The memory of Henry Sidgwick is not yet in need of revival. It lives a natural life among us, and will live so long as those who saw and heard him draw breath. Still the generations, as generations must be reckoned in this place, succeed each other rapidly, and already I may be informing, rather than reminding, some of you when I say that among his many generous acts was the endowment of a readership in English Law, of which one of his pupils was fortunate enough to be the first holder. If that pupil ventures to speak here this afternoon, it will not be unnatural that he should choose his theme from the borderland where ethical speculation marches with jurisprudence.

Ethics and Jurisprudence That such a borderland exists all would allow, and, as usually happens in such cases, each of the neighbouring powers is wont to assert, in practice, if not in theory, its right to define the scientific frontier. We, being English, are, so I fancy, best acquainted with the claims of ethical speculation, and in some sort prejudiced in their favour. We are proud of a long line of moralists, which has not ended in Sidgwick and Martineau and Green, in Herbert Spencer and Leslie Stephen, and we conceive that the ‘jurist’, if indeed such an animal exists, plays, and of right ought to play, a subordinate, if not subservient, part in the delimitation of whatever moral sciences there may happen to be.
