“It is procedure that governs the routine internal and external relationships - between one individual and another; between one organizational unit and another; between one process and another; between one skill or technique and another; between one function and another; between one place and another; between the organization and the public; and between all combinations and permutations of these. It is by means of procedure that the day-to-day work of government is done-mail sorted, routed and delivered; deeds recorded; accounts audited; cases prosecuted; protests heard; food inspected; budgets reviewed; tax returns verified; data collected; supplies purchased; property assessed; inquiries answered; orders issued; investigations made; and so forth endlessly.”

Variant: The most important reason for going from one place to another is to see what's in between, and they took great pleasure in doing just that.

Gravity's Rainbow (1973)
Context: No, as none of these, but instead a point in space, a point hung precise as the point where burning must end, never launched, never to fall. And what is the specific shape whose center of gravity is the Brennschluss Point? Don't jump at an infinite number of possible shapes. There's only one. It is most likely an interface between one order of things and another. There's a Brennschluss point for every firing site. They still hang up there, all of them, a constellation waiting to have a 13th sign of the Zodiac named for it...

remarks (2 May 1956) at a Caltech YMCA lunch forum http://calteches.library.caltech.edu/49/2/Religion.htm
Context: In this age of specialization men who thoroughly know one field are often incompetent to discuss another. The great problems of the relations between one and another aspect of human activity have for this reason been discussed less and less in public. When we look at the past great debates on these subjects we feel jealous of those times, for we should have liked the excitement of such argument. The old problems, such as the relation of science and religion, are still with us, and I believe present as difficult dilemmas as ever, but they are not often publicly discussed because of the limitations of specialization.
