Karl Popper

Definition

Karl Popper was a 20th-century philosopher known for his contributions to the philosophy of science and political philosophy, particularly his criticism of totalitarianism and his advocacy for open societies. He is famous for the concept of falsifiability, which argues that for a theory to be considered scientific, it must be testable and able to be proven false. This perspective positions Popper in contrast to Plato's political theory, which suggests a more idealistic and prescriptive approach to governance.
