Knowledge, at its core, is simply a description of one thing in terms of another. Jane is a person, Jane lives in Boston. We call the verb “transitive” in these cases because there is an object (“person”) to go along with the subject. But Jane can participate in activities on her own — Jane works, Jane sleeps. We call the verb “intransitive” for those statements, but they belie the fact that a lot is going on underneath — Jane works at a company, Jane performs a task at that company, Jane’s shift begins at a certain time and ends at a later time, etc. Ultimately, all knowledge involves linking one thing to another.
Factango demonstrates how you can step from one thing to another through a succession of interlinked facts. Go there and enter something in the Find field at top. Then click on any of the words below and move from one thing to another, from one fact to another. One thing is connected to another.
