From his speech at the Cooper Union.
It is applicable to todays great arguments.

If our sense of duty forbids this, then let us stand by our duty, fearlessly and effectively. Let us be diverted by none of those sophistical contrivances wherewith we are so industriously plied and belabored - contrivances such as groping for some middle ground between the right and the wrong,........

Neither let us be slandered from our duty by false accusations against us, nor frightened from it by menaces of destruction to the Government nor of dungeons to ourselves.



LET US HAVE FAITH THAT
RIGHT MAKES MIGHT,
AND IN THAT FAITH, LET US, TO THE END,
DARE TO DO OUR DUTY AS WE UNDERSTAND IT.

Abraham Lincoln.
