The problem with deductive logic is that all the premises can be true and follow from one to the next all the way to the end. That doesn't mean that the conclusion derived from the process has any relationship to reality. In other words, you can have complete internal consistency and still be wrong. Life requires both kinds of reason.
I like your definition. I think it's pretty simple and might work. Cuts through the crap nicely, too. I think the definition of Te as "business logic" places capitalistic meanings into the definition of the function, when it might be possible to have anti-capitalistic people with strong Te. So Te must be something other than business logic, @
Crystal. And that term misleads people unintentionally.
This example brings me to my next point: it's things like calling Te "business logic" that lead to inaccurate typings, because people are not really looking at what the function's true nature is, but rather a term that's been assigned to it. @
domr's example shows how abstract the functions really are, and so really include a much wider variety of people than we think.
