Last in the brief enumeration of the benefits of the popular lecture, it has been the devoted, consistent, never tiring champion of universal liberty. If the popular lecturer has not been a power in this nation for the overthrow of American Slavery,--for its overthrow in the conscientious convictions and the legal and conventional fastnesses of the nation,--then have the friends of oppression grossly lied; for none have received their malicious and angry objurgations more unsparingly than our plain-speaking gentleman who makes his yearly circuit among the lyceums. No champion of slavery, no advocate of privilege, no apologist for systematized and legalized wrong has ever been able to establish himself as a popular lecturer. The people may listen respectfully to such a man once; but, having heard him, they drop him forever. In truth, a man cannot be a popular lecturer who does not plant himself upon the eternal principles of justice. He must be a democrat, a believer in and an advocate of the equal rights of men. A slavery-loving, slavery-upholding lecturer would be just as much of an anomaly as a slavery-loving and slavery-singing poet. The taint so vitiates the whole æsthetic nature, so poisons the moral sense, so palsies the finer powers, so destroys all true sympathy with universal humanity, that the composition of an acceptable lecture becomes impossible to the man who bears it. The popular lecture, as it has been described in this article, has never existed at the South, and could not be tolerated there. Until within three years it has never found opportunity for utterance in the capital of the nation; but where liberty goes, it makes its way, and helps to break the way for liberty everywhere.
