Any result of the simulation on a model is a truth associated to that model.
As pointed out in the general theory, a truth is associated by us to a
symbolic message (generated by a symbolic model); however in order to keep the
terminology simple, in the case of image models, a result obtained by
simulation on the model is also called 'truth', in spite of the fact that it
is used 'as is', without the necessity to explain it.
Example: If an animal builds an image model of the external reality,
predicting a dangerous situation, it is possible to find the solution to the
problem by simulation on the model. This solution (the truth) might be, e.g.
to flee. The truth will activate directly the preexistent action model, which
is in this case to flee.
We'll refer from now on only to symbolic models. If no model is specified, any
truth is nonsense.
Example: The truth is ãa car crashed into a wall". This truth might be
generated by any of the following models:
-accident
-test
-movie/cartoon
-computer game
In any of the above models, the specified truth is interpreted differently (it
has a different meaning).
The theory underlines thus, that the model which generated a truth needs to be
specified and accepted before the presentation of the truth. This basic
requirement is always met in positive sciences.
In common life, the declaration of the model is not always done, and often the
model does not even exist in an elaborate and coherent form. Emerging from
here a long line of conflicts between individuals, groups or cultural zones,
which all have their own reality associated to the same external reality. This
can be interpreted as a design deficiency of the brain. Some can compensate
this hardware deficiency by software, e.g. the individuals situated on level 3
of consciousness (see the general theory).
There is a fairly common situation in external reality when a person states a
truth, and then builds the model to support it. This happens usually for
persons based on image models only, and when they interact with external
reality, they only translate the image truth to a symbolic truth. Such persons
are recognisable by their rudimentary logic and their tendency to fragment any
discussion to particular sections of the external reality. Such persons can't
discuss a single general subject.
Exercise: Verify yourself and others on the existence and status of the model,
which generated any stated truth.
It is known from the general theory that a basic problem in the construction
of a model associated to the external reality is that we do not know
beforehand the elements of the specific external reality. These elements need
to be discovered, and the discovered elements are the only ones we can operate
with.
Warning: The external reality, as defined in MDT, can't have elements and
relationships. The elements and relations appear only in the model associated
to the external reality. However, in many statements we will use notions like
elements and relationships of the external reality, but these need to be
understood as elements and relations of the model associated to the external
reality. For the external reality, one can use the term 'entity', which
identified by the model will become an element of it. However, we have no word
available to associate to external reality in the case of relations. By
perfectioning the language, such deficiencies will be solved.
A basic requirement for the existence of communication is the existence of a
single common model accepted by both parts who want to communicate. Without a
common symbolic model, there is no communication, as both sides will have
their own list of definition of the terms associated to the words.
Usually, communication is done only on symbolic models. However, there are
more primitive forms of communication using image models (between people,
between humans and animals, between animals).
The reality is defined in the general theory as the sum of all truths
generated, or possibly generated, by a model. As each person has his/her own
collection of models, the reality as understood by each person is different
from one person to another.
It is important to specify that in the domain of positive sciences,
fundamental models generally accepted do exist. One of these models is e.g.
Newton's Mechanics. As this model generates a reality, all physicists consider
that the 'reality' is the one generated by Newton's Mechanics, within its
limits of applicability.
Due to reasons associated to confusions of the science of knowledge, the
reality generated by Newton's model is considered as 'objective'. Thus,
"objective reality" is a term generated by a generally accepted model in
specified conditions. From this point of view, the fact that the Sun revolves
around the Earth is an "objective truth", at least at the level of the year
1500.
It needs to be stated by all means that without a model, the external reality
cannot be perceived. After building a model associated to the external
reality, what we perceive is what the model states as perception. If, e.g. we
say that 'snow is white', this is the result generated by a model associated
with external reality, external reality which contains the element 'snow'. One
of the properties of the element 'snow' is that it is white. Under the
microscope (another model) the same snow looks transparent.
As we already mentioned, reality is the one generated by the model associated
to a given external reality. Each time we state a truth, we have to specify
first the model.
Example: There are an A and a B person. A is taller than B, as it results from
measurement. The term 'length' is generated of the model 'space', as Euclid's
Geometry and Newton's Mechanics understand it. These fundamental models
characterize this truth as objective. If we say that "A is more attractive
than B", this is a subjective truth. However a model has also generated this
truth, more or less elaborate/ specified and more or less accepted by
different persons.
The conclusion is that the term 'subjective truth' is resulting from a model,
which is not unanimously accepted or insufficiently elaborated. In this case,
it is clear that people should avoid such truths or should declare the model.
With the evolution of thinking, the term 'subjective truth' will be removed
from the thinking system.
