Translation of Aristotle's Physics I-II into Portuguese, with commentaries. Tradução para o português dos livros I e II da Física de Aristóteles, com comentários.

This book investigates what change is, according to Aristotle, and how it affects his conception of being. Mark Sentesy argues that change leads Aristotle to develop first-order metaphysical concepts such as matter, potency, actuality, sources of being, and the teleology of emerging things. He shows that Aristotle’s distinctive ontological claim—that being is inescapably diverse in kind—is anchored in his argument for the existence of change. -/- Aristotle may be the only thinker to have given a noncircular definition of change. When (...) he gave this definition, arguing that change is real was a losing proposition. To show that it exists, he had to rework the way philosophers understood reality. His groundbreaking analysis of change has long been interpreted through a Platonist lens, however, in which being is conceived as unchanging. Offering a comprehensive reexamination of the relationship between change and being in Aristotle, Sentesy makes an important contribution to scholarship on Aristotle, ancient philosophy, the history and philosophy of science, and metaphysics.

For theological reasons, medieval thinkers maintained that sacraments “effect what they figure”—that is, they are more than mere signs of grace; and yet, they also maintained that they are not proper causes of grace in the way fire is the proper cause of heat. One way to reconcile these requirements is to explicate sacramental causation in terms of sine qua non causes, which were distinguished from accidental causes on the one hand, and from proper efficient causes on the other hand. (...) This article traces the development of this concept, as discussed in the context of the sacraments, from Scotus and Auriol, via Ockham and Peter of Ailly, to Gabriel Biel. It shows how the discussion, in its later stages, opened up concerns about occasionalism, offering thereby a case study of how particular theological issues led to metaphysical ones in the fourteenth and fifteenth centuries.

Like many realists about causation and causal powers, Aristotle uses the language of necessity when discussing causation, and he appears to think that by invoking necessity, he is clarifying the manner in which causes bring about or determine their effects. In so doing, he would appear to run afoul of Humean criticisms of the notion of a necessary connection between cause and effect. The claim that causes necessitate their effects may be understood—or attacked—in several ways, however, and so whether the (...) view or its criticism is tenable depends on how we understand the necessitation claim. In fact, Aristotelian efficient causation may be said to involve two distinct necessary connections: one is a relation between causes considered as potential, while the other relates them considered as active. That is, the claims that (1) what has the power to heat necessarily heats what has the power to be heated, and that (2) a particular flame which is actually under a pot necessarily heats it, both of which appear to be true for Aristotle, involve distinct notions of necessity. The latter kind of necessity is based on the facts, as Aristotle sees them, about change, whereas the former is based in the nature of properties. Though different, both kinds of necessity are instances of what contemporary philosophers would call metaphysical necessity, and together they also amount to a theory of causal determination.

“Chance as a Positive Space of Indetermination in the Thomistic Assimilation of Aristotle’s Physics”. This article analyzes Thomas Aquinas’s assimilation of the Aristotelian theory of chance. The analysis highlights Thomas Aquinas’s unequivocal acceptance of Aristotelian philosophy, as well as the issues regarding which he abandoned the Aristotelian position by offering a new interpretation related to the role of chance in the context of the created cosmos. All in all, the confluence of these two great systems of thought –Aristotelian thought and (...) late Medieval Christianity– provided new ways to understand nature, by expanding the scope of physics from the absolutely determined to the anomalous and irregular.

I offer a new analysis of Aristotle's concept of an accidental cause. Using passages fromMetaphysics Δ and Ε, as well as Physics II, I argue that accidental causes are causally inert. After defending this reading against some objections, I draw some conclusions about Aristotle's basic understanding of causation.

Este artículo presenta una interpretación de dos discutidos pasajes de Metafísica VI 3 y XI 8 en los que se encuentra la argumentación de Aristóteles encaminada a evitar la necesidad universal con base en la existencia de las coincidencias. Esta argumentación ha suscitado múltiples e incompatibles interpretaciones desde la Antigüedad hasta nuestros días. En ellas se ha presentado la argumentación del Estagirita en un abanico que va desde comprenderla como una postura compatible con el más fuerte determinismo, hasta una que (...) requiere un muy generalizado indeterminismo. En diálogo con estas interpretaciones, se defenderá una lectura según la cual estos pasajes están diseñados para argumentar no contra el determinismo causal sino contra la predeterminación. (shrink)
