The main model of any brain (human or animal) is the Protection and Survival
Model (PSM). If something (a person, an animal, an object, an idea...) is
included by a person in his/her PSM (as a model, of course), the relation
between that "something" and that person is a love relation. That is, e.g. a
person A includes a person B (as model) in his/her PSM. The person A will
treat person B in the same way as he/she treats his/her legs, hands, eyes etc.
Here we use the convention that A indicates the person who is in love and B is
the person included in the PSM as a model.
The most important love-relation seems to be between a mother and her
children.
As we defined the term "love" the fact that A loves B is totally independent
on the fact that B loves A.
We already described love based on PSM. There is another type of love, which
is not based on PSM. Thus, the person A makes a structure of models which
contains B in about all of them. If B disappears, the models would become
obsolete, which produces a large instability of the structure. The problem
could be solved by another "B" or by a shielding model or by suicide.
Because love is based mainly on image models, about all of the written above
is true for animals too.
13. Happiness, to be happy
MDT considers that there are two basic modes of interaction of the brain with
the external reality: to generate the reality based on the external reality
and to modify the external reality.
Continuous happiness is associated to the status of the brain which builds
action models (ZAMs) based on ZMs-only. That is, to do and want only what is
possible (as ZMs predict). So any activation of a ZAM is a success (ZAM is
able to reach its aims). The happy persons have a big contribution to the
stability of the society, but small contribution to its advance.
We already defined the disharmonic person as the person who builds and
activates ZAMs without taking in account too much the predictions of the ZMs.
Usually such persons are unhappy, but sometimes they are able to reach their
aims and so, at least for a short time, they are in a status of high level
happiness.
