“Art transcends war. Art is the language of God and war is the barking of men. Beethoven is bigger than war.”

Introduction
The Wedge (1944)
Context: There is no poetry of distinction without formal invention, for it is in the intimate form that works of art achieve their exact meaning, in which they most resemble the machine, to give language its highest dignity, its illumination in the environment to which it is native. Such war, as the arts live and breathe by, is continuous.
It may be that my interests as expressed here are pre-art. If so I look for a development along these lines and will be satisfied with nothing else.

"Freedom for Whom", as translated in Brecht on Brecht : An Improvisation (1967) by George Tabori, p. 18
Context: Firebugs dragging their gasoline bottles
Are approaching the Academy of Arts, with a grin.
And so, instead of embracing them, Let us demand the freedom of the elbow
To knock the bottles out of their filthy hands.
Even the most blockheaded bureaucrat,
Provided he loves peace,
Is a greater lover of the arts
Than any so-called art-lover
Who loves the arts of war.
