Soft words win hard hearts. You scratch my back, I'll scratch yours. Come now and let us reason together. When two quarrel, the person who keeps silent first is the most praiseworthy. Might overcomes right.
Smooth words make smooth ways.
Better half a loaf than no bread at all. Truth lies in knowledge, not in majority opinion. He who fights and runs away lives to fight another day. He hath conquered well that hath made his enemies flee. Kill your enemies with kindness.
