In A Raisin in the Sun, Lorraine Hansberry does not reject integration or the economic and moral promise of the American dream; rather, she remains loyal to this dream while looking, realistically, at its incomplete realization. Once we recognize this dual vision, we can accept the play`s ironic nuances as deliberate social commentaries by Hansberry rather than as the "unintentional" irony that Bigsby attributes to the work. Indeed, a curiously persistent refusal to credit Hansberry with a capacity for intentional irony has led some critics to interpret the play`s thematic conflicts as mere confusion, contradiction, or eclecticism. Isaacs, for example, cannot easily reconcile Hansberry`s intense concern for her race with her ideal of human reconciliation. But the play`s complex view of Black self-esteem and human solidarity as compatible is no more "contradictory" than Du Bois` famous, well-considered ideal of ethnic self-awareness coexisting with human unity, or Fanon`s emphasis on an ideal internationalism that also accommodates national identities and roles.
