  Humbert Humbert's description of an embryo. Lolita, ch.11.

In my dreams is a country where the State is the Church and the Church the people: three in one and one in three. It is a commonwealth in which work is play and play is life: three in one and one in three. It is a temple in which the priest is the worshipper and the worshipper the worshipped: three in one and one in three. It is a godhead in which all life is human and all humanity divine: three in one and one in three. It is, in short, the dream of a madman.

-Shaw, George Bernard
  Of Heaven, Keegan speaking. John Bull's Other Island, act 4.
