By defending the following views – that Aristotle identifies the generator and perhaps the obstacle remover as an essential cause of the natural sublunary elemental motion in Physics VIII 4; that this view is consistent with the view of Physics II 1 that the sublunary simple bodies have a principle of internal motion; and that the sublunary and the celestial elements have a nature in the very same way – I shall offer what has so far eluded Aristotelian commentators: a (...) consistent interpretation of Aristotle's theory of the natural motions of the sublunary and also the celestial elements.

I discuss an argument for the monistic idea that the cosmos is the one and only fundamental thing, drawing on the idea that the cosmos is the one and only thing that evolves by the fundamental laws.

Aristotle's claim that natural slaves do not possess autonomous rationality (Pol. 1.5, 1254b20-23) cannot plausibly be interpreted in an unrestricted sense, since this would conflict with what Aristotle knew about non-Greek societies. Aristotle's argument requires only a lack of autonomous practical rationality. An impairment of the capacity for integrated practical deliberation, resulting from an environmentally induced excess or deficiency in thumos (Pol. 7.7, 1327b18-31), would be sufficient to make natural slaves incapable of eudaimonia without being obtrusively implausible relative to what (...) Aristotle is likely to have believed about non-Greeks. Since Aristotle seems to have believed that the existence of people who can be enslaved without injustice is a hypothetical necessity, if those capable oí eudaimonia are to achieve it, the existence of natural slaves has implications for our understanding of Aristotle's natural teleology.

_ Source: _Volume 60, Issue 1, pp 88 - 126 The dominant interpretation of Metaphysics Θ.8 commits Aristotle to the claim that the heavenly bodies’ eternal movements are not the exercises of capacities. Against this, I argue that these movements are the result of necessarily exercised capacities. I clarify what it is for a heavenly body to possess a nature and argue that a body’s nature cannot be a final cause unless the natural body possesses capacities that are exercised for (...) the sake of its nature qua form. This discussion yields a better understanding of what capacities are, what explanatory work capacities do, and what it is to possess a nature. (shrink)

Más allá de las críticas de Aristóteles a la noción platónica de participación, existen algunos usos de este término que merecen ser atendidos en la obra aristotélica, en tanto suponen no solo una herencia platónica sino también una resignificación en un plexo conceptual diverso. Este trabajo explora el uso aristotélico de la noción de participación como finalidad no intencional en el argumento que sostiene que uno de los modos de alcanzar la inmortalidad es la procreación, para mostrar cómo se puede (...) compatibilizar la adopción de la terminología platónica de la participación con el entramado causal aristotélico.

This dissertation explores Aristotle’s use of teleology as a principle of explanation, especially as it is used in the natural treatises. Its main purposes are, first, to determine the function, structure, and explanatory power of teleological explanations in four of Aristotle’s natural treatises, that is, in Physica (book II), De Anima, De Partibus Animalium (including the practice in books II-IV), and De Caelo (book II). Its second purpose is to confront these findings about Aristotle’s practice in the natural treatises with (...) the theoretical picture of the structure of teleological explanations gained from Aristotle’s theory of scientific demonstration. For this purpose a new interpretation of Analytica Posteriora II.11 is presented. This study thereby contributes to recent scholarship on the relation between Aristotle’s philosophy of science and his philosophy of nature, while at the same time adding to our knowledge of Aristotle’s notion of teleology in terms of its explanatory merits and limits.
