6. Progress in Science

In lecture six, we discuss how science changes and whether it makes progress. We examine Thomas Kuhn's paradigm shift theory, suggesting science replaces one map of reality with another without objective progress. We also consider quantum mechanics paradoxes like wave-particle duality and observer dependence, and the underdetermination of theory by evidence. Dr. Orr also addresses realism vs. anti-realism, featuring Putnam's no-miracles argument that theories must approximate truth to explain their success. We conclude by examining philosophy's essential role in understanding science.
