Peter G. Ossorio

Peter G. Ossorio (4 May 1926 – 24 April 2007) was an American psychologist best known for his development of descriptive psychology, a pragmatic and theory neutral pre-empirical approach to the study of behavior. Ossorio in his 2006 volume, The Behavior of Persons, explicated the concept of "Persons" by creating a conceptual map of the interdependent concepts of "Individual Person", "Language", "Action", and "Reality".

He described persons as individuals whose history is, paradigmatically, a history of Deliberate Action in a dramaturgical pattern.
