General, your tank
is a powerful vehicle
it smashes down forests
and crushes a hundred men.
but it has one defect:
it needs a driver.

Bertolt Brecht (1898-1956) German poet, playwright, director, dramaturgist
“General, Your Tank Is a Powerful Vehicle,” in “From a German War Primer,” The Svendborg Poems (1939) [tr. Baxandall]
