that visionary states or visionary phantasy working induced by psychedelics, as extraordinary types of altered states, are appropriate subjects for phenomenological analysis. Naturally, visionary states are not quite ordinary workings of the human mind, however certain cognitive psychological and evolutionary epistemological investigations show that they can give new insights into the nature of consciousness. Furthermore, we suggest that contemporary (...) inquiries concerning altered states in consciousness studies give an opportunity to complete the contemporary phenomenological investigations of phantasy with the notion of visionary phantasy. Here we propose that the similarities and differences between Dieter Lohmar’s weak phantasy and Benny Shanon’s concept of vision are precisely discernible, and, consequently, it may be possible that weak phantasy and visionary phantasy are situated on the two outermost poles of the colorful spectrum of phantasy activity.

There is more than one way to say that composition is identity. Yi has distinguished the Weak Composition thesis from the Strong Composition thesis and attributed the former to David Lewis while noting that Lewis associates something like the latter with me. Weak Composition is the thesis that the relation between the parts collectively and their whole is closely analogous to identity. Strong Composition is the thesis that the relation between the parts collectively and their whole is identity. (...) Yi is right that Strong Composition does not fully reflect my view. We must recognize further what, borrowing Lewis's characterization, could be called the "stronger, and stranger" Composition thesis, or what I'll call the Stronger Composition thesis for short. On Strong Composition, it is only collectively that the parts are identical with the whole. On Stronger Composition, they are individually identical with it as well. I will explain and motivate this thesis. (shrink)

This article discusses madness and saintliness in Dostoevsky’s novels and investigates how the madman and the saint discern between good and evil. I first explore the metaphysical, spiritual, and moral universe of Dostoevsky’s characters by drawing on William Desmond’s philosophy of the between. Second, I argue that the madman’s misconstrual of reality can be grasped as an idolatrous, divisive, and parodic imitation of the good. Third, I reflect on disembodied discernment. In some cases, due to the weakness of the moral (...) agent, the good cannot be properly embodied in space and time, even if a person exhibits ethically sound discernment. Fourth, I look at examples of holy discernment and examine how, through love, the genuinely good person is able to transform idolatry into a universal and cosmic sacramentalism. (shrink)

The identity and diversity of individual objects may be grounded or ungrounded, and intrinsic or contextual. Intrinsic individuation can be grounded in haecceities, or absolute discernibility. Contextual individuation can be grounded in relations, but this is compatible with absolute, relative or weak discernibility. Contextual individuation is compatible with the denial of haecceitism, and this is more harmonious with science. Structuralism implies contextual individuation. In mathematics contextual individuation is in general primitive. In physics contextual individuation may be grounded (...) in relations via weak discernibility. (shrink)

This paper critically discusses recent objections that have been raised against the contextual understanding of fundamental physical objects advocated by non-eliminative ontic structural realism. One of these recent objections claims that such a purely relational understanding of objects cannot account for there being a determinate number of them. A more general objection concerns a well-known circularity threat: relations presuppose the objects they relate and so cannot account for them. A similar circularity objection has also been raised within the framework of (...) the weak discernibility claims made in the last few years about quantum particles. We argue that these objections rely either on mere metaphysical prejudice or on confusing the logico-mathematical formalism within which a physical theory is formulated with the physical theory itself. Furthermore, we defend the motivations for taking numerical diversity as a primitive fact in this context. (shrink)

The significance of Max Black’s indistinguishable spheres for the nature of particles in quantum mechanics is discussed, focusing in particular on the use of the idea of weak indiscernibility. It is argued that there can be four such Black spheres but that five are impossible. It follows from this that Black’s example cannot serve as a model for indistinguishability in physics. But Black’s discussion of his spheres gave rise to the idea of weak discernibility and it is (...) argued that such predicates are unsatisfiable in the way intended. The underlying problem with weak discernibility spreads out to also undermine the whole notion that indistinguishability rests on a notion of the permutation invariance of particles. A better foundation is indicated. (shrink)

It is supposed that any scientific theory (here we consider physical theories only) has an underlying logic, even if it is not made explicit. The role of the underlying logic of a theory T is mainly to guide the proofs and the accepted consequences of the theory’s principles, usually described by its axioms. In this sense, the theorems of the underlying logic are also theorems of the theory. In most cases, if pressed, the scientist will say that the underlying logic (...) of most physical theories is classical logic or some fragment of a set theory suitable for accommodating the theory’s mathematical and logical concepts. We argue that no physical theory and no philosophical discussion on the basis of the theory should dismiss its underlying logic, so the arguments advanced by some philosophers of physics in that certain entities (the considered case deals with quantum entities) can be only weakly discerned or be just ‘relationals’ and that they cannot be absolutely identified by a monadic property, are fallacious if one remains within a ‘standard’ logico-mathematical framework, grounded on classical logic. We also discuss the claim that some properties (as those that came from logic) would be ‘illegitimate’ for discerning these entities is not justifiable. Thus, this paper may be interesting for logicians, physicists, and philosophers. (shrink)

The paper compares ontic structural realism in quantum physics with ontic structural realism about space–time. We contend that both quantum theory and general relativity theory support a common, contentful metaphysics of ontic structural realism. After recalling the main claim of ontic structural realism and its physical support, we point out that both in the domain of quantum theory and in the domain of general relativity theory, there are objects whose essential ways of being are certain relations so that these objects (...) do not possess an intrinsic identity. Nonetheless, the qualitative, physical nature of these relations is in the quantum case (entanglement) fundamentally different from the classical, metrical relations treated in general relativity theory.

An examination of the fundamental role cybernetics played in the birth of cognitive science and the light this sheds on current controversies. The conceptual history of cognitive science remains for the most part unwritten. In this groundbreaking book, Jean-Pierre Dupuy—one of the principal architects of cognitive science in France—provides an important chapter: the legacy of cybernetics. Contrary to popular belief, Dupuy argues, cybernetics represented not the anthropomorphization of the machine but the mechanization of the human. The founding fathers of cybernetics—some (...) of the greatest minds of the twentieth century, including John von Neumann, Norbert Wiener, Warren McCulloch, and Walter Pitts—intended to construct a materialist and mechanistic science of mental behavior that would make it possible at last to resolve the ancient philosophical problem of mind and matter. The importance of cybernetics to cognitive science, Dupuy argues, lies not in its daring conception of the human mind in terms of the functioning of a machine but in the way the strengths and weaknesses of the cybernetics approach can illuminate controversies that rage today—between cognitivists and connectionists, eliminative materialists and Wittgensteinians, functionalists and anti-reductionists. Dupuy brings to life the intellectual excitement that attended the birth of cognitive science sixty years ago. He separates the promise of cybernetic ideas from the disappointment that followed as cybernetics was rejected and consigned to intellectual oblivion. The mechanization of the mind has reemerged today as an all-encompassing paradigm in the convergence of nanotechnology, biotechnology, information technology, and cognitive science. The tensions, contradictions, paradoxes, and confusions Dupuy discerns in cybernetics offer a cautionary tale for future developments in cognitive science. (shrink)

In the Treatise,?,??,?, Hume presents an follows:' argument which, in the barest of outlines, goes as 1 (Pl) Every proposition has a probability less than one. (P2) If reason were the basis of our beliefs, then we would have no beliefs. (follows from (Pl)) (P3) We in fact do have beliefs. Hence, (P4) Reason is not the basis of our beliefs. The argument has (...) not been particularly well received. D. C. Stove, for example, refers to it as being "not merely defective, but one of the worst 2 arguments ever to impose itself on a man of genius." While not everyone is as unsympathetic as Stove, it nonetheless is difficult to find commentators favorably disposed toward the argument. Various sections of the Treatise are notoriously unclear.?,??,? is such a section; as such, it is difficult to say just what Hume intended his argument to be. My contention in the present paper is that there are two reasonable ways of reconstructing Hume's argument, both consistent with what Hume writes in?,??,?. The first reconstruction is clearly unsound; the second reconstruction fares somewhat better. In particular, my contention will be that this second reconstruction, if not sound, is at least valid 4 and contains no obviously false premises. Allow me to make some preliminary comments before presenting these reconstructions. The reconstructions to follow will primarily be concerned with premise (P2) above; in particular, the 126. reconstructions will focus on how Hume can claim that (P2) follows from (Pl). Premise (Pl) is a common 5 sceptical claim, not obviously false, and certainly not unique to Hume. As such, it strikes me that the more interesting part of the argument is Hume's claim that (P2) follows from (Pl), and such will be the focus of the reconstructions (although (Pl) will be discussed toward the end of this paper). Concerning (P2), why does Hume think this follows from (Pl)? His reasoning is contained in the following passage; Having thus found in every probability, beside the original uncertainty inherent in the subject, a new uncertainty deriv'd from the weakness of that faculty, which judges, and having adjusted these two together, we are oblig'd by our reason to add a new doubt deriv'd from the possibility of error in the estimation we make of the truth and fidelity of our faculties. This is a doubt, which immediately occurs to us, and of which, if we wou'd closely pursue our reason, we cannot avoid giving a decision. But this decision, tho' it shou'd be favourable to our preceeding judgment, being founded only on probability, must weaken still further our first evidence, and must itself be weaken'd by a fourth doubt of the same kind, and so on in infinitum; till at last there remain nothing of the original probability, however great we may suppose it to have been, and however small the diminution by every new uncertainty. No finite object can subsist under a decrease repeated in infinitum; and even the vastest quantity, which can enter into human imagination, must in this manner be reduc'd to nothing. (T182) Not for nothing did I claim that this section of the Treatise is unclear. At best, I can discern only the outline of Hume's reasoning, which seems to go as follows: first, when we assign a probability to some 127, proposition, reason dictates that we re-evaluate this probability. In particular, reason dictates that we "add a new doubt deriv'd from the possibility of error in the estimation we make of the truth and fidelity of our faculties." Note that Hume never specifies the object of this 'new doubt.' He might mean a) that our doubt concerns whether the probability we assigned the proposition is correct, or b) that our doubt concerns the evidence on which we based the assignment of that probability. Whatever the case, this 'new doubt' must "weaken still further our first evidence," presumably resulting in a lowering of the probability we originally assigned to the proposition. We then repeat this doubting process, adding new doubts of the same kind in infinitum, "till at last there remain nothing of the original... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Christian Moral Life: Faithful Discipleship for a Global Society by Patricia Lamoureux, Paul J. WadellVictor Lee AustinThe Christian Moral Life: Faithful Discipleship for a Global Society Patricia Lamoureux and Paul J. Wadell Maryknoll, NY: Orbis Books, 2010. 306pp. $27.00In ten chapters, the authors provide what is in effect an introductory college textbook in Roman Catholic moral theology. They aim to ground their exposition in scripture and to (...) reach a broad audience by drawing on ecumenical and interfaith perspectives. Their organization is clear: they summarize each chapter in advance and then conclude it with a list of main points and questions for reflection. The index is extensive, the bibliography is large, and the table of contents is quite detailed. In short, the book aims to be accessible to undergraduates and helpful to more advanced students. (There is, unfortunately, no index of scriptural citations.) [End Page 201]The arc of their approach to moral theology is as follows. One should begin with discipleship and more specifically with its dynamic of call and response. Discipleship is a process in which one learns to see, particularly to see the reign of God. Sin and repentance are continually involved in discipleship. The development of the virtues is central because through them we learn to be good at being human. In the moral life, conscience is the central gift by which we learn to live by love in a Eucharistic life. Such life is informed by the resurrection as understood both “analogically and dialectically” (206), it is guided by the Spirit, and it is anchored in the shared resources and discernment of Christian community. Finally, the moral life is not private. Thus, the authors conclude with a chapter that draws out the implications for public discipleship.I venture three critiques that arise in part from my place as an Anglican moral theologian. The first deals with scripture. The authors are aware of the characteristic biases of preconciliar Roman Catholic moral theology. I am less certain that they are self-conscious of some of their own presuppositions. Commendably, they provide a verse of scripture at the head of each chapter, and they conceive of what they are doing as working from scripture throughout. Yet it is not clear to me that they present us with a moral theology that comes out of a prayerful wrestling with scripture. For example, their statement, “Jesus praises the [good] Samaritan” (46) is not strictly true. Rather, in telling that parable, Jesus holds back from stating a conclusion. Moreover, the authors are correct to say that parables are useful in transforming our vision. They make that point over eight pages (39–47), in which there are seventeen citations of secondary literature from six different authors. Yet, I would have preferred to see how the authors themselves digested, synthesized, and struggled with the parables, rather than simply discussing the conclusions of others.My second critique deals with conscience. When students start to think about how the moral life is grounded in scripture, they will at some point ask: What if my conscience tells me that something is right that scripture says is wrong (or vice versa)? This question, however, does not appear in this book. In their chapter on the centrality of conscience, it becomes clear that the authors see the primary challenge to the primacy of the conscience as coming from “church leaders.” This is, I think, a regrettable continuation of the tired struggle of Roman moral theologians with their church’s magisterium. At least to this outsider—who lives within an ecclesial context marked by extreme weakness of teaching—there seems to be a highly important and positive use of obedience, which is different from the “mystique of obedience” that these authors criticize (170–71). To be precise, “church leaders” can help us learn something about the relationship of conscience and scripture. This book does not show the place of obedience in the Christian moral life.My last point is a comment on textbooks. Although this book is quite long (I estimate it at 150,000 words), it has that textbook quality of passing lightly [End Page 202] from one thing to the next... (shrink)

Medical decisions for children are usually justified by the claim that they are in a child's best interests. More recently, following criticisms of the best interests standard, some advocate that the family's interests should influence medical decisions for children, although what is meant by family interests is often not made clear. I argue that at least two senses of family interests may be discerned. There is a ‘weak’ sense of family interests and a ‘strong’ sense. I contend that there (...) are problems with both approaches in making medical decisions for children but that the weak sense is more plausible. Despite this, I argue that claims for family interests are not helpful in making medical decisions for children. (shrink)

This paper examines the recent rise of initiatives for responsible agricultural investment and provides a preliminary assessment of their likely success in curbing the ecological and social costs associated with the growth in private financial investment in the sector over the past decade. I argue that voluntary responsible investment initiatives for agriculture are likely to face similar weaknesses to those experienced in responsible investment initiatives more generally. These include vague and difficult to enforce guidelines, low participation rates, an uneven business (...) case, and confusion arising from multiple and competing initiatives. In addition, the large diversity of investors and high degree of complexity of financial investments further complicate efforts to discern who bears the burden of responsibility in practice. As a result, there is a strong likelihood that voluntary governance initiatives for responsible agricultural investment will shift discourse more than they will change practice. (shrink)

Constructive set theory started with Myhill's seminal 1975 article [8].

Are people at bottom motivated entirely by self-interest? Or do they act only sometimes out of self-interest, and sometimes for other reasons—say, to help out a friend for her own sake, with no expectation of being benefitted in return? Scholars have often thought they could discern in the works of classical Greek thinkers a commitment to psychological egoism, the thesis that one is motivated to act only by considerations of the expected benefits and harms that will accrue to oneself. For (...) instance, a host of influential interpreters have taken Plato to be wedded to psychological egoism throughout his corpus. Often, the commitment is thought to run so deep that Plato rarely, if ever, manages to articulate it explicitly, let alone to examine it critically and defend it. That kind of approach obviously invites challenges, and lately there has been a small but growing resistance to the egoistic interpretation of Plato. The challenges are especially welcome given the general lack of support for psychological egoism in the present intellectual climate: egoistic readings have increasingly seemed to imply a crippling weakness in the Platonic system.

This study discusses the treatise of Jalāl al-Dīn Davvānī (d. 908/1502) named Risāla fī taʻrīf ʻilm. This treatise criticizes a definition of knowledge adopted by some theologians in the late period (mutaʾakhkhirīn). The definition of knowledge at issue consists of three components: Attribution, discernment, no possibility of contradiction. Knowledge is an attribute as a category and with this attribution, a discernment is obtained. As a result of this process knowledge is acquired and there should be no possibility of this knowledge (...) to be inconsistent. Davvānī examines eight possibilities of the definition on knowledge. In each of these eight possibilities a different problems arises. According to Davvānī, the definition mentioned is problematic in all probability. Nonetheless, Davvānī does not propose another definition of knowledge that can replace the definition of knowledge that he criticizes. This article represents the process of reaching the definition of knowledge stated in the history of theological thought. The definitions on knowledge made from the first period (al-mutaqaddimīn) are summarized and the strengths and weaknesses of these definitions are explained. There are two main approaches regarding the nature of knowledge in Islamic thought: According to the first approach pioneered by Fakhr al-Dīn Rāzī (d. 606/1202), absolute knowledge is a priory (badīhī) and undefinable. According to the second one, the nature of absolute knowledge is a posteriori (naẓarī) and definable. The first part of this article includes the definitions and criticisms of knowledge in Islamic thought. The second part discusses the claim of originality. In the second part, Davvānī’s treatise will be evaluated for the first time. According to the conclusion of the treatise, the definition made to find the essence of knowledge is unfounded in all respect. It is important to evaluate the treatise as a reflection of anti-essentialism in the history of Islamic thought. Most contemporary studies do not count this treatise among Davvānī’s works. In the biography book al-Aʿlām written by Khayr al-Dīn al-Ziriklī (d. 1976), Risāla fī taʻrīf ʻilm is counted among the works of Davvānī. In the introduction of more than one manuscript, the work is clearly attributed to Davvānī. As a result of the double-sided research, it has been ensured that the work belongs to Davvānī. However, in other two manuscripts containing the same treatise, the work is shown as belonging to an unknown person named Şāirzāda. But there is no information found about this person. This name seems more like a copyist (mustansıh) than an author. Possibly, such a mistake occurred as a result of confusing the two names. Davvānī’s small volume treatise sheds light on the intellectual atmosphere and level of its period. The definition of knowledge mentioned in the classical theology book of ‘Aḍud al-Dīn al-Ījī (d. 756/1355) called al-Mawāqif is superior to other definitions of knowledge. Instead of this definition of knowledge, which is presented as perfect, Jurjānī (d. 816/1413) preferred the definition of knowledge attributed to al-Māturīdī (d. 333/944) in the Sharḥ al-Mawāqif. This preference has been accepted as an implicit criticism for future generations, including Davvānī. Those who claimed that Jurjānī did not taken a random choice, carried on their criticism by going over the definition. The fine craftsmanship revealed in the treatise reveals that critical thinking is used intensively. The properly understanding of the treatise depends on knowing the science of logic and following it with intense attention. The definition of knowledge is examined from various angles with the help of concepts such as conception, ratification, judgment and contradiction (nakz) of the science of logic. In the science of logic, every layer of knowledge such as certainty, conjecture, imitation, doubt is investigated one by one. In the science of kalām, attention is paid that the ideal level of knowledge is precise. An uncertain knowledge is not considered knowledge according to kalām. Because the main goal of theologians is to build religious beliefs on the obtained certain knowledge. It is not accepted to base knowledge to a probable information on imprecise knowledge. For a knowledge among the knowns to reach the level of certainty, it must be correct and exclude other possibilities. Another condition is required for certainty in the definition of knowledge that Davvānī examines in his treatise is that the opposite is wrong. The fact that a piece of information is considered true depends on the fact that its reverse is false. In this treatise, it is discussed how to look for the contradictions or discrepancy that are wanted to be excluded. Knowledge is inseparable from the human mind, from outside of the world, or from the relationship between the two. (shrink)

The text of “The Four Premises” (Muqaddimāt al-Arba‘a), which began with Sadr al-Sharī‘ah (d. 747/1346), centralizes on the actions of human beings by connecting it with the problem of good and evil in the field of kalām, Islamic philosophy and logic, and fıqh. It was also commented in with incisive and critical footness by Sa‘d al-Dīn al-Taftāzānī (d. 791/1390). In Ĥāshiya ‘alā Muqaddimāt al-Arba‘a, al-Kastalī (d. 901/1496) discusses the two main issues. One of them is good/husn-evil/qubh, the other is human (...) actions. Good-evil dichotomy here is axiological, whereas the human actions are examined within an ontological structure. The quest for the origin of moral values is a husn-qubh debate. Identifying the hierarchy of human actions in ontology is another problem. The main purpose of this study is to investigate the theological discussions in the Ĥāshiya ‘alā Muqaddimāt al-Arba‘a which were written following the order of Sultan Mehmed the Conqueror/Fatih. This text addresses the origin of moral judgment and the question of freedom and destiny in human actions linked to the problem of good and evil. Discussing these two fundamental issues, has made it necessary to thoroughly investigate perhaps all the subheadings which concern the entire paradigm that falls under the framework of understanding the God, nature, and humanity. By looking at the treatise, the main sources of the issues being discussed are mostly generated from an Islamic jurisprudence works, entitled Tawḍīḥ and Talwīḥ. It can easily be discerned that the direct quotations that were made or taken indirectly were from these two sources. References to other sources were quite seldom. However, the excerpts that were taken from primary sources were interpreted and expounded by the author and amended anew. In this article al-Kastalī’s comments will be analyzed. He’s work Ĥāshiya ‘alā Muqaddimāt al-Arba‘a will be analyzed in depth and will be published for the first time with a critical edition. Text of Muqaddimāt al-Arba‘a is a product of a culture of criticism and critical thinking has two foundations: Disproval and verification. Critical thinking is then bidirectional. It is wrong to carry out the criticism activity in only one direction. It is insufficient to simply refute the opposing idea. It is not enough to show the wrong. The so-called right idea also needs to be justified. In the Tawdīh, Sadr al-Sharī‘ah criticizes al-Ashʿarī in the issues of husn-qubh and human actions. According to this criticism, good and evil should be based on the reason. On the other hand, human is free in his actions. As it is known, goodness and badness was based on religion according to al-Ashʿarī. Acquisition (kasb) given to man was unclear. It is al-Taftāzānī who wrote an annotation on Tawḍīḥ with the name of Talwīḥ. He’s comments are successful in terms of theology. However, these interpretations do not mean that he accepted the Muqaddimāt al-Arba‘a. In terms of al-Taftāzānī, proofs of Sadr al-Sharī‘ah is weak. The theological disputes in Tawḍīḥ and Talwīḥ have reached the level of tension in the following works. The origins of the divergence are based on the differentiation between the schools of al-Māturīdi and al-Ashʿarī. In fact, these schools are not different from each other in terms of the method they use. Although the roads walked were the same, the results achieved were different. The main reason for this is that the issue is ambiguous and the problem of good and evil is multidimensional. It is directly related to God and human. It is also connected with ontology and epistemology together. The position on the husn-qubh issue is also decisive for other theological problems. The root of the evil problem or theodicy is mostly based on this problem in Islamic thought. The actions of God and human are questioned here. The value judgments that actions will take are examined. Which action is more moral and better? Another major problem discussed in this article is human actions. It is a matter of freedom of human volition. The volition of man before the absolute God is a problem. Because God has absolute power, will and knowledge. On the other hand, God imposes responsibility on man. But what are the limits of this responsibility? Al-Kastalī discusses all these problems in the context of Sadr al-Sharī‘ah and al-Taftāzānī. In the big picture there are representatives of the schools of al-Māturīdi and al-Ashʿarī. Al-Kastalī doesn’t paint a new picture, rather makes the lines in the picture clear. In this article, the texts will be analyzed mutually. The content and uses of the concepts will be given importance. Ideas will be discussed from their main sources and the roots and different reach of the issues will be touched. The interactions of different schools of thought will also be included. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 29, Number 2, November 2003, pp. 267-282 Skepticism and Philo's Atheistic Preference DAVID O'CONNOR [H]owever consistent the world may be... with the idea of... a very powerful, wise, and benevolent Deity... it can never afford us an inference concerning his existence. The consistence is not absolutely denied, only the inference.1 The whole presents nothing but the idea of a blind nature, impregnated by a great vivifying (...) principle, and pouring forth from her lap, without discernment or parental care, her maimed and abortive children. (DNR, 211) The true conclusion is, that the original source of all things is entirely indifferent to all these principles, and has no more regard to good above ill than to heat above cold, or to drought above moisture, or to light above heavy. (DNR, 212) There may four hypotheses be framed concerning the first causes of the universe: that they are endowed with perfect goodness, that they have perfect malice, that they are opposite and have both goodness and malice, that they have neither goodness nor malice.... The fourth... seems by far the most probable. (DNR, 212) David O'Connor is Professor of Philosophy, Seton Hall University, South Orange, New Jersey 07079. e-mail: [email protected] 268 David O'Connor What I have said concerning natural evil will apply to moral, with little or no variation; and we have no more reason to infer, that the rectitude of the supreme Being resembles human rectitude than that his benevolence resembles the human. Nay, it will be thought, that we have still greater cause to exclude from him moral sentiments, such as we feel them; since moral evil, in the opinion of many, is much more predominant above moral good than natural evil above natural good. (DNR, 212) Thus Philo in part 11 of Hume's Dialogues concerning Natural Religion. I In the first of these passages, Philo is denying that the existence of "a very powerful, wise, and benevolent Deity" can justifiably be inferred from the facts of good and evil present to our experience. But power, wisdom, and benevolence are essential qualities of the God of traditional theism, thus Philo is here denying that the existence of such a being can justifiably be inferred from the empirical evidence of good and evil. The other passages show us Philo going further than this, indeed all the way to what seems to be a preference for moral atheism. The term is J. C. A. Gaskin's, and he defines it thus: "[moral atheism] will be [the position of] anyone who denies the existence of any god having moral attributes."2 In the second and third passages specifically, this prima facie preference is absolute ("[t]he whole presents nothing but the idea of a blind nature... without discernment" and "the original source of all things is entirely indifferent," respectively), while it is relative and more cautiously expressed in the fourth passage. And the fifth passage says at least as much as the first and perhaps as much as the second and third. Yet Philo very early in the book declares himself a skeptic on such metaphysical topics as "the origin of worlds" (DNR, 132), "the existence and properties of spirits" (DNR, 135), "the powers and operations of one universal spirit, existing without beginning and without end; omnipotent, omniscient, immutable, infinite" (DNR, 135). The principal reason he gives is the "weakness, blindness, and narrow limits of human reason... even in subjects of common life and practice" (DNR, 131). Considering these limits, surely it is very likely that "we have... got quite beyond the reach of our faculties" (DNR, 135) if and when we turn to such metaphysical topics as those he just listed. On these matters, which "run wide of common life... [t]he mind must remain in suspense... and it is that very suspense or balance, which is the triumph of skepticism" (DNR, 135-6).

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Karl Barth and Christian Ethics: Living in Truth by William WerpehowskiJames W. SkillenKarl Barth and Christian Ethics: Living in Truth William Werpehowski BURLINGTON, VT: ASHGATE, 2014. 172 PP. $54.95 (PAPERBACK), $153.00 (CLOTH)In this two-part volume, William Werpehowski aims in part 1 to elucidate Karl Barth's "approach to the nature and source of the good, the divine command in its relation to the personal history of a moral agent, (...) and the place of narrative in Christian ethics" (xii). The author does this both by exposition of Barth's writings and by engaging with the arguments of other students of Barth, including James Gustafson, Stanley Hauerwas, John Webster, Matthew Rose, and Gerald McKenny. The titles of the chapters of part 1 indicate the ground being covered: "Divine Commands and Philosophical Dilemmas," "Command and History," "Narrative and Ethics," and "Realism and Discernment." In part 2 the author presents diverse essays on "virtue, moral practices, and discernment," most of which deal with the rearing and education of children, which shows the author's sympathy with Barth even as he draws on other traditions of Christian ethics.Werpehowski's exposition is generally clear and detailed as he seeks to explain and defend Barth's identification of the norm for human ethics with the subject, Jesus Christ. According to Barth, "humanity's obedience to God … must always be obedience to and conformity with Jesus Christ. He is the criterion by which is measured all demands on our behavior" (6). Furthermore, "God's eternal will is for humanity in Jesus Christ; the normative criterion is identical to God's will and the history it accomplishes" (7). Although the response to God's electing love in Christ should be willing obedience, Barth (with Werpehowski) does not deal substantively with the accountability of those who do not so respond. In the end, for Barth, God's "Yes" in Christ always trumps God's "No" to sin (see 65–69).At times the author's defense of Barth appears to be more a deflection of, than an engagement with, the criticism. One example: the author offers a brief summary of Nigel Biggar's sympathetic criticism of Barth at the point where he believes Barth deals inadequately with human responsibility and accountability. Werpehowski acknowledges the legitimacy of Biggar's point—"that the temporal world of eternal grace may be depicted as our one common world only if creaturely rationality and non-arbitrary moral justification are prominently affirmed" (63); he states that Biggar is trying to save Barth "at his best" from a weakness in his position. Yet Werpehowski's next step is to say that Biggar's correction "is in danger of being an overcorrection" because his [End Page 212] moral justification requirement "belongs more to the periphery of the ethics of [Barth's] divine command" (64). That requirement, says Werpehowski, "must be governed by the central significance of the gracious God who commands in the reality of the ethical event" (64).Werpehowski's book is worthy of careful study, especially by those who want to understand Barth in relation to other ethicists. A criticism I have concerns the limits of Barth's ethics with respect to human institutions and social practices for which humans bear communal responsibility. Werpehowski acknowledges that those limits are due to Barth's focus on the relation of Christ to the individual person in the "ethical event." By contrast, at a few points in part 2, Werpehowski draws in Dietrich Bonhoeffer, who insists that it is in "friendships, families, work, citizenship, and life in the church" where Christ is present preserving and reconciling the world to God (141). Despite all the attention in recent decades to Christian social and political ethics, the author does little with that subject in either his assessment of Barth or in the chapters of part 2.James W.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:An Ethical Life: A Practical Guide to Ethical Reasoning by Richard KyteChristine FletcherAn Ethical Life: A Practical Guide to Ethical Reasoning Richard Kyte WINONA, NM: ANSELM ACADEMIC, 2012. 254 PP. $25.95Richard Kyte's introductory guide to ethics is designed to meet three concerns about current ethics textbooks: they tend to decrease students' confidence in their ability to think, they inculcate a distrust of deliberative processes, and they create an (...) appearance of moral relativism. Kyte succeeds in creating a text that overcomes these deficiencies. He uses common language and examples while remaining rigorous and fully explaining the common ethical theories.He opens with a chapter debunking thirteen misconceptions about ethics, such as "Ethics Is 'Nothing but Words,'" "Ethics Is Just a Matter of Opinion," and "Ethics Is Separate from Religion." This chapter should set the tone for a class that doesn't allow sloppy thinking or the reduction of ethics to feelings. The chapter concludes by defining ethics as common sense, meaning "the ability to find shared meaning in the words we use together to make sense of our lives" (51).The second chapter examines four ways of ethical thinking: truth, thinking in terms of the facts of the situation; consequences, thinking in terms of the results of an action; fairness, thinking in terms of equality and consistency; and character, thinking in terms of people's motivations, character traits, or both. He then uses practical problems to illustrate how, by using these four ways of ethical thinking, a conversation working toward an agreed-on action can take place. Ethics is no longer a shouting match but a way of appreciating different points of view and coming to a reasoned conclusion.The following chapters explore these four ways of ethical thinking. Chapter 3, "Truth," on its own would be an excellent text for any course that has "critical thinking" as a learning outcome. He covers moral responsibility, bias, self-deception, and power with succinct but powerful illustrations from life. He then moves on to discernment, which includes a discussion of good reading, evaluating sources of information, and evaluating arguments, including examples of the most common fallacies. His examples are from diverse sources such as Mark Twain's Life on the Mississippi, E. M. Forster's A Passage to India, the Bible, Francis Bacon, and situations in ordinary life. This gives richness to the text and presents these concepts in an accessible and interesting way.The next three chapters, "Consequences," "Fairness," and "Character," cover the main features of utilitarianism, deontological ethics, and virtue ethics [End Page 191] in good detail, with summaries about major figures associated with these theories: Jeremy Bentham, John Stuart Mill, Epictetus, Immanuel Kant, Aristotle, and St. Thomas Aquinas. These give the students biographical information as well as the significance of each thinker's work, explaining the key features, strengths, and weaknesses of their theories. The chapter on character has a very helpful discussion of the cardinal and theological virtues. Each chapter has suggestions for further reading.The appendix covers how to use this four-way method in group decision-making and in writing case studies or issues analyses, helpfully including an example of each. This book is written by a gifted teacher who draws students into his subject, shows them its relevance, and helps them develop the confidence and skills they need to take their part in the ethical conversations that will occur throughout their lives. It is an excellent text on its own or as a supplement to a standard textbook in professional ethics.Christine FletcherBenedictine UniversityCopyright © 2017 Society of Christian Ethics... (shrink)

The long standing reign of psychology as the privileged partner of education has, arguably, now been superseded by the neurosciences. Given that this helped to drive the emergent field of neuroeducation, it is crucial to ask what changes in education, if anything does in fact change, when the hitherto hegemonic psychologising discourse is substituted for a neurological one. The primary contention of this paper is that with the neuro-turn a process of “neurologisation” has also been initiated, which can be analysed (...) by taking into account its genealogical predecessor, psychologisation. In doing so, I argue, one ultimately discerns a primordial incompatibility between education and neuroscience, one that can be traced back to the fundamental and problematic reflexivity of modern subjectivity itself, which the discipline of psychology was never able to wholly resolve. From here, I proceed with the argument that while the eagerness of the psy-sciences to embrace neuroscience testifies to how much psychology needs neurology, the neurosciences are structurally incapable of disconnecting from the paradigms of the psy-sciences. Following on from this proposition, other strong/weak factors are brought into the equation: strong/weak nature, strong/weak culture, strong/weak subjectivity and, most pertinently, strong/weak education. Finally, the critical question becomes: if education in itself needs to take recourse to both the psy-sciences and the neurosciences, then how can we begin to account for the fact that these sciences invariably end up becoming captured within educational discourses themselves; that is, the fact that teachers, parents, and pupils themselves are taught the key insights of neuropsychology.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 719 An Apology for Apologetics: A Study in the Logic of lnterreligious Dialogue. By PAUL J. GRIFFITHS. New York: Orbis, 1991. ISBN: 0 88344 761 4. pp. 113. Jesus Christ at the Encounter of World Religions. By J. DUPUIS. New York: Orbis, 1991 (ET: Robert R. Barr, from French, 1989). ISBN: 0 88344 723 1. pp. 301. Griffiths presents a rigorous argument for the possibility of con· (...) tradictory claims between different religious communities. His inspira· tion, as he acknowledges, is William Christian Snr. His basic argu· ment is: " If representative intellectuals belonging to some specific religious community come to judge at a particular time that some or all of their own doctrine-expressing sentences are incompatible with some alien religious claim(s), then they should feel obliged to engage in both positive and negative apologetics vis-a-vis these alien religious claim(s) and their promulgators" (3). He takes negative apologetics to be a critique of arguments made against one's own religious claims, showing that such arguments fail or are inconsistent or incoherent. Positive apologetics shows how a particular religious community's doctrines are cognitively superior, in some respect(s), to another religious community 's doctrines. It is essential for this enterprise that only methods of argumentation and criteria of knowledge acceptable to the adversary are employed. This requires the acceptance of natural theology. Griffiths is well aware of the lion's den he is entering, as his proposals run counter to much scholarship in the area of interreligious dialogue, so he spends three chapters apologetically tackling the lions. The objectors (who mainly remain in notes) include Derrida, Barthes, Winch, Lindbeck, Hick, Huxley, Nasr, Plantinga and others, although Mac· Intyre is curiously missing. This technique has the advantage of isolating and presenting arguments, without falling into problems of cor· rect exegesis of opponents. And this is also its weakness, as objectors will sometimes feel caricatured or misunderstood-as is surely the case with Plantinga and in one instance, Hick. First, he tackles objections that sentences from one tradition are either incomprehensible or incommensurable with those of another, convincingly showing that the strong versions of both claims are self· defeating and unsustainable. Weaker versions still allow for his proj· ect-or so he thinks. This is where Maclntyre's work should have been considered. Then he tackles various theories of religious language (following Lindbeck's typology). He argues against non-cognitive accounts that reduce beliefs to the credibility of causes for holding beliefs, a position incapable of asserting its truth over other views because of its 720 BOOK REVIEWS own presuppositions. He follows Lindbeck in criticizing experiental expressivism, and then turns upon Lindbeck's own form of rule theory (which is ambivalent regarding cognitive claims), arguing convincingly that to suggest that only sentences uttered confessionally and with performative function can possess ontological truth is confused (42). In a brief review it is not possible to rehearse Griffiths's careful argumentation. Griffiths then sets about tackling two types of universalists: Hick and Huxley. Of Hick, he argues that some criteria are required to discern true from false religions (e.g. Jim Jones) and in so doing such a position needs to support and develop such criteria, thereby effectively introducing apologetics. He neglects to deal with Hick's pragmatic criteria of beneficial ' fruits ' evident in adherents, but the logic of his argument can be applied to Hick's proposals. Using Katz and Zaehner, he argues against the esoteric universalism of the philosophia perennis. (The arguments of Robert Forman's recent book, The Problems of Pure Consciousness, are strangely neglected, despite Griffiths's being a contributor to that collection.) Finally, he tackles objections against positive apologetics-first, on the grounds that it has a negative effect on interreligious relations. Logically, this need not be the case, although Griffiths is well aware that the political context of apologetics can obscure its proper goal: deeper critical understanding, learning and problem solving. Then, in sustained dialogue with Plantinga, he argues against the objection that success is impossible. It is impossible only if " knockdown drag-out" (64) argumentative victory is expected. Griffiths suggests the cumulative -case argument and gives instances of such successful apologetics (medieval... (shrink)

The conceptual history of cognitive science remains for the most part unwritten. In this groundbreaking book, Jean-Pierre Dupuy--one of the principal architects of cognitive science in France--provides an important chapter: the legacy of cybernetics. Contrary to popular belief, Dupuy argues, cybernetics represented not the anthropomorphization of the machine but the mechanization of the human. The founding fathers of cybernetics--some of the greatest minds of the twentieth century, including John von Neumann, Norbert Wiener, Warren McCulloch, and Walter Pitts--intended to construct a (...) materialist and mechanistic science of mental behavior that would make it possible at last to resolve the ancient philosophical problem of mind and matter. The importance of cybernetics to cognitive science, Dupuy argues, lies not in its daring conception of the human mind in terms of the functioning of a machine but in the way the strengths and weaknesses of the cybernetics approach can illuminate controversies that rage today--between cognitivists and connectionists, eliminative materialists and Wittgensteinians, functionalists and anti-reductionists. Dupuy brings to life the intellectual excitement that attended the birth of cognitive science sixty years ago. He separates the promise of cybernetic ideas from the disappointment that followed as cybernetics was rejected and consigned to intellectual oblivion. The mechanization of the mind has reemerged today as an all-encompassing paradigm in the convergence of nanotechnology, biotechnology, information technology, and cognitive science. The tensions, contradictions, paradoxes, and confusions Dupuy discerns in cybernetics offer a cautionary tale for future developments in cognitive science. (shrink)

While the Triple Helix and Quadruple Helix models are popular in innovation studies, the relations between them have not been addressed extensively in the literature. There are diverse interpretations of helix models in empirical studies that apply them, but these sometimes deviate from the original theses of the models. Such a situation can confuse newcomers to the field in terms of which helix model to apply in their empirical research. We discern that the cause of this research challenge is a (...) lack of systematic comparison of the two models. To bridge the research gap, this paper compares the models from the perspectives of how they were introduced and discussed in the literature and improved and how useful they are in addressing the innovation processes in contemporary society. Our major findings are as follows: First, reviewing the extant literature applying the two helix models for identifying research gaps, we discover that these studies were influenced by three views on the relations between the two models that were located on a continuum between two extreme ends—namely, isolation versus integration of the two models. Second, we provide a systematic comparison of both the advantages and weaknesses of the two models, and this may help researchers choose suitable helix models as conceptual/analytical tools in their empirical innovation studies. Third, our comparison of the two models shows that they are largely supplementary to each other when analysing innovation processes in contemporary society, providing a ground for potential synergy building between the two helix models.

The agro-pastoral ecotone, an ecological transition zone connecting adjacent areas of agricultural planting area and grassland animal husbandry, has three features: a complex natural condition, relatively pronounced population pressure, and a fragile ecological environment. In this study, we conducted an ecosystem risk assessment in the western part of Jilin Province, China, based on multiscale and multitemporal remote sensing images and land-use data. Furthermore, we focused on land-use change from 1995 to 2015 by applying the dynamic change information survey method and (...) carrying out a transfer track analysis. The results revealed three main findings. The ecological risk index at the scale of 3 km × 3 km harbors significant spatial correlation. The ecological risk index of unutilized land, forest land, and grassland is relatively high for each, and their anti-interference ability is weak, while the ecological risk index of construction land and water area is the lowest. Human interference, e.g., construction activities and cultivated land occupation, is the leading factor driving the exacerbation of ecological risk and frequent land-use type conversions. At the study period’s end, a trend of slight contraction in the high-risk areas was found, indicating that land-use regulation and land protection policies have had significantly positive impact upon the lands’ ecological value. The overall study identified a reasonable research scale for eco-environmental risk assessment and discerned relationships between regional land-use changes through geospatial analysis. Moreover, our findings can help provide practical case study information applicable to similar regions with agro-pastoral ecotones. (shrink)

Internet-based religious learning has presented a new face to the diversity of Muslim youth. This article aims to analyse and evaluate Muslim youth’s understanding, attitudes, and religious practices and demonstrate the impact of internet-based Islamic learning. As many as 23 Muslim youths in Jepara, Central Java, aged 17–20 years, became the informants of this study. Data were collected through in-depth interviews and observations. Further research data were analysed descriptively and interpretatively. This study found that most Muslim youths who studied Islam (...) online experienced confusion and emptiness in religion caused by an incomplete learning process. Most Muslim youths do not have solid theological views, pseudo-worship practices and weak religious ideologies. This study suggests that teenagers acquire essential Islamic knowledge from credible sources such as kyai with clear scientific credentials. This foundation enables them to discern reliable Islamic content in cyberspace, safeguarding against distortions in their understanding of Islam and spirituality.Contribution: This research provides a more comprehensive understanding of the complexities of the impact of internet-based learning on the diverse experiences of Muslim youth. Although the internet has the potential to be an invaluable source of knowledge, the challenges of integrating information with traditional understanding require serious attention. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 145 Luther on Thomas Aquinas: The Angelic Doctor in the Thought of the Reformer. By DENIS R. JANZ. Veroffentlichungen des Instituts fiir Europiiische Geschichte Mainz, Abt. Religionsgeschichte, Bd. 140. Stuttgart: Franz Steiner Verlag, 1989. Pp. ii + 124. DM 38 {cloth). As Denis Janz, specialist in the late medieval context of Luther's thought (Luther and Late Medieval Thomism, 1983), points out in the "Prospectus," a study of (...) Luther's understanding of Thomas has an inherent appeal, for, " rightly or wrongly, Thomas and Luther are inevitably regarded as the standard-bearers of Roman Catholicism and Protestantism" {p. 1). The recent completion of the necessary critical indices has made the task possible, and the result is a fine and necessary contribution to the work of all scholars interested in the thought of these two pivotal Christian thinkers. The method of Janz is straightforward: assemble the references to Thomas in Luther's works, organize them into appropriate categories, exegete their meanings, and discern important tendencies or perspectives common to these texts. Then "the accuracy of Luther's understanding and the cogency of his critique " can be evaluated from the perspective of twentieth cenrtury historical knowledge {p. 2). Janz recognizes that there are significant hermeneutical difficulties inherent in such a study and that any evaluation " may well imply a notion of history as progress, perhaps even a confidence in the intellectual superiority of modernity over the past " (p. 3). The result bears out the soundness of his approach. Chapter I examines "Luther on the Person of Thomas." Luther, sharing in and contributing to his time's distinctive theological polemic, had no shortage of epithets for Thomas, from " Sophist " to " beggarly paunch " {p. 4). The remarkable thing is the surprising number of complimentary things he has to say. At different times of his career Luther referred to Thomas as " this holy man " or " a man of ' great genius '... woefully misunderstood " {p. 5). A most interesting example is the different uses he makes of a story of Thomas's struggle with despair when near death, when Thomas faced his Anfechtung by holding the Bible and saying "I believe what is in this book" (p. 8). Sometimes Luther cites it as an example of the weakness of implicit faith; but other times he makes no critical comment on Thomas, and the story implies the victory of faith over despair. These different uses show the ambiguity of Luther's attitude toward Thomas as a person, and what in balance seems to be " grudging respect " for an " example of how great persons can at the same time be seriously mistaken " (p. 10). 146 BOOK REVIEWS Chapter U, which comprises the bulk of the hook, carefully examines the substantive issues on which Luther mentions and responds to Thomas: experience, the use of Aristotle, Scripture, penance and indulgences, the Lord's Supper, monasticism, justification, law, baptism, angels, papal authority, purgatory, and the veneration of images. On some of these issues Janz sees only a minor critique of Thomas by Luther and sometimes little real difference between their positions. Both Luther and Thomas give primacy to the literal sense of Scripture, and "both teach that the Church and theology stand under the authority of Scripture" (p. 30). On this question Luther's critique has more to do with the Thomists than Thomas. In regard to penance and indulgences Luther criticizes Thomas's view, though here again there is distortion of Thomas by the Thomists, which Luther correctly suspects (pp. 44-45). Though Luther disagrees with Thomas's understanding of the Lord's Supper, he feels Thomas was entitled to his opinion; what he cannot bear is how Thomas has been raised " to the level of an infallible teacher," with his opinions transformed "into articles of faith" (p. 48). Justification, the heart of Luther's thought, is "a relatively insignificant issue " in his critique of Thomas, as Luther eventually comes to understand better the key place Thomas gave grace (pp. 60, 61). Luther sees Christ as the " abrogation " of the law and criticizes Thomas for not seeing it this way; however, this is a linguistic misunderstanding of Thomas, probably based on Gabriel Bicl's teaching, so that Thomas and Luther are...

In this essay, I aim to defend Spinoza against Hegel’s claim that he annihilated finite things and the real differences they instantiate. To counter Hegel’s charge of acosmism, I try to conceive of a Spinozist kind of acosmism that would mean not a metaphysical eliminativism or nihilism about finitude and diversity, but rather a metaphysical fictionalism about finitude that entails a latent application of the principle of the discernibility of identicals. I do this by focusing on the correspondence between (...) Spinoza’s three kinds of knowledge – imagination, intellection, and intuition – and his understanding of things as being finite, infinite in kind, and absolutely infinite. In the process, I also entertain Yitzhak Melamed’s argument that Hegel was wrong to accuse Spinoza of acosmism, but was onto something by noting the lack of full or self-subsistent existence on the part of finite modes. Melamed offers a reading that claims Spinozist individuals are weak and functional properties that follow from God as his effects. I respond that Melamed would be correct only if we view things from the perspective of the first kind of knowledge, which is a perspective that is by definition false. I conclude, then, that finite things in Spinoza, qua finite, are not illusions, but fictions, and that when viewed truly or truthfully they are so many infinite in kind or absolutely infinite ways one infinite and eternal substance, God or nature, is discernibly identical to itself.

In 'Non-Anthropocentrism? A Killing Objection', Tony Lynch and David Wells argue that any attempt to develop a non-anthropocentric morality must invariably slide back to either anthropocentrism (either weak or strong) or a highly repugnant misanthropy in cases of direct conflict between the survival needs of humans and nonhuman species. This reply argues that their attempt to expose the flaws in non-anthropocentrism deflects attention away from the crux of the ecocentric critique, which can best be understood if we replace the (...) confusing terms anthropocentrism/non-anthropocentrism with 'human racism'/ecocentrism (understood as a more inclusive moral perspective which encompasses nonracist humanism). Human racism manifests when a reconciliation of human and nonhuman needs is possible but is nonetheless concealed and/or denied. That is, the best test for discerning prejudice against nonhuman nature is not when individual or social choice are severely circum-scribed but rather when such choices are relatively unconstrained. Moreover, their concluding argument that human concern for nonhuman nature should be understood in terms of aesthetic values rather than moral values does not provide reliable grounds for the systematic protection of nonhuman nature.
