Interesting. "It has its own" critique method? Hm. Not quite sure what
that means exactly...
Anyhow, I wasn't suggesting that Parent had a reference to
Grand_parent.critique()

This is typical of static binding as (for example) seen in C++. If you

(overriden meaning the one that did the overriding)

Oh, I see what you mean. From my experience, the methods are passed
down, not referred to from the parent. That is, Parent does have its
own critique method, not a reference to Grand_parent.critique(). So
when Child calls self.advise, it is calling its inherrited copy. Then,
since the inherited Chi
Parent.critique() is calling self.critique(), which has been overriden
by Child.critique() instead of Parent.critique. It makes perfect sense
to me.

Consider the following:
#!/usr/bin/python
#-
class Grand_parent( object ):
def speak( self ):
print 'Grand_parent.speak()'
self.advise()
def advise( self ):
print 'Grand_parent.advise()'
