In this paper, I discuss the use made by Aristotle of the term “element” when dealing with the atomist theory of Leucippus and Democritus. My goal is to verify which aspects of the atomist theory play the role of elements according to the definitions of Aristotle, who seems to have certain expectations regarding what can be designated as elements in the strict sense. One of them is the possibility of reciprocal transformation, the so-called “generation of elements”, which is the chemical (...) aspect at the level of the simple bodies that makes change possible at the level of sense-perceived bodies. Furthermore, I evaluate whether it is possible to find and whether it is adequate to speak of the presence of the four elements – fire, air, water and earth – in the atomist doctrine. (shrink)

Some authors have talken about the problem of the future contingents Aristotle exposed in De Interpretatione IX. But most of them do not explain the role of that chapter in his own work. Last analysis always try to find a formal solution. And this is very significative because De Interpretatione is a treatise that belongs to the semantic of the Organon. In this article we show that: 1. The aim of the problem of future contigents is not only formal and (...) the frame of the Aristotle’s solution. 2. Its implication with others important concepts in his philosophy like “substance”, “truth” and “dialectics”. (shrink)

This article focusses on the generality of the entities involved in a geometric proof of the kind found in ancient Greek treatises: it shows that the standard modern translation of Greek mathematical propositions falsifies crucial syntactical elements, and employs an incorrect conception of the denotative letters in a Greek geometric proof; epigraphic evidence is adduced to show that these denotative letters are ‘letter-labels’. On this basis, the article explores the consequences of seeing that a Greek mathematical proposition is fully general, (...) and the ontological commitments underlying the stylistic practice. (shrink)
