One of the explicit objectives of Darwin's Descent of Man, and Selection in Relation to Sex was to explain cultural differences seen in human beings. Such an explanation, Darwin believed, was to rest upon an understanding of sexual selection. I examine the role that the beautiful plays within the mechanism of sexual selection as it works to differentiate isolated groups. It is suggested that an examination of the relationship between sexual selection and artificial selection — a relationship mediated by the (...) beautiful — will illuminate key issues of the Descent as well as contemporary debates regarding the relationship between evolution and ethics. The beautiful, originally rooted in sexual selection, can become de-coupled from sexual selection and utilized in some selective process which is conscious. (shrink)

This book provides a detailed analysis of Aristotle's Parts of Animals. It takes its bearings from the detailed natural history observations that inform, and in many ways penetrate, the philosophical argument. This analysis raises the question of how easy it is to clearly disentangle what some might describe as the "merely" biological from the philosophical. This book explores the notion and consequences of describing the activity in which Aristotle is engaged as philosophical biology. Do readers of Aristotle have in mind (...) organisms like sea squirts (ascidians) or sea cucumbers (holuthurians) when trying to understand Aristotle's argument regarding plant-like animals? Do we need the phenomena in front of us to understand the terms of the philosophical argument in a richer way? The discussion of plant-like animals is important to Aristotle because of the apparent continuum between plant and animal life. Where does Aristotle draw the line? Plant-like animals bring this question into focus and demonstrate the indeterminacy of any potential solution to the division. This analysis of the Parts of Animals shows that the study of the nature of the organic world was Aristotle's way into such ontological problems as the relationship between matter and form, the interplay between form and function, and the heterogeneity of the many different kinds of being.

In this paper, I speculate on imitation’s role in language development and, more significantly, on its connection to sexual selection. My analysis is grounded in an interpretation of Darwin’s Descent of Man . In addition to observing imitation’s role in language development according to the argument of the Descent , I explore the ability of human beings that allows for the imitation of both the beautiful and the terrible or repulsive. I suggest that humans, in their appreciation of the beautiful (...) and formidable characters produced by a process of sexual selection, can appropriate these things in order to adorn themselves, thus imitating other non-human animals. This capacity points to a form of polymorphism manifest in human beings that is grounded in a psychological fluidity. Human beings, like birds, also have the power to use song in order to charm and challenge. Song and music provide the means by which imitation as seen in language development and sexual selection are intertwined, thus providing the important connection between the two main foci of my paper.
