--It is n't help I want, it is removing hindrances. I don't want to see anything to draw off my attention. I don't want a cornice, or an angle, or anything but a containing curve. I want diffused light and no single luminous centre to fix my eye, and so distract my mind from its one object of contemplation. The metaphysics of attention have hardly been sounded to their depths. The mere fixing the look on any single object for a long time may produce very strange effects. Gibbon's well-known story of the monks of Mount Athos and their contemplative practice is often laughed over, but it has a meaning. They were to shut the door of the cell, recline the beard and chin on the breast, and contemplate the abdominal centre. “At first all will be dark and comfortless; but if you persevere day and night, you will feel an ineffable joy; and no sooner has the soul discovered the place of the heart, than it is involved in a mystic and ethereal light.” And Mr. Braid produces absolute anaesthesia, so that surgical operations can be performed without suffering to the patient, only by making him fix his eyes and his mind on a single object; and Newton is said to have said, as you remember, “I keep the subject constantly before me, and wait till the first dawnings open slowly by little and little into a full and clear light.” These are different, but certainly very wonderful, instances of what can be done by attention. But now suppose that your mind is in its nature discursive, erratic, subject to electric attractions and repulsions, volage; it may be impossible for you to compel your attention except by taking away all external disturbances. I think the poets have an advantage and a disadvantage as compared with the steadier-going people. Life is so vivid to the poet, that he is too eager to seize and exhaust its multitudinous impressions. Like Sindbad in the valley of precious stones, he wants to fill his pockets with diamonds, but, lo! there is a great ruby like a setting sun in its glory, and a sapphire that, like Bryant's blue gentian, seems to have dropped from the cerulean walls of heaven, and a nest of pearls that look as if they might be unhatched angel's eggs, and so he hardly knows what to seize, and tries for too many, and comes out of the enchanted valley with more gems than he can carry, and those that he lets fall by the wayside we call his poems. You may change the image a thousand ways to show you how hard it is to make a mathematician or a logician out of a poet. He carries the tropics with him wherever he goes; he is in the true sense felius naturae, and Nature tempts him, as she tempts a child walking through a garden where all the finest fruits are hanging over him and dropping round him, where The luscious clusters of the vine Upon (his) mouth do crush their wine, The nectarine and curious peach, Into (his) hands themselves do reach;
