Principles Of Human Knowledge - pg. 52

The physical world is a genuinely linguistic system, whose elements are variously combined and concetenated in much the sort of way that letters and words are, so that they should be capable of carrying detailed messages. Just as a limited number of letters can be used to create an infinite variety of messages, so a limited number of physical elements can be combined for the same purpose. The whole is thus an informational system, in which God, of his goodness, speaks to us about what we can expect in the future. And scientists can be conceived as the grammarians of this system,. who understand how the individual elements combine to generate this or that meaning in the particular case, and are thus able to know better what is being said (see the first-edition version Principles $108).
