Dependent places lujvo place struc= turedependent places In order = to understand which places, if any, should be completely removed from a luj= vo place structure, we need to understand the concept of dependent places. = One place of a brivla is said to be dependent on another if its value can b= e predicted from the values of one or more of the other places.

In other words, when the valu= e of the g1 place has been specified, the value of the g2 place is determin= ed by it. Conversely, since each dog has only one breed, but each breed con= tains many dogs, the g1 place is not dependent on the g2 place; if we know = only that some dog is a St. Bernard, we cannot tell by that fact alone whic= h dog is meant.

This type of problem becomes more evident when the subject of th= e sentence turns out not to exist: <anchor xml:id=3D"c15e1d9"/> - The King of Mexico didn't come to dinner. + The King of Mexico didn't come to dinner. <anchor xml:id=3D"c15e1d10"/> - The King of Mexico did come to dinner. + The King of Mexico did come to dinner.

The rest of this chapter is designed to explain the Lojban model= of negation.

bridi negation In discussing Lojban negation, we will call the form of logical = negation that simply denies the truth of a statement=20 bridi negation. Using bridi negation, we can say the eq= uivalent of=20 I haven't stopped beating my wife without implying that= I ever started, nor even that I have a wife, meaning simply=20 It isn't true that I have stopped beating my wife. Sinc= e Lojban uses bridi as smaller components of complex sentences, bridi negat= ion is permitted in these components as well at the sentence level. For the bridi negation of a sentence to be true, the sentence be= ing negated must be false. A major use of bridi negation is in making a neg= ative response to a yes/no question; such responses are usually contradicto= ry, denying the truth of the entire sentence. A negative answer to =20 <anchor xml:id=3D"c15e2d1"/> - Did you go to the store? + Did you go to the store? is taken as a negation of the entire sentence, equivalent to <anchor xml:id=3D"c15e2d2"/> - No, I didn't go to the store. + No, I didn't go to the store. The most important rule about bridi negation is that if a bridi = is true, its negation is false, and vice versa. The simplest way to express a bridi negation is to use the cmavo= =20 na of selma'o NA before the selbri of the affir= mative form of the bridi (but after the=20 cu, if there is one): <anchor xml:id=3D"c15e2d3"/>

Scalar Negation Let us now consider some other types of negation. For example, w= hen we say: <anchor xml:id=3D"c15e3d1"/> - The chair is not brown. + The chair is not brown. we make a positive inference - that the chair is some other colo= r. Thus, it is legitimate to respond: <anchor xml:id=3D"c15e3d2"/> - It is green. + It is green. Whether we agree that the chair is brown or not, the fact that t= he statement refers to color has significant effect on how we interpret som= e responses. If we hear the following exchange: <anchor xml:id=3D"c15e3d3"/> - The chair is not brown. - Correct. The chair is wooden. + The chair is not brown. + Correct. The chair is wooden. we immediately start to wonder about the unusual wood that isn't= brown. If we hear the exchange: <anchor xml:id=3D"c15e3d4"/> - Is the chair green? - No, it is in the kitchen. + Is the chair green? + No, it is in the kitchen. we are unsettled because the response seems to be a non-sequitur= . But since it might be true and it is a statement about the chair, one can= 't say it is entirely irrelevant! =20 What is going on in these statements is something called=20 scalar negation. As the name suggests, scalar negation = presumes an implied scale. A negation of this type not only states that one= scalar value is false, but implies that another value on the scale must be= true. This can easily lead to complications. The following exchange seems = reasonably natural (a little suspension of disbelief in such inane conversa= tion will help): <anchor xml:id=3D"c15e3d5"/> - That isn't a blue house. - Right! That is a green house. + That isn't a blue house. + Right! That is a green house. We have acknowledged a scalar negation by providing a correct va= lue which is another color in the set of colors permissible for houses. Whi= le a little less likely, the following exchange is also natural: <anchor xml:id=3D"c15e3d6"/> - That isn't a blue house. - Right! That is a blue car. + That isn't a blue house. + Right! That is a blue car. Again, we have acknowledged a scalar negation, and substituted a= different object in the universe of discourse of things that can be blue.<= /para> Now, if the following exchange occurs: <anchor xml:id=3D"c15e3d7"/> - That isn't a blue house. - Right! That is a green car. + That isn't a blue house. + Right! That is a green car. we find the result unsettling. This is because it seems that two= corrections have been applied when there is only one negation. Yet out of = context,=20 blue house and=20 green car seem to be reasonably equivalent units that s= hould be mutually replaceable in a sentence. It's just that we don't have a= clear way in English to say: <anchor xml:id=3D"c15e3d8"/> - That isn't a=20 - blue-house. + That isn't a=20 + blue-house. aloud so as to clearly imply that the scalar negation is affecti= ng the pair of words as a single unit. Another even more confusing example of scalar negation is to the= sentence: <anchor xml:id=3D"c15e3d9"/> - John didn't go to Paris from Rome. + John didn't go to Paris from Rome. Might=20 imply that John went to Par= is from somewhere else? Or did he go somewhere else from Rome? Or perhaps h= e didn't go anywhere at all: maybe someone else did, or maybe there was no = event of going whatsoever. One can devise circumstances where any one, two = or all three of these statements might be inferred by a listener. In English, we have a clear way of distinguishing scalar negatio= n from predicate negation that can be used in many situations. We can use t= he partial word=20 non- as a prefix. But this is not always considered goo= d usage, even though it would render many statements much clearer. For exam= ple, we can clearly distinguish <anchor xml:id=3D"c15e3d10"/> - That is a non-blue house. + That is a non-blue house. from the related sentence <anchor xml:id=3D"c15e3d11"/> - That is a blue non-house. + That is a blue non-house. - and=20 + and=20 have the advantage that, wh= ile they contain a negative indication, they are in fact positive assertion= s. They say what is true by excluding the false; they do not say what is fa= lse. We can't always use=20 non- though, because of the peculiarities of English's = grammar. It would sound strange to say: <anchor xml:id=3D"c15e3d12"/> - John went to non-Paris from Rome. + John went to non-Paris from Rome. or <anchor xml:id=3D"c15e3d13"/> - John went to Paris from non-Rome. + John went to Paris from non-Rome. although these would clarify the vague negation. Another circuml= ocution for English scalar negation is=20 other than, which works where=20 non- does not, but is wordier. Finally, we have natural language negations that are called pola= r negations, or opposites: <anchor xml:id=3D"c15e3d14"/> - John is moral + John is moral <anchor xml:id=3D"c15e3d15"/> - John is immoral + John is immoral To be immoral is much more than to just be not moral: it implies= the opposite condition. Statements like=20 are strong negations which = not only deny the truth of a statement, but assert its opposite. Since,=20 opposite implies a scale, polar negations are a special= variety of scalar negations.

Metalinguistic negation forms The question of truth or falsity is not entirely synonymous with= negation. Consider the English sentence <anchor xml:id=3D"c15e10d1"/> - I have not stopped beating my wife. + I have not stopped beating my wife. If I never started such a heinous activity, then this sentence i= s neither true nor false. Such a negation simply says that something is wro= ng with the non-negated statement. Generally, we then use either tone of vo= ice or else a correction to express a preferred true claim:=20 =20 I never have beaten my wife. Negations which follow such a pattern are called=20 metalinguistic negations. In natural languages, the mar= k of metalinguistic negation is that an indication of a correct statement a= lways, or almost always, follows the negation. Tone of voice or emphasis ma= y be further used to clarify the error. Negations of every sort must be expressible in Lojban; errors ar= e inherent to human thought, and are not excluded from the language. When s= uch negations are metalinguistic, we must separate them from logical claims= about the truth or falsity of the statement, as well as from scalar negati= ons which may not easily express (or imply) the preferred claim. Because Lo= jban allows concepts to be so freely combined in tanru, limits on what is p= lausible or not plausible tend to be harder to determine. Mimicking the muddled nature of natural language negation would = destroy this separation. Since Lojban does not use tone of voice, we need o= ther means to metalinguistically indicate what is wrong with a statement. W= hen the statement is entirely inappropriate, we need to be able to express = metalinguistic negation in a more non-specific fashion. =20 Here is a list of some different kinds of metalinguistic negatio= n with English-language examples: <anchor xml:id=3D"c15e10d2"/> - I have not=20 - stopped beating my wife - (I never started - failure of presupposition). + I have not=20 + stopped beating my wife + (I never started - failure of presupposition). <anchor xml:id=3D"c15e10d3"/> - 5 is not blue - (color does not apply to abstract concepts - failure of cate= gory). + 5 is not blue + (color does not apply to abstract concepts - failure of catego= ry). <anchor xml:id=3D"c15e10d4"/> - The current King of France is not bald. - (there is no current King of France - existential failure) - =20 + The current King of France is not bald. + (there is no current King of France - existential failure) + =20 <anchor xml:id=3D"c15e10d5"/> - I do not have THREE children. - (I have two - simple undue quantity) + I do not have THREE children. + (I have two - simple undue quantity) <anchor xml:id=3D"c15e10d6"/> - I have not held THREE jobs previously, but four. - (inaccurate quantity; the difference from the previous examp= le is that - someone who has held four jobs has also held three jobs) + I have not held THREE jobs previously, but four. + (inaccurate quantity; the difference from the previous example= is that + someone who has held four jobs has also held three jobs) <anchor xml:id=3D"c15e10d7"/> - It is not good, but bad. - (undue quantity negation indicating that the value on a - scale for measuring the predicate is incorrect) + It is not good, but bad. + (undue quantity negation indicating that the value on a + scale for measuring the predicate is incorrect) <anchor xml:id=3D"c15e10d8"/> - She is not PRETTY; she is beautiful. - (undue quantity transferred to a non-numeric scale) + She is not PRETTY; she is beautiful. + (undue quantity transferred to a non-numeric scale) <anchor xml:id=3D"c15e10d9"/> - The house is not blue, but green. - (the scale/category being used is incorrect, but a related c= ategory applies) + The house is not blue, but green. + (the scale/category being used is incorrect, but a related cat= egory applies) <anchor xml:id=3D"c15e10d10"/> - The house is not blue, but is colored. - (the scale/category being used is incorrect, but a broader c= ategory applies) + The house is not blue, but is colored. + (the scale/category being used is incorrect, but a broader cat= egory applies) <anchor xml:id=3D"c15e10d11"/> - The cat is not blue, but long-haired. - (the scale/category being used is incorrect, but an unrelate= d category applies) + The cat is not blue, but long-haired. + (the scale/category being used is incorrect, but an unrelated = category applies) <anchor xml:id=3D"c15e10d12"/> - A: He ain't coming today. - B:=20 - Ain't ain't a word. - (solecism, or improper grammatical action) + A: He ain't coming today. + B:=20 + Ain't ain't a word. + (solecism, or improper grammatical action) <anchor xml:id=3D"c15e10d13"/> - I haven't STOOPED beating my wife; I've STOPPED. - (spelling or mispronunciation error) + I haven't STOOPED beating my wife; I've STOPPED. + (spelling or mispronunciation error) <anchor xml:id=3D"c15e10d14"/> - Not only was it a sheep, it was a black sheep. - (non-contradictory correction) + Not only was it a sheep, it was a black sheep. + (non-contradictory correction) The set of possible metalinguistic errors is open-ended.

The chair is wooden. we immediately start to wonder about the unusual wood that isn't= brown. If we hear the exchange: - + <anchor xml:id=3D"c15e3d4"/> - - Is the chair green? - No, it is in the kitchen. - + Is the chair green? + No, it is in the kitchen. we are unsettled because the response seems to be a non-sequitur= . But since it might be true and it is a statement about the chair, one can= 't say it is entirely irrelevant! =20 What is going on in these statements is something called=20 scalar negation. As the name suggests, scalar negation = presumes an implied scale. A negation of this type not only states that one= scalar value is false, but implies that another value on the scale must be= true. This can easily lead to complications. The following exchange seems = reasonably natural (a little suspension of disbelief in such inane conversa= tion will help): - + <anchor xml:id=3D"c15e3d5"/> - - That isn't a blue house. - Right!

This is because it seems that two= corrections have been applied when there is only one negation. Yet out of = context,=20 blue house and=20 green car seem to be reasonably equivalent units that s= hould be mutually replaceable in a sentence. It's just that we don't have a= clear way in English to say: - + <anchor xml:id=3D"c15e3d8"/> - - That isn't a=20 - blue-house. - + That isn't a=20 + blue-house. aloud so as to clearly imply that the scalar negation is affecti= ng the pair of words as a single unit. Another even more confusing example of scalar negation is to the= sentence: - + <anchor xml:id=3D"c15e3d9"/> - - John didn't go to Paris from Rome. - + John didn't go to Paris from Rome. Might=20 imply that John went to Par= is from somewhere else? Or did he go somewhere else from Rome? Or perhaps h= e didn't go anywhere at all: maybe someone else did, or maybe there was no = event of going whatsoever. One can devise circumstances where any one, two = or all three of these statements might be inferred by a listener. In English, we have a clear way of distinguishing scalar negatio= n from predicate negation that can be used in many situations. We can use t= he partial word=20 non- as a prefix. But this is not always considered goo= d usage, even though it would render many statements much clearer. For exam= ple, we can clearly distinguish - + <anchor xml:id=3D"c15e3d10"/> - - That is a non-blue house. - + That is a non-blue house. from the related sentence - + <anchor xml:id=3D"c15e3d11"/> - - That is a blue non-house. - + That is a blue non-house. and=20 have the advantage that, wh= ile they contain a negative indication, they are in fact positive assertion= s. They say what is true by excluding the false; they do not say what is fa= lse. We can't always use=20 non- though, because of the peculiarities of English's = grammar. It would sound strange to say: - + <anchor xml:id=3D"c15e3d12"/> - - John went to non-Paris from Rome. - + John went to non-Paris from Rome. or - + <anchor xml:id=3D"c15e3d13"/> - - John went to Paris from non-Rome. - + John went to Paris from non-Rome. although these would clarify the vague negation. Another circuml= ocution for English scalar negation is=20 other than, which works where=20 non- does not, but is wordier. Finally, we have natural language negations that are called pola= r negations, or opposites: - + <anchor xml:id=3D"c15e3d14"/> - - John is moral - + John is moral - + <anchor xml:id=3D"c15e3d15"/> - - John is immoral - + John is immoral To be immoral is much more than to just be not moral: it implies= the opposite condition. Statements like=20 are strong negations which = not only deny the truth of a statement, but assert its opposite. Since,=20 opposite implies a scale, polar negations are a special= variety of scalar negations.
