So, if we have loved beauty well, have seen in it a promise of ultimate joy, a sign of a deliberate intention, a message from a power that does not send sorrow and anxiety wantonly, cruelly and indifferently, an assurance of something that waits to welcome and bless us, then beauty is not a mere torturing menace, a heartless and unkind parading of joy which we cannot feel, but a faithful pledge of something secure and everlasting, which will return to us again and again in ever fuller measure, even if the flow of it be sometimes suspended. We ought then to train and practise our sense of beauty, not selfishly and luxuriously, but so that when the dark hour comes it may help us to realise that all is not lost, may alleviate our pain by giving us the knowledge that the darkness is the interruption, but that the joy is permanent and deep and certain. Thus beauty, instead of being for us but as the melody swiftly played when our hearts are high, a mere momentary ray, a happy accident that befalls us, may become to us a deep and vital spring of love and hope, of which we may say that it is there waiting for us, like the home that awaits the traveller over the weary upland at the foot of the far-looming hill. It may come to us as a perpetual sign that we are not forgotten, and that the joy of which it makes mention survives all interludes of strife and uneasiness. It is easy to slight and overlook it, but if we do that, we are deluded by the passing storm into believing that confusion and not peace is the end. As George Meredith nobly wrote, during the tragic and fatal illness of his wife, "Here I am in the very pits of tragic life.... Happily for me, I have learnt to live much in the spirit, and see brightness on the other side of life, otherwise this running of my poor doe with the inextricable arrow in her flanks would pull me down too." The spirit, the brightness of the other side, that is the secret which beauty can communicate, and the message which she bears upon her radiant wings. XXVI THE PRINCIPLE OF BEAUTY "I have loved," said Keats, "the _principle_ of beauty in all things." It is that to which all I have said has been leading, as many roads unite in one. We must try to use discrimination, not to be so optimistic that we see beauty if it is not there, not to overwhelm every fling that every craftsman has at beauty with gush and panegyric; not to praise beauty in all companies, or to go off like a ripe broom-pod, at a touch. When Walter Pater was confronted with something which courtesy demanded that he should seem to admire, he used to say in that soft voice of his, which lingered over emphatic syllables, "Very costly, no doubt!"
