    Possible Worlds Semantics for Partial Meet Multiple Contraction.Maurício D. L. Reis & Eduardo Fermé - 2012 - Journal of Philosophical Logic 41 (1):7-28.
    In the logic of theory change, the standard model is AGM, proposed by Alchourrón et al. (J Symb Log 50:510–530, 1985 ). This paper focuses on the extension of AGM that accounts for contractions of a theory by a set of sentences instead of only by a single sentence. Hansson (Theoria 55:114–132, 1989 ), Fuhrmann and Hansson (J Logic Lang Inf 3:39–74, 1994 ) generalized Partial Meet Contraction to the case of contractions by (possibly non-singleton) sets of sentences. In (...)

    Multiple Kernel Contraction.Eduardo Fermé, Karina Saez & Pablo Sanz - 2003 - Studia Logica 73 (2):183 - 195.
    This paper focuses on the extension of AGM that allows change for a belief base by a set of sentences instead of a single sentence. In [FH94], Fuhrmann and Hansson presented an axiomatic for Multiple Contraction and a construction based on the AGM Partial Meet Contraction. We propose for their model another way to construct functions: Multiple Kernel Contraction, that is a modification of Kernel Contraction, proposed by Hansson [Han94] to construct classical AGM contractions (...)

    Multiple and Iterated Contraction Reduced to Single-Step Single-Sentence Contraction.Sven Ove Hansson - 2010 - Synthese 173 (2):153-177.
    Multiple contraction (simultaneous contraction by several sentences) and iterated contraction are investigated in the framework of specified meet contraction (s.m.c.) that is extended for this purpose. Multiple contraction is axiomatized, and so is finitely multiple contraction (contraction by a finite set of sentences). Two ways to reduce finitely multiple contraction to contraction by single sentences are introduced. The reduced operations are axiomatically characterized and their properties are investigated. (...)

    System of Spheres-Based Multiple Contractions.Eduardo Fermé & Maurício D. L. Reis - 2012 - Journal of Philosophical Logic 41 (1):29-52.
    We propose a new class of multiple contraction operations — the system of spheres-based multiple contractions — which are a generalization of Grove’s system of spheres-based (singleton) contractions to the case of contractions by (possibly non-singleton) sets of sentences. Furthermore, we show that this new class of functions is a subclass of the class of the partial meet multiple contractions.

    Maximal and Perimaximal Contraction.Sven Ove Hansson - 2013 - Synthese 190 (16):3325-3348.
    Generalizations of partial meet contraction are introduced that start out from the observation that only some of the logically closed subsets of the original belief set are at all viable as contraction outcomes. Belief contraction should proceed by selection among these viable options. Several contraction operators that are based on such selection mechanisms are introduced and then axiomatically characterized. These constructions are more general than the belief base approach. It is shown that partial meet contraction (...)

    Bootstrap Contraction.Sven Ove Hansson - 2013 - Studia Logica 101 (5):1013-1029.
    We can often specify how we would contract by a certain sentence by saying that this contraction would coincide with some other contraction that we know how to perform. We can for instance clarify that our contraction by p&q would coincide with our contraction by p, or by q, or by {p, q}. In a framework where the set of potential outcomes is known, some contractions are “self-evident” in the sense that there is only one serious (...)

    A Survey of Multiple Contractions.André Fuhrmann & Sven Ove Hansson - 1994 - Journal of Logic, Language and Information 3 (1):39-75.
    The AGM theory of belief contraction is extended tomultiple contraction, i.e. to contraction by a set of sentences rather than by a single sentence. There are two major variants: Inpackage contraction all the sentences must be removed from the belief set, whereas inchoice contraction it is sufficient that at least one of them is removed. Constructions of both types of multiple contraction are offered and axiomatically characterized. Neither package nor choice contraction can (...)

    Epistemic Entrenchment-Based Multiple Contractions.Eduardo Fermé & Maurício D. L. Reis - 2013 - Review of Symbolic Logic 6 (3):460-487.
    In this article we present a new class of multiple contraction functionswhich are a generalization of the epistemic entrenchment-based contractions (Grdenfors & Makinson, 1988) to the case of contractions by (possibly nonsingleton) sets of sentences and provide an axiomatic characterization for that class of functions. Moreover, we show that the class of epistemic entrenchment-based multiple contractions coincides with the class of system of spheres-based multiple contractions introduced in Fermé & Reis (2012).

    In Praise of Full Meet Contraction.Sven Ove Hansson - 2006 - Análisis Filosófico 26 (1):134-146.
    Full meet contraction, that was devised by Carlos Alchourrón and David Makinson in the early 1980' s, has often been overlooked since it is not in itself a plausible contraction operator. However, it is a highly useful building-block in the construction of composite contraction operators. In particular, all plausible contraction operators can be reconstructed so that the outcome of contracting a belief set K by a sentence p is defined as K ∼ f, where ∼ is (...)

    Constructive Order Theory.Marcel Erné - 2001 - Mathematical Logic Quarterly 47 (2):211-222.
    We introduce the notion of constructive suprema and of constructively directed sets. The Axiom of Choice turns out to be equivalent to the postulate that every supremum is constructive, but also to the hypothesis that every directed set admits a function assigning to each finite subset an upper bound. The Axiom of Multiple Choice implies a simple set-theoretical induction principle , stating that any system of sets that is closed under unions of well-ordered subsystems and contains all finite subsets (...)

    Infinitary Belief Revision.Dongmo Zhang & Norman Foo - 2001 - Journal of Philosophical Logic 30 (6):525-570.
    This paper extends the AGM theory of belief revision to accommodate infinitary belief change. We generalize both axiomatization and modeling of the AGM theory. We show that most properties of the AGM belief change operations are preserved by the generalized operations whereas the infinitary belief change operations have their special properties. We prove that the extended axiomatic system for the generalized belief change operators with a Limit Postulate properly specifies infinite belief change. This framework provides a basis for first-order belief (...)

    Rational Evaluation in Belief Revision.Yongfeng Yuan & Shier Ju - 2015 - Synthese 192 (7):2311-2336.
    We introduce a new operator, called rational evaluation, in belief change. The operator evaluates new information according to the agent’s core beliefs, and then exports the plausible part of the new information. It belongs to the decision module in belief change. We characterize rational evaluation by axiomatic postulates and propose two functional constructions for it, based on the well-known constructions of kernel sets and remainder sets, respectively. The main results of the paper are two representation theorems with respect to the (...)

    Financial Crisis Fatigue? Politics Behind Japan's Post-Global Financial Crisis Economic Contraction.Saori N. Katada - 2013 - Japanese Journal of Political Science 14 (2):223-242.
    Despite a relatively healthy financial sector, the Japanese economy contracted 6.3% in 2009 during the global financial crisis (GFC) after the Lehman shock, the starkest drop among the OECD countries. Since then, the Japanese economy has been slow to recover, although the Japanese government has implemented multiple economic stimulus packages with a high aggregate value.

    This paper extends earlier work by its authors on formal aspects of the processes of contracting a theory to eliminate a proposition and revising a theory to introduce a proposition. In the course of the earlier work, Gardenfors developed general postulates of a more or less equational nature for such processes, whilst Alchourron and Makinson studied the particular case of contraction functions that are maximal, in the sense of yielding a maximal subset of the theory (or alternatively, of one (...)

  20. Fish and Microchips: On Fish Pain and Multiple Realization.Matthias Michel - 2018 - Philosophical Studies 176 (9):2411-2428.
    Opponents to consciousness in fish argue that fish do not feel pain because they do not have a neocortex, which is a necessary condition for feeling pain. A common counter-argument appeals to the multiple realizability of pain: while a neocortex might be necessary for feeling pain in humans, pain might be realized differently in fish. This paper argues, first, that it is impossible to find a criterion allowing us to demarcate between plausible and implausible cases of multiple realization (...)

    Beyond Information Recall: Sophisticated Multiple-Choice Questions in Philosophy.J. Robert Loftis - 2019 - American Association of Philosophy Teachers Studies in Pedagogy 5:89-122.
    Multiple-choice questions have an undeserved reputation for only being able to test student recall of basic facts. In fact, well-crafted mechanically gradable questions can measure very sophisticated cognitive skills, including those engaged at the highest level of Benjamin Bloom’s taxonomy of outcomes. In this article, I argue that multiple-choice questions should be a part of the diversified assessment portfolio for most philosophy courses. I present three arguments broadly related to fairness. First, multiple-choice questions allow one to consolidate (...)

    Consider what the brain-state theorist has to do to make good his claims. He has to specify a physical–chemical state such that any organism (not just a mammal) is in pain if and only if (a) it possesses a brain of suitable physical–chemical structure; and (b) its brain is in that physical–chemical state. This means that the physical–chemical state in question must be a possible state of a mammalian brain, a reptilian brain, a mollusc’s brain (octopuses are mollusca, and certainly (...)

    Intersubjectivity and Multiple Realities in Zarathushtra's Gathas.Olga Louchakova-Schwartz - 2018 - Open Theology 4 (1):471-488.
    The Gathas, a corpus of seventeen poems in Old Avestan composed by the ancient Iranian poet-priest Zarathushtra (Zoroaster) ca. 1200 B.C.E., is the foundation document of Zoroastrian religion. Even though the dualistic axiology of the Gathas has been widely noted, it has proved very difficult to understand the meaning and genre of the corpus or the position of Zarathushtra’s ideas with regard to other religious philosophies. Relying on recent advances in translation and decryptions of Gathic poetry, I shall here develop (...)

    Natural Deduction with General Elimination Rules.Jan von Plato - 2001 - Archive for Mathematical Logic 40 (7):541-567.
    The structure of derivations in natural deduction is analyzed through isomorphism with a suitable sequent calculus, with twelve hidden convertibilities revealed in usual natural deduction. A general formulation of conjunction and implication elimination rules is given, analogous to disjunction elimination. Normalization through permutative conversions now applies in all cases. Derivations in normal form have all major premisses of elimination rules as assumptions. Conversion in any order terminates.Through the condition that in a cut-free derivation of the sequent Γ⇒C, no inactive weakening (...)

    Mario Villalobos and Pablo Razeto-Barry argue that enactivists should understand living beings not as autopoietic systems, but as autopoietic bodies. In doing so, they surrender the principle of multiple realizability of the spatial location of living beings. By way of counterexample, I argue that more motivation is required before this principle is surrendered.

    In the literature on multiple realizability and the identity theory, cases of neural plasticity have enjoyed a very limited role. The present article attempts to remedy this small influence by arguing that clinical and experimental evidence of quite extensive neural reorganization offers compelling support for the claim that psychological kinds are multiply realized in neurological kinds, thus undermining the identity theory. In particular, cases are presented where subjects with no measurable psychological deficits also have vast, though gradually received, neurological (...)

    In this paper I focus on a recently discussed phenomenon illustrated by sentences containing predicates of taste: the phenomenon of " perspectival plurality " , whereby sentences containing two or more predicates of taste have readings according to which each predicate pertains to a different perspective. This phenomenon has been shown to be problematic for (at least certain versions of) relativism. My main aim is to further the discussion by showing that the phenomenon extends to other perspectival expressions than predicates (...)

  29. Multiple Realizability and the Semantic View of Theories.Colin Klein - 2013 - Philosophical Studies 163 (3):683-695.
    Multiply realizable properties are those whose realizers are physically diverse. It is often argued that theories which contain them are ipso facto irreducible. These arguments assume that physical explanations are restricted to the most specific descriptions possible of physical entities. This assumption is descriptively false, and philosophically unmotivated. I argue that it is a holdover from the late positivist axiomatic view of theories. A semantic view of theories, by contrast, correctly allows scientific explanations to be couched in the most perspicuous, (...)

    Is Multiset Consequence Trivial?Petr Cintula & Francesco Paoli - forthcoming - Synthese:1-25.
    Dave Ripley has recently argued against the plausibility of multiset consequence relations and of contraction-free approaches to paradox. For Ripley, who endorses a nontransitive theory, the best arguments that buttress transitivity also push for contraction—whence it is wiser for the substructural logician to go nontransitive from the start. One of Ripley’s allegations is especially insidious, since it assumes the form of a trivialisation result: it is shown that if a multiset consequence relation can be associated to a closure (...)

    Has the Last Decade of Challenges to the Multiple Realization Argument Provided Aid and Comfort to Psychoneural Reductionists?John Bickle - 2010 - Synthese 177 (2):247 - 260.
    The previous decade has seen renewed critical interest in the multiple realization argument. These criticisms constitute a "second wave" of challenges to this central argument in late-20th century philosophy of mind. Unlike the first wave, which challenged the premise that multiple realization is inconsistent with reduction or type identity, this second wave challenges the truth of the multiple realization premise itself. Since psychoneural reductionism was prominent among the explicit targets of the multiple realization argument, one might (...)

    Jean Perrin and the Philosophers' Stories: The Role of Multiple Determination in Determining Avogadro's Number.Klodian Coko - forthcoming - Hopos: The Journal of the International Society for the History of Philosophy of Science.
    The French physicist Jean Baptiste Perrin is widely credited with providing the conclusive argument for atomism. The most well-known part of Perrin’s argument is his description of thirteen different procedures for determining Avogadro’s number (N)–the number of atoms, ions, and molecules contained in a gram-atom, gram-ion, and gram-mole of a substance, respectively. Because of its success in ending the atomism debates Perrin’s argument has been the focus of much philosophical interest. The various philosophers, however, have reached different conclusions, not only (...)

    This paper reorganizes and further develops the theory of partial meet contraction which was introduced in a classic paper by Alchourron, Gardenfors, and Makinson. Our purpose is threefold.

    Multiple Realization by Compensatory Differences.Kenneth Aizawa - 2013 - European Journal for Philosophy of Science 3 (1):69-86.
    One way that scientifically recognized properties are multiply realized is by “compensatory differences” among realizing properties. If a property G is jointly realized by two properties F1 and F2, then G can be multiply realized by having changes in the property F1 offset changes in the property F2. In some cases, there are scientific laws that articulate how distinct combinations of physical quantities can determine one and the same value of some other physical quantity. One moral to draw is that (...)

    In fMRI research, the goal of correcting for multiple comparisons is to identify areas of activity that reflect true effects, and thus would be expected to replicate in future studies. Finding an appropriate balance between trying to minimize false positives (Type I error) while not being too stringent and omitting true effects (Type II error) can be challenging. Furthermore, the advantages and disadvantages of these types of errors may differ for different areas of study. In many areas of social (...)

    In this article we explore multiple change operators, i.e., operators in which the epistemic input is a set of sentences instead of a single sentence. We propose two types of change: prioritized change, in which the input set is fully accepted, and symmetric change, where both the epistemic state and the epistemic input are equally treated. In both kinds of operators we propose a set of postulates and we present different constructions: kernel changes and partial meet changes.

  40. Propositions and Multiple Indexing.Brian Rabern - 2012 - Thought: A Journal of Philosophy 1 (2):116-124.
    It is argued that propositions cannot be the compositional semantic values of sentences (in context) simply due to issues stemming from the compositional semantics of modal operators (or modal quantifiers). In particular, the fact that the arguments for double indexing generalize to multiple indexing exposes a fundamental tension in the default philosophical conception of semantic theory. This provides further motivation for making a distinction between two sentential semantic contents—what (Dummett 1973) called “ingredient sense” and “assertoric content”.

    Collective action processes in complex, multiple-use common-pool resources (CPRs) have only recently become a focus of study. When CPRs evolve into more complex systems, resource use by separate user groups becomes increasingly interdependent. This implies, amongst others, that the institutional framework governing resource use has to be re-negotiated to avoid adverse impacts associated with the increased access of any new stakeholders, such as overexploitation, alienation of traditional users, and inter-user conflicts. The establishment of “platforms for resource use negotiation” is (...)

    Eden Inverted: On the Wild Self and the Contraction of Consciousness.Eugene Halton - 2007 - The Trumpeter 3 (23):45-77.
    The conditions of hunting and gathering through which one line of primates evolved into humans form the basis of what I term the wild self, a self marked by developmental needs of prolonged human neoteny and by deep attunement to the profusion of communicative signs of instinctive intelligence in which relatively “unmatured” hominids found themselves immersed. The passionate attunement to, and inquiry into, earth-drama, in tracking, hunting, foraging, rhythming, singing, and other arts/sciences, provided the trail to becoming human, and provide (...)

  44. Realization and Multiple Realization, Chicken and Egg.Thomas W. Polger - 2015 - European Journal of Philosophy 23 (4):862-877.
    A common view is that the truth of multiple realization—e.g., about psychological states—entails the truth of functionalism. This is supposed to follow because what is multiply realized is eo ipso realized. I argue that view is mistaken by demonstrating how it misrepresents arguments from multiple realization. In particular, it undermines the empirical component of the arguments, and renders the multiplicity of the realization irrelevant. I suggest an alternative reading of multiple realizability arguments, particularly in philosophy of psychology. (...)

  45. The “Multirealization” of Multiple Realizability.Holger Lyre - 2009 - In A. Hieke & H. Leitgeb (eds.), Reduction, Abstraction, Analysis. Ontos. pp. 79.
    Multiple Realizability (MR) must still be regarded as one of the principal arguments against type reductionist accounts of higher-order properties and their special laws. Against this I argue that there is no unique MR but rather a multitude of MR categories. In a slogan: MR is itself “multi-realized”. If this is true then we cannot expect one unique reductionist strategy against MR as an anti-reductionist argument. The main task is rather to develop a taxonomy of the wide variety of (...)

    Life-World, Sub-Worlds, After-Worlds: The Various ‘Realnesses’ of Multiple Realities.Ruth Ayaß - 2017 - Human Studies 40 (4):519-542.
    This paper will discuss the correlation between the world of everyday life, finite provinces of meaning, and religion. To this end, the paper will start out by explaining Schutz’ considerations on “paramount reality” of the world of everyday life as well as the theory of “multiple realities” and “finite provinces of meaning”. Schutz’ considerations will then be elaborated upon and taken a step further in a discussion of the various ‘realnesses’ of the multiple realities. Special attention will be (...)

    NO Revision and NO Contraction.Gregory Wheeler & Marco Alberti - 2011 - Minds and Machines 21 (3):411-430.
    One goal of normative multi-agent system theory is to formulate principles for normative system change that maintain the rule-like structure of norms and preserve links between norms and individual agent obligations. A central question raised by this problem is whether there is a framework for norm change that is at once specific enough to capture this rule-like behavior of norms, yet general enough to support a full battery of norm and obligation change operators. In this paper we propose an answer (...)

    Blockage Contraction.Sven Ove Hansson - 2013 - Journal of Philosophical Logic 42 (2):415-442.
    Blockage contraction is an operation of belief contraction that acts directly on the outcome set, i.e. the set of logically closed subsets of the original belief set K that are potential contraction outcomes. Blocking is represented by a binary relation on the outcome set. If a potential outcome X blocks another potential outcome Y, and X does not imply the sentence p to be contracted, then Y ≠ K ÷ p. The contraction outcome K ÷ p (...)

  49. Sequent Calculus in Natural Deduction Style.Sara Negri & Jan von Plato - 2001 - Journal of Symbolic Logic 66 (4):1803-1816.
    A sequent calculus is given in which the management of weakening and contraction is organized as in natural deduction. The latter has no explicit weakening or contraction, but vacuous and multiple discharges in rules that discharge assumptions. A comparison to natural deduction is given through translation of derivations between the two systems. It is proved that if a cut formula is never principal in a derivation leading to the right premiss of cut, it is a subformula of (...)

  50. Multiple Realizability.Ronald P. Endicott - 2005 - In D. Borchert (ed.), Encyclopedia of Philosophy, 2nd edition. Thomson Gale, Macmillan Reference.
    Multiple realizability has been at the heart of debates about whether the mind reduces to the brain, or whether the items of a special science reduce to the items of a physical science. I analyze the two central notions implied by the concept of multiple realizability: "multiplicity," otherwise known as property variability, and "realizability." Beginning with the latter, I distinguish three broad conceptual traditions. The Mathematical Tradition equates realization with a form of mapping between objects. Generally speaking, x (...)
