For delightfully quirky descriptions of bizarre neurological syndromes that teach us a lot about how the brain works, there is no match for Oliver Sacks.

I'm enormously interested to see where neuroscience can take us in understanding these complexities of the human brain and how it works, but I do think there may be limits in terms of what science can tell us about what does good and evil mean anyway, and what are those concepts about?

The brain is the most complicated organ in the universe. We have learned a lot about other human organs. We know how the heart pumps and how the kidney does what it does. To a certain degree, we have read the letters of the human genome. But the brain has 100 billion neurons. Each one of those has about 10,000 connections.

I think we're all fascinated and a little mystified by how the brain works. One of the most mysterious of the physical sciences is neurological science.

This is a stunning surprise, rather like finding out that the key to your house also works in the ignition of your car,
