We make out of the quarrel with others, rhetoric, but of the quarrel with ourselves, poetry.

W.B. Yeats

Irish poet, author, and dramatist W.B. Yeats observes here that poetry is best nurtured by our own internal conflict and contemplation. While we exercise our language and communication skills by debating with others, poetry is something deeply personal, expressing the unspoken, unresolved thoughts in our minds and feelings in our hearts.
