I tried feeding the DOIs to Sci-Hub but unfortunately they don't have these documents yet. If anyone here has access may I suggest submitting them to Sci-Hub or Library Genesis? It is, after all, a bit odd to see papers like "Prior Analytics (~350 BCE)" and "The True Method (1677)" hidden behind a paywall.
I believe if you search the title ("Ideas That Created the Future") of the book, you can find it on library genesis. If anyone asks, you didn't hear it from me.
