The essence of peace is to connect two opposites. Hence, do not be alarmed if you see a person whose opinion is completely opposite from yours and you think that you will never be able to make peace with him. Or, when you see two people who are completely opposite to each other, do not say it is impossible to make peace between them. On the contrary, the essence of peace is to try to make peace between two opposites.
Rabbi Nachman of Breslov, “Peace”, 10
