The play is essentially a crtique of McCarthyism and the the communist scare of the 1950s. Miller saw the parallels between the witch hunts and the McCarthy trials, and found the witch trials to be a compelling vehicle for discussing modern events. Key themes include:
1. People gaining absolution from the powers-that-be by confessing the sins of others.
2. The power of community rituals, such as confession.
3. The role of political opposition and the consequences of compliance (passive or active).
4. The consequences of a polarized world views and mass hysteria.
These are just a few of the themes. The play is quite clearly a great tragedy, but remains a tragedy for our times. Through characters we can connect with, Miller convincingly shows us that the lessons from the witch hunts still apply. As a reader, I am convinced that Miller's play remains relevant and powerful in the twenty-first century. Miller has left me with questions, regarding world events in 2002 and 2003, that I did not have before reading the play.
I read this play in only a couple hours. It is compelling, engaging, and difficult to put down. Personally, I feel this text stands a great chance of making it onto my "top ten" list of best manuscripts. I highly recommend this play.
