James Mill was an early 19th century political philosopher who wrote at length about politics and law. From the intro: "THE object and end of the science which is distinguished by the name of Jurisprudence, is the protection of rights. The business of the present discourse is, therefore, to ascertain the means which are best calculated for the attainment of that end. What we desire to accomplish is, The protection of rights: What we have to inquire is, The means by which protection may be afforded. That rights have hitherto been very ill protected, even in the most enlightened countries, is matter of universal acknowledgment and complaint. That men are susceptible of happiness, only in proportion as rights are protected, is a proposition, which, taken generally, it is unnecessary to prove. The importance of the inquiry, therefore, is evident. It is requisite, as a preliminary, to fix, with some precision, what we denote by the expression rights. There is much confusion in the use of this term. That disorderly mass, the Roman law, changes the meaning of the word in stating its division of the subject, Jura Personarum, and Jura Rerum. In the first of these phrases, the word Jura means a title to enjoy; in the second, it must of necessity mean something else, because things cannot enjoy. Lawyers, whose nature it is to trudge, one after another, in the track which has been made for them, and to whose eyes, that which is, and that which ought to be, have seldom any mark of distinction, have translated the jargon into English, as well as into other modern languages."
