The collected Poems of Wilfred Owen, Chatto & Windus, Londen, 1964. Citaat brief Owen (pag. 19), onderstreept door Escher met uitroepteken: "While it is true that the guns will effect a little useful weeding, I am furious with chagrin to think that the Minds, which were to have excelled the civilization of two thousand years, are being annihilated - and bodies, the product of aeons of Natural Selection, melted down to pay for political statues."
