Do agree with Gould's statement that "Facts are the world's data. Theories are structures of ideas that explain and interpret facts."? I think that implies that they are related, in that theories explain and interpret facts. If a theory could be a fact then could I also make the statement(In Gould's Definition here) that Theories are structures of ides that explain and interpret theories? If theory and fact are not mutually exclusive then that meaningless statement would be acceptable.
