In my opinion, if, as the result of certain combinations, Kepler's or Newton's discoveries could become known to people in no other way than by sacrificing the lives of one, or ten, or a hundred or more people who were hindering the discovery, or standing as an obstacle in its path, then Newton would have the right, and it would even be his duty to remove those ten or a hundred people, in order to make his discoveries known to mankind. It by no means follows from this, incidentally, that Newton should have the right to kill anyone he pleases, whomever happens along, or to steal from the market every day.
