Your quoting an opinion, as best I can tell from the little excerpt, from a concurring opinion in Dred Scott v. Sandford - one of the most notorious cases in our nation’s history.

Actually its from United States v Ward
Federal Judge Erskine Mayo Ross, a grad VMI, confederate soldier. He was a Democrat.
