246 The
Philosophy
of
Leibniz
entities.
To
account
for
this,
he has to
find
a way of
reformulating such state-
ments
as
statements that more clearly concern individuals only.
To use
Leib-
niz's favorite example: statements apparently concerning
the
abstract entity
Heat
are to be
recast
as
statements involving, instead,
the
predicate
"is
hot,"
as
applied
to
individual things.
Now,
Leibniz's philosophy itself
is
full
of
talk about abstract
entities,
some
of
which
are
even original with him.
There
is the
complete individual
concept
of
Alexander, which involves everything that
has
ever happened,
is
happening,
or
will
happen
to
him,
and
which even bears
within
it
signs
of
everything that
has
ever happened,
is
happening,
or
will
happen
in the
entire
universe.
So, as a
nominalist, Leibniz
has a lot of
explaining
to do.
This
is
where
God
comes
in.
Leibniz emphasizes time
and
again that
all of
these indi-
vidual
concepts,
and the
rest
of the
"realm
of
ideas"
are
"ideas
in the
mind
of
God";
and he
explains further than
an
idea, unlike
a
thought (which
is an
actual
occurrence
at a
given time),
is a
disposition
to
have certain thoughts
if
certain conditions
are
met.
In
other
words,
to
have
an
idea
is to be
disposed
to
think
in a
certain way.
Hence,
the
"reality" upon which statements like that about Alexander's
concept
are
grounded
is not a
shadowy collection
of
abstract entities "sub-
sisting" somewhere between Being
and
Nothing,
but a
particular though very
special
individual, God,
with
all his
qualities, capacities,
and
dispositions.
I
think
it
clear enough that this
is
Leibniz's underlying view
or
attitude, even
if
he
never states
it as
explicitly
as I am
doing now.
He
gives
us
very
few
indi-
cations
of how
specific cases
are to be
analyzed,
but
there
can be
little doubt,
it
seems
to me,
that
in
ascribing
the
aforementioned attributes
to the
com-
plete individual concept
of
Alexander,
he
understands himself
to be
really
talking
about
the
state
of
God's
mind when Alexander
was
created.
Those
of us who
have what might
be
called
an
"extensional"
view
of the
world
are
inclined
to
postulate, behind every dispositional property, some
nondispositional properties that
are the
ground
of its
application.
The
para-
digmatic
lump
of
sugar that
is now
soluble
in
water, even
if it
will
never
be
dis-
solved, possesses this dispositional property
by
virtue
of the
nondispositional
property
of
having
a
certain crystalline structure. Presumably
God's
capacity
to
create this
or
that kind
of
world
is
similarly based upon
his
knowledge,
motives,
and
skills.
And the
same assumption would lead
to the
conclusion,
I
suppose, that
a
disposition
of God or of
anyone else
to
think
in
certain ways
must
be
grounded
in the
nondispositional qualities
of his
mind.
It is not
difficult
to see how the
same reductive strategy would apply
to
other statements about individual concepts
and to
statements about other
abstract entities.
In
sum, Leibniz's belief
in
this very special individual, God,
permits
him to
remain
a
nominalist while using
the
whole philosophical
apparatus
of
concepts, propositions, ideas, possible worlds.
Doubts
about
the
cognitive content
of
metaphysics
in
general,
or of
Leib-
niz's metaphysics
in
particular,
need
not
prevent
us
from
indulging
in
some
