Python is a language for manipulating information stored in Python 
objects.  Abstractly, object values are the mostly implementation- and 
even language-independent information that we wish to manipulate.  Note 
that concrete types are somewhat implementation dependent and ids are 
implementation and session dependent.

Bools represent binary choices, not 'truth' per se.  We call the choices 
'True' and 'False' because that (with or without capitals) is the 
default binary choice in propositional logic.  For numbers, 0 versus not 
0 is often an important choice.  Ditto for 'empty' versus 'not empty' 
for collections.
