Eric Hoffer attributed this quote to Hitler in the book “True Believer”. To quote the book-“When Hitler was asked whether he thought the Jew must be destroyed, he answered: “No-we should then have to invent him. It is essential to have a tangible enemy, not merely an abstract one.”” This appears in the 14th Chapter of the book, 65th passage. Hoffer uses this quote as an explanation of the need of a common subject of hatred in order to unify disparate elements(in this case the German people). Hoffer reference source was Hermann Rauschning “Hitler Speaks” New York: G.P. Putnam’s Sons, 1940), p. 234.
You should read up more on Jewish philosophy. The Jewish faith is dogmatic, but not at all impractical. While it would be against scripture to use an electric device in the sabbath, it would be a greater shame still for anybody to miss the sabbath services because they can’t mount ten flights of stairs, hence elevators are allowed to run during sabbath as a compromise. Likewise, using a car during sabbath would be against scripture, but according to many orthodox scholars it’s allowed in order to attend a service, if not using a car would mean that one missed it.
Definitely not. I believe that the Conservative movement allows for the use of cars to drive to services, but the universal Orthodox position is that it’s better to pray at home by oneself than to drive to services, and that the only time it’s acceptable to drive on the Sabbath is to save a life. According to most Orthodox opinions, one can have an elevator that runs automatically (eg stopping on every other floor of a tall building for ten seconds, without any human intervention), but one can’t actually control the elevator. (The minority bans the use of such elevators entirely, and nobody Orthodox permits them in the manner you outlined.)
