Perhaps the reader may not feel in these papers that inner solidarity which the writer is conscious of; and it is in this doubt that the writer wishes to offer a word of explanation. He owns, as he must, that they have every appearance of a group of desultory sketches and essays, without palpable relation to one another, or superficial allegiance to any central motive. Yet he ventures to hope that the reader who makes his way through them will be aware, in the retrospect, of something like this relation and this allegiance.
