We are delicate machines, and require nice treatment to get from us the maximum of power and pleasure. We need tonics, but must have those that cost little or no reaction. The flame of life burns too fast in pure oxygen, and nature has tempered the air with nitrogen. So thought is the native air of the mind, yet pure it is a poison to our mixed constitution, and soon burns up the bone-house of man, unless tempered with affection and coarse practice in the material world. Varied foods, climates, beautiful objects,—and especially the alternation of a large variety of objects—are the necessity of this exigent system of ours. But our tonics, our luxuries, are force-pumps which exhaust the strength they pretend to supply; and of all the cordials known to us, the best, safest, and most exhilarating, with the least harm, is society; and every healthy and efficient mind passes a large part of life in the company most easy to him.

We seek society with very different aims, and the staple of conversation is widely unlike in its circles. Sometimes it is facts,—running from those of daily necessity to the last results of science,—and has all degrees of importance; sometimes it is love, and makes the balm of our early and of our latest days; sometimes it is thought, as from a person who is a mind only; sometimes a singing, as if the heart poured out all like a bird; sometimes experience. With some men it is a debate; at the approach of a dispute they neigh like horses. Unless there be an argument, they think nothing is doing. Some talkers excel in the precision with which they formulate their thoughts, so that you get from them somewhat to remember; others lay criticism asleep by a charm. Especially women use words that are not words,—as steps in a dance are not steps,—but reproduce the genius of that they speak of; as the sound of some bells makes us think of the bell merely, whilst the church-chimes in the distance bring the church and its serious memories before us. Opinions are accidental in people,—have a poverty-stricken air. A man valuing himself as the organ of this or that dogma is a dull companion enough; but opinion native to the speaker is sweet and refreshing, and inseparable from his image. Neither do we by any means always go to people for conversation. How often to say nothing,—and yet must go; as a child will long for his companions, but among them plays by himself. ’Tis only presence which we want. But one thing is certain,—at some rate, intercourse we must have. The experience of retired men is positive,—that we lose our days and are barren of thought for want of some person to talk with. The understanding can no more empty itself by its own action than can a deal box.

The clergyman walks from house to house all day all the year to give people the comfort of good talk. The physician helps them mainly in the same way, by healthy talk giving a right tone to the patient’s mind. The dinner, the walk, the fireside, all have that for their main end.

See how Nature has secured the communication of knowledge. ’Tis certain that money does not more burn in a boy’s pocket than a piece of news burns in our memory until we can tell it. And, in higher activity of mind, every new perception is attended with a thrill of pleasure, and the imparting of it to others is also attended with pleasure. Thought is the child of the intellect, and this child is conceived with joy and born with joy.

Conversation is the laboratory and workshop of the student. The affection or sympathy helps. The wish to speak to the want of another mind assists to clear your own. A certain truth possesses us, which we in all ways strive to utter. Every time we say a thing in conversation, we get a mechanical advantage in detaching it well and delivery. I prize the mechanics of conversation. ’Tis pulley and lever and screw. To fairly disengage the mass, and send it jingling down, a good boulder,—a block of quartz and gold, to be worked up at leisure in the useful arts of life,—is a wonderful relief.

What are the best days in memory? Those in which we met a companion who was truly such. How sweet those hours when the day was not long enough to communicate and compare our intellectual jewels,—the favorite passages of each book, the proud anecdotes of our heroes, the delicious verses we had hoarded! What a motive had then our solitary days! How the countenance of our friend still left some light after he had gone! We remember the time when the best gift we could ask of fortune was to fall in with a valuable companion in a ship’s cabin, or on a long journey in the old stage-coach, where, each passenger being forced to know every other, and other employments being out of question, conversation naturally flowed, people became rapidly acquainted, and, if well adapted, more intimate in a day than if they had been neighbors for years.

In youth, in the fury of curiosity and acquisition, the day is too short for books and the crowd of thoughts, and we are impatient of interruption. Later, when books tire, thought has a more languid flow; and the days come when we are alarmed, and say there are no thoughts. ‘What a barren-witted pate is mine!’ the student says; ‘I will go and learn whether I have lost my reason.’ He seeks intelligent persons, whether more wise or less wise than he, who give him provocation, and at once and easily the old motion begins in his brain: thoughts, fancies, humors flow; the cloud lifts; the horizon broadens; and the infinite opulence of things is again shown him. But the right conditions must be observed. Mainly he must have leave to be himself. Sancho Panza blessed the man who invented sleep. So I prize the good invention whereby everybody is provided with somebody who is glad to see him.

If men are less when together than they are alone, they are also in some respects enlarged. They kindle each other; and such is the power of suggestion, that each sprightly story calls out more; and sometimes a fact that had long slept in the recesses of memory hears the voice, is welcomed to daylight, and proves of rare value. Every metaphysician must have observed, not only that no thought is alone, but that thoughts commonly go in pairs; though the related thoughts first appeared in his mind at long distances of time. Things are in pairs: a natural fact has only half its value, until a fact in moral nature, its counterpart, is stated. Then they confirm and adorn each other; a story is matched by another story. And that may be the reason why, when a gentleman has told a good thing, he immediately tells it again.

Nothing seems so cheap as the benefit of conversation: nothing is more rare. ’Tis wonderful how you are balked and baffled. There is plenty of intelligence, reading, curiosity; but serious, happy discourse, avoiding personalities, dealing with results, is rare: and I seldom meet with a reading and thoughtful person but he tells me, as if it were his exceptional mishap, that he has no companion.

Suppose such a one to go out exploring different circles in search of this wise and genial counterpart,—he might inquire far and wide. Conversation in society is found to be on a platform so low as to exclude science, the saint, and the poet. Amidst all the gay banter, sentiment cannot profane itself and venture out. The reply of old Isocrates comes so often to mind,—“The things which are now seasonable I cannot say; and for the things which I can say it is not now the time.� Besides, who can resist the charm of talent? The lover of letters loves power too. Among the men of wit and learning, he could not withhold his homage from the gayety, grasp of memory, luck, splendor, and speed; such exploits of discourse, such feats of society! What new powers, what mines of wealth! But when he came home, his brave sequins were dry leaves. He found either that the fact they had thus dizened and adorned was of no value, or that he already knew all and more than all they had told him. He could not find that he was helped by so much as one thought or principle, one solid fact, one commanding impulse: great was the dazzle, but the gain was small. He uses his occasions; he seeks the company of those who have convivial talent. But the moment they meet, to be sure they begin to be something else than they were; they play pranks, dance jigs, run on each other, pun, tell stories, try many fantastic tricks, under some superstition that there must be excitement and elevation;—and they kill conversation at once. I know well the rusticity of the shy hermit. No doubt he does not make allowance enough for men of more active blood and habit. But it is only on natural ground that conversation can be rich. It must not begin with uproar and violence. Let it keep the ground, let it feel the connection with the battery. Men must not be off their centres.
