Viewed in this aspect, the present occasion rises above any ordinary course of lectures or series of political meetings. It is the inauguration of Freedom. From this time forward, her voice of warning and command cannot be silenced. The sensitive sympathies of property, in this commercial mart, may yet again recognize property in man; the watchful press itself may falter or fail; but the vantage-ground of free discussion now achieved cannot be lost. On this I take my stand, and, as from the Mount of Vision, behold the whole field of our great controversy spread before me. There is no point, topic, fact, matter, reason, or argument, touching the question between Slavery and Freedom, which is not now open. From these I might aptly select some one, and confine myself to its development. But I should not in this way best satisfy the seeming requirement of the occasion. According to the invitation of your Committee, I was to make an address introductory to the present course of lectures, but was prevented by ill-health. And now, at the close of the course, I am to say what I failed to say at its beginning. Not as Caucus or as Congress can I address you; nor am I moved to undertake a political harangue or constitutional argument. Out of the occasion let me speak, and, discarding any individual topic, aim to exhibit the entire field, in its divisions and subdivisions, with metes and bounds. * * * * * My subject will be THE NECESSITY, PRACTICABILITY, AND DIGNITY OF THE ANTISLAVERY ENTERPRISE, WITH GLANCES AT SPECIAL DUTIES OF THE NORTH. By this enterprise I do not mean the efforts of any restricted circle, sect, or party, but the cause of the slave, in all its forms and under all its names,--whether inspired by pulpit, press, economist, or politician,--whether in the early, persistent, and comprehensive demands of Garrison, the gentler tones of Channing, or the strictly constitutional endeavors of others now actually sharing the public councils of the country. To carry through this review, under its different heads, I shall not hesitate to meet the objections urged against it, so far at least as I am aware of them. As I speak to you seriously, I venture to ask your serious attention even to the end. Not easily can a public address reach that highest completeness which is found in mingling the useful and the agreeable; but I desire to say that it will be my effort to cultivate that highest courtesy of a speaker which is found in clearness. I.
