No, if UNIVERSAL were an abstract class, then the can() and isa() methods would be unimplemented (that is what makes a class abstract -- none of its methods are implemented, the class consists of only a interface definition and no implementation) and you would be required to implement them yourself in any class you build that inherits from UNIVERSAL (which would be all classes since all classes inherit from UNIVERSAL implicitly).
