But Mr Arnold did not agree with these severe folk. He thought--and not a few good wits have thought with him--not only that these Introductions are an opportunity for men like himself, with original gifts of thought and style, to display these gifts, but that the mighty public, for all its knowledge of everything that has been thought and said about everybody, might find something new to it even in the observations of lesser folk. As a matter of fact, of course, and neither to talk nor to quote nonsense, the utility of such Introductions, even if moderately well done, is unmistakable. Not one in a thousand of the probable readers of any book has all the information which even a fairly competent introducer will put before him; not one in a hundred knows the previous estimates of the author; not many possess that acquaintance with his whole work which it is part of the business of the introducer to acquire, and adjust for the better understanding of the particular book. Of course, if an Introduction is imperfectly furnished with fact and thought and reading--if it is desultory, in bad taste, and so forth--it had better not be there. But this is only saying that a bad Introduction is a bad thing, which does not get us much beyond the intellectual edification of the niece of Gorboduc. Unless the introducer is a boggler, the Introduction will probably do good to those who want it and can be neglected by those who don't; while in the rarer and better cases it will itself acquire, or even possess from the first, that very value as a _point de repere_ which Mr Arnold had discussed. It will be good relatively and good in itself,--a contribution at once to the literature of knowledge and to the literature of power.
