Four principles of object oriented programming [video]

Video description:

"Abstraction, Polymorphism, Inheritance and Encapsulation… Yikes! What the heck does all that mean and why should anyone care?

Programming is full of jargon. Object Oriented Programming takes jargon to a whole new level. But even so, that list of the “four fundamentals of object oriented programming” is missing something important. In this video, I explain what the four principles are. And I then explain why they are making a big deal out of something that is essentially quite simple."

Later in the video:

"I'd say polymorphism is probably a hundred dollar word for a 50 Cent idea. These days computer science teachers and writers have extended the meaning of polymorphism to such an extent that it's often hard to figure out what the heck they're trying to describe"

I'll concede that inheritance is a principle of OO, but I'd love to see a video try to make the case that the other three apply specifically to OO - as opposed to all programming languages.
