Una teoría causal de la modalidad
ALVARADO,JOSé TOMáS;
Ideas y Valores , 2009,
Abstract: this work presents a causal conception of metaphysical modality in which a state of affairs is metaphysically possible if and only if it can be caused (in the past, the present or the future) by current entities. the conception is contrasted with what is called the "combinatorial" conception of modality, in which everything can coexist with anything else. this work explains how the notion of 'causality' should be construed in the causal theory, what difference exists between modalities thus defined from nomological modality, how accessibility relations between possible worlds should be interpreted, and what is the relation between the causal conception and the necessity of origin.
Universales estructurales
Alvarado, José Tomás;
Manuscrito , 2011, DOI: 10.1590/S0100-60452011000200003
Abstract: the work presents the concept of a structural universal and the criticisms that have been leveled against it. a structural universal is a property had by an individual due to the nature of its proper parts and due to the relations obtaining between those parts. mellor has argued that there is no reason to accept such universal in addition to the basic universals that compose them. david lewis has argued -on the other hand- that it has not been satisfactorily explained how universals are composed by other universals. the composition by which a structural universal is given cannot be a set-theoretical construction or a mereological sum. several proposals to explain the nature of structural universals are discussed. finally it is argued that a structural universal should be understood as a complexion of higher-order universals.
A Causal Theory of Modality
José Tomás Alvarado
Ideas y Valores , 2009,
Abstract: This work presents a causal conception of metaphysical modality in which a state of affairs is metaphysically possible if and only if it can be caused (in the past, the present or the future) by current entities. The conception is contrasted with what is called the “combinatorial” conception of modality, in which everything can co-exist with anything else. This work explains how the notion of ‘causality’ should be construed in the causal theory, what difference exists between modalities thus defined from nomological modality, how accessibility relations between possible worlds should be interpreted, and what is the relation between the causal conception and the necessity of origin.
Necesidad de origen e Identidad fundada; consideraciones críticas en torno al argumento de Forbes
José Tomás Alvarado
Revista Observaciones Filosóficas , 2008,
Abstract: the work presents and criticizes the argument developed by Graeme Forbes for the necessity of origin. In first place, the argument is studied in detail, considering in particular its presuppositions and the relation it has with the argument of Saul Kripke and Nathan Salmon for the same conclusion. In second place, the difficulties of Forbes’s argument are discussed, comparing it with the criticism by Teresa Robertson. It appears that it is (i) at best, inconclusive, and (ii) in the worst case, incoherent.
PROBLEMAS DE EPISTEMOLOGíA MODAL
ALVARADO MARAMBIO,JOSé TOMáS;
Discusiones Filosóficas , 2006,
Abstract: it seems obvious -or almost- that we do possess a great amount of modal knowledge. we know a lot about necessary facts obtaining in mathematics, and we also know a lot about the contingent character of "middle size dry goods", for example. the question is how to explain that knowledge. in particular, this work will discuss the impact that the dilemma posed by paul benacerraf in the mathematical case would have over modal statements, considering the conceptions about modal facts and possible worlds advanced by david lewis and saul kripke.
LA NOCIóN DE JUSTIFICACIóN A PRIORI
Alvarado Marambio,José Tomás;
Discusiones Filosóficas , 2008,
Abstract: this work tries to clarify the notion of a priori justification. first, it is contended that a priori justification should be identified with what appears after rational reflection of our higher cognitive capabilities upon certain content, concerning the truth value of the said propositional content. a priori justification characterised in this way should not be considered infallible, nor especially reliable, nor connected to the necessary, although it is contended that the specific modal content of a proposition seems to require a priori justification. finally, it is argued that the usual idea that all propositions a priori are analytic should be considered with special caution: there is no clear sense of analyticity to construe this common thesis. this in any way prevents a wide domain where a priori justification is required for the warrant of our judgements whether some concept is or is not applicable in different cases.
Espacio modal y universales estructurales máximos
Alvarado Marambio,José Tomás;
Estudios de Filosofía , 2010,
Abstract: this work considers the validity of the theory of possible worlds as maximal structural universals in relation with the known criticisms against actualist views on possible worlds. in a first part the modal conception based on universals is summarily exposed. then, the different difficulties are presented. two of those appear especially relevant for the modal theory defended here: (i) the confusion of different indiscernible possibilities, and (ii) the explanation of the nature of the representation of possibilities. after the examination of these difficulties, it is shown how the modal theory based on universals can answer both problems.
CONDICIONES DE IDENTIDAD PARA UNIVERSALES TRASCENDENTES
Alvarado Marambio,José Tomás;
Alpha (Osorno) , 2010, DOI: 10.4067/S0718-22012010000200003
Abstract: in this work it is argued that it is not incoherent to attribute conditions of identity founded on causal powers to transcendent universals. after explaining some crucial notions of metaphysics of properties, it is said how conditions of identity for properties have been differentiated between so called “abundant properties” and “sparse properties”.
El argumento de sustracción para universales trascendentes
Alvarado Marambio, José Tomás;
Kriterion: Revista de Filosofia , 2012, DOI: 10.1590/S0100-512X2012000100013
Abstract: this work presents the subtraction argument for transcendent universals, i.e., for universals that are not instantiated. the argument depends on two main premises: (i) the contingency of the different instantiations of a universal, and (ii) the ontological independence between these instantiations. by the first premise one can postulate metaphysically possible worlds where given instantiations of a universal are subtracted. one can consider, then, a possible world where only one object instantiates a universal. by the principle (ii) of independence, construed in a particular way, one can postulate in this point a possible world where no object instantiates the universal. it is contended that the independence thesis (ii) is too strong for the defender of immanent universal, who can construe it in a milder guise, compatible with the generic dependence of universals to having some or other instance.
Mundos posibles como universales estructurales máximos: Una conjetura ontológica
Alvarado Marambio,José Tomás;
An??lisis filos?3fico , 2007,
Abstract: the work presents the conjecture that possible worlds are maximal structural universals. first, the paper explains roughly the different actualist extant conceptions of possible worlds and the systematic problems they have to face. it is argued that the conjecture presented shows how all those different conceptions can be unified in a single simple theory. second, it is explained why the best alternative for the constitution of the modal space is a domain of transcendent universals. finally, some difficulties for the conception are briefly indicated. a definitive justification of the conjecture presented should consist mainly in tackling those difficulties.
