When once a book has become immortal, we think that we can see why it became so. It contained, we perceive, a casting of thought which could not but arrest and retain men’s attention; it said some things once and for all because it gave them their best expression. Or else it spoke with a grace or with a fire of imagination, with a sweet cadence of phrase and a full harmony of tone, which have made it equally dear to all generations of those who love the free play of fancy or the incomparable music of perfected human speech. Or perhaps it uttered with candor and simplicity some universal sentiment; perchance pictured something in the tragedy or the comedy of man’s life as it was never pictured before, and must on that account be read and read again as not to be superseded. There must be something special, we judge, either in its form or in its substance, to account for its unwonted fame and fortune. This upon first analysis, taking one book at a time. A look deeper into the heart of the matter enables us to catch at least a glimpse of a single and common source of immortality. The world is attracted by books as each man is attracted by his several friends. You recommend that capital fellow So-and-So to the acquaintance of others because of his discriminating and diverting powers of observation: the very tones and persons--it would seem the very selves--of every type of man live again in his mimicries and descriptions. He is the dramatist of your circle; you can never forget him, nor can any one else; his circle of acquaintances can never grow smaller. Could he live on and retain perennially that wonderful freshness and vivacity of his, he must become the most famous guest and favorite of the world. Who that has known a man quick and shrewd to see dispassionately the inner history, the reason and the ends, of the combinations of society, and at the same time eloquent to tell of them, with a hold on the attention gained by a certain quaint force and sagacity resident in no other man, can find it difficult to understand why we still resort to Montesquieu? Possibly there are circles favored of the gods who have known some fellow of infinite store of miscellaneous and curious learning, who has greatly diverted both himself and his friends by a way peculiar to himself of giving it out upon any and all occasions, item by item, as if it were all homogeneous and of a piece, and by his odd skill in making unexpected application of it to out-of-the-way, unpromising subjects, as if there were in his view of things mental no such disintegrating element as incongruity. Such a circle would esteem it strange were Burton not beloved of the world. And so of those, if any there be, who have known men of simple, calm, transparent natures, untouched by storm or perplexity, whose talk was full of such serious, placid reflection as seemed to mirror their own reverent hearts,--talk often prosy, but more often touchingly beautiful, because of its
