> In my opinion after a certain level, all knowledge is multi-disciplinary, and the boundaries of what constitutes roots, branches, leaves is extremely fuzzy. Also the distinction between theory and practice makes the boundaries even fuzzier.

Of course. I think this is the point of this learning style. After learning the first principles of various topics, the broad web that is higher knowledge is available to you.

Suppose, for instance, I wanted to learn how computer science worked from first principles. This study involves math, electronics, physics, and many, many more subjects. To accomplish this, I would pick one of the key, pure tenets and learn it. Let's say I choose math. I would then learn the key things I need to know about math and then move to electronics and physics, and etc. After knowing these, I could confidently approach the "web" of computer science because I have anchorpoints.

I think it's safe to view higher knowledge as a web supported by the anchors of "pure" subjects. After a while, these higher subjects are built upon and become pure topics themselves. Epistemology and the classification of knowledge is really a fascinating topic.
