Where to draw the line?

This is, as Gordon Brander demonstrates, ancient wisdom, but it is immediately practical in today's world: "Compositionality is the principle that a system should be designed by composing together smaller subsystems, and reasoning about the system should be done recursively on its structure." It's the principle that underlies the Cartesian method; it's the idea that informs the development of learning objects and open educational resources. It's how software is developed. But, as Brander notes, where you draw the lines matters. Once drawn, they are almost never redrawn. We need, as much as possible, to follow the natural divisions in the space where we're working.
