  1. Graham Priest's «Dialetheism» -- Is It Althogether True?Lorenzo Peña - 1996 - Sorites 7:28-56.
    Graham Priest's book In Contradiction is a bold defense of the existence of true contradictions. Although Priest's case is impressive, and many of his arguments are correct, his approach is not the only one allowing for true contradictions. As against Priest's, there is at least one contradictorialist approach which establishes a link between true contradictions and degrees of truth. All in all, such an alternative is more conservative, closer to mainstream analytical philosophy. The two approaches differ as regards the floodgate (...)

    Critical Notice of Subject, Thought and Context.Lorenzo Peña & Manuel Liz - unknown
    The main starting point of many of the contributions collected into the book is the kind of Twin Earth considerations, along with meaning individualism. Is Putnam's claim about water in this world and a stuff in an alternative world being different materials?. Is meaning in the head? One seems allowed to be skeptical about the starting point of the debate between such as emphasize broad content and those who think that the basic semantic entities are narrow contents, which would fail (...)

    De la logique combinatoire des 'Generales Inquisitiones' aux calculs combinatoires contemporains.Lorenzo Peña - 1991 - Theoria 6 (1/2):129-159.
    In his 1686 essay GI Leibniz undertook to reduce sentences to noun-phrases, truth to being. Such a reduction arose from his equating proof with conceptual analysis. Within limits Leibniz’s logical calculus provides a reasonable way of surmounting the dichotomy, thus allowing a reduction of hypothetical to categorical statements. However it yields the disastrous result that, whenever A is possible and so is B, there can be an entity being both A and B. Yet, Leibniz was in the GI the forerunner (...)

    Un Enfoque No-Clásico de Varias Antinomias Deónticas.Lorenzo Peña - 1987 - Theoria 3 (1):67-94.
    Three (apparent ) deontic antinomies are discussed: the paradoxes of the watchman and the praiser, as weIl as deontic dilemmas. A paraconsistent deontic logic, Ad, is put forward whose underlying 1st-order calculus is an infinite-valued tensorial logic. Several arguments are offered bearing out be existence of deontic contradictions, while two ways of dealing with conditional obligation paradoxes within the framework of Ad are canvassed. While the aggregation rule and the ought-implies-can principle are upheld, sundry schemata are shown not to obtain (...)

    Agregados, Sistemas Y Euerpos: Un Enfoque Difuso-Conjuntual.Lorenzo Peña - 1985 - Theoria 1 (1):159-175.
    A Fuzzy-Set Theoretical Framework -resting on a paraconsistent infinite-valued logic- is sketched, wherein a thorough ontological-reduction program can be carried out. The framework includes formulae of the form “x comprises z in the time-interval e”. Reducing aggregates to sets thus handled is shown to escape usual objections. Likewise, systems generally can be regarded as aggregates, hence as (fuzzy) sets -the purported nonextensionality of systems objection being disposed of owing to our system’s recognizing infinitely many membership degrees. So do bodies, too, (...)

    Algunas aplicaciones filosóficas de las lógicas multivalentes.Lorenzo Peña - 1992 - Theoria 7 (1/2/3):141-163.
    Many-Valued logics can harbour nonclassical connectives expressing truth-nuances. The course of development of many-valued logics has given rise to paraconsistent systems wherein a sentence can be both negated and asserted just in case it is only partly true. A recently implemented family of such logics is shown to be a useful tool in coping with a number of philosophical difficulties, such as Zeno’s paradox of the arrow. This family is somehow akin to fuzzy logics initiated by Zadeh, but unlike them (...)

    A comparative study of a broad range of logical systems, showing that classical logic is just one among them and thate there are useful nonclassical logics which are conservative extensions of classical logic, by risorting to several negations and several implications. The book is oriented towards a defense of fuzzy logics.

    Essence and Existence in Leibniz's Ontology.Lorenzo Pena - forthcoming - Synthesis Philosophica.
    The concept of every real thing from all eternity contains the unavoidability of its existence before the divine decision. Thus every complete concept of a real thing contains the property of being such that the thing will exist if a created universe exists. Then a thing's existence cannot be external to its concept. There is bound to be more in the concept of something that exists than in that of "something" that does not-since existence is explained through the quidditative property (...)

    Notes on Bergmann's New Ontology and Account of Relations.Lorenzo Peña - 1986 - Philosophy Research Archives 12:219-249.
    Recent work of Gustav Bergmann develops an ontological framework within which an account of relations has been sketched out. The approach is a kind of new logical atomism which has some of the features of an Aristotelian hylomorphism (of sorts). It recognizes a number of categories and groups of a hylomorphic kind, chiefly “determinates” and “subdeterminates”--the latter only indirectly or implicitly. Winsome though it is, the approach is flawed by certain difficulties it gives rise to, among them inability to speak (...)

    The paper goes into the intricate logical relation between imperatives, precepts and norms. It shows that there need not be two senses of "ought", the one descriptive and the other prescriptive, since when the law-giver enacts a fresh statute he is hereby making a tru statement, whose truth is grounded on the statement itself.
