Darwin aficionados in Edinburgh say that if you want to get to grips with the intellectual growth of one of the world's most influential thinkers, you have to understand the timing. The young Darwin arrived in Scotland's capital city at a critical moment in its development, when Enlightenment ideas were bursting out in their rich final flowering.
John Scally, head of collections at Edinburgh University, says that Edinburgh in 1825was a city of almost unlimited potential, of scientific innovation and philosophical enquiry. The shadow of the sceptical David Hume loomed large; Sir Walter Scott was still in his pomp - Darwin even attended the Royal Society of Edinburgh when Scott himself was in the chair.
“We have one of the greatest intellectual fireworks displays that ever happened in Europe. And then one of the greatest minds which the UK ever produces happens to settle on it. You would expect something very important to happen,” Dr Scally said.
It's been a quiet January, but here's a handful of stories.
