The habit of beauty, of harmony, is but the habit, engrained in our nature by the unnoticed experiences of centuries, of life in our surroundings and in ourselves; the habit of beauty is the habit, I believe scientific analysis of nature's ways and means will show us—of the growing of trees, the flowing of water, the perfect play of perfect muscles, all registered unconsciously in the very structure of our soul. And for this reason every time we experience afresh the particular emotion associated with the quality beautiful, we are adding to that rhythm of life within ourselves by recognising the life of all things. There is not room within us for two conflicting waves of emotion, for two conflicting rhythms of life, one sane and one unsound. The two may possibly alternate, but in most cases the weaker will be neutralised by the stronger; and, at all events, they cannot co-exist. We can account, only in this manner, for the indisputable fact that great emotion of a really and purely æsthetic nature has a morally elevating quality, that as long as it endures—and in finer organisations its effect is never entirely lost—the soul is more clean and vigorous, more fit for high thoughts and high decisions. All understanding, in the wider and more philosophical sense, is but a kind of becoming: our soul experiences the modes of being which it apprehends. Hence the particular religious quality (all faiths and rituals taking advantage thereof) of a high and complex æsthetic emotion. Whenever we come in contact with real beauty, we become aware, in an unformulated but overwhelming manner, of some of the immense harmonies of which all beauty is the product, of which all separate beautiful things are, so to speak, the single patterns happening to be in our line of vision, while all around other patterns connect with them, meshes and meshes of harmonies, spread out, outside our narrow field of momentary vision, an endless web, like the constellations which, strung on their threads of mutual dependence, cover and fill up infinitude.
In the moments of such emotional perception, our soul also, ourselves, become in a higher degree organic, alive, receiving and giving out the life of the universe; come to be woven into the patterns of harmonies, made of the stuff of reality, homogeneous with themselves, consubstantial with the universe, like the living plant, the flowing stream, the flying cloud, the great picture or statue.
And in this way is realised, momentarily, but with ever-increasing power of repetition, that which, after the teaching of Diotima, Socrates prayed for—"the harmony between the outer and the inner man."
But this, I know, many will say, is but a delusion. Rapture is pleasant, but it is not necessarily, as the men of the Middle Ages thought, a union with God. And is this the time to revive, or seek to revive, when science is for ever pressing upon us the conclusion that soul is a function of matter—is this the time to revive discredited optimistic idealisms of an unscientific philosophy?
But if science become omniscient, it will surely recognise and explain the value of such recurring optimistic idealisms; and if the soul be a function of matter, will not science recognise but the more, that the soul is an integral and vitally dependent portion of the material universe?

Be this as it may, one thing seems certain, that the artistic activities are those which bring man into emotional communion with external nature; and that such emotional communion is necessary for man's thorough spiritual health. Perception of cause and effect, generalisation of law, reduces the universe indeed to what man's intellect can grasp; but in the process of such reduction to the laws of man's thought, the universe is shorn of its very power to move man's emotion and overwhelm his soul. The abstract which we have made does not vivify us sufficiently. And the emotional communion of man with nature is through those various faculties which we call æsthetic. It is not to no purpose that poetry has for ever talked to us of skies and mountains and waters; we require, for our soul's health, to think about them otherwise than with reference to our material comfort and discomfort; we require to feel that they and ourselves are brethren united by one great law of life. And what poetry suggests in explicit words, bidding us love and be united in love to external nature; art, in more irresistible because more instinctive manner, forces upon our feelings, by extracting, according to its various kinds, the various vital qualities of the universe, and making them act directly upon our mind: rhythms of all sorts, static and dynamic, in the spatial arts of painting and sculpture; in the half spatial, half temporal art of architecture: in music, which is most akin to life, because it is the art of movement and change.

We can all remember moments when we have seemed conscious, even to overwhelming, of this fact. In my own mind it has become indissolubly connected with a certain morning at Venice, listening to the organ in St. Mark's.
