Every taxonomy describes the body, describes what it does, describes why it does it.
How does it order the bodies?
How does it order what they do?
How does it order why they do it?
What if there were three different kinds of taxonomies - each according to these three ways of organization?
In what ways would they overlap or be distinct?
What if a body (or a doing, or a why) requires more than one body (or doing, or why) to do what it does or why it does it? How would The Taxonomy be ordered then?
