Granted, but that is where context comes into play. Given that, I don't think that you can say that it is true that "I am in my car", but you can say "I am currently in my car", or "I was in my car", etc. I guess I am having trouble with using the label "true" for contingent statements; but I suppose, we do it all the time, don't we ?
Maybe it is just all the years on this site talking about logic that this seems overly pedantic, but isn't it technically correct ?
