I know that’s a popular saying, and there is some truth to it, but it’s not the whole story. Encryption protocols used by the intelligence services, for example, are highly secure and not open source, while open source encryption protocols have themselves become vulnerable to attack.
Enigma is a primary example of this. While at the time it was considered unbreakable (by both German and Allied intelligence), the knowledge of the physical and logical operation of the Enigma device was key in breaking the code. Codebreaking usually relies on a combination of intelligence gathering and mathematical analysis, and open sourcing it solves a big part of that picture.
I’m saying this as an old school cypherpunk - I’ve since gotten out of it in favor of math I find more interesting - and a user and advocate for technologies like PGP. I used PGP for a long time on many of my emails, and I even had the PGP in Four (later, Three) Lines of Perl as my email sig to show how stupid it was to declare encryption a weapon for export purposes. What I’m saying is that I’m an ally.
I’ve also gone long past the point in my career where I feel comfortable with categoricals like that, and I had a few minutes to type up a reply that will be read by fewer than ten people.
This made me hesitate, but then I decided that you’re more than capable of reading a summary or skimming a book and deciding whether or not it makes a fit.
Let me start with some obvious ones:
Orientalism by Edward Said
A People's History of the United States by Howard Zinn
90% of Chomsky’s work
21 Things They Don’t Teach You About Capitalism by Ha-Joon Chang. Chang is an economist who I believe studied under the Nobel laureate Joseph Stiglitz. They both research the economies of developing countries, with Chang having a specialization in South Korea. He accused developed countries of “kicking away the ladder” when they force the Washington Consensus on developing economies while having violated those norms as their own economies developed.
Guns, Germs, and Steel by Jared Diamond - There’s a lot wrong with the book but it does make for an effective deconstruction of the myth of western cultural superiority by proposing a physical/geographical explanation.
Better than GGS would be any book by David Graeber, who for my money was the greatest anthropologist of our time and who brings a radical preconception of some of the most treasured but false narratives in the development of western history and capitalism. Debt is his most famous work, I think, but I’d especially recommend The Dawn of Everything.
Che Guevara by Jon Lee Anderson - the best bio of Che that I’ve read, but it’s really, really long. Maybe just watch Motorcycle Diaries and Even The Rain (which is about modern and even liberal colonialism but not Che).
Anything about James Baldwin
The Social Conquest of the Earth by EO Wilson. Wilson was the biologist who founded the field of sociobiology and who towards the end of his career came to the conclusion that its because humans exhibit the highest levels of cooperation (eusociality) that we’ve come to dominate the planet, for better and for worse.
I realize that a lot of these are US centric, and I’ve left out virtually everything on LGBT history and culture, but I think this might be a good start.
