An Analysis of Steven Pinker's The Better Angels of Our Nature

Stephen Pinker's optimistic 2011 book argues that, despite humanity's biological tendency toward violence, we are, in fact, less violent today than ever before citing extensive statistical evidence.
Reasoning is the critical thinking skill concerned with the production of arguments: making them coherent, consistent, and well-supported; and responding to opposing positions where necessary. The Better Angels of Our Nature offers a step-by-step class in precisely these skills. Author Steven Pinker's central thesis is simple: mankind has become increasingly less violent over the centuries, and will continue to do so. Pinker is aware, though, that many people instinctively believe the opposite, and Better Angels is devoted to marshalling data to support and illustrate this central argument, as well as a series of secondary arguments about how and why humanity has become less violent. Pinker's interpretative skills - understanding the meaning of the complex evidence from history - are also on display throughout, as he tackles the ambiguities of his data, the problems it presents, and the viable inferences one can draw from it.
