OK, I was wrong on this one, I can see this now. I should have thought
First, a side point. To avoid confusion. The Webmind AI Engine does
not use predicate logic at all; the parts of it that are logical in nature
use a special kind of uncertain term logic.... Furthermore it has a special
representation for procedural knowledge -- "schema" -- which is different
but can be translated into, the declarative logic.
Second, my main point before should have been stated like this: If a
philosophy is defined as
-- a state of beliefs about the world
-- a habitual set of ways of acting towards the world.
then any system with a sufficiently flexible way of representing declarative
knowledge and representing and enacting procedural knowledge, can embody any
My statement about HOPL before was restricted to belief, and incorrectly
But anyway, I guess this statement is of limited value, because it's a
which doesn't take into account real-world computational restrictions. So
only applies to superpowerful supercomputer programs in the future.
For instance, any program that can enact the procedure of emptying out its
can in some sense meditate. But it may not be constructed to as to get the
same thing out
of meditation as people do. So in order to really embody Zen, it would have
the human mind's type of STM dynamics. Which requires a superpowerful
supercomputer level of
So, I guess my initial statement was wrong. This issue really is a bit like
After the Singularity, systems may be mutable enough to adapt their
psychologies to adopt any
philosophy. But by giving them the right philosophy pre-Singularity, the
philosophy may be strongly influenced.
But what is "the right philosophy" :>
