It says "All that is necessary for the triumph of evil is that good men do nothing." is the most famous Burke quote, but is a misattribution!

Also on the page is this wonderful comment.

It has always been with me, a test of the sense and candour of any one belonging to the opposite party, whether he allowed Burke to be a great man.
William Hazlitt

Hazlitt also had good things to say about Godwin.
