Cole gives two reasons that the Constitution's principled language fails to protect all equally: race and class.

I think language fails us as a tool oftentimes for this reason.

Zamenhof's language failed in part because it imposed intellectual rules on an organism with a mind of its own.

But where languages have failed to give correlative names, there the relation is not always so easily taken notice of.

Power struggles, jealousy and frustration when language fails them are the most obvious reasons for violent behavior among this group.

Other, more profound considerations entered as well, but with them language fails utterly.

Of course, that was one way to communicate when language failed.

I have always been alert for the places where language fails us; as a child with a stammer, I had no choice.

There was a living warp drive as well, but language failed our attempts to understand how such a being functioned.

Such a language would fail to respond to all of the situations that humans use language for.
