- >Rick, could you say a bit more about the relative tradeoffs of using "real"
- >languages like Pascal and C compared to HyperTalk?
-
- I'm getting pretty hyper on the possibilities of HyperCard for control
- experimentation and demonstration. The new version of HyperCard plus
- the faster Macs (IIci,IIfx) makes it feasible to produce the kind of
- experiments we like. I think HyperCard could be used to easily reproduce
- most of the experiments in the "Mind readings" book. Hypertalk is pretty
- easy to learn and use; HyperCard eases much of the user interface
- aspects of programming. The BIG downside of HyperTalk is the lack of
- array variables -- but it is always possible to go to XCMDs (which I've
- never used) when you need this stuff. I think you could do your melody
- control experiment in HyperCard -- but maybe someone else could comment
- on this who has used sound with HyperCard -- I haven't.
-
- I think that, for people with Macs, HyperCard will be a VERY accessible
- way to present and develop PCT demos. But for the "real" bigtime
- stuff (like Powers' ARM and Taylor et al's LITTLE BABY) you need the
- power and speed of serious languages (like C).
-
- I will send you (Gary) a BinHex version of the Conflict stack so
- that you can get an early view of (what I see anyway as) the enormous
- possibilities of HyperCard for making PCT PHENOMENA accessible to
- the Mac community.

- Sorry -- the "total insanity" thing was meant to be a joke; I
- apologize for any suggestion of insult; there was none intended.
-
- I think you took my post as being hostile to certain beliefs.
- You say:
-
- >When it comes to religious beliefs, it is obvious
- >where your bias is concerning the Christian tradition (and other
- >traditions as well).
-
- My only bias concerning the Christian tradition (belief?) is that
- it is a belief. The point of my posts was not to disparage any
- particular beliefs (in fact, I think I've said on several occasions
- that I happen to find many of the Christian beliefs quite attractive --
- such as the belief in a forgiving savior; just to prove that I can be
- an equal opportunity offender regarding beliefs, I'll take the risk of
- raising Oded's ire by saying that I find the jewish belief in their own
- "chosenness" quite unattractive). The point was simply that these
- beliefs ARE BELIEFS (by my definition of belief). I agree that PCT
- is also a belief in this sense; but it is a special kind of belief
- that can be turned into a working model whose behavior can be
- compared to that of real systems; you can see whether this belief
- produces the perceptual results you expect.
-
- I think it is EXTREMELY important to try to clarify the difference
- between a belief like "christ died for our sins" and one like "a
- system in a high gain negative feedback relationship with it's
- environment controls its perceptions". I think there is a BIG difference
- between these two types of beliefs -- and I don't think it's that
- one is "better" than the other. I think it has something to do with
- the fact that the former exists ONLY as imagined perceptions; the latter
- can exist as actual experienced perceptions.
-
- >But what
- >you claim to be total insanity, I claim to be in large part, boss
- >reality.
-
- I love you, Ed. But this is the kind of thing that makes belief scarry
- to me. I claim that "believing" some things is total insanity -- like
- the belief that vulcan is up there on mount olympus making lightning
- bolts or that god sent a non-descript bunch of nomads a tablet with the 10
- "rules of life for everyone " written on them. These are beliefs -- and
- they're fine. But what is it about them that informs you about boss reality?
- More importantly, what is wrong with these beliefs if they are JUST BELIEFS???
-
- Best regards
