The headway made around the turn of the millennium is not a fluke. It’s a continuation of a process set in motion by the Enlightenment in the late 18th century that has brought improvements in every measure of human flourishing.Comment: Reflect on the word "progress" and "progressive." "Progressive" has come to be associated with a left political movement. But let's reflect on its literal sense. Human Progress. It's not the Left-Progressives who are behind this excellent site that validates Pinker's thesis and data.
I think someone like Peter Thiel, who isn't as optimistic as Pinker, as almost like a visionary prophet for human progress, especially as viewed through a technological lens. His thesis is that we have been stagnating since the 1970s. Yet, much of Pinker's data has shown how much better the rest of the world has become since 70s. Yes, the least well off parts of the world. And they've become better off while taking advantage of the breakthroughs of the 1st world which Thiel sees as stagnating since 1970.
Information Technology of course, is excepted. (And what a big exception it is.)
Regarding the "Enlightenment" part of the thesis, it helps to look at periods on a timeline. The way I see it, Enlightenment ended around 1800, the very year in which all of this progress started to take off. It could be what triggered the growth is that's when aliens or spirits started diffusing knowledge down to humanity. But that, alas, is not a falsifiable hypothesis, with the current level of empirical understanding we have.
So I'm assuming and concluding it was the seeds planted by the Enlightenment figures like America's Founders and their influences. Men like Ben Franklin, Thomas Jefferson, Joseph Priestley, Richard Price, all of whom were either actual or armchair scientists and wanted to put man's focus on figuring out how material things work and how we can improve things.
As Franklin put it:
I have been long impressed with the same sentiments you so well express, of the growing felicity of mankind, from the improvements in philosophy, morals, politics, and even the conveniences of common living, and the invention and acquisition of new and useful utensils and instruments; so that I have sometimes almost wished it had been my destiny to be born two or three centuries hence. For invention and improvement are prolific, and beget more of their kind. The present progress is rapid. Many of great importance, now unthought of, will, before that period, be produced; and then I might not only enjoy their advantages, but have my curiosity gratified in knowing what they are to be. I see a little absurdity in what I have just written, but it is to a friend, who will wink and let it pass, while I mention one reason more for such a wish, which is, that, if the art of physic shall be improved in proportion to other arts, we may then be able to avoid diseases, and live as long as the patriarchs in Genesis; to which, I suppose, we should have little objection.It's interesting to see how Franklin mentions wanting to live 200-300 years in the future to see how all of this unfolds. He wrote the letter in 1788. Meaning Franklin wants to see 1988-2088. In other words, right now.
