Thus far his speeches in the Senate had been in reference to economic theories and legislation antagonistic to the interests of the South, and the usurpations of executive power, which threatened directly the rights of independent States, and indirectly the liberties of the people and the political degradation of the nation; but now new issues arose from the agitation of the slavery question, and his fame chiefly rests on his persistent efforts to suppress this agitation, as logically leading to the dissolution of the Union and the destruction of the institution with which its prosperity was supposed to be identified. The early Abolitionists, as I remember them, were, as a body, of very little social or political influence. They were earnest, clear-headed, and uncompromising in denouncing slavery as a great moral evil, indeed as a sin, disgraceful to a free people, and hostile alike to morality and civilization. But in the general apathy as to an institution with which the Constitution did not meddle, and the general government could not interfere, except in districts and territories under its exclusive control, the Abolitionists were generally regarded as fanatical and mischievous. They had but few friends and supporters among the upper classes and none among politicians. The pulpit, the bar, the press, and the colleges were highly conservative, and did not like the popular agitation much better than the Southerners themselves. But the leaders of the antislavery movement persevered in their denunciations of slaveholders, and of all who sympathized with them; they held public meetings everywhere and gradually became fierce and irritating. It was the period of lyceum lectures, when all moral subjects were discussed before the people with fearlessness, and often with acrimony. Most of the popular lecturers were men of radical sympathies, and were inclined to view all evils on abstract principles as well as in their practical effects. Thus, the advocates of peace believed that war under all circumstances was wicked. The temperance reformers insisted that the use of alcoholic liquors in all cases was a sin. Learned professors in theological schools attempted to prove that the wines of Palestine were unfermented, and could not intoxicate. The radical Abolitionists, in like manner, asserted that it was wicked to hold a man in bondage under any form of government, or under any guarantee of the Constitution.
