You cannot break the human spirit through political coercion. The human spirit is inspired by culture, which is a product of centuries of intellectual and materialistic endeavors. It might bend when political coercion is applied but when political coercion is removed, the human spirit will, like a spring, revert back to its original shape. However, the human spirit can be broken by attacking and transforming culture. That is why the philosophies and political movements, which aim to create a different kind of human being, focus on culture.
