I may only be half sane, however it does seem that having a shared language would make other languages into something like vestigial limbs unless one of them become truly critical to at least one particular (sub)-culture.

So that could well lay the foundation for one language. Even if there are other languages that are spoken for fun then I don't see how that prevents cohesion to nearly the same degree as not having a common language does.

@Greenhavoc. How do you think that having one race would make everything else easier? How is it easier to go from many countries to one country (no countries) when there is one race as opposed to many? I don't see it.
