It may well be that the chemist or physiologist is right when he decides that he will become a better chemist or physiologist if he concentrates on his subject at the expense of his general education. But in the study of society exclusive concentration on a speciality has a peculiarly baneful effect: it will not merely prevent us from being attractive company or good citizens but may impair our competence in our proper field — or at least for some of the most important tasks we have to perform. The physicist who is only a physicist can still be a first class physicist and a most valuable member of society. But nobody can be a great economist who is only an economist — and I am even tempted to add that the economist who is only an economist is likely to become a nuisance if not a positive danger.
