Custom and Habit.

INquiring into the nature of man as a sensitive being, and finding him affected in a high degree with novelty, would any one conjecture that he is equally affected with custom? Yet these frequently take place, not only in the same person, but even with relation to the same subject: when new, it is inchanting; familiarity renders it indifferent; and custom, after a longer familiarity, makes it again desirable. Human nature, diversified with many and various springs of action, is wonderfully, and, indulging the expression, intricately constructed.

Custom hath such influence upon many of our feelings, by warping and varying them, that we must attend to its operations if we would be acquainted with human nature. This subject, in itself obscure, has been much neglected; and to give a complete analysis of it will be no easy task. I pretend only to touch it cursorily; hoping, however, that what is here laid down, will dispose more diligent inquirers to attempt further discoveries.

Custom respects the action, habit the actor. By custom we mean, a frequent reiteration of the same act; and by habit, the effect that custom has on the mind or body. This effect may be either active, witness the dexterity produced by custom in performing certain exercises; or passive, as when, by custom, a peculiar connection is formed betwixt a man and some agreeable object, which acquires thereby a greater power to raise emotions in him than it hath naturally. Active habits come not under the present undertaking; and therefore I confine myself to those that are passive.

This subject is thorny and intricate. Some pleasures are fortified by custom; and yet custom begets familiarity, and consequently indifference[24]. In many instances, satiety and disgust are the consequences of reiteration. Again, though custom blunts the edge of distress and of pain; yet the want of any thing to which we have long been accustomed, is a sort of torture. A clue to guide us through all the intricacies of this labyrinth, would be an acceptable present.

Whatever be the cause, it is an established fact, that we are much influenced by custom. It hath an effect upon our pleasures, upon our actions, and even upon our thoughts and sentiments. Habit makes no figure during the vivacity of youth; in middle age it gains ground; and in old age it governs without control. In that period of life, generally speaking, we eat at a certain hour, take exercise at a certain hour, go to rest at a certain hour, all by the direction of habit. Nay a particular seat, table, bed, comes to be essential. And a habit in any of these, cannot be contradicted without uneasiness.

Any slight or moderate pleasure frequently reiterated for a long time, forms a connection betwixt us and the thing that causes the pleasure. This connection, termed habit, has the effect to raise our desire or appetite for that thing when it returns not as usual. During the course of enjoyment, the pleasure grows insensibly stronger till a habit be established; at which time the pleasure is at its height. It continues not however stationary. The same customary reiteration which carried it to its height, brings it down again by insensible degrees, even lower than it was at first. But of this circumstance afterward. What at present we have in view, is to prove by experiments, that those things which at first are but moderately agreeable, are the aptest to become habitual. Spirituous liquors, at first scarce agreeable, readily produce an habitual appetite; and custom prevails so far, as even to make us fond of things originally disagreeable, such as coffee, assa-soetida, and tobacco. This is pleasantly illustrated by Congreve:

A walk upon the quarterdeck, though intolerably confined, becomes however so agreeable by custom, that a sailor in his walk on shore, confines himself commonly within the same bounds. I knew a man who had relinquished the sea for a country-life. In the corner of his garden he reared an artificial mount with a level summit, resembling most accurately a quarterdeck, not only in shape but in size; and this was his choice walk. Play or gaming, at first barely amusing by the occupation it affords, becomes in time extremely agreeable; and is frequently prosecuted with avidity, as if it were the chief business of life. The same observation is applicable to the pleasures of the internal senses, those of knowledge and virtue in particular. Children have scarce any sense of these pleasures; and men very little, who are in the state of nature without culture. Our taste for virtue and knowledge improves slowly; but is capable of growing stronger than any other appetite in human nature.

To introduce a habit, frequency of acts is not alone sufficient: length of time is also necessary. The quickest succession of acts in a short time, is not sufficient; nor a slow succession in the longest time. The effect must be produced by a moderate soft action, and a long series of easy touches removed from each other by short intervals. Nor are these sufficient, without regularity in the time, place, and other circumstances of the action. The more uniform any operation is, the sooner it becomes habitual; and this holds equally in a passive habit. Variety in any remarkable degree, prevents the effect. Thus any particular food will scarce ever become habitual, where the manner of dressing is varied. The circumstances then requisite to augment any pleasure and at the long run to form a habit, are weak uniform acts, reiterated during a long course of time without any considerable interruption. Every agreeable cause which operates in this manner, will grow habitual.

Affection and aversion, as distinguished from passion on the one hand, and on the other from original disposition, are in reality habits respecting particular objects, acquired in the manner above set forth. The pleasure of social intercourse with any person, must originally be faint, and frequently reiterated, in order to establish the habit of affection. Affection thus generated, whether it be friendship or love, seldom swells into any tumultuous or vigorous passion; but is however the strongest cement that can bind together two individuals of the human species. In like manner, a slight degree of disgust often reiterated with any degree of regularity, grows into the habit of aversion, which generally subsists for life.

Those objects of taste that are the most agreeable, are so far from having a tendency to become habitual, that too great indulgence fails not to produce satiety and disgust. No man contracts a habit of taking sugar, honey, or sweet-meats, as he doth of tobacco:

The same holds in the causes of all violent pleasures: these causes are not naturally susceptible of habit. Great passions suddenly raised are incompatible with a habit of any sort. In particular they never produce affection or aversion. A man who at first sight falls violently in love, has a strong desire of enjoyment, but no affection for the woman[25]. A man who is surprised with an unexpected savour, burns for an opportunity to exert his gratitude, without having any affection for his benefactor. Neither does desire of vengeance for an atrocious injury involve aversion.

It is perhaps not easy to say why moderate pleasures gather strength by custom. But two causes concur to prevent this effect in the more intense pleasures. These, by an original law in our nature, increase quickly to their full growth, and decay with no less precipitation[26]; and custom is too slow in its operation to overcome this law. Another cause is not less powerful. The mind is exhausted with pleasure as well as with pain. Exquisite pleasure is extremely fatiguing; occasioning, as a naturalist would say, great expence of animal spirits[27]. And therefore, of such the mind cannot bear so frequent gratification as to superinduce a habit. If the thing which raises the pleasure return before the mind have recovered its tone and relish, disgust ensues instead of pleasure.

A habit never fails to admonish us of the wonted time of gratification, by raising a pain for want of the object, and a desire to have it. The pain of want is always first felt; the desire naturally follows; and upon presenting the object, both vanish instantaneously. Thus a man accustomed to tobacco, feels, at the end of the usual interval, a confused pain of want, which in its first appearance points at nothing in particular, though it soon settles upon its accustomed object. The same may be observed in persons addicted to drinking, who are often in an uneasy restless state before they think of their bottle. In pleasures indulged regularly and at equal intervals, the appetite, remarkably obsequious to custom, returns regularly with the usual time of gratification; and a sight of the object in the interim, has scarce any power to move it. This pain of want arising from habit, seems directly opposite to that of satiety. Singular it must appear, that frequency of gratification should produce effects so opposite as are the pains of excess and of want.

The appetites that respect the preservation and propagation of our species, are attended with a pain of want similar to that occasioned by habit. Hunger and thirst are uneasy sensations of want, which always precede the desire of eating or drinking: and a pain for want of carnal enjoyment precedes the desire of a proper object. The pain being thus felt independent of an object, cannot be cured but by gratification. An ordinary passion, in which desire precedes the pain of want, is in a different condition. It is never felt but while the object is in view; and therefore by removing the object out of thought, it vanisheth with its desire and pain of want[28].

These natural appetites above mentioned, differ from habit in the following particular, They have an undetermined direction toward all objects of gratification in general; whereas an habitual appetite is directed upon a particular object. The attachment we have by habit to a particular woman, differs widely from the natural passion which comprehends the whole sex; and the habitual relish for a particular dish, is far from being the same with a vague appetite for food. Notwithstanding this difference, it is still remarkable, that nature hath inforced the gratification of certain natural appetites essential to the species, by a pain of the same sort with that which habit produceth.

The pain of habit is less under our power, than any other pain for want of gratification. Hunger and thirst are more easily endured, especially at first, than an unusual intermission of any habitual pleasure. We often hear persons declaring, they would forego sleep or food, rather than snuff or any other habitual trifle. We must not however conclude, that the gratification of an habitual appetite affords the same delight with the gratification of one that is natural. Far from it: the pain of want only is greater.

The slow and reiterated acts that produce a habit, strengthen the mind to enjoy the habitual pleasure in greater quantity and more frequency than originally; and by this means a habit of intemperate gratification is often formed. After unbounded acts of intemperance, the habitual relish is soon restored, and the pain for want of enjoyment returns with fresh vigor.

The causes of the pleasant emotions hitherto in view, are either an individual, such as a companion, a certain dwelling-place, certain amusements, &c.; or a particular species, such as coffee, mutton, or any particular food. But habit is not confined to these. A constant train of trifling diversions, may form such a habit in the mind, as that it cannot be easy a moment without amusement. Variety in the objects prevents a habit as to any one in particular; but as the train is uniform with respect to amusement in general, the habit is formed accordingly; and this sort of habit may be denominated a generic habit, in opposition to the former, which may be called a specific habit. A habit of a town-life, of country-sports, of solitude, of reading, or of business, where sufficiently varied, are instances of generic habits. It ought to be remarked, that every specific habit hath a mixture of the generic. The habit of one particular sort of food, makes the taste agreeable; and we are fond of this taste where-ever found. A man deprived of an habitual object, takes up with what most resembles it: deprived of tobacco, any bitter herb will do, rather than want. The habit of drinking punch, makes wine a good resource. A man accustomed to the sweet society and comforts of matrimony, being unhappily deprived of his beloved object, inclines the sooner to a second choice. In general, the quality which the most affects us in an habitual object, produceth, when we are deprived of it, a strong appetite for that quality in any other object.

The reasons are assigned above, why the causes of intense pleasure become not readily habitual. But now I must observe, that these reasons conclude only against specific habits. With regard to any particular object that is the cause of a weak pleasure, a habit is formed by frequency and uniformity of reiteration, which in the case of an intense pleasure cannot obtain without satiety and disgust. But it is remarkable, that satiety and disgust have no effect, except as to that thing which occasions them. A surfeit of honey produceth not a loathing of sugar; and intemperance with one woman, produceth no disrelish of the same pleasure with others. Hence it is easy to account for a generic habit in any strong pleasure. The disgust of intemperance, is confined to the object by which it is produced. The delight we had in the gratification of the appetite, inflames the imagination, and makes us, with avidity, search for the same gratification in whatever other object it can be found. And thus frequency and uniformity in gratifying the same passion upon different objects, produceth at the longrun a habit. In this manner, a man acquires an habitual delight in high and poignant sauces, rich dress, fine equipage, crowds of company, and in whatever is commonly termed pleasure. There concurs at the same time to introduce this habit, a peculiarity observed above, that reiteration of acts enlarges the capacity of the mind, to admit a more plentiful gratification than originally, with regard to frequency as well as quantity.

Hence it appears, that though a specific habit can only take place in the case of a moderate pleasure, yet that a generic habit may be formed with respect to every sort of pleasure, moderate or immoderate, that can be gratified by a variety of objects indifferently. The only difference is, that any particular object which causes a weak pleasure, runs naturally into a specific habit; whereas a particular object that causes an intense pleasure, is altogether incapable of such a habit. In a word, it is but in singular cases that a moderate pleasure produces a generic habit: an intense pleasure, on the other hand, cannot produce any other habit.

The appetites that respect the preservation and propagation of the species, are formed into habit in a peculiar manner. The time as well as measure of their gratification, are much under the power of custom; which, by introducing a change upon the body, occasions a proportional change in the appetites. Thus, if the body be gradually formed to a certain quantity of food at regular times, the appetite is regulated accordingly; and the appetite is again changed when a different habit of body is introduced by a different practice. Here it would seem, that the change is not made upon the mind, which is commonly the case in passive habits, but only upon the body.

When rich food is brought down by ingredients of a plainer taste, the composition is susceptible of a specific habit. Thus the sweet taste of sugar, rendered less poignant in a mixture, may, in course of time, produce a specific habit for such mixture. As moderate pleasures, by becoming more intense, tend to generic habits; so intense pleasures, by becoming more moderate, tend to specific habits.

The beauty of the human figure, by a special recommendation of nature, appears to us supreme, amid the great variety of beauteous forms bestowed upon animals. The various degrees in which individuals enjoy this property, render it an object sometimes of a moderate sometimes of an intense passion. The moderate passion, admitting frequent reiteration without diminution, and occupying the mind without exhausting it, becomes gradually stronger till it settle in a habit. So true this is, that instances are not wanting, of an ugly face, at first disagreeable, afterward rendered indifferent by familiarity, and at the longrun agreeable. On the other hand, consummate beauty, at the very first view, fills the mind so as to admit no increase. Enjoyment in this case lessens the pleasure[29]; and if often repeated, ends commonly in satiety and disgust. Constant experience shows, that the emotions created by great beauty become weaker by familiarity. The impressions made successively by such an object, strong at first and lessening by degrees, constitute a series opposite to that of the weak and increasing emotions, which grow into a specific habit. But the mind, when accustomed to beauty, contracts a relish for it in general, though often repelled from particular objects by the pain of satiety. Thus a generic habit is formed, of which inconstancy in love is the necessary consequence. For a generic habit, comprehending every beautiful object, is an invincible obstruction to a specific habit, which is confined to one.

But a matter which is of great importance to the youth of both sexes, deserves more than a cursory view. Though the pleasant emotion of beauty differs widely from the corporeal appetite, yet both may concur upon the same object. When this is the case, they inflame the imagination; and produce a very strong complex passion[30], which is incapable of increase, because the mind as to pleasure is limited rather more than as to pain. Enjoyment in this case must be exquisite, and therefore more apt to produce satiety than in any other case whatever. This is a never-failing effect, where consummate beauty on the one side, meets with a warm imagination and great sensibility on the other. What I am here explaining, is the naked truth without exaggeration. They must be insensible upon whom this doctrine makes no impression; and it deserves well to be pondered by the young and the amorous, who in forming a society which is not dissolvable, are too often blindly impelled by the animal pleasure merely, inflamed by beauty. It may indeed happen after this pleasure is gone, and go it must with a swift pace, that a new connection is formed upon more dignified and more lasting principles. But this is a dangerous experiment. For even supposing good sense, good temper, and internal merit of every sort, which is a very favourable supposition, yet a new connection upon these qualifications is rarely formed. It generally or rather always happens, that such qualifications, the only solid foundation of an indissoluble connection, are rendered altogether invisible by satiety of enjoyment creating disgust.

One effect of custom, different from any that have been explained, must not be omitted, because it makes a great figure in human nature. Custom augments moderate pleasures, and diminishes those that are intense. It has a different effect with respect to pain; for it blunts the edge of every sort of pain and distress great and small. Uninterrupted misery therefore is attended with one good effect. If its torments be incessant, custom hardens us to bear them.

It is extremely curious, to remark the gradual changes that are made in forming habits. Moderate pleasures are augmented gradually by reiteration till they become habitual; and then are at their height. But they are not long stationary; for from that point they gradually decay till they vanish altogether. The pain occasioned by the want of gratification, runs a very different course. This pain increases uniformly; and at last becomes extreme, when the pleasure of gratification is reduced to nothing.

The effect of custom with relation to a specific habit, is displayed through all its varieties in the use of tobacco. The taste of this plant is at first extremely unpleasant. Our disgust lessens gradually till it vanish altogether; at which period the plant is neither agreeable nor disagreeable. Continuing the use, we begin to relish it; and our relish increases by use till it come to its utmost extent. From this state it gradually decays, while the habit becomes stronger and stronger, and consequently the pain of want. The result is, that when the habit has acquired its greatest vigor, the pleasure of gratification is gone. And hence it is, that we often smoke and take snuff habitually, without so much as being conscious of the operation. We must except gratification after the pain of want; because gratification in that case is at the height when the habit is strongest. It is of the same kind with the joy one feels upon being delivered from the rack, the cause of which is explained above[31]. This pleasure however is but occasionally the effect of habit; and however exquisite, is guarded against as much as possible, by preventing want.

With regard to the pain of want, I can discover no difference betwixt a generic and specific habit: the pain is the same in both. But these habits differ widely with respect to the positive pleasure. I have had occasion to observe, that the pleasure of a specific habit decays gradually till it become imperceptible. Not so the pleasure of a generic habit. So far as I can discover, this pleasure suffers little or no decay after it comes to its height. The variety of gratification preserves it entire. However it may be with other generic habits, the observation I am certain holds with respect to the pleasures of virtue and of knowledge. The pleasure of doing good has such an unbounded scope, and may be so variously gratified, that it can never decay. Science is equally unbounded; and our appetite for knowledge has an ample range of gratification, where discoveries are recommended by novelty, by variety, by utility, or by all of them.

Here is a large field of facts and experiments, and several phenomena unfolded, the causes of which have been occasionally suggested. The efficient cause of the power of custom over man, a fundamental point in the present chapter, has unhappily evaded my keenest search; and now I am reduced to hold it an original branch of the human constitution, though I have no better reason for my opinion, than that I cannot resolve it into any other principle. But with respect to the final cause, a point of still greater importance, I promise myself more success. It cannot indeed have escaped any thinking person, that the power of custom is a happy contrivance for our good. Exquisite pleasure produceth satiety: moderate pleasure becomes stronger by custom. Business is our province, and pleasure our relaxation only. Hence, satiety is necessary to check exquisite pleasures, which otherwise would ingross the mind, and unqualify us for business. On the other hand, habitual increase of moderate pleasure, and even conversion of pain into pleasure, are admirably contrived for disappointing the malice of Fortune, and for reconciling us to whatever course of life may be our lot:

The foregoing distinction betwixt intense and moderate, holds in pleasure only, not in pain, every degree of which is softened by time and custom. Custom is a catholicon for pain and distress of every sort; and of this regulation the final cause is so evident as to require no illustration.

Another final cause of custom will be highly relished by every person of humanity; and yet has in a great measure been overlooked. Custom hath a greater influence than any other known principle, to put the rich and poor upon a level. Weak pleasures, which fall to the share of the latter, become fortunately stronger by custom; while voluptuous pleasures, the lot of the former, are continually losing ground by satiety. Men of fortune, who possess palaces, sumptuous gardens, rich fields, enjoy them less than passengers do. The goods of Fortune are not unequally distributed: the opulent possess what others enjoy.

And indeed, if it be the effect of habit to produce the pain of want in a high degree while there is little pleasure in enjoyment, a voluptuous life is of all the least to be envied. Those who are accustomed to high feeding, easy vehicles, rich furniture, a crowd of valets, much deference and flattery, enjoy but a small share of happiness, while they are exposed to manifold distresses. To such a man, inslaved by ease and luxury, even the petty inconveniencies of a rough road, bad weather, or homely fare on a journey, are serious evils. He loses his tone of mind, becomes peevish, and would wreak his resentment even upon the common accidents of life. Better far to use the goods of Fortune with moderation. A man who by temperance and activity has acquired a hardy constitution, is, on the one hand, guarded against external accidents, and is, on the other, provided with great variety of enjoyment ever at command.

I shall close this chapter with the discussion of a question more delicate than abstruse, viz. What authority custom ought to have over our taste in the fine arts? It is proper to be premised, that we chearfully abandon to its authority every thing that nature leaves to our choice, and where the preference we bestow has no foundation other than whim or fancy. There appears no original difference betwixt the right and the left hand: custom however has established a difference, so as to make it aukward and disagreeable to use the left where the right is commonly used. The various colours, though they affect us differently, are all of them agreeable in their purity. But custom has regulated this matter in another manner: a black skin upon a human creature, is to us disagreeable; and a white skin probably not less so to a negro. Thus things originally indifferent, become agreeable or disagreeable by the force of custom. Nor ought this to be surprising after the discovery made above, that the original agreeableness or disagreeableness of an object, is, by the influence of custom, often converted into the opposite quality.

Concerning now those matters of taste where there is naturally a preference of one thing before another; it is certain, in the first place, that our faint and more delicate feelings are readily susceptible of a bias from custom; and therefore that it is no proof of a defective taste, to find these in some measure under the government of custom. Dress, and the modes of external behaviour, are justly regulated by custom in every country. The deep red or vermilion with which the ladies in France cover their cheeks, appears to them beautiful in spite of nature; and strangers cannot altogether be justified in condemning this practice, considering the lawful authority of custom, or of the fashion, as it is called. It is told of the people who inhabit the skirts of the Alps facing the north, that the swelling they universally have in the neck is to them agreeable. So far has custom power to change the nature of things, and to make an object originally disagreeable take on an opposite appearance.

But as to the emotions of propriety and impropriety, and in general as to all emotions involving the sense of right or wrong, custom has little authority, and ought to have none at all. Emotions of this kind, being qualified with the consciousness of duty, take naturally place of every other feeling; and it argues a shameful weakness or degeneracy of mind, to find them in any case so far subdued as to submit to custom.

These few hints may enable us to judge in some measure of foreign manners, whether exhibited by foreign writers or our own. A comparison betwixt the ancients and the moderns, was some time ago a favourite subject. Those who declared for the former, thought it a sufficient justification of ancient manners, that they were supported by the authority of custom. Their antagonists, on the other hand, refusing submission to custom as a standard of taste, condemned ancient manners in several instances as irrational. In this controversy, an appeal being made to different principles, without the slightest attempt on either side to establish a common standard, the dispute could have no end. The hints above given tend to establish a standard, for judging how far the lawful authority of custom may be extended, and within what limits it ought to be confined. For the sake of illustration, we shall apply this standard in a few instances.

Human sacrifices, the cruellest effect of blind and groveling superstition, wore gradually out of use by the prevalence of reason and humanity. In the days of Sophocles and Euripides, the traces of this savage practice were still recent; and the Athenians, through the prevalence of custom, could without disgust suffer human sacrifices to be represented in their theatre. The Iphigenia of Euripides is a proof of this fact. But a human sacrifice, being altogether inconsistent with modern manners, as producing horror instead of pity, cannot with any propriety be introduced upon a modern stage. I must therefore condemn the Iphigenia of Racine, which, instead of the tender and sympathetic passions, substitutes disgust and horror. But this is not all. Another objection occurs against every fable that deviates so remarkably from improved notions and sentiments. If it should even command our belief, by the authority of genuine history, its fictitious and unnatural appearance, however, would prevent its taking such hold of the mind as to produce a perception of reality[32]. A human sacrifice is so unnatural, and to us so improbable, that few will be affected with the representation of it more than with a fairy tale. The objection first mentioned strikes also against the Phedra of this author. The queen’s passion for her stepson, being unnatural and beyond all bounds, creates aversion and horror rather than compassion. The author in his preface observes, that the queen’s passion, however unnatural, was the effect of destiny and the wrath of the gods; and he puts the same excuse in her own mouth. But what is the wrath of a heathen god to us Christians? We acknowledge no destiny in passion; and if love be unnatural, it never can be relished. A supposition, like what our author lays hold of, may possibly cover slight improprieties; but it will never engage our sympathy for what appears to us frantic or extravagant.

Neither can I relish the catastrophe of this tragedy. A man of taste may peruse, without disgust, a Grecian performance describing a sea-monster sent by Neptune to destroy Hippolytus. He considers, that such a story might agree with the religious creed of Greece; and, entering into ancient opinions, may be pleased with the story, as what probably had a strong effect upon a Grecian audience. But he cannot have the same indulgence for such a representation upon a modern stage; for no story which carries a violent air of fiction, can ever move us in any considerable degree.

In the CoËphores of Eschylus[33], Orestes is made to say, that he was commanded by Apollo to avenge his father’s murder; and yet if he obeyed, that he was to be delivered to the furies, or be struck with some horrible malady. The tragedy accordingly concludes with a chorus, deploring the fate of Orestes, obliged to take vengeance against a mother, and involved thereby in a crime against his will. It is impossible for any man at present to accommodate his mind to opinions so irrational and absurd, which must disgust him in perusing even a Grecian story. Among the Greeks again, grossly superstitious, it was a common opinion, that the report of a man’s death was a presage of his death; and Orestes, in the first act of Electra, spreading a report of his own death in order to blind his mother and her adulterer, is even in this case affected with the presage. Such imbecility can never find grace with a modern audience. It may indeed produce some degree of compassion for a people afflicted to such a degree with absurd terrors, similar to what is felt in perusing a description of the Hottentotes: but manners of this kind will not interest our affections, nor excite any degree of social concern.
