"It is totally unnecessary for the gentleman to remind me of my coming from a slaveholding state. I know whence I came, and I know my duty, and I am ready to submit to any responsibility which belongs to me as a senator from a slaveholding state. I have heard something said on this and a former occasion about allegiance to the South. I know no South, no North, no East, no West, to which I owe any allegiance. I owe allegiance to two sovereignty, and only two: one is the sovereignty of this Union, and the other is the sovereignty of the state of Kentucky. My allegiance is to this Union and to my state; but if gentlemen suppose they can exact from me an acknowledgement of allegiance to any ideal or future contemplated confederacy of the South, I here declare that I owe no allegiance to it; nor will I, for one, come under any such allegiance if I can avoid it."

“Impart additional strength to our happy Union. Diversified as are the interests of its various parts, how admirably do they harmonize and blend together! We have only to make a proper use of the bounties spread before us, to render us prosperous and powerful.”

“An oppressed people are authorized, whenever they can, to rise and break their fetters.”

“Precedents deliberately established by wise men are entitled to great weight. They are evidence of truth, but only evidence...But a solitary precedent...which has never been reexamined, cannot be conclusive.”
