In inquiries respecting the laws of the world and the frame of things, the highest reason is always the truest. That which seems faintly possible — it is so refined, is often faint and dim because it is deepest seated in the mind among the eternal verities. Empirical science is apt to cloud the sight, and, by the very knowledge of functions and processes, to bereave the student of the manly contemplation of the whole. The savant becomes unpoetic. But the best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn of his relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known quantities, but is arrived at by untaught sallies of the spirit, by a continual self-recovery, and by entire humility. He will perceive that there are far more excellent qualities in the student than preciseness and infallibility; that a guess is often more fruitful than an indisputable affirmation, and that a dream may let us deeper into the secret of nature than a hundred concerted experiments.

For, the problems to be solved are precisely those which the physiologist and the naturalist omit to state. It is not so pertinent to man to know all the individuals of the animal kingdom, as it is to know whence and whereto is this tyrannizing unity in his constitution, which evermore separates and classifies things, endeavoring to reduce the most diverse to one form. When I behold a rich landscape, it is less to my purpose to recite correctly the order and superposition of the strata, than to know why all thought of multitude is lost in a tranquil sense of unity. I cannot greatly honor minuteness in details, so long as there is no hint to explain the relation between things and thoughts; no ray upon the metaphysics of conchology, of botany, of the arts, to show the relation of the forms of flowers, shells, animals, architecture, to the mind, and build science upon ideas. In a cabinet of natural history, we become sensible of a certain occult recognition and sympathy in regard to the most unwieldly and eccentric forms of beast, fish, and insect. The American who has been confined, in his own country, to the sight of buildings designed after foreign models, is surprised on entering York Minster or St. Peter’s at Rome, by the feeling that these structures are imitations also, — faint copies of an invisible archetype. Nor has science sufficient humanity, so long as the naturalist overlooks that wonderful congruity which subsists between man and the world; of which he is lord, not because he is the most subtile inhabitant, but because he is its head and heart, and finds something of himself in every great and small thing, in every mountain stratum, in every new law of color, fact of astronomy, or atmospheric influence which observation or analysis lay open. A perception of this mystery inspires the muse of George Herbert, the beautiful psalmist of the seventeenth century. The following lines are part of his little poem on Man.

“Man is all symmetry,
Full of proportions, one limb to another,
And to all the world besides.
Each part may call the farthest, brother;
For head with foot hath private amity,
And both with moons and tides.

“Nothing hath got so far
But man hath caught and kept it as his prey;
His eyes dismount the highest star;
He is in little all the sphere.
Herbs gladly cure our flesh, because that they
Find their acquaintance there.

“For us, the winds do blow,
The earth doth rest, heaven move, and fountains flow;
Nothing we see, but means our good,
As our delight, or as our treasure;
The whole is either our cupboard of food,
Or cabinet of pleasure.

“The stars have us to bed:
Night draws the curtain; which the sun withdraws.
Music and light attend our head.
All things unto our flesh are kind,
In their descent and being; to our mind,
In their ascent and cause.

“More servants wait on man
Than he’ll take notice of. In every path,
He treads down that which doth befriend him
When sickness makes him pale and wan.
Oh mighty love! Man is one world, and hath
Another to attend him.”

The perception of this class of truths makes the attraction which draws men to science, but the end is lost sight of in attention to the means. In view of this half-sight of science, we accept the sentence of Plato, that, “poetry comes nearer to vital truth than history.” Every surmise and vaticination of the mind is entitled to a certain respect, and we learn to prefer imperfect theories, and sentences, which contain glimpses of truth, to digested systems which have no one valuable suggestion. A wise writer will feel that the ends of study and composition are best answered by announcing undiscovered regions of thought, and so communicating, through hope, new activity to the torpid spirit.

I shall therefore conclude this essay with some traditions of man and nature, which a certain poet sang to me; and which, as they have always been in the world, and perhaps reappear to every bard, may be both history and prophecy.

‘The foundations of man are not in matter, but in spirit. But the element of spirit is eternity. To it, therefore, the longest series of events, the oldest chronologies are young and recent. In the cycle of the universal man, from whom the known individuals proceed, centuries are points, and all history is but the epoch of one degradation.

‘We distrust and deny inwardly our sympathy with nature. We own and disown our relation to it, by turns. We are, like Nebuchadnezzar, dethroned, bereft of reason, and eating grass like an ox. But who can set limits to the remedial force of spirit?

‘A man is a god in ruins. When men are innocent, life shall be longer, and shall pass into the immortal, as gently as we awake from dreams. Now, the world would be insane and rabid, if these disorganizations should last for hundreds of years. It is kept in check by death and infancy. Infancy is the perpetual Messiah, which comes into the arms of fallen men, and pleads with them to return to paradise.

‘Man is the dwarf of himself. Once he was permeated and dissolved by spirit. He filled nature with his overflowing currents. Out from him sprang the sun and moon; from man, the sun; from woman, the moon. The laws of his mind, the periods of his actions externized themselves into day and night, into the year and the seasons. But, having made for himself this huge shell, his waters retired; he no longer fills the veins and veinlets; he is shrunk to a drop. He sees, that the structure still fits him, but fits him colossally. Say, rather, once it fitted him, now it corresponds to him f............
