Soil in the air

The post-war era of the 1940s is known for the birth of global governance, a time when Western nations united in efforts to reconstruct the war-torn world and reflected on the role of science in society. History and philosophy of science (HPS) was one of the early projects that emerged out of the war years. Diana (Ding) Dyason who headed the first HPS department in the southern hemisphere is honoured by this annual lecture, the text of which constitutes this article. Thomas Kuhn's influential lecture in Oxford in 1961 inspired her work on the history of scientific entanglement with social concerns, and the directions of HPS at the University of Melbourne. Post-war reconstruction was both a local and a national project for every nation, very much in the air in the 1940s, and influential until the 1970s. The Australasian Association of Scientific Workers (AASW) brought together scientists too old to serve, or, in reserved occupations, to undertake their own 'war effort' on the question of: 'What comes next?' AASW held a planning conference in Sydney in 1944 to 'formulate a policy on the organisation of science necessary to meet the demands of post-war Australia'. They set out to consider the role of the 'the scientific method' in the welfare of society. In particular, they recognised their existing international scientific networks and connections could become valuable for post-war collaborations between different sciences and different nations of benefit to Australia and the world. The idea of 'the environment' was one of many that emerged internationally in these 'world-minded' times, an idea that focused on the management of nature for the benefit of people using the scientific method. National Parks were a crucial discussion point, bringing together amateur naturalists and professional environmental managers of all sorts in discussions about landscape planning along with international comparative work on reserving places for wild animals and plants. This Dyason Lecture explores the emergence of 'integrated science', of science in the service of society, that later included natural resource management, big science, environmental science, earth systems science and climate science. It begins with the tragedy of the 'dirty thirties', when soil was in the air, and the scientific response to concerns about feeding the world.
