His Metaphysical Vision
Leibniz truly believed in a
system of clear human reason or logic which could elevate human life beyond
the narrow, mean-spirited ways of his strife torn world (the Catholic-Protestant
wars and the monarchical ambitions of the German, French, Spanish and other
kings and princes made life in Europe very dangerous). He believed
that it was possible to create a mathematically pure system of theological
and political thought such as would bring the world to a fully reasoned
existence. His early work in the studies of law and his later work
in the field of mathematics where strongly motivated by this vision.
In accordance with this vision he set out to construct a metaphysics of
such clarity and precision that it might become the foundation for a new
world order.
The Monads--and God
Leibniz was highly opposed to
the Newtonian cosmology of absolute matter, space and time. In distinction
to Newton's theory of material substance, founded on the the atom and its
placement and movements, Leibniz proposed
monads as the foundation
of all reality. Leibniz' monads interestingly had no material existence--no
placement in time and space, no velocity or direction of movement.
His monads were more like what we would today call potential energy--each
monad being distinct in its potentiality, each monad being a part of a
larger "colony" of monads which, through the directives of God, combined
in distinct ways to form the observable parts of our universe.
God (alone) knows the potential
of every monad and knows how the world is to look as a result of how these
monads are brought together by him in various combinations to produce the
harmony of life or existence.
These single monads are not
mere Newtonian pieces of the larger cosmic puzzle, but are each tiny mirrorings
of the entire universe. Each monad has the capacity or potential
to express the fullness of the universe built through the relationship
of all the monads with each other--though the particular expression or
mirroring of each monad represents only a single view or perspective--the
view from where it sits in relationship to the whole picture. Only
God alone has the capacity to see the whole picture--from all perspectives
simultaneously. Only God alone has the capacity to choose which of
these views or visions will be the one that comes into actual being--through
an "unfolding" of the potential of the multiplicity of monads into the
harmonious actuality of their God-ordained behavior.
This is to say that only
God alone has the power to move this whole picture forward from potential
to fulfillment. The universe is entirely dependent upon God for its
actual existence--its movement from potential (from a virtually infinite
realm of possibilities) to the actual. It is not, as Newton's world
was, "auto-deterministic" or self-running in accordance to some absolute
plan like a well wound-up clock or some kind of perpetual motor moving
in accordance to the laws that describe, dictate or direct its actions.
Leibniz' world did not result
from a rule of physical cause-and-effect. One monad did not spur
another monad into being--like a billiard ball hitting other billiard balls
and setting off a round of cause-and-effect movements. Each monad
was independent, automonous. The linkage among the monads was entirely
through the design of God by which each monad moved from potential to actual
by God's separate and harmonious design of all the monads working
together.
Thus not only was Leibniz'
cosmos not self-running (as Newton saw things), it was not even truly existent
apart from the "intervention" from God. For Leibniz: "No God--no
universe." God was totally necessary to Leibniz' world--not just
as the original architect (as Newton acknowledged God) but as the actual
sustainer of all existence, all substance, all being, all "time," all events.
God
Who was/is this God? God
is the necessary being that stands outside the realm of monads--beyond
the realm of merely potential being. God alone is full being.
Further, God is the necessary cause of all that is--in the "contingent"
world of monads. God alone is not caused. God alone is
not dependent on anything else for his own "existence." God alone
causes "contingent" existence--and not just "in the beginning" (as with
Newton) but in all time and in all places and situations. Apart from
the actions of God, indeed, there would never be such things as time, places,
situations.
God is the "intellect" of
the universe, which everything else in the universe (all the monads) mirrors,
in full--but in relative form.
Necessary Truths and Contingent
Truths
Necessary Truths.
Necessary truths are those truths which are so by logical definition.
For instance the phrase, "a senior citizen is any elderly person."
How do we know this is true? It's true because we have said it was
true, by the very definition of our terms "senior citizen" and "elderly."
These are thus truths "by necessity."
Other forms of necessary
truths are: "a circle is a perfectly round line"; "a square is an
area enscribed by four straight lines of equal size meeting at right angles
to each other"; "8 + 3 = 11." These are true because we have ourselves
defined the word "eleven" to mean eleven and not ten--or because we have
given the name "circle" to the round object and the name "square" to the
boxy object. We could have reversed the words and taught ourselves
to see them accordingly--even teaching our children to use these words
in this new way and it would not change anything about reality. We
are only talking about things that are "true" by common definition.
If you change the definitions you only are changing our vocabulary, our
terminology--not the reality of the things in themselves.
Some people when asked what
color the sea is might say "green." Others might say "blue"
There is no point in arguing which of these statements is true, because
they are true by definition--that is by how a person defines the boundaries
of blue or green--especially where they meet each other on our personal
color charts!
This arbitrariness is the
very essence of all things that are true by definition, by necessity.
Contingent Truths.
Also--this necesary truth which is true by very definition or necessity
has no cause and effect to make it true, such as "if you go out in the
rain you will get wet." The latter kind of truth is a truth of fact,
a truth of science, a "contingent" truth. It is true because something
"causes" it to be true. A contingent truth is a very different
order of truth than a necessary truth.
In our modern thinking, every
event supposedly has its particular "cause," something that caused it to
be or to happen. We are not merely interested in the necessary truth
that "Johnny is wet." If we were Johnny's mother, we would certainly
want to know why Johnny is wet. We would be interested in
the contingency of his wetness--that is, the realm of cause-and-effect
about his wetness. (But Johnny himself in the face of such a question
might speak up: "Aw Mom, I'm not wet, I'm just a little damp."
He is offering up a necessary truth when his mother is looking for
a contingent truth: "how did you get this way?")
The thing that characterizes
modern culture is our preoccupation with contingent truths. We want
to know why things happen. We're like one of two people gazing
at a setting sun across a lake, blanketed by clouds of hues of pink and
orange and even red. One person might be thinking "how beautiful
this all is" (a truth by necessity). But we westerners would be too
busy to notice such beauty because our minds were working on the thought:
"why do these colors occur as they do; what causes the red, the orange
and the yellow?" We don't just want to receive the truths of the
events. We want to master those truths. And so we busy our
thoughts with the quest for contingent truths. We are of a scientific
bent or nature!
Anyway, it is this realm
of cause and effect truths that our modern, western, "empirical" science
is designed to explore. In the end, such science hopes to be able
to provide an explanation for everything that happens under the sun--in
terms of the causes of all things.
The ultimate contradictions
inherent in contingent truths. The difficulty, however, of trying
to describe life, the very universe, through such truths of fact or contingent
truths is that there is no end to their contingency. If everything
has a cause there can be nothing that has no cause. And yet something
has to start the series of cause-and-effect off. By this very logic
of cause-and-effect there can never be some kind of ultimate starting point,
a point at which things simply are, without a cause. And yet the
process of cause and effect necessarily requires some kind of a starting
point, one which would be the ultimate cause of all other causes.
Thus this logic cannot, because of its need to explain all events in terms
of their cause, provide any kind of explanation of this most important
of all causes: the first cause! At this most critical of points in
its line of logic, its very logic breaks down!
Thus without being able to
provide an explanation for first causes, there can be no true logic to
such a science. Indeed, all that factual or contingent science can
do is to study the appearances of events, and their apparent
causes. It cannot truly find the ultimate cause of anything.
Leibniz and the ultimate
source of all truth in God. Leibniz understood that all truths
ultimately point back in their contingency to the same ultimate cause:
God. It is God that sets off the course of all events. Everything
is contingent upon his being, his thoughts, his will. Unless you
can factor God into the picture you have offered no explanation whatsoever
about the cause of things!
Yet when you come back in
your logic to God, you are no longer talking about contingent truths--because
from the point of view of God all things have their truth "by necessity."
They are what they are and do what they do simply because God defines them
to be/to act that way.
Remember that Leibniz understood
that every monad had the potential to become everything. It is only
by the choices of God that they become what they actually become--they
become so by the arbitrary decisions or judgments of God. Through
the will of God they take the ultimate course that they do.
But you can never say why
God caused these things to take place as they do. Who could ever
claim to know the mind of God? To Leibniz, all we can do is describe
events--not explain them.
