Question: Several people view the four foundational factors of object-orientation as abstraction, encapsulation, inheritance, and polymorphism. There is a certain purity in being minimal. Various language designers have emphasized these four elements differently. In some object-oriented languages these four have been minimized to three. Of these four, if you could de-emphasize one, i.e. you felt it was essential to what object-orientation is all about, which would it be? And why? Explain your answer.
