Win the Battle, Lose the War

So in mulling over the deep divisions within the political parties, and how self serving and unwilling everyone is to compromise and consider each other's opinions, a FB friend Carole had this on her page. Not sure who wrote it but it is appropro:

"The tragedy of the polarization in politics of this era is, via Paul's example of the body, the hand has judged the brain because it cannot move, and the brain has judged the hand because it cannot think. Thus the hand moves without wisdom, the brain cannot act, and the whole body loses."
