This, then, is the legitimate province of Jurisprudence, _Stare super antiquas vias_, to maintain the ancient landmarks, to respect authority, to guard the integrity of the law as a science, that it may be a certain rule of decision, and promote that security of life, liberty, and property, which, as we have seen, is the great end of human society and government. Thus industry will receive its best encouragement; thus enterprise will be most surely stimulated; thus constant additions to capital by savings will be promoted; thus the living will be content in the feeling that their earnings are safely invested; and the dying be consoled with the reflection that the widow and orphan are left under the care and protection of a government, which administers impartial justice according to established laws. With jurisprudence, lawyers have the most, nay all, to do. The opinion of the Bar will make itself heard and respected on the Bench. With sound views, their influence for good in this respect may well be said to be incalculable. It is indeed the noblest faculty of the profession to counsel the ignorant, defend the weak and oppressed, and to stand forth on all occasions as the bulwark of private rights against the assaults of power, even under the guise of law; but it has still other functions. It is its office to diffuse sound principles among the people, that they may intelligently exercise the controlling power placed in their hands, in the choice of their representatives in the Legislature and of Judges, in deciding, as they are often called upon to do, upon the most important changes in the Constitution, and above all in the formation of that public opinion which may be said in these times, almost without a figure, to be _ultimate sovereign_. Whether they seek them or are sought, lawyers, in point of fact, always have filled, in much the larger proportion over every other profession, the most important public posts. They will continue to do so, at least so long as the profession holds the high and well-merited place it now does in the public confidence. PROFESSIONAL ETHICS. There is, perhaps, no profession, after that of the sacred ministry, in which a high-toned morality is more imperatively necessary than that of the law. There is certainly, without any exception, no profession in which so many temptations beset the path to swerve from the line of strict integrity; in which so many delicate and difficult questions of duty are continually arising. There are pitfalls and man-traps at every step, and the mere youth, at the very outset of his career, needs often the prudence and self-denial, as well as the moral courage, which belong commonly to riper years. High moral principle is his only safe guide; the only torch to light his way amidst darkness and obstruction. It is like the spear of the guardian angel of Paradise: No falsehood can endure Touch of celestial temper, but returns Of force to its own likeness.
