How do I make a CLOS method private, so it can only be called by
other methods in the same class?

In CLOS, methods are not "in" a class, so there's no notion of methods
being "in the same class". Generic functions invoke methods when the
argument types match the parameter specializers (note the plural).
In general, CLOS doesn't try to implement any information hiding.
SLOT-VALUE, WITH-SLOTS, and WITH-ACCESSORS can be used anywhere (even in
ordinary functions rather than methods). As with the rest of Common Lisp,
the onus is on the programmer to establish and follow programming
conventions, rather than having them be enforced by the language.
