Psychology
The
De
anima
was by far the most important of these treatises. Virtually
all universities required it to be read for the degree of bachelor of
arts,
an
honour it shared only with the
Physics
among Aristotle's non-logical
works.
5
The
Paw
a
naturalia
and animal books gained new importance
during the Renaissance, as the object of medical and philosophical study in
their
own right and as
part
of
the humanist effort to recover and disseminate
the entire Aristotelian corpus; by the middle
of
the sixteenth century some
writers
even argued that they should precede De
anima
in the order of
investigation and teaching.
6
Nonetheless, De
anima
—
above all the second
and third books — continued to determine the content and order of
psychological enquiry. In the sixteenth
as
in the thirteenth century, students
and teachers began by considering the nature and types of soul before
moving on to the more specific topics
of
reproduction,
digestion, sensation
(including basic optics and acoustics, as
well
as the higher sensitive functions
of
memory and imagination), intellection, appetite and
will.
If
physics was the foundation of Aristotelian natural philosophy,
psychology was its culmination, as Aristotle and after him Averroes had
noted, since, unlike the other branches
of
natural
philosophy, it treated the
principles governing animate
rather
than inanimate bodies.
7
Because it
considered the nature and functions of the specifically human soul and
body, among others, psychology overlapped many other areas
of
enquiry.
Philosophers considered psychology relevant to ethics, which required a
basic understanding of the soul as the source
of
man's thoughts and actions
and the seat
of
his ultimate perfection.
8
Because man's intellective soul was
regarded
as the lowest substance
wholly
separable from
matter,
psychology
also confronted the problem
of
immaterial
substances, the subject
of
divine
philosophy or metaphysics. Thus Paul
of
Venice
followed
the treatise on the
soul in his Summa
philosophiae
naturalis
by a treatise on metaphysics,
9
and
5. The Parva naturalia
were
often
required
only
for the
most
advanced
licence
in arts,
while
the
books
on
animals
and
plants
usually
served
only
as
supplementary
texts,
as the
relatively
small
number
of
commentaries
devoted
to
them
shows.
