Background Information

• G. K. Chesterton: St. Thomas Aquinas - Random quote from this online text:

  St. Thomas was a huge heavy bull of a man, fat and slow and quiet;
  very mild and magnanimous but not very sociable; shy, even apart
  from the humility of holiness; and abstracted, even apart from his
  occasional and carefully concealed experiences of trance or ecstasy.
