Lincoln at Cooper Union -- Excerpts -- 2 of 3

New York, New York
February 27, 1860

But you will break up the Union rather than submit to a denial of your Constitutional rights.

That has a somewhat reckless sound; but it would be palliated, if not fully justified, were we proposing, by the mere force of numbers, to deprive you of some right, plainly written down in the Constitution. But we are proposing no such thing.
When you make these declarations, you have a specific and well-understood allusion to an assumed Constitutional right of yours, to take slaves into the federal territories, and to hold them there as property. But no such right is specifically written in the Constitution. That instrument is literally silent about any such right. We, on the contrary, deny that such a right has any existence in the Constitution, even by implication.

Your purpose, then, plainly stated, is that you will destroy the Government, unless you be allowed to construe and enforce the Constitution as you please, on all points in dispute between you and us. You will rule or ruin in all events.

This, plainly stated, is your language. Perhaps you will say the Supreme Court has decided the disputed Constitutional question in your favor. Not quite so. But waiving the lawyer's distinction between dictum and decision, the Court have decided the question for you in a sort of way. The Court have substantially said, it is your Constitutional right to take slaves into the federal territories, and to hold them there as property. When I say the decision was made in a sort of way, I mean it … was mainly based upon a mistaken statement of fact - the statement in the opinion that "the right of property in a slave is distinctly and expressly affirmed in the Constitution."

An inspection of the Constitution will show that the right of property in a slave is not "distinctly and expressly affirmed. To show all this, is easy and certain.

When this obvious mistake of the Judges shall be brought to their notice, is it not reasonable to expect that they will withdraw the mistaken statement, and reconsider the conclusion based upon it?

And then it is to be remembered that "our fathers, who framed the Government under which we live" - the men who made the Constitution - decided this same Constitutional question in our favor, long ago - decided it without division among themselves, when making the decision; without division among themselves about the meaning of it after it was made, and, so far as any evidence is left, without basing it upon any mistaken statement of facts.

Under all these circumstances, do you really feel yourselves justified to break up this Government unless such a court decision as yours is, shall be at once submitted to as a conclusive and final rule of political action? But you will not abide the election of a Republican president! In that supposed event, you say, you will destroy the Union; and then, you say, the great crime of having destroyed it will be upon us! That is cool. A highwayman holds a pistol to my ear, and mutters through his teeth, "Stand and deliver, or I shall kill you, and then you will be a murderer!"
