Rabbi Nachman of Breslav
The essence of peace is to merge two opposites. Therefore your notions should not scare you if you see another, who absolutely opposes you, and you presume that there is no chance for peace between you two. On the same token when you see two individuals who are exactly two opposites, never say it would be impossible for them to reconcile. On the contrary, and this is the perfection of peace to make it between two opposites.
