According to Aristotle, the progress
from sense perception through memory and experience to true knowledge
involves growing generalisation: while in perception we see only
singular appearances, in experience we become acquainted with a
number of objects of the same sort and in knowledge we can finally
recognise that objects of certain sort necessarily have certain
characteristics. The generalisation means loss of some concreteness –
”animal in general” is not coloured or at least does not have any
peculiar colour. Still, it also allows us to deal with a set of
various objects in a conveniently short manner.
Aristotle envisioned that the
generalisation progress would have a limiting point, which he
described as the first philosophy – not first in the order of
learning, but first in the sense of importance. This first philosophy
would be farthest from concrete experiences, but still deserves the
name wisdom as the final aim of human endeavours. Note how Aristotle
here moves away from the original meaning of wisdom as the capacity
to know how humans should live – Aristotelian wisdom is far above
such pragmatic concerns.
In this primary field of inquiry one
should e.g. determine what facets of an object are required for its
proper description. Aristotle noted that most of the earliest
philosophers had exhaustively described how every-day objects are
made out of materials like water and air. Only some had had the idea
of describing basic forces that were supposed to activate the
combination and recombination of materials. Platonists had had some
inkling that describing the structures of the things would help in
explaining them, although they had apparently thought of these
structures as things independent of the every-day things, thus
needlessly multiplying the number of entities. Finally, many of the
previous thinkers and poets had emphasised how the world was good or
in accord with some purposes. These four facets – materials out of
which things are made of, forces changing the things, structures
characterising the things and the purpose for the sake of which
things exist – are then the only things required for a complete
description of a thing and its processes.
Aristotle also noted that description
of all the four facets must end at some point. If a statue is made of
bronze, bronze is made of further elements and so on, this
progression of constitution must end at some ultimate material, which
is not made of anything. Similarly, everything embodies various
structures – it is e.g. brazen, statue, likeness of a Greek
philosopher etc. – but some structure of the thing is full in the
sense that the thing cannot be modified or structured any further.
Furthermore, changes of a thing must begin from some first change,
and the changes must have some ultimate goal, which has not been
striven for because of a further goal.
There would then have to be four
different sorts of ultimate principles, from which all explanations
and descriptions should begin. The problem is whether all of the four
principles should be investigated by the same field of philosophy or
whether they all should have their own disciplines. The problem boils
down to the question what is the common topic uniting all the four
major principles. Aristotle's answer is that as they are principles
required when describing anything there is, the primary philosophy
should study literally everything there is – trees, humans beings,
lakes and everything else. Yet, the primary philosophy should not be
interested of characteristics peculiar e.g. to trees, but only of
characteristics common to all things there are.
What should the primary philosophy
investigate then? Aristotle noted that the phrase ”being” might
well have different meanings – we may say even that there are holes
in my sock, although holes are things of very different sort from
socks. Still, Aristotle thought that we could find some primary
meaning of being, to which all other meanings of the word would be
related. After all, there wouldn't be any holes without socks or
other ”holed” objects – thus, there are clear levels of primacy
among different beings, and presumably, a most primary level of
beings.
A further problematic concerns the
question what are the actual characteristics that are to be found in
this primary level of things. Aristotle himself started from the fact
that – at least in Greek – adding the phrase ”one” added
nothing to the meaning of a word: ”one man” means precisely same
as mere ”man”. Thus, any object studied by primary philosophy
should also be in some sense ”one”: that is, a distinct unity.
Aristotle also recognised that things could be ”one” or same in
many different senses – some things are unified by belonging to
same class, others by having been made of same stuff, that is, by
being the exactly same thing. Furthermore, any discipline studying a
characteristic like unity should also discuss the lack of this
characteristic, which in this case should apparently be plurality,
which also has many senses like oneness. Aristotle then suggested
that all characteristics definable through the concepts of unity and
plurality should be part of the primary philosophy. For instance, a
thing is something else than a given thing, if they are made of
different stuff, and they differ, if they don't have same qualities.
Furthermore, Aristotle stated that the
primary philosophy should also study the primary truths from which
all other truths are to be derived, because these truths should be
valid for all beings. Aristotle does not mean that the primary
philosophy should literally prove these truths, because they in fact
should be presupposed by all demonstrations. Yet, the primary
philosophy could still in some measure at least defend these truths.
Thus, one could defend the most primary truth of them all: that
nothing can both be and not be something at the same time and in the
same respect. Aristotle is not so much concerned of people who deny
this principle in some cases: one might very well say that e.g. an
object looks white and does not look white, that is, depending on the
perspective from which the object is looked at. Even in these cases
people would mostly admit that there is some primary level of
discussion in which the principle does hold – for instance, the
statement saying that an object looks differently coloured from
different perspectives might be true in all contexts, while its
opposite would be false in all contexts.
It is the person denying the validity
of the principle in all cases Aristotle worries most. In effect, the
denial would mean the denial of any absolute standpoint – all
statements would be true in some sense and false in another.
Aristotle himself pointed out that such a position would rule out all
meaningful discussion. Indeed, it would make everything a complete
chaos. Furthermore, it would make all decisions pointless: because I
would always both exist and not exist, it would be just as same if I
just would go and throw myself off a cliff.
The denial of contradictions appears
then to be required at least in some primary level, and similarly
one should accept the statement that all things either have a
characteristic or not, Aristotle continued. True, one could suggest
that the process of changing from one characteristic to another would
constitute a third possibility. Yet, one would still have at least
some definite possible characteristics of which a thing should have
at least one – definitely being something, definitely not being
something and being in a process of changing from one state to
another. The only other possibility would be to accept an
indefinitely numerous set of mediating states – a process from a
state of being something to a state of changing this state, a process
from the original state of being something to the the previous
process etc. Thus, the statement of definite options should be also
accepted at least in some level.
The primary truths apply then at least
to the primary level of beings, but the question is, what this
primary level consists of. The problem is deepened by the ambiguity
in the use of the word ”being”. Firstly, ”being” is used in
phrases like ”this is so and so”, where we affirm that some
statement is true, that is, that certain thing can be characterised
in a particular manner. Yet, true statements are clearly not as
essential as the things that we state something about – statements
are dependent on human beings, while things in general might not be.
Secondly, in a related sense, we might
say simply ”it's this”, when we just apprehend some thing. This
is also a true statement, but true in the sense of coming in contact
with something: an opposite state would not be an assertion of false
statement, but a state of not coming in contact with the thing.
Still, even here the statetement is not as essential as the thing
contacted. Thus, truth in general does not constitute the primary
level of being.
Furthermore, we could speak of a thing
being something accidentally, just like a quack might manage to cure
his patient, if he gets lucky. Such accidences cannot be
systematically studied, just because they are mere accidences – we
cannot say why it was a quack who did the curing, because his
quackness had nothing to do with the curing, and indeed, quacks
usually don't cure people. The primary level is then not to be
identified with any mere accidental features that might change from
one situation to another.
Now, in all changes there is something
that remains same throughout the whole process: for instance, when a
piece of bronze is made into a statue, the statue is still a thing
made of bronze, although its original shape has changed. We might
thus suppose that what remains constant in all possible changes
constitutes the primary level of being. Then again, this constant
element would not be in itself cut into individual pieces, because
this would require a further structurisation of this ”prime
matter”. Yet, it appears evident that the primary entities are
individual things of some sort and thus not a mere shapeless unity of
matter.
It then might appear that structured
pieces of this stable element underlying all changes would fit the
role of primary beings. This is what we actually suppose normally,
because cats, planets and rocks are just such structured pieces of
matter. One could say that even abstract geometrical entities - such
as lines, triangles and cubes – are structured pieces of a stable
space and so also fit this supposed definition of primary level. In
fact, all things that can be defined (e.g. human being) can be
analysed as being further structurations (rational) of a stable
element capable of being structured in several manners (animal). Only
indefinable primary concepts cannot be described in this manner.
The problem is that these structured
pieces are obviously dependent on the stable element and on the
structure. Indeed, the most familiar of these structured pieces are
suspectible to destruction, just as they have been generated, e.g. a
cat is born and dies. The case of generation and destruction actually
suggests that the structures are more stable than the structured
things. In case of living beings, a living being that begins the
process of generating another living being uses some material by
giving it a similar structure to what it itself has, just like a cat
is conceived by other cats. In artificial production, on the other
hand, the producer at least thinks of the structure she wants to
embody and uses the materials for producing this embodiment.
Furthermore, there is the third possibility that something accidental
begins a process of generation, but even then the structured element
must have had a capacity for being structured in this manner. While
ordinary things come and go, their structures remain, and it even
seems meaningless to ask how e.g. a structure of life could be
destroyed.
Aristotle finds other reasons for
upholding the primacy of the structures. People can express wonder
for various things: say, ”cow – sick?”, ”thunder –
tonight?” or ”Madonna – in Moscow?”. These expressions of
wonder, which could be turned into why-questions, have the same
shape: they express wonder of a feature that some thing has. The
wonder might be answered by determining the factor causing the
feature – what made the cow sick or generated thunder tonight –
or by determining the purpose for the feature – for what reason
Madonna chose to travel to Moscow.
Aristotle then noted that one could
also express wonder of the thing itself and not just its feature. In
one sense such wonder is irrational: it is self-evident that e.g.
horses are what they are. Yet, the wonder in this case is explicable
– we are wondering e.g. what makes these bones, blood and other
tissues into a unitary being that we can call a horse. Aristotle
notes that it is simply that these constituents take on a certain
structure, that is, the structure of a horse.
It appears then that it is the
structure that is the most primary constituent: in other words, the
important question is not what something is made of, but what it is
made into, i.e. what its essential nature is. Of course, there are
also secondary structures. Hence, we could speak of the structure of
whiteness and we might even find a suitable definition for something
being white. Yet, just like such accidental features are not beings
in the primary sense, also only the things of primary level have a
structure in a much stronger manner.
Furthermore, individual things cannot
really be captured merely by their structure, because in addition to
their structure, the things have also the material from which they
have been made. Of course, we could add to the definition of a thing
the material, but this would still not individuate the thing enough –
even if we would have two structurally identical statues made of
bronze, they both would still be made of a different pieze of bronze
and would still be different things.
Structures thus appear to be something
that could be shared by a number of things, but this has its own
problems, because the primary things are usually thought as
individuals. One possibility might be to assume that the structures
would be indeed independent individuals, which would somehow make
material objects assume shapes resembling themselves, somewhat like
in Plato's theory of ideas. Yet, Aristotle at once points out the
dilemma that such an assumption just begs the question: what then
structurises these supposed ideal structures?
Aristotle's final answer is that the
primary level of beings depends on the context. The stable element
common to various things has the capacity to become any of these
things, just like bronze can take various shapes. When the capacities
are activated, a certain concrete thing is generated, and when the
activating element is removed, the concrete thing is destroyed –
thus, we might say that a shapeless blop of bronze is less primary or
less active than a statue made of it. Finally, what makes the stable
element into a concrete thing and thus activates its capacities is
the structure. One might still ask what then combines the stable
element and the structure. Aristotle's answer is that they just are
defined as being necessary complements to one another: the stable
element has the capacity to be structurised in some manner, if
suitable external influences affect it, while the structure is just
the activation of this potential capacity.
Because the components of the primary
level are explained through concepts of potential capacity and its
activation, Aristotle accordingly proceeds to analyse these terms. He
notes that potentiality in Greek means primarily something that can
be changed by some external element, just like a piece of bronze can
be sculpted into a statue. More generally even things that cause
changes may be said to have potential capacities, just like fire has
the capacity of burning a forest.
In many cases, capacities belong to
inanimate things or to animals incapable of choosing their own
actions. Such capacities can only be passively activated by suitable
circumstances, just like fire grows when oxygen is present and a
starving animal starts to salivate when it senses food. Then again, a
free agent with a capacity – say, a doctor – can choose not to
use her activities and might even use it for contrary purposes, just
like the doctor might use her medical knowledge for killing a person.
When does then a thing have a capacity
for something? Megarian school had suggested that a thing had
potential capacities only when it truly used them. Aristotle noted
that this idea would lead to obvious absurdities: whenever we were
not doing sums, we would lose our capacity for arithmetic. Aristotle
himself noted that some capacities were inherent in natural
properties of some things, just like eyes have the capacity for
seeing. Then again, acquired capacities were usually received in
whole when one for the first time used them, just like a practicing
architect could be said to have the capacity for building only when
she has built a house.
In rare cases Aristotle accepts
capacities that do not have a corresponding actual result, for
instance, a capacity for infinite divisibility of matter can never be
wholly activated, because there is no final point at which the
divisibility would end. Most of the time, an activation of capacity
results in something that differs from the capacity, but also from
the process of activation: this process is limited by the actual
result. The result might be a thing generated through the activation
of the capacity, such as a house made by an architect. In more
important cases, the result of the activation is itself an activity,
just like the activation of generative processes of life causes the
beginning of a new process of life of a living individual. Such an
activity would have no external end it would try to acheive, unlike
the process of activation.
Aristotle notes that we cannot really
speak of the capacity without mentioning the result of its activation
– capacity of sight is just a capacity for seeing something. Then
again, the result can be mentioned without mentioning the capacity.
In general, the result is more essential than the capacity: the
capacity is desired for the sake of acheiving the result, and not the
other way around. True, capacities do appear to be prior in time,
because one must have the capacity, before one can activate it. Yet,
the result must often exist before the capacity in another
individiual thing – thus, although a fetus might have the capacity
to become a horse, the fetus itself is preceded by other horses which
have conceived the fetus.
The primary level of being has thus
been discovered, but it is not yet clear what classes this primary
level is divided into. We know already from the Aristotelian physics
that there are things that have a tendency to change in various ways,
when left to their own devices. Some of them, the earthly things,
changed in an irregular manner, while the celestial objects appeared
to move eternally in a constant manner. An interesting problem lies
in the question whether only those things studied by the physics
exist: if this would be so, the primary philosophy would be only the
most general stage of physics.
Aristotle does appear to accept beyond
physical things also mathematical objects, which cannot be physical,
because the do not change their nature – a triangle has always
three sides, as long as it is a triangle. Yet, these objects cannot
really be independent objects, because then the connection of
mathematics with actual triangles would become incomprehensible.
Instead, objects of mathematics are only physical things, when we
disregard their material substrate and consider only their geometric
form and quantity – there is no abstract heaven of triangles, but
only actual triangles, which can e.g. change their shape. Other
possible candidates for non-physical or invariable objects would be
Platonic ideas. Yet, accepting such objects as independent of the
natural things causes several problems, for instance, it
unpurposefully adds a layer of objects beyond what we can see and
hear.
Still, the eternal motion of stars does
require something beyond mere physical things that will keep the
heavenly spheres moving – and the stars must move eternally, or
otherwise we must presuppose a sudden point of time in which
everything in the world started inexplicably. Even a mere potential
capacity for moving the stars would not be sufficient, because such a
capacity might accidentally stop working. Instead, this moving
principle should be constantly active in the same manner.
Because it cannot then change its
state, it must be in the most perfect state possible for it and
indeed for anything. Yet, it would still be constantly active, but
its action would have no other goal beyond its own self-satisfaction
– the perfect thing would live in an enduring orgastic moment.
Aristotle suggested that the nearest we can ever come to feel the
same as the perfect thing is when we without any external purpose
think some fairly abstract philosophical issues and take pleasure in
our capacities for handling such difficulties.
Aristotle deplored the idea that this
epitome of perfection would go on turning the crank that moved the
universe: this would make it seem like this perfect thing or God
would want something by causing the movement happen. Instead, the God
does not will to move the universe, but merely inspires the universe
to move with its very existence – it is so perfect that the sphere
of the stars tries to imitate it by its own constant movement, and
from the heavens the movement the passes to Earth.
Aristotle also appeared to waver in the
question, whether there are only one or more of these perfections. On
the one hand, all the planets appeared to need their own governing
principles that kept their movement going on. On the other hand,
there are various difficulties in accepting more than one perfect
being. The sensible things can be differentiated at least through
their different matter: even two pieces with the same structure can
be made of different materials or at least different pieces of the
same stuff. Now, material of structures was to be analysed in terms
of potential capacities: bronze is just something that can be used
for brazwn objects. But the perfect being would have no
potentialities and thus it could not have any individuating matter.
Hence, it appears that there could be only one perfect thing.
Whatever the case, the perfect being
would be the apex of a hierarchy based on the notion of perfection,
high above mere mortals. Indeed, this perfect being would be the
source of all perfection and goodness in the world – the perfect
thing inspires others. So, the primary philosophy lies in close
connection with these theological speculations – all beings receive
their meaning from the perfect being.
