'The Crucible' by Arthur Miller is a play set during the Salem witch trials of 1692, but it also draws parallels to the McCarthy era of the 1950s in the United States. During this time, fear of communism led to widespread suspicion, accusations, and a breakdown of community trust. Miller's play dramatizes the dangers of mass hysteria, where individuals are accused of wrongdoing based on little evidence, resulting in chaos and injustice. The story involves characters caught in a web of fear, false accusations, and moral panic. A key phrase from the play, 'envy is a deadly sin,' highlights the motives behind many accusations, revealing how personal grudges fueled the hysteria. The play exemplifies how fear can distort reality and lead to irrational decisions, mirroring the real events of McCarthyism.
