Carl Gustav Hempel 08Jan1905 - 09Nov1997

  • Congress of Scientific Philosophy

    From an early age Hempel was interested in mathematics, physics, and philosophy. After taking some courses on mathematics and physics he started to dive into the world of philosophy. "In 1929, Hempel took part in the first congress on scientific philosophy organized by logical positivists" (Murzi 5).
  • The Teaching Begins

    After moving to the United States Carl Hempel began teaching at the University of Chicago. His position in Chicago was as a Research Associate in Philosophy. He only taught here for about a year before moving back to Belgium for one year with a quick transition to the City College of New York for another year of teaching. Soon after, he decided to transfer again. This time to Queens College.
  • The Raven Paradox

    The Raven Paradox
    In 1945 Hempel published an article called, "A Note on the Paradoxes of Confirmation." This article was written when, "Hempel, and the logical positivists in general, thought that scientific generalizations were universal statements (general hypotheses) that were confirmed through observation" (New World Encyclopedia, 2017). Hempel believed that any hypotheses can be proven with confirmation, rather than falsification.
  • Theoretical Terms

    Several years after his publication and introduction of, The Raven Paradox, Hempel published, "The Meaning of Theoretical Terms" (Murzi, 22). In this article, "Hempel criticizes an aspect of logical positivism’s theory of science: the distinction between observational and theoretical terms and the related problem about the meaning of theoretical terms" (Murzi, 22). Schlick believed that theoretical terms are what makes a theory true because of the way they are interpreted.
