I just finished reading Steven Pinker’s The Better Angels of Our Nature: Why Violence Has Declined. He presents his viewpoint that the rate of violence has been steadily declining for as long as we have records of it. Being a well-respected professor and researcher, he references a plethora of sources, of almost unimaginable extensiveness, to back up his every claim. From reduction of wars between nations, to civil wars, to homicides, and even to child corporal punishment, he shows that our world has indeed become more peaceful through the ages. Moreover, he brings mathematical rigor to the table and quantifies the probability of starting a war, conflict escalation, as well as duration, among other violent incidents, such as terrorist attacks. All this strengthens his claim and leaves little room for pessimists and their gloomy outlook of the future. I recommend it to anyone who thinks otherwise, and if you need more convincing, you can also check out Bill Gates’s excellent review.
