The British philosopher John Gray is a good counterpart to Pinker's idea of progress. He focuses on the myths of progress, civilisation and freedom.
This is his response to Pinker: https://www.theguardian.com/books/2015/mar/13/john-gray-stev... "A new orthodoxy, led by Pinker, holds that war and violence in the developed world are declining. The stats are misleading, argues Gray – and the idea of moral progress is wishful thinking and plain wrong"
One example: Torture was recently brought back in the leading liberal democracy of the world. Something that was once thought to have been made illegal everywhere was made legal (waterboarding) but not in a backward dictatorship, but in the vanguard of progress and liberty - the USA. Now, Obama made it illegal again (mostly), so that shows that you have to fight to keep your progressions. Progress does not occur automatically, and once achieved, it doesn't stay, Gray argues. I think Gray also argues that wars are mostly many and small proxy wars that occur all the time instead of larger grander affairs.
I think his current ideas on Freedom area also similar. We assume that western democracies are the best ever and getting more freer, but there are examples of a decline in freedoms, in a decline in enlightenment values etc. In a previous book, Gray even highlights that the Enlightenment itself was flawed (with leading figures being overtly racist to say the least) and that we shouldn't put a halo around it by default - rather that there is nuance, and that it's a fragile thing. He also points that whilst the Enlightenment and Freedom is an old idea, ISIS and Islamic terrorism is actually a modern thing. Modern != Progress.
He encourages us to assume that progress is fragile, is not automatically improving and that we need to be active in defending our freedoms, our progress and the things we take for granted.
