Well Matt,
Some definition does its job in some framework.
But what do you mean does its job, and what is your framework?
You are talking about the useful technical level of some system, but this is only one way to research things.
At this stage my research is based on the 'Why' question, which is in my opinion the most important question in the first stage, where 'How' questions are used at this stage to support the 'Why' questions.
When time passes there are maybe more 'How' questions then 'Why' questions.
And then there can be again a period of big ‘Why’ questions that maybe can lead us to another session of paradigm-changes and so on.
There is no precise law in this evolution process, and we cannot have paradigm-changes without big ‘Why’ questions.
In my opinion, after more then 2000 years of linear and ‘objective’ approach, we have to go deeper then that and include our modern insights in the most fundamental concepts of this language.
For example: Our cognitive abilities to do Math have to be included in any fundamental understanding of any fundamental development, where concepts like Information, Symmetry, Nonlinearity and Complexity are involved with each other by dynamic and flexible non-trivial processes, which are based on our simplest insights about them.
Again, Mutation is the keyword here, where our self-evident perceptions find deeper levels of reasoning/intuition interactions.
If you concentrate, as you suggesting, only in the tactical/practical side of this language, then we have no meaningful dialog between us, because at this stage I am standing in the strategic ‘Why’ zone of my research, where persons like Muddler and Moshek are opened to it, and you are not.

As for your last post, you are so closed that you don't understand how you give us a good example of your inability to understand my well-defined ideas.

(try finding out the thread where he tries to hide the fact he doesn't know what a bijection is).
No problem, you asked for it, you get it.
Dear Muddler, read what is below, and see for yourself Matt's dialog level:
Matt finds a mistake of mine, and he replies:

The whole dialog between ex-xian and me, where I write, by mistake, Bijection (1-1 and onto) istead of Injection (1-1 and not onto):

The sad thing Muddler is that a person like Matt is going to get his Phd. in this november, and then he is going to multiply his attitute by teaching young persons that will have to obey his methodes, if they want their Phd.
