Hymn to Intellectual Beauty (excerpt)

Spirit of BEAUTY, that dost consecrate
With thine own hues all thou dost shine upon
Of human thought or form, where art thou gone?
Why dost thou pass away and leave our state,
This dim vast vale of tears, vacant and desolate?
Ask why the sunlight not for ever
Weaves rainbows o'er yon mountain-river,
Why aught should fail and fade that once is shown,
Why fear and dream and death and birth
Cast on the daylight of this earth
Such gloom, why man has such a scope
For love and hate, despondency and hope?

Percy Bysshe Shelley.
