"Frank believed poetry to be the finest distillation of the language weather written in open or closed form"
and again further on in the forward:
"Frank believed poetry was the apex of human language..."
In a letter to a friend (sometime after writing Dune) Herbert described his style of writing. One line demonstrates his love and need for poetry when writing:
"Much of the prose in Dune started out as Haiku and then was given minimal additional word padding to make it conform to normal English structure."
---The Road To Dune (2005) by B. Herbert & K. J. Anderson
In Book I of Dune there is a great poem recited by Jessica:
'I remember salt smoke from a beach fire
And shadows under the pines -
Solid, clean...fixed -
Seagulls perched at the tip of land.
White upon green...
And a wind comes through the pines
To sway the shadows;
The seagulls spread their wings,
And fill the sky with screeches.
And I hear the wind
Blowing across our beach,
And the surf,
And I see our fire
Has scorched the seaweed'
