Without it coming first and foremost, the rest doesn't come at all - I believe is the point.
Yes, I understand, but it's a flawed method of causal reasoning. Just because something comes first doesn't mean it's better, or more important, etc. It doesn't even mean it's
necessary, in fact. Dak suggested that without life there's no language--but I pointed out that computers use language, and they're not alive according to most definitions.
Just because things happened the way they did doesn't mean they had to happen that way, or that another combination of contingent events couldn't give rise to similar circumstances. This is a familiar critique of causal reasoning in philosophy going back to Hume. The privileging of origins, or of more original states, awards a higher value to earlier moments in time simply because they came first. There's no necessity there. It might be the case that our evolutionary past gave rise to the bodies/minds we now enjoy, but that doesn't mean it's impossible that similar (or the same) forms would have arisen from drastically different evolutionary conditions. On a related note, the exact same evolutionary conditions of one million years ago wouldn't necessarily give rise to the same socio-linguistic circumstances we experience today, if we were able to replay the tape (so to speak).
But aside from that, this whole argument about whether language is as important (or necessary...?) as concrete, or other material objects (a finicky definition, as language is material, whether spoken or written) is a red herring, and I always feel a bit silly when I engage in the debate. Even if life can go on existing without language, making the leap to life being more important than language is simply a non sequitur. Bear in mind, I'm not even trying to say that language is more important than life, or concrete, or anything else. In fact, my argument is that it's preposterous to make such arguments since you need language in order to conceptualize things like "life," "language," and "concrete." It makes no sense to think of importance outside of linguistic (or at the very least, higher-level representational) cognition. So from there we move from importance to chronology: "well, life existed prior to language, so without life there's no language." To that, I repeat myself:
a) It's not necessarily true that without life there's no language.
b) Without language (or some other, comparable expressive/cognitive mode) we couldn't even begin to comprehend what it would mean for life to come first, or exist without language.
