Unitarian Minister Theodore Parker, a prominent abolitionist, delivers his “The Function And Place Of Conscience, In Relation To The Laws Of Men” sermon to his congregation, at the Melodeon, in Boston Massachusetts:
I may take the juror’s oath to give a verdict according to the law and the testimony. The law is plain, let us suppose and the testimony conclusive. … If I have extinguished my manhood by my juror’s oath, then I shall do my official business and find Greatheart [a hypothetical self-emancipated slave] guilty, and I shall seem to be a true man; but if I value my manhood, I shall answer after my natural duty to love a man and not hate him, to do him justice, not injustice, to allow him the natural rights he has not alienated, and shall say, “Not guilty.”
