ULTIMATUM by Philip Larkin

But we must build our walls, for what we are
Necessitates it, and we must construct
The ship to navigate behind them, there.
Hopeless to ignore, helpless instruct
For any term of time beyond the years
That warn us of the need for emigration:
Exploded the ancient saying: Life is yours.
For on our island is no railway station,
There are no tickets for the Vale of Peace,
No docks where trading ships and seagulls pass.
Remember stories you read when a boy
– The shipwrecked sailor gaining safety by
His knife, treetrunk, and lianas – for now
You must escape, or perish saying no.
