NOT

Is it possible to remove NOT from everyday spoken language? I think both answers "yes" and "no" are correct. Yes, I think I could remove it. No, I doubt I'd have enough time to catch it every time I think to use it. NOT is everywhere. Can I teach myself to duck when NOT comes hurtling toward my tongue? As compared with BUT, NOT has a role in logic -- and so in computer programming -- so it's possible to argue that it is an essential element for declaring things. (Actually, NOT can be set aside: all logical statements can be rendered without it; for that matter, they can be rendered with only a NAND or a NOR. NOT A = A NAND A). The easiest thing to see about how NOT works outside a computer and in the ears of a listener is that it rarely describes a small-enough chunk of the known world to do much good. If I say my keys are NOT here, that leaves the rest of the universe. That situation raises a question: what might be worthwhile to say as I make my way from place to place where my keys are NOT? I guess "I looked there already." Can I generalize this one rephrasing? Is there a universal NOT-removal technique?
