Popper introduces the concept of "falsifiability" in experimentation. The preface provides a short, open introduction to Popper's thoughts of validity and arguing of the usefulness of philosophy. The work itself shows the relation between the continuous quest for knowledge of philosophers and scientists, and how neither has an absolute "truth". Popper, Karl R.

Popper starts this translation with clarification and expansion of the original preface. In this preface, he explains his original thoughts in 1934 as well as an updated view to modern (1959) views. He also proceeds to update the appendices at the end of the book to more modern expressions. The contents of the body of the book remain, for the most part, the same.

Popper proposed a falsification based approach. He proposed that science focus on proving theories false instead of true. One of the most prominent points he made, was that nothing is true. There are only theories that have yet to be proven wrong due to limits of technology or creativity, and theories that have already been falsified within the limits of the known.

In this lecture, delivered at the University of Michigan, Popper introduces three worlds of knowledge: World 1: Physical, Objective World; World 2: Psychological, Cognitive Subjective World; and World 3: Human Concepts, Abstractions, Creations in the Objective World. These three worlds of knowledge are explained in depth within the lecture as well as how they intertwine with each other.
