Languages are more than just words. They express a world view. Some are loose and ambiguous, others technical and precise. Our languages reflect our environmental and social origins.
Behavior is a form of language. We say a lot through our attitude, approach, and actions. By attitude I mean reason vs superstition, by approach I mean tolerance vs prejudice, and by action I mean cooperation vs aggression.
If we extend our description of language to include "language as behavior", we might imagine a language of peace versus a language of violence. What might the environmental and social origins of a language of violence be? I imagine a world of fear, treachery, and hate, where dishonesty and coercion are rewarded. I pity the inhabitants of such a place but I don't want to join them.
We now live in a land occupied by the speakers of the language of violence. They don't understand us when we talk about reason tolerance, and cooperation. To communicate with speakers of another language, one side must learn the language of the other. If they are unwilling to learn ours, then we must learn theirs.
We don't want to adopt the language of violence as our own, but to communicate with our oppressors we will need to learn it. And having acquired this vocabulary, we must speak with clarity, precision and finality. When our point is made and we are free once again, only then can we return to the language of peace. In that future time we must search our hearts and our history. We need to understand how we allowed evil to grow unchecked and ask our children to forgive us for the wrongs we did in our fight against it.
