It’s talked about quite a lot. Obama ran on it, but I have yet to hear anyone ever specify; FROM WHAT, TO WHAT. To hear someone embrace “Change” without specifying “from what and to what” is more than a little disturbing. It has to mean that you believe things to be so bad right now that they can’t get any worse, and that therefore ANY change will be for the better. I’ll have to assume that you’re motivated purely by angst, and that will never turn out well.
Change means you’re moving away from some particular situation or condition, and toward some other situation or condition. If you’re going to advocate unspecified change, or talk about changing the world as though it should be taken as a given that changing the world would be a good thing, then you’re insane. Simple as that.
If you’re telling me you want to change the world, you’d best be specific as to what you believe is wrong with it right now, and be specific about your premises, ideals and goals. Then we have something to discuss. Otherwise I have no time for you.
