Revere quotes John Kenneth Galbraith at some length, on the "no-business meeting... scholars, who are great devotees of the no-business meeting, rely heavily on the exchange-of-ideas justification. To them the exchange of ideas is an absolute good. Any meeting at which ideas are exchanged is, therefore, useful. This justification is nearly ironclad. It is very hard to have a meeting of which it can be said that no ideas were exchanged."
