No Government can be long secure without a formidable Opposition.

-Disraeli, Benjamin, 1st Earl of Beaconsfield
  Coningsby, bk.2, ch.1.

   He has out-soared the shadow of our night; Envyand calumnyand hate and pain, And that unrest which men miscall delight, Can touch him not and torture not again; From the contagion of the world's slow stain He is secure, and now can never mourn A heart grown cold, a head grown grey in vain.

-Shelley, Percy Bysshe
Adonais, stanza 40.
