Of the merits of the question or the argument, it does not come within the scope of a strictly anti-slavery paper to speak, but we cannot forbear to notice the contrast in the manner and bearing of the two debaters, and the two parties among the audience. Mr. Barker uniformly bore himself as a gentleman, courteously and respectfully towards his opponent, and with the dignity becoming his position, and the solemnity and importance of the question. We regret that we cannot say the same of Dr. Berg, who at times seemed to forget the obligations of the gentleman in his zeal as a controversialist. He is an able and skillful debater, though less logical than Mr. Barker, but he wasted his time and strength too often on personalities and irrelevant matters. His personal inuendoes and epithets, his coarse witticisms, and a bearing that seemed to us more arrogant than Christian, may have suited the vulgar and the intolerant among his party, but we believe these things won him no respect from the calm and thinking portion of the audience, while we know that they grieved and offended some intelligent and candid men who thoroughly agreed with his views. It is surely time that all Christians and clergymen had learned that men whom they regard as heretics and Infidels have not forfeited their claims to the respect and courtesies of social life, by their errors of opinion, and that insolence and arrogance, contemptuous sneers and impeachment of motives and character, toward such men, are not effective means of grace for their enlightenment and conversion. Among the audience, there was a large number of men, who also lost their self-control in their dislike to Mr. Barker's views, and he was often interrupted, and sometimes checked in his argument, by hisses, groans, sneers, vulgar cries, and clamor, though through all these annoyances and repeated provocations, he maintained his wonted composure of manner and clearness of thought. On the other hand, Dr. Berg was heard with general quiet by his opponents, and greeted with clamorous applause by his friends, who seemed to constitute a large majority of the audience, and to feel that the triumph of their cause, like the capture of Jericho of old, depended upon the amount of noise made. Mr. Barker, in giving an account of the origin of the discussion, says:-- "In December, [1853] in compliance with a request from the Sunday Institute, I began a course of lectures in Philadelphia, on the origin, authority and influence of the Scriptures. The object of the lectures was to show that the Bible is of _human_ origin, that its teachings are not of divine authority, and that the doctrine that the Bible is God's word is injurious in its tendency. "When I sent the Sunday Institute a programme of my lectures, I authorised the Secretary to announce, through the papers, that I was willing to meet any clergyman, of good standing in any of the leading churches, in public discussion on the Bible question."
