Th
e objective of this ch
apter is to demon
strate that degrees sh
ould be form
alized as
intervals on
a scale rather th
an as poin
ts, as traditionally assu
med. U
sing cross-polar

pirical basis for my claim
s, I will argu
e that gradable adjectives den
ote
fun
ctions from
objects to intervals on
a scale, or extents, an
d assum
e an on
tology wh
ich
distingu
ishes betw
een tw
o sorts of extents: positive exten
ts and n
egative extents (as in

0). I ch
aracterize the differen
ce
between
positive and n
egative adjectives as a sortal one: positive adjectives den
ote fun
ctions
from objects to positive exten
ts, and n
egative adjectives denote fu
nction
s from objects to
negative exten
ts. After settin
g this an
alysis into th

ork developed in
chap
ter 2, I show
that cross-p

lained in
the sam
e way as
incom
men
surability: a con
sequen
ce of the sortal ch
aracterization of adjectival polarity is th
at
the ran
ges of positive and n
egative adjectives are disjoint; as a resu
lt, the com
parison relation
in exam

3.1.1 The A
lgebra of Degrees
Th
e seman
tic analysis of gradable adjectives an
d degree constru
ctions developed in
chapter 2
characterized th
e interpretation
s of these expression
s in term
s of abstract degrees, or points
on a scale. T
he n
otion of a degree as a poin
t on a scale goes back at least to C
resswell (19
76),
187
wh
o suggests th
at “[w]h
en w
e make com
parisons w
e have in
min
d points on
a scale” (p.
266
). Cressw
ell builds an
algebra of degrees directly from th
e domain
of the adjective; in
chapter 2 (see section
2.1.3), I adopted a modified version
of this approach
, in w
hich
scales
and degrees are defin
ed abstractly in term
s of a linearly ordered set of poin
ts and a
dimen
sion. Specifically, I defin
ed a scale Sδ as a den
se, linearly ordered set of poin
ts along a
dimen
sion δ, an
d a degree as an elem
ent of th
e scale.
With
in th
is sort of ontology, gradable adjectives are tradition
ally analyzed as tw
o place
relations betw
een degrees an
d individu
als. In ch
apter 2 how
ever, I argued for an
alternative
approach to th
e seman
tics of gradable adjectives in w
hich
they are an
alyzed as measu
re
fun
ctions–
fun
ctions from
objects to degrees. Alth
ough
this approach
, as well as th
e
seman
tics of degree constru
ctions bu
ilt on top of it, differed from
the tradition
al analysis in
a nu
mber of im
portant respects, it n
evertheless m
aintain
ed the tradition
al assum
ptions
about th
e basic structu
re of scales and degrees. In
the follow
ing section
s, I will take a closer
look at these assu
mption
s, focusin
g on th
e representation
of adjectival polarity with
in a
degree algebra. In section
3.1.3, I will tu
rn to an
examin
ation of cross-polar an
omaly, w
here I
will dem
onstrate th
at an algebra of degrees th
at characterizes th
ese objects as points on
a
scale incorrectly predicts th
at comparatives con
structed ou
t of anton
ymou
s pairs of
adjectives shou
ld be perfectly interpretable.
3.1.2 Degrees an
d Polar O
pposition
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
eanin
gs of the m
embers of su
ch an
tonym
ous pairs are fu
ndam
entally
the sam
e: they apply to th
e same objects, an
d they provide th
e same kin
d of inform
ation
about th
e degree to wh
ich an
object possess some gradable property. T
he an
tonym
ous
adjectives tall and short, for exam
ple, both provide in
formation
about an
object’s heigh
t. At
the sam
e time, positive an
d negative adjectives represen
t different–
and in
some sen
se
complem
entary–
perspectives on th
e degree to wh
ich an
object possesses a gradable
188
property. Intu
itively, tall measu
res the h
eight an
object has; short m
easures th
e heigh
t an
object does not h
ave.
Th
e empirical m
anifestation
of this distin
ction in
perspective can be observed in
differences in
the in
terpretations of absolu
te and com
parative constru
ctions w
ith positive
and n
egative adjectives. Th
e basic analysis of th
e seman
tics of positive adjectives can be
illustrated by con
sidering in
terpretation of (1). T
he logical form
of (1) is (2), wh
ere slong
denotes a stan
dard of longn
ess relative to some com
parison property appropriate for T

Th
e relational differen
ces between
positive and n
egative adjectives illustrated by
these exam
ples suggest a m
eans of form
ally representin
g adjectival polarity with
in th
e
algebra of degrees outlin
ed in section
3.1.1. As n
oted above, the m
embers of a positive an
d
negative pair of gradable adjectives n
ot only apply to th
e same objects (i.e., sh
are the sam
e
191
domain
), they also provide th
e same basic in
formation
about th
e objects to wh
ich th
ey apply:
they m
easure th
e degree to wh
ich an
object possesses some gradable property. A
noth
er
way of statin
g this observation
is that positive an
d negative pairs of adjectives m
easure
objects according to th
e same dim
ension
. Th
e crucial differen
ce between
positive and
negative adjectives, illu
strated by the exam
ples discussed above, is th
at the m
easurem
ents
they retu
rn perm
it complem

ost clearly

he Brothers K
aramazov “exceeds” T
he

respect to longn
ess, The Idiot “exceeds” T
he Brothers K
aramazov w
ith respect to

Th
e analysis of gradable adjectives as m
easure fu
nction
s sup
ports a form
al
representation
of adjectival polarity wh
ich captu
res the in
tuition
s about polar adjectives
outlin
ed here. T
he claim
that gradable adjectives den
ote measu
re fun
ctions is a claim
about
their sem
antic type: th
ey denote fu
nction
s from objects to degrees. P
ut an
other w
ay, the
range of a gradable adjective is a scale. S
ince scales are defin
ed as a linearly ordered set of
degrees along som
e dimen
sion (w
hich
corresponds to a gradable property su
ch as length or
density), w
e can captu
re the in
tuition
that positive an
d negative pairs of adjectives m
easure
objects according to th
e same dim
ension
by assum
ing th
at they defin
e identical m
appings
from th
e objects in th
eir domain
s to points on
a shared scale. T
o make th
is idea more
precise, I will assu
me th
e general prin
ciple in (13) (cf. R
ullm
ann
199
5).

ith dim
ension
al parameter δ, an
d for any object x in
the dom
ain of ϕ
pos
and ϕ
neg : ϕpos (x) = ϕ
neg (x).
Th
e crucial differen
ce between
ϕp
os and ϕ
neg –
wh
at I referred to as a difference in
perspective–is that th
ey impose opposite orderin
gs on th
eir domain
s. Th
is difference can
be
represented in
terms of an
ordering distin
ction betw
een th
e ranges of ϕ
pos an
d ϕneg .
192
Specifically, I w
ill assum
e that th
e range of th
e positive is the set of degrees on
the scale
un
der the basic orderin
g provided by the scale (“<“), w
hile th
e range of th
e negative th
e set
of degrees on th
e scale un
der the reverse orderin
g (“>”). On
this view
, a negative adjective is
the du
al of its positive coun
terpart (cf. Cressw
ell 1976
, Gaw
ron 19
95, S
ánch
ez-Valen
cia
199
5, Ru
llman
n 19
95).
Th
e claim u
nderlyin
g this represen
tation of adjectival polarity is th
at positive and
negative pairs of adjectives m
ap the objects in
their dom
ains to degrees on
the sam
e basic
scale, but th
eir ranges are differen
tiated by virtue of bein
g associated with
opposite ordering
relations. S
ince th
ere is a one-to-on
e mappin
g between
the ran
ge of ϕpos an
d the ran
ge of
ϕneg (th
e identity fu
nction
), how
ever, the tw
o sets are isomorph
ic. In oth
er words, for an

scale S, th
e set of positive degrees on S
and th
e set of negative degrees on
S con
tain th
e
same objects. T
his h
as a very importan

Th

al

that T

ccording to th
e analysis of adjectival
polarity outlin
ed in section
3.1.2, the adjectives long and short defin
e the sam
e mappin
g from
the objects in
their dom

s that degrees of longness

erefore the com

not on

the ran

t also
the m

thou

Th

such
that C

Th

resultin

Alth
ough
I will u
ltimately con
struct an
explanation
of cross-polar anom
aly in th
ese
terms, th
is type of explanation
does not appear to be available w
ithin
the tradition
al degree
algebra. Th
e explanation
of the in
comm
ensu
rability of examples like (25) an
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
cial to the explan
ation, becau
se wh
en th
e adjectives in a su
bdeletion
structu
re map th
eir argum
ents to poin
ts on th
e same scale, com
parison is possible, as
show
n by th
e examples discu
ssed above.
In order for an
incom
men
surability explan
ation of cross-polar an
omaly to go th
rough
,
then
, it mu
st be demon
strated that for an
y for anton
ymou
s pair of adjectives, there is n
o
mappin
g between
objects in th
e range of th
e positive adjective and objects in
the ran
ge of
the n
egative. If such
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
st be the
case that a m
apping betw
een e.g. degrees of talln
ess and degrees of sh
ortness can
be
defined, oth
erwise th
e validity of (14) wou
ld remain
un
explained (see R
ullm
ann
199
5 for
additional discu
ssion of th
is point). T
he in
comm
ensu
rability explanation
fails because an
y
algebra of degrees wh
ich explain
s the validity of con
struction
s like (14)–wh
ich is a m
inim
al
requirem
ent of descriptive adequ
acy–shou
ld also permit a m
apping betw
een positive an
d
negative degrees, w
ith th
e consequ
ence th
at examples of cross-polar an
omaly sh
ould be fu
lly
198
198
interpretable.
Alth
ough
it fails to explain cross-polar an
omaly, th
e proposal that positive an
d negative
adjectives are incom
men
surable con
tains an
interestin
g hypoth
esis: that degrees of talln
ess
and degrees of sh
ortness are differen
t sorts of objects, with
the con
sequen
ce that th
e range
of a positive adjective is disjoint from
the ran
ge of its negative cou
nterpart. If th
is were th
e
case, then
cross-polar anom
aly could be explain
ed in th
e same term
s as incom
men
surability:
it wou
ld be impossible to evalu
ate the relation
introdu
ced by the com
parative morph
eme.
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
estion of w
heth
er scales have a m
inim
al elemen
t open.
200
200
To m
ake thin
gs more precise, assu
me th
at for any object a w
hich
can be ordered accordin
g
to some dim
ension
δ, there is a fu
nction
d from a to a u
niqu
e point on
the scale S
δ . 9 Let
the positive exten
t of a on S
δ (posδ (a)) be as defin
ed in (30
), and let th
e negative exten
t of a
on S
δ (neg
δ (a)) be as defined in
(31).
(30)
posδ (a) = {p ∈
Sδ | p ≤ d(a)}
(31)n
egδ (a) = {p ∈
Sδ | d(a) ≤ p}.
Accordin
g to the defin
itions in
(30) an
d (31), the positive an
d negative projection
s of an
object on a scale are (join
) complem
entary. T
his is illu
strated by (32), wh
ich sh
ows th
e
positive and n
egative extents of an
object a on th
e scale Sδ .

Given
these backgrou
nd assu
mption
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
to scale. For exam
ple, the
senten
ces Carm
en is tall an
d Mike is short both
provide inform
ation abou
t the h
eight of
Carm
en an
d Mike, respectively, bu
t the in
formation
is qualitatively differen
t in each
case:
the positive adjective tall con
veys inform
ation abou
t the h
eight an
object has, w
hile th
e
negative adjective short con
veys inform
ation abou
t the h
eight an
object does not h
ave (cf. von
Stech
ow 19
84b:196
).

201

Th
e distinction
between
positive and n
egative extents provided by th
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
y scale S, th
e set of positive extents on
S an
d
the set of n
egative extents on
S are disjoin
t subsets of th
e total set of extents on
S. T
his
aspect of the exten
t algebra provides the fou
ndation
for the explan
ation of cross-polar
202

anom
aly that I w
ill present in
section 3.1.7.
Th

Th

nam

(50) can
be paraphrased in
the follow
ing w
ay: “the exten

the exten

aramazov is sh

ly if the exten

ich T

ich T

ore generally,
206
206
statemen
ts like (50) can
be viewed as su
bstitution
instan
ces of (51), wh
ere ϕpos an
d ϕneg are
anton
ymou
s gradable adjectives.
(51)ϕ
pos (a) > ϕpos (b) iff ϕ
neg (b) > ϕn
eg (a)
Th
e validity of (51) follows from
the claim
that th
e positive and n
egative projections of an
object on a scale are join
complem
entary. In
section 3.1.4, I claim
ed that th
e positive and
negative projection
s of an object on
to a scale along dim
ension
δ, posδ (a) an
d neg
δ (a),
correspond to (30
) and (31), repeated below
, wh
ere d is a fun
ction from
an object to a poin
t
on th
e scale.
(30)
posδ (a) = {p ∈
Sδ | p ≤ d(a)}
(31)n
egδ (a) = {p ∈
Sδ | d(a) ≤ p}
From
these defin
itions, w
e can defin
e the com
plemen
ts of positive and n
egative extents as
follows:
(52)–
neg
δ (x) = posδ (x) - {d(x)}
(53)–
posδ (x) = n
egδ (x) - {d(x)}
Retu
rnin
g to (51), since th
e result of applyin
g ϕpos an
d ϕneg to an
object is a positive or
negative exten
ts on th
e scale shared by ϕ
pos and ϕ
neg , we can
rewrite (51) as th
e more gen
eral
statemen
t in (54), an
d use th
e equivalen
ces in (52) an
d (53) to prove its validity.
(54)
posδ (a) > po
sδ (b) iff neg
δ (b) > neg
δ (a)
If posδ (a) > po
sδ (b), then
posδ (a) - {d(a)} > po
sδ (b) - {d(b)}, since d(a) an
d d(b) are the
207
207
maxim
al elemen
ts of pos(a) an
d pos(b), respectively. It follow
s that –
neg
δ (a) > –neg
δ (b),
by substitu
tion, an
d finally th
at neg
δ (b) > neg
δ (a), by contraposition
. Th
e other direction
of
the bicon
ditional can
be proved in exactly th
e same w
ay.
3.1.7 Cross-P
olar An
omaly R
evisited
We are n
ow in
a position to explain
cross-polar anom
aly. Recall th
at in section
3.1.3 I
investigated th
e possibility of an explan
ation of th
is anom
aly with
in a degree algebra in
terms
of incom
men
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
e relation in
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
), wh
ich sch
ematically represen
t the
interpretation
of examples of cross-polar an
omaly, sh
ould be perfectly in
terpretable.
(23)d

In con
trast, the algebra of exten
ts makes a stru
ctural distin
ction betw
een positive an
d
negative exten
ts: positive and n
egative extents are differen
t sorts of objects, wh
ich
represent com
plemen
tary perspectives on th
e projection of an
object on a scale. T
his
distinction
was u
sed to characterize adjectival polarity as a sortal distin
ction: positive
adjectives denote fu
nction
s from objects to positive exten
ts; negative adjectives den
ote
208
208
fun
ctions from
objects to negative exten
ts. Th
e crucial con
sequen
ce of these assu
mption
s
is that th
e range of a positive adjective is disjoin
t from th
e range of its n
egative coun
terpart.
If the sets of positive an
d negative exten
ts are disjoint, th
en an
y expression th
at is a
substitu
tion in
stance of (55) or (56
), wh
ere deg

Th
e end resu
lt is that w

the algebra of exten
ts, cross-polar anom
aly can be explain
ed in
the sam
e terms as in

ensu
rability: the degree relation

ced by the argu
men
ts of mo

embers of th
e same ordered set, th
erefore
210210
the com
parative relation is u
ndefin
ed. Cross-polar an
omaly is th
us a m
ore general
phen
omen
on th
an th
e original facts su
ggest: it does not requ
ire that th
e two adjectives in
the com
parative are mem
bers of a specific positive-negative pair, on
ly that th
ey are of
different polarity. In
deed, the an
alysis proposed here predicts th
at this sh
ould be th
e case.
To su
mm
arize, the explan
ation of cross-polar an
omaly ou
tlined h
ere is available
because th
e algebra of extents perm
its a sortal distinction
between
positive and n
egative
extents to be m
ade at a very basic, structu
ral level. More im
portantly, th
e fact that th
is
anom
aly is observed in th
e first place provides support for th
e hypoth
esis that “degrees”
shou
ld be characterized as in
tervals on a scale, rath
er than
as points on
a scale. If adjectival
polarity is represented as a sortal distin
ction betw
een positive an
d negative adjectives, an
d if
positive and n
egative extents are distin
ct objects, then
we predict th
at comparatives
constru
cted out of polar opposites sh
ould be an
omalou
s. Th
at is, any form
ula w
hich
is a
substitu
tion in
stance of (55) an
d (56) sh
ould fail to retu
rn a tru
th valu
e, because th
e relation
introdu
ced by deg
will be u
ndefin
ed. Ultim
ately, the cru
cial compon
ent of th
e analysis is
the distin
ction betw
een positive an
d negative exten
ts provided by the exten
t algebra, as
similar resu
lts can be derived u
sing altern
ative approaches to th
e seman
tics of comparatives.
For exam
ple, in K
enn
edy 199
7b I assum
e a relational sem
antics for gradable adjectives an
d a
quan
tificational an
alysis of comparatives, an
d I present an
accoun
t of cross-polar which is very
similar to th
e one proposed h
ere. Th
e end resu
lt, then
, is that th
e phen
omen
on of cross-
polar anom
aly provides a compellin
g empirical argu
men
t for formalizin
g “degrees” as
intervals on
a scale–i.e., as extents–rath
er than
as points on
a scale, and for adoptin
g the
sortal characterization
of adjectival polarity described in th
is section (an
d advocated in Seu
ren
1978, 19
84, von S
techow
1984b, an
d Löbner 19
90
).
3.1.8 The D
istribution of M
easure Phrases
As observed by von
Stech
ow (19
84b), the algebra of exten
ts also provides an explan
ation for
211211
the con
trast between
examples like (6
6) an
d (67).
(66
)M
y Cadillac is 8 feet lon
g.
(67)
#My F
iat is 5 feet short.
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
al elemen
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
), is not defin
ed.
(69
)abs(short(m
y Fiat))(5 feet)
212212
Becau
se the orderin
g relation in
(69
) is un
defined, (6
7) is correctly predicted to be
anom
alous.
If this an
alysis is correct, then
it suggests an
explanation
for the fact th
at wh
ile (67) is
anom
alous, (70
) is not.
(70)
My fiat is sh
orter than
8 feet.
Stru
cturally, (70
) is a phrasal com
parative. Given
the an
alysis of phrasal com
paratives
presented in
chapter 2, th
e logical representation
of (70) sh
ould be (71).
(71)m
ore(short(m
y Fiat))(short(5 feet))
Th
e crucial differen
ce between
(71) and (6
9) is th
at the stan
dard value in
the latter is
provided directly by the m
easure ph
rase, wh
ile the stan
dard value in
the form
er is derived by
applying th
e adjective short to the m
easure ph
rase. If it can be sh
own
that th
e result of th
is
operation is th
e negative exten
t that ran
ges from th
e point on
the scale correspon
ding to 5
feet to the u
pper end of th
e scale, then
we w
ill have an
explanation
for this con
trast. I will
leave this as a poin
t for futu
re investigation
.
3.1.9 P
ositives that Look Like Negatives
Ch
ris Barker (person
al comm
un
ication) observes th
at senten
ces like (72)-(74) appear to be
coun
terexamples to th
e claim th
at comparatives form
ed out of positive an
d negative pairs of
adjectives are anom
alous.

.
213213
(74)
She w
as earlier than
I was late.
If the adjectives in
(72)-(74) are actual positive-n
egative pairs, then
the an
alysis outlin
ed in
the previou
s sections in
correctly predicts that th
ese senten
ces shou
ld be anom
alous. T
here
are at least three reason
s to believe that th
e adjectives in (72)-(74) are n
ot positive-negative
pairs, how
ever, but rath
er pairs of positive adjectives. If this is tru
e, then
they are
comparable n
ot to examples of cross-polar an
omaly, bu
t rather to typical exam
ples of
comparative su
bdeletion (su
ch as (19
) and (20
) above), and so are n
ot coun
terexamples to
the claim
s made in
this section
.
T
he first argu
men
t involves in
terpretation. (72)-(74) are n
onan
omalou
s only if th
e
adjectives are interpreted in
such
a way as to m
easure th
e divergence from
some com
mon
point of referen
ce–a “pure ton
e” in (72), th
e “actual tim
e” in (73), an
d “on tim
e” in (74).
Th
is is particularly clear in
the case of (73), w
hich
can on
ly mean
that th
e extent to w
hich
my
watch
is faster than
the actu
al time is greater th
an th
e extent to w
hich
your w
atch is slow
er
than
the actu
al time. (73) can
not be u
sed to make th
e claim th
at my w
atch is m
ore
temporally advan
ced than
yours, w
hich
wou
ld be true in
a situation
in w
hich
both of ou
r
watch
es were slow
. An
interpretation
of (73) along th
ese lines is an
omalou
s in th
e same w
ay
that (75) is:
(75)#M
y car is faster than
your car is slow
.
Th
e second argu
men
t comes from
the distribu
tion of overt m
easure ph
rases. A
characteristic of n
egative adjectives is that th
ey cann
ot be modified by overt m
easure ph
rases
(see section 3.1.8):
(76)
#Mr. R
eich is 5 feet sh
ort.
(77)#M
aureen
was drivin
g 14 mph
slow.
214214
Both
of the adjectives in
each of (72)-(74) perm
it measu
re phrases, h
owever, w
hen
they are
interpreted in
the w
ay described above, so that th
ey measu
re divergence from
a reference
point. (78)-(80
) illustrate th
is point.
(78)
You
r C is 30 H
z flat/sharp.
(79)
My w
atch is 10 m
inutes fast/slow.
(80
)Sh
e was an hour early/late.
Th
e third argu
men
t makes u
se of the observation
that statem
ents w
hose logical
forms are su
bstitution
instan
ces of (51), repeated below, are valid for an
y positive-negative
pair of adjectives.
(51)ϕ
pos (a) > ϕpos (b) iff ϕ
neg (b) > ϕn
eg (a)
If flat-sharp, fast-slow, an
d early-late, are actual positive-n
egative pairs, then
(81)-(83) shou
ld be
valid.
(81)
You
r A is sh
arper than
your D
iff your D
is flatter than
your A
.
(82)
My w
atch is faster th
an you
rs iff yours is slow
er than
min
e.
(83)
She w
as earlier than
I was iff I w
as later than
she w
as.
Th
ese statemen
ts are not valid, h
owever, on
the relevan
t interpretation
. Alth
ough
(83), for
example, is valid if late an
d early describe the relative tem
poral ordering of tw
o individu
als
(with
respect to some even
t), it is not valid if th
e adjectives describe deviation from
some
reference poin
t indicatin
g “on tim
e”. On
the latter in
terpretation, th
e first conju
nct w
ould
be true in
a context in
wh
ich w
e were both
early, but sh
e was earlier th
an I w
as, wh
ile the
215215
second con
jun
ct wou
ld be false, because n
either of u
s was late. T
his latter in
terpretation is
the on
e the adjectives m
ust h
ave in (74), h
owever: if th
ey are interpreted so th
at (83) valid,
(74) is anom
alous.
Th
e data discussed h
ere support th
e conclu
sion th
at both m
embers of th
e adjective
pairs in (72)-(74) are positive: adjectives like sharp an
d flat (as well as fast-slow
and early-late,
on th
e relevant in
terpretations), w
hich
measu

Th
e extent approach
to the sem
antics of gradable adjectives con
sists of two prin
cipal claims.
First, gradable adjectives den
ote relations betw
een in
dividuals an
d extents. A
n exten
t is
defined as an
interval on
a scale, and a stru
ctural distin
ction is m
ade between
two sorts of
extents: positive exten
ts and n
egative extents. S
econd, positive an
d negative adjectives are
distingu
ished by th
e sort of their exten
t argum
ents: positive adjectives den
ote relations
between
individu
als and positive exten
ts; negative adjectives den
ote relations betw
een
individu
als and n
egative extents.

cann

his in

contrasted w
ith th

wh

Th
at these sen

For exam

On
the su
rface, comparison
of deviation con
struction
s appear to be problematic for
the an
alysis of cross-polar anom
aly developed in section
3.1, wh
ich predicted th
at any
comparative con
structed ou
t of a positive and n
egative pair of adjectives shou
ld trigger
incom
men
surability. O
n closer in
spection, h
owever, com
parison of deviation
constru
ctions
like (84)-(87) actually provide in
teresting su
pport for the an
alysis of cross-polar anom
aly.
Con
sider, for example, th
e interpretation
of (84). Wh
at is crucial to observe is th
at this
senten
ce does not sim
ply permit th
e type of interpretation
discussed above, in
the com
pared
objects are the exten
ts to wh
ich th
e compared in
dividuals exceed appropriate stan
dards of
tallness an
d shortn
ess, (84) has only th
is type of interpretation
. In particu
lar, (84) cannot
mean
that th
e compared in
dividuals are (at least) equ
al in h
eight. T
his latter readin
g, wh
ich
wou
ld correspond to th
e standard in
terpretation of th
e equative con
struction
, is correctly
ruled ou
t by the an
alysis of cross-polar anom
aly developed above.
To see w
hy, con
sider the logical represen
tation of (84) on
this in
terpretation:
219219
(94
)as(tall(W
illiam))(m
ax(λe[abs(short(R

Assu
min
g the tru
th con
ditions for th
e equative given
in section
3.1.6, th
e interpretation
of
(84) represented by (9
4) is ruled ou
t as an in
stance of cross-polar an
omaly: th
e argum
ents
of as are not elem
ents of th
e same ordered set, so th
e partial ordering relation
introdu
ced
by the degree m
orphem
e is un
defined. A
similar case can
be made for (85). T
he pu
zzle
that rem
ains to be solved is h
ow th
e comparison
of deviation in
terpretation arises in
the first
place. I will address th
is question
in th
e next section
.
3.2.2 Differen
tial Exten
ts and C
omparison
of Deviation
As n
oted above, the basic in
terpretation of com
parison of deviation
constru
ctions do n
ot
involve com
parison betw
een “absolu
te” extents (w
here an
absolute exten
t is the projection
of some object on
to a scale), but rath
er comparison
between
the exten
ts to wh
ich tw
o
objects each exceed an
appropriate standard. C
onsider, for exam
ple, (84), repeated below, in
a context in
wh
ich th
e positive projection of W
illiam on
a scale of heigh
t is tall(w) an
d the
negative projection
of Robert on
a scale of heigh
t is short(r), as show
n in
(95).
(84
)W
illiam is as tall as R
obert is short.

If the stan

tall(w) = e

If absolute exten

hat is, e1 an
d e2
represent th
e extents to w
hich
Bradley an
d Reich
exceed standards of talln
ess and
shortn
ess, respectively.
I wou
ld like to suggest th
at comparison
of deviation in
volves comparison
of such
“differential exten
ts”. Specifically, th
e comparison
of deviation in
terpretation of (8
4)
involves a relation
between
e1 and e2 in
(95). B
uildin
g on th
e standard in
terpretation of th
e
equative, th
e comparison
of deviation in
terpretation of (84) can
be characterized as in
(97):
(97)
||(84)|| = 1 iff e1 ≥e2 , w
here e1 •stall = tall(w
) and e2 •sshort = short(r).
Note th
at in order to evalu
ate the orderin
g relation in
(97), it m
ust be th
e case that th
ere is
a mappin
g between
e1 and e
2 and tw
o extents th
at share an
endpoin
t, e.g. e’1 and e’2 ,
respectively, in(9
8).
14Som
e kind of con
catenation
operation on
extents is in
dependen
tly required to in
terpret
“differential” com
paratives like (i) and (ii) (see von
Stechow
1984a, H
ellan 19
81).
(i)W
illiam is 2 feet taller th
an R
obert.
(ii)San
Fran
cisco Bay is over 150
fathom
s shallow
er than
Mon
terey Bay.
Intu
itively, a senten
ce like (i) asserts that th
e extent to w
hich
William
is tall exceeds the exten
t to
wh
ich R
obert is tall by the am
oun
t denoted by 2 feet.

Th
is could be accom
plished in
the follow
ing w
ay. In addition
to the set of positive an
d
negative exten
ts on a scale S
δ , we can
define a set of bou
nded exten
ts: the set of bou
nded
proper intervals on
the scale. 15 A
ssum
ing th
at an explicit th
eory of measu
remen
t can be
overlaid onto th
e theory of scales (see K
lein 19
91 for som
e promisin
g initial proposals in
this
direction), w
e can m
ake the n
atural assu
mp
tion th
at all boun
ded extents of equ
al
measu
remen
t are equivalen
t (i.e., we can
group bou
nded exten
ts into equ
ivalence classes
based on th
eir measu
remen
ts). If this is th
e case, then
e1 and e2 in
(95) are equ
ivalent to e’1
and e’2 in
(98) respectively, an
d it follows th
at if e’1 ≥e’2 , th
en e1 ≥
e2 .
15Th
is assum
ption en
tails that for an
y scale with
a min
imal elem
ent, th
e set of positive
extents is a su
bset of the set of bou
nded exten
ts. If the h
ypothesis th
at measu
re phrases den
ote
boun
ded extents is correct (see section
3.1.8), w
e make th
e followin
g prediction: on
ly positive
adjectives that m
ap their argu
men
ts onto scales w
ith a m
inim
al elemen
t will perm
it measu
re
phrases, sin
ce only in
these cases w
ill the correspon
ding positive exten
ts be boun
ded. Th
is
prediction appears to be born
e out by w
ell-know
n con
trasts like (i) and (ii), assu
min
g that th
e scale
associated with w
arm (a scale alon
g a dimen
sion of “tem
perature”) h
as no low
er boun
d.
(i)#It’s 50
degrees warm
today.
(ii)T
he kitch
en is 50
degrees warm
er than
the basem
ent.
Th
e importan
ce of (ii) is its acceptability indicates th
at a standard of m
easurem
ent is defin
ed for the
scale onto w
hich
warm
maps its argu
men
ts, thu
s the u
nacceptability of (i) can
not be du
e to an
absence of su
ch a stan
dard (as could be argu
ed for an adjective like beau
tiful, for exam
ple). Even
thou
gh th
ere may be an
actual low
er boun
d on th
e temperatu
re of objects in th
e un
iverse, it seems
reasonable to assu
me th
at the scale on
to wh
ich th
e adjective warm
maps its argu
men
t does not h
ave
a lower bou
nd, given
the fact th
at a senten
ce such
as Absolute zero is w
armer than nothing is perfectly
interpretable.
222222
In order for th
e general approach
to comparison
of deviation ou
tlined h
ere to go
throu
gh, h
owever, it m
ust be sh
own
that com
parison of differen
tial extents in
examples
involvin
g p
ositive an
d
negative
adjectives
(such
as
(84
)-(87))
does
not
result
in
incom
men
surability. T
hat is, it m
ust be sh
own
that differen
tial extents are sortally th
e
same, regardless of w
heth
er they are su
bintervals of positive exten
ts or subin
tervals of
negative exten
ts, so that th
e comparison
relation is defin
ed in exam
ples like (84)-(87). In
fact, this resu
lt follows from
the defin
ition of exten
t concaten
ation in
(96
). Tw
o initial
condition
s are importan
t. First, sin
ce we are on
ly interested in
cases in w
hich
ed •e is the
argum
ent of a gradable predicate, it m
ust be th
e case that e’ is eith
er positive or negative,
therefore e’ m
ust be a proper exten
t. Secon
d, e and e’ m
ust be exten
ts of the sam
e sort:
both positive or both
negative. T
his follow
s from th
e definition
of an exten
t as a convex
subset of a totally ordered set of poin
ts: if e.g. e and e’ w
ere of opposite polarity, then
the
value of e’ - e, w
hich
equals –(e’ ∩
e), wou
ld not be con
vex, and th
erefore not an
extent.
Assu
min
g these in
itial condition
s, two qu
estions m
ust be an
swered: w
hat is th
e sort
of ed wh
en e is positive, an
d wh
at is the sort of ed w
hen
e is negative? In
the case in
wh
ich e
is positive, ed mu
st be a boun
ded extent (i.e., a proper su
bset of S - e), oth
erwise e’ w
ould n
ot
satisfy the con
dition th
at it be a proper extent. W
hen
e is negative, ed again
mu
st be
boun
ded in order to en
sure th
at e’ is a proper extent. T
he con
clusion
is that a differen
tial
extent is bou
nded w
hen
concaten
ated with
either a positive or a n
egative extent, a fact w
hich
I interpret as in
dicating th
at differential exten

rally) of the sam
e sort. 16 Th
is is
consisten
t with
the h
ypothesis m

16Eviden

the set of bou

tial extents are m
embers of th
e same
set of boun

d assum
ing th
at mappin
gs of the sort defin
ed above can be
determin
ed, it shou
ld be possible to establish an
ordering relation
between
any tw
o
differential exten
ts. Th
erefore the com
parison relation
associated with
comparison
of
deviation con
struction
s shou
ld be defined.
To su
mm
arize the discu
ssion so far, I h
ave suggested th
at comparison
of deviation
involves a relation
between
differential exten
ts, rather th
an a relation
between
absolute
extents, as in
standard com
parative/equative in
terpretations. C
omparison
of deviation is
possible in con
texts in w
hich
standard com
parison triggers in
comm
ensu
rability because
differential exten
ts are sortally the sam
e, regardless of the sort of th
e extent w
ith w
hich
they are con
catenated. A
positive result of th
is analysis is th
at it explains w
hy com
parison of
deviation in
terpretations h
ave the en
tailmen
ts they do. F
ocusin
g on (84), if tall(b) = e1 •stall ,
then
tall(b) ≥ stall . Accordin
g to the sem
antics of th
e absolute adopted in
chapter 2, it follow
s
that th
e statemen
t William
is tall is true. M
ore generally, if th
e differential exten
ts wh
ich
are compared in
comparison
of deviation con
struction
s denote th
e difference betw
een th
e
absolute exten
t of an object an
d an exten
t wh
ich den
otes an appropriate stan
dard, then
the
truth
condition
s for the absolu
te are indepen
dently satisfied. 17
17A fin
al question
remain
s un
answ
ered: wh
at is the differen
ce in com
positional sem
antics
between
standard com
parative constru

d comparison
of deviation con

s? Alth
ough
this is a qu

ave to leave for futu
re work, a con

odifiers such
as
very, fairly and qu

initially prom

. Like comparison
of

s, degree modifiers also in
volve comparison
of extents w

measu
re the

of an object on

onsider, for

Mon
otonicity properties represen
t one of several factors w
hich
have tradition
ally been u
sed
to classify gradable adjectives according to th
eir “logical polarity” (in th
e sense of H
. Klein
199
6): adjectives w
hich
license n
egative polarity items an
d down
ward en
tailmen
ts in clau
sal
complem
ents, su

egative, wh
ile adjectives wh
ich
do not licen
se negative polarity item
s but do perm
it upw
ard inferen
ces, such
as easy and
comm
on, are classified as positive (see Seu
ren 19
78 for early discussion
of this issu
e). Th
e
goal of this section
is to show
that th
e mon
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
eir range: positive adjectives den
ote fun
ctions from
individu
als to
positive extents; n
egative adjectives denote fu
nction
s from in
dividuals to n
egative extents.
3.3.2 Degrees an
d Mon
otonicity
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
ents like (10

Degrees of lon

the differen
ce in
the orderin
g relations associated w
ith positive an
d negative adjectives, th
e two con
jun
cts in
(108) are tru
e in exactly th
e same situ
ations.
Th
is representation
of logical polarity has an
additional positive resu
lt: it entails th
at
negative adjectives are m
onoton
e decreasing. T
o see wh
y, consider an
arbitrary case of
ordering alon
g a dimen
sion, for exam
ple, safety. If b is safer than
a, then
the relation
in
(109
) holds.
(109
)a <
safety b
If the orderin
g relation associated w

al of the relation
associated with
its positive coun
terpart, then
given th
e analysis of gradable adjectives as
fun

Given

f is monotone increasing iff: a < b →
f(a) < f(b)

Alth
ough
this is a positive resu
lt, it mu
st be acknow
ledged that th
e mon
otonicity of
negative adjectives does n
ot follow from
an in
dependen
t aspect of the algebra of degrees.
Rath
er, it is a definition

at negative adjectives are scale

med in
order to constru
ct a seman

ich correctly accou
nts for th
e
interpretation
s of positive and n
egative adjectives in th
e absolute an
d comparative form
s.
Noth
ing abou
t the system
itself requires n
egatives to be mon
otone decreasin
g; rather, it is
the data w
hich
force this assu
mption
. An
alternative situ

ould be on

indepen
dently m
otivated characteristics of th
e ontology h
ave the addition
al consequ
ence th
at
negative adjectives are scale reversin

e discussion
of cross-polar anom
aly in section
3.1
demon
strated that th
e distinction
between
positive and n
egative extents provided by an
extent algebra is in
dependen
tly motivated, as it su
pports an explan
ation of cross-polar
anom
aly (someth
ing th
e algebra of degrees fails to do). In th
e followin
g section, I w
ill show
that th
is distinction
has th
e additional positive resu
lt of deriving th
e mon
otonicity properties
of gradable adjectives.
3.3.3 Exten
ts and M
onoton
icity
Th
e conclu
sion of section
3.1 was th
at scalar values (“degrees”) sh
ould be form
alized in
terms of in
tervals of a scale, as originally proposed by S
euren
(1978) (see also von
Stech
ow
1984b an
d Löbner 19
90
), and polar opposition
shou
ld be represented as a sortal distin
ction
229229
between
positive and n
egative adjectives: positive adjectives denote fu
nction
s wh
ose range is
the set of positive exten
ts Epos ; n
egative adjectives denote fu
nction
s wh
ose range is th
e set of
negative exten
ts En
eg . In addition
to supportin
g a principled explan
ation of cross-polar
anom
aly, this sortal ch
aracterization of adjectival polarity h
as the positive con
sequen
ce of
entailin
g that positive adjectives are m
onoton
e increasin
g fun
ctions an
d negative adjectives
are mon
otone decreasin
g fun
ctions.
Con
sider again th
e case of an orderin
g along a dim
ension
of safety, in w
hich
an object
a is ordered below an
object b, as in (113)
(113)a <
safety b
Wh
en th
e relation betw
een a an
d b show
n in
(113) holds, th
en th
e values of safe(a) an
d
safe(b), and dangerous(a) an
d dangerous(b) (i.e., the positive an
d negative exten
ts of a and b on
the scale of safety) are as sh
own
in (114).

230230
Th
e positive adjective safe preserves the orderin
g on a an
d b, but th
e negative adjective
dangerou
s reverses it. Th
erefore safe is mon
otone in
creasing, an
d dangerou
s is mon
otone
decreasing. T
his resu
lt does not follow
from som
e property of safe and dangerous; rath
er it is
a general con
sequen
ce of the h
ypothesis th
at logical polarity is represented as a sortal
distinction
between
gradable adjectives. Wh
at distingu
ishes th
is result from
the on
e
obtained in
the degree approach
is that it follow
s directly from th
e algebra of extents, n
ot
from prior assu
mption
s about im
plicit ordering relation
s associated with
the adjectives safe
and dangerous. 19
3.3.4 Summ
ary
Takin
g differences in
mon
otonicity properties of gradable adjectives as a startin
g point, th
is
section con
sidered two altern
ative representation
s of logical polarity. Th
e degree analysis
makes th
e assum
ption th
at negative adjectives are scale reversin
g at a basic level; rather th
an
explainin
g wh
y negative adjectives are m
onoton
e decreasing, it defin
es them
as such
. Th
e
extent approach
, on th
e other h
and, derives th
e mon
otonicity properties of polar adjectives
from th
e sortal distinction
between
positive and n
egative adjectives provided by the algebra
of extents. T
his approach
is indepen
dently m
otivated because, u
nlike th
e degree algebra, it
supports an
explanation
of cross-polar anom
aly.
It is worth
notin
g that th
e proposals I have m
ade here do n
ot predict wh
ether an
adjective is going to be positive or n
egative–nor are th
ey inten
ded to. Th
e goal is rather to
present a form
al representation
of adjectival polarity wh
ich accou
nts for th
e logical
properties of gradable adjectives in as robu
st and explan
atorily adequate a w
ay as possible.
19If the n
omin
al determin
ers many an
d few are an
alyzed as positive and n
egative gradable
predicates, respectively (Klein
1980
, see also Sapir 19
44), then
it shou
ld be possible to explain th
eir
mon
otonicity properties in
the sam
e way.
231231
Th
e facts I have con
sidered in th
is paper show
that a form
al system in
wh
ich polarity is
represented as a sortal distin
ction betw
een gradable adjectives ach
ieves this goal.
3.4 Con
clusion
Th
e pu
zzle wh
ich form
ed the startin
g poin
t for this ch
apter w
as the an
omaly of
comparatives form
ed of positive and n
egative pairs of adjectives. Observin
g that th
is
anom
aly is un
explained if degrees are an
alyzed as points on
a scale, I claimed th
at degrees
shou
ld instead be form
alized as intervals on
a scale, or extents, an
d I made a stru
ctural
distinction
between
two sorts of exten
ts: positive extents, w
hich
range from
the low
er end
of the scale to som
e positive point, an
d negative exten
ts, wh
ich ran
ge from som
e point to
the u
pper end of th
e scale. Adjectival polarity w
as then
characterized as a sortal distin
ction
between
positive and n
egative adjectives: positive adjectives denote fu
nction
s from objects to
positive extents; n
egative adjectives denote fu
nction
s from objects to n
egative extents. T
his
approach n
ot only su
pported a principled an
alysis of cross-polar anom
aly, it also explained th
e
different relation
al characteristics of positive an
d negative adjectives, an
d provided the basis
for an explan
ation of th
e interpretation
of comparison
of deviation con
struction
s. Fin
ally,
the algebra of exten
ts and th
e sortal characterization
of adjectival polarity has th
e additional
positive result of en
tailing th
at positive adjectives denote m
onoton
e increasin
g fun
ctions an
d
negative adjectives den
ote mon
otone decreasin
g fun
