I am naturally anti-slavery. If slavery is not wrong, nothing is wrong. I can not remember when I did not so think, and feel. And yet I have never understood that the Presidency conferred upon me an unrestricted right to act officially upon this judgment and feeling. It was in the oath I took that I would, to the best of my ability, preserve, protect, and defend the Constitution of the United States. I could not take the office without taking the oath. Nor was it my view that I might take an oath to get power, and break the oath in using the power. I understood, too, that in ordinary civil administration this oath even forbade me to practically indulge my primary abstract judgment on the moral question of slavery. I had publicly declared this many times, and in many ways. And I aver that, to this day, I have done no official act in mere deference to my abstract judgment and feeling on slavery. I did understand however, that my oath to preserve the constitution to the best of my ability, imposed upon me the duty of preserving, by every indispensable means, that government - that nation - of which that constitution was the organic law.
