quarrel

It takes two to quarrel, but only one to end it.

"Out of the quarrel with others we make rhetoric;
out of the quarrel with ourselves we make poetry."

~William Butler Yeats~

There is some truth in everything.
Views and opinions are different aspects.
 Do not quarrel with others.

Carrying a poppy
he passes through
the quarrel.

It takes in reality only one to make a quarrel. It is useless for the sheep to pass resolutions in favour of vegetarianism while the wolf remains of a different opinion.
