As quoted in Management and the Computer of the Future (1962) by Sloan School of Management, p. 273
Context: We must include in any language with which we hope to describe complex data-processing situations the capability for describing data. We must also include a mechanism for determining the priorities to be applied to the data. These priorities are not fixed and are indicated in many cases by the data.
Thus we must have a language and a structure that will take care of the data descriptions and priorities, as well as the operations we wish to perform. If we think seriously about these problems, we find that we cannot work with procedures alone, since they are sequential. We need to define the problem instead of the procedures. The Language Structures Group of the Codasyl Committee has been studying the structure of languages that can be used to describe data-processing problems. The Group started out by trying to design a language for stating procedures, but soon discovered that what was really required was a description of the data and a statement of the relationships between the data sets. The Group has since begun writing an algebra of processes, the background for a theory of data processing.
Clearly, we must break away from the sequential and not limit the computers. We must state definitions and provide for priorities and descriptions of data. We must state relationships, not procedures.

On the loss of some of his brothers, in a letter to his brother John, as quoted in William the Silent (1897) by Frederic Harrison, p. 76

It is the choicest compliment that has ever been paid us, and the most gratifying to our feelings. It is simple, direct, gracefully phrased: it always sounds well — In God We Trust. I don't believe it would sound any better if it were true. And in a measure it is true — half the nation trusts in Him. That half has decided it.

2014, Review of Signals Intelligence Speech (June 2014)
Context: There was a recognition by all who participated in these reviews that the challenges to our privacy do not come from government alone. Corporations of all shapes and sizes track what you buy, store and analyze our data, and use it for commercial purposes; that’s how those targeted ads pop up on your computer and your smartphone periodically. But all of us understand that the standards for government surveillance must be higher. Given the unique power of the state, it is not enough for leaders to say: Trust us, we won’t abuse the data we collect. For history has too many examples when that trust has been breached. Our system of government is built on the premise that our liberty cannot depend on the good intentions of those in power; it depends on the law to constrain those in power.
