Adapted from An Enquiry Concerning Human Understanding by David Hume (1748)

Everyone will readily allow that there is a considerable difference between the perceptions of the mind, when a man feels the pain of excessive heat, or the pleasure of moderate warmth, and when he afterwards recalls to his memory this sensation, or anticipates it by his imagination. These faculties may mimic or copy the perceptions of the senses, but they never can entirely reach the force and vivacity of the original sentiment. The utmost we say of them, even when they operate with greatest vigor, is, that they represent their object in so lively a manner that we could almost say we feel or see it. But, except the mind be disordered by disease or madness, they never can arrive at such a pitch of vivacity as to render these perceptions altogether undistinguishable. All the colors of poetry, however splendid, can never paint natural objects in such a manner as to make the description be taken for a real landscape. The most lively thought is still inferior to the dullest sensation.

We may observe a like distinction to run through all the other perceptions of the mind. A man in a fit of anger is actuated in a very different manner from one who only thinks of that emotion. If you tell me that any person is in love I easily understand your meaning, and form a just conception of his situation, but never can mistake that conception for the real disorders and agitations of the passion. When we reflect on our past sentiments and affections, our thought is a faithful mirror and copies its objects truly, but the colors which it employs are faint and dull in comparison of those in which our original perceptions were clothed. It requires no nice discernment or metaphysical head to mark the distinction between them.

Here, therefore, we may divide all the perceptions of the mind into two classes or species, which are distinguished by their different degrees of force and vivacity. The less forcible and lively are commonly denominated "thoughts" or "ideas." The other species want a name in our language, and in most others; I suppose because it was not requisite for any but philosophical purposes to rank them under a general term or appellation. Let us, therefore, use a little freedom, and call them "impressions," employing that word in a sense somewhat different from the usual. By the term "impression," then, I mean all our more lively perceptions, when we hear, or see, or feel, or love, or hate, or desire, or will. And impressions are distinguished from ideas, which are the less lively perceptions, of which we are conscious when we reflect on any of those sensations or movements above mentioned.

Adapted from "The Eulogy of the Dog" by George Graham Vest (1870)

The best friend a man has in this world may turn against him and become his enemy. His son or daughter whom he has reared with loving care may prove ungrateful. Those who are nearest and dearest to us, those whom we trust with our happiness and our good name, may become traitors to their faith. The money that a man has, he may lose. It flies away from him, perhaps when he needs it the most. A man’s reputation may be sacrificed in a moment of ill-considered action. The people who are prone to fall on their knees to do us honor when success is with us may be the first to throw the stone of malice when failure settles its cloud upon our heads. The one absolutely unselfish friend that a man can have in this selfish world, the one that never deserts him and the one that never proves ungrateful or treacherous is his dog.

Gentlemen of the jury, a man’s dog stands by him in prosperity and in poverty, in health and in sickness. He will sleep on the cold ground, where the wintry winds blow and the snow drives fiercely, if only he can be near his master’s side. He will kiss the hand that has no food to offer, he will lick the wounds and sores that come in encounter with the roughness of the world. He guards the sleep of his pauper master as if he were a prince.

When all other friends desert, he remains. When riches take wings and reputation falls to pieces, he is as constant in his love as the sun in its journey through the heavens. If fortune drives the master forth an outcast into the world, friendless and homeless, the faithful dog asks no higher privilege than that of accompanying him, to guard him against danger, to fight against his enemies. And when the last scene of all comes, and death takes his master in its embrace and his body is laid in the cold ground, no matter if all other friends pursue their way, there by his graveside will the noble dog be found, his head between his paws, his eyes sad but open, in alert watchfulness, faithful and true, even unto death.

Adapted from "Nature" by Ralph Waldo Emerson (1836)

To go into solitude, a man needs to retire as much from his chamber as from society. I am not solitary whilst I read and write, though nobody is with me. But if a man would be alone, let him look at the stars. The rays that come from those heavenly worlds will separate between him and what he touches. One might think the atmosphere was made transparent with this design, to give man, in the heavenly bodies, the perpetual presence of the sublime. Seen in the streets of cities, how great they are! If the stars should appear one night in a thousand years, how would men believe and adore, and preserve for many generations the remembrance of the city of God which had been shown! But every night come out these envoys of beauty, and light the universe with their admonishing smile.

The stars awaken a certain reverence, because though always present, they are inaccessible; but all natural objects make a kindred impression, when the mind is open to their influence. Nature never wears a mean appearance. Neither does the wisest man extort her secret, and lose his curiosity by finding out all her perfection. Nature never became a toy to a wise spirit. The flowers, the animals, the mountains, reflected the wisdom of his best hour, as much as they had delighted the simplicity of his childhood.

When we speak of nature in this manner, we have a distinct but most poetical sense in the mind. We mean the integrity of impression made by manifold natural objects. It is this which distinguishes the stick of timber of the wood-cutter, from the tree of the poet. The charming landscape which I saw this morning, is indubitably made up of some twenty or thirty farms. Miller owns this field, Locke that, and Manning the woodland beyond. But none of them owns the landscape. There is a property in the horizon which no man has but he whose eye can integrate all the parts, that is, the poet. This is the best part of these men's farms, yet to this their warranty-deeds give no title.

To speak truly, few adult persons can see nature. Most persons do not see the sun. At least they have a very superficial seeing. The sun illuminates only the eye of the man, but shines into the eye and the heart of the child. The lover of nature is he whose inward and outward senses are still truly adjusted to each other; who has retained the spirit of infancy even into the era of manhood. His intercourse with heaven and earth becomes part of his daily food. In the presence of nature, a wild delight runs through the man, in spite of real sorrows. Nature says,—he is my creature, and maugre all his impertinent grief’s, he shall be glad with me. Not the sun or the summer alone, but every hour and season yields its tribute of delight; for every hour and change corresponds to and authorizes a different state of the mind, from breathless noon to grimmest midnight. Nature is a setting that fits equally well a comic or a mourning piece. In good health, the air is a cordial of incredible virtue. Crossing a bare common, in snow puddles, at twilight, under a clouded sky, without having in my thoughts any occurrence of special good fortune, I have enjoyed a perfect exhilaration. I am glad to the brink of fear. In the woods too, a man casts off his years, as the snake his slough, and at whatever period of life, is always a child. In the woods, is perpetual youth. Within these plantations of God, a decorum and sanctity reign, a perennial festival is dressed, and the guest sees not how he should tire of them in a thousand years. In the woods, we return to reason and faith. There I feel that nothing can befall me in life,—no disgrace, no calamity, (leaving me my eyes,) which nature cannot repair. Standing on the bare ground,—my head bathed by the blithe air, and uplifted into infinite space,—all mean egotism vanishes. I become a transparent eye-ball; I am nothing; I see all; the currents of the Universal Being circulate through me; I am part or particle of God. The name of the nearest friend sounds then foreign and accidental: to be brothers, to be acquaintances,—master or servant, is then a trifle and a disturbance. I am the lover of uncontained and immortal beauty. In the wilderness, I find something more dear and connate than in streets or villages. In the tranquil landscape, and especially in the distant line of the horizon, man beholds somewhat as beautiful as his own nature.

Adapted from “Two Ways of Seeing a River” in Life on the Mississippi by Mark Twain (1883)

Now when I had mastered the language of this water and had come to know every trifling feature that bordered the great river as familiarly as I knew the letters of the alphabet, I had made a valuable acquisition. But I had lost something, too. I had lost something which could never be restored to me while I lived. All the grace, the beauty, the poetry had gone out of the majestic river! I still keep in mind a certain wonderful sunset which I witnessed when steam boating was new to me. A broad expanse of the river was turned to blood; in the middle distance the red hue brightened into gold, through which a solitary log came floating, black and conspicuous; the shore on our left was densely wooded, and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun. There were graceful curves, reflected images, woody heights, soft distances; and over the whole scene, far and near, the dissolving lights drifted steadily, enriching it, every passing moment, with new marvels of coloring.

I stood like one bewitched. I drank it in, in a speechless rapture. The world was new to me, and I had never seen anything like this at home. But as I have said, a day came when I began to cease from noting the glories and the charms which the moon and the sun and the twilight wrought upon the river's face; another day came when I ceased altogether to note them. Then, if that sunset scene had been repeated, I should have looked upon it without rapture, and should have commented upon it, inwardly, in this fashion: "This sun means that we are going to have wind tomorrow; that floating log means that the river is rising, small thanks to it; that slanting mark on the water refers to a bluff reef which is going to kill somebody's steamboat one of these nights, if it keeps on stretching out like that; that silver streak in the shadow of the forest is the 'break' from a new snag, and he has located himself in the very best place he could have found to fish for steamboats; that tall dead tree, with a single living branch, is not going to last long, and then how is a body ever going to get through this blind place at night without the friendly old landmark?"

No, the romance and the beauty were all gone from the river. All the value any feature of it had for me now was the amount of usefulness it could furnish toward compassing the safe piloting of a steamboat. Since those days, I have pitied doctors from my heart. What does the lovely flush in a beauty's cheek mean to a doctor but a "break" that ripples above some deadly disease? Are not all her visible charms sown thick with what are to him the signs and symbols of hidden decay? Does he ever see her beauty at all, or doesn't he simply view her professionally, and comment upon her unwholesome condition all to himself? And doesn't he sometimes wonder whether he has gained most or lost most by learning his trade?

Adapted from a letter of Thomas Jefferson popularly known as “A Dialogue Between the Head and Heart” (October 12th, 1786) in Volume II of Memoir, Correspondence, and Miscellanies, from the Papers of Thomas Jefferson (1830)

(Note: This work is presented like a play having two characters, the “Head” and the “Heart.” In the following passage, we are privy to the words of the “Head.”)

Every thing in this world is matter of calculation. Advance, then, with caution, the balance in your hand. Put into one scale the pleasures which any object may offer, but put fairly into the other the pains which are to follow, and see which preponderates. The making an acquaintance is not a matter of indifference. When a new one is proposed to you, view it all round. Consider what advantages it presents, and to what inconveniences it may expose you. Do not bite at the bait of pleasure, till you know there is no hook beneath it. The art of life is the art of avoiding pain, and he is the best pilot, who steers clearest of the rocks and shoals with which it is beset. Pleasure is always before us, but misfortune is at our side; while running after that, this arrests us.

The most effectual means of being secure against pain is to retire within ourselves and to suffice for our own happiness. Those which depend on ourselves are the only pleasures a wise man will count on, for nothing is ours, which another may deprive us of. Hence the inestimable value of intellectual pleasures. Ever in our power, always leading us to something new, never cloying, we ride serene and sublime above the concerns of this mortal world, contemplating truth and nature, matter and motion, the laws which bind up their existence, the laws which bind up their existence, and that Eternal Being, who made and bound them up by those laws.

Let this be our employ. Leave the bustle and tumult of society to those who have not talents to occupy themselves without them. Friendship is but another name for an alliance with the follies and the misfortunes of others. Our own share of miseries is sufficient: why enter then as volunteers into those of another? Is there so little gall poured into our cup, that we must heed help to drink that of our neighbor? A friend dies, or leaves us: we feel as if a limb was cut off. He is sick: we must watch over him, and participate of his pains. His fortune is shipwrecked: ours must be laid under contribution. He loses a child, a parent, or a partner: we must mourn the loss as if it were our own.

Adapted from “Economy” in Walden by Henry David Thoreau (1854)

On the whole, I think that it cannot be maintained that dressing has in this or any country risen to the dignity of an art. At present men make shift to wear what they can get. Like shipwrecked sailors, they put on what they can find on the beach, and at a little distance, whether of space or time, laugh at each other's masquerade. Every generation laughs at the old fashions, but follows religiously the new. We are amused at beholding the costume of Henry VIII, or Queen Elizabeth, as much as if it was that of the King and Queen of the Cannibal Islands. All costume off a man is pitiful or grotesque. It is only the serious eye peering from and the sincere life passed within it which restrain laughter and consecrate the costume of any people. Let Harlequin be taken with a fit of the colic and his trappings will have to serve that mood too. When the soldier is hit by a cannonball, rags are as becoming as purple. 

The childish and savage taste of men and women for new patterns keeps how many shaking and squinting through kaleidoscopes that they may discover the particular figure which this generation requires today. The manufacturers have learned that this taste is merely whimsical. Of two patterns which differ only by a few threads more or less of a particular color, the one will be sold readily, the other lie on the shelf, though it frequently happens that after the lapse of a season the latter becomes the most fashionable. Comparatively, tattooing is not the hideous custom which it is called. It is not barbarous merely because the printing is skin-deep and unalterable.

I cannot believe that our factory system is the best mode by which men may get clothing. The condition of the operatives is becoming every day more like that of the English; and it cannot be wondered at, since, as far as I have heard or observed, the principal object is, not that mankind may be well and honestly clad, but, unquestionably, that corporations may be enriched. In the long run men hit only what they aim at. Therefore, though they should fail immediately, they had better aim at something high.

Adapted from “How I Conquered Stage Fright” by Mark Twain (1906)

My heart goes out in sympathy to anyone who is making his first appearance before an audience of human beings. I recall the occasion of my first appearance. San Francisco knew me then only as a reporter, and I was to make my bow to San Francisco as a lecturer. I knew that nothing short of compulsion would get me to the theater. So I bound myself by a hard-and-fast contract so that I could not escape. I got to the theater forty-five minutes before the hour set for the lecture. My knees were shaking so that I didn't know whether I could stand up. If there is an awful, horrible malady in the world, it is stage-fright--and seasickness. They are a pair. I had stage-fright then for the first and last time. I was only seasick once, too. It was on a little ship on which there were two hundred other passengers. I--was--sick. I was so sick that there wasn't any left for those other two hundred passengers.

It was dark and lonely behind the scenes in that theater, and I peeked through the little peek holes they have in theater curtains and looked into the big auditorium. That was dark and empty, too. By and by it lighted up, and the audience began to arrive. I had got a number of friends of mine, stalwart men, to sprinkle themselves through the audience armed with big clubs. Every time I said anything they could possibly guess I intended to be funny, they were to pound those clubs on the floor. Then there was a kind lady in a box up there, also a good friend of mine, the wife of the governor. She was to watch me intently, and whenever I glanced toward her she was going to deliver a gubernatorial laugh that would lead the whole audience into applause.

At last I began. I had the manuscript tucked under a United States flag in front of me where I could get at it in case of need. But I managed to get started without it. I walked up and down--I was young in those days and needed the exercise--and talked and talked. Right in the middle of the speech I had placed a gem. I had put in a moving, pathetic part which was to get at the hearts and souls of my hearers. When I delivered it they did just what I hoped and expected. They sat silent and awed. I had touched them. Then I happened to glance up at the box where the Governor's wife was--you know what happened.

Well, after the first agonizing five minutes, my stage fright left me, never to return. I know if I was going to be hanged I could get up and make a good showing, and I intend to. But I shall never forget my feelings before the agony left me, and I got up here to thank you for her for helping my daughter, by your kindness, to live through her first appearance. And I want to thank you for your appreciation of her singing, which is, by the way, hereditary.
