- I don't think continua are inherently more complex, in such a way as
- to allow Occam's razor to be invoked. If you conclude that something
- is best regarded as discrete, you ought to have some reason for your
- choice of the smallest length, as well as the structure of the lattice
- (if it is a discrete model of space, say). I don't see any good
- evidence for space as being any particular sort of lattice- for
- example- and until such appears, I think we should regard continuous
- models of space as preferable, for being less arbitrary, for
- omitting these irrelevant parameters which are needed only to
- discretize the model.
