A few years back, I had the great pleasure of serving with Bruce Dravis as Co-Chairman of the Corporations Committee of the Business Law Section of the California State Bar.  The American Bar Association's Business Law Section will soon be releasing a new and updated version of Bruce's book on independent directors - The Role of Independent Directors in Corporate Governance.  Information on how to order Bruce's book is available here.

The above quotation is attributed to Benjamin Jowett, a former Master of Balliol College, Oxford and translator of Plato.   The Life and Letters of Benjamin Jowett, Vol. 1, p. 248 (Evelyn Abbott and Lewis Campbell, eds. 1897).  Here's a bit of Balliol Rhyme about Master Jowett: 

First come I. My name is J-w-tt.

There's no knowledge but I know it.

I am Master of this College,

What I don't know isn't knowledge.
