“The speech of Senator Sumner at the Cooper Institute will produce a startling effect in Europe. It may safely be asserted that the opinions of that gentleman upon international politics are received with greater favor in England and France than those of perhaps any other American statesman. He is regarded as most liberal and cosmopolitan in his views; his acquaintance with leading public men in both countries is known to be alike extended and intimate; and such declarations, therefore, as those to which he gave utterance last Thursday evening will necessarily have extraordinary weight in political and commercial circles.” The _Transcript_, of Boston, said:-- “The great speech of Senator Sumner upon the Foreign Relations of the United States will command the attention of all intelligent men in Europe and America. It is a thorough and exhaustive discussion of English and French diplomacy, so far as either bears upon the present war. The effect of the complete exposition of the policy of Great Britain with regard to Slavery since 1807, proving, by clear and irrefragable historical instances, the apostasy of the existing ministry to the high principles so long maintained, must be great among all reflective Englishmen.… Mr. Sumner’s comprehensive views of International Law, the extensive learning with which he enriches the discussion of it, his convincing logic and kindling eloquence, together with the results he reaches, make this address one of great importance, and cannot but exert the most beneficial influence in this country and in Europe.” The _Independent_, of New York, in a leading article entitled “Sumner and Burke,” presented an elaborate parallel between the recent speech and that against Warren Hastings.
