One night in the 1920s botanist Arthur Tansley had an unsettling nightmare that involved him shooting his wife. So he did the natural thing and started reading the works of Sigmund Freud, and even went to be analysed by Freud himself. Then Tansley came up with an extraordinary theory. He took Freud's idea that the human brain is like an electrical machine – a network around which energy flowed – and argued that the same thing was true in nature. That underneath the bewildering complexity of the natural world were interconnected systems around which energy also flowed. He coined a name for them. He called them ecosystems. But Tansley went further. He said that the world was composed at every level of systems, and what's more, all these systems had a natural desire to stabilise themselves. He grandly called it "the great universal law of equilibrium". Everything, he wrote, from the human mind to nature to even human societies – all are tending towards a natural state of equilibrium. Tansley admitted he had no real evidence for this. And what he was really doing was taking an engineering concept of systems and networks and projecting it on to the natural world, turning nature into a machine. But the idea, and the term "ecosystem", stuck.
