I always thought Popper's LSD was considered his best book to read on this. I haven't read it yet, but it's been on my To-Read list for a while. Popper's view essentially boils down to: "Science can't prove anything, theories can only be corroborated." So we just have a list of theories, where some are firmer than others, correct? My complaint with Popper is that true knowledge is impossible with this set of axioms. One can't know anything with certainty--and yet everyone actually lives as if they can know something. I find people that subscribe to Popper's (and Hume and Russell before him) to be hypocrites as they interact with the natural world. Operating with a set of theories that could never be 100% certain, yet acting as if they were. How sure are you that you're correct and I'm wrong? 40% or 60%?
