Democracy Book

Excellent material - popper's theories are clear and concise with a force behind them that most philosophers lack. Book is a collection of his lectures on his theory of 3 worlds and the mind-body problem (along with some additions to evolutionary theory) - q&a section is added to the end of each chapter or lecture, which can be a bit disjointed. Would recommend reading lecture portion straight through and returning to discussion sections later. Some questions have interesting answers and are worth reading.
