I am pleased and honoured to have been asked to give the first of the lectures in memory of Dr Leslie Cooper. I was especially moved by the thought that the invitation was made knowing that I should almost certainly choose Gaia as the topic of my lecture. I know that many of you, especially biologists, think that the Gaia hypothesis is either trivial and untestable or else a mere reiteration of conventional wisdom in poetic terms. Hardly a topic with which to commemorate Leslie Cooper's memory.
You will be relieved to know that although Gaia is the theme of my talk, I shall try not to be overly partisan or dogmatic. My objective is to use Gaia theory to illustrate a top-down approach to earth and life science and try to contrast it with the bottom-up approach which is conventional in the earth and life sciences.
