This page is about the question how the various
 +
phenomena of mind emerge from the interactions of many mindless
 +
agents. The term '''Society of Mind''' has been coined by
 +
Marvin Minsky. Bateson's idea of an [[Ecology of Mind]] and
 +
Minsky's idea of a "Society of Mind" have much in common.
 +
Both are similar because they try to describe a whole system of
 +
interacting entities - species for ecology and agents for society.

At least we can try to model consciousness, pleasure/joy, displeasure/pain,
 
-
humor, insights and other emergent phenomena with agent-based systems or
 
-
multi-agent systems. This page is about the question how the various
 
-
phenomena of mind emerge from the interactions of many mindless

agents.

== Are there any friends, families or social networks ? ==
 +
 +
Yes, there are. And they are important.
 +
Daniel C. Dennett writes in his book "Brainchildren -
 +
Essays on Designing Minds", (Penguin Press Science, 1998)
 +
 +
: "In ordinary runs of affairs, large families of beliefs travel together in our mental lives. At one instant, Mary believes that her purse in on the bed, and believes her handbag is on some horizontal surface, and believes that the item containing her comb is supported by the article of furniture one sleeps in, and so forth. Now do all (or many) of these distinct states have to light up and team up to cause Mary to run upstairs? Or is there just one each from the belief family and the desire family that are chosen to do the work?"
 +
 +
The 'society of mind' metaphor becomes interesting if we
 +
consider the [[Social_network|social networks]] inside the society. The value
 +
of the human mind lies in its vast network which connects
 +
the individual agents. To illustrate this point, Marvin
 +
Minsky compares in section 4.3 "The Soul" of his book
 +
"The Society of Mind" the mind to a painting:
 +
 +
: "The art of a great painting is not in any one idea, nor in a multitude of separate tricks for placing all those pigment spots, but in the great network of relationships among its parts. Similarly, the agents, raw, that make our minds are by themselves as valueless as aimless, scattered daubs of paint."
 +
 +
Relationships exist for example between agents which
 +
represent similar objects or situations, or between
 +
agents of the same function.
 +
According to the BDI model one can identify a belief family,
 +
a desire family and an intention family, as Dennett does.
 +
Friendships exist if there are any analogies and
 +
metaphors (see below).
 +
 +
The social network as a whole is of fundamental importance,
 +
because it offers a solution to the [[Hard problem of consciousness|hard problem of consciousness]]:
 +
'''the social network of the mind determines the kind of subjective experience.'''
 +
Everyone has a uniqe “society of mind”, and a unique social network.
 +
Each of us is adapted to a slightly different world (or different “slice”
 +
of the same world). Already William James said
 +
 +
: "The peculiarity of our experiences, that they not only are, but are known, which their ’conscious’ quality is invoked to explain, is better explained by their relations – these relations themselves being experiences – to one another."

The basic idea is simple. Agreement is good, disagreement is bad.

+
Agreement among the agents in the society of mind is associated with
-
Contradictions between agents, for example  
+
pleasure. '''Pleasure''' is a state of physical integrity and
 +
effortless '''action readiness''' of the body. The body signals
 +
that it is ready for work, that there are no obstacles or objections
 +
for action. It is reflected by an internally consistent representation
 +
(no contradictions, consonance, agreement). On the contrary,
 +
'''pain''' is a state characterized by '''violation of the physical integrity'''
 +
of the body. The body signals that some actions should be
 +
avoided, or that it is tired and depleted. This state is
 +
reflected by an internally inconsistent representation
 +
(contradictions, dissonance, disagreement).
 +
 
 +
This model means that physical integrity of the body is
 +
connected to the "mental integrity" of the mind.
 +
In general, conflicts between agents are bad, while consensus is good.
 +
Conflicts represent a situation of [[Cognitive dissonance|cognitive dissonance]].
 +
They are unpleasant for the mind, society or population,
 +
because it means tiresome inhibition or deactivation of

agents. Contradictions between agents, for example

the term [http://en.wikipedia.org/wiki/Collective_consciousness collective consciousness]
 
-
in societies refers to the shared beliefs and moral attitudes which operate
 
-
as a unifying force within society. Religion plays an

important role in uniting members through the creation
 
-
of a common consciousness, just as the belief in the
 
-
own self plays an important role in building a consistent
 
-
single personality. The belief in a god is not that
 
-
different from a belief in an own [[Self|self]].
