<p xml:id="par3"><hi rend="dropCap">A</hi>T our next meeting there was a great <lb xml:id="l2"/>deal of good company, who came to <lb xml:id="l3"/>hear the <hi rend="italic">Boys Philosophy</hi>, as they called it; <lb xml:id="l4"/>on which account I could observe that Master <lb xml:id="l5"/><hi rend="italic">Telescope</hi> took less pains to be understood by <lb xml:id="l6"/>the young Gentlemen and Ladies, and ad<lb type="hyphenated" xml:id="l7"/>dressed himself more particularly to those of <lb xml:id="l8"/>greater abilities.</p>
<p rend="indent5" xml:id="par4">As the company came in laughing, and af<lb type="hyphenated" xml:id="l9"/>fected to talk, and behaved in a supercilious <lb xml:id="l10"/>manner, which even some great personages <lb xml:id="l11"/>do in these our days of refinement, he stood <lb xml:id="l12"/>silent, till my Lord Marquis desired him to <lb xml:id="l13"/>open the Lecture; upon which he bowed, <lb xml:id="l14"/>to his Lordship and the rest of the company <lb xml:id="l15"/>and began; but had scarcely spoke three <lb xml:id="l16"/>words before he was interrupted by Sir <lb xml:id="l17"/><hi rend="italic">Harry</hi>; he therefore stopt for some time, <lb xml:id="l18"/>and then began again; but the tongue of <lb xml:id="l19"/>the young Baronet soon silenced him, and he <lb xml:id="l20"/>stood, without speaking, a considerable time. <lb xml:id="l21"/>On this the company looked at each other, <lb xml:id="l22"/><fw type="catch" place="bottomRight">and</fw><pb xml:id="p99" n="99"/><fw type="pag" place="topCenter">[ 99 ]</fw><fw type="sig" place="bottomCenter">K 2</fw>and the Marquis bad him go on. My Dear, <lb xml:id="l23"/>says the Marchioness, how can you expect <lb xml:id="l24"/>this young Gentleman to read a long Lec<lb type="hyphenated" xml:id="l25"/>ture, when you know that Sir <hi rend="italic">Harry</hi>, who <lb xml:id="l26"/>loves to hear himself talk of all things, has <lb xml:id="l27"/>not patience to support so much taciturnity! <lb xml:id="l28"/>Why, Madam, says the Ambassador of <hi rend="italic">Ban<lb xml:id="l29"/>tam</hi> (who came in with the Marquis) I <lb xml:id="l30"/>thought we had all been assembled to hear <lb xml:id="l31"/>this Lecture. That was indeed the inten<lb type="hyphenated" xml:id="l32"/>tion of our meeting, says the Marchioness; <lb xml:id="l33"/>but I hope your Excellency knows the polite <lb xml:id="l34"/>world better, than to expect people should be <lb xml:id="l35"/>so old fashioned as to behave, on these occa<lb type="hyphenated" xml:id="l36"/>sions, with any sort of good-manners or de<lb type="hyphenated" xml:id="l37"/>corum. In my country, says the Ambassa<lb type="hyphenated" xml:id="l38"/>dor, all the company keep a profound si<lb type="hyphenated" xml:id="l39"/>lence at these meetings. It may be so, re<lb type="hyphenated" xml:id="l40"/>plied the Marchioness; but I assure your <lb xml:id="l41"/>Excellency, it is not the custom here. Why, <lb xml:id="l42"/>Sir, I have been often interrupted in the <lb xml:id="l43"/>middle of a fine air, at an Oratorio, by a <lb xml:id="l44"/>Gentleman's whistling an Hornpipe; and at <lb xml:id="l45"/>the Rehearsal at St. <hi rend="italic">Paul</hi>'s, it is no uncom<lb type="hyphenated" xml:id="l46"/>mon thing to hear both Gentlemen and La<lb type="hyphenated" xml:id="l47"/>dies laugh louder than the organ. Hush, <lb xml:id="l48"/>Madam, says the Marquis, if your friends <lb xml:id="l49"/>and neighbours are fools, you ought not to <lb xml:id="l50"/>expose them, and especially to foreigners. <lb xml:id="l51"/><fw type="catch" place="bottomRight">Take</fw><pb xml:id="p100" n="100"/><fw type="pag" place="topCenter">[ 100 ]</fw>Take care, while you condemn this unpolite <lb xml:id="l52"/>behaviour in others, that you don't run into <lb xml:id="l53"/>it yourself. <hi rend="italic">Politeness</hi> is the art of being <lb xml:id="l54"/>always agreeable in company; it can there<lb type="hyphenated" xml:id="l55"/>fore seldom deal in <hi rend="italic">sarcasm</hi> or <hi rend="italic">irony</hi>; be<lb type="hyphenated" xml:id="l56"/>cause it should never do any thing to abridge <lb xml:id="l57"/>the happiness of others; and you see, my <lb xml:id="l58"/>Dear, you have made Sir <hi rend="italic">Harry</hi> uneasy, for <lb xml:id="l59"/>he blushes. The company laughed at Sir <lb xml:id="l60"/><hi rend="italic">Harry</hi>, who joined them, and being deter<lb type="hyphenated" xml:id="l61"/>mined to hold his tongue, our Philosopher <lb xml:id="l62"/>thus proceeded.</p>
<p rend="indent5" xml:id="par5">After the cursory view of Nature, which <lb xml:id="l63"/>was concluded in my last Lecture, it may <lb xml:id="l64"/>not be amiss to examine our own faculties, <lb xml:id="l65"/>and see by what means we acquire and trea<lb type="hyphenated" xml:id="l66"/>sure up a knowledge of these things; and <lb xml:id="l67"/>this is done, I apprehend, by means of <lb xml:id="l68"/>the <hi rend="italic">senses</hi>, the operations of the <hi rend="italic">mind</hi>, and the <lb xml:id="l69"/><hi rend="italic">memory</hi>, which last may be called the Store<lb type="hyphenated" xml:id="l70"/>house of the <hi rend="italic">understanding</hi>. The first time <lb xml:id="l71"/>little Master is brought to a looking-glass, <lb xml:id="l72"/>he thinks he has found a new play-mate, and <lb xml:id="l73"/>calls out <hi rend="italic">Little boy! little boy!</hi> for having <lb xml:id="l74"/>never seen his own face before, it is no won<lb type="hyphenated" xml:id="l75"/>der that he should not know it. Here is the <lb xml:id="l76"/>idea, therefore, of something new acquired <lb xml:id="l77"/>by <hi rend="italic">sight</hi>.--Presently the father, and mother, <lb xml:id="l78"/>and nurse come forward to partake of the <lb xml:id="l79"/><fw type="catch" place="bottomRight">child's</fw><pb xml:id="p101" n="101"/><fw type="pag" place="topCenter">[ 101 ]</fw><fw type="sig" place="bottomCenter">K 3</fw>child's diversion. Upon seeing these figures <lb xml:id="l80"/>in the glass with whom he is so well acquaint<lb type="hyphenated" xml:id="l81"/>ed, he immediately calls out, <hi rend="italic">There, Papa! <lb xml:id="l82"/>there, Mamma! there. Nurse!</hi> And now the <lb xml:id="l83"/><hi rend="italic">mind</hi> begins to operate; for feeling his fa<lb type="hyphenated" xml:id="l84"/>ther's hand on his own head, and seeing it <lb xml:id="l85"/>on the little boy's head in the glass, he cries, <lb xml:id="l86"/><hi rend="italic">There me!</hi> --Now this transaction is lodged <lb xml:id="l87"/>in the <hi rend="italic">memory</hi>, which, whenever a looking-<lb xml:id="l88"/>glass is mentioned, will give back to the <lb xml:id="l89"/>mind this idea of its reflecting objects.</p>
<p rend="indent5" xml:id="par6">The whole company were pleased with <lb xml:id="l90"/>this familiar demonstration; but Sir <hi rend="italic">Harry</hi> <lb xml:id="l91"/>asked how he came, of all things, to make <lb xml:id="l92"/>use of a looking-glass? Because, Sir, says <lb xml:id="l93"/>he, it is an object with which some people <lb xml:id="l94"/>are the most intimately acquainted.--As Sir <lb xml:id="l95"/><hi rend="italic">Harry</hi> is an egregious fop, this reply pro<lb type="hyphenated" xml:id="l96"/>duced a loud laugh, and Master <hi rend="italic">Telescope</hi> <lb xml:id="l97"/>was looked upon to be a <hi rend="italic">Wit</hi> as well as a <lb xml:id="l98"/><hi rend="italic">Philosopher</hi>; however, I am inclined to <lb xml:id="l99"/>think the expression was accidental, and not <lb xml:id="l100"/>intended to hit Sir <hi rend="italic">Harry</hi>, because I know <lb xml:id="l101"/>his good sense would not permit him to treat <lb xml:id="l102"/>an elder and superior in that manner.--The <lb xml:id="l103"/>laugh being a little subsided, our Philosopher <lb xml:id="l104"/>thus proceeded on his Lecture.</p>
<p rend="indent5" xml:id="par7">All our ideas, therefore, are obtained ei<lb type="hyphenated" xml:id="l105"/>ther by <hi rend="italic">sensation</hi> or <hi rend="italic">reflection</hi>, that is to say, <lb xml:id="l106"/><fw type="catch" place="bottomRight">by</fw><pb xml:id="p102" n="102"/><fw type="pag" place="topCenter">[ 102 ]</fw>by means of our five senses, as <hi rend="italic">seeing, hear<lb type="hyphenated" xml:id="l107"/>ing, smelling, tasting,</hi> and <hi rend="italic">touching</hi>, or by the <lb xml:id="l108"/><hi rend="italic">operations of the mind</hi>.</p>
<p rend="indent5" xml:id="par8">Before you proceed further, says the Coun<lb type="hyphenated" xml:id="l109"/>tess of <hi rend="italic">Twylight</hi>, you should, I think, ex<lb type="hyphenated" xml:id="l110"/>plain to the company what is meant by the <lb xml:id="l111"/>term <hi rend="italic">idea</hi>. That, I apprehend, is suffi<lb type="hyphenated" xml:id="l112"/>ciently explained by what was said about the <lb xml:id="l113"/>looking-glass, says the Philosopher; but if <lb xml:id="l114"/>your Ladyship requires another definition <lb xml:id="l115"/>you shall have it. By an <hi rend="italic">idea</hi>, then, I <lb xml:id="l116"/>mean that <hi rend="italic">image</hi> or <hi rend="italic">picture</hi>, Madam, which <lb xml:id="l117"/>is formed in the <hi rend="italic">mind</hi>, of any thing which we <lb xml:id="l118"/>have <hi rend="italic">seen</hi>, or even <hi rend="italic">heard talk of</hi>; for the <lb xml:id="l119"/>mind is so adroit and ready at this kind of <lb xml:id="l120"/><hi rend="italic">painting</hi>, that a town, for instance, is no <lb xml:id="l121"/>sooner mentioned, but the <hi rend="italic">imagination</hi> shapes <lb xml:id="l122"/>it into form and presents it to the <hi rend="italic">memory</hi>. <lb xml:id="l123"/>None of this company, I presume, have ever <lb xml:id="l124"/>seen <hi rend="italic">Dresden</hi>, yet there is not one, perhaps, <lb xml:id="l125"/>but has formed, or conceived in his mind, <lb xml:id="l126"/>some <hi rend="italic">idea</hi> or <hi rend="italic">picture</hi> of that unhappy place. <lb xml:id="l127"/>Not one of us ever saw <hi rend="italic">N<unclear reason="copy" cert="low">abob</unclear></hi>'s prodi<lb type="hyphenated" xml:id="l128"/>gious army and elephants, yet we have all <lb xml:id="l129"/>formed to ourselves a <hi rend="italic">picture</hi> of their running <lb xml:id="l130"/>away from a small party of our brave country<lb type="hyphenated" xml:id="l131"/>men, led against them by the gallant and cou<lb type="hyphenated" xml:id="l132"/>rageous Colonel <hi rend="italic">Clive</hi>. When we read in the <lb xml:id="l133"/>news-papers a description of a <hi rend="italic">sea-engage</hi><lb type="hyphenated" xml:id="l134"/><fw type="catch" place="bottomRight"><hi rend="italic">ment</hi></fw><pb xml:id="p103" n="103"/><fw type="pag" place="topCenter">[ 103 ]</fw><hi rend="italic">ment</hi>, or the taking of <hi rend="italic">Louisburg, Quebec,</hi> or <lb xml:id="l135"/>any other important fortress, the mind <lb xml:id="l136"/>immediately gives us a <hi rend="italic">picture</hi> of the <hi rend="italic">trans<lb type="hyphenated" xml:id="l137"/>action</hi>, and we see our valient officers issuing <lb xml:id="l138"/>their orders, and their intrepid men <unclear reason="copy" cert="medium">furlin</unclear>g <lb xml:id="l139"/>their sails, firing their guns, scaling the walls, <lb xml:id="l140"/>and driving their foes before them. To pur<lb type="hyphenated" xml:id="l141"/>sue this subject a little farther--No man has <lb xml:id="l142"/>ever seen a <hi rend="italic">dragon</hi>, a <hi rend="italic">griffin</hi>, or a <hi rend="italic">fairy</hi>; yet <lb xml:id="l143"/>every one has formed in his mind a <hi rend="italic">picture, <lb xml:id="l144"/>image</hi>, or, in other words, an <hi rend="italic">idea</hi> of these <lb xml:id="l145"/>imaginary beings--Now when this <hi rend="italic">idea</hi> or <lb xml:id="l146"/><hi rend="italic">image</hi> is formed in the mind from a view of <lb xml:id="l147"/>the object itself, it may be called an <hi rend="italic">ade<lb type="hyphenated" xml:id="l148"/>quate</hi> or <hi rend="italic">real idea</hi>; but when it is conceived <lb xml:id="l149"/>in the mind without seeing the object, it is <lb xml:id="l150"/>an <hi rend="italic">inadequate</hi> or <hi rend="italic">imaginary idea</hi>.</p>
<p rend="indent5" xml:id="par9">I shall begin my discourse of the Senses <lb xml:id="l151"/>with that of the <hi rend="smallCaps">Sight</hi>, says he, because, <lb xml:id="l152"/>as Mr. <hi rend="italic">Addison</hi> observes, the sight is the <lb xml:id="l153"/>most perfect and pleasing of them all. <lb xml:id="l154"/>The organ of <hi rend="italic">seeing</hi> is the <hi rend="italic">eye</hi>, which is <lb xml:id="l155"/>made up of a number of parts, and so won<lb type="hyphenated" xml:id="l156"/>derfully contrived for admitting and refract<lb type="hyphenated" xml:id="l157"/>ing the rays of light, that those which come <lb xml:id="l158"/>from the same point of the object, and fall <lb xml:id="l159"/>upon different parts of the pupil, are again <lb xml:id="l160"/>brought together at the bottom of the eye, <lb xml:id="l161"/>and by that means the whole object is <lb xml:id="l162"/><fw type="catch" place="bottomRight">painted</fw><pb xml:id="p104" n="104"/><fw type="pag" place="topCenter">[ 104 ]</fw>painted on a membrane called the <hi rend="italic">retina</hi>, <lb xml:id="l163"/>which is spread there.</p>
<p rend="indent5" xml:id="par10">But how is it possible, says Sir <hi rend="italic">Harry</hi>, for <lb xml:id="l164"/>you to know that the object is thus painted <lb xml:id="l165"/>on the <hi rend="italic">retina</hi>? In some measure from the <lb xml:id="l166"/>structure of the eye, replied the Philosopher; <lb xml:id="l167"/>but, I think, it is manifest from that disor<lb type="hyphenated" xml:id="l168"/>der of the eye which Surgeons call the <hi rend="italic">gutta <lb xml:id="l169"/>serena</hi>, the very complaint which my Lord's <lb xml:id="l170"/>Butler has in one of his eyes. If you exa<lb type="hyphenated" xml:id="l171"/>mine it you will find that he has no sight with <lb xml:id="l172"/>that eye, tho' it looks as perfect as the other <lb xml:id="l173"/>with which he sees well; this is, therefore, <lb xml:id="l174"/>occasioned by some paralytic, or other disor<lb type="hyphenated" xml:id="l175"/>der in that membrane, or expansion of the <lb xml:id="l176"/>optic nerve, which we call the <hi rend="italic">retina</hi>, and <lb xml:id="l177"/>proves that all vision arises from thence.</p>
<p rend="indent5" xml:id="par11">That which produces in us the sensation <lb xml:id="l178"/>which we call Seeing, is <hi rend="italic">light</hi>, for without <lb xml:id="l179"/><hi rend="italic">light</hi> nothing is visible. Now light may be <lb xml:id="l180"/>considered either as it radiates from luminous <lb xml:id="l181"/>bodies directly to our eyes, and thus we see <lb xml:id="l182"/>those luminous bodies themselves; as the <lb xml:id="l183"/><hi rend="italic">Sun</hi>, a lighted <hi rend="italic">torch</hi>, &amp;c. or as it is reflected <lb xml:id="l184"/>from other bodies, and thus we see a <hi rend="italic">flower</hi>, <lb xml:id="l185"/>a <hi rend="italic">man, &amp;c.</hi> or a picture reflected from them <lb xml:id="l186"/>to our eyes by the rays of light.</p>
<p rend="indent5" xml:id="par12">It is to be observed that the bodies which <lb xml:id="l187"/>respect the light are of three sorts, 1. Those <lb xml:id="l188"/><fw type="catch" place="bottomRight">that</fw><pb xml:id="p105" n="105"/><fw type="pag" place="topCenter">[ 105 ]</fw>that emit the rays of light, as the sun and <lb xml:id="l189"/>fix'd stars. 2. Those that transmit the rays <lb xml:id="l190"/>of light, as the air; and, 3. Those that re<lb type="hyphenated" xml:id="l191"/>flect them, as the Moon, the Earth, Iron,&amp;<hi rend="italic">c</hi>. <lb xml:id="l192"/>. The first we call <hi rend="italic">luminous</hi>, the second <hi rend="italic">pellu<lb type="hyphenated" xml:id="l193"/>cid</hi>, and the third, <hi rend="italic">opaque</hi> bodies. It is also <lb xml:id="l194"/>to be observed, that the rays of light them<lb type="hyphenated" xml:id="l195"/>selves are never seen; but by their means we <lb xml:id="l196"/>see the luminous bodies from which they ori<lb type="hyphenated" xml:id="l197"/>ginally came, and the opaque bodies from <lb xml:id="l198"/>which they are reflected; thus, for instance, <lb xml:id="l199"/>when the Moon shines, we cannot see the rays <lb xml:id="l200"/>which pass from the Sun to the Moon; but, by their means, we see the Moon, from <lb xml:id="l201"/>whence they are reflected.</p>
<p rend="indent5" xml:id="par13">If the eye be placed directly in the Me<lb type="hyphenated" xml:id="l202"/>dium through which the rays pass to it, the <lb xml:id="l203"/>Medium is not seen; for we never see the <lb xml:id="l204"/>air through which the rays come to our eyes. <lb xml:id="l205"/>But if a <hi rend="italic">pellucid</hi> body, thro' which the rays are <lb xml:id="l206"/>to pass, be placed at a distance from our eye, <lb xml:id="l207"/>that body will be seen, as well as those bo<lb type="hyphenated" xml:id="l208"/>dies from whence the rays came that pass <lb xml:id="l209"/>through it to our eyes: for instance, he who <lb xml:id="l210"/>looks through a pair of spectacles, not only <lb xml:id="l211"/>sees bodies through them, but also sees the <lb xml:id="l212"/>glas<unclear reason="copy">s</unclear> itself; because the glass, being a solid <lb xml:id="l213"/>body, reflects some rays of light from its <lb xml:id="l214"/>surface; and being placed at a convenient <lb xml:id="l215"/><fw type="catch" place="bottomRight">distance</fw><pb xml:id="p106" n="106"/><fw type="pag" place="topCenter">[ 106 ]</fw>distance from the eye, may be seen by those <lb xml:id="l216"/>reflected rays, at the same time that bodies, <lb xml:id="l217"/>at a greater distance, are seen by the trans<lb type="hyphenated" xml:id="l218"/>mitted rays; and this is the reason, perhaps, <lb xml:id="l219"/>why objects are seen more distinctly through <lb xml:id="l220"/>a reflecting, than through a refracting tele<lb type="hyphenated" xml:id="l221"/>scope.</p>
<p rend="indent5" xml:id="par14">There are two kinds of opaque bodies, <lb xml:id="l222"/>namely, those that are not <hi rend="italic">specular</hi>, as the <lb xml:id="l223"/><hi rend="italic">moon</hi>, the <hi rend="italic">earth</hi>, a <hi rend="italic">horse</hi>, a <hi rend="italic">man</hi>, &amp;c. and <lb xml:id="l224"/>others that are <hi rend="italic">specular</hi> or <hi rend="italic">mirrors</hi>, like those <lb xml:id="l225"/>in reflecting telescopes, whose surfaces being <lb xml:id="l226"/>polished, reflect the rays in the same order <lb xml:id="l227"/>as they came from other bodies, and shew <lb xml:id="l228"/>us their images. And rays that are thus re<lb type="hyphenated" xml:id="l229"/>flected from opaque bodies, always bring with <lb xml:id="l230"/>them to the eye the idea of colour, tho' this <lb xml:id="l231"/>colour in bodies is nothing more than a dis<lb type="hyphenated" xml:id="l232"/>position to reflect to the eye one sort of rays <lb xml:id="l233"/>more copiously or in greater plenty than an<lb type="hyphenated" xml:id="l234"/>other; for particular rays impress upon the <lb xml:id="l235"/>eye particular colours; some are <hi rend="italic">red</hi>, others <lb xml:id="l236"/><hi rend="italic">blue, yellow, green,</hi> &amp;c. Now it is to be <lb xml:id="l237"/>observed, that every, body of light which <lb xml:id="l238"/>comes from the <hi rend="italic">Sun</hi> seems to be compounded <lb xml:id="l239"/>of those various sorts of rays; and as some of <lb xml:id="l240"/>them are more <hi rend="italic">refrangible</hi> than others, that <lb xml:id="l241"/>is to say, are more turned out of their course <lb xml:id="l242"/>in passing from one medium to another, it <lb xml:id="l243"/><fw type="catch" place="bottomRight">ne<lb type="hyphenated" xml:id="l244"/></fw><pb xml:id="p107" n="107"/><fw type="pag" place="topCenter">[ 107 ]</fw>necessarily follows that they will be sepa<lb type="hyphenated" xml:id="l245"/>rated after such refraction, and their colours <lb xml:id="l246"/>appear distinct. The most <hi rend="italic">refrangible</hi> of <lb xml:id="l247"/>these are the <hi rend="italic">violet</hi>, and the least the <hi rend="italic">red</hi>; <lb xml:id="l248"/>the intermediate ones, in order, are <hi rend="italic">indigo, <lb xml:id="l249"/>blue, green, yellow,</hi> and <hi rend="italic">orange</hi>.</p>
<p rend="indent5" xml:id="par15">How do you know, Mr. Philosopher, <lb xml:id="l250"/>that colours are separated in this manner? <lb xml:id="l251"/>says Sir <hi rend="italic">Harry</hi>. I have no notion of these <lb xml:id="l252"/>doctrines without demonstration. That you <lb xml:id="l253"/>may have, if you please, replied the Philo<lb type="hyphenated" xml:id="l254"/>sopher. Pray, Master <hi rend="italic">Lovelace</hi>, hand me <lb xml:id="l255"/>that Prism.</p>

<p rend="indent5" xml:id="par16">Now, Sir <hi rend="italic">Harry</hi>, if you will please to <lb xml:id="l256"/>hold this <hi rend="italic">prism</hi> in the beams of the <hi rend="italic">Sun</hi>, you <lb xml:id="l257"/>will see the colours separated in the manner <lb xml:id="l258"/>I have mentioned. Please to look, Lady <lb xml:id="l259"/><hi rend="italic">Caroline</hi>, the separation is very pleasing, and <lb xml:id="l260"/>you will find what I said of the <hi rend="italic">rainbow</hi> in <lb xml:id="l261"/><fw type="catch" place="bottomRight">my</fw><pb xml:id="p108" n="108"/><fw type="pag" place="topCenter">[ 108 ]</fw>my third Lecture confirmed by this experi<lb type="hyphenated" xml:id="l262"/>ment.</p>
<p rend="indent5" xml:id="par17">All these rays differ not only in <hi rend="italic">refrangi<lb type="hyphenated" xml:id="l263"/>bility</hi>, but in <hi rend="italic">reflexibility</hi>; I mean in the pro<lb type="hyphenated" xml:id="l264"/>perty of being reflected some more easily <lb xml:id="l265"/>than others. And hence arise all the various <lb xml:id="l266"/>colours of bodies.</p>
<p rend="indent5" xml:id="par18">The <hi rend="italic">whiteness</hi> of the Sun's light is owing,<lb xml:id="l267"/> it is supposed, to a mixture of all the orig<lb type="hyphenated" xml:id="l268"/>inal colours in a due proportion; and <hi rend="italic">white<lb type="hyphenated" xml:id="l269"/>ness</hi> in other bodies, is a disposition to reflect <lb xml:id="l270"/>all the colours of light, nearly in the same <lb xml:id="l271"/>proportion as they are mixed in the original <lb xml:id="l272"/>rays of the Sun; as <hi rend="italic">blackness</hi>, on the con<lb type="hyphenated" xml:id="l273"/>trary, is only a disposition to absorb or stifle, <lb xml:id="l274"/>without reflection, most of the rays of every <lb xml:id="l275"/>sort that fall on those bodies; and it is for <lb xml:id="l276"/>that reason, we may suppose, that <hi rend="italic">black</hi> <lb xml:id="l277"/>clothes are warmer than those of any other <lb xml:id="l278"/>colour; and are therefore rejected by the in<lb type="hyphenated" xml:id="l279"/>habitants of hot countries, who choose such <lb xml:id="l280"/>colours for their raiment as will reflect the <lb xml:id="l281"/><hi rend="italic">Sun's</hi> rays, and not absorb them.</p>
<p rend="indent5" xml:id="par19"><hi rend="italic">Light</hi>, as we have already observed, is <lb xml:id="l282"/>successively propagated with most amazing <lb xml:id="l283"/>swiftness; for it comes from the Sun to the <lb xml:id="l284"/>Earth in about seven or eight minutes, tho' <lb xml:id="l285"/>at the distance of seventy millions of miles.</p>
<p rend="indent5" xml:id="par20"><hi rend="smallCaps">Hearing</hi> is the next most extensive of our <lb xml:id="l286"/><fw type="catch" place="bottomRight">senses,</fw><pb xml:id="p109" n="109"/><fw type="pag" place="topCenter">[ 109 ]</fw><fw type="sig" place="bottomCenter">L</fw>senses, the organ of which is the <hi rend="italic">Ear</hi>, whose <lb xml:id="l287"/>structure is extremely curious, as may be seen <lb xml:id="l288"/>in the books of Anatomy.</p>
<p rend="indent5" xml:id="par21">That which the ear conveys to the <lb xml:id="l289"/>brain is called sound, tho' till it reaches <lb xml:id="l290"/>and affects the perceptive part, it is in rea<lb type="hyphenated" xml:id="l291"/>lity nothing but motion; and this mo<lb type="hyphenated" xml:id="l292"/>tion, which produces in us the perception of <lb xml:id="l293"/>sound, is a vibration of the air, occasioned <lb xml:id="l294"/>by a very short and quick tremulous motion <lb xml:id="l295"/>of the body from whence it is propagated. <lb xml:id="l296"/>That sound is conveyed in this manner, may <lb xml:id="l297"/>be known by what is observed and felt in <lb xml:id="l298"/>the strings of musical instruments, and of <lb xml:id="l299"/>bells, which tremble or vibrate as long as <lb xml:id="l300"/>we perceive any sound come from them; <lb xml:id="l301"/>and from this effect which they produce in <lb xml:id="l302"/>us they are called Sounding Bodies.</p>
<p rend="indent5" xml:id="par22">Sound is propagated at a great rate, but <lb xml:id="l303"/>not near so fast as light. I don't know that, <lb xml:id="l304"/>says Lady <hi rend="italic">Caroline</hi>. Then your Ladyship <lb xml:id="l305"/>has forgotten what passed in our Lecture upon <lb xml:id="l306"/><hi rend="italic">Air</hi>, replied the Philosopher; and to confirm <lb xml:id="l307"/>by experiment what I advanced, I must beg <lb xml:id="l308"/>his Lordship to order one of the servants to <lb xml:id="l309"/>go to a distance into the park, and discharge a <lb xml:id="l310"/><hi rend="italic">gun</hi>. The Gentlemen were averse to this, <lb xml:id="l311"/>it being an observation they had made an <lb xml:id="l312"/><fw type="catch" place="bottomRight">hundred</fw><pb xml:id="p110" n="110"/><fw type="pag" place="topCenter">( 110 )</fw>hundred times; but to gratify the young <lb xml:id="l313"/>people, my Lord ordered his Game-keeper <lb xml:id="l314"/>out, and when the piece was discharged, <lb xml:id="l315"/>they had the satisfaction of seeing the fire <lb xml:id="l316"/>long before they heard the report.</p>
<p rend="indent5" xml:id="par23"><hi rend="smallCaps">Smelling</hi> is another sense which seems <lb xml:id="l317"/>to be excited in us by external bodies, and <lb xml:id="l318"/>sometimes by bodies at a great distance; but <lb xml:id="l319"/>that which immediately affects the nose, the <lb xml:id="l320"/>organ of smelling, and produces in us the <lb xml:id="l321"/>sensation of any smell, are effluvia or invisi<lb type="hyphenated" xml:id="l322"/>ble particles that fly from those bodies to our <lb xml:id="l323"/><hi rend="smallCaps">olfactory</hi> nerves. How do you prove this, <lb xml:id="l324"/>young Gentleman? says Sir <hi rend="italic">Harry</hi>. Sir, re<lb type="hyphenated" xml:id="l325"/>plied the Philosopher, had you been here ye<lb type="hyphenated" xml:id="l326"/>sterday, you would not have asked this que<lb type="hyphenated" xml:id="l327"/>stion, for, as the wind was North-East, the <lb xml:id="l328"/><hi rend="italic">effluvia</hi> from my Lord's brick-kilns were <lb xml:id="l329"/>ready to suffocate us; but now the wind is <lb xml:id="l330"/>turned to the South-West you observe no <lb xml:id="l331"/>such thing, because those <hi rend="italic">effluvia</hi> are driven <lb xml:id="l332"/>a contrary way.</p>
<p rend="indent5" xml:id="par24">The power which some bodies have of <lb xml:id="l333"/>emitting these <hi rend="italic">effluvia</hi> or steams without be<lb type="hyphenated" xml:id="l334"/>ing visibly diminished, is to me most amaz<lb type="hyphenated" xml:id="l335"/>ing; yet that it is true we know by abundant <lb xml:id="l336"/>experience. A single grain of <hi rend="italic">musk</hi> will scent <lb xml:id="l337"/>a thousand rooms, and send forth these odo<lb type="hyphenated" xml:id="l338"/>riferous particles for a great number of years <lb xml:id="l339"/><fw type="catch" place="bottomRight">without</fw><pb xml:id="p111" n="111"/><fw type="pag" place="topCenter">( 111 )</fw><fw type="sig" place="bottomCenter">L 2</fw>without being spent. Surely these particles <lb xml:id="l340"/>must be extremely small; yet their minute<lb type="hyphenated" xml:id="l341"/>ness is nothing when compared with the par<lb type="hyphenated" xml:id="l342"/>ticles of light, which pervade and find their <lb xml:id="l343"/>way thro' glass, or to the magnetic <hi rend="italic">effluvia</hi> <lb xml:id="l344"/>which pass freely through metallic bodies; <lb xml:id="l345"/>whereas those effluvia that produce the sen<lb type="hyphenated" xml:id="l346"/>sation of smelling, notwithstanding their <lb xml:id="l347"/>wonderful property of scenting all places into <lb xml:id="l348"/>which they are brought, and without any <lb xml:id="l349"/>sensible diminution, are yet too gross to pass <lb xml:id="l350"/>the membranes of a bladder, and many of <lb xml:id="l351"/>them will scarce find their way through <lb xml:id="l352"/>common white paper.</p>
<p rend="indent5" xml:id="par25">There are but few names to express the <lb xml:id="l353"/>infinite number of scents that we meet with. <lb xml:id="l354"/>I know of none but those of <hi rend="italic">sweet, stinking, <lb xml:id="l355"/>rank, musty,</hi> and <hi rend="italic">sour</hi>; for so barren is our <lb xml:id="l356"/>language in this respect, that the rest are <lb xml:id="l357"/>expressed either by degrees of comparison, <lb xml:id="l358"/>or by epithets borrowed from bodies that <lb xml:id="l359"/>produce scent, which must, in many cases, <lb xml:id="l360"/>be very inexpressive; for the smell of a <hi rend="italic">rose</hi>, <lb xml:id="l361"/>of a <hi rend="italic">violet</hi>, and of <hi rend="italic">musk</hi>, though all sweet, are <lb xml:id="l362"/>as distinct as any scents whatever.</p>
<p rend="indent5" xml:id="par26">The next sense under our consideration is <lb xml:id="l363"/><hi rend="smallCaps">Taste</hi>, the organ of which is the <hi rend="smallCaps">tongue</hi> <lb xml:id="l364"/>and the <hi rend="smallCaps">palate</hi>, but principally the tongue. <lb xml:id="l365"/>Ay, and a pretty organ it is, says Lady <hi rend="italic">Ca</hi><lb type="hyphenated" xml:id="l366"/><fw type="catch" place="bottomRight"><hi rend="italic">roline.</hi></fw><pb xml:id="p112" n="112"/><fw type="pag" place="topCenter">( 112 )</fw><hi rend="italic">roline</hi>. When used with your Ladyship's dis<lb type="hyphenated" xml:id="l367"/>cretion, Madam, replied the Philosopher. <lb xml:id="l368"/>But I must observe to your Ladyship, and <lb xml:id="l369"/>the rest of the good company, that though <lb xml:id="l370"/>bodies which emit <hi rend="italic">light, sounds,</hi> and <hi rend="italic">scents</hi>, <lb xml:id="l371"/>are seen, heard, and smelt at a distance; yet <lb xml:id="l372"/>no bodies can produce taste, without being <lb xml:id="l373"/>immediately applied to the organ; for tho' <lb xml:id="l374"/>the meat be placed at your mouth, you know <lb xml:id="l375"/>not what taste it will produce till you have <lb xml:id="l376"/>touched it with your tongue or palate.</p>
<p rend="indent5" xml:id="par27">Though there are an amazing variety of <lb xml:id="l377"/>tastes, yet here, as in scents, we have but a few <lb xml:id="l378"/>general names to express the whole; <hi rend="italic">sweet, <lb xml:id="l379"/>sour, bitter, harsh, smooth,</hi> and <hi rend="italic">rank</hi>, are all <lb xml:id="l380"/>that I can recollect; and our other ideas of <lb xml:id="l381"/>taste are generally conveyed by borrowed <lb xml:id="l382"/>similitudes and expressions as those of <lb xml:id="l383"/><hi rend="italic">scents</hi>. It is surprizing, says the Ambassa<lb type="hyphenated" xml:id="l384"/>dor, that in this age of gluttony, your lan<lb type="hyphenated" xml:id="l385"/>guage should be so barren as not to afford <lb xml:id="l386"/>you words to express those ideas which are <lb xml:id="l387"/>excited by exquisite flavours. Sir, says the <lb xml:id="l388"/>Marquis, this may be easily accounted for. <lb xml:id="l389"/>I must inform your Excellency, that we are <lb xml:id="l390"/>indebted for our most expressive terms to the <lb xml:id="l391"/>Poets, who were never much acquainted <lb xml:id="l392"/>with good eating, and are less so since lite<lb type="hyphenated" xml:id="l393"/>rature has lost its zest. Very true, my Lord, <lb xml:id="l394"/><fw type="catch" place="bottomRight">says</fw><pb xml:id="p113" n="113"/><fw type="pag" place="topCenter">( 113 )</fw><fw type="sig" place="bottomCenter">L 3</fw>says Sir <hi rend="italic">Harry</hi>, their dishes, poor creatures, <lb xml:id="l395"/>have lately been of the mental kind; but <lb xml:id="l396"/>had you a few rich Poets that could afford to <lb xml:id="l397"/>live like people of taste, instead of your sweets <lb xml:id="l398"/>and your sours, and such old fashion terms, <lb xml:id="l399"/>you would have the <hi rend="italic">calapash</hi> and <hi rend="italic">calape</hi> fla<lb type="hyphenated" xml:id="l400"/>vour, the <hi rend="italic">live-lobster</hi> flavour, the <hi rend="italic">whipt-pig</hi> <lb xml:id="l401"/>flavour, and a list of others as long — as <lb xml:id="l402"/>my arm. Fye, Sir <hi rend="italic">Harry</hi>, says the Mar<lb type="hyphenated" xml:id="l403"/>chioness, no more of that, I beg; you know <lb xml:id="l404"/>Lady <hi rend="italic">Caroline</hi> can't bear the name of Barba<lb type="hyphenated" xml:id="l405"/>rity. Nor I neither, says the Ambassador, <lb xml:id="l406"/>but pray what barbarity is there in this, Ma<lb type="hyphenated" xml:id="l407"/>dam? Oh! none at all, replied Sir <hi rend="italic">Harry</hi>, <lb xml:id="l408"/>I only mean to insinuate that some of our <lb xml:id="l409"/>great people are not content with having <lb xml:id="l410"/>food brought from the <hi rend="italic">East</hi> and <hi rend="italic">West Indies</hi>, <lb xml:id="l411"/>and every other part of the world, to gratify <lb xml:id="l412"/>their palates, but they must roast lobsters <lb xml:id="l413"/>alive, and whip young pigs to death to make <lb xml:id="l414"/>them tender. Good God! says the Ambas<lb type="hyphenated" xml:id="l415"/>sador, are there people in <hi rend="italic">England</hi> capable <lb xml:id="l416"/>of such acts of inhumanity? A man that <lb xml:id="l417"/>will do that would murder me, if the law <lb xml:id="l418"/>did not stand between us; and the law is <lb xml:id="l419"/>but a poor screen where humanity is lost and <lb xml:id="l420"/>conscience lulled asleep. I'll apply to the <lb xml:id="l421"/>King my master for my dismission, and no <lb xml:id="l422"/>longer live with a people who have adopted <lb xml:id="l423"/><fw type="catch" place="bottomRight">such</fw><pb xml:id="p114" n="114"/><fw type="pag" place="topCenter">[ 114 ]</fw>such diabolical customs. The Ambassador <lb xml:id="l424"/>was so much in a passion, that it was with difficulty <lb xml:id="l425"/>my Lord Marquis pacified him; <lb xml:id="l426"/>and poor Lady <hi rend="italic">Caroline</hi>, whose kind soul <lb xml:id="l427"/>sympathizes with every creature in distress, <lb xml:id="l428"/>was in tears at the bare rehearsal of those acts <lb xml:id="l429"/>of cruelty. Upon which the Baronet was <lb xml:id="l430"/>blamed by all the company, except myself, <lb xml:id="l431"/>and, I think, he never shewed so much <lb xml:id="l432"/>good sense in his life; for there was one in <lb xml:id="l433"/>the room who deserved the reproof.</p>
<p rend="indent5" xml:id="par28">When the Ambassador had sat down with <lb xml:id="l434"/>a sigh, and Lady <hi rend="italic">Caroline</hi> had wiped the <lb xml:id="l435"/>precious pearly drops from her cheeks, our <lb xml:id="l436"/>Philosopher arose and thus pursued his Lec<lb type="hyphenated" xml:id="l437"/>ture.</p>
<p rend="indent5" xml:id="par29">I have already taken notice of four of our <lb xml:id="l438"/>senses, and am now come to the fifth and <lb xml:id="l439"/>last, I mean that of the <hi rend="smallCaps">Touch</hi>, which is <lb xml:id="l440"/>a sense spread over the whole body, tho' it <lb xml:id="l441"/>is more particularly the business of the hands <lb xml:id="l442"/>and fingers; for by them the tangible quali<lb type="hyphenated" xml:id="l443"/>ties of bodies are known, since we discover <lb xml:id="l444"/>by the <hi rend="italic">touch</hi> of the fingers, and sometimes, <lb xml:id="l445"/>indeed, by the <hi rend="italic">touch</hi> of other parts of the <lb xml:id="l446"/>body, whether things are <hi rend="italic">hard, soft, rough, <lb xml:id="l447"/>smooth, wet, dry, &amp;c</hi>. But the qualities which <lb xml:id="l448"/>most affect this sense are <hi rend="italic">heat</hi> and <hi rend="italic">cold</hi>, and <lb xml:id="l449"/>which, indeed, are the great engines of Na<lb type="hyphenated" xml:id="l450"/><fw type="catch" place="bottomRight">ture;</fw><pb xml:id="p115" n="115"/><fw type="pag" place="topCenter">[ 115 ]</fw>ture; for by a due temperament of those <lb xml:id="l451"/>two opposite qualities most of her produc<lb type="hyphenated" xml:id="l452"/>tions are formed.</p>
<p rend="indent5" xml:id="par30">What we call <hi rend="italic">heat</hi> is occasioned by the <lb xml:id="l453"/>agitation of the insensible parts of the body <lb xml:id="l454"/>that produces in us that sensation; and when <lb xml:id="l455"/>the parts of a body are violently agitated, <lb xml:id="l456"/>we say, and indeed we feel, that body is <lb xml:id="l457"/><hi rend="italic">hot</hi>, so that that which to our sensation is <lb xml:id="l458"/><hi rend="italic">heat</hi>, in the object is nothing but <hi rend="italic">motion</hi>. <lb xml:id="l459"/>Hey-day, says Lady <hi rend="italic">Caroline</hi>, what sort of <lb xml:id="l460"/>Philosophy is this? Why, Madam, says Sir <lb xml:id="l461"/><hi rend="italic">Harry</hi>, this is a position which has been laid <lb xml:id="l462"/>down by these airy Gentlemen for a long <lb xml:id="l463"/>time, but which never has been proved by <lb xml:id="l464"/>experiment. Take care, Baronet, says the <lb xml:id="l465"/>Marquis, or you'll forfeit all pretensions to <lb xml:id="l466"/>Philosophy. The forfeiture, my Lord, is <lb xml:id="l467"/>made already, says the Philosopher; Sir <lb xml:id="l468"/><hi rend="italic">Harry</hi> has been bold enough to deny that <lb xml:id="l469"/>which experience every day confirms for <lb xml:id="l470"/>truth. If what we call Heat is not motion, <lb xml:id="l471"/>or occasioned by the motion of bodies, how <lb xml:id="l472"/>came my Lord's mill to take fire the other <lb xml:id="l473"/>day, when it was running round without a <lb xml:id="l474"/>proper supply of corn? And how came your <lb xml:id="l475"/>post-chariot to fire while running down <lb xml:id="l476"/><hi rend="italic">Breakneck hill</hi>, Sir <hi rend="italic">Harry?</hi> Consider, there <lb xml:id="l477"/>was nobody with a torch under the axle- <lb xml:id="l478"/><fw type="catch" place="bottomRight">tree;</fw><pb xml:id="p116" n="116"/><fw type="pag" place="topCenter">( 116 )</fw>tree; but this is a part of Philosophy known <lb xml:id="l479"/>even to the poor ignorant <hi rend="italic">Indians</hi>, who, <lb xml:id="l480"/>when hunting at a great distance from home, <lb xml:id="l481"/>and wanting fire to dress their meat, take <lb xml:id="l482"/>a bow and a string and rub two pieces of <lb xml:id="l483"/>wood together till they produce flame. But <lb xml:id="l484"/>you may see, Sir <hi rend="italic">Harry</hi>, that heat is occa<lb type="hyphenated" xml:id="l485"/>sioned by the motion of bodies, by only rub<lb type="hyphenated" xml:id="l486"/>bing this piece of smooth <hi rend="italic">brass</hi> on the table <lb xml:id="l487"/>--stay, I'll rub it. — It must be done briskly. <lb xml:id="l488"/>There, now you'll feel it hot; but cease <lb xml:id="l489"/>this motion for a time, and the brass will <lb xml:id="l490"/>become cold again; whence we may infer, <lb xml:id="l491"/>that as heat is nothing but the insensible parti<lb type="hyphenated" xml:id="l492"/>cles of bodies put into motion, so cold, <lb xml:id="l493"/>on the contrary, is occasioned by the cessa<lb type="hyphenated" xml:id="l494"/>tion of the motion of those particles, or their <lb xml:id="l495"/>being placed in a state of rest.</p>
<p rend="indent5" xml:id="par31">But bodies appear <hi rend="italic">hot</hi> or <hi rend="italic">cold</hi> in proportion <lb xml:id="l496"/>to the temperament of that part of the hu<lb type="hyphenated" xml:id="l497"/>man body to which they are applied; so <lb xml:id="l498"/>that what seems hot to one, may not seem so <lb xml:id="l499"/>to another: This is so true, that the same <lb xml:id="l500"/>body felt by the two hands of the same man, <lb xml:id="l501"/>may at the same instant of time appear warm <lb xml:id="l502"/>to the one hand, and cold to the other, if <lb xml:id="l503"/>with the one hand he has been rubbing any <lb xml:id="l504"/>thing, while the other was kept in a state of <lb xml:id="l505"/>rest; and for no other reason but because <pb xml:id="p117" n="117"/><fw type="pag" place="topCenter">[ 117 ]</fw>the motion of the insensible particles of that <lb xml:id="l506"/>hand with which he has been rubbing, will <lb xml:id="l507"/>be more brisk than the particles of the other <lb xml:id="l508"/>which was at rest.</p>
<p rend="indent5" xml:id="par32">I have mentioned those objects which are <lb xml:id="l509"/>peculiar to each of our senses, as <hi rend="italic">light</hi> and <lb xml:id="l510"/><hi rend="italic">colour</hi> to the <hi rend="italic">sight</hi>; <hi rend="italic">sound</hi> to the <hi rend="italic">hearing</hi>; <lb xml:id="l511"/><hi rend="italic">odors</hi> to the <hi rend="italic">smell</hi>, &amp;c. but there are two <lb xml:id="l512"/>others common to all the senses, which de<lb type="hyphenated" xml:id="l513"/>serve our notice, and these are <hi rend="italic">pleasure</hi> and <lb xml:id="l514"/><hi rend="italic">pain</hi>, which the senses may receive by their <lb xml:id="l515"/>own peculiar objects; for we know that a <lb xml:id="l516"/>proper portion of light is pleasing, but that <lb xml:id="l517"/>too much offends the eye; some sounds de<lb type="hyphenated" xml:id="l518"/>light, while others are disagreeable, and <lb xml:id="l519"/>grate the ear; so heat, in a moderate de<lb type="hyphenated" xml:id="l520"/>gree, is very pleasant; yet that heat may be <lb xml:id="l521"/>so increased as to give the most intolerable <lb xml:id="l522"/>pain. But these things are too well known <lb xml:id="l523"/>to be longer insisted on.</p>
<p rend="indent5" xml:id="par33">Now from the <hi rend="italic">ideas</hi> or <hi rend="italic">conceptions</hi> formed <lb xml:id="l524"/>in the mind, by means of our senses, and the <lb xml:id="l525"/>operations of the mind itself, are laid the <lb xml:id="l526"/>foundation of the human understanding, the <lb xml:id="l527"/>lowest degree of which is <hi rend="italic">perception</hi>; and to <lb xml:id="l528"/>conceive a right notion of this, we must dis<lb type="hyphenated" xml:id="l529"/>tinguish the first objects of it, which are <lb xml:id="l530"/><hi rend="italic">simple ideas</hi>, such as are represented by the <lb xml:id="l531"/>words, <hi rend="italic">red, blue, bitter, sweet,</hi> &amp;c. from the <lb xml:id="l532"/><fw type="catch" place="bottomRight">other</fw><pb xml:id="p118" n="118"/><fw type="pag" place="topCenter">[ 118 ]</fw>other objects of our senses; to which we <lb xml:id="l533"/>may add the internal operations of our own <lb xml:id="l534"/>minds, or the objects of reflection, such as <lb xml:id="l535"/>are <hi rend="italic">thinking, willing,</hi> &amp;c. for all our ideas <lb xml:id="l536"/>are first obtained by <hi rend="italic">sensation</hi> and <hi rend="italic">refle<unclear reason="copy" cert="medium">ct</unclear>ion</hi>. <lb xml:id="l537"/>The mind having gained variety of <hi rend="italic">simple <lb xml:id="l538"/>ideas</hi>, by putting them together, forms what <lb xml:id="l539"/>are called <hi rend="italic">compounded</hi> or <hi rend="italic">complex ideas</hi>, as <lb xml:id="l540"/>those signified by the words, <hi rend="italic">man, horse, <lb xml:id="l541"/>marygold, windmill</hi>, &amp;c.</p>
<p rend="indent5" xml:id="par34">The next operation of the mind (or of the <lb xml:id="l542"/>understanding) in its progress to knowledge, is <lb xml:id="l543"/>that of abstracting its ideas; for by abstraction <lb xml:id="l544"/>they are made general; and a <hi rend="italic">general idea</hi> <lb xml:id="l545"/>is to be considered as separated from time and <lb xml:id="l546"/>place, and lodged in the mind to represent <lb xml:id="l547"/>any particular thing that is conformable to it.</p>
<p rend="indent5" xml:id="par35"><hi rend="italic">Knowledge</hi>, which is the highest degree <lb xml:id="l548"/>of the speculative faculties, consists in the <lb xml:id="l549"/>perception of the truth of affirmative or ne<lb type="hyphenated" xml:id="l550"/>gative propositions; and this perception is <lb xml:id="l551"/>either immediate or mediate. When, by <lb xml:id="l552"/>comparing two ideas together in the mind, <lb xml:id="l553"/>we perceive their agreement or disagreement, <lb xml:id="l554"/>as that black is not white; that the whole is <lb xml:id="l555"/>bigger than a part; that two and two are <lb xml:id="l556"/>equal to four, &amp;c. it is called immediate per<lb type="hyphenated" xml:id="l557"/>ception, or <hi rend="italic">intuitive</hi> knowledge; and as the <lb xml:id="l558"/>truth of these and the like propositions is <lb xml:id="l559"/><fw type="catch" place="bottomRight">so</fw><pb xml:id="p119" n="119"/><fw type="pag" place="topCenter">[ 119 ]</fw>so evident as to be known by a simple intui<lb type="hyphenated" xml:id="l560"/>tion of the ideas themselves, they are also <lb xml:id="l561"/>called <hi rend="italic">self-evident propositions</hi>.</p>
<p rend="indent5" xml:id="par36">Mediate perception, is when the agreement <lb xml:id="l562"/>or disagreement of two ideas is made known <lb xml:id="l563"/>by the intervention of some other ideas: <lb xml:id="l564"/>Thus if it be affirmed that my Lord's bay <lb xml:id="l565"/>horse is as high as my father's, the agree<lb type="hyphenated" xml:id="l566"/>ment or disagreement may be seen by apply<lb type="hyphenated" xml:id="l567"/>ing the measure to both; and this is <lb xml:id="l568"/>called <hi rend="italic">demonstration</hi>, or <hi rend="italic">rational knowledge</hi>. <lb xml:id="l569"/>The dimensions of any two bodies which <lb xml:id="l570"/>cannot be brought together, may be thus <lb xml:id="l571"/>known, by the same measure being applied <lb xml:id="l572"/>to them both.</p>
<p rend="indent5" xml:id="par37">But the understanding is not confined to <lb xml:id="l573"/>certain truth; it also judges of <hi rend="italic">probability</hi>, <lb xml:id="l574"/>which consists in the <hi rend="italic">likely</hi> agreement or dis<lb type="hyphenated" xml:id="l575"/>agreement of ideas; and the assenting to any <lb xml:id="l576"/>proposition as probable, is called <hi rend="italic">opinion</hi>, or <lb xml:id="l577"/><hi rend="italic">belief</hi>. — We have now finished this Course of <lb xml:id="l578"/>Lectures. I hope not, says Lady <hi rend="italic">Caroline</hi>, <lb xml:id="l579"/>with some emotion! — Why, Madam, return<lb type="hyphenated" xml:id="l580"/>ed the Philosopher, we have taken a cursory <lb xml:id="l581"/>view of natural bodies, and their causes and <lb xml:id="l582"/>effects; which I have endeavoured to explain <lb xml:id="l583"/>in such a manner as to be intelligible, at <lb xml:id="l584"/>least, if not entertaining; and pray what <lb xml:id="l585"/>more did your Ladyship expect? Sir, replied <lb xml:id="l586"/><fw type="catch" place="bottomRight">the</fw><pb xml:id="p120" n="120"/><fw type="pag" place="topCenter">[ 120 ]</fw>the Lady, I am greatly pleased with the ac<lb type="hyphenated" xml:id="l587"/>count you have given us, and I thank you, <lb xml:id="l588"/>Sir, for the pains you have taken to answer <lb xml:id="l589"/>the many questions I have troubled you <lb xml:id="l590"/>with. What I had farther to hope, was, <lb xml:id="l591"/>that you would have given us, when you <lb xml:id="l592"/>was on the subject of Animals, some <lb xml:id="l593"/>strictures on the cruelty with which they <lb xml:id="l594"/>are too often treated; and have thrown in <lb xml:id="l595"/>reflections and observations tending to in<lb type="hyphenated" xml:id="l596"/>force in mankind a different conduct. <lb xml:id="l597"/>This I wished for, and should have been <lb xml:id="l598"/>glad to have had Sir <hi rend="italic">Thomas</hi> and his Lady <lb xml:id="l599"/>here at the same time; who are both ex<lb type="hyphenated" xml:id="l600"/>tremely fond of their little domestic crea<lb type="hyphenated" xml:id="l601"/>tures, and I admire them for their tender<lb type="hyphenated" xml:id="l602"/>ness and compassion. These feelings and <lb xml:id="l603"/>sentiments of the human heart, Madam, says <lb xml:id="l604"/>the Philosopher, add much to the dignity of <lb xml:id="l605"/>our nature, and I am greatly delighted with <lb xml:id="l606"/>such behaviour; but I am afraid, Lady <hi rend="italic">Ca<lb type="hyphenated" xml:id="l607"/>roline</hi>, that we often mistake characters of <lb xml:id="l608"/>this kind, and take that for humanity and <lb xml:id="l609"/>tenderness, which is only the effect of fancy <lb xml:id="l610"/>or self love. That Sir <hi rend="italic">Thomas</hi> has compas<lb type="hyphenated" xml:id="l611"/>sion, I grant you; but I am afraid it is <lb xml:id="l612"/>only for himself. He loves his dogs and <lb xml:id="l613"/>horses, because his dogs and horses give him <lb xml:id="l614"/>pleasure, but to other creatures that afford <lb xml:id="l615"/><fw type="catch" place="bottomRight">him</fw><pb xml:id="p121" n="121"/><fw type="pag" place="topCenter">[ 121 ]</fw><fw type="sig" place="bottomCenter">M</fw>him none, he is absolutely insensible. I <lb xml:id="l616"/>have seen him, even at <hi rend="italic">Christmas</hi>, feed his <lb xml:id="l617"/>pretty pupps, as he calls them, with delica<lb type="hyphenated" xml:id="l618"/>cies; but rave, at the same time, in a mer<lb type="hyphenated" xml:id="l619"/>ciless manner, at poor children who were <lb xml:id="l620"/>shivering at his gate, and send them away <lb xml:id="l621"/>empty handed. Our neighbour Sir <hi rend="italic">William</hi> <lb xml:id="l622"/>is also of the same disposition; he will not <lb xml:id="l623"/>sell a horse, that is declining, for fear he <lb xml:id="l624"/>should fall into the hands of a master who <lb xml:id="l625"/>might treat him with cruelty; but he is <lb xml:id="l626"/>largely concerned in the slave trade (which, <lb xml:id="l627"/>I think, is carried on by none but <hi rend="italic">we good <lb xml:id="l628"/>Christians</hi>, to the dishonour of our <hi rend="italic">celestial <lb xml:id="l629"/>Master)</hi> and makes no difficulty of separat<lb xml:id="l630"/>ing the husband from the wife, the parents <lb xml:id="l631"/>from the children, and all of them (as well <lb xml:id="l632"/>as our own people, who are procured by his <lb xml:id="l633"/><hi rend="italic"><unclear reason="copy" cert="low">crimps</unclear>,)</hi> from their native country, to be <lb xml:id="l634"/>sold in a foreign market, like so many horses, <lb xml:id="l635"/>and often to the most merciless of the human <lb xml:id="l636"/>race. I remember him in great distress for <lb xml:id="l637"/>his pointer <hi rend="italic">Phillis</hi>, who had lost her <hi rend="italic">puppies</hi>; <lb xml:id="l638"/>but the same afternoon I saw him, without <lb xml:id="l639"/>the least compunction of mind, press a poor <lb xml:id="l640"/>man into the sea service, and tear him from <lb xml:id="l641"/>his wife and children; for no other <hi rend="italic">crime</hi>, <lb xml:id="l642"/>but because he had fought bravely for his <lb xml:id="l643"/>King and country in the last war, and be<lb type="hyphenated" xml:id="l644"/><fw type="catch" place="bottomRight">ing</fw><pb xml:id="p122" n="122"/><fw type="pag" place="topCenter">[ 122 ]</fw>ing now settled in business, and having a fa<lb type="hyphenated" xml:id="l645"/>mily, did not chuse to enter the service a<lb type="hyphenated" xml:id="l646"/>gain. Is this humanity, Madam? Is this <lb xml:id="l647"/>morality? But above all, is this Christiani<lb type="hyphenated" xml:id="l648"/>ty? And are these the blessed effects of the <lb xml:id="l649"/>liberty we boast of? — I don't expect a reply, <lb xml:id="l650"/>Lady <hi rend="italic">Caroline</hi>, for I shall have occasion to <lb xml:id="l651"/>say much more on these subjects in my next <lb xml:id="l652"/>course of Lectures, and then, perhaps, you <lb xml:id="l653"/>will honour me with your observations. But <lb xml:id="l654"/>in the meantime don't let us be misled by <lb xml:id="l655"/>specious pretences. We cannot judge of any <lb xml:id="l656"/>man, Madam, by one single action, but by <lb xml:id="l657"/>the tenour and result of all his actions, and <lb xml:id="l658"/>this requires deep penetration and an inti<lb type="hyphenated" xml:id="l659"/>mate knowledge of human life.</p>
<p rend="indent5" xml:id="par38">Benevolence, Lady Caroline, should be <lb xml:id="l660"/>universal, for it is an emanation of the Su<lb type="hyphenated" xml:id="l661"/>preme Being, whose mercy and goodness are <lb xml:id="l662"/>extended to all his creatures; as ours also <lb xml:id="l663"/>should be, for they are fellow tenants with us <lb xml:id="l664"/>of the globe we inhabit.</p>
<p rend="indent5" xml:id="par39">I have often thought, Madam, that most <lb xml:id="l665"/>of the mischiefs which embarrass society, and <lb xml:id="l666"/>render one man contemptible to another, <lb xml:id="l667"/>are owing to inordinate <hi rend="italic">ambition</hi> or extreme <lb xml:id="l668"/>love of <hi rend="italic">power</hi>, and of <hi rend="italic">wealth</hi>, the means <lb xml:id="l669"/>by which it is procured; for all the gold a <lb xml:id="l670"/>man possesses beyond that portion which is <lb xml:id="l671"/><fw type="catch" place="bottomRight">requisite</fw><pb xml:id="p123" n="123"/><fw type="pag" place="topCenter">[ 123 ]</fw><fw type="sig" place="bottomCenter">M 2</fw>requisite for himself and family, only serves <lb xml:id="l672"/>to inflame his ambition; as all the wine we <lb xml:id="l673"/>drink more than is necessary to recruit the <lb xml:id="l674"/>drooping spirits, answers no other purpose <lb xml:id="l675"/>but to intoxicate the mind.</p>
<p rend="indent5" xml:id="par40">I have seen a book, Lady <hi rend="italic">Caroline</hi>, in <lb xml:id="l676"/>my Pappa's library, which gives some ac<lb type="hyphenated" xml:id="l677"/>count of one <hi rend="italic">Lycurgus</hi>, an old <hi rend="italic">Grecian</hi> Law<lb type="hyphenated" xml:id="l678"/>giver, with whose character you ought to be <lb xml:id="l679"/>acquainted. — This man, Madam, was of <lb xml:id="l680"/>opinion, that religion, virtue, and good <lb xml:id="l681"/>manners, were the only natural cements and <lb xml:id="l682"/>preservatives of liberty, peace, and friendship; <lb xml:id="l683"/>which he found had been destroyed and ex<lb type="hyphenated" xml:id="l684"/>tirpated by means of wealth and self-interest; <lb xml:id="l685"/>he therefore prohibited the use of gold and <lb xml:id="l686"/>silver, and all kinds of luxury in the state, <lb xml:id="l687"/>and established such a plan for the education <lb xml:id="l688"/>of youth of every denomination, as was most <lb xml:id="l689"/>likely to confirm and habituate them in the <lb xml:id="l690"/>practice of religion and virtue, and secure to <lb xml:id="l691"/>the <hi rend="italic">Spartans</hi> and their posterity the blessings <lb xml:id="l692"/>of liberty and peace.</p>
<p rend="indent5" xml:id="par41">The event proved that his institutions <lb xml:id="l693"/>were founded on sound policy, and a perfect <lb xml:id="l694"/>knowledge of human nature; for in the <lb xml:id="l695"/>space of five hundred years, that is to say, <lb xml:id="l696"/>from the time of <hi rend="italic">Lycurgus</hi> to the introduction <lb xml:id="l697"/>of wealth into the state by <hi rend="italic">Lysander</hi>, in the reign <lb xml:id="l698"/><fw type="catch" place="bottomRight">of</fw><pb xml:id="p124" n="124"/><fw type="pag" place="topCenter">[ 124 ]</fw>of the first <hi rend="italic">Agis</hi>, there was no mutiny among <lb xml:id="l699"/>the people; every man submitted chear<lb type="hyphenated" xml:id="l700"/>fully to the laws of <hi rend="italic">Lycurgus</hi>, and all were so <lb xml:id="l701"/>united and powerful in consequence of their <lb xml:id="l702"/>virtue, sobriety, and the martial discipline he <lb xml:id="l703"/>had established (which was that of a national <lb xml:id="l704"/>militia) that <hi rend="italic">Sparta</hi>, a very small and inconsidera<lb type="hyphenated" xml:id="l705"/>ble State, not only gave laws to the rest of <lb xml:id="l706"/><hi rend="italic">Greece</hi>, but made even the <hi rend="italic">Persian</hi> Monarchs <lb xml:id="l707"/>tremble, though masters of the richest and <lb xml:id="l708"/>most extensive empire in the world. But <lb xml:id="l709"/>when these great and virtuous people of <lb xml:id="l710"/><hi rend="italic">Sparta</hi> had conquered <hi rend="italic">Athens</hi>, and from <lb xml:id="l711"/>thence introduced wealth and luxury into <lb xml:id="l712"/>their own country, they lost their virtue, <lb xml:id="l713"/>dwindled to nothing, and were themselves <lb xml:id="l714"/>enslaved. Nor is this a matter of wonder; <lb xml:id="l715"/>for where Religion and Virtue are set at a <lb xml:id="l716"/>distance, and Wealth leads the way to posts <lb xml:id="l717"/>of honour and trust, some people will stick <lb xml:id="l718"/>at nothing to obtain gold; but were dignities <lb xml:id="l719"/>of this kind conferred on the most deserving, <lb xml:id="l720"/>and none but men of virtue and superior abi<lb type="hyphenated" xml:id="l721"/>lities promoted to places of trust and power, <lb xml:id="l722"/>there would be no frauds in the State, or vi<lb type="hyphenated" xml:id="l723"/>olence among the People, and we might <lb xml:id="l724"/>then hope to enjoy the felicities of the <hi rend="italic">Gol<lb type="hyphenated" xml:id="l725"/>den Age</hi>.</p>
