Abstract
In the search for a quantum theory of gravity, it is commonly accepted that the universe must be either digital or analog. Here, I wish to suggest a possible third way: that spacetime may be both discrete and continuous, in the same sense that light is neither particle nor wave, but occupies a dualistic middle ground. I examine three nascent theories of quantum gravity, and posit that, in each case, a dualistic approach has the potential to resolve open questions or, at least, stimulate fresh thinking on old questions. The conventional approaches may yet be proven to work, but that should not imply that other alternatives may not deserve consideration.
