The senses report the new fact or change; the mind discovers some essential copula binding this fact or change to a class of facts or changes, and enjoys the discovery as if coming to its own again. A perception is always a generalization. It lifts the object, whether in material or moral nature, into a type. The animal, the low degrees of intellect, know only individuals. The philosopher knows only laws. That is, he considers a purely mental fact, part of the soul itself. We say with Kenelm Digby, “All things that she knoweth are herself, and she is all that she knoweth.” Insight assimilates the thing seen. Is it only another way of affirming and illustrating this to say that it sees nothing alone, but sees each particular object in just connections,—sees all in God? In all healthy souls is an inborn necessity of presupposing for each particular fact a prior Being which compels it to a harmony with all other natures. The game of Intellect is the perception that whatever befalls or can be stated is a universal proposition; and contrariwise, that every general statement is poetical again by being particularized or impersonated.
A single thought has no limit to its value; a thought, properly speaking,—that is a truth held not from any man’s saying so, or any accidental benefit or recommendation it has in our trade or circumstance, but because we have perceived it is a fact in the nature of things, and in all times and places will and must be the same thing,—is of inestimable value. Every new impression on the mind is not to be derided, but is to be accounted for, and, until accounted for, registered as an indisputable addition to our catalogue of natural facts.
The first fact is the fate in every mental perception,—that my seeing this or that, and that I see it so or so, is as much a fact in the natural history of the world as is the freezing of water at thirty-two degrees of Fahrenheit. My percipiency affirms the presence and perfection of law, as much as all the martyrs. A perception, it is of a necessity older than the sun and moon, and the Father of the Gods. It is there with all its destinies. It is its nature to rush to expression, to rush to embody itself. It is impatient to put on its sandals and be gone on its errand, which is to lead to a larger perception, and so to new action. For thought exists to be expressed. That which cannot externize itself is not thought.
Do not trifle with your perceptions, or hold them cheap. They are your door to the seven heavens, and if you pass it by you will miss your way. Say, what impresses me ought to impress me. I am bewildered by the immense variety of attractions and cannot take a step; but this one thread, fine as gossamer, is yet real; and I hear a whisper, which I dare trust, that it is the thread on which the earth and the heaven of heavens are strung.
The universe is traversed by paths or bridges or stepping-stones across the gulfs of space in every direction. To every soul that is created is its path, invisible to all but itself. Each soul, therefore, walking in its own path walks firmly; and to the astonishment of all other souls, who see not its path, it goes as softly and playfully on its way as if, instead of being a line, narrow as the edge of a sword, over terrific pits right and left, it were a wide prairie.
Genius is a delicate sensibility to the laws of the world, adding the power to express them again in some new form. The highest measure of poetic power is such insight and faculty to fuse the circumstances of to-day as shall make transparent the whole web of circumstance and opinion in which the man finds himself, so that he releases himself from the traditions in which he grew,—no longer looks back to Hebrew or Greek or English use or tradition in religion, laws, or life, but sees so truly the omnipresence of eternal cause that he can convert the daily and hourly event of New York, of Boston, into universal symbols. I owe to genius always the same debt, of lifting the curtain from the common and showing me that gods are sitting disguised in every company.
The conduct of Intellect must respect nothing so much as preserving the sensibility. My measure for all subjects of science as of events is their impression on the soul. That mind is best which is most impressionable. There are times when the cawing of a crow, a weed, a snow-flake, a boy’s willow whistle, or a farmer planting in his field is more suggestive to the mind than the Yosemite gorge or the Vatican would be in another hour. In like mood an old verse, or certain words, gleam with rare significance.
But sensibility does not exhaust our idea of it. That is only half. Genius is not a lazy angel contemplating itself and things. It is insatiable for expression. Thought must take the stupendous step of passing into realization. A master can formulate his thought. Our thoughts at first possess us. Later, if we have good heads, we come to possess them. We believe that certain persons add to the common vision a certain degree of control over these states of mind; that the true scholar is one who has the power to stand beside his thoughts or to hold off his thoughts at arm’s length and give them perspective.
It is not to be concealed that the gods have guarded this privilege with costly penalty. This slight discontinuity which perception effects between the mind and the object paralyzes the will. If you cut or break in two a block or stone and press the two parts closely together, you can indeed bring the particles very near, but never again so near that they shall attract each other so that you can take up the block as one. That indescribably small interval is as good as a thousand miles, and has forever severed the practical unity. Such is the immense deduction from power by discontinuity.
