Deontology

[Matthew Hale] was no reformer: nothing better than an expounder: every thing stated by him was stated as he found it, or conceived it to be: no inquiries as to what it ought to be: in the eyes of lawyers—not to speak of the dupes—that is to say, as yet, the generality of non-lawyers—the is and the ought to be (or, as in Greek it would be so much better—the το ον and the το δεον, from which last, Ethics has received the more expressive name of Deontology), were one and indivisible.
