From his “Introduction to the Study of International Law.”
=_161._= IMPORTANCE OF THE STUDY.
From all that has been said it has become apparent that the study of international law is important, as an index of civilization, and not to the student of law only, but to the student of history. In our land, especially, it is important, on more than one account, that this science should do its share in enlightening educated minds. One reason for this lies in the new inducements which we, as a people, have to swerve from national rectitude. Formerly our interests threw us on the side of unrestricted commerce, which is the side towards which justice inclines, and we lived far within our borders with scarcely the power to injure or be injured, except on the ocean. Now we are running into the crimes to which strong nations are liable. Our diplomatists unblushingly moot the question of taking foreign territory by force if it cannot be purchased; our executive prevents piratical expeditions against the lands of neighboring States as feebly and slowly as if it connived at them; we pick quarrels to gain conquests; and at length, after more than half a century of public condemnation of the slave-trade, after being the first to brand it as piracy, we hear the revival of the trade advocated as a right, as a necessity. Is it not desirable that the sense of justice, which seems fading out of the national mind before views of political expediency or destiny, should be deepened and made fast by that study which frowns on national crimes?
And, again, every educated person ought to become acquainted with national law, because he is a responsible member of the body politic; because there is danger that party views will make our doctrine in this science fluctuating, unless it is upheld by large numbers of intelligent persons; and because the executive, if not controlled, will be tempted to assume the province of interpreting international law for us. As it regards the latter point it may be said, that while Congress has power to define offences against the laws of nations, and thus, if any public power, to pronounce authoritatively what the law of nations is,
