There is a natural and divine law anterior and superior to all human and civil law, by which every people has a right to live of the fruits of the soil on which they are born and in which they are buried.
— CARDINAL MANNING, Letter to Earl Grey (1868), Miscellanies, Vol. I., p. 239.
All men are originally and before any juridicial act of the will in rightful possession of the soil; that is, they have a right to be wherever nature or chance has placed them.
— EMANUEL KANT, Philosophy of Law, Part I., Chap. 2, Sec. 13.
