Carl Gustav Hempel (January 8, 1905-November 9, 1997)

  • Migration

    Hempel migrated to the United States, escaping Nazi Germany before the start of World War II. Moving to New York City in 1939, teaching at Queens College where he published several of his work like “A Purely Syntactical Definition of Confirmation,” and “The Journal of Symbolic Logic,” (Wolters 109).
  • "Studies in the Logic of Explanation"

    He published “Studies in the Logic of Explanation,” explaining that the fact of a scientific explanation there must be have a fact and premises. Deriving that a theory is true in Nature, but has certain limitations. And a scientific law is realistic in nature and are not used for predictions. The original Kepler’s Law only works with certain limitations in space (theory) while Newton’s law applied to every celestial body (Hempel 54).
  • "The Meaning of Theoretical Terms"

    Published “The Meaning of Theoretical Terms,” this article was a form of criticism against theoretical terms. Two key points he made was that observational concept do not exist but are given by other theoretical terms that derived from other theories. Second, all scientific statements like scientific theories are falsifiable (Hempel 5).
  • "Provisoes: A Problem concerning the Inferential Function of Scientific Theories”

    Published “Provisoes: A Problem concerning the Inferential Function of Scientific Theories,” criticizing the deductive nature of theories. Meaning that it is not obtainable from certain theories such as the positions of the planets it not derived from Newton’s Law of Gravity, but by assumptions (Hempel 28).
