The society, which meets in a hidden cave, is a place where the students can express themselves freely and engage in poetry, music, and other forms of self-expression. They believe that these activities help them to live life to the fullest, and that their school's strict curriculum is stifling their creativity and passion.
The name "Dead Poets Society" is a metaphor for the deadening effect of conformity and tradition on the students' lives. The society represents a rebellion against these forces, and the members strive to "seize the day" and live life to the fullest.
