An excerpt from the poem by Rudyard Kipling, originally published 1919.
As it will be in the future, it was at the birth of Man —
There are only four things certain since Social Progress began —
That the Dog returns to his Vomit and the Sow returns to her Mire,
And the burnt Fool’s bandaged finger goes wabbling back to the Fire —
And that after this is accomplished, and the brave new world begins
When all men are paid for existing and no man must pay for his sins
As surely as Water will wet us, as surely as Fire will burn
The Gods of the Copybook Headings with terror and slaughter return!
