If it were done, when 't is done, then 't were well
It were done quickly.
SHAKS.: _Macbeth,_ Act i., Sc. 7.
Once to every man and nation comes the moment to decide,
In the strife of Truth with Falsehood, for the good or evil side;
Some great cause, God's new Messiah, offering each the bloom or blight,
Parts the goats upon the left hand, and the sheep upon the right;
And the choice goes by forever 'twixt that darkness and that light.
JAMES RUSSELL LOWELL: _Present Crisis._
