  1. It [the earth] was in the centre of the Kosmos; it remained stationary because of its equal distance from all parts of the outer revolving spheres; there was no cause determining it to move upward rather than downward or sideways, therefore it remained still. Its exhalations nourished the fire in the peripheral regions of the Kosmos.
  2. 1874-1875, William Ewart Gladstone, The Church of England and Ritualism […] the spirit of Beauty was so profusely poured forth, that it seemed to fill the life and action of man as it fills the kingdoms of nature; the one, like the other, was in its way a Kosmos.
