Environmental Values
We can't just read off from the evolutionary story how we, as enculturated beings, should live, but the evolutionary story does present a starting point for how we need to think about ethics. Owen Flanagan presents a clear statement of this in his 'principle of minimal psychological realism' which states: 'make sure when constructing a moral theory or projecting a moral ideal that the character, decision processing, and behaviour prescribed are possible, or are perceived to be possible for creatures like us'.1 This suggestion is not altogether new; we can look back to Aristotle and Hume for some interesting insights about the nature of ethics being drawn from the nature of human beings, as this was understood in their respective times. And, of course, there are Darwin's own insights into these matters. The first two papers in this issue of the journal present a careful working through of specific ideas in Darwin's work, as they are presented by Darwin (rather than as they are often assumed to be), in order to develop an environmental ethic that recognises the role of humans as moral agents.
Robert Kirkman in his 'Darwinian Humanism' presents an account that blends a Kantian humanism, usually associated with a transcendental freedom, with a form of empiricist naturalism to forge an approach to ethics that fits both our experience of freedom and our experience of being intertwined with the world. Ben Dixon in 'Darwinism and Human Dignity' mines Darwin's work on conscience and then takes his ideas further by showing how conscience operates at the social level by enshrining the reflective products of conscience in the institutions we create.
As these authors show, Darwin's writings offer a rich source of insights that need not lead to a brutish form of sociobiology. Taking Flanagan's principle to heart, we can call on the plethora of information that is mounting from other academic fields that is relevant to ethical thinking. If we want ethics to have a bearing on how we live, what motivates us and, in the environmental field particularly, how to inspire the motivation to live in more environmentally conscious ways, then it makes sense to start with the reality of our situation: that we are evolved social animals, shaped by our contexts. To gain insights into how this evolutionary history and these social pressures have shaped and are shaping us we would do well to consult colleagues in other fields like anthropology, developmental and social psychology, cognitive science and neurobiology. This doesn't mean that normative ethics, as usually construed, drops out of the picture. It does mean that normative ethics can become more theoretically and practically powerful precisely because it is now proceeding on a more realistic basis.
