  1. On Theory Construction and Verification An Article by Robert R. Sterling Summarized by AdriaBakke

  2. DISTINGUISHED AREAS OF LANGUAGE Syntactics Semantics Pragmatics

  3. SYNTACTICS • "If all electrons have magnetic moments and particle x has no magnetic moment, then particle x is not an electron“ • "If all bzrs have wales and x has no wale, then x is not a bzr."

  4. SEMANTICS • Analytic propositions are proved by the use of syntactical rules. They are either true (valid) or contradictory. • Empirical propositions are verified by operations of observation. They are either true (conform with the observations) or false.

  5. PRAGMATICS • People may interpret signs in ways other than intended.

  6. SCIENCE CLASSIFICATIONS Nonempirical Empirical

  7. NONEMPIRICAL • Composed of only analytic propositions. • Truth is determined through previously established meanings of signs and definitions of words.

  8. EMPIRICAL • Composed of empirical and analytical propositions. • Truth can be determined by either observation or previously established meanings of signs or definitions of words. • Testing the analytical propositions separate from the empirical is known as axiomatization or formalization.

  9. EMPIRICAL CONTINUED • For a theory to be empirical, the output has to be verified. • Theoretical terms • Observational terms

  10. PARTS OF EMPIRICAL SCIENCE Formal System Interpretation

  11. TYPES OF OBSERVATIONS Input Output
