Aristotle: History of Animals

Although there is much scholarship on Aristotle’s account of friendship (φιλία), almost all of it has focused on inter-personal relationships between human animals. Nonetheless, in both Aristotle’s ethical and zoological writings, he documents the intra- and inter-species friendship between many kinds of animals, including between human and non-human animals. Such non-human animal friendships establish both an indirect basis for establishing moral ties between humans and non-human animals (insofar as we respect their capacity to love and befriend others) and a direct (...) basis for establishing such ties (insofar as Aristotle provides a framework for thinking about utility and pleasure friendships between human and non-human animals). My paper defends Aristotle’s limitation of inter-species friendships to only utility and pleasure friendships and responds to scholars who claim that Aristotle recognizes no moral ties between human and non-human animals.

Aristotle thought that the albumen of bird’s eggs was hotter than the yolk. As he was convinced that the principle of life is located in the hotter substance, he located the proto-heart, not in the germinal disc near the surface of the yolk, but in the albumen. The early modern biologists Aldrovandi, Coiter, and Harvey, blinded the albumen. The early modern biologists Aldrovandi, Coiter, and Harvey, blinded by the halo effect, tried to explain away this mistake by overinterpretation, thus creating (...) or contributing to the creation of an availability cascade which has rendered Aristotle’s mistake invisible to most Aristotelian scholars.

Aristotle’s theory of spontaneous generation offers many puzzles to those who wish to understand his theory both within the context of his biology and within the context of his more general philosophy of nature. In this paper, I approach the difficult and vague elements of Aristotle’s account of spontaneous generation not as weaknesses, but as opportunities for an interesting glimpse into the thought of an early scientist struggling to reconcile evidence and theory. The paper has two goals: to give as (...) charitable and full an account as possible of what Aristotle’s theory of spontaneous generation was, and to examine some of its consequences; and to reflect on Aristotle as a scientist, and what his comments reveal about how he approached a difficult problem. In particular, I propose that the well-recognized problem of the incompatibility between Aristotle’s concept of spontaneity and his theory of spontaneous generation presents an opportunity for insight into his scientific methodology when approaching ill-understood phenomena.

: In Parts of Animals II.10, 655b37-656a8, Aristotle tacitly identifies a group of animals which partake of “ living only”. This paper is an attempt to understand the nature of this group. It is argued that it is possible to make sense of this designation if we consider that some animals, which are solely endowed with the contact senses, do nothing more than mere immediate nutrition by their perceptive nature and have no other action. It is concluded that some of (...) Aristotle ’s merely living animals would be certain kinds of sponge, certain sea anemones and the ascidians among testacea. (shrink)

A considerable number of the thirteenth and early fourteenth-century manuscripts of Michael Scot's Arabic-Latin translation of Aristotle's De animalibus display a system of guiding marginal glosses. These glosses are usually added by a later hand with respect to the hand that had written the text. The manuscripts were not only annotated for personal use, but also so as to allow for a better use in compiling commentaries, encyclopaedias and compendia. We can say that the marginalia form the main, if not (...) only, key to our understanding today of the use that readers made of the text. Apart from offering a mere explanation of the contents, we can see that their interest in the text was chiefly related to biblical exegesis and to scientific and medical knowledge. The approach to the text was often allegorical and moralizing in character. Some remarks reflect the reader's own experience and associations in relation to the text. (shrink)
