- Before I read David Tinker's contribution, I almost stepped into the
- "emergent" quagmire. I then debated for a while whether or not I
- wanted to respond to David's message. I just decided against it when
- lo and behold I came across this:

- The rest of his post was equally reasonable, which is why I decided
- not to respond. My gut feeling, though, was that although you might
- be able to use the word casually in the 'Artificial Life' community,
- you can't in general do so. I think I'd recommend strongly *against*
- using the word in this forum unless you spell out what you mean by it
- each time the subject comes up. The reason for my feeling is that for
- many people, emergence still means something like this:
-
- >Actual life displays properties which are not reducible to the

-
- I think the vast majority of scientists now think that this is wrong,
- and so there shouldn't be a word for Kalki's claimed properties any
- more than there should be a word for flying purple people eaters. (As
- an aside, Kalki what evidence do you have to support your assertion?
- If you say "because people haven't been able to perform the reduction
- yet", I'll be disappointed. Not surprised, but disappointed.)
-
- Wherever the potential for this confusion remains, I'm against using
- the word. Anybody else?
