BOOK II: Of Ideas

Chapter I Of Ideas in General, and their Original Chapter II Of Simple Ideas

§1. Idea is the object of thinking. Every man being conscious to himself, that he thinks, and that which his mind is applied about,whilst thinking, being the ideas, that are there, ’tis past doubt, that men have in their minds several ideas, such as are those expressed by the words, whiteness, hardness, sweetness, thinking, motion, man,elephant, army, drunkenness, and others: ’tis in the first place then to be inquired, How he comes by them‘ I know ’tis a received doctrine,that men have native ideas, and original characters stamped upon their minds, in their very first being. This opinion I have at large examined already; and, I suppose, what I have said in the foregoing book, will be much more easily admitted, when I have shown,whence the understanding may get all the ideas it has, and by what ways and degrees they may come into the mind; for which I shall appeal to everyone’s own observation and experience.

§2. All ideas come from sensation or reflection. Let us then suppose the mind to be, as we say, white paper, void of all characters,without any ideas: How comes it to be furnished‘ Whence comes it by that vast store, which the busy and boundless fancy of man has painted on it, with an almost endless variety‘ Whence has it all the materials of reason and knowledge‘ To this I answer, in one word,from experience. In that, all our knowledge is founded; and from that it ultimately derives itself. Our observation employed either about external sensible objects; or about the in ternal operations of our minds, perceived and reflected on by ourselves, is that, which supplies our understandings with all the materials of thinking. These two are the fountains of knowledge, from whence all the ideas we have, or can naturally have, do spring.

§3. The objects of sensation one source of ideas. First, our senses,conversant about particular sensible objects, do convey into the mind,several distinct perceptions of things, according to those various ways,wherein those objects do affect them: and thus we come by those ideas we have of yellow, white, heat, cold, soft, hard, bitter, sweet, and all those which we call sensible qualities, which when I say the senses convey into the mind, I mean, they from external objects convey into the mind what produces there those perceptions. This great source, of most of the ideas we have, depending wholly upon our senses, and derived by them to the understanding, I call sensation.

§4. The operations of our minds, the other source of them.Secondly, the other fountain, from which experience furnisheth the understanding with ideas, is the perception of the operations of our own mind within us, as ’tis employed about the ideas it has got;which operations, when the soul comes to reflect on, and consider,do furnish the understanding with another set of ideas, which could not be had from things without; and such are, perception,thinking, doubting, believing, reasoning, knowing, willing, and all the different actings of our own minds; which we being conscious of, and observing in ourselves, do from these receive into our understandings, as distinct ideas, as we do from bodies affecting our senses. This source of ideas, every man has wholly in himself:and though it be not sense, as having nothing to do with external objects; yet ’tis very like it, and might properly enough be called internal sense. But as I call the other sensation, so I call this reflection,the ideas it affords being such only, as the mind gets by reflecting on its own operations within itself. By reflection then, in the following part of this discourse, I would be understood to mean, that notice which the mind takes of its own operations, and the manner of them,by reason whereof, there come to be ideas of these operations in the understanding. These two, I say, viz. external, material things, as the objects of sensation; and the operations of our own minds within, as the objects of reflection, are, to me, the only originals, from whence all our ideas take their beginnings. The term operations here, I use in a large sense, as comprehending not barely the actions of the mind about its ideas, but some sort of passions arising sometimes from them,such as is the satisfaction or uneasiness arising from any thought.

§5. All our ideas are of the one or the other of these. The understanding seems to me, not to have the least glimmering of any ideas, which it doth not receive from one of these two. External objects furnish the mind with the ideas of sensible qualities, which are all those different perceptions they produce in us: and the mind furnishes the understanding with ideas of its own operations.These, when we have taken a full survey of them, and their several modes, combinations, and relations, we shall find to contain all our whole stock of ideas; and that we have nothing in our minds,which did not come in, one of these two ways. Let anyone examine his own thoughts, and thoroughly search into his understanding, and then let him tell me, whether all the original ideas he has there, are any other than of the objects of his senses; or of the operations of his mind, considered as objects of his reflection: and how great a mass of knowledge soever he imagines to be lodged there, he will, upon taking a strict view, see that he has not any idea in his mind, but what one of these two have imprinted; though, perhaps, with infinite variety compounded and enlarged by the understanding, as we shall see hereafter.

§6. Observable in children. He that attentively considers the state of a child, at his first coming into the world, will have little reason to think him stored with plenty of ideas, that are to be the matter of his future knowledge. ’Tis by degrees he comes to be furnished with them: and though the ideas of obvious and familiar qualities, imprint themselves, before the memory begins to keep a register of time and order, yet ’tis often so late, before some unusual qualities come in the way, that there are few men that cannot recollect the beginning of their acquaintance with them: and if it were worth, while, no doubt a child might be so ordered, as to have but a very few, even of the ordinary ideas, till he were grown up to a man. But all that are born into the world being surrounded with bodies, that perpetually and diversely affect them, variety of ideas, whether care be taken about it or no, are imprinted on the minds of children. Light and colours, are busy at hand everywhere, when the eye is but open; sounds and some tangible qualities fail not to solicit their proper senses, and force an entrance to the mind; but yet, I think, it will be granted easily, that if a child were kept in a place, where he never saw any other but black and white, till he were a man, he would have no more ideas of scarlet or green, than he that from his childhood never tasted an oyster, or a pineapple, has of those particular relishes.

§7. Men are differently furnished with these, according to the different objects they converse with. Men then come to be furnished with fewer or more simple ideas from without, according as the objects they converse with, afford greater or less variety; and from the operations of their minds within, according as they more or less reflect on them. For, though he that contemplates the operations of his mind, cannot but have plain and clear ideas of them; yet unless he turn his thoughts that way, and considers them attentively, he will no more have clear and distinct ideas of all the operations of his mind, and all that may be observed therein, than he will have all the particular ideas of any landscape, or of the parts and motions of a clock, who will not turn his eyes to it, and with attention heed all the parts of it. The picture, or clock may be so placed, that they may come in his way every day; but yet he will have but a confused idea of all the parts they are made up of, till he applies himself with attention, to consider them each in particular.

§8. Ideas of reflection later, because they need attention. And hence we see the reason, why ’tis pretty late, before most children get ideas of the operations of their own minds; and some have not any very,clear, or perfect ideas of the greatest part of them all their lives.Because, though they pass there continually; yet like floating visions,they make not deep impressions enough, to leave in the mind clear distinct lasting ideas, till the understanding turns inwards upon itself,reflects on its own operations, and makes them the object of its own contemplation. Children, when they come first into it, are surrounded with a world of new things, which, by a constant solicitation of their senses, draw the mind constantly to them, forward to take notice of new, and apt to be delighted with the variety of changing objects.Thus the first years are usually employed and diverted in looking abroad. Men’s business in them is to acquaint themselves with what is to be found without; and so growing up in a constant attention to outward sensations, seldom make any considerable reflection on what passes within them, till they come to be of riper years; and some scarce ever at all.

§9. The soul begins to have ideas when it begins to perceive. To ask,at what time a man has first any ideas, is to ask, when he begins to perceive; having ideas, and perception, being the same thing. I know ’tis an opinion, that the soul always thinks, and that it has the actual perception of ideas in itself constantly, as long as it exists; and that actual thinking is as inseparable from the soul, as actual extension is from the body; which if true, to inquire after the beginning of a man’s ideas, is the same, as to inquire after the beginning of his soul. For by this account, soul and its ideas, as body and its extension, will begin to exist both at the same time.

§10. The soul thinks not always; for this wants proofs. But whether the soul be supposed to exist antecedent to, or coeval with, or some time after the first rudiments of organization, or the beginnings of life in the body, I leave to be disputed by those, who have better thought of that matter. I confess myself, to have one of those dull souls, that doth not perceive itself always to contemplate ideas;nor can conceive it any more necessary for the soul always to think,than for the body always to move; the perception of ideas being (as I conceive) to the soul, what motion is to the body, not its essence, but one of its operations: and therefore, though thinking be supposed never so much the proper action of the soul; yet ’tis not necessary, to suppose, that it should be always thinking, always in action. That, perhaps, is the privilege of the infinite Author and Preserver of things, ‘who never slumbers nor sleeps’ but is not competent to any finite being, at least not to the soul of man. We know certainly by experience, that we sometimes think, and thence draw this infallible consequence, that, there is something in us, that has a power to think, but whether that substance perpetually thinks,or no, we can be no further assured, than experience informs us. For to say, that actual thinking is essential to the soul, and inseparable from it, is to beg, what is in question, and not to prove it by reason;which is necessary to be done, if it be not a self evident proposition.But whether this, ‘that the soul always thinks’ be a self evident proposition, that everybody assents to at first hearing, I appeal to mankind. ’Tis doubted whether I thought all last night, or no; the question being about a matter of fact, ’tis begging it to bring, as a proof for it, an hypothesis, which is the very thing in dispute; by which way one may prove anything, and ’tis but supposing that all watches, whilst the balance beats, think, and ’tis sufficiently proved,and past doubt, that my watch thought all last night. But he, that would not deceive himself, ought to build his hypothesis on matter of fact, and make it out by sensible experience, and not presume on matter of fact, because of his hypothesis, that is, because he supposes it to be so; which way of proving, amounts to this, that I must necessarily think all last night, because another supposes I always think, though I myself cannot perceive, that I always do so.But men in love with their opinions, may not only suppose what is in question, but allege wrong matter of fact. How else could anyone make it an inference of mine, that a thing is not, because we are not sensible of it in our sleep‘ I do not say there is no soul in a man,because he is not sensible of it in his sleep: but I do say, he cannot think at any time waking or sleeping, without being sensible of it. Our being sensible of ’tis not necessary to anything, but to our thoughts; and to them ’tis, and to them it will always be necessary,till we can think without being conscious of it.

§11. ’Tis not always conscious of it. I grant that the soul in a waking man, is never without thought because ’tis the condition of being awake, but whether sleeping without dreaming be not an affection of the whole man, mind as well as body, may be worth a waking man’s consideration; it being hard to conceive, that anything should think, and not be conscious of it. If the soul doth think in a sleeping man, without being conscious of it, I ask, whether, during such thinking, it has any pleasure or pain, or be capable of happiness or misery‘ I am sure the man is not, no more than the bed or earth he lies on. For to be happy or miserable without being conscious of it, seems to me utterly inconsistent and impossible. Or if it be possible, that the soul can, whilst the body is sleeping, have its thinking, enjoyments,and concerns, its pleasures or pain apart, which the man is not conscious of, nor partakes in: ’tis certain, that Socrates asleep,and Socrates awake, is not the same person: but his soul when he sleeps, and Socrates the man consisting of body and soul when he is waking, are two persons; since waking Socrates, has no knowledge of, or concernment for that happiness, or misery of his soul, which it enjoys alone by itself whilst he sleeps, without perceiving anything of it; no more than he has for the happiness, or misery of a man in the Indies, whom he knows not. For if we take wholly away all consciousness of our actions and sensations, especially of pleasure and pain, and the concernment that accompanies it, it will be hard to know wherein to place personal identity.

§12. If a sleeping man thinks without knowing it, the sleeping and waking man are two persons. The soul, during sound sleep, thinks,say these men. Whilst it thinks and perceives, ’tis capable certainly of those of delight or trouble, as well as any other perceptions; and it must necessarily be conscious of its own perceptions. But it has all this apart: the sleeping man, ’tis plain, is conscious of nothing of all this.

Let us suppose then the soul of Castor, while he is sleeping, retired from his body, which is no impossible supposition for the men I have here to do with, who so liberally allow life, without a thinking soul to all other animals. These men cannot then judge it impossible,or a contradiction, that the body should live without the soul; nor that the soul should subsist and think, or have perception, even perception of happiness or misery, without the body. Let us then, as I say, suppose the soul of Castor separated, during his sleep, from his body, to think apart. Let us suppose too, that it chooses for its scene of thinking, the body of another man, v.g. Pollux, who is sleeping without a soul: for if Castor’s soul can think whilst Castor is asleep,what Castor is never conscious of, ’tis no matter what place it chooses to think in. We have here then, the bodies of two men with only one soul between them, which we will suppose to sleep and wake by turns;and the soul still thinking in the waking man, whereof the sleeping man is never conscious, has never the least perception. I ask, then,whether Castor and Pollux, thus, with only one soul between them,which thinks and perceives in one, what the other is never conscious of, nor is concerned for, are not two as distinct persons, as Castor and Hercules; or, as Socrates and Plato were‘ And whether one of them might not be very happy, and the other very miserable‘ Just by the same reason, they make the soul and the man two persons, who make the soul think apart, what the man is not conscious of. For, I suppose, nobody will make identity of persons, to consist in the soul’s being united to the very same numercial particles of matter: for if that be necessary to identity, it will be impossible, in that constant flux of the particles of our bodies, that any man should be the same person, two days, or two moments together.

§13. Impossible to convince those that sleep without dreaming, that they think. Thus, methinks, every drowsy nod shakes their doctrine,who teach, that the soul is always thinking. Those, at least, who do at any time sleep without dreaming, can never be convinced, that their thoughts are sometimes for four hours busy without their knowing of it; and if they are taken in the very act, waked in the middle of that sleeping contemplation, can give no manner of account of it.

§14. That men dream without remembering it, in vain urged.It will perhaps be said, that the soul thinks, even in the soundest sleep, but the memory retains it not. That the soul in a sleeping man should be this moment busy a thinking, and the next moment in a waking man, not remember, nor be able to recollect one jot of all those thoughts, is very hard to be conceived, and would need some better proof than bare assertion, to make it be believed. For who can without any more ado, but being barely told so, imagine, that the greatest part of men, do, during all their lives, for several hours every day, think of something, which if they were asked, even in the middle of these thoughts, they could remember nothing at all of‘ Most men, I think, pass a great part of their sleep without dreaming. I once knew a man, that was bred a scholar, and had no bad memory, who told me,he had never dreamed in his life, till he had that fever, he was then newly recovered of, which was about the five or six and twentieth year of his age. I suppose the world affords more such, instances: at least everyone’s acquaintance will furnish him with examples enough of such as pass most of their nights without dreaming.

§15. Upon this hypothesis, the thoughts of a sleeping man ought to be most rational. To think often, and never to retain it so much as one moment, is a very useless sort of thinking: and the soul in such a state of thinking, does very little if at all, excel that of a looking-glass,which constantly receives variety of images, or ideas, but retains none; they disappear and vanish, and there remain no footsteps of them; the looking-glass is never the better for such ideas, nor the soul for such thoughts. Perhaps it will be said, that in a waking man, the materials of the body are employed, and made use of, in thinking;and that the memory of thoughts, is retained by the impressions that are made on the brain, and the traces there left after such thinking;but that in the thinking of the soul, which is not perceived in a sleeping man, there the soul thinks apart, and making no use of the organs of the body, leaves no impressions on it, and consequently no memory of such thoughts. Not to mention again the absurdity of two distinct persons, which follows from this supposition, I answer further, that whatever ideas the mind can receive, and contemplate without the help of the body, ’tis reasonable to conclude, it can retain without the help of the body too, or else the soul, or any separate spirit will have but little advantage by thinking. If it has no memory of its own thoughts; if it cannot lay them up for its use, and be able to recall them upon occasion; if it cannot reflect upon what is past, and make use of its former experiences, reasonings, and contemplations, to what purpose does it think‘ They, who make the soul a thinking thing, at this rate, will not make it a much more noble being, than those do,whom they condemn, for allowing it to be nothing but the subtilist parts of matter. Characters drawn on dust, that the first breath of wind effaces; or impressions made on a heap of atoms, or animal spirits, are altogether as useful, and render the subject as noble, as the thoughts of a soul that perish in thinking; that once out of sight,are gone forever, and leave no memory of themselves behind them.

Nature never makes excellent things, for mean or no uses: and ’tis hardly to be conceived, that our infinitely wise Creator, should make so admirable a faculty, as the power of thinking, that faculty which comes nearest the excellency of his own incomprehensible being,to be so idly and uselessly employed, at least a fourth part of its time here, as to think constantly, without remembering any of those thoughts, without doing any good to itself or others, or being any way useful to any other part of the creation. If we will examine it, we shall not find, I suppose, the motion of dull and senseless matter, anywhere in the universe, made so little use of, and so wholly thrown away.

§16. On this hypothesis the soul must have ideas not derived from sensation or reflection, of which there is no appearance. ’Tis true,we have sometimes instances of perception, whilst we are asleep,and retain the memory of those thoughts: but how extravagant and incoherent for the most part they are; how little conformable to the perfection and order of a rational being, those who are acquainted with dreams, need not be told. This I would willingly be satisfied in,whether the soul, when it thinks thus apart, and as it were separate from the body, acts less rationally than when conjointly with it, or no: if its separate thoughts be less rational, then these men must say,that the soul owes the perfection of rational thinking to the body:if it does not, ’tis a wonder that our dreams should be, for the most part, so frivolous and irrational; and that the soul should retain none of its more rational soliloquies and meditations.

§17. If I think when I know it not, nobody else can know it. Those who so confidently tell us, that the soul always actually thinks, I would they would also tell us, what those ideas are, that are in the soul of a child, before, or just at the union with the body, before it hath received any by sensation. The dreams of sleeping men are, as I take it, all made up of the waking man’s ideas, though, for the most part, oddly put together. ’Tis strange, if the soul has ideas of its own that it derived not from sensation or reflection, (as it must have, if it thought before it received any impressions from the body) that it should never, in its private thinking, (so private, that the man himself perceives it not) retain any of them, the very moment it wakes out of them, and then make the man glad with new discoveries.

Who can find it reasonable that the soul should, in its retirement,during sleep, have so many hours thoughts, and yet never light on any of those ideas it borrowed not from sensation or reflection; or at least preserve the memory of none, but such, which being occasioned from the body, must needs be less natural to a spirit‘ ’Tis strange,the soul should never once in a man’s whole life, recall over any of its pure, native thoughts, and those ideas it had before it borrowed anything from the body; never bring into the waking man’s view, any other ideas, but what have a tang of the cask, and manifestly derive their original from that union. If it always thinks, and so had ideas before it was united, or before it received any from the body, ’tis not to be supposed, but that during sleep, it recollects its native ideas, and during that retirement from communicating with the body, whilst it thinks by itself, the ideas, ’tis busied about, should be, sometimes at least, those more natural and congenial ones which it had in itself, underived from the body, or its own operations about them:which since the waking man never remembers, we must from this hypothesis conclude, either that the soul remembers something that the man does not; or else that memory belongs only to such ideas, as are derived from the body, or the mind’s operations about them.

§18. How knows anyone that the soul always thinks‘ For if it be not a self-evident proposition, it needs proof. I would be glad also to learn from these men, who so confidently pronounce, that the human soul, or which is all one, that a man always thinks, how they come to know it; nay, how they come to know that they themselves think,when they themselves do not perceive it. This I am afraid, is to be sure,without proofs; and to know, without perceiving. ’Tis, I suspect, a confused notion, taken up to serve an hypothesis; and none of those clear truths, that either their own evidence forces us to admit, or common experience makes it impudence to deny. For the most that can be said of it, is, that ’tis possible the soul may always think, but not always retain it in memory: and, I say, ’tis as possible, that the soul may not always think; and much more probable, that it should sometimes not think, than that it should often think, and that a long while together, and not be conscious to itself the next moment after,that it had thought.

§19. That a man should be busy in thinking, and yet not retain it the next moment, very improbable. To suppose the soul to think, and the man not to perceive it, is, as has been said, to make two persons in one man: and if one considers well these men’s way of speaking, one should be led into a suspicion, that they do so. For they who tell us that the soul always thinks, do never, that I remember, say, that a man always thinks. Can the soul think, and not the man‘ Or a man think, and not be conscious of it‘ This perhaps, would be suspected of jargon in others. If they say, the man thinks always, but is not always conscious of it; they may as well say, his body is extended,without having parts. For ’tis altogether as intelligible to say, that a body is extended without parts, as that anything thinks without being conscious of it, or perceiving, that it does so. They who talk thus,may, with as much reason, if it be necessary to their hypothesis,say, that a man is always hungry, but that he does not always feel it: whereas hunger consists in that very sensation, as thinking consists in being conscious that one thinks. If they say, that a man is always conscious, to himself of thinking; I ask, how they know it‘

Consciousness is the perception of what passes in a man’s own mind.Can another man perceive, that I am conscious of anything, when I perceive it not myself‘ No man’s knowledge here, can go beyond his experience. Wake a man out of a sound sleep, and ask him, what he was that moment thinking on‘ If he himself be conscious of nothing he then thought on, he must be a notable diviner of thoughts, that can assure him, that he was thinking: may he not with more reason assure him, he was not asleep‘ This is something beyond philosophy;and it cannot be less than revelation, that discovers to another,thoughts in my mind, when I can find none there myself: and they must needs have a penetrating sight, who can certainly see, that I think, when I cannot perceive it myself, and when I declare, that I do not; and yet can see, that dogs or elephants do not think, when they give all the demonstration of it imaginable, except only telling us, that they do so. This some may suspect to be a step beyond the Rosicrucians; it seeming easier to make one, self invisible to others,than to make another’s thoughts visible to me, which are not visible to himself. But ’tis but defining the soul to be a substance, that always thinks, and the business is done. If such definition be of any authority,I know not what it can serve for, but to make many men suspect, that they have no souls at all, since they find a good part of their lives pass away without thinking. For no definitions, that I know, no suppositions of any sect, are of force enough to destroy constant experience; and perhaps, ’tis the affectation of knowing beyond what we perceive, that makes so much useless dispute, and noise, in the world.

§20. No ideas but from sensation and reflection, evident, if we observe children. I see no reason therefore to believe, that the soul thinks before the senses have furnished it with ideas to think on; and as those are increased, and retained; so it comes, by exercise, to improve its faculty of thinking in the several parts of it, as well as afterwards,by compounding those ideas, and reflecting on its own operations,it increases its stock as well as facility, in remembering, imagining,reasoning, and other modes of thinking.

§21. State of a child in the mother’s womb. He that will suffer himself, to be informed by observation and experience, and not make his own hypothesis the rule of nature, will find few signs of a soul accustomed to much thinking in a new-born child, and much fewer of any reasoning at all. And yet ’tis hard to imagine, that the rational soul should think so much, and not reason at all. And he that will consider, that infants, newly come into the world, spend the greatest part of their time in sleep, and are seldom awake, but when either hunger calls for the teat, or some pain, (the most importunate of all sensations) or some other violent impression on the body, forces the mind to perceive, and attend to it. He, I say,who considers this, will perhaps, find reason to imagine, that a foetus in the mother’s womb, differs not much from the state of a vegetable; but passes the greatest part of its time without perception or thought,doing very little, but sleep in a place, where it needs not seek for food, and is surrounded with liquor, always equally soft, and near of the same temper; where the eyes have no light, and the ears, so shut up, are not very susceptible of sounds; and where there is little or no variety, or change of objects, to move the senses.

§22. The mind thinks in proportion to the matter it gets from experience to think about. Follow a child from its birth, and observe the alterations that time makes, and you shall find, as the mind by the senses comes more and more to be furnished with ideas, it comes to be more and more awake; thinks more, the more it has matter to think on. After some time, it begins to know the objects, which being most familiar with it, have made lasting impressions. Thus it comes, by degrees, to know the persons it daily converses with, and distinguishes them from strangers; which are instances and effects of its coming to retain and distinguish the ideas the senses convey to it:and so we may observe, how the mind, by degrees, improves in these,and advances to the exercise of those other faculties of enlarging,compounding, and abstracting its ideas, and of reasoning about them,and reflecting upon all these, of which, I shall have occasion to speak more hereafter.

§23. A man begins to have ideas when he first has sensation.What sensation is. If it shall be demanded then, when a man begins to have any ideas‘ I think, the true answer is, when he first has any sensation. For since there appear not to be any ideas in the mind,before the senses have conveyed any in, I conceive that ideas in the understanding, are coeval with sensation; which is such an impression or motion, made in some part of the body, as produces some perception in the understanding. ’Tis about these impressions made on our senses by outward objects, that the mind seems first to employ itself in such operations as we call perception, remembering,consideration, reasoning, etc.

§24. The original of all our knowledge. In time, the mind comes to reflect on its own operations, about the ideas got by sensation,and thereby stores itself with a new set of ideas, which I call ideas of reflection. These are the impressions that are made on our senses by outward objects, that are extrinsical to the mind; and its own operations, proceeding from powers intrinsical and proper to itself, which when reflected on by itself, become also objects of its contemplation, are, as I have said, the original of all knowledge. Thus the first capacity of human intellect, is, that the mind is fitted to receive the impressions made on it; either, through the senses, by outward objects; or by its own operations, when it reflects on them.This is the first step a man makes towards the discovery of anything,and the groundwork, whereon to build all those notions, which ever he shall have naturally in this world. All those sublime thoughts,which tower above the clouds, and reach as high as heaven itself,take their rise and footing here: in all that great extent wherein the mind wanders, in those remote speculations, it may seem to be elevated with, it stirs not one jot beyond those ideas, which sense or reflection have offered for its contemplation.

§25. In the reception of simple ideas, the understanding is for the most part passive. In this part the understanding is merely passive; and whether or no, it will have these beginnings, and as it were materials of knowledge, is not in its own power. For the objects of our senses,do, many of them, obtrude their particular ideas upon our minds,whether we will or no: and the operations of our minds, will not let us be without, at least some obscure notions of them. No man can be wholly ignorant of what he does, when he thinks. These simple ideas, when offered to the mind, the understanding can no more refuse to have, nor alter, when they are imprinted, nor blot them out, and make new ones itself, than a mirror can refuse, alter, or obliterate the images or ideas, which, the objects set before it, do therein produce.As the bodies that surround us, do diversely affect our organs, the mind is forced to receive the impressions; and cannot avoid the perception of those ideas that are annexed to them.
