“Raptional Optimist” Matt Ridley is likely to concur with many of the findings from this Daily Telegraph article.

Judging the world through headlines is like judging a city by spending a night in A&E – you only see the worst problems. This may have felt like the year of Ebola and Isil but in fact, objectively, 2014 has probably been the best year in history. Take war, for example – our lives now are more peaceful than at any time known to the human species. Archaeologists believe that 15 per cent of early mankind met a violent death, a ratio not even matched by the last two world wars. Since they ended, wars have become rarer and less deadly. More British soldiers died on the first day of the Battle of the Somme than in every post-1945 conflict put together.

The Isil barbarity in the Middle East is so shocking, perhaps, because it comes against a backdrop of unprecedented world peace.

We have recently been celebrating a quarter-century since the collapse of the Berlin Wall, which kicked off a period of global calm. The Canadian academic Steven Pinker has called this era the “New Peace”, noting that conflicts of all kinds – genocide, autocracy and even terrorism – went on to decline sharply the world over. Pinker came up with the phrase four years ago, but only now can we see the full extent of its dividends.

With peace comes trade and, ergo, prosperity. Global capitalism has transferred wealth faster than foreign aid ever could.

A study in the current issue of The Lancet shows what all of this means. Global life expectancy now stands at a new high of 71.5 years, up six years since 1990. In India, life expectancy is up seven years for men, and 10 for women. It’s rising faster in the impoverished east of Africa than anywhere else on the planet. In Rwanda and Ethiopia, life expectancy has risen by 15 years.
