Musick writes that time can be linear.

I don't dispute this point at all. To assert that something cannot have a certain attribute defies conventional rules of logic and proofs. I don't mean to defy probability by saying that time is not linear. I merely point out that we'd have a heck of a time proving anything about something we aren't sure exists in the first place.

But then again, after rereading a little Rene Descartes, I think perhaps this Internet/internet is just a boogeyman and the great master is tricking me into thinking I'm typing.
