Has the human condition gotten better over time? In this book, Steven Pinker argues that it has, mainly by showing how dreadful it was in the past. People still intentionally inflict unspeakable harm upon one another, but compared to the atrocities of the past, (some of which, such as animal cruelty, genocide, torture, and rape as a spoil of war, they did not even considered atrocities at the time) we have made considerable progress. In this lengthy book, Pinker provides details, data, and analysis demonstrating his point. At times, it seemed almost too much. Despite the almost painful level of detail, I found this a thoughtful and persuading mixture of history, sociology, psychology, and philosophy. I highly recommend it as a much-needed counter for the mistaken idea that humanity has somehow digressed from an idyllic past.
