We are led to look in this direction by the startling thought with which the previous triplet closes. If the calamities bewailed are the chastisements of sin it is necessary for this sin to be sought out. The language of the elegist suggests that we are not aware of the nature of our own conduct, and that it is only by some serious effort that we can make ourselves acquainted with it, for this is what he implies when he represents the distressed people resolving to "search and try" their ways. Easy as it may seem in words, experience proves that nothing is more difficult in practice than to fulfil the precept of the philosopher, "Know thyself." The externalism in which most of our lives are spent makes the effort to look within a painful contradiction of habit. When it is attempted pride and prejudice face the inquirer, and too often quite hide the true self from view. If the pursuit is pushed on in spite of these hindrances the result may prove to be a sad surprise. Sometimes we see ourselves unexpectedly revealed, and then the sight of so great a novelty amazes us. The photographer's proof of a portrait dissatisfies the subject, not because it is a bad likeness, but rather because it is too faithful to be pleasing. A wonderful picture of Rossetti's represents a young couple who are suddenly confronted in a lonely forest by the apparition of their two selves as simply petrified with terror at the appalling spectacle. Even when the effort to acquire self-knowledge is strenuous and persevering, and accompanied by an honest resolution to accept the results, however unwelcome they may be, it often fails for lack of a standard of judgment. We compare ourselves with ourselves--our present with our past, or at best our actual life with our ideals. But this is a most illusory process, and its limits are too narrow. Or we compare ourselves with our neighbours--a possible advance, but still a most unsatisfactory method; for we know so little of them, all of us dwelling more or less like stars apart, and none of us able to sound the abysmal depths of another's personality. Even if we could fix this standard it too would be very illusory, because those people with whom we are making the comparison, quite as much as we ourselves, may be astray, just as a whole planetary system, though perfectly balanced in the mutual relations of its own constituent worlds, may yet be out of its orbit, and rushing on all together towards some awful common destruction.
