Actually, this is not quite right. For clarity of presentation, we have been allowing a certain amount of confusion between the thing itself, and its name. Really, the frame for Adam would look something like:
frame-27: name: ((Adam)) sex: (frame-2) spouse: (frame-28) child: (frame-29 frame-30 frame-31)(Where the name slot of the frame holds a list of Lisp atoms used to refer to the frame.) However, since using the name instead of the generated atom frame-27 is much clearer, we will continue to do so. One needs to remember that the machine only knows the internal form.
