    Da Costa's paraconsistent systems of the series Cm (for finite m) (see [C1], [C2], and esp. [C3], pp. 237ff.) share important features with transitive logic, TL (which has been gone into in [P1] and [P2]), namely, they all coincide in that: (c1) they possess a strong negation, `¬', a conditional, `⊃', a conjunction, `∧', and a disjunction, `∨', with respect to which they are conservative extensions of CL or Classical Logic; (c2) they possess a non strong negation, `N' (notations are (...)

  3. Lorenzo Peña, Dialéctica, Dialéctica, Lógica Y Formalización: Formalización: De Hegel a la Filosofía Analítica.
    En este trabajo estudio algunas de las convergencias y divergencias entre dos concepciones filosóficas que coinciden en reconocer la contradictorialidad de lo real, o sea: que coinciden en ser dialécticas. Trátase de la filosofía de Hegel y de la concepción que en muy diversos trabajos y desde hace años vengo denominando ontofántica, concepción cuya aceptación de la contradictorialidad de lo real se sitúa más en la línea de Platón que en la de Hegel.

  4. Lorenzo Peña, Is Reasoning the Same as Relevant Inference?
    There are two main approaches to a theory of rationality: the positive one and the negative one. The latter, which has gained increasing acceptance, is primarily concerned with rejecting what is irrational, which usually is equated with what is inconsistent. The positive approach has a quite different purpose, that of studying reasoning and, insofar as possible, enhancing the patterns or standards of our reasoning practice.

  5. Lorenzo Peña, Leibniz on the Principle of Transition.
    Arthur Lovejoy's masterful, highly influential interpretation of Leibniz's philosophy has been almost neglected for decades now. This paper tries to rehabilitate Lovejoy's construal (with a number of adaptations) by delving into the underlying logical links connecting Leibniz's principles of order and gradation (the latter also called `law of continuity', `principle of transition' or `principle of the jumpless change': natura non facit saltus ) with other fundamental principles of his mature philosophy.

  6. Lorenzo Peña, Naturalized Epistemology and Degrees of Knowledge.
    Still, it is but fair for me to point out that several of the mainstays of the present proposal owe very little to the influence of the philosophers whose epistemological views have attracted me most — or for that matter to that of other analytical philosophers. I am referring to my acknowledging degrees of truth and existence and, consequently, degrees of knowledge, too.

  7. Lorenzo Peña, Phonology.
    Phonemes are minimal segments within the spoken message whose presence is relevant for distinguishing one message from a different one with another meaning. Each phoneme underlies different phonetic realizations. What sets a phoneme from another is fuzzy cluster of the fuzzy features. Thus the study of phonemic structures is likely to have much to gain from a gradualistic approach. Through a gradualistic treatment synchronic phonology could tally with the diachronic study in a simpler way than is customary. In this connection, (...)

  8. Lorenzo Peña, Philosophy Research Archives.
    This essay belongs to a series of papers whose aim is to show that some differing accounts of relations in contemporary philosophy (commencing with Frege) are flawed because they resort to what can be labelled `hylomorphism'. Some standard difficulties of Aristotelianism reappear in these analytical approaches. All of them resort to «form» as playing the role of `«ctualizing» a given «matter» (objects taken as arguments, relata, or a relation along with the related terms -- the form then being, e.g., (...)

  9. Lorenzo Peña, Sofia.
    The main claim of this paper is that the boundary between scientific and non scientific knowledge does exist -- which means several things. First, it's not the case that anything goes: some irrationalists have been mistaken into acceptance of that wrong conclusion because they have remarked that, however the boundary might be drawn, some important scientific developments would fall afoul of the standards entitling a research practice to count as scientific. Second, the boundary is not an imaginary one, that is (...)

Raúl Orayen is one of the outstanding analytical philosophers in the Spanish speaking world. As in his other publications, he displays a masterly reasoning power. No patched up solutions in this book. Orayen is not going to let what he takes to be unsatisfactory treatments off the hook with vague considerations of their being able to cope (...)

  11. Lorenzo Peña, To Be Delivered at the 3d Symposium Platonicum.
    It is widely known that Plato seems to be committed in a number of dialogues to the view that all perfections are “united” — whether such unity is construed as identity, which doesn’t lack textual evidence, or, more probably, as some kind of mutual “supervenience”. (See for instance Laches 199e3-4, Alcib. I 114d-116d, Protag. 329c-333d & 349a-c. Whatever the solution to those interpretive problems is, what anyway can be ascertained is that, when writing the Statesman, our philosopher is keen on (...)

    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 (...)

    While lawers and philosophers of law show the difference between matters of fact and normative situations, this paper proves that the difference is not crisp, since, in accordance with usual international private law, foreign juridical norms are, in principle, considered facts, but only up to a certain degree.

    This paper develops several insights put forward in the book Republican Studies. It goes into the difference between republicanism as a concept pertaining to legal theory, i.e. a system free from dynastic power, and the political-philosophy trend which currently goes by the same name, also known as `civicism', hinging upon the notion of freedom as non-domination. As against such a view, the value of a classical notion of liberty is maintained. Further grounds to choose a republic rather than a monarchy (...)

  16. Txetxu Ausín & Lorenzo Peña, Arguing From Facts to Duties.
    [EN] One of the most controversial issues about deontic and ethical matters is whether statements of duty or right can be inferred from statements of fact, and conversely. Most analytical philosophers have given a negative answer. We hold that there is a valid logical inferential rule from duties or permissions to facts, and conversely. Many duties and permissions arise only because certain facts exist. The reason is that a general principle of morals and law lays down that, if we act (...)

Still, in the same way as that famous example has served to buttress Putnam's dictum about meaning not being in the head, the example's weakness detract plausibility from that sort of considerations. Now in fact there are such weaknesses. If the aquatic stuff in Houto is quite similar to (...)

    The paper examines Beuchot's approach and agrees that there are many coincidences between medieval Aristotelianism and analytical philosophy. Both pursue philosophical inquiry in an argumentative manner. Nowadays analytical philosophy also tends to recognize as genuine such traditional metaphysical problems as were debated by the Scholastics. The paper's only criticism at Beuchot's views concerns analogy and reduplicative as-clauses. It argues that on that issue the cleavage between medieval and analytical philosophy lies in the latter's tending to favor complete equivocality of the (...)

    Es tarea de todos aplicar una ley, o sea realizar y ejecutar aquellos actos jurídicos y hechos prácticos que desembocan en su cumplimiento o lo constituyen. Se aplica una norma de carácter implicativo cuando, ante la existencia de un supuesto de hecho previsto en ella, se concluye la obligación contenida en su consecuencia jurídica, actuándose de conformidad con ello. Eso es incompatible con la separación de lo normativo y lo fáctico, propia del normativismo de Kelsen. Y es que hay situaciones (...)

Ha habido, a lo largo de la historia, progresos y retrocesos en la conciencia jurídica de los derechos migratorios. Hoy tienden a establecerse cláusulas de libre circulación en los espacios de integración económica, al paso que, de manera general , viene prohibida la inmigración del sur al norte. Esa orientación actual es injusta. Ni se atiene a un principio (...)

    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 (...)

Orayen regards Quine as his main interlocutor. The major topic gone into through the book is logical form, validity and logical truth. As an outgrowth, Quine's operationalist view of language receives an extensive coverage and discussion. The investigation into the notion of logical truth and validity leads to a critical assessment of the relevantist challenge to the (...)

    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 (...)
