Oyez, oyez, oyez: Discussant is the Director Dr Oliver Sparrow of

of the Royal Institute of International Affairs, London town, UK.

For a Chiacago Great Books-style synopticon of what OH Graphics & Sound
(a la Apple II GS) is trying to say, we formulate a synopsis thusly.
Dr Sparrow seems to say that the structure of the mind first forms
itself sufficiently to take in percepts, then is either warped or
at least further formed (informed?) by the very percepts, in a
growth-process whereby the emerging mind remains for a while
structurally unaltered, until dyspepsia (indigestion) of strange
new percepts forces a structural shift in the underpinnings of
the mind. (Gee, poor Dr Einstein -- his mind must have been
stretched and restructured to the bending and breaking point.)
Anyhow, Dr Sparrow seems to be formulating a mental perestroika.

Let us skip over some text available in the origin of the thread:

So the mind grows, structurally, by accretion: What you see,
determines *how* you see.

Commentators: Please do not comment on these excerpts alone,
but go back to the full original text as posted by Dr Sparrow.
Afterthought: Mind.Forth AI is at first a rigid structure into
which we must handcraft each extension of the structure, e.g.,
a particular Chomskyan transformational grammar syntax tree.
Whether still in Mind.Forth or in a derivative Mind.Java, etc.,
the AI structure will eventually generalize its own structures
and thus become capable of learning new components of itself.
