The
intellective
soul
499
Platonic
notion of innate ideas as the intermediate between the universal
divine and the individual human agent intellect. In Themistius, the first and
third
agent intellects
are
said to be unified,
while
the second is multiplied,
107
but all three are considered to be unified in the act of cognition.
108
Using
this concept
Nifo
succeeded in reconciling
Averroes'
theory with the claim
for
individuality
of
the
human intellectual soul found in the Latin tradition
and
in making both compatible with Alexander's agent intellect as God.
As is obvious from such a solution,
Nifo's
reasoning was
less
concerned
with the natural philosopher's saving the phenomena than with the
constitution of
a
set of metaphysical principles unspecific enough to allow
for
an integration of as many concepts of the phenomena as possible.
Indeed, when a concept resisted such an integration, as with Averroes'
denial of an individual intellect or with
Jandun's
assumption of an agent
sense, the decisive argument for
Nifo
does not seem to have been an
insufficient explanation
of
the
phenomena, but the supposition
of
a
starting-
point based on the wrong general principles.
109
The
same attitude towards philosophical argument allowed
Nifo
to
maintain
that the immortality of the individual human soul was
true
not
only in terms of Christian revelation, but also on the grounds of
philosophical demonstration.
110
Of
course,
Nifo
did not conceal that some
of
the most celebrated Latin commentators, for instance, Duns Scotus,
111
had
regarded the question to be a
problema
neutrum because of Aristotle's
contradictory
statements and therefore insoluble in terms of natural
philosophy.
112
Yet, in
order
to prove the immortality of the individual
soul, he does not rely on
a
refutation
of
this position
argument
by argument,
but
rather
on a collection of statements in favour of immortality drawn
from
Neoplatonic sources, such as Plato and Plotinus, as
well
as from
Hermes
Trismegistus, the son
of
Prometheus
(who is called the first of the
Stoics),
Cicero,
Sallust, Xenophon, Ptolemy and a near infinity of ancient
philosophers and different schools.
113
Only then does
Nifo
add those
statements
of
Aristotle
which seem to fit into this general consensus.
114
It is
pars
animae
rationalis
. . . Tertius est
intellectus
agens,
ut
instrumentum
immediatum
omnium
intellectorum
speculativorum;
et hie
sunt
propositiones
primae,
nobis
per
naturam
insitae.'
