strengthening the relation of ideas, is often necessary to produce a relation of impressions, and give rise to pleasure and uneasiness. For it is observable, that the principal part of an injury is the contempt and hatred, which it shews in the person, that injures us; and without that, the mere harm gives us a less sensible uneasiness. In like manner, a good office is agreeable, chiefly because it flatters our vanity, and is a proof of the kindness and esteem of the person, who performs it.
The removal of the intention, removes the mortification in the one case, and vanity in the other, and must of course cause a remarkable diminution in the passions of love and hatred.
I grant, that these effects of the removal of design, in diminishing the relations of impressions and ideas, are not entire, nor able to remove every degree of these relations. But then I ask, if the removal of design be able entirely to remove the passion of love and hatred?
Experience, I am sure, informs us of the contrary, nor is there any thing more certain, than that men often fall into a violent anger for injuries, which they themselves must own to be entirely involuntary and accidental. This emotion, indeed, cannot be of long continuance; but still is sufficient to shew, that there is a natural connexion betwixt uneasiness and anger, and that the relation of impressions will operate upon a very small relation of ideas. But when the violence of the impression is once a little abated, the defect of the relation begins to be better felt; and as the character of a person is no wise interested in such injuries as are casual and involuntary, it seldom happens that on their account, we entertain a lasting enmity.
To illustrate this doctrine by a parallel instance, we may observe, that not only the uneasiness, which proceeds from another by accident, has but little force to excite our passion, but also that which arises from an acknowledged necessity and duty. One that has a real design of harming us, proceeding not from hatred and ill-will, but from justice and equity, draws not upon him our anger, if we be in any degree reasonable; notwithstanding he is both the cause, and the knowing cause of our sufferings. Let us examine a little this phænomenon.
It is evident in the first place, that this circumstance is not decisive; and though it may be able to diminish the passions, it is seldom it can entirely remove them. How few criminals are there, who have no ill-will to the person, that accuses them, or to the judge, that condemns them, even though they be conscious of their own deserts? In like manner our antagonist in a law-suit, and our competitor for any office, are commonly regarded as our enemies; though we must acknowledge, if we would but reflect a moment, that their motive is entirely as justifiable as our own.
Besides we may consider, that when we receive harm from any person, we are apt to imagine him criminal, and it is with extreme difficulty we allow of his justice and innocence. This is a clear proof, that, independent of the opinion of iniquity, any harm or uneasiness has a natural tendency to excite our hatred, and that afterwards we seek for reasons upon which we may justify and establish the passion. Here the idea of injury produces not the passion, but arises from it.
Nor is it any wonder that passion should produce the opinion of injury; since otherwise it must suffer a considerable diminution, which all the passions avoid as much as possible. The removal of injury may remove the anger, without proving that the anger arises only from the injury. The harm and the justice are two contrary objects, of which the one has a tendency to produce hatred, and the other love; and it is according to their different degrees, and our particular turn of thinking, that either of the objects prevails, and excites its proper passion.
SECT. IV OF THE LOVE OF RELATIONS Having given a reason, why several actions, that cause a real pleasure or uneasiness, excite not any degree, or but a small one, of the passion of love or hatred towards the actors; it will be necessary to shew, wherein consists the pleasure or uneasiness of many objects, which we find by experience to produce these passions.
According to the preceding system there is always required a double relation of impressions and ideas betwixt the cause and effect, in order to produce either love or hatred. But though this be universally true, it is remarkable that the passion of love may be excited by only one relation of a different kind, viz, betwixt ourselves and the object; or more properly speaking, that this relation is always attended with both the others. Whoever is united to us by any connexion is always sure of a share of our love, proportioned to the connexion, without enquiring into his other qualities. Thus the relation of blood produces the strongest tie the mind is capable of in the love of parents to their children, and a lesser degree of the same affection, as the relation lessens. Nor has consanguinity alone this effect, but any other relation without exception. We love our country-men, our neighbours, those of the same trade, profession, and even name with ourselves. Every one of these relations is esteemed some tie, and gives a title to a share of our affection.
There is another phænomenon, which is parallel to this, viz, that acquaintance, without any kind of relation, gives rise to love and kindness. When we have contracted a habitude and intimacy with any person; though in frequenting his company we have not been able to discover any very valuable quality, of which he is possessed; yet we cannot forebear preferring him to strangers, of whose superior merit we are fully convinced. These two phaenomena of the effects of relation and acquaintance will give mutual light to each other, and may be both explained from the same principle.
Those, who take a pleasure in declaiming against human nature, have observed, that man is altogether insufficient to support himself; and that when you loosen all the holds, which he has of external objects, he immediately drops down into the deepest melancholy and despair.
From this, say they, proceeds that continual search after amusement in gaming, in hunting, in business; by which we endeavour to forget ourselves, and excite our spirits from the languid state, into which they fall, when not sustained by some brisk and lively emotion. To this method of thinking I so far agree, that I own the mind to be insufficient, of itself, to its own entertainment, and that it naturally seeks after foreign objects, which may produce a lively sensation, and agitate the spirits. On the appearance of such an object it awakes, as it were, from a dream: The blood flows with a new tide: The heart is elevated: And the whole man acquires a vigour, which he cannot command in his solitary and calm moments. Hence company is naturally so rejoicing, as presenting the liveliest of all objects, viz, a rational and thinking Being like ourselves, who communicates to us all the actions of his mind; makes us privy to his inmost sentiments and affections; and lets us see, in the very instant of their production, all the emotions, which are caused by any object. Every lively idea is agreeable, but especially that of a passion, because such an idea becomes a kind of passion, and gives a more sensible agitation to the mind, than any other image or conception.
This being once admitted, all the rest is easy. For as the company of strangers is agreeable to us for a short time, by inlivening our thought; so the company of our relations and acquaintance must be peculiarly agreeable, because it has this effect in a greater degree, and is of more durable influence. Whatever is related to us is conceived in a lively manner by the easy transition from ourselves to the related object. Custom also, or acquaintance facilitates the entrance, and strengthens the conception of any object. The first case is parallel to our reasonings from cause and effect; the second to education. And as reasoning and education concur only in producing a lively and strong idea of any object; so is this the only particular, which is common to relation and acquaintance. This must, therefore, be the influencing quality, by which they produce all their common effects; and love or kindness being one of these effects, it must be from the force and liveliness of conception, that the passion is derived. Such a conception is peculiarly agreeable, and makes us have an affectionate regard for every thing, that produces it, when the proper object of kindness and goodwill.
It is obvious, that people associate together according to their particular tempers and dispositions, and that men of gay tempers naturally love the gay; as the serious bear an affection to the serious.
This not only happens, where they remark this resemblance betwixt themselves and others, but also by the natural course of the disposition, and by a certain sympathy, which always arises betwixt similar characters. Where they remark the resemblance, it operates after the manner of a relation, by producing a connexion of ideas. Where they do not remark it, it operates by some other principle; and if this latter principle be similar to the former, it must be received as a confirmation of the foregoing reasoning.
The idea of ourselves is always intimately present to us, and conveys a sensible degree of vivacity to the idea of any other object, to which we are related. This lively idea changes by degrees into a real impression; these two kinds of perception being in a great measure the same, and differing only in their degrees of force and vivacity. But this change must be produced with the greater ease, that our natural temper gives us a propensity to the same impression, which we observe in others, and makes it arise upon any slight occasion. In that case resemblance converts the idea into an impression, not only by means of the relation, and by transfusing the original vivacity into the related idea; but also by presenting such materials as take fire from the least spark. And as in both cases a love or affection arises from the resemblance, we may learn that a sympathy with others is agreeable only by giving an emotion to the spirits, since an easy sympathy and correspondent emotions are alone common to RELATION, ACQUAINTANCE, and RESEMBLANCE.
The great propensity men have to pride may be considered as another similar phænomenon. It often happens, that after we have lived a considerable time in any city; however at first it might be disagreeable to us; yet as we become familiar with the objects, and contact an acquaintance, though merely with the streets and buildings, the aversion diminishes by degrees, and at last changes into the opposite passion.
The mind finds a satisfaction and ease in the view of objects, to which it is accustomed, and naturally prefers them to others, which, though, perhaps, in themselves more valuable, are less known to it. By the same quality of the mind we are seduced into a good opinion of ourselves, and of all objects, that belong to us. They appear in a stronger light; are more agreeable; and consequently fitter subjects of pride and vanity, than any other.
It may not be amiss, in treating of the affection we bear our acquaintance and relations, to observe some pretty curious phaenomena, which attend it. It is easy to remark in common life, that children esteem their relation to their mother to be weakened, in a great measure, by her second marriage, and no longer regard her with the same eye, as if she had continued in her state of widow-hood. Nor does this happen only, when they have felt any inconveniences from her second marriage, or when her husband is much her inferior; but even without any of these considerations, and merely because she has become part of another family. This also takes place with regard to the second marriage of a father; but in a much less degree: And it is certain the ties of blood are not so much loosened in the latter case as by the marriage of a mother. These two phaenomena are remarkable in themselves, but much more so when compared.
In order to produce a perfect relation betwixt two objects, it is requisite, not only that the imagination be conveyed from one to the other by resemblance, contiguity or causation, but also that it return back from the second to the first with the same ease and facility. At first sight this may seem a necessary and unavoidable consequence. If one object resemble another, the latter object must necessarily resemble the former. If one object be the cause of another, the second object is effect to its cause. It is the same case with contiguity: And therefore the relation being always reciprocal, it may be thought, that the return of the imagination from the second to the first must also, in every case, be equally natural as its passage from the first to the second.
But upon farther examination we shall easily discover our mistake.
For supposing the second object, beside its reciprocal relation to the first, to have also a strong relation to a third object; in that case the thought, passing from the first object to the second, returns not back with the same facility, though the relation continues the same; but is readily carryed on to the third object, by means of the new relation, which presents itself, and gives a new impulse to the imagination. This new relation, therefore, weakens the tie betwixt the first and second objects. The fancy is by its very nature wavering and inconstant; and considers always two objects as more strongly related together, where it finds the passage equally easy both in going and returning, than where the transition is easy only in one of these motions. The double motion is a kind of a double tie, and binds the objects together in the closest and most intimate manner.
The second marriage of a mother breaks not the relation of child and parent; and that relation suffices to convey my imagination from myself to her with the greatest ease and facility. But after the imagination is arrived at this point of view, it finds its object to be surrounded with so many other relations, which challenge its regard, that it knows not which to prefer, and is at a loss what new object to pitch upon. The ties of interest and duty bind her to another family, and prevent that return of the fancy from her to myself, which is necessary to support the union. The thought has no longer the vibration, requisite to set it perfectly at ease, and indulge its inclination to change. It goes with facility, but returns with difficulty; and by that interruption finds the relation much weakened from what it would be were the passage open and easy on both sides.
Now to give a reason, why this effect follows not in the same degree upon the second marriage of a father: we may reflect on what has been proved already, that though the imagination goes easily from the view of a lesser object to that of a greater, yet it returns not with the same facility from the greater to the less. When my imagination goes from myself to my father, it passes not so readily from him to his second wife, nor considers him as entering into a different family, but as continuing the head of that family, of which I am myself a part. His superiority prevents the easy transition of the thought from him to his spouse, but keeps the passage still open for a return to myself along the same relation of child and parent. He is not sunk in the new relation he acquires; so that the double motion or vibration of thought is still easy and natural. By this indulgence of the fancy in its inconstancy, the tie of child and parent still preserves its full force and influence. A mother thinks not her tie to a son weakened, because it is shared with her husband: Nor a son his with a parent, because it is shared with a brother. The third object is here related to the first, as well as to the second; so that the imagination goes and comes along all of them with the greatest facility.
SECT. V OF OUR ESTEEM FOR THE RICH AND POWERFUL Nothing has a greater tendency to give us an esteem for any person, than his power and riches; or a contempt, than his poverty and meanness: And as esteem and contempt are to be considered as species of love and hatred, it will be proper in this place to explain these phaenomena.
Here it happens most fortunately, that the greatest difficulty is not to discover a principle capable of producing such an effect, but to choose the chief and predominant among several, that present themselves. The satisfaction we take in the riches of others, and the esteem we have for the possessors may be ascribed to three different causes. FIRST, To the objects they possess; such as houses, gardens, equipages; which, being agreeable in themselves, necessarily produce a sentiment of pleasure in every one; that either considers or surveys them. SECONDLY, To the expectation of advantage from the rich and powerful by our sharing their possessions. THIRDLY, To sympathy, which makes us partake of the satisfaction of every one, that approaches us. All these principles may concur in producing the present phænomenon. The question is, to which of them we ought principally to ascribe it.
It is certain, that the first principle, viz, the reflection on agreeable objects, has a greater influence, than what, at first sight, we may be apt to imagine. We seldom reflect on what is beautiful or ugly, agreeable or disagreeable, without an emotion of pleasure or uneasiness; and though these sensations appear not much in our common indolent way of thinking, it is easy, either in reading or conversation, to discover them. Men of wit always turn the discourse on subjects that are entertaining to the imagination; and poets never present any objects but such as are of the same nature. Mr Philips has chosen CYDER for the subject of an excellent poem. Beer would not have been so proper, as being neither so agreeable to the taste nor eye. But he would certainly have preferred wine to either of them, could his native country have afforded him so agreeable a liquor. We may learn from thence, that every thing, which is agreeable to the senses, is also in some measure agreeable to the fancy, and conveys to the thought an image of that satisfaction, which it gives by its real application to the bodily organs.
But though these reasons may induce us to comprehend this delicacy of the imagination among the causes of the respect, which we pay the rich and powerful, there are many other reasons, that may keep us from regarding it as the sole or principal. For as the ideas of pleasure can have an influence only by means of their vivacity, which makes them approach impressions, it is most natural those ideas should have that influence, which are favoured by most circumstances, and have a natural tendency to become strong and lively; such as our ideas of the passions and sensations of any human creature. Every human creature resembles ourselves, and by that means has an advantage above any other object, in operating on the imagination.
Besides, if we consider the nature of that faculty, and the great influence which all relations have upon it, we shall easily be persuaded, that however the ideas of the pleasant wines, music, or gardens, which the rich man enjoys, may become lively and agreeable, the fancy will not confine itself to them, but will carry its view to the related objects; and in particular, to the person, who possesses them.
And this is the more natural, that the pleasant idea or image produces here a passion towards the person, by means of his relation to the object; so that it is unavoidable but he must enter into the original conception, since he makes the object of the derivative passion: But if he enters into the original conception, and is considered as enjoying these agreeable objects, it is sympathy, which is properly the cause of the affection; and the third principle is more powerful and universal than the first.
Add to this, that riches and power alone, even though unemployed, naturally cause esteem and respect: And consequently these passions arise not from the idea of any beautiful or agreeable objects. It is true; money implies a kind of representation of such objects, by the power it affords of obtaining them; and for that reason may still be esteemed proper to convey those agreeable images, which may give rise to the passion. But as this prospect is very distant, it is more natural for us to take a contiguous object, viz, the satisfaction, which this power affords the person, who is possest of it. And of this we shall be farther satisfyed, if we consider, that riches represent the goods of life, only by means of the will; which employs them; and therefore imply in their very nature an idea of the person, and cannot be considered without a kind of sympathy with his sensations and enjoyments.
This we may confirm by a reflection, which to some will, perhaps, appear too subtile and refined. I have already observed, that power, as distinguished from its exercise, has either no meaning at all, or is nothing but a possibility or probability of existence; by which any object approaches to reality, and has a sensible influence on the mind.
I have also observed, that this approach, by an illusion of the fancy, appears much greater, when we ourselves are possest of the power, than when it is enjoyed by another; and that in the former case the objects seem to touch upon the very verge of reality, and convey almost an equal satisfaction, as if actually in our possession. Now I assert, that where we esteem a person upon account of his riches, we must enter into this sentiment of the proprietor, and that without such a sympathy the idea of the agreeable objects, which they give him the power to produce, would have but a feeble influence upon us. An avaricious man is respected for his money, though he scarce is possest of a power; that is, there scarce is a probability or even possibility of his employing it in the acquisition of the pleasures and conveniences of life. To himself alone this power seems perfect and entire; and therefore we must receive his sentiments by sympathy, before we can have a strong intense idea of these enjoyments, or esteem him upon account of them.
Thus we have found, that the first principle, viz, the agreeable idea of those objects, which riches afford the enjoyment of; resolves itself in a great measure into the third, and becomes a sympathy with the person we esteem or love. Let us now examine the second principle, viz, the agreeable expectation of advantage, and see what force we may justly attribute to it.
It is obvious, that though riches and authority undoubtedly give their owner a power of doing us service, yet this power is not to be considered as on the same footing with that, which they afford him, of pleasing himself, and satisfying his own appetites. Self-love approaches the power and exercise very near each other in the latter case; but in order to produce a similar effect in the former, we must suppose a friendship and good-will to be conjoined with the riches. Without that circumstance it is difficult to conceive on what we can found our hope of advantage from the riches of others, though there is nothing more certain, than that we naturally esteem and respect the rich, even before we discover in them any such favourable disposition towards us.
But I carry this farther, and observe, not only that we respect the rich and powerful, where they shew no inclination to serve us, but also when we lie so much out of the sphere of their activity, that they cannot even be supposed to be endowed with that power. Prisoners of war are always treated with a respect suitable to their condition; and it is certain riches go very far towards fixing the condition of any person.
If birth and quality enter for a share, this still affords us an argument of the same kind. For what is it we call a man of birth, but one who is descended from a long succession of rich and powerful ancestors, and who acquires our esteem by his relation to persons whom we esteem? His ancestors, therefore, though dead, are respected, in some measure, on account of their riches, and consequently without any kind of expectation.
But not to go so far as prisoners of war and the dead to find instances of this disinterested esteem for riches, let us observe with a little attention those phaenomena that occur to us in common life and conversation. A man, who is himself of a competent fortune, upon coming into a company of strangers, naturally treats them with different degrees of respect and deference, as he is informed of their different fortunes and conditions; though it is impossible he can ever propose, and perhaps would not accept of any advantage from them. A traveller is always admitted into company, and meets with civility, in proportion as his train and equipage speak him a man of great or moderate fortune. In short, the different ranks of men are, in a great measure, regulated by riches, and that with regard to superiors as well as inferiors, strangers as well as acquaintance.
There is, indeed, an answer to these arguments, drawn from the influence of general rules. It may be pretended, that being accustomed to expect succour and protection from the rich and powerful, and to esteem them upon that account, we extend the same sentiments to those, who resemble them in their fortune, but from whom we can never hope for any advantage. The general rule still prevails, and by giving a bent to the imagination draws along the passion, in the same manner as if its proper object were real and existent.
But that this principle does not here take place, will easily appear, if we consider, that in order to establish a general rule, and extend it beyond its proper bounds, there is required a certain uniformity in our experience, and a great superiority of those instances, which are conformable to the rule, above the contrary. But here the case is quite otherwise. Of a hundred men of credit and fortune I meet with, there is not, perhaps, one from whom I can expect advantage; so that it is impossible any custom can ever prevail in the present case.
Upon the whole, there remains nothing, which can give us an esteem for power and riches, and a contempt for meanness and poverty, except the principle of sympathy, by which we enter into the sentiments of the rich and poor, and partake of their pleasure and uneasiness. Riches give satisfaction to their possessor; and this satisfaction is conveyed to the beholder by the imagination, which produces an idea resembling the original impression in force and vivacity. This agreeable idea or impression is connected with love, which is an agreeable passion. It proceeds from a thinking conscious being, which is the very object of love. From this relation of impressions, and identity of ideas, the passion arises, according to my hypothesis.
The best method of reconciling us to this opinion is to take a general survey of the universe, and observe the force of sympathy through the whole animal creation, and the easy communication of sentiments from one thinking being to another. In all creatures, that prey not upon others, and are not agitated with violent passions, there appears a remarkable desire of company, which associates them together, without any advantages they can ever propose to reap from their union. This is still more conspicuous in man, as being the creature of the universe, who has the most ardent desire of society, and is fitted for it by the most advantages. We can form no wish, which has not a reference to society.
A perfect solitude is, perhaps, the greatest punishment we can suffer.
Every pleasure languishes when enjoyed a-part from company, and every pain becomes more cruel and intolerable. Whatever other passions we may be actuated by; pride, ambition, avarice, curiosity, revenge or lust; the soul or animating principle of them all is sympathy; nor would they have any force, were we to abstract entirely from the thoughts and sentiments of others. Let all the powers and elements of nature conspire to serve and obey one man: Let the sun rise and set at his command: The sea and rivers roll as he pleases, and the earth furnish spontaneously whatever may be useful or agreeable to him: He will still be miserable, till you give him some one person at least, with whom he may share his happiness, and whose esteem and friendship he may enjoy.
This conclusion from a general view of human nature, we may confirm by particular instances, wherein the force of sympathy is very remarkable.
Most kinds of beauty are derived from this origin; and though our first object be some senseless inanimate piece of matter, it is seldom we rest there, and carry not our view to its influence on sensible and rational creatures. A man, who shews us any house or building, takes particular care among other things to point out the convenience of the apartments, the advantages of their situation, and the little room lost in the stairs, antichambers and passages; and indeed it is evident, the chief part of the beauty consists in these particulars. The observation of convenience gives pleasure, since convenience is a beauty. But after what manner does it give pleasure? It is certain our own interest is not in the least concerned; and as this is a beauty of interest, not of form, so to speak, it must delight us merely by communication, and by our sympathizing with the proprietor of the lodging. We enter into his interest by the force of imagination, and feel the same satisfaction, that the objects naturally occasion in him.
This observation extends to tables, chairs, scritoires, chimneys, coaches, sadles, ploughs, and indeed to every work of art; it being an universal rule, that their beauty is chiefly derived from their utility, and from their fitness for that purpose, to which they are destined.
But this is an advantage, that concerns only the owner, nor is there any thing but sympathy, which can interest the spectator.
It is evident, that nothing renders a field more agreeable than its fertility, and that scarce any advantages of ornament or situation will be able to equal this beauty. It is the same case with particular trees and plants, as with the field on which they grow. I know not but a plain, overgrown with furze and broom, may be, in itself, as beautiful as a hill covered with vines or olive-trees; though it will never appear so to one, who is acquainted with the value of each. But this is a beauty merely of imagination, and has no foundation in what appears to the senses. Fertility and value have a plain reference to use; and that to riches, joy, and plenty; in which though we have no hope of partaking, yet we enter into them by the vivacity of the fancy, and share them, in some measure, with the proprietor.
There is no rule in painting more reasonable than that of ballancing the figures, and placing them with the greatest exactness on their proper centers of gravity. A figure, which is not justly ballanced, is disagreeable; and that because it conveys the ideas of its fall, of harm, and of pain: Which ideas are painful, when by sympathy they acquire any degree of force and vivacity.
Add to this, that the principal part of personal beauty is an air of health and vigour, and such a construction of members as promises strength and activity. This idea of beauty cannot be accounted for but by sympathy.
In general we may remark, that the minds of men are mirrors to one another, not only because they reflect each others emotions, but also because those rays of passions, sentiments and opinions may be often reverberated, and may decay away by insensible degrees. Thus the pleasure, which a rich man receives from his possessions, being thrown upon the beholder, causes a pleasure and esteem; which sentiments again, being perceived and sympathized with, encrease the pleasure of the possessor; and being once more reflected, become a new foundation for pleasure and esteem in the beholder. There is certainly an original satisfaction in riches derived from that power, which they bestow, of enjoying all the pleasures of life; and as this is their very nature and essence, it must be the first source of all the passions, which arise from them. One of the most considerable of these passions is that of love or esteem in others, which therefore proceeds from a sympathy with the pleasure of the possessor. But the possessor has also a secondary satisfaction in riches arising from the love and esteem he acquires by them, and this satisfaction is nothing but a second reflexion of that original pleasure, which proceeded from himself. This secondary satisfaction or vanity becomes one of the principal recommendations of riches, and is the chief reason, why we either desire them for ourselves, or esteem them in others. Here then is a third rebound of the original pleasure; after which it is difficult to distinguish the images and reflexions, by reason of their faintness and confusion.
SECT. VI OF BENEVOLENCE AND ANGER Ideas may be compared to the extension and solidity of matter, and impressions, especially reflective ones, to colours, tastes, smells and other sensible qualities. Ideas never admit of a total union, but are endowed with a kind of impenetrability, by which they exclude each other, and are capable of forming a compound by their conjunction, not by their mixture. On the other hand, impressions and passions are susceptible of an entire union; and like colours, may be blended so perfectly together, that each of them may lose itself, and contribute only to vary that uniform impression, which arises from the whole. Some of the most curious phaenomena of the human mind are derived from this property of the passions.
In examining those ingredients, which are capable of uniting with love and hatred, I begin to be sensible, in some measure, of a misfortune, that has attended every system of philosophy, with which the world has been yet acquainted. It is commonly found, that in accounting for the operations of nature by any particular hypothesis; among a number of experiments, that quadrate exactly with the principles we would endeavour to establish; there is always some phænomenon, which is more stubborn, and will not so easily bend to our purpose. We need not be surprized, that this should happen in natural philosophy. The essence and composition of external bodies are so obscure, that we must necessarily, in our reasonings, or rather conjectures concerning them, involve ourselves in contradictions and absurdities. But as the perceptions of the mind are perfectly known, and I have used all imaginable caution in forming conclusions concerning them, I have always hoped to keep clear of those contradictions, which have attended every other system. Accordingly the difficulty, which I have at present in my eye, is nowise contrary to my system; but only departs a little from
