Beware the side of the brain that plumps for Trump | Letters

Janet Dube, Hazel Davies and Peter Emerson respond to a piece by George Monbiot on the psychology of voters' support

George Monbiot suggests we can see human values as clustering around two poles, extrinsic and intrinsic (To beat Trump, we need to know why Americans keep voting for him. Psychologists may have the answer, 29 January). There might be something more at play.

In 1980, physicist David Bohm wrote about explicate and implicate orders in reality. Before the advent of quantum theory, said Bohm's colleague and biographer, David Peat, science dealt with the order of space and time, separation and distance, mechanical force and effective cause, which Bohm called the explicate order. He posited a deeper order, more congruent with quantum theory and closer to our unconditioned thought. He called it the implicate or enfolded order.
