128 ;;Quote: the concept-oriented view of inheritance is based on classification in taxonomic systems; models part of the real world
128 ;;Quote: the program-oriented view of inheritance is based on extension and substitutability; can replace an object with an object of any subclass
128 ;;Quote: is-a inheritance in object-oriented programming has two very different interpretations
128 ;;Quote: polymorphism is useful because it allows the uniform manipulation of objects by methods of a common superclass
129 ;;Quote: the is-a relation does not hold for particular instances of squares and rectangles; e.g. a rectangle of height 5 and width 20
129 ;;Quote: object-oriented classes are really types that describe particular objects rather than abstract concepts; shouldn't use "class"
130 ;;Quote: object-oriented inheritance is an extension mechanism, not a specialization or classification mechanism
