Let me ask you to remember in your public course the rules of Right which you obey in private life. The principles of morals are the same for nations as for individuals. Pardon me, if I suggest that you have not acted invariably according to this truth. You would not in your private capacity set your name to a falsehood; but you have done so as Representative in Congress. You would not in your private capacity countenance wrong, even in friend or child; but as Representative you have pledged yourself "not to withhold your vote from any reasonable supplies which may be called for"[199] in the prosecution of a wicked war. Do by your country as by friend or child. To neither of these would you furnish means of offence against a neighbor; do not furnish to your country any such means. Again, you would not hold slaves. I doubt not you would join with Mr. Palfrey in emancipating any who should become yours by inheritance or otherwise. But I do not hear of your effort or sympathy with those who seek to carry into our institutions that practical conscience which declares it to be as wrong in States as in individuals to sanction slavery. [199] Speech on the Tariff, June 25, 1846: Congressional Globe, Twenty-ninth Congress, First Session, p. 970. Let me ask you still further--and you will know if there is reason for this request--to bear testimony against the Mexican War, and all supplies for its prosecution, regardless of the minority in which you are placed. Think, Sir, of the cause, and not of your associates. Forget for a while the tactics of party, and all its subtle combinations. Emancipate yourself from its close-woven web, spun as from a spider's belly, and move in the pathway of Right. Remember that you represent the conscience of Boston, the churches of the Puritans, the city of Channing. Meanwhile a fresh election is at hand, and you are again a candidate for the suffrages of your fellow-citizens. I shall not anticipate their verdict. Your blameless private life and well-known attainments will receive the approbation of all; but more than one of your neighbors will be obliged to say,-- "Cassio, I love thee, But nevermore be officer of mine!" I am, Sir, your obedient servant, CHARLES SUMNER. OCTOBER 26, 1846. REFUSAL TO BE A CANDIDATE FOR CONGRESS. NOTICE IN THE BOSTON PAPERS, OCTOBER 31, 1846.
