As they describe in the page, when you describe something, you are trying to place it within a general framework.

In trying to describe a domain in an encyclopedia, it does little good to use language specific to the domain. If your reader doesn't know what Biology is, it's little use trying to describe it in terms of Microbiology and Immunology. You have to use more general language.

There are are few words more general and meaningless in our language than "organization".

edit - grammar

i know. when i found that out, i spent half the day on wikipedia trying it out with different pages. so i built a way to automate it :)
