The human factor

Guardian UK Book Review: After 40 years of studying the problem of consciousness, Nicholas Humphrey believes it was natural selection that gave us souls. God, he insists, had nothing to do with it.

The distance between a neurone and a human mind seems very great, and to many philosophers and scientists quite impossible for science to cross. Even if minds are made from brains, and brains are made from billions of neurones, there seems no way to get from one sort of thing to the other.

Nicholas Humphrey's whole life as a scientist has been spent on that journey: in the 1960s he was part of the first team to discover how to record the activity of single neurones in a monkey's visual cortex; nearly 40 years later, he has reached a grand theory of how consciousness might have arisen in a Darwinian world, and why it might give us reasons to live.

...The theory is, like every other theory of consciousness, extremely controversial. After 200 years in which science has appeared to dethrone God and deny the possibility of the soul, Humphrey is the first man to claim that science can agree that we have souls - but that it was natural selection, not God, which gave us them.
