What Is Critical Rationalism?

Critical rationalism is all encompassing, doesn't upreory rule out anything that's not science by any stretch. He doesn't even endorse conjecture knowledge, for example. So far as it's a claim about the world and the world doesn't just mean physical or anything, anything, can be assessed, critiqued, can be explained. That does stand apart. Why? Because of, as David Deutsch explains in the beginning of infinity, a culture of criticism. It's the poverty of historicism.
