College professors differ in their opinions much as other men do, and sometimes even more vehemently. The Boston newspapers have recently been giving prominence to a marked divergence of opinion on the part of two Harvard teachers with reference to the Boston police strike.

Mr. Harold J. Laski, whose radical opinions have given him a good deal of publicity, is, it might be explained, a young Englishman who has served the University during the past two or three years as a lecturer on history and a tutor in the Division of History, Government and Economics. During the current year he is giving lectures at Yale also. The brilliancy of his intellect and his capacity as a teacher are generally recognized, but his views on social and political topics run far afield from those which have usually been accounted orthodox, and his recent utterances on the Boston police strike have been hotly challenged by some of his colleagues, as they doubtless will be by many of the alumni.

It should be pointed out that in discussing these matters outside his classroom and in expressing whatever views he may hold on this or any other subject of current public policy, Mr. Laski is utilizing a privilege which Harvard has steadfastly accorded to all her teachers. As President Lowell declared some years ago, a university cannot exercise a censorship over the utterances of its teachers without accepting responsibility for everything they do or say. It might not be amiss to suggest to Mr. Laski, however, that, as he is not a citizen of the United States, the amenities of the situation would seem to call for a reasonable measure of restraint in the criticism of our public officials. This is a sphere in which the average American is inclined to be very resentful of aspersion that comes from alien lips. HARVARD ALUMNI BULLETIN.
