“Preventing and fighting corruption and waste is an important, urgent and long-term task of extreme difficulty and complexity. To enhance the efficiency of the work, timely detection, investigation and handling of offences plays a decisive role.”

Martin Luther King Day address, Constitution Hall, Washington, D.C. (16 January 2006) http://www.realclearpolitics.com/Commentary/com-1_16_06_Gore_pf.html.
Context: In the Congress as a whole-both House and Senate-the enhanced role of money in the re-election process, coupled with the sharply diminished role for reasoned deliberation and debate, has produced an atmosphere conducive to pervasive institutionalized corruption.
The Abramoff scandal is but the tip of a giant iceberg that threatens the integrity of the entire legislative branch of government.

Quotes, The Assault on Reason (2007)
Context: History will surely judge America's decision to invade and occupy a fragile and unstable nation that did not attack us and posed no threat to us as a decision that was not only tragic but absurd. Saddam Hussein was a brutal dictator, to be sure, but not one who posed an imminent danger to us. It is a decision that could have been made only at a moment in time when reason was playing a sharply diminished role in our national deliberations.

Nobel interview http://nobelprize.org/mediaplayer/index.php?id=425 with Professor Georges Charpak by Joanna Rose, science writer, 6 December 2001.
Context: History of science played a very important role for me. Before I knew well how to do an experiment, I knew why Joliot has missed the neutron, why his wife missed the fission, why they succeeded in having artificial radioactivity, and even why they almost missed the other things, by doing very nice experiments, but didn't come to the conclusion. That is science. Science is doubt, is research. It is not something which is – and that is the danger of teaching – which is too academic and which the people explain you it is like the logic thing that comes out of the computer, which is not true. You have intuition, you have passion.
