The instinct of simplification is an intelligent and sound one. Its satisfaction is a necessary preliminary to efficient action of any kind, and indeed the basis of all fruitful philosophy. But in criticism this instinct can only be satisfied intelligently and soundly by a consideration of everything appealing to consideration, and not at all by heated and wilful, or superior and supercilious, exclusions. Catholicity of appreciation is the secret of critical felicity. To follow the line of least resistance, not to take into account those elements of a problem, those characteristics of a subject, to which, superficially and at first thought, one is insensitive, is to dispense one’s self from a great deal of particularly disagreeable industry, but the result is only transitorily agreeable to the sincere intelligence. It is in criticism, I think, though no doubt in criticism alone, preferable to lose one’s self in a maze of perplexity—distressing as this is to the critic who appreciates the indispensability of clairvoyance in criticism—rather than to reach swiftly and simply a conclusion which candor would have foreseen as the inevitable and unjudicial result of following one’s own likes and whims, and one’s contentment with which must be alloyed with a haunting sense of insecurity. In criticism it is perhaps better to keep balancing counter-considerations than to determine brutally by excluding a whole set of them because of the difficulty of assigning them their true weight. In this way, at least, one preserves the attitude of poise, and poise is perhaps the one essential element of criticism. In a word, that catholicity of sensitiveness which may be called mere impressionism, behind which there is no body of doctrine at all, is more truly critical than intolerant depreciation or unreflecting enthusiasm. “The main thing to do,” says Mr. Arnold, in a significant passage, “is to get one’s self out of the way and let humanity judge.”
