As policy analysts have discovered the limitations of quantitative tools and economic analysis in confronting complex social and political issues, members of the profession have turned increasingly to the ideas and perspectives of the humanities. For the analyst who faces ethical questions, whether they involve personal conduct or broad social judgment, insights from history, philosophy, literature, and political theory may offer breadth and understanding. Attention to the humanities-whose concerns are the uncertain realms of thought and character and action-may be especially valuable in sensitizing students of policy analysis to the difficulties they will confront.
