Something may be judged by the amount of seriousness with which a thing is written. The air of sincerity which is inevitable in the genuine is most difficult to counterfeit. What a man really feels he writes with a certain earnestness which may seem indefinite, but which is sufficiently tangible in its effects upon the reader. More than by any other single influence mankind has in all its history been more affected by the contagion of belief; and it is not easy to exaggerate the susceptibility of humanity to this force. Vague and elusive as this test of the genuineness of emotion might seem, it is in reality capable of much practical application. We have no trouble in deciding that the conventional rhymes which fill the corners of the newspapers are not the product of genuine inner stress. We are too well acquainted with these time-draggled rhymes of "love" and "dove," of "darts" and "hearts," of "woe" and "throe;" we have encountered too often these pretty, petty fancies, these twilight musings and midnight moans, this mild melancholy and maudlin sentimentality. We have only to read these trig little bunches of verse, tied up, as it were, with sad-colored ribbons, to feel their artificiality. On the other hand, it is impossible to read "Helen of Kirconnel," or Browning's "Prospice," or Wordsworth's poems to Lucy, without being sure that the poet meant that which he said in his song with all the fervor of heart and imagination. A reader need not be very critical to feel that the novels of the "Duchess" and her tribe are made by a process as mechanical as that of making paper flowers; he will not be able to advance far in literary judgment without coming to suspect that fiction like the pleasant pot-boilers of William Black and W. Clark Russell, if hand-made, is yet manufactured according to an arbitrary pattern; but what reader can fail to feel that to Hawthorne "The Scarlet Letter" was utterly true, that to Thackeray Colonel Newcome was a creature warm with human blood and alive with a vigorous humanity? Theoretically we may doubt our power to judge of the sincerity of an author, but we do not find this so impossible practically.
