Never, surely, has there been a question agitated, in which those principles were so deeply at issue, as in the one which is now before the American people. I need scarcely say, that I allude to the Missouri state bill, and to the introduction of slaves beyond the Mississippi. This subject has been ably and repeatedly discussed. A universal expression of sentiment has gone forth from the people of the northern and middle states, and it has awakened powers of eloquence and argument that have seldom been surpassed. That first burst of emotion has subsided; and now that the question is upon the point of being settled, it may not be altogether useless to recall the attention of the public to the subject. That slavery is a crime against God and nature, and that its existence in our free country is a most dangerous and lamentable evil, cannot be doubted. Our only apology as a nation for its existence, is, that we found it among us, and that an overruling necessity obliged us to leave its extirpation to the hand of time and experience. The august founders of our republic have not once named it in the constitution, as if they were unwilling that so foul a name should stain the purity of our escutcheon, as if it were a crime against humanity too execrable to be uttered. They looked forward to a period when it should cease and be forgotten, and made ample provision for its future annihilation. Their solemn declaration to the world, "We hold these truths to be self-evident, that all men are created equal; that they are endowed by their Creator with certain _unalienable_ rights, and that among these are life, _liberty_, and the pursuit of happiness," had otherwise been the worst of mockeries.
