After proving that soul or
consciousness exists and that we can in some measure study it, Wolff
begins to discuss the theoretical or cognitive part of soul. I might
notice, by the way, that this is a rather common ordering, and
indeed, I have never seen a philosophical study of consciousness
begin with volition. The custom goes all the way back to Aristotle's
De Anima, and presumably
every philosopher has just copied his predecessors in this matter.
Before actually beginning
to study any cognitive faculties, Wolff defines certain notions
common to all of them, starting from the concept of faculty itself.
Scholars of German philosophy are often so ingrained in the language
of faculties that they fail to ask even what is meant by a faculty.
Wolff actually defined the term already in his ontology, where it was
explicated as any active potentiality, that is, any possibility to do
something that was actually engaged with actualising this
possibility. In other words, faculties of soul or mind are just
capacities of mind to do something, but also not passive. Instead,
they are active or actually use what they can do.
After faculty, Wolff
continues by describing what is meant by clarity and distinctness of
perceptions or representations. The notions themselves I have
explicated quite sufficiently for a number of times: clarity means
for Wolff ability to distinguish a perception, while distinctness
means ability to recognise partial perceptions that help to
distinguish the whole perception. I could still note one more time
that these concepts should not be read as forming a strict division
to e.g. clear and unclear perceptions. Instead, they work more as
defining a scale of clarity and distinctness: we can distinguish an
object with various accuracy in different situations, and analysis
required for distinctness might reveal further characteristic marks.
This notion is further backed up by the fact that Wolff calls clarity
of perception light of soul – light does not form a clear division
with darkness, but between light and total darkness there are many
shadows and gray areas.
These very same
perceptions can also be called ideas, although Wolff prefers defining
idea as a representation, in which we are especially interested of
the object represented: that is, when we talk of perceptions, we talk
of an act of subject, but when we talk of ideas, we talk of
individual objects. Concepts, on the other hand, are representations
of general characteristics of things, of genera and species.
Cognition, then, means acquiring ideas and concepts of various
things, that is, conceiving what things and their characteristics
are. Cognition can then have various levels of clarity, but Wolff
places the most important distinction on whether the ideas and
concepts involved are distinct, that is, analysed into further ideas
and concepts. Cognition with distinct ideas and concepts is in
Wolffian psychology on a level higher than cognition with obscure and
confused ideas and concepts, that is, one should aim at analysing
one's ideas and concepts.
Wolff begins the
study of cognition from faculties of lower level. Wolff's choice
reflects a natural development – we begin with confused and even
obscure ideas, which little by little become clearer and more
distinct. Thus, it is no wonder that Wolff begins with sensations,
which presumably are the beginning of all cognition. Sensations are
also the link of human cognition to the external physical world. An
important element of this world is our own
body that appears constantly attached to us and seems to be in
continuous correspondence with certain perceptions (note how Wolff
avoids the question whether this correspondence is explained by
actual interaction between body and human mind or whether there is no
interaction between them – such questions will be tackled in
rational psychology).
Sensation, then, is defined by the special correspondence between
human mind and sensory organs of the body, that
is, sensation is a perception that can be understood by basis of
changes in these organs (even if they are not caused by these
changes).
Because
sensation is studied by Wolff in a part dedicated to the lower part
of human cognition, it becomes natural to ask if Wolff completely
discarded sensation as without any value and completely obscure. Yet,
the idea of clarity and distinctness as a scale instead of division
makes it possible that sensation could rise in clarity and even gain
some distinctness. This is especially shown to be true by Wolff's
investigation of attention and reflection, but even sensations
themselves contain levels of clarity – a stronger sensation is also
clearer than a weaker sensation. A further
value of sensations lies in their relative freedom from arbitrary
whims of human mind. Thus, if one is looking at some spot, one cannot
just choose what one is seeing. The only way to control what one
senses is to move to another spot or at least look to somewhere else.
So much for
sensations, next time I shall turn to imagination.
