How does the book Common Sense affect the character Isabel in the book "Chains" by Laurie Anderson?

Common Sense is a very famous work of political theory by the American revolutionary Tom Paine. Soon after it was published, it became a hugely influential book among supporters of the Revolution and inspired many with its combination of stirring rhetoric and meticulously constructed argument in support of American independence. In Chains, the slave girl Isabel is given a copy of Common Sense by a book-seller. He tells her that the words it contains are dangerous and that she should commit them to memory.
Once Isabel has finished reading the book, she realizes just what the book-seller meant. The work is a call to arms for the American people to liberate themselves from the tyranny of King George III. One passage in particular fires her imagination. It's where Paine, railing against the principle of hereditary monarchy, states that no one has the right to set their family over all others simply by virtue of their birth. Isabel applies this sentiment to her own situation; she takes Paine's radical, emancipatory message to heart. She now has validation from the wise words of a great thinker that everyone is equal. In Paine's words, she sees the promise of equality for all, including a young African American slave such as herself.
