One definition of knowledge

The way the word knowledge is used by many intellectuals often arbitrarily limits what verified information is to be considered knowledge. This arbitrary limitation of the scope of the word was expressed in a parody verse about Benjamin Jowett, master of Balliol College at Oxford University:

First come I; my name is Jowett.
There’s no knowledge but I know it.
I am master of this college:
What I don’t know isn’t knowledge.

—Thomas Sowell, Intellectuals and Society

(The ‘parody verse’ is generally attributed to Henry Beeching. I have here substituted the original for Sowell’s paraphrase, because the original scans better.)
