“With me, sir, there is no alternative. Painfully convinced of the unutterable wrongs and woes of slavery; profoundly believing that, according to the true spirit of the Constitution and the sentiments of the fathers, it can find no place under our National Government — that it is in every respect sectional, and in no respect national — that it is always and everywhere the creature and dependent of the States, and never anywhere the creature or dependent of the Nation, and that the Nation can never, by legislative or other act, impart to it any support, under the Constitution of the United States; with these convictions, I could not allow this session to reach its close, without making or seizing an- opportunity to declare myself openly against the usurpation, injustice, and cruelty, of the late enactment by Congress for the recovery of fugitive slaves. Full well I know, sir, the difficulties of this discussion, arising from prejudices of opinion and from adverse conclusions, strong and sincere as my own. Full well I know that I am in a small minority, with few here to whom I may look for sympathy or support. Full well I know that I must utter things unwelcome to many in this body, which I cannot do without pain. Full well I know that the institution of slavery in our country, which I now proceed to consider, is as sensitive as it is powerful — possessing a power to shake the whole land with a sensitiveness that shrinks and trembles at the touch. But, while these things may properly prompt me to caution and reserve, they cannot change my duty, or my determination to perform it. For this I willingly forget myself, and all personal consequences. The favor and good-will of my fellow-citizens, of my brethren of the Senate, sir, — grateful to me as it justly is — I am ready, if required, to sacrifice. All that I am or may be, I freely offer to this cause.”
