  2. On the Ternary Relation and Conditionality.Jc Beall, Ross Brady, J. Michael Dunn, A. P. Hazen, Edwin Mares, Robert K. Meyer, Graham Priest, Greg Restall, David Ripley, John Slaney & Richard Sylvan - 2012 - Journal of Philosophical Logic 41 (3):595 - 612.
    One of the most dominant approaches to semantics for relevant (and many paraconsistent) logics is the Routley-Meyer semantics involving a ternary relation on points. To some (many?), this ternary relation has seemed like a technical trick devoid of an intuitively appealing philosophical story that connects it up with conditionality in general. In this paper, we respond to this worry by providing three different philosophical accounts of the ternary relation that correspond to three conceptions of conditionality. We close by briefly discussing (...)

    Negation And Contradiction.Richard Routley Val Routley, Richard Sylvan & Richard Routley - 1985 - Revista Columbiana de Mathematicas:201 - 231.
    The problems of the meaning and function of negation are disentangled from ontological issues with which they have been long entangled. The question of the function of negation is the crucial issue separating relevant and paraconsistent logics from classical theories. The function is illuminated by considering the inferential role of contradictions, contradiction being parasitic on negation. Three basic modelings emerge: a cancellation model, which leads towards connexivism, an explosion model, appropriate to classical and intuitionistic theories, and a constraint model, which (...)

Exploring a broad range of world views, religions and philosophies, David W. Clowney and Patricia Mosto bring together insightful thoughts on the ethical issues arising in various areas of environmental concern.

  13. Transcendental Metaphysics: From Radical to Deep Plurallism [Sic].Richard Sylvan - 1997 - White Horse Press.
    Richard Sylvan died suddenly at the age of 60, when he had just completed this major text. But though this volume is the mature expression of one of our foremost modern philosophers, it remains, like all his work, pioneering, eclectic and controversial. Sylvan's theory of 'plurallism', the culmination of his life's work, is the subject of this important text. In his own characteristically provocative words, 'There is not merely a plurality of correct theories and more or less satisfactory worldviews: there (...)

    Da Costa's C systems are surveyed and motivated, and significant failings of the systems are indicated. Variations are then made on these systems in an attempt to surmount their defects and limitations. The main system to emerge from this effort, system CC , is investigated in some detail, and dual-intuitionistic semantical analyses are developed for it and surrounding systems.

    Answering Another Alleged Dilemma Destroying Dialetheism.Richard Sylvan & Graham Priest - 1988 - Bulletin of the Section of Logic 17 (1):42-48.
    To leave matters in no doubt, we obligingly assert that the Russell class R, i.e. {x : x 6∈ x}, both belongs to itself and also does not belong to itself; in short, we assert R ∈ R & ∼ . To be quite explicit, we assert the contradiction r & ∼ r, where r abbreviates R ∈ R. Thus, in convenient symbols, `δ r & ∼ r, where δ is the group of dialethicians comprising Priest and Routley.

    Strictly speaking, intuitionistic logic is not a modal logic. There are, after all, no modal operators in the language. It is a subsystem of classical logic, not [like modal logic] an extension of it. But...

    Re-explored are certain item-theory theses, major problem zones, and newer puzzles and, together therewith, prospects for liberalizing and pluralizing item-theory. Undoubtedly item-theory may be further liberalized, partly by further dissociation from object-theory and the restrictions object imposes, but primarily through substantial deregulation of the styles of characterisations permitted. Then almost anything goes; nonetheless what results is a sufficiently well-organised smooth-running sistological anarchism. Characterisation is dispersed through a federation of regions: only in old central city regions do the characterisation postulates of (...)

    The Importance of Nonexistent Objects and of Intensionality in Mathematics.Richard Sylvan - 2003 - Philosophia Mathematica 11 (1):20-52.
    In this article, extracted from his book Exploring Meinong's Jungle and Beyond, Sylvan argues that, contrary to widespread opinion, mathematics is not an extensional discipline and cannot be extensionalized without considerable damage. He argues that some of the insights of Meinong's theory of objects, and its modern development, item theory, should be applied to mathematics and that mathematical objects and structures should be treated as mind-independent, non-existent objects.

    Process and Action: Relevant Theory and Logics.Richard Sylvan - 1992 - Studia Logica 51 (3-4):379 - 437.
    Whileprocess andaction are fundamental notions, in ubiquitous use, they lack satisfactory logical treatment in two critical respects: in analyses of the fundamentals themselves and in logical development. For what treatment they have so far received, under classical systematisation, leaves significant lacunae and induces much paradox. A relevant logical relocation, carried through in detail here, removes such problems, and provides solid ground-work for a satisfactory treatment.Firstly, as to fundamentals: processes should be explicated, so it is argued, as certain sorts of (time) (...)

    Cause as an Implication.Richard Sylvan & Newton Costa - 1988 - Studia Logica 47 (4):413 - 428.
    An appropriately unprejudiced logical investigation of causation as a type of implication relation is undertaken. The implication delineated is bounded syntactically. The developing argument then leads to a very natural process analysis, which demonstrably captures the established syntactical features. Next relevantly-based semantics for the resulting logical theory are adduced, and requisite adequacy results delivered. At the end of the tour, further improvements are pointed out, and the attractive terrain beyond present developments is glimpsed.

    The proposed synthesis is set within general object-theory. The underlying idea of the synthesis is that the alternative worlds semantics — arrived at in pursuit of a universal semantics (a general semantics for all languages, including relevant ones) and, connectedly, as part of a comprehensive object-theory — be applied also in fundamental physics, most importantly to the matter of the origin, history, and physical features of the cosmos, but as well, again connectedly, elsewhere, in particular in the interpretation of quantum (...)

    Curry claims that the positive paradox principle, ` A ⊃ in his elementary statement presentation, ‘is valid in any normal interpretation’ . By previous definition, ‘an interpretation of a system S is a normal interpretation just when the proposition A is true when and only when ` A’ . But his argument to normal validity is interestingly, and relevantly, invalid.
