Advocates have sought to prove that underdetermination obtains because all theories have empirical equivalents. But algorithms for generating empirical equivalents simply exchange underdetermination for familiar philosophical chestnuts, while the few convincing examples of empirical equivalents will not support the desired sweeping conclusions. Nonetheless, underdetermination does not depend on empirical equivalents: our warrant for current theories is equally undermined by presently unconceived alternatives as well-confirmed merely by the existing evidence, so long as this transient predicament recurs for each theory and body (...) of evidence we consider. The historical record supports the claim that this recurrent, transient underdetermination predicament is our own. (shrink)

In recent years, many philosophers of modern physics came to the conclusion that the problem of how objectivity is constituted (rather than merely given) can no longer be avoided, and therefore that a transcendental approach in the spirit of Kant is now philosophically relevant. The usual excuse for skipping this task is that the historical form given by Kant to transcendental epistemology has been challenged by Relativity and Quantum Physics. However, the true challenge is not to force modern physics into (...) a rigidly construed static version of Kant's philosophy, but to provide Kant's method with flexibility and generality. In this book, the top specialists of the field pin down the methodological core of transcendental epistemology that must be used in order to throw light on the foundations of modern physics. First, the basic tools Kant used for his transcendental reading of Newtonian Mechanics are examined, and then early transcendental approaches of Relativistic and Quantum Physics are revisited. Transcendental procedures are also applied to contemporary physics, and this renewed transcendental interpretation is finally compared with structural realism and constructive empiricism. The book will be of interest to scientists, historians and philosophers who are involved in the foundational problems of modern physics. (shrink)

There are two general classes of social conventions: conventions of coordination, and conventions of partial conflict. In coordination problems, the interests of the agents coincide, while in partial conflict problems, some agents stand to gain only if other agents unilaterally make certain sacrifices. Lewis' (1969) pathbreaking analysis of convention in terms of game theory focuses on coordination problems, and cannot accommodate partial conflict problems. In this paper, I propose a new game-theoretic definition of convention which generalizes previous game-theoretic definitions (Lewis (...) 1969, Vanderschraaf 1995), and which can be used to characterize norms of justice in partial conflict situations. I argue that the key structural property necessary for a social arrangement to be a convention is that it be conditionally self-enforcing, in the sense that: (i) each agent has a decisive reason to follow her end of the arrangement given that she expects all to do likewise, (ii) given a different set of expectations, some agents would have had a decisive reason to deviate, and (iii) these facts are common knowledge. This leads to a definition of convention as a strict correlated equilibrium (Aumann 1974) together with appropriate common knowledge conditions. Examples are given in which it is shown how this more general account of convention can be used to analyze norms of justice as well as coordination problems. It is only a general sense of common interest; which sense all the members of the society express to one another, and which induces them to regulate their conduct by certain rules. I observe, that it will be for my interest to leave another in the possession of his goods, provided he will act in the same manner with regard to me. He is sensible of a like interest in the regulation of his conduct. When this common sense of interest is mutually express'd, and is known to both, it produces a suitable resolution and behavior. And this may properly be call'd a convention or agreement betwixt us,.. (shrink)

Jewish law takes an approach to self-defense that differs dramatically from the conventional assumptions of Western secular legal systems. The central theme of Talmudic jurisprudence is that self-defense rests on a duty not to stand idly by while one's neighbor suffers. “Do not stand on the blood of one's neighbor,” as the point is cryptically put in Leviticus 19:16. This way of thinking about self-defense departs in two significant ways from common Western assumptions. First, it stresses that the roots of (...) self-defense are a duty rather than a right to act; second, it treats the case of third-party defense as logically prior to the first-party case of self -defense.

Hume's 'Natural History of Religion' offers a naturalized account of the causes of religious thought, an investigation into its 'origins' rather than its 'foundation in reason'. Hume thinks that if we consider only the causes of religious belief, we are provided with a reason to suspend the belief. I seek to explain why this is so, and what role the argument plays in Hume's wider campaign against the rational acceptability of religious belief. In particular, I argue that the work threatens (...) a form of fideism which maintains that it is rationally permissible to maintain religious belief in the absence of evidence or of arguments in its favour. I also discuss the 'argument from common consent', and the relative superiority of Hume's account of the origins of religious belief. (shrink)

Integrated information theory (IIT) is a candidate theory of consciousness that highlights the role of complex interactions between parts of a system as the basis of consciousness – and, due to its general information-theoretic formulation, is capable of making statements about consciousness in neural and non-neural systems alike. Here, we argue that a system radically different to a human brain, host to complex physiological and functional structures capable of integrating information, can be found in the meristems and vascular system of (...) higher plants. Following a pragmatic and ontologically innocent approach, neither taking for granted that plants are conscious nor dismissing the possibility that they are, we argue that the time is ripe to apply analysis tools inspired by IIT to plants, taking advantage of recent developments in both plant imaging and information theory. We introduce and discuss the relevant literature, and pro information and integration in plant behaviour, assessing the plausibility of plant sentience. If successful, these experiments could position plants as the next frontier in consciousness science, and urge us to rethink our perspectives on consciousness, how to measure it, and its prevalence amongst living beings.

Optimization by definition is the action of making most effective or the best use of a resource or situation and that is required almost in every field of engineering. In this work, the optimization of Least Mean square (LMS) algorithm is carried out with the help of Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO). Efforts have been made to find out the advantages and disadvantages of combining gradient based (LMS) algorithm with Swarm Intelligence SI (ACO, PSO). This optimization (...) of LMS algorithm will help us in further extending the uses of adaptive filtering to the system having multi-model error surface that is still a gray area of adaptive filtering. Because the available version of LMS algorithm that plays an important role in adaptive filtering is a gradient based algorithm, that get stuck at the local minima of system with multi-model error surface considering it global minima, resulting in an non-optimized convergence. By virtue of the proposed method we have got a profound solution for the problem associated with system with multimodal error surface. The results depict significant improvements in the performance and displayed fast convergence rate, rather stucking at local minima. Both the SI techniques displayed their own advantage and can be separately combined with LMS algorithm for adaptive filtering. This optimization of LMS algorithm will further help to resolve serious interference and noise issues and holds a very important application in the field of biomedical science. (shrink)

Central to Thomas Sprat's History of the Royal Society was the description and justification of the method adopted and advocated by the Fellows of the Society, for it was thought that it was their method which distinguished them from ancients, dogmatists, sceptics, and contemporary natural philosophers such as Descartes. The Fellows saw themselves as furthering primarily a novel method, rather than a system, of philosophy, and the History gave expression to this corporate self-perception. However, the History's description of their method (...) was not necessarily accurate. Rather, as will be argued below, by a combination of subtle misrepresentation and selective exposition, Sprat portrayed a method which would further the aims of social and ecclesiastical stability and material prosperity, essential for the Royal Society since its continued existence depended upon the creation of a social basis for the institutionalized pursuit of natural philosophy. Some link had to be forged between the activities of the Society and the intellectual and social aspirations of the Restoration. To understand the intent and meaning of Sprat's History and the method there portrayed, we must therefore look to the institutional needs which it fulfilled. (shrink)

The prospect of using cell-based interventions to treat neurological conditions raises several important ethical and policy questions. In this target article, we focus on issues related to the unique constellation of traits that characterize CBIs targeted at the central nervous system. In particular, there is at least a theoretical prospect that these cells will alter the recipients' cognition, mood, and behavior—brain functions that are central to our concept of the self. The potential for such changes, although perhaps remote, is cause (...) for concern and careful ethical analysis. Both to enable better informed consent in the future and as an end in itself, we argue that early human trials of CBIs for neurological conditions must monitor subjects for changes in cognition, mood, and behavior; further, we recommend concrete steps for that monitoring. Such steps will help better characterize the potential risks and benefits of CBIs as they are tested and potentially used for treatment. (shrink)

The Secret Doctrine comprises a virtual encyclopaedia of the "anciently universal wisdom-tradition" -- scarcely an issue of consequence in the broad range of human experience is left untouched. As part of the Secret Doctrine Centenary project, this 441-page Index provides ready access to the vast quantity of material from many cultures set forth in the SD's original two volumes published in 1888. Due to the topics covered, it is as much an index of ideas as it is of subjects, works, (...) persons, and proper names. To aid the reader, major subject entries are cross-referenced; foreign terms are identified by language and, where possible, given in both their 1888 spelling(s) and as modernly transliterated, often with one or two word definitions. Subentries are arranged alphabetically. Cited works and authors, whose titles or names are not given in the SD are placed in brackets for convenient identification. Also included is an Appendix of foreign phrases with translation and source reference -- all helping to make this Index an invaluable reference tool for students of The Secret Doctrine. (shrink)

We show that Leitgeb’s dependence operator of Leitgeb is a \-operator and that this is best possible.

It is shown, assuming the linear case of Schinzel's Hypothesis, that the first-order theory of the structure $\langle \omega; +, P\rangle$ , where P is the set of primes, is undecidable and, in fact, that multiplication of natural numbers is first-order definable in this structure. In the other direction, it is shown, from the same hypothesis, that the monadic second-order theory of $\langle\omega; S, P\rangle$ is decidable, where S is the successor function. The latter result is proved using a general (...) result of A. L. Semenov on decidability of monadic theories, and a proof of Semenov's result is presented. (shrink)

The quest for molecular mechanisms that guide axons or specify synaptic contacts has largely focused on molecules that intuitively relate to the idea of an “instruction.” By contrast, “permissive” factors are traditionally considered background machinery without contribution to the information content of a molecularly executed instruction. In this essay, I recast this dichotomy as a continuum from permissive to instructive actions of single factors that provide relative contributions to a necessarily collaborative effort. Individual molecules or other factors do not constitute (...) absolute instructions by themselves; they provide necessary context for each other, thereby creating a composite that defines the overall instruction. The idea of composite instructions leads to two main conclusions: first, a composite of many seemingly permissive factors can define a specific instruction even in the absence of a single dominant contributor; second, individual factors are not necessarily related intuitively to the overall instruction or phenotypic outcome.

The paper explores the status of the proposition "God exists" in late scholastic debates of the sixteenth and seventeenth centuries in some key authors of the era. A proposition is said to be self-evident if its truth is known solely from the meaning of the terms and is not inferred from other propositions. It does not appear to be immediately evident from the terms that God exists, for the concept expressed by "God" is based on the relation to creatures and (...) negation of imperfection and does not reach to the divine essence. Thomas Aquinas maintains that there are two types of self-evident propositions: those self-evident in themselves but not to us and those self-evident in themselves as well as to us. "God exists" is of the fi rst type. For Scotus a self-evident proposition is such that if its terms are conceived by any intellect, the truth of the proposition becomes known from the terms, non-inferentially. In his view there is no distinction between a self-evident proposition in itself and that in relation to us, because any proposition self-evident in itself is known to be such to any intellect, even though it might not be actually known; it would be known, provided that the terms are conceived. So for Scotus the sentence "God exists" expresses diff erent propositions for the blessed in heaven, the angels and God on the one hand and humans on the other. The former is self-evident, the latter is not. While later scholastics accept either the solution of Thomas or that of Scotus, according to which "God exists" is not self-evident for humans, Thomas de Argentina diff ers in that for him "God exists" is self-evident for humans too. The position of Thomas Aquinas was defended by Domingo Ban¯ez, Francisco Zumel and Gregorio de Valentia. In contrast, Johannes Poncius was a famous adherent of Scotus. There is a fair number of scholastics harmonizing the doctrine of Thomas and Scotus: Bernard Sannig, Luis de Molina, Gabriel Vázquez, Rodrigo de Arriaga and Jean Lalemandet. According to these authors, when Thomas says that "God exists" is self-evident in itself, he speaks about the extensional proposition, i.e. the state of affairs being conceptualized, which does not contradict Scotus’s teaching. © FILOSOFIA, 2013.
