「All knowledge is for good. Only the use to which you put it can be good or evil.」
「I believe that time is like an endless motorway with an infinite number of lanes all running from the past into the future. A driver could change his lanes. lt follows that a driver could change his lanes and change his future. If you left this room right now, you might wind up shot dead. If you left a minute later, you might survive. It's a blind choice, but you can change lanes.」
