This chapter addresses an interpretive question about why Aristotle identifies generation, growth and nourishment as the three distinct functions or activities of nutritive soul. Scholars typically try to explain this by appealing to the shared goal of these activities, though there is no consensus about what that goal is: Does Aristotle think that generation is a way of keeping oneself alive (and thus that the shared goal is self-maintenance), or is nourishment really a quasi-generative activity (and thus that the shared (...) goal is “form (re)production”)? Rather than taking that approach, Gelber offers a different but complementary way of accounting for the unity of these activities, by focussing on the continuity of their shared physiological basis. As it is argued here, the fact that these biological processes form a continuous cycle stems from Aristotle’s adherence, in his biological theory, to principles from his hylomorphic metaphysics. Attending to the details in works such as Generation of Animals that focus on the mechanisms underlying generation, growth and nourishment, it is shown how we can construct a coherent account of the unity of the three nutritive soul activities.

This chapter is an examination of the way aporiai are employed in Aristotle’s scientific account of animal reproduction, and how they are resolved. I argue that – surprising as it may be, given what Aristotle says in Metaphysics B about the importance of going through aporiai – there seems to be nothing of much significance about his use of them, at least if we assume that genuine cases of aporiai are being tracked by use of aporia-language. I demonstrate this negative (...) thesis by systematically going through the examples. There seems to be no common purpose for which they are raised, they have no single type of structure, and they are not caused by any one sort of difficulty. (shrink)

Was Aristotle the ‘father’ and founder of the epigenesis doctrine? Historically, I will argue, this question must be answered with ‘no’. Aristotle did not initiate and had no access to a debate that described itself in terms of ‘epigenesis’ and ‘preformation’, and thus cannot be considered the ‘father’ or founder of the epigenesis-preformation controversy in a literal sense. But many ancient accounts of reproduction and embryological development contain analogies to what early modern scientist called ‘epigenesis’ and ‘preformation’, and, in this (...) analogous sense, Aristotle can be considered a precursor of the epigenesis-preformation controversy. But is Aristotle’s position actually epigenetic, as most of the traditional interpreters hold, or preformationist, as some of the recent scholars believe? I will argue against the one-sidedness of both readings that Aristotle’s account of reproduction and heredity contains mainly epigenetic, but also a few preformationist characteristics. Whereas, for instance, Aristotle’s idea of a successive development of the embryo’s parts is doubtlessly epigenetic, Aristotle’s idea that the development of the embryo is an actualization and enlargement of potential parts, which are simultaneously present in the semen, can be considered a preformationist feature.

There are two different notions of seed at work in the Generation of Animals: seed as the spermatic residue, which concerns only the male and the female generative contributions, and seed as the kuêma and first mixture of the two generative contributions. The latter is a notion of seed common to plants and animals. The passage in GA I.18, 724b12–22 where Aristotle distinguishes between these two notions of seed has been mistakenly discredited as inauthentic or simply as irrelevant for understanding (...) the seeds of animals. On the other hand, recent studies have rather focused on the seed as spermatic residue, paying little attention to the notion of seed as kuêma. In this paper I defend the authenticity and relevance of this passage and show how understanding the notion of seed as kuêma is essential to have a complete picture of Aristotle’s account of seed. This common notion of seed makes sense of Aristotle’s otherwise puzzling use of the word “sperma” to designate the seeds of plants, the kuêma, the fertilized eggs, and the first mixture of the two generative contributions. It also proves helpful in determining what the word ‘sperma’ stands for in key passages, such as Metaph. IX.7. (shrink)

This paper argues that focusing on Aristotle’s theory of generation as primarily ‘hylomorphic’ can lead to difficulties. This is especially evident when interpreting the association between the male and sentient soul at GA 2.5. If the focus is on the male’s contribution as form and the female’s as matter, then soul becomes divided into nutritive from female and sentient from male which makes little sense in Aristotle’s biological ontology. In contrast, by seeing Aristotle’s theory as ‘archēkinētic’, a process initiated by (...) the male, the development of nutritive and sentient capacities emerges as intertwined, neither capacity originating in only one sex.
