I am highly appreciative of the very great honor which you have now conferred upon me. It is all the more grateful to me that in the ceremony which makes me an associate of this distinguished body, so prominent a part should be taken by a gentleman who, as the representative of Mexico in the capital of the United States, has not only taught me to admire his rare intellectual ability, but has won from me, by the grace and purity of his character, the warmth of friendship which adds especial pleasure to every new association with him into which I can enter. I feel, sir, that the compliment which you have paid to this little work of mine, produced without any idea that it should receive so distinguished an honor or find its way so far from home, I must ascribe rather to friendship than to any intrinsic merit of the work; but I thank you, and I am most appreciative of the honor that you do me in causing it to be translated into Spanish and making it the subject of your resolution. Circumstances have not permitted, and do not permit, that I should present to the Academy any thesis or discussion adequate to be associated with the admirable and well-considered papers which have been read by Mr. Casasus and yourself. I wish, however, in addition to expressing my thanks, to indicate in a few words the special significance which this academy and my new association with it seem to me to have. We are passing, undoubtedly, into a new era of international communication. We have turned our backs upon the old days of armed invasion, and the people of every civilized country are constantly engaged in the peaceable invasion of every other civilized country. The sciences, the literature, the customs, the lessons of experience, the skill, the spirit of every country, exercise an influence upon every other. In this peaceful interchange of the products of the intellect, in this constant passing to and fro of the people of different countries of the civilized world, we find in each land a system of law peculiar to the country itself, and answering to what I believe to be a just description of all laws which regulate the relations of individuals to each other, in being a formulation of the custom of the civil community. These systems of law differ from each other as the conditions, the customs of each people differ from those of every other people. But there has arisen in recent years quite a new and distinct influence, producing legal enactment and furnishing occasion for legal development. That is the entrance into the minds of men of the comparatively new idea of individual freedom and individual equality. The idea that all men are born equal, that every man is entitled to his life, his liberty, and the pursuit of happiness; the great declarations of principle designed to give effect to the fundamental ideas of liberty and equality, are not the outcome of the conditions or customs of any particular people, but they are common to all mankind.
