I would argue in favor of the widest possible diffusion of knowledge of all the possibilities among physicists. At a time like this, physicists ought to know of all the possibilities, and to feel that while they do not know which of these are correct, they must be ready, if necessary, to abandon even what seemed most secure and beautiful in the old point of view, in favor of what may seem arbitrary and ugly in the new point of view, if this should help explain something.
