3 Polar Opposition and the Ontology of Comparison The objective of this chapter is to demonstrate that degrees should be formalized as intervals on a scale rather than as points, as traditionally assumed. Using cross-polar anomaly as the empirical basis for my claims, I will argue that gradable adjectives denote functions from objects to intervals on a scale, or extents, and assume an ontology which distinguishes between two sorts of extents: positive extents and negative extents (as in Seuren 1978, von Stechow 1984b, and Löbner 1990). I characterize the difference between positive and negative adjectives as a sortal one: positive adjectives denote functions from objects to positive extents, and negative adjectives denote functions from objects to negative extents. After setting this analysis into the semantic framework developed in chapter 2, I show that cross-polar anomaly can be explained in the same way as incommensurability: a consequence of the sortal characterization of adjectival polarity is that the ranges of positive and negative adjectives are disjoint; as a result, the comparison relation in examples of cross-polar anomaly is undefined. Section 3.2 continues with an examination of comparison of deviation constructions, which at first glance appear to be counterexamples to the proposals made in section 3.1, but upon closer examination turn out to fit in naturally with the analysis of degree constructions developed in chapter 2. Finally, section 3.3 demonstrates that the algebra of extents, in conjunction with the semantic analysis of gradable adjectives as measure phrases, has the additional positive result of providing the basis for an insightful explanation of the monotonicity properties of gradable adjectives. 3.1 Comparison and Polar Opposition 3.1.1 The Algebra of Degrees The semantic analysis of gradable adjectives and degree constructions developed in chapter 2 characterized the interpretations of these expressions in terms of abstract degrees, or points on a scale. The notion of a degree as a point on a scale goes back at least to Cresswell (1976), 187 who suggests that “[w]hen we make comparisons we have in mind points on a scale” (p. 266). Cresswell builds an algebra of degrees directly from the domain of the adjective; in chapter 2 (see section 2.1.3), I adopted a modified version of this approach, in which scales and degrees are defined abstractly in terms of a linearly ordered set of points and a dimension. Specifically, I defined a scale S δ as a dense, linearly ordered set of points along a dimension δ, and a degree as an element of the scale. Within this sort of ontology, gradable adjectives are traditionally analyzed as two place relations between degrees and individuals. In chapter 2 however, I argued for an alternative approach to the semantics of gradable adjectives in which they are analyzed as measure functions–functions from objects to degrees. Although this approach, as well as the semantics of degree constructions built on top of it, differed from the traditional analysis in a number of important respects, it nevertheless maintained the traditional assumptions about the basic structure of scales and degrees. In the following sections, I will take a closer look at these assumptions, focusing on the representation of adjectival polarity within a degree algebra. In section 3.1.3, I will turn to an examination of cross-polar anomaly, where I will demonstrate that an algebra of degrees that characterizes these objects as points on a scale incorrectly predicts that comparatives constructed out of antonymous pairs of adjectives should be perfectly interpretable. 3.1.2 Degrees and Polar Opposition As observed in chapter 1 (see section 1.1.4), a characteristic of many (though not all) gradable adjectives is that they come in pairs: tall - short, safe - dangerous, sharp - dull, bright - dim, etc. In a basic sense, the meanings of the members of such antonymous pairs are fundamentally the same: they apply to the same objects, and they provide the same kind of information about the degree to which an object possess some gradable property. The antonymous adjectives tall and short, for example, both provide information about an object’s height. At the same time, positive and negative adjectives represent different–and in some sense complementary–perspectives on the degree to which an object possesses a gradable 188

Th

e seman

characterized th

s of these expression

he n

resswell (19

187

wh

o suggests th

at “[w]h

266

). Cressw

ell builds an

algebra of degrees directly from th

of the adjective; in

chapter 2 (see section

2.1.3), I adopted a modified version

of this approach

, in w

ed a scale Sδ as a den

With

As observed in

chapter 1 (see section

1.1.4), a characteristic of m

any (th

ough

not all) gradable

adjectives is that th

ey come in

pairs: tall - short, safe - dangerous, sharp - dull, bright - dim, etc.

In a basic sen

se, the m

adjectives tall and short, for exam

about an

Th

Alth

ltimately con

struct an

explanation

of cross-polar anom

terms, th

does not appear to be available w

the tradition

of the in

comm

ensu

d (26)

presupposes th

at the scales associated w

ith th

e adjectives clever and tall are distin

ct (i.e., they

are associated with

different dim

ension

al parameters; see th

e discussion

in ch

apter 1,

section 1.1.3). T

his is cru

show

In order for an

surability explan

ation of cross-polar an

rough

,

then

, it mu

st be demon

strated that for an

y for anton

o

mappin

g between

objects in th

e range of th

e positive adjective and objects in

the ran

the n

a mappin

g can be defin

ed, then

examples like (15)-(18) sh

ould be

amen

able to the sam

e sort of analysis as (19

) and (20

). Th

e problem is th

at it mu

case that a m

Alth

ough

it fails to explain cross-polar an

e proposal that positive an

surable con

tains an

g hypoth

esis: that degrees of talln

and degrees of sh

t sorts of objects, with

the con

sequen

ce that th

of a positive adjective is disjoint from

the ran

ge of its negative cou

is were th

e

case, then

cross-polar anom

aly could be explain

ed in th

e same term

s as incom

surability:

it wou

ate the relation

With

out an

ad hoc stipu

lation to th

is effect, how

ever, there is n

o way to bu

ild the n

ecessary

sortal difference betw

een p

ositive and n

egative degrees into a degree algebra: if

correspondin

g positive and n

egative degrees on th

e same scale den

ote the sam

e objects,

then

they are sortally in

distingu

ishable from

one an

other. In

the follow

ing section

, I will

develop an altern

ative algebra of degrees in w

hich

positive and n

egative degrees are analyzed

as distinct objects, an

d I will sh

ow th

at this distin

ction n

ot only provides an

insigh

tful

representation

of adjectival polarity and an

accoun

t of the validity of statem

ents like (14), it

also provides the basis for an explan

ation of cross-polar an

omaly.

3.1.5 The A

lgebra of Exten

ts

In order to develop a solu

tion to th

e problem of cross-polar an

omaly, I w

ill adopt an on

tology

of comparison

in w

hich

the projection

of an object on

a scale is represented n

ot as a discrete

point, bu

t rather as an

interval, wh

ich I w

ill refer to as an extent (cf. S

euren

1978, 19

84, von

Stech

ow 19

84

b, Bierw

isch 19

89

, Löbner 19

90

). In term

s of the an

alysis of gradable

adjectives developed here, th

e basic claim rem

ains th

e same: every gradable adjective

denotes a fu

nction

from objects to scalar valu

es, and scales are differen

tiated throu

gh

association w

ith a dim

ension

. Th

e difference is in

the stru

cture of th

e scalar values–w

hat I

have referred to u

p to now

as “degrees”. Wh

ereas the algebra of degrees ou

tlined in

section

3.1.2 represents scalar valu

es as a discrete points, th

e extent algebra th

at I will form

alize

199

199

below represen

ts degrees as intervals. A

s I will dem

onstrate, th

is modification

provides the

basis for an an

alysis of adjectival polarity wh

ich both

predicts the validity of statem

ents like

(14) above and supports an

explanation

of cross-polar anom

aly.

In term

s of basic structu

re, the n

otion of a scale can

be formalized as above.

Specifically, let a scale Sδ be a den

se, linearly ordered set of poin

ts along a dim

ension

δ which

may h

ave a min

imal elem

ent bu

t has n

o maxim

al elemen

t. 8 Since a scale is defin

ed as a sets

of points, an

extent on a scale can

be defined as a n

onem

pty, convex su

bset of the scale, i.e. a

subset of S

δ with

the follow

ing property: ∀

p1 ,p

2 ∈E∀

p3 ∈

Sδ [p

1 <p

3 <p

2 → p

3 ∈E

] (cf. Landm

an

199

1:110; th

is is simply th

e definition

of an in

terval for a linearly ordered set of poin

ts).

Fin

ally, I will defin

e a proper extent on a scale S

δ as a non

empty, con

vex proper subset of S

δ .

Th

e distinction

between

extents an

d proper extents n

ot crucial, rath

er it is made prim

arily to

simplify th

e definition

s of positive and n

egative extents presen

ted below, an

d to avoid the

question

of wh

at sort of extent th

e scale itself is.

Th

ese definition

s provide the basis for a sem

antic an

alysis of gradable adjectives as

fun

ctions from

individu

als to extents th

at has essen

tially the sam

e properties as the degree-

based analysis assu

med u

p to now

. In order to bu

ild a foun

dation for an

alternative th

eory of

adjectival polarity, I will m

ake a furth

er distinction

between

two sorts of exten

ts–positive

extents and negative extents–w

hich

are defined in

(28) and (29

).

(28)

A positive extent on

a scale is a proper extent w

hich

ranges from

the low

er end of th

e

scale to some positive poin

t.

(29)

A negative extent on

a scale is a proper extent w

hich

ranges from

some positive poin

t

to the u

pper end of th

e scale.

8Alth

ough

it seems appropriate to assu

me th

at the scales associated w

ith dim

ension

al

adjectives like long an

d wide h

ave a min

imal elem

ent, it is n

ot obvious th

at the sam

e holds of

adjectives like beautifu

l and creative. S

ince th

is point does n

ot affect the basic claim

s to be made

below, I h

ave left the qu

heth

er scales have a m

Given

these backgrou

s, we can

now

constru

ct a formal an

alysis of

adjectival polarity in term

s of an algebra of exten

ts. In section

3.1.2, I noted th

e followin

g

distinction

between

anton

ymou

s pairs of adjectives: althou

gh th

e mem

bers of a positive and

negative pair of adjectives m

easure objects accordin

g to the sam

e dimen

sion, th

ey represent

complem

entary perspectives on

the projection

of an object on

ple, the

d Mike is short both

provide inform

t the h

Carm

t the in

is qualitatively differen

the positive adjective tall con

object has, w

hile th

e

negative adjective short con

veys inform

ation abou

t the h

object does not h

Stech

201

Th

e distinction

between

positive and n

e algebra of

extents–

specifically,

the

comp

lemen

tarity illu

strated

in

(32)–p

rovides

a m

eans

of

representin

g adjectival polarity in a w

ay that captu

res these in

tuition

s. Specifically, I w

ill

claim th

at positive adjectives denote fu

nction

s from objects to positive exten

ts, and n

egative

adjectives denote fu

nction

s from objects to n

egative extents. P

ut an

other w

ay, I am claim

ing

that adjectival polarity is a sortal distin

ction betw

een positive an

d negative adjectives. A

ll

gradable adjectives denote fu

nction

s from objects to exten

ts, but th

e set of such

fun

ctions

can be sorted accordin

g to their ran

ge: positive adjectives denote gradable properties w

hose

range is th

e set of positive extents on

a scale S; n

egative adjectives denote gradable

properties wh

ose range is th

e set of negative exten

ts on S

. A con

sequen

ce of this approach

is that alth

ough

anton

ymou

s pairs of positive and n

egative adjectives define m

appings from

objects in th

eir domain

s to the sam

e scale, the positive projection

of an object on

a scale is

distinct from

the n

egative projection of th

at object on th

e same scale.

Th

is distinction

represents th

e fun

damen

tal difference betw

een th

is approach to

adjectival polarity and th

e one provided by th

e degree algebra outlin

ed in section

3.1.2: in th

e

former, bu

t not th

e latter, the ran

ges of a positive and n

egative pair of adjectives are disjoint.

As observed in

section 3.1.2, becau

se degrees are defined as poin

ts on a scale, th

ere is no w

ay

to differentiate positive an

d negative degrees. If gradable adjectives den

ote fun

ctions from

objects to points on

a scale, then

for any object a an

d any pair of positive an

d negative

adjectives ϕpos an

d ϕneg , ϕ

pos (a) and ϕ

neg (a) denote th

e same object. In

contrast, exten

ts have

additional stru

cture, n

amely th

e intervals exten

ding to th

e relevant en

d of the scale. A

s a

result, positive an

d negative exten

ts are distinct objects, an

d for any object a an

d any pair of

positive and n

egative adjectives ϕpos an

d ϕneg , ϕ

pos (a) ≠ ϕneg (a). P

ut an

other w

ay, positive and

negative exten

ts are different sorts of objects, distin

guish

ed in term

s of perspective. A

consequ

ence of th

is distinction

is that, for an

S an

d

the set of n

Th

the claim

that th

correspond to (30

) and (31), repeated below

follows:

(52)–

neg

δ (x) = posδ (x) - {d(x)}

(53)–

posδ (x) = n

Retu

rewrite (51) as th

(54)

If posδ (a) > po

investigated th

e possibility of an explan

ation of th

terms

of incom

surability. T

he basic idea beh

ind th

is type of explanation

is that degrees of e.g.

tallness and shortness, like degrees of e.g. tallness an

d cleverness, shou

ld be analyzed as distin

ct

objects in differen

t ordered sets. If this w

ere the case, th

en th

troduced by th

e

comparative m

orphem

e wou

ld be un

defined, an

d cross-polar anom

aly could be explain

ed in

the sam

e way as in

comm

ensu

rability. I observed that th

is explanation

is un

available if

degrees are defined as poin

ts on a scale, becau

se the algebra of degrees does n

ot make a

distinction

between

positive and n

egative degrees: for any scale, th

e set of positive degrees

and th

e set of negative degrees are isom

orphic. A

s a result, an

y expression w

hich

is a

substitu

tion in

stance of (23) or (24) (repeated below

e crucial con

sequen

ce of these assu

mption

s

is that th

e range of a positive adjective is disjoin

e range of its n

egative coun

terpart.

If the sets of positive an

the com

ed. Cross-polar an

us a m

ore general

phen

on th

an th

e original facts su

ggest: it does not requ

ire that th

e two adjectives in

the com

bers of a specific positive-negative pair, on

ly that th

ey are of

deed, the an

alysis proposed here predicts th

at this sh

ould be th

e case.

To su

mm

arize, the explan

because th

e algebra of extents perm

its a sortal distinction

between

positive and n

ade at a very basic, structu

ral level. More im

portantly, th

e fact that th

e hypoth

esis that “degrees”

shou

ld be characterized as in

tervals on a scale, rath

er than

as points on

polarity is represented as a sortal distin

we predict th

ately, the cru

the distin

3.1.8 The D

easure Phrases

As observed by von

Stech

ow (19

84b), the algebra of exten

ation for

211211

the con

trast between

examples like (6

6) an

d (67).

(66

)M

y Cadillac is 8 feet lon

#My F

If we assu

me th

at measu

re phrases den

ote boun

ded extents (see th

e discussion

of

comparison

of deviation in

section 3.2), an

d that dim

ension

al adjectives such

as long, tall, and

wide are associated w

ith scales w

ith a m

inim

al elemen

t, then

this con

trast can be explain

ed

in th

e same w

ay as cross-polar anom

aly: the orderin

g relation in

troduced by th

e absolute

morph

eme is u

ndefin

ed in (6

7) but n

ot in (6

6).

Th

e explanation

run

s as follows. If th

e scale of length

has a m

inim

al elemen

t, then

according to th

e definition

s of scales and positive an

d negative exten

ts in section

3.1.5,

positive extents on

the scale of len

gth are bou

nded bu

t negative exten

ts on th

e scale of

length

are not (becau

se scales have n

o maxim

t). It follows th

at the objects in

the

range of long are th

e sort of extents th

at can be referred to by a m

easure ph

rase, but objects

in th

e range of short are n

ot. It follows th

at the logical represen

tation of (6

6), sh

own

in (6

8),

is interpretable, becau

se the partial orderin

g between

the positive exten

t of my C

adillac’s

longn

ess and th

e extent den

oted by 8 feet is defined.

(68

)abs(long(m

y Cadillac))(8 feet)

In con

trast, since th

e negative exten

t of my F

iat’s shortn

ess and th

e boun

ded extent

denoted by 4 feet are objects in

disjoint sets, th

e ordering in

troduced by th

e absolute in

the

logical representation

of (67), sh

own

below in

(69

ed.

(69

)abs(short(m

212212

Becau

se the orderin

defined, (6

If this an

it suggests an

explanation

for the fact th

anom

alous, (70

(70)

My fiat is sh

orter than

Stru

cturally, (70

presented in

of (70) sh

ould be (71).

Th

e crucial differen

at the stan

the latter is

provided directly by the m

easure ph

rase, wh

ile the stan

dard value in

er is derived by

applying th

that th

e result of th

is

operation is th

e negative exten

t that ran

ges from th

the scale correspon

ding to 5

we w

here

they are

Th

is is particularly clear in

Con

Assu

of deviation in

volves comparison

of such

“differential exten

of deviation in

terpretation of (8

involves a relation

between

e1 and e2 in

(95). B

uildin

g on th

e standard in

terpretation of th

of deviation in

terpretation of (84) can

be characterized as in

(97):

(97)

||(84)|| = 1 iff e1 ≥e2 , w

here e1 •stall = tall(w

Note th

at in order to evalu

ate the orderin

14Som

e kind of con

“differential” com

Th

to the set of positive an

15Th

is assum

tails that for an

e

goal of this section

is to show

that th

otonicity properties of polar adjectives follow

directly from th

e theory of polarity developed in

section 3.1, in

wh

ich polar adjectives are

sorted according to th

3.3.2 Degrees an

Recall from

the discu

ssion in

section 3.1 th

at logical polarity (in th

e sense discu

ssed above) is

represented in

a degree algebra as a distinction

in th

e range of gradable adjectives. A

s

defined above, a scale S

δ is a linearly ordered set of degrees alon

g some dim

ension

. If we

227227

assum

e that a positive adjective preserves th

e order on S

δ , wh

ile a negative on

e reverses it,

then

for any scale S

δ and an

y pair of positive and n

egative adjectives associated with

Sδ , th

e

set of degrees associated with

the positive D

pos and th

e set of degrees associated with

the

negative D

neg stan

d in th

e dual relation

. Dpos an

d Dn

eg are differentiated by orderin

g, but

their m

embersh

ip is the sam

e. Moreover, sin

ce there is a on

e-to-one m

apping betw

een th

e

two sets (th

e identity fu

nction

), Dpos an

d Dn

eg are isomorph

ic. A positive resu

lt of this

analysis is th

at it predicts that statem

from th
