Aristotle: Natural Science

Aristotle is said to have held that any kind of actual infinity is impossible. I argue that he was a finitist (or "potentialist") about _magnitude_, but not about _plurality_. He did not deny that there are, or can be, infinitely many things in actuality. If this is right, then it has implications for Aristotle's views about the metaphysics of parts and points.

On Zeno Beach there are infinitely many grains of sand, each half the size of the last. Supposing Aristotle denied the possibility of Zeno Beach, did he have a good argument for the denial? Three arguments, each of ancient origin, are examined: (1) the beach would be infinitely large; (2) the beach would be impossible to walk across; (3) the beach would contain a part equal to the whole, whereas parts must be lesser. It is attempted to show that none (...) of these arguments was Aristotle’s. Indeed, perhaps Aristotle’s finitism applied to magnitude only, not plurality. (shrink)

I explain what Aristotle means when, after puzzling about the matter of motion in incomplete animals (those without sight, smell, hearing), he suggests in De Anima III 11.433b31-434a5 that just as incomplete animals are moved indeterminately, desire and phantasia are present in those animals, but present indeterminately. I argue that self-motion and its directing faculties in incomplete animals differ in degree but not in kind from those of complete animals. I examine how an object of desire differs for an incomplete (...) animal. Using a comparison with Aristotle’s account of recollection, especially in unfavorable circumstances, I describe indeterminate self-motion. Finally, I discuss implications for our understanding of Aristotle’s accounts of the faculties of the soul and incomplete animals. (shrink)

A lot of scholarly attention has been given to Aristotle’s account of how and why animals are capable of moving themselves. But no one has focused on the question, whether self-change is possible in plants on Aristotle’s account. I first give some context and explain why this topic is worth exploring. I then turn to Aristotle’s conditions for self-change given in Physics VIII.4, where he argues that the natural motion of the elements does not count as self-motion. I apply those (...) conditions to natural change in plants. Then I explore the reasons for and consequences of Aristotle’s argument that plants are incapable of sensation. I argue that for Aristotle plants cannot possess the directing faculties for self-change, namely, desire and phantasia. My goal is to show why growth, metabolism, and reproduction in plants would not count as self-change for Aristotle, despite many of these natural changes appearing as autonomous as the analogous changes in animals. This sheds light on how, for Aristotle, self-change differs from natural change. (shrink)

This paper clarifies the way Aristotle uses generation to establish the priority of activity in time and in being. It opens by examining the concept of genetic priority. The argument for priority in beinghood has two parts. The first part is a synthetic argument that accomplishment is the primary kind of source, an argument based on the structure of generation. The second part engages three critical objections to the claim that activity could be an accomplishment: activity appears to lack its (...) own structure; activity is different in kind from the object it accomplishes; and activity is external to its accomplishment. Aristotle responds to these objections by analyzing the structure of generation. In the course of the argument, Aristotle establishes that beinghood and form are activity. (shrink)

The main aim of my paper is to analyse Aristotle’s theory of language in the context of his Physics I.1 and via an analysis and an interpretation of this part of his Physics I try to show that (i) the study of human language (logos) significantly falls within the competence of Aristotle’s physics (i.e. natural philosophy), (ii) we can find the results of such (physical) inquiry in Aristotle’s zoological writings, stated in the forms of the first principles, causes and elements (...) of the human speech (logos) and (iii) the analogies (Phys. 184b13-14) made by Aristotle at the very end of the first chapter make better sense if we consider them in the broader context in which Aristotle recognizes language as a complex natural phenomenon we are born into and which has to be not only biologically, but also socially developed through our lives. Hence, I aim towards a more naturalistic reading of Aristotle’s views on language. (shrink)

Originating from two conferences that took place in September 2013 and June 2015 at Sapienza University of Rome, this outstanding specialist volume aims to systematically illuminate the arguments that Aristotle uses in trying to establish the ‘first principles’ of his natural philosophy in Physics I. Not only is it successful in achieving this overall goal, but it is also timely, as its publication anticipates the forthcoming proceedings of the July 2014 Symposium Aristotelicum, devoted to the Physics.

It is well known that Aristotle tries to make room for self-motion – an idea he inherits to some extent from Plato – within his other commitments to causal determinism while at the same time modifying the idea. However, one argument in Physics VII 1 seems to pose a problem for the bare possibility of self-motion; in it he seems to argue that everything that moves must be moved by something else. The text in which this argument appears is itself (...) vexed on a number of fronts, because it is not clear how Physics VII fits with the rest of the Physics, and also because there are two distinct manuscript traditions for Physics VII. So the argument in Physics VII 1 has not been adequately taken into account in discussions of self-motion. I argue for a new and charitable reading of Aristotle’s Physics VII 1 α241b35-242a49 / β241b25-242a15. I show that the argument is compatible with Aristotle’s endorsements of self-motion; I defend the argument’s most controversial premise; and I argue that my reading has some useful implications for understanding Aristotelian self-motion.

In Physica I,8 Aristotle endeavors to show that a long-term Eleatic puzzle about coming-to-be can be resolved by appealing to his own ontological principles of change (substratum, privation, and form). In this paper, I posit that the key to Aristotle’s resolution lies in the introduction of aspectual distinctions within numerical unities. These distinctions within the terminus a quo and the terminus as quem of coming-to-be made it possible for Aristotle to maintain, while answering the puzzle, that there is no coming-to-be (...) ex nihilo and, at the same time, that the product of coming-to-be is something that did not exist before; i.e. that there is coming-to-be. Finally, I suggest that this resolution could be seen as an interesting case of the application of conceptual tools developed in the Sophistici Elenchi, and I analyze the advantages of this resolution over the Platonic resolution of a similar sort of Eleatic problem.

The purpose of this paper is to illustrate the role of some peculiar elements of Aristotle's dialectical development —namely, those emerging in the Sophistical Refutations (SE)— in the analysis and discussion of the Eleatic thesis in Physics I, 2-3. The paper adresses some of Aristotle's preliminary thoughts (Phys. I, 2) (which are read as methodological considerations), and some remarks against Melissus' argument (Phys. I, 3), in order to find connections between such claims and passages of SE, as well as the (...) Topics. -/- . (shrink)

In its early modern form, philosophy gave a decisive impetus to the science and technology that have transformed the planet and brought on the so-called Anthropocene. Can philosophy now help us understand this new age and act within it? The contributors to this volume take a broad historical view as they reflect on the responsibilities and possibilities for philosophy today.

In 1988 the philosopher Gilles Deleuze remarked that throughout his career he had always been 'circling around' a concept of nature. Showing how Deleuze weaves original readings of Plato, the Stoics, Aristotle, and Epicurus into some of his most famous arguments about event, difference, and problem, Michael James Bennett argues that these interpretations of ancient Greek physics provide vital clues for understanding Deleuze's own conception of nature. -/- "Deleuze and Ancient Greek Physics" delves into the original Greek and Latin texts (...) and situates Deleuze's interpretations in relation to contemporary scholarship on ancient philosophy. It reveals that these readings are both more complex and controversial than they may at first appear. Generating both new critical analyses of Deleuze and an appreciation for his classical erudition, this book will be a valuable resource for anyone interested in ancient Greek philosophy, Deleuze's philosophical project, or his unique methodology in the history of philosophy.

In a discussion-note in Mind, Father P. M. Farrell, O.P., gave an account, in what he admitted to be an embarrassingly brief compass, of the Thomist doctrine concerning evil. There is one sentence in this discussion which at first glance appears paradoxical. Father Farrell has been arguing that a universe containing ‘corruptible good’ as well as incorruptible is better than one containing ‘incorruptible good’ only. He continues: ‘If, however, they are to manifest this corruptible good, they must be corruptible and (...) they must sometimes corrupt.’ The final words, despite Father Farrell's italics, strike one as expressing, not a self-evident truth, but a non sequitur. The fact that I am capable of committing murder does not entail that I will at some time commit it. It is not immediately obvious that a similar entailment holds in the case of corruption and corruptibility. (shrink)

Sunaisthesis is a generally overlooked or misconstrued concept central to Aristotle’s philosophy of friendship, and therefore to his entire ethical and politicalproject. As opposed to Stoic uses that presuppose ethical self-relation, in Aristotle’s coinage, sunaisthesis indicates the genesis of a self-relation mediated through the friend. Both the “merged selves” and the “mirrored selves” approaches to Aristotelian friendship distort this peculiar mediation. Through a close reading of relevant texts, I show that sunaisthesis provides the missing link between the De Anima’s non-reflexive (...) perceiving self and Aristotle’s requirement of a robustly reflexive yet socially inculcated ethical self. Sunaisthesis accounts for ethical responsibility while reinforcing rather than denying our embodied and socially embedded nature. (shrink)

In protreptic passages in three Aristotelian texts, there is a close relationship betweenthe use of the language of thaumaston and that of timion. These texts exhibit a progressive opening of Aristotle’s students to further horizons of philosophical awareness, within which is embedded a global transformation of the meanings of thaumaston. They mark the itinerary of a spiritual formation in which a new relationship through language to phenomena and to others liberates the student from a psychology of emulation into a discipline (...) of radically free inquiry.
