If you look at the Tractatus of Wittgenstein, you will see that it fully anticipates what we know now as hypertext...
this fact of form makes the Tractatus very suitable for presentation as hypertext.
For the limited domain of the subjects covered in the Tractatus, Wittgenstein's mind was able to grow a tree-like structure by which he could organize and present his ideas. One of the interesting features of biological trees is that the individual branches of a tree seldom fuse with each other to create loops. For the material of the new book, Philosophical Investigations, Wittgenstein could find no way of forcing that material into the limited topology of a tree.
What Wittgenstein needed was the complete freedom that is provided by hypertext computer files that can point to each other in endlessly complex loops.
