Service (opening words, reading, closing words) to an address by Kenneth Davidson, economics and public policy write for The Age, August 8, 2010

Practical men, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist.
John Maynard Keynes "The General Theory of Employment, Interest and Money"
