Deutsch is right about the need to advance in Popperian epistemology,
which ultimately is evolutionary epistemology. How evolution makes a
portion of matter ascertain what is truth in virtue of what and for
what purpose. The idea of intelligence need a knowledge of what is
truth but also a motive for acting and therefore using this
intelligence. if there is no purpose there is no acting, if no act, no
selection of intelligent behaviours if no evolution, no intelligence.
Not only intelligence is made for acting accoding with arbitrary
purpose: It has evolved from the selection of resulting behaviours for
an ordinary purpose is non separable from other purposes that are
coordinated for a particular superior purpose, but the chain of
reasoning and actng means tthat a designed intelligent robot also need
an ultimate purpose. otherwise it would be a sequencer and achiever of
disconnected goals at a certain level where the goals would never have
coordination, that is it would be not intelligent.
This is somewhat different ffom humans, because much of our goals are
hardcoded and non accessible to introspection, although we can use
evolutionary reasoning for obtaining falsable hypothesis about
apparently irrational behaviour, like love, anger aestetics, pleasure
and so on. However men are from time to time asking themselves for the
deep meaning of what he does. specially when a whole chain of goals
have failed, so he is a in a bottleneck. Because this is the right
thing to do for intelligent beings. A true intelligent being therefore
has existential, moral and belief problems. If an artificial
intelligent being has these problems, the designed as solved the
problem of AGI to the most deeper level.
An AGI designed has no such "core engine" of impulses and perceptions
that drive, in the first place, intelligence to action: curiosity,
fame and respect, power, social navigation instimcts. It has to start
from scratch. Concerning perceptions, a man has hardwired
perceptions that create meaning: There is part of brain circuitry at
various levels that make it feel that a person in front of him is
another person. But really it is its evolved circuitry what makes the
impression that that is a person and that this is true, instead of a
bunch of moving atoms. Popperian Evoluitionary epistemology build from
this. All of this link computer science with philosophy at the deeper
Another comment concerning design: The evolutionary designs are
different from rational designs. The modularity in rartional design
arises from the fact that reason can not reason with many variables at
the same time. Reason uses divide an conquer. Object oriented design,
modual architecture and so on are a consequence of that limitation.
These design are understandable by other humans, but they are not the
most effcient. In contrast, modularity in evolution is functional.
That means that if a brain structure is near other in the brain
forming a greater structuture it is for reasons of efficiency, not for
reasons of modularity. the interfaces between modules are not
discrete, but pervasive. This makes essentially a reverse engineering
of the brain inpossible.
