Letter: Belief, diversity and evolution

Published 22 April 2015

From Peter Silverman

Lawton quotes psychologist Peter Halligan as saying: “The prime directive of the brain is to extract meaning. Everything else is a slave system.” The purpose of the brain is rather to take in data, process it and make decisions – with the objective of maximising the chance of passing on the animal’s genes.

Whether any meaning is or is not extracted in the process is a meaningless consideration.
