Possible Implications of the Quantum Theory of Gravity
  We consider the implications of some simple assumptions about the nature of the quantum theory of gravity which are plausible for a class of possible theories I have been attempting to construct. The simple assumptions turn out to have surprizingly wide implications of a type one might call philosophical. The paper is short and nontechnical. ( This builds on recent unpublished work of Lee Smolin, but comes to opposite conclusions).
