I wrote out a long post about Coleridge. Instead of repeating it, as it is gone into the depths of data limbo, I will put a poem that, taken with some of his greats, is fascinating. Also, it is candy for the Platonically inclined.

The Destiny of Nations
A VISION

Auspicious Reverence! Hush all meaner song,
Ere we have the deep precluding strain have poured
To the Great Father, only Rightful King,
Eternal Father! King Omnipotent!
To the Will Absolute, the One, the Good!
The I AM, the Word, the Life, the Living God!

Such symphony requires best instrument.
Sezie, then, my soul! from Freedom's trophied dome
The harp which hangeth high between the shields
of Brutus and Leonidas! With that
Strong music, that soliciting spell, force back
Man's free and stirring spirit that lies entranced.

For what is freedom, but the unfettered use
Of all the powers which God for us had given?
But chiefly this, him first, him last to view
Through meaner powers and secondary things
For all that meets the bodily sense I deem
Symbolically, one mighty alphabet
For infant minds; and we in this low world
Placed our backs to bright reality,
That we may learn with young unwounded ken
The substance from its shadow. Infinite Love,
Whose latence is the plenitude of all,
Thou with retracted beams, and self-eclipse
Veiling, revealest thine eternal Sun.

(it's a lot longer than this, but you can read the rest for yourself if you would like.)

Go read Kubla Khan again, and as you enter the pleasure dome, feel the cold grip of icy caves on the tender extremities of your soul!
