It is a question of building which is at the root of the social unrest of today: architecture or revolution.

-Le Corbusier pseudonym of  Charles EŁ  douard Jeanneret
  Vers une architecture (translated as Towards a New Architecture,1927).

   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.
