A natural mind is an emerging system that shares the following properties with a cyclone:
- has a lifetime
- has a center that's defined in space with good accuracy with respect to the center of any other cyclone i.e. they are easy to distinguish from one another
- their spatial boundaries are fuzzy
- their start date is fuzzy
- their end date is also fuzzy but perhaps less so than their start date
Much of this model goes out the window when considering artificial minds implemented and clonable with modern computers.
