--------------------------------
6.1 Consciousness, p 56
(Note:
 blindness.) 
Practical engineers try to exploit the use of signals that
already have acquired some significance.

6.2 Signals and signs, p 57
[Explaining analogy. EXIT sign on a 'non-door' would make it
usable]

6.6 Momentary mental time, p 61
[Message driven model! (with communication delays)]

6.9 Heads in the clouds, p 64
How useless any thought would be if, afterwards, your mind
returned to the selfsame state.
It's almost always wrong to seek the "real meaning" of anything.
A thing with just one meaning has scarcely any meaning at all.

6.10 Worlds out of mind, p 65
["Natural worlds"] are far to vast to comprehend -except where
we impose on them the rules we make [grammar rules and traffic
laws]. Note:
 prescription.

[...] the mind has [...] found a way to simplify  itself. [...]
what we must suspect whenever some idea seems to explain too
much.

One can acquire certainty only by amputating inquiry.

6.11 In-sight, p 66
One cannot use data [signals from the brain] without having at
least the beginnings of some theory or hypothesis.

6.13 Self-knowledge is dangerous, p 68
Every learning machine must have the same protective scheme [we
get bored by doing the same thing over and over].
If we could [...] reproduce the pleasure of success without the
need for any accomplishment [...] that would be the end of
everything.
