When I say that I feel the table, there is a considerable complexity of meaning. Dr. Reid, and his followers, maintain, that I have not one point of33consciousness only, but two; that I feel the sensation, and that I feel the table; that the sensation is one thing, the feeling of the table another. Expositions which will be givenhereafterare necessary to the complete elucidation of what takes place. But the explanations which have been already afforded will enable us to state the facts with considerable clearness. In what is called feeling the table, my organ of touch, and an object of touch, in the appropriate position, are the antecedent; of this antecedent, sensation is the consequent. The expression, “I feel the table,” includes both the antecedent and the consequent. It does not mark the sensation alone; it marks the sensation, and, along with the sensation, its antecedent, namely, the organ, and its object in conjunction.
The phrase, sense of touch, or the word feeling, often synonymous, has the same complexity of meaning, which we have observed in the phrases, sense of hearing, sense of sight, and the rest of the senses.
When I say that I touch, or have the sense of touch, I mean to say, that I have a certain feeling, consequent upon a certain antecedent. The phrase, therefore,notesthe sensation, and at the same timeconnotes4*the following things: 1st, the organ; 2dly,34the object of the organ; 3dly, the synchronous order of the organ and object; 4thly, the successive order of the sensation; the synchronous order being, as usual, the antecedent of the successive order.5*12
4*The use, which I shall make, of the termconnotation, needs to be explained. There is a large class of words, which denote two things, both together; but the one perfectly distinguishable from the other. Of these two things, also, it is observable, that such words express the one,primarily, as it were; the other, in a way which may be calledsecondary. Thus,white, in the phrasewhite horse, denotes two things, the colour, and the horse; but it denotes the colourprimarily, the horsesecondarily. We shall find it very convenient, to say, therefore, that itnotesthe primary,connotesthe secondary, signification.—(Author’s Note.) [Reasons will be assignedfurther on, why the wordsto connoteandconnotationhad better be employed, not as here indicated, but in a different and more special sense.—ED.]

5*The termssynchronousorder, andsuccessiveorder, will be fully explainedhereafter, when any obscurity which may now seem to rest upon them will be removed; it may be useful at present to say, that, by synchronous order, is meant order in space, by successive order, order in time; the first, or order in space, being nothing but the placing or position of the objects at any given time; the second, or order in time, being nothing but the antecedence of the one, and the consequence of the other.—(Author’s Note.)

12Additional Observations on the Sense of Touch.—The author is right in drawing a distinction between Touch proper and the sensibility to Heat and Cold, which, though principally found in the skin, extends beyond the seat of tactile sensibility, as, for example, to the alimentary canal, and to the lungs. It is a debated point, whether the nerves of Touch are also the nerves of Heat and Cold; some persons contending for special nerves of Temperature. Such special nerves, however, have not been proved to exist.The remark is also correct, that the feelings of temperature can be more easily attended to, as simple feelings, than the35feelings of touch proper. The reason is not precisely stated. It is that radiant heat may affect the surface of the body without occasioning resistance or movement, and is thus a purely passive sensibility; a subject-state without an object-accompaniment. When the degree of the sensation varies definitely with definite movements, it is treated as an object sensibility, or as pointing to the object world. Thus when we grow warmer as we move in one direction, and colder as we move in another, we no longer think of the feeling as a purely subject fact, but as having an object, or external embodiment.It is also justly remarked in the text, that the severe sensations of heat, and cold, as well as those from laceration of the skin, may be properly classed with feelings of disorganization generally. At the same time, these painful feelings have a character varying with the organ affected; the fact of injury of tissue may be the same, but the feeling will not be the same, in the skin, the nostrils, the ear, the eye, the alimentary canal.The description above given of the feeling that remains, when the different modifications of resistance are deducted, is scarcely adequate to represent the reality. Frequently it is true of them, that they ‘are mostly moderate, partaking very little of either pain or pleasure,’ but there are occasions when they rise into prominence and power. We may refer to the contact of the bedclothes at night, when the body is relieved from the tight and deadening embrace of the ordinary clothing. The case of greatest moment, however, is the contact of one human being or animal with another; such contact being the physical element in the tender as well as in the sexual affections. There is a combination of tactile sensibility and warmth in this instance, each counting for a part of the pleasure. The influence is well enough known as experienced among human beings; but the sphere of its operation in animals has been but imperfectly explored.If we observe carefully the first movements of a new-born animal, a mammal for example, we find that the guiding and36controlling sensation of its first moments, is the contact with the mother. In that contact, it finds satisfaction and repose; in separation, it is in discomfort and disquiet. Its earliest volitions are to retain and to recover the soft warm touch of the maternal body. When it commences sucking, and has the sensation of nourishment, a new interest springs up, perhaps still more powerful in its attractions, and able to supersede the first, or at least to put it into a second place; yet, during the whole period of maternal dependence, the feeling of touch is a source of powerful sensibility both to the mother and to the offspring. Among animals born in litter, as pigs, kittens, &c., the embrace is equally acceptable between the fellow-progeny themselves. The sensual pleasure of this contact is the essence, the fact, of animal affection, parental and fraternal; and it is the germ, or foundation, and concomitant of tender affection in human beings. It is the experience of this agreeable contact that prepares the way for a still closer conjunction after the animal reaches puberty. Independent of, and antecedent to, that still more acute sensibility, there is a pleasure in the warm embrace of two animals, and they are ready to enter upon it, at all times when the other interests, as nourishment, exercise and repose, are not engrossing. The play of animals with one another clearly involves the pleasure of the embrace, even without sexuality; and it leads to the sexual encounter at the ripe moment.—B.

That we have sensations in parts of the body suffering, or approaching to, disorganization, does not require illustration. The disorganizations of which we speak proceed sometimes from external, sometimes from internal, causes. Lacerations, cuts, bruises, burnings, poisonings, are of the former kind; inflammation, and other diseases in the parts, are the latter.
These sensations are specifically different from those classed under the several heads of sense. The feelings themselves, if attended to, are evidence of this. In the next place, they have neither organ, nor object, in the sense in which those latter feelings have them. We do not talk of an organ of burning; an organ of pain; nor do we talk of an object of any of them; we do not say the object of a cut, the object of an ache, the object of a sore.
Most of those sensations are of the painful kind; though some are otherwise. Some slight, or locally minute inflammations, produce a sensation called itching, which is far from disagreeable, as appears from the desire to scratch, which excites it.13
13The author, in this passage, uses the word itching out of its ordinary sense; making it denote the pleasant sensation accompanying the relief by scratching, instead of the slightly painful, and sometimes highly irritating, sensation which the scratching relieves.—Ed.

38The scratching, which excites the pleasure of itching, is a species of friction, and friction, in most parts of the body, excites a sensation very different from the mere sense of touching or the simple feeling of the object. The tickling of the feather in the nose, for example, is very different from the mere feeling of the feather in touch. In some parts of the body the most intense sensations are produced by friction.
There is difficulty in classing those sensations. They are not the same with those of any of the five senses: and they are not the same with those which rise from any tendency to disorganization in the parts of the body to which they are referred. Great accuracy, however, in the classification of the sensations, is not essential to that acquaintance with them, which is requisite for the subsequent parts of this inquiry. It will suffice for our purpose, if the reader so far attend to them, as to be secure from the danger of overlooking or mistaking them, where a distinct consideration of them is necessary for developing any of the complicated phenomena in which they are concerned.14
14Organic Sensibilities.—The author did well to signalize these sensibilities, so powerful in their influence on human life. They are not confined to the side of pain. The same organs whose disorganization is connected with pain, are, in their healthy and vigorous working, more or less connected with pleasure. This is true not merely of the digestive functions, but of the respiration, the circulation, and others.Nor is it difficult in their case to make up the full analogy39of a sense, as having an Object, an Organ, and a characteristic Sensation. In digestion, the object is the food, the organ is the alimentary canal; in respiration, the object is the air, and the organ the lungs. If it be said that the air is an impalpable agent and not discovered to the mind by its mode of operating, so is heat, the object of an admitted sense.The accurate classification of these feelings may not have much speculative interest, in Psychology, but it has a great practical interest in the diagnosis of disease. For want of subjective knowledge on the part of the patient, and of a well understood nomenclature of subjective symptoms, the discrimination of disease by the feelings is usually very rough.The best mode of arranging these sensibilities seems to be to connect them with their organs, or seats—Muscular Tissue, Bones and Ligaments, Nerves, Heart and Circulation, Lungs, Alimentary Canal. The sensations of itching and tickling are modes of skin sensibility. Tickling is an effect not well understood, although some interesting observations have been made upon it.—B.

There is no part of our Consciousness, which deserves greater attention than this; though, till lately, it has been miserably overlooked. Hartley, Darwin, and Brown, are the only philosophical inquirers into Mind, at least in our own country, who seem to have been aware that it fell within the province of their speculations.
The muscles are bundles of fibres, which, by their contraction and relaxation, produce all the motions of the body. The nerves, with which they are supplied, seem to be the immediate instruments of the muscular action.
That these muscles have the power of acute sensation, we know, by what happens, when they are diseased, when they suffer any external injury, or even when, the integuments being removed, they can be touched, though ever so gently.
It has been said,6*that if we had but one sensation,41and that uninterrupted, it would be as if we had no sensation at all; and, to the justice of this observation, some very striking facts appear to bear evidence. We know that the air is continually pressing upon our bodies. But, the sensation being continual, without any call to attend to it, we lose, from habit, the power of doing so. The sensation is as if it did not exist. We feel the air when it is in motion, or when it is hotter or colder, to a certain degree, than our bodies; but it is because we have the habit of attending to it in those states. As the muscles are always in contact with the same things, the sensations of the muscles must be almost constantly the same. This is one reason why they are very little attended to, and, amid the crowd of other feelings, are, in general, wholly forgotten. They are of that class of feelings which occur as antecedents to other more interesting feelings. To these the attention is immediately called off, and those which preceded and introduced them are forgotten. In such cases the thought of the less interesting sensations is merged in that of the more interesting.

If we had not direct proof, analogy would lead us to conclude, that no change could take place, in parts of so much sensibility as the muscles, without a change of feeling; in particular, that a42distinguishable feeling must attend every contraction, and relaxation. We have proof that there is such a feeling, because intimation is conveyed to the mind that the relaxation or contraction is made. I will, to move my arm; and though I observe the motion by none of my senses, I know that the motion is made. The feeling that attends the motion has existed. Yet so complete is my habit of attending only to the motion, and not to the feeling, that no attention can make me distinctly sensible that I have it. Nay, there are some muscles of the body in constant and vehement action, as the heart, of the feelings attendant upon the action of which we seem to have no cognisance at all. That this is no argument against the existence of those feelings, will be made apparent, by the subsequent explanation of other phenomena, in which the existence of certain feelings, and an acquired incapacity of attending to them, are out of dispute.15
15The paradox, of feelings which we have no cognisance of—feelings which are not felt—will be discussed at large in a futurenote.—Ed.

In most cases of the muscular feelings, there is not only that obscurity, of which we have immediately spoken, but great complexity; as several muscles almost always act together; in many of the common actions of the body, a great number.
The result of these complex feelings is often sufficiently perceptible, though the feelings, separately, can hardly be made objects of attention. The unpleasant feeling of fatigue, in part at least a muscular feeling, is one of those results. The pleasure which almost all the more perfect animals, especially the43young, appear to feel, in even violent exercise, may be regarded as another. The restlessness of a healthy child; the uneasiness in confinement, the delight in the activity of freedom, which so strongly distinguish the vigorous schoolboy; seem to indicate, both a painful state of the muscular system in rest, and a pleasurable state of it in action. Who has not remarked the playful activity of the kitten and the puppy? The delight of the dog, on being permitted to take exercise with his master, extends through the greater part of his life.
One of the cases in which the feeling of muscular action seems the most capable of being attended to, is the pleasure accompanying the act of stretching, which most animals perform in drowsiness, or after sleep.
A very slight degree of reflection is sufficient to evince, that we could not have had the idea of resistance, which forms so great a part of what we call our idea of matter, without the feelings which attend muscular action. Resistance means a force opposed to a force; the force of the object, opposed to the force which we apply to it. The force which we apply is the action of our muscles, which is only known to us by the feelings which accompany it. Our idea of resistance, then, is the idea of our own feelings in applying muscular force. It is true, that the mere feeling of the muscles in action is not the only feeling concerned in the case. The muscles move in consequence of the Will; and what the Will is, we are not as yet prepared to explain. What is necessary at present is, not to shew all the simple feelings which enter into the feeling of resistance; but to shew44that the simple feeling of muscular action is one of them.
The feeling of resistance admits of great varieties. The feeling of a plate of iron is one thing, the feeling of a blown bladder is another, the feeling of quicksilver is a third, the feeling of water a fourth, and so on. The feeling of weight, or attraction, is also a feeling of resistance.

When the sensations in the alimentary canal become acutely painful, they are precise objects of attention to every body.
There is reason to believe that a perpetual train of sensations is going on in every part of it. The food stimulates the stomach. It undergoes important changes, and, mixed with some very stimulating ingredients, passes into the lower intestines; in every part of which it is still farther changed. The degree, and even the nature, of some of the changes, are different, according as the passage through the canal is slower, or quicker; they are different, according to the state of the organs, and according to the nature of the food.
Of the multitude of sensations, which must attend this process, very few become objects of attention; and, in time, an incapacity is generated, of making them objects of attention. They are not, however, as we shall afterwards perceive, feeble agents, or insignificant elements, in the trains of thought. They are of that class of feelings, to which we have already been under the necessity of alluding; a class, which serve as antecedents, to feelings more interesting than themselves; and from which the attention is so instantaneously drawn, to the more interesting feelings by which they are succeeded, that we are as little sensible of their existence, as we often are of the46sound of the clock, which may strike in the room beside us, and of course affect our ear in the usual manner, and yet leave no trace of the sensations behind.
The complicated sensations in the intestinal canal, like those in the muscles, though obscure, and even unknown, as individual sensations, often constitute a general state of feeling, which is sometimes exhilarating, and sometimes depressing. The effects of opium, and of inebriating liquors, in producing exhilaration, are well known; and though much of the pleasure in these states is owing to association, as we shall afterwards explain, yet the agreeable feelings in the stomach, are the origin and cause of the joyous associations.16The state of feeling in the stomach in seasickness, or under the operation of an emetic, is, on the contrary, one of the most distressing within our experience; though we can neither call it a pain, nor have any more distinct conception of it, than as a state of general uneasiness.
16The exact mode of operation of opium and alcohol is still unknown; but the part affected is probably the nervous substance and not the stomach. It can hardly be said with propriety that any part of the pleasure of these stimulants is due to association. No doubt the exhilarated tone of the mind is favourable to the flow of joyful ideas, which serve to heighten the pleasure; but that pleasure could not be arrested or subdued through the absence of any supposable associations.—B.

The general effects of indigestion are well known. When the organs of digestion become disordered, and indigestion becomes habitual, a sense of wretchedness is the consequence; a general state of feeling composed of a multitude of minor feelings, none of47which individually can be made an object of attention.
In the sense of wretchedness, which accompanies indigestion, and which sometimes proceeds to the dreadful state of melancholy madness, it is difficult to say, how much is sensation, and how much association. One thing is certain; that sensations which are the origin of so much misery are of high importance to us; whether they, or the associations they introduce, are the principal ingredient in the afflicting state which they contribute to create.
The effects of indigestion in producing painful associations, is strikingly exemplified by the horrible dreams which it produces in sleep; not only in those whose organs are diseased; but in the most healthy state of the stomach, when it has received what, in ordinary language, is said, whether from quantity or quality, to have disagreed with it.
The general states of feeling composed of the multitude of obscure and unnoticed feelings in the alimentary canal, though most apt to be noticed when they are of the painful kind, are not less frequently of the pleasurable kind. That particular sorts of foods, as well as liquors, have an exhilarating effect, needs hardly to be stated. And it is only necessary to revive the recollection of the feeling of general comfort, the elasticity, as it seems, of the whole frame, the feeling of strength, the disposition to activity and enjoyment, which every man must have experienced, when his digestion was vigorous and sound.17
17These effects pass beyond the influence of mere digestion. All the viscera contribute to the condition of high general48vigour and comfort here supposed. If one were to venture upon a scale of relative importance of the different organs, one would place the nervous centres first, and the digestion second.The present section is open to several remarks. Some qualification must be given to the author’s surmise ‘that a perpetual train of sensations is going on in every part of the alimentary canal.’ It is hardly correct to say that there are perpetual sensations inanypart of it: during a great part of our time we are in a state of indifference as to stomachic changes; and not merely because we are not disposed to attend to them, but because they scarcely exist. The sensibility of the organ is shown, on anatomical grounds, to be mainly in the stomach, and in the rectum; these parts are supplied by the nervus vagus; and very few nerves, besides those of the sympathetic system, are found in the smaller, or in the larger intestine, so that the sensitiveness of those parts is manifested only in case of violent disorganization, as cramp, stoppage, or inflammation. Hence the feelings are principally attendant on the changes in the stomach, as when food has just been taken, and after long privation, when the state called hunger shows itself.It is not correct to class the sensations of the alimentary canal, as a whole, with those that lose their hold of the attention, that become unheeded in themselves, and are valued only as the antecedents of other more pleasurable feelings. The remark is inapplicable to the sensations mainly characterized as pleasure or pain; nothing can be more interesting than a pleasure, except a still greater pleasure. It applies only to those slight irritations that are in themselves nothing, but may be the symptoms or precursors of ill health, or of returning good health.The author’s doctrine as to our acquiring artificially the habit of not attending to alimentary states, demands a fuller explanation. The usual cause of inattention to impressions is unbroken continuance; in accordance with the universal law49of Relativity or Change, we are usually insensible to the contact of our clothing with the skin, except at the moments when we put on or take off any part of it. In walking, and in standing, for a length of time, we are insensible to the body’s weight; on rising from the recumbent position we are rendered in some degree conscious of it. Now as the alimentary sensations—Hunger and Repletion—are intermitted and alternated with other states, they fulfil the chief condition of wakeful consciousness.The example of the striking of the clock, adduced in the text, brings into operation a different power of the mind, which may go far to counteract the influence of change. Under a very engrossing sensation, or occupation, we become insensible to the stimulation of the senses by other agents. The strain of the mind in some one direction causes a sort of incapacity for going out in any other direction while the strain lasts. This is the explanation of the indifference to the striking of the clock. By the farther influence of habit, inattention to a certain class of impressions may become habitual; as in the power of carrying on mental work in the midst of distracting noises.The same effect may arise in connection with the alimentary feelings. A person very much engrossed with a subject is unconscious of hunger, and does not feel the pleasures of eating. Should any one be absorbed habitually with some occupation or pursuit, such an one may contract a settled indifference to the recurring phases of alimentary sensation; but this is an extreme and unusual case. Any ordinary degree of interest in the avocations and pursuits of business is compatible with full attention to the feelings of hunger, and of repletion, as well as to the occasional pains and discomforts of indigestion. We do not often choose to contract an indifference to pleasures, and we seldom succeed in acquiring an indifference to pains, although we may have moments of such indifference, under some special engrossment of mind by other things.It is over-rating the influence of association to make it a50chief element in the pleasure of intoxicating stimulants, or in the wretched feelings of diseased digestion. These states are direct results of physical agency, and are the same throughout all stages of life, with many or with few opportunities of being associated with other feelings. They are not the cases favourable for illustrating the power of association, in the important department of the feelings.—B.

“Hæc in genere sors esse solet humana, ut quid in quovis genere recte aut cogitari aut effici possit sentiant prius quam perspiciant. Laborem autem haud ita levem illum veriti, qui in eo impendendus erat ut, ideas operatione analytica penitus evolventes, quid tandem velint, aut quænam res agatur, sibi ipsis rationem sufficientem reddant, confusis, aut saltem haud satia explicatis rationibus, ratiocinia, et scientiarum adeo systemata superstruere solent communiter, eoque confidentius, quo ejus quam tractant scientiæ fundamentum solidum magis ignorant.”—Schmidt-Phiseldek,Philos. Criticæ Expositio Systematica, t. i. p. 561.
“Pour systematiser une science, c’est-à-dire, pour ramener une suite de phénomènes à leur principe, à un phénomène élémentaire qui engendre successivement tous les autres, il faut saisir leurs rapports, le rapport de génération qui les lie; et pour cela, il est clair qu’il faut commencer par examiner ces différens phénomènes séparément.”—Cousin,Fragm. Philos., p. 8.
THEsensations which we have through the medium of the senses exist only by the presence of the object, and cease upon its absence; nothing being here meant by the presence of the object, but that position of it with respect to the organ, which is the antecedent of the sensation; or by its absence, but any other position.
It is a known part of our constitution, that when our sensations cease, by the absence of their objects, something remains. After I have seen the sun, and52by shutting my eyes see him no longer, I can still think of him. I have still a feeling, the consequence of the sensation, which, though I can distinguish it from the sensation, and treat it as not the sensation, but something different from the sensation, is yet more like the sensation, than anything else can be; so like, that I call it a copy, an image, of the sensation; sometimes, a representation, or trace, of the sensation.
Another name, by which we denote this trace, this copy, of the sensation, which remains after the sensation ceases, isIDEA. This is a very convenient name, and it is that by which the copies of the sensation thus described will be commonly denominated in the present work. The wordIDEA, in this sense, will express no theory whatsoever; nothing but the bare fact, which is indisputable. We have two classes of feelings; one, that which exists when the object of sense is present; another, that which exists after the object of sense has ceased to be present. The one class of feelings I callSENSATIONS; the other class of feelings I callIDEAS.
It is an inconvenience, that the wordIDEAis used with great latitude of meaning, both in ordinary, and in philosophical discourse; and it will not be always expedient that I should avoid using it in senses different from that which I have now assigned. I trust, however, I shall in no case leave it doubtful, in what sense it is to be understood.
The term Sensation has a double meaning. It signifies not only an individual sensation; as when I say, I smell this rose, or I look at my hand: but it also signifies the general faculty of sensation; that is,53the complex notion of all the phenomena together, as a part of our nature.
The word Idea has only the meaning which corresponds to the first of those significations; it denotes an individual idea; and we have not a name for that complex notion which embraces, as one whole, all the different phenomena to which the term Idea relates. As we say Sensation, we might say also, Ideation; it would be a very useful word; and there is no objection to it, except the pedantic habit of decrying a new term. Sensation would in that case be the general name for one part of our constitution, Ideation for another.
It is of great importance, before the learner proceeds any farther, that he should not only have an accurate conception of this part of his constitution; but should acquire, by repetition, by complete familiarity, a ready habit of marking those immediate copies of his sensations, and of distinguishing them from every other phenomenon of his mind.
It has been represented, that the sensations of sight and hearing leave the most vivid traces; in other words, that the ideas corresponding to those sensations, are clearer than others. But what is meant by clearer and more vivid in this case, is not very apparent.
If I have a very clear idea of the colour of the trumpet which I have seen, and a very clear idea of its sound which I have heard, I have no less clear ideas of its shape, and of its size; ideas of the sensations, neither of the eye, nor of the ear.
It is not easy, in a subject like this, to determine what degree of illustration is needful. To those who are in the habit of distinguishing their mental54phenomena, the subject will appear too simple to require illustration. To those who are new to this important operation, a greater number of illustrations would be useful, than I shall deem it advisable to present.
It is necessary to take notice, that, as each of our senses has its separate class of sensations, so each has its separate class of ideas. We have ideas of Sight, ideas of Touch, ideas of Hearing, ideas of Taste, and ideas of Smell.
1. By Sight, as we have sensations of red, yellow, blue, &c., and of the innumerable modifications of them, so have we ideas of those colours. We can think of those colours in the dark; that is, we have a feeling or consciousness, which is not the same with the sensation, but which we contemplate as a copy of the sensation, an image of it; something more like it, than any thing else can be; something which remains with us, after the sensation is gone, and which, in the train of thought, we can use as its representative.
2. The sensations of Touch, according to the limitation under which they should be understood, are not greatly varied. The gentle feeling, which we derive from the mere contact of an object, when we consider it apart from the feeling of resistance, and apart from the sensation of heat or cold, is not very different, as derived from different objects. The idea of this tactual feeling, therefore, is not vivid, nor susceptible of many modifications. On the other hand, our ideas of heat and cold, the feelings which we call the thought of them, existing when the sensations no longer exist, are among the most distinct of the feelings which we distinguish by the name of ideas.
553. I hear the Sound of thunder; and I can think of it after it is gone. This feeling, the representative of the mere sound, this thinking, or having the thought of the sound, this state of consciousness, is the idea. The hearing of the sound is the primary state of consciousness; the idea of the sound is the secondary state of consciousness; which exists only when the first has previously existed.
The number of sounds, of which we can have distinct ideas, as well as distinct sensations, is immense. We can distinguish all animals by their voices. When I hear the horse neigh, I know it is not the voice of the ox. Why? Because I have the idea of the voice of the ox, so distinct, that I know the sensation I have, is different from the sensation of which that is the copy or representative. We can distinguish the sounds of a great number of different musical instruments, by the same process. The men, women, and children, of our intimate acquaintance, we can distinguish, and name, by their voices; that is, we have an idea of the past sensation, which enables us to declare, that the present is the voice of the same person.
4. That the sensations of Taste recur in thought, when the sensation no longer exists, is a point of every man’s experience. This recurring, in thought, of the feeling which we have by the sense, when the feeling by the sense is gone, is the idea of that feeling, the secondary state of consciousness, as we named it above.18That we can distinguish a very56great number of tastes, and distinguish them accurately, is proof that we have a vast number of distinct ideas of taste; because, for the purpose of making such distinction, we have just seen that there must be a sensation and an idea; the sensation of the present object, and the idea of the sensation of each of the other objects from which we distinguish it. You have tasted port wine, and you have tasted claret; when you taste claret again, you can distinguish it from port wine; that is, you have the idea of the taste of port wine, in conjunction with the sensation of claret. You call it bad claret. Why? Because, along with the present taste, you have the idea of another, which, when it was sensation, was more agreeable than the present sensation.
18Discrimination and Retentiveness (the having of Ideas as the produce of Sensations) are different functions, although mutually involved, and, in all likelihood, developed in proportionate degrees in the same organ. We begin by discriminating changes of impression; this process is necessary in order to our having even a sensation; the more delicate the discriminating power, the greater the number of our primary sensations. He that can discriminate twenty shades of yellow has twenty sensations of yellow; the two statements express the same fact. These various sensations being often repeated, acquire at last an ideal persistence; they can be maintained as ideas, without the originals. The function or power of the Intellect whereby they are thus rendered self-subsisting as ideas, is not the same function as discrimination; we call it Memory, Retentiveness, Adhesiveness, Association, and so on. What may be affirmed about it, on the evidence of induction, is, that where discrimination is good, memory or retentiveness is also good. The discriminative eye for colour is accompanied with a good memory for colour; the musical ear is both discriminative and retentive.—B.

5. Since we distinguish smells, as well as tastes,57we have the same proof of the number and distinctness of the ideas of this class of sensations. There is none of the numerous smells to which we have been accustomed, which we do not immediately recognise. But for that recognition the idea of the past sensation must be conjoined with the present sensation.
6. Of that class of sensations, which I have called sensations of disorganization, we have also ideas. We are capable of having the thought of them when the sensation is gone; and that thought is the idea. A spark from the candle flew upon my hand: I had the sensation of burning. I at this moment think of that sensation; that is, I have the idea of that sensation; and I can think of it, as different from ten thousand other painful sensations: that is, I have ideas of as many other sensations of this class.
7. The ideas of the sensations which attend the action of the muscles are among the most important of the elements which constitute our being. From these we have the ideas of resistance, of compressibility, of hardness, of softness, of roughness, of smoothness, of solidity, of liquidity, of weight, of levity, of extension, of figure, of magnitude, of whole and of parts, of motion, of rest. It is, indeed, to be observed, that these are all complex ideas, and that other feelings than the mere muscular feeling are concerned in their composition. In almost all the ideas referrible to the muscular feelings, of sufficient importance to have names, the Will is included. The muscular action is the consequent, the Will the antecedent; and the name of the idea, includes both. Thus the idea of resistance is the thought, or idea, of58the feelings we have, when we will to contract certain muscles, and feel the contraction impeded.1920
19Rather, when we will to contract certain muscles, and the contraction takes place, but is not followed by the accustomed movement of the limb; what follows, instead, being a sensation of pressure, proportioned to the degree of the contraction. It is not the muscular contraction itself which is impeded by the resisting object: that contraction takes place: but the outward effect which it was the tendency, and perhaps the purpose, of the muscular contraction to produce, fails to be produced.—Ed.

20It is unnecessary to advert to the operation of the Will, (in the first instance at least,) in considering the feelings of muscular action. The will is the principal, but not the only, source of our activity. The mere spontaneous vigour of the system may put the muscles in motion. Likewise the muscular pleasure itself operates, by the fundamental law of the will, for its own continuance; a process not commonly called voluntary. In these circumstances, it seems advisable to consider and describe the consciousness of muscular exertion by itself, and without reference to the will.—B.

There is no feeling of our nature of more importance to us, than that of resistance. Of all our sensations, it is the most unintermitted; for, whether we sit, or lie, or stand, or walk, still the feeling of resistance is present to us. Every thing we touch, at the same time resists; and every thing we hear, see, taste, or smell, suggests the idea of something that resists. It is through the medium of resistance, that every act by which we subject to our use the objects and laws of nature, is performed. And, of the complex states of consciousness, which the philosophy of mind is called upon to explain, there is hardly one, in which the feeling or idea of resistance is not included.
It is partly owing to this combination of something59else with the muscular feeling, in all the states of consciousness to which we have given names, that it is so difficult to think of the mere muscular feeling by itself; that our notion of the muscular sensations is so indistinct and obscure; and that we can rather be said to have ideas of certain general states of muscular feeling, as of fatigue, or activity, composed of a great number of individual feelings, than of the individual feelings themselves.
8. As the feelings, or sensations which we have in the intestinal canal, are almost always mixed up indistinctly with other feelings, and, except in the cases of acute pain, are seldom taken notice of but as constituting general states, we hardly have the power of thinking of those sensations one by one; and, in consequence, can hardly be said to have ideas of them. They are important, as forming component parts of many complex ideas, which have great influence on our happiness. But to unfold the mystery of complex ideas, other parts of our mental process have yet to be explained.
There is a certain distressful feeling, called the feeling of bad health, which is considerably different in different cases, but in which sensations of the intestinal canal are almost always a material part.
Indigestion is the name of an idea, in which the feelings of the intestinal canal are mainly concerned.
