Karl Popper (philosopher)

Karl Popper was a philosopher known for his work on the philosophy of science. He argued that scientific theories can never be proven true definitively but can only be tested and potentially falsified. He emphasized that for a theory to be scientific, it must be testable and open to criticism. Popper also promoted the idea of "critical rationalism," encouraging continuous questioning and testing of ideas, which advances knowledge. His approach helped distinguish scientific efforts from non-scientific claims, fostering an open, critical mindset essential for progress.
