Then the revulsion came that always comes
After these dizzy elations of the mind:
And with a passionate pang of doubt I cried,
'O mountain-born, sweet with snow-filtered air 710
From uncontaminate wells of ether drawn
And never-broken secrecies of sky,
Freedom, with anguish won, misprized till lost,
They keep thee not who from thy sacred eyes
Catch the consuming lust of sensual good
And the brute's license of           will.
