I find it amusing that correspondents here expect concepts in neat, one paragraph or webpage bundles.
I have been reading (George Soros' handbook),
The Open Society and Its Enemies, by epistemologist Karl Popper, for more than six months, and am ~400 pages into ~800 pages. I expect to read it and then re-read it following all of the internal and external citations, and taking two years. It took me more than two years of much more diffuse reading to read and understand, as much as I do, Popper's
Logic of Scientific Discovery that established falsification as an answer to the Problem of Demarcation.
Try it, you might like it.
