St. Thomas does not use the word collocatio. His repeated phrase is distinctio rerum, which I have rendered 'distinct arrangement and collocation,' first, because such is really the meaning, and, secondly, because this argument has attracted attention, and been acknowledged to have weight, in respect of what is called the 'primitive collocation' of the materials of the universe, a collocation impossible to explain by any physical causation, and pointing evidently to some ordering and disposing Intelligence.
