John Keats - "Why did I laugh to-night? No voice will tell" lyrics

Why did I laugh tonight? No voice will tell. No God, no Demon of severe response, Deigns to reply from Heaven or from Hell. Then to my human heart I turn at once. Heart! Thou and I are here sad and alone; I say, why did I laugh! 0 mortal pain! O Darkness! Darkness! ever must I moan, To question Heaven and Hell and Heart in vain. Why did I laugh? I know this Being's lease, My fancy to its utmost blisses spreads; Yet would I on this very midnight cease, And the world's gaudy ensigns see in shreds; Verse, Fame, and Beauty are intense indeed, But d**h intenser--d**h is Life's high meed.
