"I don't know what weapons will be used in World War III, but World War IV will be fought with sticks and stones."

{- Albert Einstein}

Einstein envisioned that World War III would be so devastating that the technology and civilization we know would be destroyed, and the survivors would have to return to primitive times.

However, it seems that humanity has always been primitive, whether modern or not, technological or not; its use has always been clearly opposed to its purpose.
