I present two logical systems to show the “analogy of proportionality„ common to several interpretations: modality (necessity and possibility), quantification, truth-functional relations, moral attitudes (deontic logic), states of knowledge (epistemic logic), and states of belief (doxastic logic). To display the two underlying analogical relations, I call upon the originally Scholastic convention, recently put to use again, of using squares, hexagons, and octagons “of opposition„. A combined epistemic–deontic logic happens to be found in the traditional “probabilist„ theory of the “good conscience„, (...) and I shall then briefly explain how this is so. (shrink)

Probabilism is a Scholastic discussion of conscience beginning in the sixteenth century and lasting over four hundred years. To tackle historical issues in normative ethics, the participants had to work out a general "metaethical" theory relating epistemic and deontic logics, the logics of knowledge and virtue. May I act if I am unsure that I may? How, when I am in doubt, can I acquire the critical mass of rationality that virtue demands? The normative aspect of the controversy has been (...) studied in its historical setting, but its interesting and original metaethics has been largely ignored outside the Scholastic circle itself. The discussion is obviously relevant, even practical, today; in fact, any treatment of conscience and relativism already includes the material of probabilist analyses. (shrink)

Edith Stein, an outstanding representative of the Catholic intellectual renaissance of the first half of the last century, was a “charter” member of the phenomenological school around Edmund Husserl and made key contributions to the renewed study of St. Thomas Aquinas. From a Jewish background, she entered the Catholic church and then the Carmelite order; when asked why she became a Catholic she would reply in Latin “secretum meum mihi”. I suggest, using her characteristic concepts such as “being objective” and (...) “undergoing”, why she wished to “fuse” phenomenology and Thomism as well as how she defined the moral “weight” of daily circumstances and how she combined epistemology with Carmelite mysticism. Then with the help of St. John of the Cross, I offer an explanation of her “secret”. Finally I describe her history of recent philosophy. (shrink)

I describe a “logic of creating” inspired by the “existential” argument of the existence of God in St. Thomas Aquinas’s De Ente et Essentia. suggest a modal reading of his reasoning based upon states-of-affairs said to be actual, contingent, necessary and the like. I take “creating” as teasing actuality out of possibility. After explaining the modal logic that I am assuming and relating it to Christian understandings of meaning and being, I present my modal interpretation, contrasting it with the views (...) of three modern philosophers. In an appendix I will analyze the text of St. Thomas’s existential proof. (shrink)

St. Thomas Aquinas has been considered a kairos in intellectual history for seeing God’s essence as being. Martin Heidegger criticized philosophers forrepresenting being as a be-ing and identifying it with God, and Jean-Luc Marion speaks of “God without being.” In her Potency and Act Edith Stein introduced thecategory of being without essence, but such being is not God but “the opposite.” For St. Augustine sin was an approach to nonbeing, and Stein saw it leading to a“displacement into nonbeing,” to an (...) “annihilation” where only a “null being” is retained. This eschatological reflection is an intriguing aspect of her “fusion” ofscholasticism and phenomenology. (shrink)

I wish to reflect briefly on what logic “is” and what the “is” is founded upon. Logic has traditionally been linked with argumentation. I shall examine a simple argument relative to a “miniworld”, and with the help of current logic and traditional ontology, extract from it a modest theory of logical entities and relations. “Current logic” involves modal semantics and the “traditional ontology” is that of Plato, Bonaventure and Thomas Aquinas, and some later philosophers.

En este texto el A. se propone mostrar que es posible emplear algunas técnicas de la lógica modal para reflexionar en torno al problema de la existencia de Dios. En la primera parte se presenta la estructura general de la lógica modal,su simbología y los diversos sistemas que recientemente han sido propuestos. En la segunda parte, el A. sugiere la posibilidad de formular en términos modales la prueba ontológica de San Anselmo. El texto culmina extrayendo algunas consecuencias de esta formulación.

La lógica deóntica. "la lógica de la ética", es aplicable a varias teorías morales, por ejemplo a las fundamentadas en la concepción de la virtud o en la del deber. Un "cuadrado de oposición" al estilo escolástico puede servir para exhibir las relaciones lógicas entre tales nociones morales u "operadores" como debe y puede. El sistema puede construirse sobre la base de un solo operador y luego otros pueden agregarse para indicar una correspondencia con otras expresiones del lenguaje ordinario. Se (...) ofrecen dos principios para aclarar la super erogación.el caso del acto o hábito bueno no obligatorio. y para proponer una lógica básica de la virtud. (shrink)

En los siglos XVI y XVII los lógicos hispanos e hispanoamericanos trabajaron con una compleja "teoría de los tipos" para explicar las diversas clases de entidades denotadas o significadas en el lenguaje. A. de la Vera Cruz y sus colegas plantearon un sistema lógico de muchas clases donde las sentencias generales eran reducibles a hileras de entidades cuyos términos referían a cosas singulares, el mismo que les permitió un análisis semántico básico. A. Rubio,asimismo, desarrolló una teoría del lenguaje científico y (...) la aplicó a la lógica misma, definiendo las proposiciones de la lógica como atribuciones de un segundo orden mental, propiedades relativas a contenidos de primer orden, atribuibles ellos mismos a objetos singulares.

This book attempts to advance Donald Griffin's vision of the "final, crowning chapter of the Darwinian revolution" by developing a philosophy for the science of animal consciousness. It advocates a Darwinian bottom-up approach that treats consciousness as a complex, evolved, and multidimensional phenomenon in nature rather than a mysterious all-or-nothing property immune to the tools of science and restricted to a single species. -/- The so-called emergence of a science of consciousness in the 1990s has at best been a science (...) of human consciousness. This book aims to advance a true Darwinian science of consciousness in which its evolutionary origin, function, and phylogenetic diversity are moved from the field’s periphery to its very centre, thus enabling us to integrate consciousness into an evolutionary view of life. Accordingly, this book has two objectives: (i) to argue for the need and possibility of an evolutionary bottom-up approach that addresses the problem of consciousness in terms of the evolutionary origins of a new ecological lifestyle that made consciousness worth having and (ii) to articulate a thesis and beginnings of a theory of the place of consciousness as a complex evolved phenomenon in nature that can help us to answer the question of what it is like to be a bat, an octopus, or a crow. -/- A Philosophy for the Science of Animal Consciousness will appeal to researchers and advanced students interested in advancing our understanding of animal minds as well as anyone with a keen interest in how we can develop a science of animal consciousness.

Animal welfare has a long history of disregard. While in recent decades the study of animal welfare has become a scientific discipline of its own, the difficulty of measuring animal welfare can still be vastly underestimated. There are three primary theories, or perspectives, on animal welfare - biological functioning, natural living and affective state. These come with their own diverse methods of measurement, each providing a limited perspective on an aspect of welfare. This paper describes a perspectival pluralist account of (...) animal welfare, in which all three theoretical perspectives and their multiple measures are necessary to understand this complex phenomenon and provide a full picture of animal welfare. This in turn will offer us a better understanding of perspectivism and pluralism itself. (shrink)

This book provides both an introduction to the philosophy of scientific modeling and a contribution to the discussion and clarification of two recent philosophical conceptions of models: artifactualism and fictionalism. These can be viewed as different stances concerning the standard representationalist account of scientific models. By better understanding these two alternative views, readers will gain a deeper insight into what a model is as well as how models function in different sciences. Fictionalism has been a traditional epistemological stance related to (...) antirealist construals of laws and theories, such as instrumentalism and inferentialism. By contrast, the more recent fictional view of models holds that scientific models must be conceived of as the same kind of entities as literary characters and places. This approach is essentially an answer to the ontological question concerning the nature of models, which in principle is not incompatible with a representationalist account of the function of models. The artifactual view of models is an approach according to which scientific models are epistemic artifacts, whose main function is not to represent the phenomena but rather to provide epistemic access to them. It can be conceived of as a non-representationalist and pragmatic account of modeling, which does not intend to focus on the ontology of models but rather on the ways they are built and used for different purposes. The different essays address questions such as the artifactual view of idealization, the use of information theory to elucidate the concepts of abstraction and idealization, the deidealization of models, the nature of scientific fictions, the structural account of representation and the ontological status of structures, the role of surrogative reasoning with models, and the use of models for explaining and predicting physical phenomena.
