The instinct of congruity, of subordination of part to whole, the desire for harmony which is fostered above all things by art, is one of the most precious parts of our nature, if only, obeying its own tendency to expand, we apply it to ever wider circles of being; not merely to the accessories of living, but to life itself.

For this love of harmony and order leads us to seek what is most necessary in our living: a selection of the congruous, an arrangement of the mutually dependent in our thoughts and feelings.

Much of the work of the universe is done, no doubt, by what seems the exercise of mere random energy, by the thinking of apparently disconnected thoughts and the feeling of apparently sporadic impulses; but if the thought and the impulse remained really disconnected and sporadic, half would be lost and half would be distorted. It is one of the economical adaptations of nature that every part of us tends not merely to be consistent with itself, to eliminate the hostile, to beget the similar, but tends also to be connected with other parts; so that, action coming in contact with action, thought in contact with thought, and feeling in contact with feeling, each single one will be strengthened or neutralised by the other. And it is the especial business of what we may call the central consciousness, the dominant thought or emotion, to bring these separate thoughts and impulses, these separate groups thereof, into more complex relations, to continue on a far vaster scale that vital contact, that trying of all things by the great trial of affinity or repulsion, of congruity or incongruity. Thus we make trial of ourselves; and by the selfsame process, by the test of affinity and congruity, the silent forces of the universe make trial of us, rejecting or accepting, allowing us, our thoughts, our feelings to live and be fruitful, or condemning us and them to die in barrenness.

Whither are we going? In what shape shall the various members of our soul proceed on their journey; which forming the van, which the rear and centre? Or shall there be neither van, nor rear, nor wedge-like forward flight?

If this question remains unasked or unanswered, our best qualities, our truest thoughts and purest impulses, may be hopelessly scattered into distant regions, become defiled in bad company, or, at least, barren in isolation; the universal life rejecting or annihilating them.

How often do we not see this! Natures whose various parts have rambled asunder, or have come to live, like strangers in an inn, casually, promiscuously, each refusing to be his brother's keeper: instincts of kindliness at various ends, unconnected, unable to coalesce and conquer; thoughts separated from their kind, incapable of application; and, in consequence, strange superficial comradeships, shoulder-rubbings of true and false, good and evil, become indifferent to one another, incapable of looking each other in the face, careless, unblushing. Nay, worse. For lack of all word of command, of all higher control, hostile tendencies accommodating themselves to reign alternate, sharing the individual in distinct halves, till he becomes like unto that hero of Gautier's witch story, who was a pious priest one-half of the twenty-four hours and a wicked libertine the other: all power of selection, of reaction gone in this passive endurance of conflicting tendencies; all identity gone, save a mere feeble outsider looking on at the alternations of intentions and lapses, of good and bad. And the soul of such a person—if, indeed, we can speak of one soul or one person where there exists no unity—becomes like a jangle of notes belonging to different tonalities, alternating and mingling in hideous confusion for lack of a clear thread of melody, a consistent system of harmony, to select, reject, and keep all things in place.

Melody, harmony: the two great halves of the most purely æsthetic of all arts, symbolise, as we might expect, the two great forces of life: consecutiveness and congruity, under their different names of intention, fitness, selection, adaptation. These are what make the human soul like a conquering army, a fleet freighted with riches, a band of priests celebrating a rite. And this is what art, by no paltry formula, but by the indelible teaching of habit, of requirement, and expectation become part of our very fibre—this is what art can teach to those who will receive its highest lesson.

Those who can receive that lesson, that is to say, those in whom it can expand and ramify to the fulness and complexity which is its very essence. For it happens frequently enough that we learn only a portion of this truth, which by this means is distorted into error. We accept the æsthetic instinct as a great force of Nature; but, instead of acknowledging it as our master, as one of the great lords of life, of whom Emerson spoke, we try to make it our servant. We attempt to get congruity between the details of our everyday existence, and refuse to seek for congruity between ourselves and the life which is greater than ours.
