liturtiryA gives rise to challenging questions which are not altogetherersy to answer. Is it a relation? A relation betweetr objects, or betweeirr rDes or signs of objects? ln my Begrifrsschdltl assumed the latter.2 The

'rrsons which seem to favour this are the following: a = a ar,d a = b

i.c obviously statements of difiering cognitive value lErkenntnisuenl;,r d holds d pnbn and, according to Kant, is to be labelled anabtic,$hilc statements of the folm a = , often contain very valuable exten-lxDs of our knowledge and cannot always be established d rn;r,- The,liscovery thar the rising sun is not new every moming, but always therrmc, was one of the most fertile asbonomical discoveries.

relarion would hold between the names or signs only in so far as dleynamed or designated something. It would be mediated by $e connec-tion of each of rle two signs with $e same designared thing. But thisis arbitrary. Nobody can be forbidd€n ro use any arbitradly producibleevent or object as a sign for something. In that case tle sentence d =,would no longer be concerned wifi the subiect matter, bur only withits mode of designation; we would exprcss no proper howledge by irgmeans. But in many cases this is jusr what we want to do. If rhe sign'd' is distinguished ftom fie sign 'r' only as an object (here, by meangofits shape), not as a sign (i.e. not by the manner in which ir designat€ssomething)j the cognitive value of d = d becomes essenrially equal rothat of d = ,, provided a = , is true. A difference can arise only if rhcdifference between the signs corresponds ro a difference in the mode ofpresentation [Art dcs Gegebenseins] of the rhing designated. I-et d, ,, .be the lines €onnectins the vertices of a triangle wid de midpoinrs ofthe opposite sides. The point ofintersecrion of d and, is then the samcas the point ofintersection of, and c. So we have different designationsfor the same point, and ihes€ names ('poinr of intersection ofd and,','point of int€rsecrion of , and c') likewise indicate the mode of pres-ertationj and hence the starem€nr conrains actual knowledge.r

h is natural, now, to think of dere being connected wirh a sign (name,combination ofwords, written mark), besid€s thar which rhe sign desig-nates, which may be called thc Bdde&r,/rA of the sign, also what I shouldlike to call rhe rerse of lhe sign, wherein the mode of prcsentarion iscontained. ln our elample, accodingly, the Brde rfi?g ofde expres-sions'th€ point ofinlersection of d and ,'and'the point ofintersectionof , and .' would be the same, but nor rheir sense. The Bedeurrns oi'Evening Star'would be the sam€ as r-har of 'Moming Srar', but not thc

In order to speak of the sense of an expression I' one may siuse the pb.rase '$e sense of the expression '7"'. In indirect speechtalks about the senseJ e.g.r of anothe! pefson's remarks. It is quite clcfiat irr this way of speaking q,ords do not have rheir customarybut designare [rede,ref] what is usually rheir sense. In order to havc Isholt expression, we will say: in indlecr speech, words are used td,reci! ot have $ei i direct Bedcutung. We distinguish accordingly thacusromary fto'Jn t\e indiect Bedeutung of

from its ,r/rrrr sense. The rlrd]-le.r Bedeutung of a word is accordinglyits customary sense. Such exceptions must always be bome in mind ltthe mode of connection between sign, sense and Bedeutung in patli.\tlttcases is to be correctly undersrood.

29 Tl\e Bedeutung and sense of a sign are to be distinguished ftom rhtassociated idea [VorstuAuis].7f the Bedzutu s of a sien is an objc.tperceivable by r}le senses, my idea of it is an intemal image, arisinffrom memories of sense impressions which I have had and acts, bothintemal and €xtemal, which I have perform€d.c Such an idea is ofrcnimbued with feeling the clarity of its separate parrs varies and oscll.lates. The same sense is not always connected, even in the same mnnlwith the same idea. The idea is subiective: one man's idea is nor thttof another. There result, as a matter of course, a variety of differenc€ain the ideas associated with the same sense. A painter, a horsemanland a zoologist will probably connect diff€rent ideas wirl dre namt'Bucephalus'. This constitutes an essential distindion between rhe id6tand the sigl's sense, which may be fie common property of manypeople, and so is not a pan or a mode of the individual mind. For onacan hardly deny that mankind has a common storc of rhoughts whichis transmifted ftom one generation ro another.D

In the light of this, one need have no scruples in speaking simplyoft e sense, whereas in the case ofan idea one must, srricdy speakinS,add whom it belongs to and at what time. It might pefiaps be said: iuutas one man connecrs this idea, and another that idea, with the sama

\v,'rd, so also one man can associate rhis sense and another that sense.

I lll r rher€ still rcmains a difference in the mode of connection. They are

r|r pf€vented from graspi[g the same sense; but th€y cannot have thetnc idea. Si dlto idcn laciunt, non est idem.lf r\xo persons picture the

{IDc thing, each srill has his own idea. It is indeed sometimes possibler,, cstablish diferences in the ideas, or even in the seNarionsj ofd fer-{rr nenj bur an exact comparison is not possible, because we cannot|,.'vr bo$ ideas rogether in the same consciousness.

II]e Bedeutuns of ^

proper name is &e object itself which we desig-

'rrc by using it; the idea which we have in that case is wholly subject-rvri in between lies the sense, which is indeed no longer subiective lilerllr idea, but is yet not the object itself. Th€ following analogy willt(rhrps clariiy these rclationships. Somebody observes rhe Moon t][ough

'r r.lcscope. I compare the Moon itself to the Brdedrrg; it is the obiect

,'l rhc obseflarion, mediated by the ftal image proiected by the objectultr\s in fie inredor of the telescope, and by the r€tinal image of the,,lrcrver. The formff I compare to the sense, the latt€r is like the idea

"t rttninon lAnscha ung). The optical image in the telescope is indeed

'tr(, sided and dependent upon the standpoint of observation; but it isirrll otrjective, inasmuch as it can be used by several obsewers. At anyr rc it could be arranged for seveml to use it simultaneously. But each

'ir would have his oirn retinal image. On account of the diverse shapes,,1 rl)r observers' eyes, even a geometrical congruence could hardly be

, lricvcd, and an actual coincidence would be out of th€ question. Thisrrlogy might b€ developed still further, by assuming A's retinal image

llrfilc visible to B; or A might also see his oivn rerinal image in a minor.lr rhis way we miSht pefiaps show how an idea can irself be taken as

.' object, but as such is not for the obserlr'er what it directly is for the

Itr'n,n having the idea. But to pursue this would take us too far afield.wc can now recognize three levels of differ€nce betwe€n words, ex-

I'rr\sions, or whole sentences. The drfferenc€ may concem at most ther,l' rs, or the sense but not the Bedzutung, or, fn lly, t17e Bedeuturlg

^s(' ll. with respecr to I the first level, it is to be noted that, on account,'l rl,( uncenain connection of ideas with words' a diference may holdl,'r ('rc personr which anoder does not find. The drfference betweeni r.x'rslation and fte odginal text should propetly not overstep the lir:stl, \ .1. fo the possible diferences here belong also the colouring and shad-I rrl lvhich poetic eloquenc€ seel.s to give to the sense.

'|,rlurg are not objective, and must be evoked by each hearer or readerr, ( ( ding to the hints of the poet or the speaker. Without some afrnityr, l,uDran ideas an would cenainly be impossible; but it can never be, \,( rly determin€d how far the intentions of rhe poet are realized.

aroused in th€ hearer by a woid shall not be contused with its sense orits BedzutunE.

To make shon and exact expressions possible, let the following phraseo-logy be established:

A proper nme (word, si8n, combinaiion of signs, expression) er?Erres irssense, stak^ lor lbedeubrl ot daisaax' [bezenhnetl i$ B..|eatu,s. By enptoy-ing a siSn we er?ress its sense and designate its Bede!l!,r'.

Idealists or sceprics will perhaps long since have objected: 'You tallswithout further ado, of the Moon as an obiectj but ho\rr do you knowthat the name "the Moon" has any Bedeutuns? How do you know thatanlthing wharsoev has a Bedeunng?' I reply that when we say 'rheMoon', we do not inend to speak of our idea of rhe Moon, nor arewe saiisfied with the sense alone, but we presuppose

^ BedN tung. To

assume that in the sentenc€ 'The Moon is small$ than the Eanh' theidea of r}le Moon is in question, would be flarly ro misundersrand thesense. If this is what the speak€r wanted, he would use the phrase 'myidea of the Moon'. Now we can of course be mistaken in the pr€supposi-tion, and such mistakes have indeed occuned. But &e question whetherthe presupposition is pefiaps always mistaken need I not be answer€dhere; in order to iusrify speaktng of the Bedeuung of a sign, it is enough,at firsr, to point our our inteniion in speaking or thinking. (We must rhenadd rhe rcservarion: provided such

^ Bedeutuns exists.)

So far we have considered the sense and Bedcutung only of suchexpressions, words, or signs as we have called proper names. W€ nowinquire conceming the sense

^nd Be.leutu s oI an entire assedoric sen-

tence. Such a sentence contains a thought.r Is .his thoughr, now, to beregarded as its sense or its Beder&nA? Let us assume for the rime beingthat the sentence has a Bedeutung.lf we no' replace one word of rhesentence by another haviaq the same Bedeutung, but a differem sensejthis can have no effect upo'r the Bed.urung of the s€mence. Yet we cansee that in such a case th€ thought changes; since, e.g., the thought inthe sentence 'The Moming Srar is a body illuminated by the Sun'differs ftom that in the sentence 'The Evening Star is a body ilumin-ated by the Sun'. Anybody who did not know that rhe Evening Star isthe Moming Star mighr hold rhe one thought to be true, the other false.The thought, accordingly, cannot be the Brdrxt"ug of the sentence, butmust rather be considered as its sense. \I.rhat is the position Dow withrcgard to the Bedeatung? Have we a right even to inquire about it? Isit possible rhat a sentence .s a whole has or y a s ense, b$ no Bedeutungl

At any rate, one might expect thar such sentences occurJ just as thereare pans of sentences having sense bt no Bedeutung. And senrenceswhich contain proper names wirhout Bed?rrMs wilt be of *lis kind. Thesentence 'Odysseus was set ashore at fthaca while sound asleep' obvi_ously has a sense. Bur since ir is doubtful whether rhe name ,Odysseus,,

occurring therein, has a Be.Jelrrr,& ir is also doubrful wherher rhe wholesentence does. Yer it is certainr neverrhelessJ rhar anyone who seriousivrook rhe senlence ro be (rue or faLe woutd ascribe ro rhe name .Odvseuq.J Brd"rrrrA. nor merelv a

that the predicate is affimed or denied. ',t0hoevcr does not admit r}l€name has a Bedeutung can neither apply nor wirbhold the predicare. Butin that case it would be superfluous to advance to tIrc Bedeutune ol r\enamej one could be sarisqed wirl rhe sense, if one wanted ro go noturther than the rhought. If it were a question only of the sense of thesentence, rhe thoughrr it would be needless to bolher wirtr rhe Bede,orl,gof a pan of the senrence; only the sense, not r}l e Bedeutung, of it:le pattis relevanr ro th€ sense of the whole senrence. The thought remains thesrme wherhe! 'Odysseus' has a Bed€|rlza or not. The facr rhat we con_cem ourselves ar all abo the Bed.uane of a pan of the sertence indic_xtcs that we generally recogniz€ and expecr a B€drlrrlr!, for the senrencertself. The thoughr los€s value for us as soon as we rccognize that theBcde t"ry of one of its parts is missing. W€ are th€refore jus.ified in notbcing satisfied with the sense of a sentence, and in inquiring also as toits Bdderrrlrg. But now why do we wanr every proper name to have noronly a sense, but also a Bederrrrg? lghy is the thought not enough fortrs? Because, and to rhe extenr tharr we are concemed with irs truth_value. This is not always the case.In hearing an epic poem, for instance..rpr trom rhe cuphony ot rhe lansuage $e are inreresled only in Lhescnse of rhe sentences and the images and feelings thereby arc,rsed. Thequestion of rruth would cause us to abandon aesrhetic delighr for anrLlitude of scientific investigarion.

uuth-values. For brevity I call the one the True, th€ other rhe False.Every assenoric sentence concerned with the B?derrrrA of its words istherefore to be regarded as a proper name, and its Bedeutune, 1f ir hasone, is either the True or the False. These two objects are recognized,if only implicitly, by everybody who judges somethirg to be tme - andso even by a sceptic. The designation of the rurh-values as obtects mayappear to be an arbitmry fancy or perhaps a mere play upon words, ftomwhich no profound consequences could be drawn. W}tat I am calling anobject can be more exacdy discussed only in cormection with conceptand relation. I will resefte dis for anoth€r article.5 But so much shouldalready b€ clear, that in every iudgement,G no matter how irivial, thesr€p fiom the level of thoughts to the level of B€dd"rrrg (the obiecrive)has aheady been taken.

One might be t€mpted to regard the relation of the thought to t}leTrue not as that of sense ro Bederflr?g, bur rather as tlat of subject topredicate. One can, indeed, say: 'The thouglt that 5 is a prime numberis true'. But closer examination shows that norling morc has been saidtlan in the simple sentence !5 is a prime number'. The truth claimarises in each case from dre form ofthe assertoric sentence, and whenthe latter lacks its usual force, e.g., in the mouth of an acror upon rhestage, even the sentence'The drought that 5 is a prime number is tlu€'contains only a thought, and indeed the same thoughr as rhe simple'5is a pime number'. It follows that the relarion of the rhoughr ro rhe Truemay not be compared with that of subject to predicate. Subj€ct andpredicate (understood in dre logical sense) are jusr elemenrs of rhoughrjthey stand on t}le same level for knowledge. By combining subject andpredicate, one reaches only a thought, never passes ftom a sense to irsBedeutung, ne'rer frcm a thoughr to its truth-value. One moves at lhesame level but never advanc€s from one level to the next. A tmd-valuecannot be a part of a thought, any morc rhan, say, the Sun canJ for itis not a sense but an object.

If our supposition that rhe Bede tung of ^

sentence is its truth-valueis correc{, the latter must r€main unchaneed when a pan of the sen-tence is replaced by an er,Tression with the same Bedeuruns. And. t\isis in fact the case.

er"ressing questions beginning wirh 'who', 'ivhar', '!vhere'! '!vhen', 'how','by what means', etc., seem at times to approximate verycloseiy to adver-bial clalses in which words have rheir cusromary Bcdrrr,?s. These cases

are distinglished linguistically [in Gennanl by the mood of rhe verb.With the subjunctivc, wc have a dcpendent question and t}le words havetheir indirect Bedeutung, so that a proper name cannot in general bercplaced by anothcr name of the same obiect.

In .he cas€s so far considered drc ivords of thc subordinatc clauses

had their indirect Bedertrr& and rhis madc it clear that thc Brdertd,aof rhe subordinate clause ilself was indirect, i.e. not a truth-valuc buta rhoughr, a command, a reques., a question. The subordinate clausecould be resarded as a noun, indeed one could say: as a propcr llameof that thought, rlat cornmand, etc., rvhich i. represented in the con-te)(t of the sentence structure.

',x/e now cofle to other subordinate clauses, in which the words dohave their customa{, Bedertrrg without however a thought occuning as

sense and a truth-valuc as Bede,r,,s'. How this is possible is best mad€clear bv examples.

''Whoever discovered &e eiiiplic fom oft\e pianerlry orbns dled iD miscry.'

If thc sensc of the subordinate clause were here a t1lought, it wouldhave to be possible to cxprcss it also in a separate sentence. But it doesnot work, bccausc the srammatical subject 'whoever' has no independ-cnt scnsc and only mcdiates d1e lelarioD with the consequent clause'dicd in miscry'. For dis rcason the sense of the subordinatc cl.ruse isnot a completc thought, and its Bcddrlrrng is Keplcr, not a tluth-v ue.

One might object that the sense of the wholc docs contain a thoughtas part, viz. that there was somebody who first discovered the ellipticfolm of the planetary orbits; for whoevc. takcs drc whole to be true I

cannor deny this pan. This is undoub.edly so; but only bccausc othcr-wise the dep€ndent clause 'whoever discovered rhe ciliptic form of thcplanetary orbirs' rvould hsve no Eedrrrrr?a. If anlthing is asserred thercis ahvays an obvious presupposition fiar Lhe simple or compound proper names used hav€ a Ardrrtrlrla. Iftherefore one assens 'Kepler diedin misery', there is a presupposition lhat the name 'Kepler' designatessomethingj but it does not follow that the sense ofrhe s€ntence'Keplerdied in misery' contains rle Gougii that the n3me 'Kepi€r' d€signatessomething. If this were the case the negation would have to run not

'Kcplcr did nor dic in miscry',

but

'Kerlcr did no! die in nriseryJ or thc nue Keplcr" is ,r/Lrtu,,fr1dl.

That the name 'Kepler' designates somerhing is jusr as much a presup-position for the assenion

'Kepler died in misery'

as for the conrary assetion. Now langlages have the fault ofcontain-ing expressions which fail to designate an object (although their gram-matical form seems to qualify them for thal purpose) because .he truthofsome sentence is a prerequisire. 1'hus it depends on the truth of the

And thus i. may appear as ifou. subordinatc clausc con-t.rined rs a pan of its sense the thought that there was somebody whodhcovered &e elliptic form of the plan€rary o$its.

the present tense of the verb, which in such a case horvever does notindicate the r€mporal present. This grrmmatical form is rhen the inde-6nite indicator in rhe main and subordinate clauses. An €xample ofthisisr '\{4len t}te Sun is in the trcpic of Cancer, the longesr &y in thenorthern hemispherc occurs'. Herej also, it is impossible to express thescnsc of the subordinare clause in a full scllence' because this sense is

not a complcte thoug'hi. Ifwe say'The Sun is in the tropic of Cancer',this would refer ro our present timerr and thereby change the sense.

Neither is the sense of the main clause a thought; only the whole, com-posed of main and subordinatc clauses, has such a sense. Ir may be addedthat several common components may be indefrnirely indicated in theantecedent and consequent clauscs.

It is ctear that noun clauses with 'who' or 'whaC ,nd adverbial clauses

with 'wherei 'when', 'wh€rever', 'whenever' are often to be interpreted as

havirg drc scnse ofrntecedent clauses, e-s. 'who touches pitch, defileshimself'.

Adjcctivc clauses can also rake the place ofconditional clauses.'fhusthe sense ofthe scntence previously used can be siven in the lorm "lh€square of a number which is less than I and grearer than 0 is lcss tlanI and greater than 0'.

The situarion is quite differenr if rlle common component of the twoclaus€s is d€signated by a proper name. Ill the sentence:

'Napoleon, who rccognized the danser to his right flank, himself led his

sud.ds ag,insr Lhe enemy posirion'

two thoughts are exprcssed:

\vllen and wherc this happened is to be fi,xed only by thc context, butis nevenheless to bc taken as definitely determined thereby. Ifthe entiresentence is ultered as an asscftion, we thereby simuhaneously asseftbothcomponent senrences. Ifone of the parts is false, rhe whole is false. Herewe have rhe case that thc subordinate clause by i.self has a completethougl. as sens€ (if we complcte it by indicalion of place and time).The Bedeurung of the subordinaic clause is accordingly a truth-valu€.wc can therelore expect thal it may be replaced, rvithout harm to thetruth-value ofthe rvhole, by a scntence having the I same tiuth-value.This is indeed the case; bur ir is to be noted that for purely grammalicalreasons, its subiect musr be 'Napoleon', for only then can it be broushtinto fic form of ltn rdjeclive clause attaching to 'Napoleon'. But ifthe

Subsidiary clauses beginning widr 'althoush' also cxpress complctethoughts. This contunction actually has no sense and does not changethe scnse ofthc clausc but only illuminates it in a p€culiar fashion.t Wecould indeed rcplace the concessive clause ivithout harm to rhe rruth ofllie whole by another ofthe same truth-valuej bur the lighr in $'hich theclause is placed by rhe conjuncrion might then easillr appear unsuirable,rs if a song with a sad subject were Io be sung in a lively fashion.

In the iast cas€s fie truth ofthe whole included dle truth of the com-ponent claus€s. The case is differcnt if an antecedcnt clausc expressesr complete though. by containing, in piace of an indefinite indicator,r proper name or something which is to bc regarded as equivalent. In

An examination ofall thc subodinare clauses which one may encoun-ter ivill soon providc some which do nor frt lvell into rhese caregories.The reason, so far as I can seeJ is thar rhese subordinate clauses haveno such simple s€nse. Almosr always, it seems, we conncct ivith themain thoughts exprcssed by us subsidiary rhoughrs which, alrhoush norexpressed, arc associared lviii our words, in accordance with psycho-iogic.l laws, by the hearer. And since the subsidiary rhought appears robe connected wirh our words on irs own accounr, almost like the mainthought its€lf, we want it also ro be e$resscd. The sense of rle sen-tence is lhereby enrichcd, and it may rvell happ rhar we have morcsimplc though$ rhan clauses. In many cases rhe scntence must be under-stood in lhis way, in othe$ ir may be doubttul whether the subsidiarythought belongs to the sense oflhe senrencc or only accompanies it.NOne mjght perhaps find rhar the scntcnc€

'^_apoleon, who recognizcd rhc dalser to his righr flank, himself ied hissuards asajnst ihe enemy posidon'

€xpresses not only rhe rwo *roughts sho$ryr above, but also the rhoughtthat the knowledse ofrhe d.nger was the reason why he led lhc suardsagainst thc encmy posirion. One may in fact doubr whethcr rhis rhoughtis tust slishtly suggesred or really exprcssed. Ler rhe question be con-sidered whether our sentence is false ifNapol€on's decision had alreadybeen nade before he recoelizcd the danger. If our sentence could betme in spite of rhisJ rhe subsidiary rhoughr should not be undersroodas pan of the sense. One lvould probably decide in favour of this. Thealtemative would make for a quite complicared situation: we should havemole simple thoughts than ciauses. If the senrcnce

'Napoieon recognizcd $e dangei to h; risht flaDk'

werc norv ro be replaced by another hving the same rrurh-value, e.g.

'Napoleon was dlr.ady nroie rhar 45 yea6 old',

not only would our first thought be changed, bul also our rhird one.Hencc the trulh-value of thc latter mighr change - viz. ifhis age was nor

dre reason for dle decision to lead the guards against the enemy. Thisshows why clauses of equal firth-value cannot always be substituted forone another in such cases. The clausc exp4sscs morc through its connection with another than it does in isolation.

kt us now consider cases where rhis rcgllarly happens. In the se ence

'Bebel fancies [@r/dt[ rhat the rctum of Alsace-Lonaine lvould lppeasctrance's desire for revetse'

two thoughts are expressed, which are not however shown by means ofantecedert and consequent clauses, viz.

(l) Bebel believes thlt dE retld of Alsace Lomine would .ppeaseFrance\ desire for revengei

(2) the retun ofAisace bnalne wouid not appease France's desire for

In the expression of the first thought, the words of lhe subordinateclaus€ have their indirect Bedeuung, .J'hile fi€ same words have fieircustomary Brdrrr#a in the expression of rhe second rhought. 'l-lxis showsfiat r}le subordinare clause in our original complex sentence is to beLaken twice over, wirh different Be.le tunsen, of which one is a thought,lhe other a rmth-value. Since the truth-value is not the whole Bedsrr{r,aoftie subordinate clause, we cannot simply replace the latter by anotherof equal rruth-value. Similar consideraiions apply to expressions suchrs 'know', 'recognize', 'it is wetl known'.r5

By means of a subordinrte causal clause and the associated mainclause rve express seveml thoughts, which however do not corrcspondseparately to the original clauses. In the sentencc 'Because ice is lcssdcnse than water, it floats on rvater' we have

(l) Ice is less dense than water;(2) If anythlng js le$ dense than warer, it floats on wrter;(l) lce fioars on warcr.

exprcsses our tust thought, as well as a pan of our second. This is how

it comes to pass that our subsidiary clause cannot be simply replaced

by anoths of equal trufi-value; for this would alt€r our second dloughtand ftereby might wel altet its sudl-value.

The situation is similar in dle sentence

'If hon were less dense than *€ter, it would float on water'. I

49 Here we have the two thoughts that iron is rot less dense than water,

and that something floats on water if it is less dense than water. Thesubsidiary clause again e:lTresses one thought and a part of the other.

If we interpret rhe sentence already considered,

'After Schleswig-Holst€in was sep.mted from Demark, Prussia and Aus-rria quarelled',

in such a way that it expresses the thought that Schleswig-Holstein was

once separared ftom Denrna*, we have fust ftis thought, and secondly

the rhought tlat, at a time more closely determined bv fie subordinate

clause, Prussia and Austria quanelled. Here also the subordinate clause

erTresses not only one thought but also a part of another' Therefore itmay not in general be rcplaced by another of the same truih-value.

It is hard to exhaust all the possibilities siven by languagej bur I hope

to have brought to light at least the essertial reasons why a subordin-ate clause may not alwa)s be replaced by another of equal truth-valuewithout halm to the truth of the whole sentence siructure. These rea-

the thought directly expressed by the subordinat€ clause, mak€s up rhesense of the whole senrence.

It follows with sufficient probability ftom rhe foregoing that the caseswhere a subordinate clause is nor replaceable by anorher of the samevalue cannot be brought in disproof of our view I that a ruth-value isthe Bed€&rrra of a sentence thar has a rhought as irs sense.

Irt us retum to our starting-poinr.Ifwe found'd = a' and'd = r'to have different cogritive values, rhe

explanation is that for the purpose ofacquiring knowledge, the s€nse ofthe sentence, viz., the thought e\<pressed by itr is no less relevant rhanits BedeuanE, i.e. its tudr-valu€. ffrow d = 4 then ]\deed 6e Bedeutunsof 'r' is the same as that of 'ai and hence the truth-value of 'a = ,' isthe same as that of 'a = a'. In spite of this, the sense of'r' may ditrerfrom the sense of'a', and thereby the thought expressed by rd

= ,' willdiffer ftom that expressed by 'd = a'. In that case the two sentences donot have the same cognitive value. Ifwe rmderstand by 'iudgement' theadvance ftom fie thought to its trurh-valueJ as in the present paper, wecan also say thar the judgements are different.
