My own view is that these arrangements are good for both readers  since they can be fairly certain the reviewer has at least some idea what he is talking about  and professors if only because the work helps to keep them sane It also reminds them that they have a duty easily neglected to make themselves intelligible to nonprofessors When talking among themselves they may feel some need to be impressively arcane but when addressing intelligent nonprofessors they need to make sure they are communicating effectively
