I read Steven Pinker’s new book, Enlightenment Now, and came away more optimistic about humanity. We’ve made remarkable progress in even the last few decades, not to mention the drastic difference in the human experience over the past two centuries.

The book, though, is filled with an extraordinary amount of data backing up his arguments and is slow going.

TED recently released this video of Pinker’s TED Talk on the subject. In just 18 minutes, Pinker clearly makes his case. If you don’t want to make time for the book, this talk will suffice.
