  • Founding the Berlin Circle

    Reichenbach helped evolve Logical Empiricism, also known as Logical Positivism by co-founding the Berlin Circle. This group, along with others such as the Vienna Circle included many famous scientists and philosophers. One of their key concepts was emotive theory which argues that a sentence is only valid if it can be empirically verified.

  • The Rise of Hitler

    As Nazism gained power, Reichenbach was fired from university position because he had Jewish ancestry. He emigrated to Turkey, where he continued to teach, and continued writing under the guidance of logical empiricism, decrying the usage of morals, ethics, and feelings in philosophy and science (Mauro)
