If you were planning to build an entire project around multiple
inheritance, forget it.. However if you have a one off where you think
Multiple Inheritance could help you might consider adopting the
Decorator Pattern (Gamma et al).. The decorator pattern is like this:
 

type TPerson = class( TObject )
  private
    fName : string;
  public
    property Name : string read fName write fName;
end;
 
 

type TOccupation = class( TObject )
   private
      fName : string;
    public
      property Name : string read fName write fName;
end;

Type TEmployedPerson = class( TPerson )
  private
    fOccupation : TOccupation;
  public
    property Occupation : TOccupation read fOccupation write
fOccupation;
end;
 

The motivation for the Decorator Pattern is: "Attach addition
responsiblities to an object dynamically. Decorators provide a flexible
alternative to subclassing for extending functionality"
