If you have always wondered how to find
out what other people have in mind, Wolff instructs how to do it. One
might wonder what this has to do with the topic of Wolff's German
ethics. Well, in order to do good things, you must learn what is good
and what is not – and one way to do this is to see what others
think is good.
Wolff's method is rather simple.
Suppose a person perceives or otherwise experiences some situation
and in her imagination and memory she has a maxim telling whether
such a situation is good or bad and what one should do in that sort
of situation. Then through a simple syllogism we see that the person
will evaluate the situation and act in a certain manner. So, if a
person sees a beggar and her maxim is to donate to the poor, she will
give an alm.
Then again, we can also reverse the
process. In other words, if we know the particular experiences a
person has and the actions following from these experiences, we can
instantly know what general maxims she follows in her actions. Thus,
if we see a person giving a fiver to a beggar he has just seen, we
can suppose that the person has a general maxim of helping the poor.
Of course, it is not as simple as that,
because people can act contrary to their maxims, if they feel the
need to deceive other people. For instance, the person giving the
alms in the last paragraph might only want to make an impression to a
lady who truly likes charity. Generally, the possibility of deception
prevents us to be truly certain of what is going on in other people's
minds.
Wolff suggests a method for
circumventing the possibility of deception. Although one's actions
can be deceiving, emotions cannot be – that is, if a person thinks
some situation to be good or bad, we can assume that she will
generally evaluate similar situations in the same manner. Hence, the
person trying to fool a lady with a generous gift to the beggar would
be instantly revealed by his emotion that he disliked his act of
charity.
Maxims could thus be read from
emotions, but how can emotions of a person be deciphered? Now, as we
might remember from Wolffian psychology, Wolff's and Leibniz's dualism with a pre-estabished harmony verges
on materialism. Indeed, because of the harmony, one can at least in
principle find out what emotion a soul is feeling, when one is
studying the corresponding body. Indeed, we do evaluate the emotions
of people by looking at the expressions of their faces and other
non-verbal forms of communication. But Wolff goes a step further and
appears to accept the validity of physiognomy.
Physiognomy is a discipline of great
antiquity: there is a book called Physiognomy, which was ascribed to
Aristotle, although the author was probably just a member of the
Aristotelian school. The basic idea behind this discipline is rather
simple – by studying the physical characteristics of a person we
could determine also his mental characteristics. Classic physiognomy
appealed, for instance, to resemblance with other animals – if he
looks like a pig, he is probably going to behave like a pig.
Physiognomy was criticised even during Wolff's life and is nowadays dead as a dodo when it comes to respectable
science, but similar statements can be found in more modern
disciplines. For instance, genetic determinists are certain that the
personality of a person is completely encoded in her DNA. Thus,
Wolff's readiness to accept physiognomy implies that he might not be
completely against these later theories – genetics would not then
be in contradiction with Wolffian dualism.
Yet, Wolff did not accept even
physiognomy wholly, because of a point familiar from the
genes-environment -discussion: while physiognomy might be correct of
human beings in their natural state, education can change the
temperament of a person. Ironically, Wolff has more difficulties in
combining the possibility of educating a person with his view of the
human soul: because human soul is actually closed up from external
influences, it cannot really be educated, that is, other people only
seem to educate the person, who then develops freely from his natural
state.
Nevertheless, Wolff admits that
physiognomy is not a reliable method for deciphering people's
emotions, and thus the hopes of reading other people's minds have
been destroyed. This appears to be a common theme in Wolff's
philosophy: he sets out an ideal of knowledge and even develops a
method for acheiving it – but in the end, human frailties hinder
the use of the method.
Next time, we shall look at the duties
of a moral person.
