The Importance of Language

I'm trying to see how it can really sound. I love it for what it does for us. It wants to explain the pain and the glory, the nuances and the delicacies of our existence. And then it's so amusing. It allows us to laugh. But other than showing off language, isn't there other guiding principles? I mean, how about injustice for example? Would that be something? Oh, yes indeed. Injustice and cruelty. When I say how we are, I mean how human beings are,. How cruel we are, how kind we are... Language helps us to say that. That's why I love it.
