Free and Happy

"Do any of you say that you and your family are free and happy, and what have you to do with the wretched slaves and other people? So can I say, for I enjoy as much freedom as any of you, if I am not quite as well off as the best of you. Look into our freedom and happiness, and see of what kind they are composed!!"
