Morality, Nature, and Evolution

Evolutionary theory is often taken to paint a rather bleak picture of nature, depicting it as an aggressively competitive arena, “red in tooth and claw”, in which organisms are pitted against each other in a battle for survival of the fittest. Morality, on the other hand, seems centred on benevolence, cooperation and other kinds of altruistic behaviour that promote the survival of the unfittest. This might be taken to generate a puzzle: Where does morality, with its emphasis on helping those less fit, belong in the seemingly amoral economy of an environment hospitable only to the fit? The course begins by exploring Darwin’s solution to this puzzle, which centres on the idea that our moral sense is itself a product of evolution, designed to foster social instincts and thereby to promote the interests of the group. Subsequent lectures introduce more recent elaborations of this idea by contemporary thinkers and examine some of the central debates within the evolutionary science of morality. Along the way, various empirical studies involving humans and non-human animals are considered, and their implications are carefully analysed. Our focus then turns to wider questions about the philosophical implications of evolutionary science for politics, ethics, and metaethics. We ask, for instance, whether an evolutionary understanding of human nature yields particular views about moral rightness, about the fairness of free markets, and about the power relations between the sexes. On the metaethical side, we explore the ways in which an evolutionary understanding of morality bears on issues to do with the nature of moral judgments and the existence of objective moral truths.

Preliminary Reading:

•Richard Joyce, The Evolution of Morality (MIT Press, 2006).

Lectures:The lectures for this module will be held in xxx, on Mondays from 2 to 3pm in the Spring Term. The lecturer is Dr. Cristian Constantinescu ().

Seminars:The seminarsfor this module will be held on Mondays from 3 to 4pm in the Spring Term, as follows: BA seminars will be held by xxx in Room xxx; MA seminars will be held by Cristian Constantinescu in Room xxx.

Readings: Every week there is one key reading that is the focus of the seminar discussion. One of the purposes of the seminar is to help you to understand the reading, so do not worry if you have not fully understood the reading in advance. Nevertheless, it is essential that you attempt the seminar reading each week if you are to follow the lecture and to participate in the seminar discussion. In addition, there is ‘additional reading’ listed that will deepen your understanding and help you to get the most out of the module. You are especially advised to cover the additional reading for those topics on which you are planning to write.

Essays (BA): This module is assessed by one essay of around 3,000 words (maximum 3,200 words). It must be written in response to one of the set questions listed below, except with permission from the module convenor. The deadline for submission is xxx 2016. For details concerning submission of the essay see the BA Handbook.Prior to this assessed essay, you may also write up to two essays during the course, taken from the titles below, and receive feedback on them from your seminar leader. These can be useful practice for your eventual assessed essay. You should submit the first such essay by the first seminar after reading week, and the second by one week after the last seminar of term. [Notes: 1) You are always welcome to submit an essay earlier than these dates; 2) the seminar leader should not be expected to comment on the same essay more than once.]

Essay (MA): Students doing the new MA degree will be assessed by one essay of around 3,500 words (max. 3,700 words). It must be written in response to one of the set questions listed below, except with permission from the module convenor. The deadline for submission is xxx.

Students doing the old MA degree will be assessed by two essays of 2,750 words at most. They may have a tutorial on a draft of one essay, to be submitted by the first Monday of Term 2. No mark is given for these drafts. The deadline for submitting the two essays is xxx.
