The problem of finite-time stability of switched genetic regulatory networks with time-varying delays via Wirtinger’s integral inequality is addressed in this study. A novel Lyapunov–Krasovskii functional is proposed to capture the dynamical characteristic of GRNs. Using Wirtinger’s integral inequality, reciprocally convex combination technique and the average dwell time method conditions in the form of linear matrix inequalities are established for finite-time stability of switched GRNs. The applicability of the developed finite-time stability conditions is validated by numerical results.

This long-awaited book replaces Hughes and Cresswell's two classic studies of modal logic: _An Introduction to Modal Logic_ and _A Companion to Modal Logic_. _A New Introduction to Modal Logic_ is an entirely new work, completely re-written by the authors. They have incorporated all the new developments that have taken place since 1968 in both modal propositional logic and modal predicate logic, without sacrificing tha clarity of exposition and approachability that were essential features of their earlier works. The book takes (...) readers from the most basic systems of modal propositional logic right up to systems of modal predicate with identity. It covers both technical developments such as completeness and incompleteness, and finite and infinite models, and their philosophical applications, especially in the area of modal predicate logic.

Context: The majority of contemporary enactivist work is influenced by the philosophical biology of Hans Jonas. Jonas credits all living organisms with experience that involves particular “existential” structures: nascent forms of concern for self-preservation and desire for objects and outcomes that promote well-being. We argue that Jonas’s attitude towards living systems involves a problematic anthropomorphism that threatens to place enactivism at odds with cognitive science, and undermine its legitimate aims to become a new paradigm for scientific investigation and understanding of (...) the mind. Problem: Enactivism needs to address the tension between its Jonasian influences and its aspirations to become a new paradigm for cognitive science. By relying on Jonasian phenomenology, contemporary enactivism obscures alternative ways in which phenomenology can be more smoothly integrated with cognitive science. Method: We outline the historical relationship between enactivism and phenomenology, and explain why anthropomorphism is problematic for a research program that aspires to become a new paradigm for cognitive science. We examine the roots of Jonas’s existential interpretation of biological facts, and describe how and why Jonas himself understood his project as founded on an anthropomorphic assumption that is incompatible with a crucial methodological assumption of scientific enquiry: the prohibition of unexplained natural purposes. We describe the way in which phenomenology can be integrated into Maturana’s autopoietic theory, and use this as an example of how an alternative, non-anthropomorphic science of the biological roots of cognition might proceed. Results: Our analysis reveals a crucial tension between Jonas’s influence on enactivism and enactivism’s paradigmatic aspirations. This suggests the possibility of, and need to investigate, other ways of integrating phenomenology with cognitive science that do not succumb to this tension. Implications: In light of this, enactivists should either eliminate the Jonasian inference from properties of our human experience to properties of the experience of all living organisms, or articulate an alternative conception of scientific enquiry that can tolerate the anthropomorphism this inference entails. The Maturanian view we present in the article’s final section constitutes a possible framework within which enactivist tools and concepts can be used to understand cognition and phenomenology, and that does not involve a problematic anthropomorphism. Constructivist content: Any constructivist approach that aims for integration with current scientific practice must either avoid the type of anthropomorphic inference on which Jonas bases his work, or specify a new conception of scientific enquiry that renders anthropomorphism unproblematic.

Consider orthodox motivational judgment internalism: necessarily, A’s sincere moral judgment that he or she ought to φ motivates A to φ. Such principles fail because they cannot accommodate the amoralist, or one who renders moral judgments without any corresponding motivation. The orthodox alternative, externalism, posits only contingent relations between moral judgment and motivation. In response I first revive conceptual internalism by offering some modifications on the amoralist case to show that certain community-wide motivational failures are not conceptually possible. Second, I (...) introduce a theory of moral motivation that supplements the intuitive responses to different amoralist cases. According to moral judgment purposivism (MJP), in rough approximation, a purpose of moral judgments is to motivate corresponding behaviors such that a mental state without this purpose is not a moral judgment. MJP is consistent with conceptual desiderata, provides an illuminating analysis of amoralist cases, and offers a step forward in the internalist-externalist debates. (shrink)

We owe the problem of the speckled hen to Gilbert Ryle. It was suggested to A.J. Ayer by Ryle in connection with Ayer’s account of seeing. Suppose that you are standing before a speckled hen with your eyes trained on it. You are in good light and nothing is obstructing your view. You see the hen in a single glance. The hen has 47 speckles on its facing side, let us say, and the hen ap­ pears speckled to you. On (...) Ayer’s view, in seeing the hen, you directly see a speckled sense-datum or appearance. Ryle wondered how many speckles there are on the sense-datum. After all, intu­ itively, the hen does not appear to you to have 47 speckles. And if this is the case, then it does not present to you an appearance with 47 speckles. Equally, however, the hen does not appear to you not to have 47 speckles. So, it does not present an appearance that lacks 47 speckles either. (shrink)

The goal of this paper is to examine whether business performance is affected by the adoption of practices included under the term Corporate Social Responsibility (CSR). To achieve this goal, we analyse the relation between CSR and certain accounting indicators and examine whether there exist significant differences in performance indicators between European firms that have adopted CSR and others that have not. The effects of compliance with the requirements of CSR were determined on the basis of firms included in the (...) Dow Jones Sustainability Index (DJSI), and specific accounting indicators were applied to measure performance. For the purposes of this study, we selected one group of firms belonging to the DJSI and another comprised of firms quoted on the Dow Jones Global Index (DJGI) but not on the DJSI. The sample was made up of two groups of 55 firms, studied for the period 1998–2004. Empirical analysis supports the conclusion that differences in performance exist between firms that belong to the DJSI and to the DJGI and that these differences are related to CSR practices. We find that a short-term negative impact on performance is produced. (shrink)

Context: Direct realism is a non-reductive, anti-representationalist theory of perception lying at the heart of mainstream analytic philosophy, where it is currently generating a lot of interest. For all that, it is widely held to be both controversial and anti-scientific. On the other hand, the sensorimotor theory of perception initially generated a lot of interest within enactive philosophy of cognitive science, but has arguably not yet delivered on its initial promise. Problem: I aim to show that the sensorimotor theory and (...) direct realism complement each other, and that the result is a philosophically radical, but fully scientifically realised, theory of perception. Method: The article uses philosophical analysis and discussion. It also draws on empirical evidence from the relevant cognitive sciences. Results: Direct realism can be augmented by sensorimotor theory to become a scientifically tractable alternative to the mainstream, representationalist research programme within cognitive science. Implications: The article aims to further clarify the philosophical importance of the sensorimotor approach to perception. It also aims to show that the apparently radical claim that we perceive objects themselves is amenable to normal scientific study. Constructivist content: Objects are analysed as a kind of collaboration between the world and the perceiver. On this account, we can never perceive outside the categories of our own understanding, but we do perceive genuinely outside our own heads. Thus, the approach here is not exactly constructivism, though it shares many goals and results with constructivism. (shrink)

Cappelen and Hawthorne’s Relativism and Monadic Truth (2009) offers an extended defense of a thesis they call simplicity, which, in brief, holds that propositions are true or false simpliciter. Propositions are cast in their traditional roles as the contents of assertions, and as the semantic values of declarative sentences in contexts. Simplicity stands in sharp contrast to forms of relativism including, for instance, a form that hold that our claims are true or false only relative to a judge. This applies (...) especially to claims of taste, which come out true or false only relative to the judge who finds things tasty (e.g. Glanzberg 2007, Lasersohn 2005). But simplicity also rejects the more widespread temporalist view that propositions are true or false only relative to a time, and it rejects the even more widely held view that propositions are true or false only relative to a world. One reason that has been advanced for temporalism, e.g. by Kaplan (1989), is that our languages seem to contain non-trivial temporal operators. Hence, the argument goes, the semantic values of sentences need to be temporally neutral, i.e. vary for truth or falsehood with time. The same goes for possible worlds and modal operators. Hence, Kaplan and many others think of the semantic values of sentences as sets of world-time pairs. It has been tempting to apply this sort of argument much more widely, to see the semantic values of sentences as varying not just with world and time, but perhaps with location and other parameters as well.

Numerous studies indicate that racial minorities are both more likely to be executed for murder and that those who murder them are less likely to be executed than if they murder whites. Death penalty opponents have long attempted to use these studies to argue for a moratorium on capital punishment. Whatever the merits of such arguments, they overlook the fact that such discrimination alters the costs of murder; racial discrimination imposes higher costs on minorities for murdering through tougher sentences, and (...) it imposes lower costs on whites for murdering minorities by dispensing weaker sentences. These cost differentials constitute an injustice not simply to actual minority defendants in capital cases, nor simply to the actual minority victims of murder, but to all members of minority communities. I here offer two arguments for a moratorium on capital punishment: The first draws upon evidence of racial discrimination against minority defendants in capital cases, and claims that such discrimination modifies the costs of murder in such a way that minority individuals do not enjoy equal status under the law. The second draws upon the evidence regarding racial discrimination in relation to the race of victims, and claims that such discrimination modifies the costs of murder in such a way that minority individuals do not enjoy the equal protection of the law. Thus, by not assigning equal costs to murder, the American criminal justice system fails to provide racial minorities the equality under the law and discounts the value of their lives and liberties. A moratorium is the least unjust response to such a social injustice. I also reply to the criticism that a moratorium prevents us from executing deserving murderers. (shrink)

A chip looks true blue to John and greenish blue to Jane. On the face of it, at least one of the two perceivers has an inaccurate colour experience; for the chip cannot be both true blue and greenish blue. But John and Jane are “normal” perceivers, and there is no privileged class of normal perceivers (Block 1999). This is the puzzle of true blue (Tye.

Of the many problems of history and culture, the problem of correct understanding and interpretation of universal symbols, as well as their wise use, is very relevant. Since the subject of the study is not individual symbols, and not even symbolic systems, but the outlook component of the transformation of symbols, in the field of research is the interaction of culture and its creator - a person whose change of position leads to a change in the interpretation of symbols, and (...) therefore changes in the symbolism. The main task of the article is to understand the phenomenon of the symbol and its transformation in a single structure of history and culture. (shrink)

The usual definition of (non-contextual) hidden variables is found to be too restrictive, in the sense that, according to it, even some classical systems do not admit hidden variables. A more general concept is introduced and the term “approximate hidden variables” is used for it. This new concept avoids the aforementioned problems, since all classical systems admit approximate hidden variables. Standard quantum systems do not admit approximate hidden variables, unless the corresponding Hilbert space is 2-dimensional. However, an appropriate non-standard quantum (...) system, which arises by focussing on momentum and position and neglecting the remaining observables, admits approximate hidden variables. Systems associated with JBW-algebras (resp. von Neumann algebras) and satisfying some mild conditions admit approximate hidden variables iff they are classical, that is, iff the corresponding JBW-algebra (resp. von Neumann algebra) is associative (resp. commutative).

In this paper I argue that Martha Nussbaum's Aristotelian analysis of compassion and pity is faulty, largely because she fails to distinguish between an emotion's basic constitutive conditions and the associated constitutive or "intrinsic" norms, "extrinsic" normative conditions, for instance, instrumental and moral considerations, and the causal conditions under which emotion is most likely to be experienced. I also argue that her defense of compassion and pity as morally valuable emotions is inadequate because she treats a wide variety of objections (...) as all stemming from a common commitment to a Stoic conception of the good. I argue that these objections can be construed as neutral between conceptions of the good. I conclude by arguing that construed in this way there are nonetheless plausible replies to these objections. (shrink)

It is sometimes suggested that expressivism in meta-ethics is to be criticized on grounds which do not themselves concern meta-ethics in particular, but which rather concern philosophy of language more generally. Frank Jackson and Philip Pettit (1998; see also Jackson and Pettit 1999, and Jackson 2001) have recently advanced a novel version of such an argument. They begin by noting that expressivism in its central form makes two claims—that ethical sentences are not truth evaluable, and that to assert an ethical (...) sentence is to express one’s desires or feelings rather than to report a fact. They then argue that, given some plausible premises in the philosophy of language emanating mainly from Locke, the two central claims of expressivism are contradictory: when combined with the plausible premises, they say, the second claim refutes the first. The purpose of this paper is to formulate Jackson and Pettit’s Lockean argument, and to suggest that it fails. (shrink)

We motivate and introduce a new method of abduction, Matrix Abduction, and apply it to modelling the use of non-deductive inferences in the Talmud such as Analogy and the rule of Argumentum A Fortiori. Given a matrix $${\mathbb {A}}$$ with entries in {0, 1}, we allow for one or more blank squares in the matrix, say a i,j =?. The method allows us to decide whether to declare a i,j = 0 or a i,j = 1 or a i,j =? (...) undecided. This algorithmic method is then applied to modelling several legal and practical reasoning situations including the Talmudic rule of Kal-Vachomer. We add an Appendix showing that this new rule of Matrix Abduction, arising from the Talmud, can also be applied to the analysis of paradoxes in voting and judgement aggregation. In fact we have here a general method for executing non-deductive inferences. (shrink)

Vagueness, as discussed in the philosophical literature, is the phenomenon that paradigmatically rears its head in the sorites paradox, one prominent version of which is: One grain of sand does not make a heap. For any n, if n grains of sand do not make a heap, then n + 1 grains of sand do not make a heap. So, ten billion grains of sand do not make a heap. It is common ground that the different versions of the sorites (...) paradox arise because of vagueness in a key expression, in this case ‘heap’. One central concern in the literature on vagueness is to find a solution to the sorites paradox. Vagueness also gives rise to borderline cases. Since ‘heap’ is a vague expression, ‘heap’ also gives rise to borderline cases: there are some possible entities such that they are neither clearly heaps nor clearly non-heaps, but instead are borderline heaps. Borderline cases can seem intuitively to present counter-examples to bivalence and the law of excluded middle . If Harry is a borderline case of baldness, ‘Harry is bald’ can seem neither true nor false, whence it presents doubts concerning bivalence. Similarly, one can find the corresponding instance of LEM, ‘Either Harry is bald or Harry is not bald’, suspect. There are three main theories that involve departures from bivalence, and two of them involve rejection of LEM as well. Standard three-valued logic invokes the idea of a third truth-value or truth-value gaps; fuzzy logic invokes the idea of continuum-many truth-values intermediate between truth and falsity. Both these views preserve truth-functionality. Traditional supervaluationism involves rejection of bivalence, but adherence to LEM. The idea is that if an expression is vague there is a range of precisifications associated with it, where, roughly, precisifications are ways the expression could be …. (shrink)

In “Imposing Risks,” Judith Thomson gives a case in which, by turning on her stove, she accidentally causes her neighbor’s death. She claims that both the following are true: (1) she ought not to have caused her neighbor’s death; (2) it was permissible for her to turn her stove on. In this paper it is argued that it cannot be that both (1) and (2) are true, that (2) is true, and that therefore (1) is false. How this is so (...) is explained, and the implications of this position regarding the relation between rights and duties is explored. (shrink)

This volume provides a comprehensive presentation of the philosophical work of the fifteenth-century Renaissance thinker Giovanni Pico della Mirandola. In essays specially commissioned for this book, a distinguished group of scholars presents the central topics and texts of Pico's literary output. Best known as the author of the celebrated 'Oration on the Dignity of Man', Pico also wrote several other prominent works. They include an influential diatribe against astrology, an ambitious metaphysical treatise attempting to reconcile Platonic and Aristotelian metaphysical views, (...) and writings on a range of subjects such as magic, Kabbalah, the Church, philosophy of religion, and philosophy of knowledge. The first volume of its kind in English, this collection of essays will be of value not only to advanced students and specialists of late medieval and Renaissance thought, but also to those interested in Italian humanism and Renaissance Aristotelianism and Neoplatonism.

A few results generalizing well-known classical model theory ones have been obtained in institution theory these last two decades (e.g. Craig interpolation, ultraproduct, elementary diagrams). In this paper, we propose a generalized institution-independent version of the Beth definability theorem.

This essay begins with a Native American women's perspective on Early Feminism which came about as a result of Euroamerican patriarchy in U. S. society. It is followed by the myth of "tribalism," regarding the language and laws of U. S. colonialism imposed upon Native American peoples and their respective cultures. This colonialism is well documented in Federal Indian law and public policy by the U. S. government, which includes the state as well as federal level. The paper proceeds to (...) compare and contrast these Native American women's experiences with pre-patriarchal and pre-colonialist times, in what can be conceptualized as "indigenous kinship" in traditional communalism; today, these Native American societies are called "tribal nations" in contrast to the Supreme Court Marshall Decision which labeled them "domestic dependent nations." This history up to the present state of affairs as it affects Native American women is contextualized as "patriarchal colonialism" and biocolonialism in genome research of indigenous peoples, since these marginalized women have had to contend with both hegemonies resulting in a sexualized and racialized mindset. The conclusion makes a statement on Native American women and Indigensim, both in theory and practice, which includes a native Feminist Spirituality in a transnational movement in these globalizing times. The term Indigensim is conceptualized in a postcolonialist context, as well as a perspective on Ecofeminism to challenge what can be called a "trickle down patriarchy" that marks male dominance in tribal politics. A final statement calls for "Native Womanism" in the context of sacred kinship traditions that gave women respect and authority in matrilineal descendency and matrifocal decision making for traditional gender egalitarianism.

Upshot: We respond to three main challenges that the commentaries have raised. First, we argue that to deal successfully with the hard problem of consciousness, it is not enough to posit a remedy by which to move beyond the hard problem. Second, we argue that it makes no sense to explain identity. Yet this does not commit us to definitions by fiat. The strategy we pursue here, and in the target article, is not to explain identity but to explain away (...) the appearance of non-identity. Finally, while we are sympathetic to Varela’s call for a paradigm shift in consciousness studies, we argue here, and in the target article, that this call can only be properly successful if the hard problem is dismantled.

Open peer commentary on the article “Exploring the Depth of Dream Experience: The Enactive Framework and Methods for Neurophenomenological Research” by Elizaveta Solomonova & Xin Wei Sha. Upshot: This commentary focuses on an ontological claim made by the authors of this target article: that perceiving, imagining and dreaming are inseparable. It explores how best to understand this “inseparability condition.” It is shown that the evidence needed to justify a strict reading of the inseparability condition is lacking, while there is room (...) for a more relaxed rendition of the inseparability condition. The inferred lesson is that in developing an enactive neurophenomenology of dreaming, it is a non-trivial task to achieve clarity about the ontology of dreaming, and its relationship to imagining as well as perceiving.

As a first comment it should not be taken that we have any argument against the consistency of Mellor’s actualist version of the B-theory. Not only have we no argument; we hold that Mellor’s position is consistent. As far as logic goes we believe that you can translate A into B, and B into A. Mellor takes a quotation from our article as endorsing the policy of doing for time just what you do for modality, and vice versa, and it (...) is true that you can take our sentence that way. It is also true that we are sympathetic to an equal treatment of these two, but it is important to acknowledge that nothing in the logic forces you to do this. In particular, we agree with Mellor that practically no one treats space in an A-theory manner – even though it is logically consistent to do so. Our concern is solely with Mellor’s argument that a certain position in the temporal case is inconsistent where the analogous modal position is not. And our paper is addressed not so much to Mellor’s own position as to an A-theorist who wants to escape the consequences of Mellor’s argument by doing for time what Mellor does for modality. In fact, there is a position against which Mellor’s argument is successful. As far as we can tell the version we shall present is, if not precisely what Mellor has in mind, close to it, or at least sufficiently like it to illustrate his reply in a form in which we are able to comment on it. Mellor’s example is of Jim who …. (shrink)

A review of economic thought since the sixteenth century reveals two streams of economic discourse, dirigisme and laissez-faire. Starting with the mercantilists, dirigiste approaches to economics embrace the real-world complexity of commodities that often differ greatly in attributes that are growth- and rent- augmenting. Most importantly, this means that free trade is likely to be polarising: it concentrates growth- and rent-augmenting commodities in countries that already enjoy a head start in these commodities. Advanced countries, therefore, support laissez-faire, while lagging countries (...) tend to support dirigisme. In order to rationalise their laissez-faire stance, advanced countries began developing a new economic discourse that strips commodities of their complexity. The foundations for this ideological reconstruction of economics were first laid by Adam Smith; this process eventually reached its climax with the neoclassical economists who stripped commodities down to one attribute: their capital intensity. In opposition to this laissez-faire economics, other writers, supportive of the interests of lagging countries, brought complexity back into their economic discourse; they argued that lagging countries had a fighting chance of catching up to advanced economies only by indigenising a growing array of growth- and rent-augmenting commodities.
