The latest evolutionary phase in programming is OOPS (Object Oriented Programming Systems). Objects are modules which encompass both data and instructions in self contained units. The user communicates with the functions performed by these objects - but not with their structure and internal processes.

Programming objects, in other words, are "black boxes" (an engineering term). The programmer is unable to tell how the object does what it does, or how does an external, useful function arise from internal, hidden functions or structures. Objects are epiphenomenal, emergent, phase transient. In short: much closer to reality as described by modern physics.

Though these black boxes communicate - it is not the communication, its speed, or efficacy which determine the overall efficiency of the system. It is the hierarchical and at the same time fuzzy organization of the objects which does the trick. Objects are organized in classes which define their (actualized and potential) properties. The object's behaviour (what it does and what it reacts to) is defined by its membership of a class of objects.

Moreover, objects can be organized in new (sub) classes while inheriting all the definitions and characteristics of the original class in addition to new properties. In a way, these newly emergent classes are the products while the classes they are derived from are the origin. This process so closely resembles natural - and especially biological - phenomena that it lends additional force to the software metaphor.

Thus, classes can be used as building blocks. Their permutations define the set of all soluble problems. It can be proven that Turing Machines are a private instance of a general, much stronger, class theory (a-la Principia Mathematica). The integration of hardware (computer, brain) and software (computer applications, mind) is done through "framework applications" which match the two elements structurally and functionally. The equivalent in the brain is sometimes called by philosophers and psychologists "a-priori categories", or "the collective unconscious".

Computers and their programming evolve. Relational databases cannot be integrated with object oriented ones, for instance. To run Java applets, a "virtual machine" needs to be embedded in the operating system. These phases closely resemble the development of the brain-mind couplet.

When is a metaphor a good metaphor? When it teaches us something new about the origin. It must possess some structural and functional resemblance. But this quantitative and observational facet is not enough. There is also a qualitative one: the metaphor must be instructive, revealing, insightful, aesthetic, and parsimonious - in short, it must constitute a theory and produce falsifiable predictions. A metaphor is also subject to logical and aesthetic rules and to the rigors of the scientific method.

If the software metaphor is correct, the brain must contain the following features:

  1. Parity checks through back propagation of signals. The brain's electrochemical signals must move back (to the origin) and forward, simultaneously, in order to establish a feedback parity loop.
  2. The neuron cannot be a binary (two state) machine (a quantum computer is multi-state). It must have many levels of excitation (i.e., many modes of representation of information). The threshold ("all or nothing" firing) hypothesis must be wrong.
  3. Redundancy must be built into all the aspects and dimensions of the brain and its activities. Redundant hardware -different centers to perform similar tasks. Redundant communications channels with the same information simultaneously transferred across them. Redundant retrieval of data and redundant usage of obtained data (through working, "upper" memory).
  4. The basic concept of the workings of the brain must be the comparison of "representational elements" to "models of the world". Thus, a coherent picture is obtained which yields predictions and allows to manipulate the environment effectively.
  5. Many of the functions tackled by the brain must be recursive. We can expect to find that we can reduce all the activities of the brain to computational, mechanically solvable, recursive functions. The brain can be regarded as a Turing Machine and the dreams of Artificial Intelligence are likely come true.
  6. The brain must be a learning, self organizing, entity. The brain's very hardware must disassemble, reassemble, reorganize, restructure, reroute, reconnect, disconnect, and, in general, alter itself in response to data. In most man-made machines, the data is external to the processing unit. It enters and exits the machine through designated ports but does not affect the machine's structure or functioning. Not so the brain. It reconfigures itself with every bit of data. One can say that a new brain is created every time a single bit of information is processed.

Only if these six cumulative requirements are met - can we say that the software metaphor is useful.

Part 2 Psychology and Psychotherapy

Storytelling has been with us since the days of campfire and besieging wild animals. It served a number of important functions: amelioration of fears, communication of vital information (regarding survival tactics and the characteristics of animals, for instance), the satisfaction of a sense of order (justice), the development of the ability to hypothesize, predict and introduce theories and so on.

We are all endowed with a sense of wonder. The world around us in inexplicable, baffling in its diversity and myriad forms. We experience an urge to organize it, to "explain the wonder away", to order it in order to know what to expect next (predict). These are the essentials of survival. But while we have been successful at imposing our mind's structures on the outside world - we have been much less successful when we tried to cope with our internal universe.
