As humans, we must ask this of ourselves. Are there things we cannot change about ourselves, be they personal, societal, etc?
I always think about this question and how unusual it is that people create some constant, and decide that there is nothing that can or will ever be done about it. For example; "there will always be good people and bad people in the world." Though it's very general, it's also matter-of-fact regardless of its assumption.
Most people would agree with it, though. Hell, I'd agree with it, but agreeing with it makes me wonder about how I define good and bad. If I think about it long enough, I don't really agree with it, because people aren't just born "bad." There are things we can do to make people want to do "good," (not including threats or punishment,) and there are things which make people want to do "bad." Both exist in our world, and since there are so many opinions to be had, it's almost like there's no such thing as "right" or "wrong," and thus, "good" or "bad." "There will always be different kinds of people with different perceptions in the world," is a much more concrete reality.
This can go for groups of people, ideas, and anything that can be judged. However, we like to judge ourselves and each other more than anything, don't we?
I've been "apocalyptic" for some time now. That is, I don't believe my people on this good earth will be able to prolong their existence on it for much longer. I've made this judgement, and I've made judgments about all the humans that ever existed, for that matter. It's a broad judgement and it's not a progressive one. What I mean is, I believe that my species is destructive at heart ("for the most part," because while some of us would like to change this, our surroundings and excuses prevent us from doing so.)
We are the dominant species on this planet. We pretty much get to decide what stays and goes, and it's always to our convenience. We think we're damn special, and we like to consider ourselves the most intelligent being we know of as well. So of course, anything we do or want to do takes priority over all else. We are no longer merely beings, we are emperors, say many cultures (including and especially my own,) and there will be no interfering with our growth.
This is the concrete reality that has been forged in our hands and branded on our backs. This, and many other realities, are things we'd be stupid to argue with because they're "in our best interest" and we "need them to survive comfortably."
More on this later, I've had a fever for the past week or I'd post more now that school's started!
