A World of Propensities

The two lectures presented here belong belong to Popper's late work, most of which is still unpublished. The first introduces a new view of causality, based on Popper's interpretation of quantum theory yet freed of all difficulty. It is a new and encouraging view of the universe: a view that easily merges with the commonsense view that our will is free. The second lecture gives a glimpse of human knowledge as it evolves from animal knowledge.
