    * to build science
    * to guide as a frame (what to look, how to think, and how to look at)
    * to explain phenomena
    * to predict phenomena (to provide a context for predictions)
    * Empirically relevant (testing) and always tentative (deductive cycle)
      * via research (hypothesis testing)
      * hence, not fixed
    * generalized statement regarding a connection between A and B (idea, concept, construct, phenomena, etc)
    * Levels ?
      * Micro . . . frustration and aggression
