Pablo Neruda on political poetry

"Political poetry is more profoundly emotional than any other—at least as much as love poetry—and cannot be forced because it then becomes vulgar and unacceptable. It is necessary first to pass through all other poetry in order to become a political poet. The political poet must also be prepared to accept the censure which is thrown at him—betraying poetry, or betraying literature. Then, too, political poetry has to arm itself with such content and substance and intellectual and emotional richness that it is able to scorn everything else. This is rarely achieved"
