It's the base class' job to define the API that derived classes will be 
overriding and the derived classes' choice as to exactly which functions they 
override (assuming that they're not abstract and therefore have to be 
overridden). That doesn't mean that the base class can't or shouldn't have 
other functions which are not intended to be overridden. Nothing about 
Liskov's substitution principle requires that the entire API of the base class 
be polymorphic.
