   reasoning and                                                          B occurs, and therefore C occurs.

   world through observation & experience (empiricism),               • HW--complete page in HW packet titled
   experimentation, and testing of a hypothesis
 • An inductive argument is an argument in which the                  • "Three Theories of the Solar System"
   premises (or evidence) provide reasons for supporting
   the probable truth of the conclusion, but does not
   guarantee it.
    – Example = It has snowed in Chicago every December in
       recorded history.
       Therefore, it will snow in Chicago this coming December.
 • Induction is the basis for Modern Science and the Scientific
   Method because it focuses on Empiricism (Observation) in order
   to provide a theory to explain the observable data. This theory
   will be testable with predictable results.




             Some basic definitions
• Fact: an observation that has been repeatedly
  confirmed
• Law: a descriptive generalization about how the physical
  world behaves
• Hypothesis: a testable statement that can be used to                1500-1700: The use of
  build a theory (explanation).                                       Reason, Observation, and

• Theory: a well-substantiated explanation of the
  observed data that incorporates facts, laws, and tested             laws!!
  hypotheses that has not been falsified.
• In science, you don’t get any better than a theory.
  Induction is typically used to create this theory.
