“To the gross senses the chair seems solid and substantial. But the gross senses and be refined by means of instruments. Closer observations are made, as the result of which we are forced to conclude that the chair is “really” a swarm of electric charges whizzing about in empty space. … While the substantial chair is an abstraction easily made from the memories of innumerable sensations of sight and touch, the electric charge chair is a difficult and far-fetched abstraction from certain visual sensations so excessively rare (they can only come to us in the course of elaborate experiments) that not one man in a million has ever been in the position to make it for himself. The overwhelming majority of us accept the electric-charge chair on authority, as good Catholics accept transubstantiation.”

Billy seems to be using the expression "electric chair" when he means a lie detector.

Variant: You'd be surprised how many people want to hang an electric chair on their living-room wall. Specially if the background color matches the drapes.

As quoted in Marie Deparis (2009), "Mounir Fatmi: Gardons Espoir / Keeping Faith" (bilingual exhibition notice, as a retranslation from the French "On n'imagine pas le nombre de personnes qui accrocheraient chez elles le tableau de la chaise électrique, surtout si les coloris de la toile s'harmonisent avec les rideaux.")

The Rickover Effect (1992)
Context: The Quakers have an excellent approach to thinking through difficult problems, where a number of intelligent and responsible people must work together. They meet as equals, and anyone who has an idea speaks up. There are no parliamentary procedures and no coercion from the Chair. They continue the discussion until unanimity is reached. I want you guys to do that. Get in a room with no phones and leave orders that you are not to be disturbed. And sit there until you can deal with each other as individuals, not as spokesmen for either organization.
