As the Senator from South Carolina is the Don Quixote, so the Senator from Illinois [Mr. DOUGLAS] is the squire of Slavery, its very Sancho Panza, ready to do its humiliating offices. This Senator, in his labored address vindicating his labored report,--piling one mass of elaborate error upon another mass,--constrained himself, as you will remember, to unfamiliar decencies of speech. Of that address I have nothing to say at this moment, though before I sit down I shall show something of its fallacies. But I go back now to an earlier occasion, when, true to native impulses, he threw into this discussion, “for a charm of powerful trouble,” personalities most discreditable to this body. I will not stop to repel imputations which he cast upon myself; but I mention them to remind you of the “sweltered venom sleeping got,” which, with other poisoned ingredients, he cast into the caldron of this debate. Of other things I speak. Standing on this floor, the Senator issued his rescript requiring submission to the Usurped Power of Kansas; and this was accompanied by a manner--all his own--befitting the tyrannical threat. Very well. Let the Senator try. I tell him now that he cannot enforce any such submission. The Senator, with the Slave Power at his back, is strong; but he is not strong enough for this purpose. He is bold. He shrinks from nothing. Like Danton, he may cry, “_De l’audace! encore de l’audace! et toujours de l’audace!_” but even his audacity cannot compass this work. The Senator copies the British officer who with boastful swagger said that with the end of his sword he would cram the “stamps” down the throats of the American people; and he will meet a similar failure. He may convulse this country with civil feud. Like the ancient madman, he may set fire to this Temple of Constitutional Liberty, grander than Ephesian dome; but he cannot enforce obedience to that tyrannical Usurpation. The Senator dreams that he can subdue the North. He disclaims the open threat, but his conduct implies it. How little that Senator knows himself, or the strength of the cause which he persecutes! He is but mortal man; against him is immortal principle. With finite power he wrestles with the infinite, and he must fall. Against him are stronger battalions than any marshalled by mortal arm,--the inborn, ineradicable, invincible sentiments of the human heart; against him is Nature with all her subtile forces; against him is God. Let him try to subdue these. Passing from things which, though touching the very heart of the discussion, are yet preliminary, I press at once to the main question. I.
