From your same source (The Collected Works of Abraham Lincoln edited by Roy P. Basler):
"Negro equality. Fudge! How long in the Government of a God great enough to make and maintain this Universe, shall there continue knaves to vend and fools to gulp, so low a piece of demagoguism as this?" -- Abraham Lincoln I have to say, though, these "collected works" keep setting off my BS-O-Meter. The language just doesn't see authentic.
Again, I caution you against doing what so may do concerning Lincoln's words. The "Fudge" quote is a fragment from speech. Lincoln often prefaced his public words to suit the of the "mood" of the audience but he always ended on the same note --- slavery was wrong and expansion of slavery should not be permitted. Only the most radical of his day, men such as Horace Greeley, publicly advocated equality for blacks. That is why most southern states had an open reward on the head of Greeley. Most anti-slavery people were not advocating equality (at least not openly). Lincoln detractors on both the far left and the far right always use the Lincoln's openings lines without including the punch line.
I'd also remind you that seven years after the so-called "Fudge" remarks, slavery was all but ended and Lincoln called for voting rights for blacks. It was the last public speech he ever made. In the audience when he made that call was a man named John Wilks Booth who vowed then and there to kill Lincoln over the issue of "Negro" equality.
Like I said, in that day it could be very dangerous to say what you really think.
