Why do postmodern philosophers use language as the basis of all knowledge, meaning etc.?

In my HS worldview class, we are reading Grentz's *Primer on Post Modernism*,  he goes through some of the main postmodern philosophers, Foucalt, Derrida, Rorty to name a few.  One common thread that seems to be running through these is a tendency to in some way connect language to meaning.  

My question is, what makes language a better understanding of "truth" or "meaning" or "knowledge," than anything else?

Postmodern philosophers argue that our entire understanding of the world is representational/symbolic/semiotic. That is when we see/hear/taste/whatever something, we mentally re-present that stimulus to our self and our understanding of that re-presentation occurs within the context of all of our historical, cultural, and personal re-presentations. Much of postmodern philosophy focus on the linguistic, because it's a common and powerful form of representation, but most (if not all) also recognize that wide rage of non-linguistic representations that we also use in our minds when understanding.  

PoMo philosophers don't argue that language is a better understanding of truth, meaning, or knowledge, they argue that it is the only understanding. For postmodern philosophers, there is no such thing as non-linguistic/non-symbolic knowledge or meaning. All knowlege or meaning is a re-presentation.
