Evolution

HUNGER that strivest in the restless arms
Of the sea-flower, that drivest rooted things
To break their moorings, that unfoldest wings
In creatures to be rapt above thy harms ;
Hunger, of whom the hungry-seeming waves
Were the first ministers, till, free to range,
Thou mad'st the Universe thy park and grange,
What is it thine insatiate heart still craves ?
Sacred disquietude, divine unrest !
Maker of all that breathes the breath of life,
No unthrift greed spurs thine unflagging zest,
No lust self-slaying hounds thee to the strife;
Thou art the Unknown God on whom we wait :
Thy path the course of our unfolded fate.
