All my sons is all about man's responsibility for man. Discuss

The play introduces questions that involve an individual's obligation to society, personal responsibility, and the distinction between private and public matters. Keller can live with his actions during the war because he sees himself as answerable only to himself and his family, not to society as a whole. Miller criticizes Keller's myopic worldview, which allows him to discount his crimes because they were done "for the family." The principal contention is that Keller is wrong in his claim that there is nothing greater than the family, since there is a whole world to which Keller is connected. To cut yourself off from your relationships with society at large is to invite tragedy of a nature both public (regarding the pilots) and private (regarding the suicides).
