Perhaps one of the greatest mistakes we make in literature and art is the passionate individualism into which we are betrayed. We cannot bring ourselves to speak or think very highly of the level of a man's work, unless the positive and tangible results of that work are in themselves very weighty and pure. We forget all about the inspirers and teachers of poets and artists. How often does the poet, and the artist too, in autobiographical allusion, speak with absorbing gratitude and devotion of some humble name of which we take no note, as the "fons et origo" to himself of enthusiasm and proficiency. It is with no affectation of fastidious superiority, but with a frank confession of conscious pettiness, that I say that this book will only appeal to a few. The critic is no hero: he is at best but a skipping peltast, engaged as often as not in inglorious flight. To flounder in images, criticism is nothing but a species of mistletoe, sprouting in a sleek bunch in the chink of a lofty forest tree. I had rather have been Lovelace than Sainte-Beuve, and write one immortal lyric than thirty-five volumes of the acutest discrimination. But a minority has a right to its opinions, and may claim to be amused: a man who thinks the Rhine vulgar, and the Jungfrau exaggerated, may be foolishly delighted with a backwater on the Thames, and a view of the Berkshire downs. In fact, the only kind of criticism of which one may be impatient is the criticism which abuses an author for not writing something else. What critics can do, what I have attempted to do, is to strengthen and define the impression that a casual reader may derive from a book, a reader who wishes to see what is good, but has not the knack described by the poet, who says "what is best he firmly lights upon, as birds on sprays." On the other hand we may reasonably doubt what is the exact worth of the cultivation, of the point of view which we meekly accept at the hands of a convincing critic. Does it not require a special insight to understand even criticism? After all, we agree with, we do not accept criticism: we select from it some preference, strongly and convincingly stated, which jumps with our own preconceived ideas. If we merely swallow it down, like the camel, to be reproduced in fetid stagnation, whenever a necessity for it arises, are we so much higher after all? The delicate psychologist who has accepted my dedication, speaks in one of his latest stories of the expression on the face of a Royal Princess, who had been _told_ everything in the world, and had never _perceived_ anything. Culture, criticism, in certain sterile natures, are like Sheridan's famous apophthegm: they lie "like lumps of marl on a barren moor, encumbering what it is not in their power to fertilise."
